    The concentrations of 137 Cs, 134 Cs and 40 K were measured in samples taken from the upper littoral along the Swedish Baltic Sea coast in 1990 and 1991. The results were compared with earlier measurements carried out 1984-1989, and some unpublished data from these years are presented as well. The levels of radiocesium in algae that belong to different algal groups were compared, and the value of different algal species as monitoring organisms for radionuclides in the Baltic Sea was discussed. Suggestions for future monitoring and future research are given. 10 refs, 5 figs, 10 tabs

    Concentrations of polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF), and dioxin-like non-ortho-PCBs were measured in white-tailed sea eagle (WTSE) eagle eggs collected along the Swedish coast of the Baltic Sea during the period 1992-2004. The eggs represent two different subpopulations with significantly different nestling brood sizes; the Baltic Proper (BP) with an approximately normal nestling brood size (1.62), and the south Bothnian Sea (sBS) with reduced nestling brood size (1.22) combined with a significantly higher rate of dead eggs. The aim was to investigate if this difference in reproductive outcome was linked to differences in exposure to dioxin-like compounds. Three eggs collected in Greenland in 2000 were included in the study to provide a reference sea eagle population outside of the Baltic Sea region. The concentrations of ∑PCDD, ∑PCDF and ∑non-ortho-PCB in the two subpopulations from the Baltic Sea (BS) region ranged from 0.41-4.1, 1.2-5.3 and 180-970 ng/g lipids, respectively, while in the Greenland population the ranges were 0.11-0.16, 0.22-0.33 and 57-83 ng/g lipid, respectively. 2,3,4,7,8-PCDF was the predominant congener in all areas and accounted for on average 31-49% of the total ∑PCDD/F concentrations. The total toxic equivalents (TEQ) in sBS WTSEs were higher (approximately 39 ng TEQ/g lipid) than reported in eggs for many other birds, and the major contributors to the TEQ in the Baltic Sea were the non-ortho-PCBs. A principal component analysis (PCA) showed a difference in congener pattern between the two Baltic regions that was statistically significant (Hotelling's T(2) test). We found no significant differences in the total TEQ between the two populations (sBS-BP) and thus no evidence was found linking the reproductive impairment in WTSE in sBS to the concentrations of PCDD/Fs or non-ortho-PCBs in the eggs.

    The aim of the project was to compile a single database with quantitative data collected by SCUBA divers from the whole Swedish Baltic Sea coast. Data of plant and animal biomass, together with position, depth and type of substrate from 19 areas along the Swedish coast from the county of Blekinge to Kalix in the Bothnian Bay were compiled in a single database. In all, the database contains 2,170 records (samples) from 179 different stations where in total 161 plant and 145 animal species have been found. The data were then illustrated by the geographical distribution of plant and animal biomass and by constructing a model to estimate future changes of the plant and animal communities in the Graesoe area in the Aaland Sea applying GIS-techniques. To illustrate the opportunities of the database the change of the composition of benthic plant and animal biomass with salinity was calculated. The proportion of marine species increased with increasing salinity and the benthic biomass was at its highest in the southern Baltic proper. Quantitative data from Grepen and the Graesoe-Singoe area were used to calculate present biomass in the Graesoe area. A scenario of the change in biomass distribution and total biomass caused by shore displacement was created using data from Raaneaa and Kalix in the Bothnian Bay. To map the biomass distribution the material was divided into different depth intervals. The change of biomass with time was calculated as a function of salinity change and reduction of the available area, caused by shore displacement. The total biomass for all plants and animals in the investigated area was 50,500 tonnes at present. In 2,000 years the total biomass will be 25,000 tonnes and in 4,000 years 3,600 tonnes due to shore displacement causing a decrease in both salinity and available substrate.To make an estimate of the species distribution and a rough estimate of their biomass in an unknown geographic area, the type of substrate, the depth and the wave

    1991-01-01

    Individual doses to critical groups from a continuous unit release of nuclides from high-level waste to a coast area were calculated. The selection of nuclides for this study was based on experience of their importance from a radiological point of view. The coastal area should be representative for average conditions along the Swedish Baltic coast. The costal area was simulated in the model by compartments for water and sediment, respectively. Six exposure pathways for activity from the water and sediment reservoirs were considered. The ecosystem was assumed to be similar to present conditions in Sweden. This was also the case concerning diet and living habits. In addition, the doses from naturally occurring nuclides in the uranium decay chains were calculated, based on natural levels. The calculations were carried out with the BIOPATH and PRISM codes. The latter code was used to obtain the uncertainty in the results due to the uncertainty in the input parameter values.

  6. Swedish political attitudes towards Baltic independence in the short 20th century

    Kuldkepp, M.

    2016-01-01

    This article considers the history of Swedish attitudes towards Baltic independence in the period in the so-called short 20th century (1914-1991), focusing primarily on the years when Baltic independence was gained (1918-1920) and regained (1989-1991). The former period was characterized by Swedish skepticism towards the ability of the Baltic states to retain their independence long-term, explainable by the Swedish political elites’ conviction that the weakening of Russia in the First World W...

  7. 137Cs dating of laminated sediments in Swedish archipelago areas of the Baltic Sea

    International Nuclear Information System (INIS)

    Meili, M.; Jonsson, P.; Carman, R.

    1998-01-01

    In deep off-shore areas of the Baltic Sea, sediment accumulation rates are typically on the order of one or a few millimeters per year, and even less in consolidated sediments, based on laming counts and radiometric dating. In lacustrine and marine basins, the highest sedimentation rates are usually found in the deepest part, since sediments and associated contaminants are known to be gradually 'focused' from shallow to deep areas by resuspension. Accordingly, net sedimentation in coastal areas is usually low or absent due to strong erosion forces. On the other hand, coastal sediments are likely to be important in controlling the fate and turnover of contaminants that are released into coastal waters. Since little is known about the turnover of coastal sediments, in particular for heterogeneous semi-enclosed areas such as the Baltic archipelagos, a study of sediment accumulation rates has been initaited, with a focus on areas where erosion is likely to be minimal. The study is part of a project focusing on the relationship between eutrophication and contaminant cycling (EUCON). 88 sediment cores were collected during summer 1996 from accumulation bottoms of 18 more or less protected bays in archipalgo areas along the swedish coast of the Baltic Sea

    2017-12-01

    We report on results of the Research Training Group Baltic TRANSCOAST. The overall aim of Baltic TRANSCOAST is to enhance our knowledge of the shallow coast ecocline. How is the marine coastal zone influenced by terrestrial processes? How is the terrestrial coastal zone influenced by marine processes? These questions lead our research within the three research fields covering hydro-dynamic, (bio)geochemical and biological processes. Regarding the hydro-dynamics we assess how the peatland's water balance, the current dynamics and hydraulic properties of the marine sediments and the subsoil influence sea water intrusions into the peatland and/or submarine groundwater discharge into the Baltic Sea. With respect to (bio)geochemical processes we address how (bio)geochemical transformation processes both in the marine and the terrestrial part of the coast are influenced by water and matter inputs from the respective other coastal domain. Finally, reagrding the biological processes, we are interested in revealing how the primary production and the composition of the micro- and macro-phytobenthos in the shallow Baltic Sea influence matter transformation processes. The integrative approach of Baltic TRANSCOAST allows us to get to grips with questions that are otherwise hard to tackle. For instance, we address how the pore water constituents drive microbial processes and the deposition of nutrients and and how they are impacted by sediment resuspension and translocation. We investigate how the hydrology of the peat layers interferes with the generation of trace gases and investigate the role of the nearby Warnow river and its plume and how this changes under the impact of wind direction and wind strength. For the latter we rely on data and models. Further, as a common basis for all topics addressed in Baltic TRANSCOAST we established the geology of the study area and learned that regional variability may play a major role in shaping the processes under study.

    2016-09-01

    Full Text Available The present study provides data on the distribution of 128 bee species on the Polish Baltic coast. This brings the total number of species of Apiformes in this region to 164, including those that I reported earlier. The bee fauna of the Polish coast is characterized by a very high proportion of bumblebees and cuckoo bees (locally up to 70-80% of the total catch, and the dominant proportion of Megachilidae, especially Megachile species. The species diversity and dominance structure of the Apiformes differ between the western coast (a very high proportion of bumblebees and the eastern coast (a large number of dominant species. These results confirm my earlier hypothesis regarding the maritime-continental gradient of bumblebee abundance, indicating that the densities of these insects are higher in NW Poland. This study is the first to assess bee densities on coastal dunes in Poland.

    2009-07-01

    Metal pollution is viewed as a modern problem that began in the 19th century and accelerated through the 20th century; however, in many parts of the globe this view is wrong. Here, we studied past waterborne metal pollution in lake sediments from the Bergslagen region in central Sweden, one of many historically important mining regions in Europe. With a focus on lead (including isotopes), we trace mining impacts from a local scale, through a 120-km-long river system draining into Mälaren--Sweden's third largest lake, and finally also the Baltic Sea. Comparison of sediment and peat records shows that pollution from Swedish mining was largely waterborne and that atmospheric deposition was dominated by long-range transport from other regions. Swedish ore lead is detectable from the 10th century, but the greatest impact occurred during the 16th-18th centuries with improvements occurring over recent centuries, i.e., historical pollution > modern industrial pollution.

  15. The structure and stratigraphy of the sedimentary succession in the Swedish sector of the Baltic Basin: New insights from vintage 2D marine seismic data

    2016-04-01

    We present five interpreted regional seismic profiles, describing the full sedimentary sequence across the Swedish sector of the Baltic Sea. The data for the study are part of an extensive and largely unpublished 2D seismic dataset acquired between 1970 and 1990 by the Swedish Oil Prospecting Company (OPAB). The Baltic Basin is an intracratonic basin located in northern Europe. Most of the Swedish sector of the basin constitutes the NW flank of a broad synclinal depression, the Baltic Basin. In the SW of the Swedish sector lies the Hanö Bay Basin, formed by subsidence associated with inversion of the Tornquist Zone during the Late Cretaceous. The geological history presented here is broadly consistent with previously published works. We observe an area between the Hanö Bay and the Baltic Basin where the Palaeozoic strata has been affected by transpression and subsequent inversion, associated with the Tornquist Zone during the late Carboniferous-Early Permian and Late Cretaceous, respectively. We propose that the Christiansø High was a structural low during the Late Jurassic, which was later inverted in the Late Cretaceous. We suggest that a fan shaped feature in the seismic data, adjacent to the Christiansø Fault within the Hanö Bay Basin, represents rapidly deposited, coarse-grained sediments eroded from the inverted Christiansø High during the Late Cretaceous. We identify a number of faults within the deeper part of the Baltic Basin, which we also interpret to be transpressional in nature, formed during the Caledonian Orogeny in the Late Silurian-Early Devonian. East of Gotland a number of sedimentary structures consisting of Silurian carbonate reefs and Ordovician carbonate mounds, as well as a large Quaternary glacial feature are observed. Finally, we use the seismic interpretation to infer the structural and stratigraphic history of the Baltic and Hanö Bay basins within the Swedish sector.

  16. Nord Stream, the German-Russian oil pipeline under the Baltic Sea from the Swedish point of view

    International Nuclear Information System (INIS)

    Crone, Olivier

    2007-01-01

    Nord Stream is a 1.200 km long gas pipeline project between Russia and Germany through the Baltic Sea. It crosses the Swedish, Danish, and Finnish economic zones, and, at mid-way, comprises a control platform about which any traffic will be forbidden within a radius of 500 m. After having recalled some design aspects of this project, the author discusses whether it results in some energetic benefits for Sweden where the project has been a matter of debates on environmental and safety issues. It appears that Sweden is not interested at all in importing fossil energies, and that politicians are opposed to this project, but have no influence on it as the pipeline does not cross Swedish territorial waters. After having evoked the role of Gazprom as energetic weapon of the Russian foreign policy, the author discusses safety issues related to this pipeline and its control platform, and environmental risks as they are perceived by Sweden. Sweden indeed perceives the project infrastructure as being possibly used as a spying tool. As far as environmental issues are concerned, Nord Stream is to submit an environmental impact assessment to Denmark, Finland, Sweden, Germany and Russia. As a Swedish law could constrain and even impede the project, some alternate tracks are already envisaged and studied for the pipeline in order to minimise the environmental impact

    2002-12-01

    Full Text Available This paper presents the results of an attempt to reproduce, with theaid of a numerical circulation model, the hydrological conditions observedin the coastal area of the southern Baltic in September 1989.A large fall in surface layer seawater temperature was recordedin September 1989 at two coastal stations in the vicinity ofKolobrzeg and Wladyslawowo. This upwelling-like phenomenon was assumed tobe related to the specific anemobaric situation in September 1989,however typical of this phenomenon to occur along the Polish Baltic coast(Malicki & Mietus 1994. A three-dimensional (3-D sigma-coordinatebaroclinic model of the Baltic Sea, with a horizontal resolution of~5 km and 24 sigma-levels in the vertical, was applied to investigatewater circulation and thermohaline variability. Hindcastnumerical simulation showed that the model provided a good reproductionof the temporal history of the surface seawater temperature and theduration of the upwelling-like fall, but that the model results wereunderestimated. The maxima of this large fall in the surface layertemperature at both coastal stations are closely related to the phase ofchange of the upwelling-favourable wind direction to the opposite one.The results of simulation runs showed details of upwelling developmentdue to wind field fluctuations in time and differences in shaping thetemperature and current patterns in conjunction with the variations intopography and coastline features in some areas along the Polish coast.Two different hydrodynamic regimes of water movements along the coastresulting from topographical features (the Slupsk Bank can be distinguished.From the model simulation the specific conditions for the occurrence anddevelopment of upwelling at the eastern end of the Polish coast(in the vicinity of Wladyslawowo can be deduced.

    1992-01-01

    Sweden rose from relative obscurity to become the most powerful nation in Northern Europe during the period 1560-1720 based on its prosperous metal industry: silver, copper, and steel. This essay addresses this period of history from an energy perspective and suggests, as others have, that the surplus energy of a nation is its basis for power. Sweden's energy came mainly from its forests which supplied its mines with wood and its metal-works with charcoal. This energy system, including hydropower, animal and man power, is analyzed using one of the thousands of charcoal-burners as a model for the main energy input: charcoal. The principles of sustainable use of Swedish forests are also addressed in a historical perspective. 6 figs., 9 tabs., 1 app., 40 refs

  19. Stakeholder-based evaluation categories for regional climate services - a case study at the German Baltic Sea coast

    Meinke, Insa

    2017-08-01

    In this study, categories, dimensions, and criteria for evaluating regional climate services are derived by a participatory approach with potential service users at the German Baltic Sea coast. The development is carried out within nine face-to-face interviews conducted with decision makers, working in climate sensitive sectors at the German Baltic Sea coast. Three main groups of categories were localized which seem to matter most to the considered stakeholders and which seem to be crucial evaluation categories for regional climate services: (1) credibility, (2) relevance, and (3) appropriateness. For each of these evaluation categories several dimensions emerged, indicating certain perspectives of stakeholder demands. When summarizing these evaluation categories and their dimensions, 13 evaluation criteria for regional climate services can be derived (see Table 1). The results show that stakeholders do mainly address components other than those found in the literature (e.g. inputs, process, outputs, outcomes, and impacts). This might indicate that an evaluation, following solely literature-based (non-participative) components, is not sufficient to localize deficiencies or efficiencies within a regional climate service, since it might lead to results which are not relevant for potential users.

    2016-06-01

    Full Text Available Digital photogrammetry and remote sensing solutions applied under the project and combined with the geographical information system made it possible to utilize data originating from various sources and dating back to different periods. Research works made use of archival and up-to-date aerial images, satellite images, orthophotomaps. Multitemporal data served for mapping and monitoring intermediate conditions of the Baltic Sea shore zone without a need for a direct interference in the environment. The main objective of research was to determine the dynamics and volume of sea shore changes along the selected part of coast in the period of 1951-2004, and to assess the tendencies of shore development in that area. For each of the six annual data sets, the following were determined: front dune base line, water line and the beach width. The location of the dune base line, which reflects the course of the shoreline in a given year was reconstructed based on stereoscopic study of images from each annual set. Unidirectional changes in the period of 1951-2004 occurred only within 10% of the examined shore section length. The examined shore is marked by a high and considerable dynamics of changes. Almost half of the shore, in particular the middle coast shows big changes, in excess of 2 m/year. The limits of shoreline changes ranged from 120 to -90 m, and their velocity from 0 to 11 m/year, save that the middle and west parts of the examined coast section were subjected to definitely more intense shore transformations. Research based on the analysis of multitemporal aerial images made it possible to reconstruct the intermediate conditions of the Baltic Sea shoreline and determine the volume and rate of changes in the location of dune base line in the examined period of 53 years, and to find out tendencies of shore development and dynamics.

  1. Characterization of the Lower Cambrian sandstone aquifer in the Swedish Baltic Sea area - assessment regarding its potential suitability for storage of CO2

    Erlström, M.; Sivhed, U.

    2012-04-01

    In the Baltic region the Cambrian sandstone is considered to have great economic value concerning its aquifer and reservoir properties. Its potential as petroleum reservoir is well known, especially from the Polish, Lithuanian and Russian sectors of the Baltic Sea where oil and gas has been found in anticline traps in the sandstone sequence. Offshore exploration in the Swedish sector has so far not encountered any significant findings of oil and gas. However, the extensive exploration has generated data, which is now being used for assessing the overall properties regarding suitability for storage of CO2. The Swedish primary industry has a great interest in finding potential sites for storage of CO2. A suitable site in the Baltic Sea would be a most favourable alternative in comparison to more remote alternatives such as deep saline aquifers in the North Sea. The Lower Cambrian is in the Swedish sector of the Baltic Sea composed of three main sandstone units varying in thickness between 5 and 50 m occurring within an up to 250 m thick Cambrian sequence dominated by fine-grained terriclastic sediments. The limit of Lower Palaeozoic sequence in the Baltic area is today defined by erosional truncation because of the gently dipping Lower Palaeozoic sequence. To the north and northwest, the limit is found in the Pre-Quaternary, whereas the erosional limit is deeply buried beneath Permian and Mesozoic sediments to the south. Here the Lower Palaeozoic limit is buried to depths reaching more than 2 km. The Cambrian sequence in the distal parts of the Swedish sector occurs at depths of c. 1300 m while it constitutes the bedrock surface in a narrow zone trending from Öland to the north of of Gotland. Sandstone beds constitute 40-60% of the total Cambrian sequence. The main sandstone units have a regional distribution of several thousands of square kilometres. The up to 50 m thick Faludden sandstone member exhibits the best reservoir properties including porosities in the

  2. Radiocaesium and polonium in seals from Swedish coastal waters

    2004-01-01

    Radiocaesium, 137 Cs (T 1/2 = 30 a) and 210 Po (T 1/2 = 138 d) have been studied in tissues (muscle, liver, kidney and gonads/ovaries) from a large number of seals from the Baltic Sea and the Swedish west coast during 1995-2002. The Baltic Sea is a marginal sea with long residence time for dissolved compounds. Concentrations of radiocaesium increased 10 fold in the Baltic Sea following the Chernobyl accident, while concentrations of polonium can be supposed to be in equilibrium except for seasonal variations. The major food for seals in the Baltic proper is fish, while at the west coast other food stuff such as crustaceans play an important role. By supposing that the seals consume 5% of their body-weight per day and by using known data for caesium and polonium in fish the biological half-life in seals is estimated to 20 days for Caesium and 35 days for Polonium. Radiocaesium is evenly distributed in the organs of the seals and was about 100 Bq kg -1 in the Baltic Sea while at the west coast the concentrations were significantly lower, about 5-30 Bq kg -1 . Polonium shows the highest concentrations in kidney, about 100-200 Bq kg -1 d.w. in the Baltic sea and higher concentrations 100-1000 Bq kg -1 at the west coast. This reflects clearly the differences in food choice/availability in the different areas. The estimated maximal doses were 76 μSv per year to muscle from 137 Cs and 6.8 mSv from 210 Po to kidney. Seals constitute a good bio-marker for radioactivity in Swedish coastal waters. Concentration factors are higher for radiocaesium in the Baltic Sea due to lower salinity and consequently higher concentrations in fish compared to other areas, but lower for polonium than in areas where crustaceans also constitute an important foodstuff.

  4. Food and habitat resource partitioning between three estuarine fish species on the Swedish west coast

    Thorman, Staffan

    1983-12-01

    In 1978 the food and habitat resource partitioning of three small and common fish species, viz. Pomatoschistus microps (Krøyer), Gasterosteus aculeatus (L.) and Pungitius pungitius (L.) were studied in river Broälven estuary on the Swedish west coast (58°22'N, 11°29'E). The area was divided into three habitats, based on environmental features. In July, September, and October stomach contents and size distribution of each species present were analysed. In July there was high food and habitat overlap between the species. Interference interactions probably occurred between some size classes of P. microps and the other two species. P. pungitius was exposed to both intra- and interspecific interactions. In September the food and habitat overlaps between G. aculeatus and P. pungitius were high, while both had low food and habitat overlaps in relation to P. microps. Interactions between G. aculeatus and P. pungitius were probably influenced by more severe abiotic conditions in one habitat, which caused lower abundances there, and higher abundances in the other two habitats. In October no interactions were observed. These results indicate that competition for food at least temporarily determines the species distribution in a temperate estuary, and that estuarine fish populations are sometimes food limited.

    Lakes situated on the coast of the southern Baltic function in different conditions than those in which typically inland reservoirs occur. They are situated in the contact zone of two environments: land and sea. These reservoirs together with their direct catchments form specific hydrographic arrangement, in which the course of physical, chemical and biological processes depends on the fact which of these two environments exerts a stronger influence at a given moment. This is important as the lakes situated in the shore zone of the southern Baltic are not exposed to phenomena caused by constant tides, as it is the case in open seas (Ataie-Ashtiani et al., 1999), but only to extreme hydrometeorological conditions, which lead to the formation of the phenomenon of intrusions of sea waters and of damming the free outflow of potamic waters (Demirel, 2004; Cieśliński, Drwal, 2005). What should also be remembered are the local hydrographic, hydrological and morphometric conditions. As a result of intrusions, in the waters of coastal lakes, apart from inland waters there are also waters of sea origin. The proportions of these genetically distinct waters are variable and differ in individual lakes (Grassi, Netti, 2000; Drwal, Cieśliński, 2007). Despite the difference in the causal factor triggering the phenomenon of salt water intrusions, the effect is usually the same as that observed, for instance, in lakes and lagoons of seas with tides (Ishitobi et al., 1999; De Louw, Oude Essink, 2001) and poorly flushed lagoon (Hsing-Juh et al., 2006) or estuaries (Uncles et al., 2002), though the scale of qualitative changes is greater in the case of open seas than in half-closed and closed seas. The status of the research carried out so far enables proposing a hypothesis that chlorides concentrations, as the best indicators for establishing the occurrence of the phenomenon of intrusions, depend not only on the meteorological factor but in some of the lakes on various

  6. On the comparability of knowledge transfer activities - a case study at the German Baltic Sea Coast focusing regional climate services

    In this article the comparability of knowledge transfer activities is discussed by accounting for external impacts. It is shown that factors which are neither part of the knowledge transfer activity nor part of the participating institution may have significant impact on the potential usefulness of knowledge transfer activities. Differences in the potential usefulness are leading to different initial conditions of the knowledge transfer activities. This needs to be taken into account when comparing different knowledge transfer activities, e.g., in program evaluations. This study is focusing on regional climate services at the German Baltic Sea coast. It is based on two surveys and experiences with two identical web tools applied on two regions with different spatial coverage. The results show that comparability among science based knowledge transfer activities is strongly limited through several external impacts. The potential usefulness and thus the initial condition of a particular knowledge transfer activity strongly depends on (1) the perceived priority of the focused topic, (2) the used information channels, (3) the conformity between the research agenda of service providing institutions and information demands in the public, as well as (4) on the spatial coverage of a service. It is suggested to account for the described external impacts for evaluations of knowledge transfer activities. The results show that the comparability of knowledge transfer activities is limited and challenge the adequacy of quantitative measures in this context. Moreover, as shown in this case study, in particular regional climate services should be individually evaluated on a long term perspective, by potential user groups and/or by its real users. It is further suggested that evaluation criteria should be co-developed with these stakeholder groups.

    Eradication and population reductions are often used to mitigate the negative impacts of non-native invasive species on native biodiversity. However, monitoring the effectiveness of non-native species control programmes is necessary to evaluate the efficacy of these measures. Genetic monitoring could provide valuable insights into temporal changes in demographic, ecological, and evolutionary processes in invasive populations being subject to control programmes. Such programmes should cause a decrease in effective population size and/or in genetic diversity of the targeted non-native species and an increase in population genetic structuring over time. We used microsatellite DNA data from American mink (Neovison vison) to determine whether the removal of this predator on the Koster Islands archipelago and the nearby Swedish mainland affected genetic variation over six consecutive years of mink culling by trappers as part of a population control programme. We found that on Koster Islands allelic richness decreased (from on average 4.53 to 3.55), genetic structuring increased, and effective population size did not change. In contrast, the mink population from the Swedish coast showed no changes in genetic diversity or structure, suggesting the stability of this population over 6 years of culling. Effective population size did not change over time but was higher on the coast than on the islands across all years. Migration rates from the islands to the coast were almost two times higher than from the coast to the islands. Most migrants leaving the coast were localised on the southern edge of the archipelago, as expected from the direction of the sea current between the two sites. Genetic monitoring provided valuable information on temporal changes in the population of American mink suggesting that this approach can be used to evaluate and improve control programmes of invasive vertebrates.

    The Lyse site at the Swedish west coast is an area with an archipelago of rocky islands to the west and an equally rocky mainland to the east. In between there are some open sea areas. As being the responsible project manager for the erection and the operation of a turbine at a site like Lyse, the question arises about characterization of the wind for design or purchase of a wind turbine. Or in other words what wind turbine class has to be used for the design, according to existing standards like for example IEC-1400 ? 3 refs, 10 figs

    We statistically analyse the relationship between the structure of migrating dunes in the southern Baltic and the driving wind conditions over the past 26 years, with the long-term aim of using migrating dunes as a proxy for past wind conditions at an interannual resolution. The present analysis is based on the dune record derived from geo-radar measurements by Ludwig et al. (2017). The dune system is located at the Baltic Sea coast of Poland and is migrating from west to east along the coast. The dunes present layers with different thicknesses that can be assigned to absolute dates at interannual timescales and put in relation to seasonal wind conditions. To statistically analyse this record and calibrate it as a wind proxy, we used a gridded regional meteorological reanalysis data set (coastDat2) covering recent decades. The identified link between the dune annual layers and wind conditions was additionally supported by the co-variability between dune layers and observed sea level variations in the southern Baltic Sea. We include precipitation and temperature into our analysis, in addition to wind, to learn more about the dependency between these three atmospheric factors and their common influence on the dune system. We set up a statistical linear model based on the correlation between the frequency of days with specific wind conditions in a given season and dune migration velocities derived for that season. To some extent, the dune records can be seen as analogous to tree-ring width records, and hence we use a proxy validation method usually applied in dendrochronology, cross-validation with the leave-one-out method, when the observational record is short. The revealed correlations between the wind record from the reanalysis and the wind record derived from the dune structure is in the range between 0.28 and 0.63, yielding similar statistical validation skill as dendroclimatological records.

  11. A statistical approach to coastal upwelling in the Baltic Sea based on the analysis of satellite data for 1990-2009

    Full Text Available A statistical analysis of Baltic Sea upwelling has been carried out to cover, for the first time, the entire sea area for the period 1990-2009. Weekly composite SST maps based on NOAA/AVHRR satellite data were used to evaluate the location and frequency of upwelling. The results obtained were analysed and compared with earlier studies with excellent agreement. Our study enables the most intense upwelling areas in the entire Baltic Sea to be evaluated. According to the analysis of 443 SST maps, the most common upwelling regions are found off the Swedish south and east coasts (frequency 10-25%, the Swedish coast of the Bothnian Bay (16%, the southern tip of Gotland (up to 15%, and the Finnish coast of the Gulf of Finland (up to 15%. Pronounced upwelling also occurs off the Estonian coast and the Baltic east coast (up to 15%, the Polish coast and the west coast of Rügen (10-15%; otherwise the upwelling frequency was between 5 and 10%. Additionally, simulated SST distributions derived from a Baltic Sea numerical model were analysed for the same period. Furthermore, at specific positions close to the coastline, surface winds based on the SMHI meteorological data base were analysed for the same 20-year period. Wind components parallel to the coast were discriminated into favourable and unfavourable winds forcing upwelling. The obtained frequencies of upwelling-favourable winds fit very well the observed upwelling frequencies derived from satellite SST maps. A positive trend of upwelling frequencies along the Swedish east coast and the Finnish coast of the Gulf of Finland was calculated for the period 1990-2009.

Representative RFLP haplotypes from different parts of the distribution area were sequenced and the phylogeny of European haplotypes and their relations to the North American lineage was described. The four common European haplotypes derive from the ancestral ND1-BBBA...... (rooting the European clade to the North American) by one-step substitutions: AAAA BBBB. The Swedish west- coast populations differ from the geographically close southern Baltic, indicating absence of inward and limited outward gene flow through the Danish straits during the last 8000 years....... Within the Baltic Sea, only three ND1 haplotypes were detected and there was no variation for ND3/4/5/6. In the whole southern Baltic and in lakes Vanern, Ladoga and Onega the haplotype AABA dominated. Proposed postglacial colonization routes to the Baltic Sea are discussed in relation to the haplotype...

    2005-03-01

    Most of the Swedish coastal fisheries are not sustainable from either a social, economic or ecological point of view. We propose the introduction of local fisheries management (LFM) as a tool for restructuring the present large-scale management system in order to achieve sustainability. To implement LFM two questions need to be answered: How to distribute the resource fish among different resource user groups? How to restructure present fisheries management to meet the criteria of sustainability? Starting from these questions we describe possible forms of LFM for Swedish coastal fishery supported by recent research. The biological and social preconditions for restructuring fisheries management are derived from an analysis of the ecological and managerial situation in Swedish fishery. Three types of LFM--owner based, user based, and community based management--are analyzed with regard to the tasks to be carried outin LFM, the roles of management groups, and the definition and optimal size of management areas.

    Some brominated flame retardants, for example poly brominated diphenyl ethers (PBDEs) have been identified as ubiquitous environmental contaminants. The use of the technical PentaBDE product in the European Union has been drastically reduced in the last years and is banned from 2004, while another brominated flame retardant, hexabromocyclododecane (HBCD), continues to be used. In addition to the commercial BFR products, methoxylated PBDEs (MeO-PBDEs) have been identified in biota in the aquatic environment. The origin of the MeO-PBDEs is under discussion. To our knowledge, neither OH-PBDEs nor MeO-PBDEs are commercially produced, nor have they been reported as impurities in brominated technical products or formed as byproducts in any industrial process. However, MeO-PBDEs has been reported to be natural products formed in the marine environment. As regards MeO-PBDEs detected in Baltic fish several factors points in the direction of a natural origin. On the other hand, certain MeO-PBDEs detected in environmental samples could also be metabolites/environmental transformation products of PBDEs. Knowledge of the spatial and temporal trends of the flame retardants in biota can be very useful in identifying sources of emission to the environment and in evaluating the impacts of voluntary restrictions / bans (PBDEs) and ongoing use (HBCD) on environmental contamination. In addition, this knowledge could provide valuable help in identifying the origin of the MeO-PBDEs. To this end, the Swedish Environmental Monitoring Programme on Contaminants in Biota (SEMPC) has incorporated these 3 substance groups into its monitoring of organic contaminants in herring (Clupea harengus). In this contribution we report on the results of the first 4 years.

    Offshore wind energy development promises to be a significant domestic renewable energy source in Latvia. The reliable prediction of present and future wind resources at offshore sites is crucial for planning and selecting the location for wind farms. The overall goal of this paper is the assessment of offshore wind power potential in a target territory of the Baltic Sea near the Latvian coast as well as the identification of a trend in the future wind energy potential for the study territory. The regional climate model CLM and High Resolution Limited Area Model (Hirlam) simulations were used to obtain the wind climatology data for the study area. The results indicated that offshore wind energy is promising for expanding the national electricity generation and will continue to be a stable resource for electricity generation in the region over the 21st century.

    Climate warming causes the advancement of spring arrival of many migrant birds breeding in Europe, but the effects on their autumn migration are less known. We aimed to determine any changes in the timing of Song Thrush captured during spring and autumn migrations at the Polish Baltic coast from 1975 to 2014, and if these were related to long-term changes of temperature at their breeding grounds and migration routes. The timing of spring migration at Hel ringing station in 1975-2014 did not show long-term advance, but they had responded to environmental conditions on the year-to-year basis. The warmer the temperatures were in April on their migration route, the earlier were the dates of the median and the end of spring migration at Hel. The beginning of autumn migration at the Mierzeja Wiślana ringing station advanced by 5 days between 1975 and 2014. The warmer the April on route, and the July at the Song Thrushes' breeding grounds, the earlier young birds began autumn migration across the Baltic coast. We suggest this was a combined effect of adults' migration and breeding early during warm springs and young birds getting ready faster for autumn migration during warm summers. The average time span of 90% of the autumn migration was extended by 5 days, probably because of early migration of young birds from first broods and late of those from second broods enabled by warm springs and summers. The response of Song Thrushes' migration timing to temperatures on route and at the breeding grounds indicated high plasticity in the species and suggested it might adapt well to climate changes.

    Full Text Available Two new species of marine Platyhelminthes, Microstomum laurae sp. nov. and Microstomum edmondi sp. nov. (Macrostomida: Microstomidae are described from the west coast of Sweden. Microstomum laurae sp. nov. is distinguished by the following combination of characters: rounded anterior and posterior ends; presence of approximately 20 adhesive papillae on the posterior rim; paired lateral red eyespots located level with the brain; preoral gut extending anterior to brain and very small sensory pits. Microstomum edmondi sp. nov. is a protandrous hermaphrodite with a single ovary, single testis and male copulatory organ with stylet. It is characterized by a conical pointed anterior end, a blunt posterior end with numerous adhesive papillae along the rim, and large ciliary pits. The stylet is shaped as a narrow funnel with a short, arched tip. In addition, the first records of fully mature specimens of Microstomum rubromaculatum von Graff, 1882 from Fiskebäckskil and a phylogenetic analysis of Microstomum Schmidt, 1848 based on the mitochondrial cytochrome oxidase I (COI gene are presented.

    The pathology and morphology of Ichthyophonus hoferi was studied in naturally infected Atlantic herring Clupea harengus, in sprat Sprattus sprattus, and in flounder Pleuronectes flesus from the west coast of Sweden. The pathogen was found in all organs examined, with the intensity of infection varying in different organs of the different fish species. Two main phases in the life of infecting parasites were identified, 'active' and 'passive', the latter being able to switch to active. The active phase of the infection in herring was usually accompanied by a lean and slender appearance of the body, a drastic decrease in intestinal fat, emaciation of the somatic muscles, swelling of the visceral organs, poor quality of flesh texture and a distinctive off-odour. The most characteristic macroscopic sign of ichthyophonosis in herring and flounder was the occurrence of creamy white nodules on the heart. The infection causes a chronic systemic granulomatous inflammation. The nature of the granulomatous inflammation was host- and tissue-dependent. The pathogenicity of the parasite in its active form and the side effects of host defence cells were also reflected in dramatic tissue damage and loss of structure and function of the infected organs. Three kinds of spores were identified: 'un-developing spore', 'developing spore' and 'plasmodio-spore'. The formation and spread of 'plasmodia', from plasmodio-spores, as a secondary infection agent is documented. Transmission electron microscopy revealed I. hoferi to be multinucleated, containing different organelles and structures. These included a cell wall, an undulating cell membrane, a thin paramural endoplasm, an endoplasmic reticulum, polymorphic but usually spherical mitochondria with short tubulo-vesicular cristae, dictyosomes with plate-like cristernae, large electron-dense lipid droplets and electron-lucid vacuoles, probably containing glycogen.

  19. Abundance and size distribution of the sacoglossan Elysia viridis on co-occurring algal hosts on the Swedish west coast.

    Directory of Open Access Journals (Sweden)

    Finn A Baumgartner

    Full Text Available Sacoglossans are specialized marine herbivores that tend to have a close evolutionary relationship with their macroalgal hosts, but the widely distributed species Elysia viridis can associate with several algal species. However, most previous investigations on the field abundance and size distribution of E. viridis have focussed on Codium spp. in the British Isles, and algae from this genus are considered superior hosts for E. viridis. In the present study, we investigated the abundance and size distribution of E. viridis on 6 potential host algae with differing morphologies (the septate species Cladophora sericea, Cladophora rupestris, Chaetomorpha melagonium, and Ceramium virgatum, as well as the siphonaceous species Codium fragile and Bryopsis sp. at 2 sites on the Swedish west coast over the course of a year. In spring, slugs were almost absent from all algal hosts. In summer and autumn, E. viridis consistently occurred on several of the algal species at both sites. The highest number of small E. viridis were found on C. sericea, intermediate numbers of significantly larger E. viridis were found on C. rupestris, while fewer, intermediate sized animals were found on C. fragile. Throughout the study period, only a few E. viridis individuals were found on C. melagonium, Bryopsis sp., and C. virgatum. Our results indicate that E. viridis is an annual species in Sweden, capable of exploiting co-occurring congeneric and intergeneric algal hosts with differing morphologies. These results corroborate previous findings that E. viridis can exploit several different algal species, but does not indicate that C. fragile is a superior host.

    preferentially desorbed from the aqueous solution. The changes in the stream composition lead to the formation of iron(oxyhyr)oxide precipitates in the stream bed before the waters pass to underground drainage into a subterranean mixing zone with brackish BS waters. These ochrous precipitates act as a sink for dissolved phosphate and minor calcium. P : Fe ratios and Ca : Fe ratios are about 0.08 and 0.2, respectively, which are caused by P adsorption and a mixture with minor CaCO3 and/or Ca-phosphate. The investigation reveals that the surface precipitation on the beach leads to the formation of SGD essentially free of dissolved iron and strongly depleted in phosphate. Similar iron phases may also be an important part of the subterranean estuary supposed at that coast line, where retention of nutrients and heavy metals by iron(oxyhydr)oxides could influence the release of nutrients into the coastal ecosystem. Fe- and P-rich surface precipitates, however, are transported in suspension into the Baltic Sea during wind-driven flood events.

    Sediment samples from the Baltic basin were analyzed for PCDD/Fs, alkyl-CDFs, chloroguaiacols and EOCl. The EOCl distribution pattern in the Iggesund pulp-mill area shows high sediment concentrations close to the mill, and decreasing concentrations with increasing distance from the mill. Two series of alkyl-CDFs have been identified. The PCDD/Fs in offshore surficial sediments from the Baltic proper show a typical incineration pattern, while sediments collected in the vicinity of the mill show enhanced levels of 2,3,7,8-tetraCDD, 2,3,7,8- and 1,2,7,8-tetraCDF, and 1,2,3,7,8-pentaCDD. These PCDD/F congeners are statistically correlated to di-, tri-, and tetrachloroguaiacols, alkyl-CDFs, EOCl, and to the distance from the pulp mill, indicating the same source and transportation regime. Principal component analysis of the data set supports this conclusion. The three 2,3,7,8-tetrachloro-substituted PCDD/F congeners have formerly been found in high concentrations in sediments and crab hepatopancreas close to a pulp mill on the Swedish west coast. Our results from a pulp mill on the Swedish east coast support the conclusion that these congeners are typically associated with pulp bleaching. Deep layer sediments have significantly lower levels of PCDD/Fs. The isomer profiles are different in the surficial and the deep sediments, indicating a more natural preindustrial production of PCDD/Fs. (53 refs., 7 figs.).

  4. Coastal Dunes of the Baltic Sea Shores: A Review

    Łabuz Tomasz Arkadiusz

    2018-03-01

    Full Text Available The article summarises results of studies conducted along the Baltic Sea sandy coasts by scientists involved in coastal dune research, and presents an attempt to describe the types and distribution of dune coasts. The Baltic Sea coasts feature lower and higher foredunes. The lowland behind the coastal dune belt is covered by wandering or stabilised inland dunes – transgressive forms, mainly parabolic or barchans. The source of sediment for dune development includes fluvioglacial sands from eroded coasts, river-discharged sand, and older eroded dunes. Due to the ongoing erosion and coastal retreat, many dunes have been eroded, and some are withdrawing onto the adjacent land. There are visible differences between the south-eastern, western, and northern parts of the Baltic Sea coast with respect to dune development. The entire southern and eastern coast abounds in sand, so the coastal dunes are large, formerly or currently wandering formations. The only shifting dunes are found at the Polish and the Russian–Lithuanian coasts on the Łebsko Lake Sandbar as well as on the Vistula and Curonian Spits. The very diverse shoreline of the south-western coast experiences a scarcity of larger sandy formations. Substantial parts of the Baltic Sea sandy coasts have been eroded or transformed by humans. The northern part of the Baltic Sea coast features mainly narrow and low sandy coasts (e.g. in Estonia. Further north, sandy dunes are virtually absent.

    Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyl (dl-PCBs) concentrations in Baltic herring (Clupea harengus) have been relatively stable since the mid to late 1990s. It is unclear why concentrations in Baltic herring are not following the observed decreases in other environmental matrices. Here, changes in long-term temporal trends in Baltic herring were examined. A number of biological variables were examined alongside the temporal trends to investigate whether fish biology e.g., growth (length, weight, age), lipid content, reproductive phase or fishing date may provide an explanation for the temporal trends observed. Significant (p<0.05) decreasing trends were observed for PCDD/F toxic equivalents (TEQPCDD/F) at three of the four sites (lipid weight (lw) and wet weight (ww), Swedish west coast lw only); however, other TEQ values e.g., TEQPCDD, TEQPCDF, TEQdl-PCB, TEQPCDD/F+dl-PCB were inconsistent, decreasing at some sites but not others. In the most recent 10 years of data, fewer significant decreases were seen overall. Over the examined time period, significant decreases (Bothnian Bay, p<0.01, southern Baltic Proper, p<0.02) and increases (Swedish west coast, p<0.02) in lipid content, growth dilution or lack thereof, and significant changes in age were observed. However herring were not randomly selected which biases this result. Continual efforts to decrease PCDD/F and dl-PCB emissions and to locate/reduce hotspots are necessary, while bearing in mind that herring biology may be impeding faster decreases of these chemicals.

  6. Introduction for the SI "Understanding the Baltic Sea"

    The Baltic Sea is a semi-enclosed sea with a low salinity, slow water exchange and distinguished stratification. Natural properties of the Baltic thus promote development of anoxic areas at the deepest parts of the sea. In addition, the coasts of the Baltic Sea are heavily populated - 85 million inhabitants living in the drainage basin and 9 countries surrounding the sea, most of them highly industrially developed. Anthropogenic activities consequently add considerable pressure on the already vulnerable environment of the sea. Eutrophication, over-fishing and changed food-web, oil pollution, occurrence of hazardous substances, damage of seafloor by trawling and construction works are all present in the Baltic Sea.

    Cyst beds in ships and ports in Finland have previously been unstudied. Therefore, sediments from ships' ballast water tanks and four Finnish ports were sampled for dinoflagellate cysts and other phytoplankton. Untreated sediments were incubated at 10 {sup o}C and 20 {sup o}C in the local 6 psu salinity for 1, 4 and 7 days, and vegetative cells were examined with light and scanning electron microscope. Sediments were inhabited by various dinoflagellates, diatoms, chlorophytes, cyanophytes and small flagellates. Germinated dinoflagellates were found in 90% of ballast tanks and in all ports. Gymnodiniales spp. and Heterocapsa rotundata formed a major proportion of the proliferating dinoflagellate cells. One species, Peridinium quinquecorne, not previously reported from the Baltic Sea, was identified with SEM. The study emphasises that ships are potential transport vehicles for dinoflagellate cysts even in the low salinity Finnish waters, and small-sized dinoflagellates should be focused upon in ballast water studies.

  9. Regional decision-makers as potential users of Extreme Weather Event Attribution - Case studies from the German Baltic Sea coast and the Greater Paris area

    Full Text Available Extreme Event Attribution has raised increasing attention in climate science in the last years. It means to judge the extent to which certain weather-related extreme events have changed due to human influences on climate with probabilistic statements. Extreme Event Attribution is often anticipated to spur more than just scientific ambition. It is able to provide answers to a commonly asked questions after extreme events, namely, ‘can we blame it on climate change’ and is assumed to support decision-making of various actors engaged in climate change mitigation and adaptation. More in-depth research is widely lacking about who these actors are; in which context they can make use of it; and what requirements they have, to be able to actually apply Extreme Event Attribution. We have therefore addressed these questions with two empirical case studies looking at regional decision-makers who deal with storm surge risks in the German Baltic Sea region and heat waves in the Greater Paris area. Stakeholder interviews and workshops reveal that fields of application and requirements are diverse, difficult to explicitly identify, and often clearly associated with stakeholders' specific mandate, the hazard background, and the regional socio-economic setting. Among the considered stakeholders in the Baltic Sea region, Extreme Event Attribution is perceived to be most useful to awareness-raising, in particular for climate change mitigation. They emphasised the importance of receiving understandable information - and that, rather later, but with smaller uncertainties than faster, but with higher uncertainties. In the Paris case, we typically talked to people engaged in adaptation with expertise in terms of climate science, but narrowly defined mandates which is typical for the Paris-centred political system with highly specialised public experts. The interviewees claimed that Extreme Event Attribution is most useful to political leverage and public

  11. Baltic Eye: Focusing on Science and Communication to Improve Policy Making for the Baltic Sea Environment

    2016-12-01

    In order to better communicate relevant scientific knowledge to policy- and decision makers, Stockholm University and the Baltic Sea 2020 Foundation partnered to create Baltic Eye in 2014. Seven scientists and two communicators constitute the core team of this initiative. The team integrates communications with scientific analysis and synthesis of Baltic Sea environmental issues. In the past year, the team has focused on two main issues: fisheries management and microplastics. Baltic Sea cod stocks are in poor condition, with large numbers of small individuals. Baltic Eye recommended improvements to the European Union's multiannual fisheries plan to better align with ecosystem-based management principles: prioritization of cod stock recovery, greater consideration of natural variability of temperature and salinity (which affects cod spawning success), and inclusion of mechanisms to adjust quotas in the event of major environmental changes. Communications included policy briefs and debate articles targeted to the European Parliament, national government ministries, and non-governmental organizations. Every year, up to 40 tons of microplastics from personal care products are released in the Baltic Sea catchment. Baltic Eye raised awareness of the issue and made recommended ways to reduce microplastic emissions. Communications included a public presentation to journalists, politicians, and representatives of Swedish government ministries. A policy brief was provided Heads of Delegates of the Helsinki Commission (for protrection of the Baltic Sea environment) in advance of a meeting to develop a plan of action for marine litter. Researchers were interviewed for radio, TV, and print media in Sweden, Finland, and Germany. Next steps are to engage with multinational manufacturers about plans to voluntarily phase out microplastics in personal care products.

    The biliary trematode Pseudamphistomum truncatum parasitizes a wide range of fish-eating mammals, including humans. Here we report the emergence of this parasite in grey seals (Halichoerus grypus) in the Baltic Sea. One hundred eighty-three of 1 554 grey seals (11.9%) examined from 2002–2013 had detectable hepatobiliary trematode infection. Parasite identification was confirmed as P. truncatum by sequencing the ITS2 region of a pool of five to 10 trematodes from each of ten seals collected off the coast of seven different Swedish counties. The proportion of seals parasitized by P. truncatum increased significantly over time and with increasing age of seals. Males were 3.1 times more likely to be parasitized than females and animals killed in fishery interactions were less likely to be parasitized than animals found dead or hunted. There was no significant difference in parasitism of seals examined from the Gulf of Bothnia versus those examined from the Baltic Proper. Although the majority of infections were mild, P. truncatum can cause severe hepatobiliary disease and resulted in liver failure in at least one seal. Because cyprinid fish are the second intermediate host for opisthorchiid trematodes, diets of grey seals from the Baltic Sea were analysed regarding presence of cyprinids. The proportion of gastrointestinal tracts containing cyprinid remains was ten times higher in seals examined from 2008 to 2013 (12.2%) than those examined from 2002 to 2007 (1.2%) and coincided with a general increase of trematode parasitism in the host population. The emergence and relatively common occurrence of P. truncatum in grey seals signals the presence of this parasite in the Baltic Sea ecosystem and demonstrates how aquatic mammals can serve as excellent sentinels of marine ecosystem change. Investigation of drivers behind P. truncatum emergence and infection risk for other mammals, including humans, is highly warranted. PMID:27755567

    All four Swedish nuclear power plants (Forsmark, Oskarshamn, Barsebaeck and Ringhals) use brackish water as coolant (Baltic Sea and Swedish west coast). Radionuclides are discharged together with the cooling water. The gamma spectra of monthly algal samples harvested in 1992 and 1993 close to the discharge points of these power plants were determined within the routine monitoring programmes. The main radionuclides detected in the algal samples were {sup 54}Mn, {sup 58}Co, {sup 60}Co and {sup 137}Cs. Most {sup 137}Cs in the samples from the northern Baltic Sea (Forsmark) still originated from the 1986 Chernobyl accident. Other radionuclides, notably {sup 51}Cr, {sup 65}Zn, {sup 95}Zr, {sup 95}Nb, {sup 110m}Ag, {sup 124}b, {sup 125}Sb and {sup 134}Cs, were regularly detected at s of the sites. Transfer factors from discharge to algae were generally in the order of 0.3-3 Bq kg{sup -1} per MBq discharge. For the major discharged radionuclides, significant linear relationships were in most cases found between discharges and concentrations in algal samples. Differences in transfer factors and regression coefficients were explained by location of the sampling sites and type of radionuclide. It is concluded that algal samples provide useful complements to water and sediment samples in the monitoring programmes since radionuclide concentrations are much higher in algal samples and proportional to the discharges. 21 refs, figs.

    Full Text Available The western Indo-European vocabulary in Baltic and Slavic is the result of an Indo-European substratum which contained an older non-Indo-European layer and was part of the Corded Ware horizon. The numbers show that a considerable part of the vocabulary was borrowed after the split between Baltic and Slavic, which came about when their speakers moved westwards north and south of the Pripet marshes. Germanic and Balto-Slavic were never contiguous Indo-European dialects at any stage of their prehistory.

  4. The Baltic Klint beneath the central Baltic Sea and its comparison with the North Estonian Klint

    Along its contact with the Baltic Shield, the margin of the East European Platform reveals a well-developed, flooded terraced relief. The most striking and consistent set of escarpments at the contact of the Lower Palaeozoic calcareous and terrigenous rocks, known as the Baltic Klint (BK), extends from northwest of Russia to the Swedish island of Öland. Marine seismic reflection profiling in 1990-2004 revealed the central Baltic Sea Klint (BSK) section in detail and enabled comparison of its geology/geomorphology with a classical klint-section onshore, namely the North Estonian Klint (NEK). The conception of the BK onshore, which is based on the land-sea separating terraced relief in northern Estonia, is not fully applicable beneath the sea. Therefore, we consider that the BSK includes the entire terraced Cambrian outcrop. We suggest the term "Baltic Klint Complex" to include the well-terraced margin of the Ordovician limestone outcrop, which is weakly developed in Estonia. Because of a steady lithological framework of the bedrock layers across the southern slope of the Fennoscandian Shield, the central BSK in the western and the NEK in the eastern part of the Baltic Homocline have largely identical morphologies. The North Estonian Ordovician limestone plateau with the calcareous crest of the BK extends across the central Baltic Sea, whereas morphological changes/variations along the Klint base occur due to the east-westerly lithostratigraphic/thickness changes in the siliciclastic Cambrian sequence. The verge of the NEK, located some 30-50 m above sea level, starts to drop in altitude as its east-westerly course turns to northeast-southwest in western Estonia. Further westwards, the BK shifts gradually into southerly deepening (0.1-0.2°) layers as its crest drops to c. 150 m below sea level (b.s.l.) near Gotska Sandön. This course change is accompanied by a considerable decrease in thickness of the platform sedimentary cover, as below the central Baltic Sea the

    The aim of this study was to explore: (1) how the psychological health of the members of the first European Union Naval Force (ME01) was affected by international deployment off the coast of Somalia; and (2) if and how organizational and personal factors (e.g., type of personnel category, previous experiences, and resilience) affected their psychological health and well-being post-deployment. The study had an exploratory longitudinal design, where the participants were assessed both before and after deployment (i.e., T1 and T2). The participants (n = 129, 120 men, 9 women) were equally distributed between officers (n = 68; 64 men, 4 women) and sailors (n = 61; 56 men, 5 women). The members' average age was 31 years, ranging from 20 to 61. For the majority (78%) ME01 was their first international deployment and officers were, in general, more experienced than sailors. The overall results showed that the members' reported a positive experience with improved resilience and well-being (e.g., sense of coherence). However, the result also showed that type of personnel category (i.e., officer or sailor) affected their psychological health. Why and how these differences among military personnel arise is discussed, but deserves further attention. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available Mercury is a toxic pollutant emitted from both natural sources and through human activities. A global interest in atmospheric mercury has risen ever since the discovery of the Minamata disease in 1956. Properties of gaseous elemental mercury enable long range transport, which can cause pollution even in pristine environments. Gaseous elemental mercury (GEM was measured from winter 2016 to spring 2017 over the Baltic Sea. A Tekran 2357A mercury analyser was installed aboard the research and icebreaking vessel Oden for the purpose of continuous measurements of gaseous mercury in ambient air. Measurements were performed during a campaign along the Swedish east coast and in the Bothnian Bay near Lulea during the icebreaking season. Data was evaluated from Gothenburg using plotting software, and back trajectories for air masses were calculated. The GEM average of 1.36 ± 0.054 ng/m3 during winter and 1.29 ± 0.140 ng/m3 during spring was calculated as well as a total average of 1.36 ± 0.16 ng/m3. Back trajectories showed a possible correlation of anthropogenic sources elevating the mercury background level in some areas. There were also indications of depleted air, i.e., air with lower concentrations than average, being transported from the Arctic to northern Sweden, resulting in a drop in GEM levels.

  8. Future conditions for integration of the Baltic Electricity Supply System

    International Nuclear Information System (INIS)

    1999-01-01

    The economies of Estonia, Latvia and Lithuania developed in close association with the north-west region of the former Soviet Union. This is especially true for energy supply systems and electricity generation and transmission; the Baltic States depend on Russia for much of their primary energy needs, and export power to Russia and Belarus. In restructuring their electricity industries, the Baltic States hope to establish closer relationships and trade with Western Europe. The initial focus has been on changes to the legislative framework, industry restructuring and the establishment of new regulatory institutions. Vertically integrated utilities are in the process of being broken up into a number of separate generation, transmission and distribution companies. This restructuring is a prelude to privatisation. The states aim to establish a common power market among themselves, and hope to integrate this market with neighbouring (Nordic and European) markets. Despite the target set by the Baltic authorities of a common market by 2001, there is little clarity, as yet, on the framework and guidelines for the structure and functioning of the market. This process is supported by other players in the region, and the EU has recently prioritised closer co-operation and harmonisation of power networks in the Baltic Sea region. The Swedish National Energy Administration has identified cooperation on energy and environmental issues in the Baltic Sea region as one of its priorities. Consequently, the Administration commissioned ECON to analyse the conditions for closer linkages between the Baltic and Nordic electricity systems. This report presents the findings of this analysis

    The Baltic Sea region, defined as its river catchment basin, spans different climate and population zones, from a temperate, highly populated, industrialized south with intensive agriculture to a boreal, rural north. It encompasses most of the Scandinavian Peninsula in the west; most of Finland and parts of Russia, Belarus, and the Baltic states in the east; and Poland and small parts of Germany and Denmark in the south. The region represents an old cultural landscape, and the Baltic Sea itself is among the most studied sea areas of the world. Baltic Earth is the new Earth system research network for the Baltic Sea region. It is the successor to BALTEX, which was terminated in June 2013 after 20 years and two successful phases. Baltic Earth stands for the vision to achieve an improved Earth system understanding of the Baltic Sea region. This means that the research disciplines of BALTEX continue to be relevant, i.e. atmospheric and climate sciences, hydrology, oceanography and biogeochemistry, but a more holistic view of the Earth system encompassing processes in the atmosphere, on land and in the sea as well as in the anthroposphere shall gain in importance in Baltic Earth. Specific grand research challenges have been formulated, representing interdisciplinary research questions to be tackled in the coming years. A major means will be scientific assessments of particular research topics by expert groups, similar to the BACC approach, which shall help to identify knowledge gaps and develop research strategies. Preliminary grand challenges and topics for which Working Groups have been installed include: • Salinity dynamics in the Baltic Sea • Land-Sea biogeochemical feedbacks in the Baltic Sea region • Natural hazards and extreme events in the Baltic Sea region • Understanding sea level dynamics in the Baltic Sea • Understanding regional variability of water and energy exchange • Utility of Regional Climate Models • Assessment of Scenario Simulations

    Bis(4-chlorophenyl) sulfone (BCPS) is a high production volume chemical (HPVC) applied in thermostable polymers. BCPS has been detected as an environmental contaminant both in Europe and in North America but it is still not a commonly studied pollutant. In this study, three Baltic Sea fish species; herring (Clupea harengus), salmon (Salmo salar) and perch (Perca fluviatilis) from the Swedish coast, and one inland fish species, arctic char (Salvelinus alpinus), were analysed to screen for the occurrence and distribution of BCPS. Salmon and arctic char, were sampled in the early 1970s as well as the late 1990s. Fish eating grey seal (Halichoerus gryphus) and guillemot (Uria aalge) from the Baltic Sea were included to screen for whether BCPS biomagnify or not. The representativeness of the analysed samples for studying bioaccumulation of environmental pollutants was compared through analysis of two well known persistent and bioaccumulating compounds, 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153), and 4,4'-DDE. Pooled muscle and blubber samples based on 4-10 individuals were used for analysis, as well as individual samples of grey seal blubber. 2,4,4'-Trichlorodiphenyl sulfone, was synthesised and applied as an internal standard. BCPS was detected in all marine samples but in only one of the fresh water fish samples. The highest BCPS concentrations detected, 1600 and 1900 ng/g lipid weighet (l.w.), were found in muscle from Baltic guillemot. The results indicate that BCPS is bioaccumulated in both grey seal and guillemot, and that the guillemot has higher concentrations of BCPS than the grey seal (50-500 ng/g l.w.). The concentrations found in different species of fish from the Baltic Sea ranged between 15-37 ng/g l.w. and lower concentrations were found in freshwater species (n.d.-1.8 ng/g l.w.). The present study shows that BCPS is found in all investigated species of wildlife but, in most species, still at low concentrations. However, the guillemot has levels in the

  16. Ensemble-based evaluation of extreme water levels for the eastern Baltic Sea

    2016-04-01

    The risks and damages associated with coastal flooding that are naturally associated with an increase in the magnitude of extreme storm surges are one of the largest concerns of countries with extensive low-lying nearshore areas. The relevant risks are even more contrast for semi-enclosed water bodies such as the Baltic Sea where subtidal (weekly-scale) variations in the water volume of the sea substantially contribute to the water level and lead to large spreading of projections of future extreme water levels. We explore the options for using large ensembles of projections to more reliably evaluate return periods of extreme water levels. Single projections of the ensemble are constructed by means of fitting several sets of block maxima with various extreme value distributions. The ensemble is based on two simulated data sets produced in the Swedish Meteorological and Hydrological Institute. A hindcast by the Rossby Centre Ocean model is sampled with a resolution of 6 h and a similar hindcast by the circulation model NEMO with a resolution of 1 h. As the annual maxima of water levels in the Baltic Sea are not always uncorrelated, we employ maxima for calendar years and for stormy seasons. As the shape parameter of the Generalised Extreme Value distribution changes its sign and substantially varies in magnitude along the eastern coast of the Baltic Sea, the use of a single distribution for the entire coast is inappropriate. The ensemble involves projections based on the Generalised Extreme Value, Gumbel and Weibull distributions. The parameters of these distributions are evaluated using three different ways: maximum likelihood method and method of moments based on both biased and unbiased estimates. The total number of projections in the ensemble is 40. As some of the resulting estimates contain limited additional information, the members of pairs of projections that are highly correlated are assigned weights 0.6.

    Archaeological findings and historical records indicate frequent migrations and exchange of genetic material between populations in the Baltic Sea area. However, there have so far been very few attempts to trace migrations in this area using genetic markers. We have studied the Baltic populations with respect to exceptional variations in the frequencies of the Landsteiner-Wiener (LW) blood group. The frequency of the uncommon LWb gene was high in the Balts, around 6% among Latvians and Lithuanians, very low among the other western Europeans (0-0.1%) and apparently absent in Asiatic and African populations. From the Baltic region of peak frequency there was a regular decline of LWb incidence (a descending cline) in the neighboring populations: 4.0% in the Estonians, 2.9% in the Finns, 2. 2% in the Vologda Russians, and 2.0% in the Poles. Thus the distribution of LWb suggests considerable and extensive Baltic admixture, especially in the north and northeast direction. In Southern Sweden with an LWb frequency of 0.3%, the Baltic influence appeared slight, while in the population of the Swedish island Gotland in the middle of the Baltic Sea there was a significantly increased LWb frequency of 1.0% compared with that of Western European countries. The distinction of codominantly inherited LW antigenic forms, LWa and LWb (previously Nea), is known to be due to a single base substitution. Based on our population data, it is plausible that the expansion of this point mutation occurred only once during human history. Furthermore, our data indicate that the expansion of the LWb mutation occurred in Balts and that LWb can be considered a 'Baltic tribal marker', its presence in other populations being an indicator of the degree of Baltic genetic influence.

    The Authors discuss the Baltic energy policy with respect to new nuclear power plants for Lithuania, Belarus and the Kaliningrad region. The construction of a new nuclear power plant in Lithuania would threaten Russian interests in the region. Therefore Lithuania is looking to Russian plans to build a new nuclear power plant in the Kaliningrad region as an attempt to subvert Lithuania's foreign partners and potential investors from participating in the Visaginas NPP project. However, the authors conclude, that the Visaginas NPP project is and must be the preferential project for the EU and NATO member states.

    We report the first description of a new Rhabdoviridae tentatively named eelpout rhabdovirus (EpRV genus Perhabdovirus). This virus was associated with mass mortalities in eelpout (Zoarces viviparous, Linnaeus) along the Swedish Baltic Sea coast line in 2014. Diseased fish showed signs of central nervous system infection, and brain lesions were confirmed by histology. A cytopathogenic effect was observed in cell culture, but ELISAs for the epizootic piscine viral haemorrhagic septicaemia virus (VHSV), infectious pancreas necrosis virus (IPNV), infectious haematopoietic necrosis virus (IHNV) and spring viraemia of carp virus (SVCV) were negative. Further investigations by chloroform inactivation, indirect fluorescence antibody test and electron microscopy indicated the presence of a rhabdovirus. By deep sequencing of original tissue suspension and infected cell culture supernatant, the full viral genome was assembled and we confirmed the presence of a rhabdovirus with 59.5% nucleotide similarity to the closest relative Siniperca chuatsi rhabdovirus. The full-genome sequence of this new virus, eelpout rhabdovirus (EpRV), has been deposited in GenBank under accession number KR612230. An RT-PCR based on the L-gene sequence confirmed the presence of EpRV in sick/dead eelpout, but the virus was not found in control fish. Additional investigations to characterize the pathogenicity of EpRV are planned. © 2016 John Wiley & Sons Ltd.

    Laboratory studies suggest that the cyclic volatile methylsiloxanes (cVMS) octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5) and dodecamethylcyclohexasiloxane (D6) will persist in the aquatic environment and bioaccumulate in fish. Here these cVMS were measured in herring collected in the Swedish waters of the Baltic Sea and the North Sea and in grey seals from the Baltic Proper. D4, D5, and D6 were present in herring muscle at concentrations around 10, 200, and 40ngg(-1) lipid weight, respectively. The ratio of these concentrations was similar to the relative magnitude of estimated emissions to water, suggesting that the efficiency of overall transfer through the environment and food web was similar (within a factor 2-3) for the three chemicals. The concentrations of D5 and D6 were similar in herring caught in the highly populated Baltic Proper and in the less populated Bothnian Sea and Bothnian Bay. The D4 concentrations were lower at the most remote northern station, suggesting that D4 is less persistent than D5 and D6. Herring from the North Sea had lower levels of all three chemicals. The concentrations of D4, D5 and D6 in grey seal blubber were lower than the lipid normalized concentrations in herring, indicating that they do not biomagnify in grey seals.

    Temporal trends of five tetra- to hexabromodiphenyl ethers [BDE47, BDE99, BDE100, BDE153 and BDE154) and two methoxy-tetraBDEs [6-methoxy-2,2',4,4'- tetraBDE (6-MeO-BDE47) and 2'-methoxy-2,3',4,5'- tetraBDE (2'-MeO-BDE68)] in pike from Lake Bolmen for the years 1967-2000, are presented. All BDE congeners show increasing trends up to the mid-1980s ({sigma}5PBDE from 60 to 1600 pg/g wet weight in 1989, i.e. a more than 25-fold increase), and then decrease or level off. The decreasing trends of PBDEs after the 1980s were considerably slower in the present study than was found in a study of an environmental matrix from the Baltic Proper covering the same time period. This difference suggests local sources near Lake Bolmen. The MeO-BDEs show initially decreasing concentrations, which for 6-MeO-BDE47 continues until the early 1990s. The concentrations of 6-MeO-BDE47 in herring from five locations along the Swedish coast increased from south to north in the Baltic Sea. No correlation between the concentrations of the BDE congeners and the MeO-BDEs was observed, indicating sources other than PBDEs for these compounds. The presence of MeO-BDEs in fish from lakes with different characteristics suggests a natural production not favoured by eutrophication, or dependent on sampling season and geographical location. - PBDEs and MeO-BDEs show different temporal trends in pike from a Swedish lake suggesting different sources.

  8. Emission Permits trade between the Nordic and Baltic Countries

    Energy Technology Data Exchange (ETDEWEB)

    Alm, Leif Kristian

    2000-05-01

    A bottom-up technology oriented model of the energy systems in the Nordic and Baltic countries have been constructed and used for analysing an optimal set of energy and emission trading within the region. The model used is MARKAL, which has been developed within the IEA-ETSAP. The analyses are based on national emission levels agreed on in the Kyoto protocol (and the following burden sharing negotiations within the European Union), and with an additional strengthening after 2010. Only energy related CO{sub 2} emissions are explicitly considered. Nuclear power in Sweden is assumed to be phased out. The results show that especially Norway and Sweden have large abatement costs when acting alone, whale the Baltic countries will probably not need to take domestic actions due to the Kyoto protocol if they act alone, as the restructuring of their economies in the beginning of the 1990ties cut emissions (and their economies) dramatically. It is shown that emission trading among the Nordic and Baltic countries can reduce abatement costs among the Nordic countries significantly, possibly down to a level equivalent to a world market (Annex I) permit price. Extending the Nordic common electricity market to Balticum will have minor influence on overall energy system costs. There is no pronounced direction for net electricity flow between the Nordic and Baltic countries. High marginal costs during peak hours in Balticum indicate that imports of Nordic hydro power during peak-hours could be a cost-effective option. This possibility could be implemented with a subsea AC/DC connection between Sweden and Latvia. It is politically viable to develop more hydropower in Norway, this country will be the major electricity exporter in the region, while Sweden will be the main importer. Changing scenario assumptions, i.e. no more Norwegian hydropower, but life extension of Swedish nuclear power, could change this picture. (author)

Quantity of macro/meso/microplastic objects in the upper 2cm of the sandy sediments of the wrack zone at 13 sampling sites all along the Russian coast is reported. Occurrence of paraffin and amber pieces at the same sites is pointed out. Special attention is paid to microplastics (range 0.5-5mm): its content ranges between 1.3 and 36.3 items per kg dry sediment. The prevailing found type is foamed plastic. No sound differences in contamination are discovered between beaches with high and low anthropogenic load. Mean level of contamination is of the same order of magnitude as has been reported by other authors for the Baltic Sea beaches. Copyright © 2016 Elsevier Ltd. All rights reserved.

  10. Finnish Archaeologists’ Contacts with the Baltic Countries during the Second World War

    2015-10-01

    Full Text Available Finnish archaeologists, especially Aarne Michaël Tallgren, had established contacts with their colleagues in the Baltic countries before the Second World War. In the summer of 1939, the world situation became a dominant theme in letters between archaeologists. The outbreak of war in Europe and the military base negotiations in Moscow evoked increasing concern. After the Soviet attack on Finland, only a few Finnish and Baltic archaeologists stayed in contact, but communications revived quickly after the Finnish-Soviet peace treaty of 1940. Estonian archaeologist Harri Moora saw the trials of war as a punishment for forgetting all spiritual values in previous years. The Soviet occupation of the Baltic countries in 1940 broke all contacts for longer than a year. After Germany had occupied the Baltic countries in 1941 and was allied with Finland in war against the Soviet Union, connections could be resumed to some extent. Tallgren, together with the Swedish State Antiquarian Sigurd Curman, now started planning the evacuation of children from Estonia to Sweden. In 1942, scholarly discussion returned to the correspondence, although only on a practical level, but already in early 1943 all correspondence became impossible. At the same time, Finnish archaeologists were in contact with Baltic refugees, especially Francis Balodis from Latvia. There were also Scandinavian and British archaeologists with whom Finnish researchers exchanged information about colleagues in the Baltic countries. The communications mainly focused on three things: getting and spreading information regarding the current situation, offering both practical help and psychological support to colleagues in the Baltic countries, and attempting to re-establish the exchange of ideas within the scholarly community.

    Many coastal and offshore fish species are highly dependent on specific habitat types for population maintenance. In the Baltic Sea, shallow productive habitats in the coastal zone such as wetlands, vegetated flads/lagoons and sheltered bays as well as more exposed rocky and sandy areas are utilized by fish across many life history stages including spawning, juvenile development, feeding and migration. Although there is general consensus about the critical importance of these essential fish habitats (EFH) for fish production along the coast, direct quantitative evidence for their specific roles in population growth and maintenance is still scarce. Nevertheless, for some coastal species, indirect evidence exists, and in many cases, sufficient data are also available to carry out further quantitative analyses. As coastal EFH in the Baltic Sea are often found in areas that are highly utilized and valued by humans, they are subjected to many different pressures. While cumulative pressures, such as eutrophication, coastal construction and development, climate change, invasive species and fisheries, impact fish in coastal areas, the conservation coverage for EFH in these areas remains poor. This is mainly due to the fact that historically, fisheries management and nature conservation are not integrated neither in research nor in management in Baltic Sea countries. Setting joint objectives for fisheries management and nature conservation would hence be pivotal for improved protection of EFH in the Baltic Sea. To properly inform management, improvements in the development of monitoring strategies and mapping methodology for EFH are also needed. Stronger international cooperation between Baltic Sea states will facilitate improved management outcomes across ecologically arbitrary boundaries. This is especially important for successful implementation of international agreements and legislative directives such as the Baltic Sea Action Plan, the Marine Strategy Framework

One...... of the results was nutrient reduction targets for each country - the BSAP targets. Because the Baltic Sea is such an international marine area, receiving pollutants from many  countries, an international approach is necessary to make effective solutions. But is the BSAP the most cost-effective solution...... to the regulation of the Baltic Sea? And does the BSAP result in cost-effective reductions in the different countries, which is a requirement of the Water Framework Directive and the Marine Strategy Directive?   These questions are studied and answered using a cost minimisation model for the Baltic sea, initially...

    1997-10-01

    The vegetation and environmental conditions of south Swedish horn-beam Carpinus betulus forests are described with data from 35 permanent sample plots. The main floristic gradient of the ground vegetation is closely related to acid-base properties of the top soil: Base saturation, pH and organic matter content. Other floristic differences are related to tree canopy cover and the distance of the sample plots to the Baltic coast. Species richness of herbaceous plants typical of forests increases with soil pH. The number of other herbaceous species, occurring in both forests and open habitats, and of woody species is not related to pH. Comparisons of vegetation data from 1983 and 1993 show relatively small compositional differences of the herbaceous forest flora. The number of other herbaceous species increased considerably in those plots where canopy trees had been cut after 1983. The number of new species in managed plots increases with soil pH. Species losses and gains of the herbaceous forest flora between 1983 and 1993 are generally lower as compared with other herbaceous species and woody species. However, the ground cover of herbaceous forest species, especially of Oxalis acetosella and Lamium galeobdolon, was considerably lower in 1993 as compared to 1983 in both unmanaged and managed plots. Possible explanations for this decrease are current soil acidification and drought during the growing season. (au) 32 refs.

  18. Construction of transport and energy networks in the Baltic region as an impetus for regional development

    2013-11-01

    Full Text Available In light of some new aspects of the EU functioning, particularly, the recovery from the 2008-2009 global crisis, transportation and energy development projects are coming to the forefront in the Baltic region. At the same time, there is a need to consider EU’s recent adoption of a common seven-year financial program (2014—2020, which serves, in effect, as the Union’s budget. Given that, one may conclude that the countries of the Baltic region are entering a new stage of development. We look at the role and significance of transportation and energy projects as an instrument of economic development. Having studied the largest transport and energy projects in the Baltic region, we were able to show that the new infrastructure networks supported the investment expansion of Swedish and Finnish companies into the post-communist countries of the Baltic Region. Which, in its turn, allowed the Nordic investors to expand their domestic markets. The analysis also shows that the experience of private businesses proves a recent theoretical concept — the pyramid of regional development factors. As a result, the actual regional policy of the EU cannot be considered in the narrow sense of the Cohesion Policy alone.

  19. The undersea location of the Swedish Final Repository for reactor waste, SFR - human intrusion aspects

    1989-01-01

    The Swedish Final Repository for reactor waste, SFR, is built under the Baltic sea close to the Forsmark nuclear power plant. Sixty metres of rock cover the repository caverns under the seabed. The depth of the Baltic sea is about 5-6 m at this location. A human intrusion scenario that in normal inland locations has shown to be of great importance, is a well that is drilled through or in the close vicinity of the repository. Since the land uplift in the SFR area is about 6 mm/year the undersea location of SFR ensures that no well will be drilled at this location for a considerable time while the area is covered by the Baltic sea

    Full Text Available Radiation data recorded at 12 sites around the central part of the Baltic Sea during 1996-2000 drawn from the BALTEX (Baltic Sea Experiment meteorological data archives are used to study the spatio-temporal variability of daily global radiation totals. The annual average daily global radiation total varies from about 10 MJ m-2 at Visby(on Gotland and Kołobrzeg (on the coast of Poland to less than 9 MJ m-2 at Zīlāni (inland Latvia, Šilutė (Lithuaniaand Jokioinen (Finland. The monthly average daily global radiation total over the whole region extends from 0.93 in December to 19.0 in June. The variability in global radiation is analysed on the basis of the fraction of the daily total at the top of the atmosphere.The spatial and temporal variability is the least in August - this shows that the variation in the cloud cover and atmospheric properties at this time of year is the smallest. The spatial correlation is the strongest between the two Finnish stations - Vantaa and Jokioinen. It is also high between Stockholm and Norrköping, on the east coast of Sweden. The correlation coefficients are the largest over the whole area in April. Radiation data from coastal stations are compared with an earlier parameterization basedon ship observations (Rozwadowska & Isemer 1998, Isemer & Rozwadowska 1999. It is concluded that in climatological research, actinometric data from Visby can be used to characterize the radiation field over the northern part of the Baltic Proper and those from Kołobrzeg to characterize the radiation field over the southern part of this sea.

    Temporal trends of five tetra- to hexabromodiphenyl ethers [BDE47, BDE99, BDE100, BDE153 and BDE154) and two methoxy-tetraBDEs [6-methoxy-2,2',4,4'- tetraBDE (6-MeO-BDE47) and 2'-methoxy-2,3',4,5'- tetraBDE (2'-MeO-BDE68)] in pike from Lake Bolmen for the years 1967-2000, are presented. All BDE congeners show increasing trends up to the mid-1980s (Sigma5PBDE from 60 to 1600 pg/g wet weight in 1989, i.e. a more than 25-fold increase), and then decrease or level off. The decreasing trends of PBDEs after the 1980s were considerably slower in the present study than was found in a study of an environmental matrix from the Baltic Proper covering the same time period. This difference suggests local sources near Lake Bolmen. The MeO-BDEs show initially decreasing concentrations, which for 6-MeO-BDE47 continues until the early 1990s. The concentrations of 6-MeO-BDE47 in herring from five locations along the Swedish coast increased from south to north in the Baltic Sea. No correlation between the concentrations of the BDE congeners and the MeO-BDEs was observed, indicating sources other than PBDEs for these compounds. The presence of MeO-BDEs in fish from lakes with different characteristics suggests a natural production not favoured by eutrophication, or dependent on sampling season and geographical location.

    2007-01-01

    Integration of New Member States to the European Union has created a new situation in the frame of implementation of the Lisbon strategy and EU Sustainable Development. The closure of Ignalina NPP is the biggest challenge to the energy sector development of the Baltic States. The Baltic States have quite limited own energy resources and in the Accession agreement with the EU Lithuania, Latvia and Estonia have verified their targets to increase the share of electricity produced from renewable energy sources (RES-E) by the year 2010. A wider use of renewable energy and increase of energy efficiency can make a valuable contribution to meeting the targets of sustainable development. The article presents a detailed overview of the present policies and measures implemented in the Baltic States, aiming to support the use of RES and the increase of energy efficiency. The review of possibilities to use the EU Structural Funds (SF) for the implementation of sustainable energy projects in the Baltic States was performed.The use of regional social-economic-environmental indicators is the main key to integrate sustainable energy development at the program deployment level. The indicators to be used should describe the contribution of energy programs to the sustainable development, medium- and long-term trends and inter-relationship between them and the typical energy indicators (saved toe, improved energy efficiency, percentage of RES). Municipalities may play a considerable role by promoting sustainable energy since local authorities are fulfilling their functions in the energy sector via a number of roles. The Netherlands' example shows that municipalities may act as facilitators by implementing national environmental policy and increasing energy efficiency in an integral part of these activities. The guidelines for Lithuanian local sustainable energy development using the SF co-financing have been presented

Varem mõisteti Baltikumi all laiemat ala, kuhu kuulusid ka Poola ja Soome. Uurides, kui palju „Balti“ kirjanikke on tõlgitud naaberkeeltesse, selgus, et läti keelde on neid tõlgitud rohkem kui leedu ja eesti keelde. Samuti on eesti autoreid rohkem tõlgitud soome keelde ja leedu autoreid poola keelde. Ilmneb, et Balti kontseptsioon on liiga kitsas, sest relevantne regioon on suurem: soome-eesti ja leedu-poola suhetega võrreldes ei paista eesti-läti-leedu suhe eriti millegagi silma.   The article takes a closer look at the reference guide 300 Baltic Writers (Kalnačs jt 2009 which was published in 2009. The initial (and may-be even provocative question is, whether the concept “Baltic writer” which is introduced here is indeed as clear and senseful as the introduction suggests. In this introduction, some basic problems occur, as can be exemplified through the following quotations: “This reference book presents a hundred of the best-known writers from each of the three Baltic States, starting with the time in the 16th century when the written word first appeared in their national languages, and going on to the twenty-first century (the bibliography goes up to the year 2008. In doing so, it shows the historical and cultural partnerships between the three Baltic countries.” (p. 5 While the first sentence is comprehensible and correct, the second sentence shows a simple logical mistake: one cannot show a unity simply by putting things together. In doing so, one may create a (wishful unity, i.e. postulate it, but one cannot show it. Also one of the following sentences is not convincing, but highly problematic: “For a long time, the writers, poets, playwrights and literary critics of each of these countries have deserved to be introduced to a wider international literary audience as a regional

    Data from the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera were combined to create this cloud-free natural-color mosaic of Scandinavia and the Baltic region. The image extends from 64oN, 0oE in the northwest to 56oN, 32oE in the southeast, and has been draped over a shaded relief Digital Terrain Elevation Model from the United States Geological Survey. It is displayed in an equidistant conic projection.The image area includes southern Norway, Sweden and Finland, northern Denmark, Estonia, Latvia and part of western Russia. Norway's rugged western coastline is deeply indented by fjords. Elongated lakes, formed by glacial erosion and deposition, are characteristic of the entire region, and are particularly dense throughout Finland and Sweden. Numerous islands are present, and a virtually continuous chain of small, scattered islands occur between Sweden and Finland. The northern and eastern waters of the Baltic Sea are almost fresh, since the Baltic receives saltwater only from the narrow and shallow sounds between Denmark and Sweden that connect it to the North Sea. Most of the major cities within the image area are coastal, including St. Petersburg, Stockholm, Helsinki, Riga, and Oslo.The Multi-angle Imaging SpectroRadiometer (MISR) observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude.MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

  11. International biofuel trade - A study of the Swedish import

    International Nuclear Information System (INIS)

    Ericsson, K.; Nilsson, L.J.

    2004-01-01

    Following the development of large-scale use of biomass energy in the EU, international biofuel trade is a plausible scenario and something that is already taking place in Northern Europe. This paper focuses on Swedish biofuel imports, both direct and indirect imports, the latter which derive from the fact that part of the imported pulpwood and timber end up as fuel. The objective is to describe the biomass import flows, the actors involved and analyse the fundamental drivers for the trade flows. The rapid expansion of biomass energy, that has taken place in district heating since the early 1990s in Sweden, has been met partly by imports. The direct biofuel import was estimated to 18 PJ for 2000, which corresponded to 26% of the biofuel supply in district heating. The total indirect biofuel import was estimated to 9 PJ of which 5.5 PJ is consumed in the district heating sector. Sawmill wood chips, decay-damaged stemwood and pellets are imported from Estonia and Latvia, whereas used wood and solid recovered fuels are imported from Germany and the Netherlands. Tall oil and pellets are imported from North America. Key factors related to the Swedish biofuel import are analysed, both from the view of Swedish demand and from the view of supply in the Baltic countries as well as supply from Germany or the Netherlands. National differences in energy policy are perhaps the most important driving force behind the seemingly strange trade flows. Structures in the different national energy systems are also discussed as well as the transformation process that has taken place in the forest sector in the Baltic countries. (author)

    Aquatic community structure and dynamics are generally controlled by a variety of biological and physical factors. Among these factors in marine ecosystems, salinity is known to have a significant effect on species occurrence and composition. In this study, we investigated the large-scale distribution and abundance of encrusting fauna along a salinity gradient on the shallow Baltic Sea rocky coast. Rock samples collected from 14 locations distributed between the Gulf of Bothnia (salinity 0.6) and Skagerrak (salinity 28) supported a total number of 24 encrusting species. The faunas were composed mostly of marine species with opportunistic life histories; however, some brackish water specialists were also present. The number of species and abundance counts is strongly positively correlated with increases in salinity. No encrusting faunas were recorded below salinity level 4. Multivariate analysis (nMDS) revealed three major groups based on species composition that differed in terms of abundance and number of species. Each group was associated with specific salinity conditions. The first assemblage type occurred within salinity 4-7, the second within salinity between 22 and 27, and the third type was a mixture between the two observed at a salinity of approximately 17. This study indicates that to determine the assemblage structure of the Baltic Sea encrusting fauna, analyses at the family level were found to be a reliable surrogate for species composition.

    2001-08-01

    Long-term information on possible changes in cyanobacterial blooms in the Baltic Sea, formed mainly by Nodularia spumigena and Aphanizomenon sp., was sought in published records in historical (years 1887-1938) and modern (years 1974-1998) phytoplankton data sets. Old and new sampling methods and fixatives were tested to improve the comparison of data that had been collected and analyzed in different ways. A hundred years ago, plankton was mainly of interest as a source of fish food; eutrophication problems were only locally reported from the coast, mainly in southern haffs and the receiving waters of larger cities. There were few recordings of open-sea blooms before World War II. Abundances of Nodularia spumigena and Aphanizomenon sp. were low in the old material, and 137 summer samples from 1887-1938 showed no peak abundance. High abundances are common in the new material, and the range of the numbers of both taxa has increased markedly relative to the old material. Since the 1960s, cyanobacterial blooms have been common in the open sea in both the Baltic proper and the Gulf of Finland, indicating high availability of nutrients.

    2016-12-01

    Full Text Available The purpose of this paper is to describe water circulation patterns for selected lakes found along the Baltic coast in northern Poland and to determine primary recharge mechanisms or pathways that produce an influx or loss of lake water. A secondary purpose of the paper is to determine the magnitude of recharge for each studied source of water – river water influx, surface runoff from direct catchments, forced influx from polders surrounding lakes, and periodic marine water intrusions from the nearby Baltic Sea. It is also important to determine the magnitude of water outflow from lakes to the sea via existing linkages as well as to compare horizontal influx and outflow data. The study area consisted of five lakes located along the Baltic Sea in northern Poland: Łebsko, Gardno, Bukowo, Kopań, Resko Przymorskie. The main driving force of the studied lakes are large rivers that drain lake catchment areas and periodic brackish water intrusions by the Baltic Sea.

  18. Millennial changes of the Baltic Sea salinity. Studies of the sensitivity of the salinity to climate change

    2004-05-01

    An important question for safety assessments of nuclear waste repositories is the salinity of the Baltic Sea under different conditions. The salinity affects the potential recipient ecosystems, the water turnover along the coast and the hydrology as well as the groundwater chemistry. In this report a model that enables computation of the Baltic Sea salinity for different sea level positions and freshwater supplies is presented. The model is used to compute the salinities in Baltic proper, Bothnian Sea and Bothnian Bay for all combinations of global sea level changes from -10 m to 10 m and freshwater supplies from 0 to 60,000 m 3 /s. The results are presented in a series of graphs that enables the reader to make an assessment of the impact of a given climatic change. The model is also used to compute the decrease of the salinity in Bothnian Sea and Bothnian Bay during the next few millennia due to the postglacial uplift. The results show that modest changes in global sea level, say ±1 m, give a salinity change of the order of 1 psu in southern Baltic proper. Changing the freshwater supply with about 2,000 m 3 /s (approximately 10%) gives a similar salinity change. Further, a sea level drop of about 5 m or an increase of the freshwater supply by a factor of 3 is needed to reduce the salinity in southern Baltic proper below 1 psu. In this limit large parts of the Baltic would be limnic. A 50% decrease of the freshwater supply increase the salinity in the southern Baltic proper by a factor of 2 to some 15 psu, but the effect is even more drastic in Bothnian Sea and Bothnian Bay where the salinity increase to 13 and 10 psu, respectively. A less windy climate might have a significant effect in lowering the Baltic salinity due to a combined effect of lowered mixing in Kattegat and lowered exchange between Kattegat and the Baltic. A windier climate will not have such strong effect since increased mixing does not affect the Baltic as much. Most probably the shoreline

    Full Text Available Wooden groin systems on the southwestern Baltic Sea coast are a traditional and important coastal-protection facility, but have been regularly infested and destroyed by the wood-boring bivalve Teredo navalis since the early 1990s. The occurrence of T. navalis was presumed to be limited mainly by the prevailing low salinities. Recently, a possible range expansion of this invasive species to the more eastern parts of the Baltic Sea has been discussed. T. navalis larval settlement was therefore monitored at the distribution boundary of the species in the Baltic Sea over a period of 4 years. At 7 stations along the prevailing salinity gradient on the Mecklenburg-western Pomeranian coast, larval traps were installed at regular time intervals, while at the same time water temperature and salinity were measured continuously every hour. Correlations between measured abiotic parameters and borehole abundance of T. navalis were tested. For the German Baltic Sea coast, no range expansion of T. navalis was confirmed. The salinity and temperatures at the groin systems varied among the study years, and significant correlations between T. navalis borehole abundance and salinity as well as temperature were found. Higher summer temperatures favor the T. navalis borehole abundance on the Mecklenburg-western Pomeranian coast, and may slightly shift the distribution border of this species toward lower salinities.

  2. Solar radiation in the Baltic Sea

    Full Text Available The influx of solar radiation to the Baltic Sea and its penetration into its waters is described on the basis of selected results of optical and bio-optical studies in the Baltic published by various authors during the past ca 50 years. The variability in the natural irradiance of this sea is illustrated on time scales from short-term fluctuations occurring during a single day to differences in mean monthly values over a period of many years. Data on variability of the proportions between UV, VIS and IR energy in the light reaching the sea surface are also discussed.Long-term monthly mean values of the incident solar radiation flux at the surface of the Baltic Proper are given; they were obtained from meteorological and solar radiation measurements and model approximations. The transmittances of these mean monthly radiation fluxes across the surface of the Baltic are given, as are the typical energyand spectral characteristics of the underwater irradiance, its attenuation with depth in the sea and the associated euphotic zone depths, as well as typical ranges of variability of these characteristics in different Baltic basins. Some of these characteristics are illustrated by typical empirical data. These mean values are not fully representative, however, because with the sole use of classical in situ measurement methods from on board research vessels in the Baltic, it has not been possible to gather a sufficientlyrepresentative set of empirical data that would adequately reflect the variability of the optical characteristics of all the basins of this sea. The article goes on to introduce the statistical model of vertical distributions of chlorophyll a concentration in the Baltic and the bio-optical model of Baltic Case 2 waters, the use of which contribute very significantly to this description of the optical characteristics and will enable this data set to be hugely expanded to include all the Baltic basins.

    Liquid discharges of 99 Tc from the Sellafield nuclear facilities increased largely in the mid 90's. These releases are transported to the Nordic sea areas by the ocean currents. Results of the 99 Tc activities along the Norwegian coastal areas and in the North Sea have been reported but then again, the spreading of 99 Tc into Baltic Sea has not been studied thoroughly. Fucus vesiculosus and seawater samples were collected in the summer 1999 from the Finnish coastal areas for measuring 99 Tc in the Baltic Sea area. A modified analytical method for measuring 99 Tc in the environmental samples was developed at that time. The method based on extraction chromatography and liquid scintillation measurement of 99 Tc. The 99 Tc concentration in the Fucus vesiculosus in the Finnish coast of the Baltic Sea varied from 1.6 to 11.6 Bq/kg (dry weight) being highest at the most northern sampling sites. These values were considerable lower than those in the Danish and Norwegian coasts. The variation in the concentrations observed are probably due to biological factors. The 99 Tc concentration in the Baltic Sea water studied was below 0.2 Bq/m 3 . (author)

    The Convention on the Protection of the Marine Environment of the Baltic Sea Area signed in 1974 in Helsinki is probably the most important environmental agreement consummated in the Baltic Sea region. This article is the first study that explores the history of this agreement, also known as the Helsinki Convention, by using primary archival sources. The principal sources are the archives of the Ministry for Foreign Affairs of Finland. We examine the role of Finland in the process that led to the signing of the Helsinki Convention from the perspective of international politics. The study focuses primarily on Finnish, Swedish, and Soviet state-level parties from the end of the 1960s to 1974. We show that Cold War politics affected in several ways negotiations and contents of the Helsinki Convention. We also argue that the Soviet Union used the emerging international environmental issues as a new tool of power politics.

    Due to the special topographical and hydrological features the seas surrounding Sweden are very sensitive to both natural changes and changes caused by man. The sea area between the North Sea and the Baltic Sea has come into focus during the last few decades due to problems with pollution and its impact on the ecosystems and to overfishing of some commer- cially important species. In order to elucidate the present situation from the Swedish viewpoint, the National Board of Fisheries, the National Environment Protection Board and the County Council of the County Goeteborg and Bohyslaen arranged a Symposium on the Situation in the Sea Area between the North Sea and the Baltic Sea in Goeteborg, 14-16 March, 1983. This volume contains lectures given at that Symposium. In most cases there are English summaries and English translations of texts to figures and tables.

    The brackish Baltic Sea hosts species of various origins and environmental tolerances. These immigrated to the sea 10,000 to 15,000 years ago or have been introduced to the area over the relatively recent history of the system. The Baltic Sea has only one known endemic species. While information on some abiotic parameters extends back as long as five centuries and first quantitative snapshot data on biota (on exploited fish populations) originate generally from the same time, international coordination of research began in the early twentieth century. Continuous, annual Baltic Sea-wide long-term datasets on several organism groups (plankton, benthos, fish) are generally available since the mid-1950s. Based on a variety of available data sources (published papers, reports, grey literature, unpublished data), the Baltic Sea, incl. Kattegat, hosts altogether at least 6,065 species, including at least 1,700 phytoplankton, 442 phytobenthos, at least 1,199 zooplankton, at least 569 meiozoobenthos, 1,476 macrozoobenthos, at least 380 vertebrate parasites, about 200 fish, 3 seal, and 83 bird species. In general, but not in all organism groups, high sub-regional total species richness is associated with elevated salinity. Although in comparison with fully marine areas the Baltic Sea supports fewer species, several facets of the system's diversity remain underexplored to this day, such as micro-organisms, foraminiferans, meiobenthos and parasites. In the future, climate change and its interactions with multiple anthropogenic forcings are likely to have major impacts on the Baltic biodiversity.

    In the Baltic Sea, the mesopredator three-spined stickleback (Gasterosteus aculeatus) spends a large part of its life cycle in the open sea, but reproduces in shallow coastal habitats. In coastal waters, it may occur in high abundances, is a potent predator on eggs and larvae of fish, and has been shown to induce trophic cascades with resulting eutrophication symptoms through regulation of invertebrate grazers. Despite its potential significance for the coastal food web, little is known about its life history and population ecology. This paper provides a description of life history traits, migration patterns and spatiotemporal development of the species in the Baltic Sea during the past decades, and tests the hypothesis that stickleback may have a negative impact on populations of coastal predatory fish. Offshore and coastal data during the last 30 years show that stickleback has increased fourfold in the Bothnian Sea, 45-fold in the Central Baltic Sea and sevenfold in the Southern Baltic Sea. The abundances are similar in the two northern basins, and two orders of magnitude lower in the Southern Baltic Sea. The coastward spawning migration of sticklebacks from offshore areas peaks in early May, with most spawners being two years of age at a mean length of 65 mm. The early juvenile stage is spent at the coast, whereafter sticklebacks perform a seaward feeding migration in early autumn at a size of around 35 mm. A negative spatial relation between the abundance of stickleback and early life stages of perch and pike at coastal spawning areas was observed in spatial survey data, indicating strong interactions between the species. A negative temporal relationship was observed also between adult perch and stickleback in coastal fish monitoring programmes supporting the hypothesis that stickleback may have negative population level effects on coastal fish predators. The recent increase in stickleback populations in different basins of the Baltic Sea in combination with

    The 11-million gallon Exxon Valdez oil spill highlighted deficiencies in the nation's ability to contain and recover spilled oil. The Oil Pollution Act of 1990 represents a major effort by Congress to address these deficiencies and to clarify the roles and responsibilities of the private sector and the federal government in preventing, preparing for, and responding to oil spills. This report examines the Coast Guard's efforts to avoid unnecessary and wasteful duplication by coordinating with the private sector and others, including federal and state agencies, its plans to buy oil spill response equipment and the new responsibilities the act places on the private sector and the Coast Guard and if these responsibilities call for a shift in emphasis in Coast Guard oil spill response activities

  16. On the importance of Major Baltic Inflows for oxygenation of the central Baltic Sea

    In December 2014, the third strongest salt water inflow into the Baltic Sea occurred since 1880. It was assumed that the inflow would turn the entire bottom water of the Baltic Sea from anoxic into oxic conditions for an extended period. However, already in late 2015, the central Eastern Baltic Sea had turned back into anoxic conditions. This rapid oxygen decline was in fact surprising since a weaker inflow in 2003 ventilated the Baltic Sea for a longer period of time. With the aid of an ecosystem model of the Baltic Sea, the two inflows in 2003 and 2014 were analyzed in detail. Although the 2014 inflow event was twice as strong as the 2003 inflow event, oxygen transport continued after the latter one, supplying about the same amount of oxygen again. In addition to the major inflow event, a series of smaller inflows in 2003 supplied the extra oxygen transport. Therefore, the strength of a major inflow event alone cannot be used to predict the oxygenation impact. Instead, it is necessary to consider smaller events, in particular those occurring just before and after a major inflow event, as well. An element tagging method showed that the share of oxygen imported across the Danish Straits on the total oxygen arriving at the central Eastern Baltic Sea is between 10% and 20%. Therefore, the oxygen concentration of the inflowing water seems to be of less importance for the oxygenation effect on the central Baltic Sea due to the strong dilution effect.

    Organohalogen contaminants were investigated in Baltic herring caught from three catchment areas in the Baltic Sea, off the coasts of Finland. Pools of both small and large herring were analysed for polychlorinated biphenyls (PCB), dibenzo-p-dioxins, dibenzofurans, naphthalenes, camphenes (toxaphene), polybrominated diphenyl ethers and the pesticide DDT and its metabolites. PCB concentrations per fresh weight in small herring were at the same level in all catchment areas, i.e. the Bothnian Bay, the Bothnian Sea and the Gulf of Finland, revealing no hot spots and reflecting most likely long term emissions and atmospheric deposition. Differences in the levels and/or congener profiles of other contaminants between catchment areas may be explained by point sources. Similar concentrations in small and large herring in the Gulf of Finland were possibly due to their common nutrition. In the other areas, differences between small and large herring most likely reflected their different food sources. - Sources of pollutants are reflected in levels and congener profiles of pollutants in Baltic herring

    According to the tasks of the Russian Science Foundation project "Physical and dynamical properties of marine microplastics particles and their transport in a basin with vertical and horizontal salinity gradient on the example of the Baltic Sea" number 15-17-10020, a comprehensive expeditionary program of measurements in the South-Eastern Baltic started. The project is aimed at finding solutions for a number of problems caused by superfluous plastic pollution in the World Ocean and, in particular, in the Baltic Sea. This pollution has been accumulating for years and just recently it has become obvious that only multidisciplinary approach (geographical, biological, chemical, etc.) to the issues related to the processes of transformation of properties and propagation of plastic particles will allow the study of physical aspects of the problem. During the first stage of the study samples should be selected from the water surface, water column at various horizons, bottom sediments in the Baltic Sea, from different areas at the beaches - in order to further examine the qualitative and quantitative composition of microplastic particles in different seasons for different hydrophysical situations. Reconnaissance survey was begun to choose the fields for research close to point and distributed sources of microplastics. Preference is given to those beaches that are exposed to maximum anthropogenic pollution: areas around the town of Baltiysk, the northern part of the Vistula Spit (near the settlement of Kosa), and the Sambia peninsula coast (settlements of Yantarny, Donskoye, Primorye, Kulikovo, towns of Svetlogorsk, Pionersky, Zelenogradsk). Locations for experimental sites were found in order to assess time for formation of microplastics (Vistula Spit, Kosa settlement). In June-November, 2015 there were 5 expeditions in the waters of the South-Eastern Baltic, 7 expeditions along the coast line of the Baltic Sea (in Kaliningrad Oblast), and 5 expeditions to the Vistula

    A study of the water-mass circulation of the Baltic has been undertaken by making use of a three dimensional Baltic Sea model simulation. The saline water from the North Atlantic is traced through the Danish Sounds into the Baltic where it upwells and mixes with the fresh water inflow from the rivers forming a Baltic haline conveyor belt. The mixing of the saline water from the Great Belt and Oresund with the fresh water is investigated making use of overturning stream functions and Lagrangian trajectories. The overturning stream function was calculated as a function of four different vertical coordinates (depth, salinity, temperature and density) in order to understand the path of the water and where it upwells and mixes. Evidence of a fictive depth overturning cell similar to the Deacon Cell in the Southern Ocean was found in the Baltic proper corresponding to the gyre circulation around Gotland, which vanishes when the overturning stream function is projected on density layers. A Lagrangian trajectory study was performed to obtain a better view of the circulation and mixing of the saline and fresh waters. The residence time of the water masses in the Baltic is calculated to be 26-29 years and the Lagrangian dispersion reaches basin saturation after 5 years.

    2010-01-01

    This paper reviews 17 measures to reduce phosphorus leakage from Swedish agriculture to surface waters. Our aim is to evaluate the possible contribution from agriculture to achieve environmental goals including the Baltic Sea Action Plan. Using a regional approach integrating the variability in field specific characteristics, typical costs and national potential for the included measures may be estimated without identifying, e.g., suitable individual fields for implementation. The result may be helpful to select suitable measures but may also influence the design of environmental targets before they are determined. We find that the cheapest measures are reduced phosphorus content in animal food and fertilizer application supervision in pig farms, both measures with annual potentials of around 50t each, and costs of euro7 to euro11 kg(-1)yr(-1). The total potential of the listed measures is an annual phosphorus reduction to surface waters of 242t. If the most expensive measures are excluded (>euro1000 kg(-1)yr(-1)) and including retention in lakes the phosphorus transport to the sea could be reduced by 165 t yr(-1). This amount can be compared with the Swedish commitment in the Baltic Sea Action Plan (BSAP) to reduce input to the Baltic Proper by 290 t yr(-1).

    This volume originates from a workshop on Economics of the Environment held at the Institute of Economics, Copenhagen University, November 14-15, 1990 with participants from Lithuania, Estonia, Poland, Finland, Sweden and Denmark. The volume contains the papers presented at the workshop. In all the countries around the Baltic Sea there has been an increasing understainding of the importance of using the economic incentive approach to reach environmental goals. By changing the incentives an individual producer or consumer faces, the best private choice can be made to coincide with the best social choice. All the countries around the Baltic Sea have used direct regulation or command and control in environment regulation. Growing concern about environmental degradation, dissatisfaction with the command and control approach and the need to extend environmental regulation to sectors with a large number of small producers or consumers have increased attention to economic instruments in environmental policy. The Baltic sea is an almost coherent ecological system and there is a growing interest in addressing common environmental problems among the countries around the Baltic Sea. The recent political development offer new possibilites for cooperation in environmental policy. This is important because many environmental problems in the region require solutions involving several countries. (EG)

  10. Land surface modelling in hydrology and meteorology – lessons learned from the Baltic Basin

    Directory of Open Access Journals (Sweden)

    L. P. Graham

    2000-01-01

    Full Text Available By both tradition and purpose, the land parameterization schemes of hydrological and meteorological models differ greatly. Meteorologists are concerned primarily with solving the energy balance, whereas hydrologists are most interested in the water balance. Meteorological climate models typically have multi-layered soil parameterisation that solves temperature fluxes numerically with diffusive equations. The same approach is carried over to a similar treatment of water transport. Hydrological models are not usually so interested in soil temperatures, but must provide a reasonable representation of soil moisture to get runoff right. To treat the heterogeneity of the soil, many hydrological models use only one layer with a statistical representation of soil variability. Such a hydrological model can be used on large scales while taking subgrid variability into account. Hydrological models also include lateral transport of water – an imperative if' river discharge is to be estimated. The concept of a complexity chain for coupled modelling systems is introduced, together with considerations for mixing model components. Under BALTEX (Baltic Sea Experiment and SWECLIM (Swedish Regional Climate Modelling Programme, a large-scale hydrological model of runoff in the Baltic Basin is used to review atmospheric climate model simulations. This incorporates both the runoff record and hydrological modelling experience into atmospheric model development. Results from two models are shown. A conclusion is that the key to improved models may be less complexity. Perhaps the meteorological models should keep their multi-layered approach for modelling soil temperature, but add a simpler, yet physically consistent, hydrological approach for modelling snow processes and water transport in the soil.

The modelling results are validated with station (water temperature and satellite data (ice concentration as well as by qualitative comparisons with the Swedish Meteorological and Hydrological Institute ice charts. Analysis of the results addresses two major questions. One concerns effects of meteorological forcing on the spatio-temporal distribution of ice concentration in the Baltic. Patterns of correlations between air temperature, wind speed, and ice-covered area are demonstrated to be different in larger, more open sub-basins (e.g., the Bothnian Sea than in the smaller ones (e.g., the Bothnian Bay. Whereas the correlations with the air temperature are positive in both cases, the influence of wind is pronounced only in large basins, leading to increase/decrease of areas with small/large ice concentrations, respectively. The other question concerns the role of ice dynamics in the evolution of the ice cover. By means of simulations with the dynamic model turned on and off, the ice dynamics is shown to play a crucial role in interactions between the ice and the upper layers of the water column, especially during periods with highly varying wind speeds and directions. In particular, due to the fragmentation of the ice cover and the modified surface fluxes, the ice dynamics influences the rate of change of the total ice volume, in some cases by as much as 1 km3 per day. As opposed to most other numerical studies on the sea-ice in the Baltic Sea, this work concentrates on the short-term variability of the ice cover and its response to the synoptic-scale forcing.

  12. Security Policy at Road’s End? The Roles of Sweden and Finland in the Nordic-Baltic Defence Cooperation Process

    Directory of Open Access Journals (Sweden)

    Winnerstig Mike

    2014-12-01

    Full Text Available The article addresses a number of questions related to Nordic and to an extent also Nordic-Baltic defence cooperation. First of all, how far has Nordic and Nordic-Baltic defence cooperation come today? Secondly, what are the differences in the approaches of Sweden and Finland when it comes to defence cooperation, especially regarding NATO, in the Nordic-Baltic area? As a first analytical result, it is apparent that the rhetorical standing of the Nordic and Nordic-Baltic defence cooperation process is greater than its real achievements, especially in terms of defence integration. Secondly, it seems also to be clear that the defence and security policy debates of Sweden and Finland are quite different. Some problems identified in the debates within the two countries, respectively, are very similar although the suggested solutions vary very remarkably. Regarding the key issue of NATO membership, the developments of the last few years suggest that the Swedish political establishment, as well as the general public, might be closer to a substantial discussion of NATO membership than their Finnish equivalents.

  13. Nord stream: not just a pipeline. An analysis of the political debates in the Baltic Sea region regarding the planned gas pipeline from Russia to Germany

    This report is an analysis of the planned gas pipeline from Russia to Germany through the Baltic Sea known as Nord Stream. Although not yet realised, the project has, since its birth, been the subject of harsh criticism and opposition by a significant number of states that consider themselves affected by the pipeline. Whereas the Baltic States and Poland have interpreted the pipeline as a politically motivated strategy that will increase Russia's leverage on them and threaten their energy security, the debate in Sweden was at first mostly concerned with the prospect of increased Russian military presence in the Swedish Exclusive Economic Zone. The potential environmental impact of the pipeline has been, and continues to be, an overarching concern shared by all the littoral states of the Baltic Sea. Proponents of Nord Stream, most notably Germany, Russia and the Nord Stream consortium, have largely dismissed the concerns as unwarranted and argue that the pipeline is a common European project that all EU-members should embrace, as it will provide much-needed gas to an increasingly energy-thirsty union. This report is an extensive study of the divergent attitudes and debates that have surged in the region regarding Nord Stream, and the aim is to provide plausible explanations as to why the interpretations of the project have been so different in the various states. The report is based on a variety of sources, including several first-hand interviews with researchers and government officials in the Baltic Sea region. (author). refs.,fig.,tabs

    Brucella infection in seals was reported for the first time in 1994 around the coast of Scotland. Since then, marine mammal Brucella infections were found to be widely distributed in the northern hemisphere. Two Brucella species affect marine mammals: Brucella pinnipedialis in pinnipeds and Brucella ceti in cetaceans. We examined the livers of Baltic grey seals (Halichoerus grypus) from the Finnish coast (n=122) hunted, found dead, or killed as by-catch in fishing gear in 2013-15 as part of population health monitoring. We detected B. pinnipedialis in the livers of three grey seals. The bacterium was isolated from livers displaying parasitic cholangitis. We also detected Brucella DNA in liver flukes (Pseudamphistomum truncatum) obtained from a Brucella-infected grey seal, suggesting that flukes might be possible vectors of this pathogen in the marine environment.

    The climate changes in recent years in the southern Baltic have been resulting in an increased frequency of natural extreme phenomena (i.e. storms, floods) and intensification of abrasion processes, which leads to introduction of large amounts of sedimentary deposits into the marine environment. The aim of this study was to determine the mercury load introduced to the Baltic Sea with deposits crumbling off the cliffs-parts of the coast that are the most exposed to abrasion. The studies were carried out close to five cliffs located on the Polish coast in the years 2011-2014. The results show that coastal erosion could be an important Hg source into the marine environment. This process is the third most important route, after riverine and precipitation input, by which Hg may enter the Gulf of Gdańsk. In the Hg budget in the gulf, the load caused by erosion (14.3 kg a(-1)) accounted for 80 % of the wet deposition and was 50 % higher than the amount of mercury introduced with dry deposition. Although the Hg concentration in the cliff deposits was similar to the natural background, due to their large mass, this problem could be significant. In addition, the preliminary studies on the impact of coastal erosion on the Hg level in the marine ecosystem have shown that this process may be one of the Hg sources into the trophic chain.

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990). The R and D activities are updated to September 1981

  4. The Öland limestone - A Swedish stone used for more than one thousand years

    Science.gov (United States)

    Schouenborg, Björn; Wickström, Linda; Mikaelsson, Jan

    2016-04-01

    The second largest island in Sweden is the home of the "Öland limestone", a condensed and bedded limestone whose origin dates back to Lower Ordovician, i.e. about 480 M years ago. Öland is a part of the palaeocontinent Baltica that, at the time, was situated at low latitudes with deposition of the calcareous sediments in a cool water environment. The limestone on Öland represents a proximal ramp tectonic setting, with the oldest sediments deposited in the west and younger sediments deposited towards east and southeast. Fluctuating sea-levels have created erosional hard grounds such as the Flowery sheet. These hardgrounds are recognised by their vivid colours and trace fossils, and can be traced all over Baltica, but is maybe best represented on Öland. Ordovician limestones are present in many places in Sweden, but it is the occurrence on Öland that is the most renowned in a building stone perspective. One reason for this is the favourable trading location, an island off the Swedish East coast in middle of the trading routes between the Baltic countries and the continent. Other reasons are the pleasant aesthetical values with numerous orthoceratites and other fossils. The limestones on Öland differ in colour. From the red varieties (with oxidized iron) to brownish and grey. The bedding is mostly in the cm-scale which easily enables very exploitable thickness of slabs. Every mm limestone represents about 1000 years of deposition. The limestone has most likely been used in a very crude way for many thousand years, but archaeological evidence of a more industrialized usage is just a little more than 1000 years. It is known from the literature that the first official Swedish king, Gustav Vasa (16th century), desired this stone. At the time it was called "Öland marble", and the king "imported" specialists to process it further at the Royal Stone workshop on northern Öland. Remnants of tools and working sites still remain in an outdoor museum. Export of the

    Highlights: • A dynamic model was developed to evaluate changes in the energy system till 2050. • Wind energy has the potential to become dominant in the Baltic region. • Solar energy has the potential to become popular from 2025 till 2050. - Abstract: The European Union has given a long-term commitment towards a low-carbon society. Power sector is to play an important role in achieving ambitious emission reduction goals. This article presents results of a research aimed at evaluating development of the Baltic power system under current framework conditions. Special focus is put on renewable energy analysis to estimate the potential of power sector decarbonization. A dynamic energy-economy model was developed by applying system dynamics modelling approach in order to evaluate changes in the energy system till 2050. Underlying structure of the model is based on energy resource flows according to the national electricity mix of each Baltic State. The model calculates energy generation costs of each technology taking into account national support schemes. Based on cost estimation, the installed capacity of each energy resource is determined. Modelling results suggest that wind energy has the potential to become dominant in the Baltic region. This is explained by increasing competitiveness of wind-generated power price compared to fossil-fuel-based generation. Solar energy has the potential to become popular from 2025 onwards due to decreasing investment costs. The market share of other renewable electricity technologies, such as hydro and biomass, will continue to increase reaching maximum between 2020 and 2030. Biogas plants are still not expected to play considerable role in electricity generation.

    The GLOBEC Germany program (2002-2007) had the ambitious goal to resolve the processes impacting the recruitment dynamics of Baltic sprat (Sprattus sprattus L.) by examining various factors affecting early life history stages. At the start of the research program, a number of general recruitment hypotheses were formulated, i.e. focusing on (1) predation, (2) food availability, (3) physical parameters, (4) the impact of current systems, and finally (5) the importance of top-down vs bottom-up effects. The present study synthesizes the results of field sampling (2002 and 2003), laboratory experiments, and modeling studies to re-evaluate these hypotheses for the Baltic sprat stock. Recruitment success was quite different in the 2 years investigated. Despite a lower spawning stock biomass in 2003, the total number of recruits was almost 2-fold higher that year compared to 2002. The higher recruitment success in 2003 could be attributed to enhanced survival success during the post-larval/juvenile stage, a life phase that appears to be critical for recruitment dynamics. In the state of the Baltic ecosystem during the period of investigation, we consider bottom-up control (e.g. temperature, prey abundance) to be more important than top-down control (predation mortality). This ranking in importance does not vary seasonally. Prevailing water circulation patterns and the transport dynamics of larval cohorts have a strong influence on sprat recruitment success. Pronounced transport to coastal areas is detrimental for year-class strength particularly at high sprat stock sizes. A suggested mechanism is density-dependant regulation of survival via intra- and inter-specific competition for prey in coastal areas. A documented change in larval vertical migration behavior between the early 1990s and early 2000s increased the transport potential to the coast, strengthening the coupling between inter-annual differences in the magnitude and direction of wind-driven surface currents and

  9. Status of grey seals along mainland Europe from the Southwestern Baltic to France

    Full Text Available The grey seal was a common species along mainland Europe during the Stone Age (8,000-5,500 BC. Along the North Sea coast populations started to decline substantially during the 11th century as a result of excessive hunting. The last breeding populations disappeared in the 16th century in the Wadden Sea, and before 1900 in the Kattegat-Skagerrak and the Southwestern Baltic as a result of an extermination campaign. No regular pupping occurred along mainland Europe until the end of the 1970s, when a breeding colony was established near Amrum in the German Wadden Sea. Somewhat later, additional breeding sites were discovered near Terschelling in the Dutch Wadden Sea (1980, at Helgoland, and off Brittany in France. Tracking of movements indicate these seal groups to be linked to the larger populations in the UK. Numbers of grey seals in the recolonised areas have increased over the years, but in the Kattegat-Skagerrak stable numbersof about 25 individuals have been observed since the 1970s, whereas more than 100 grey seals are found in the Southwestern Baltic. In the southeastern North Sea, 120 grey seals occur during moult at Helgoland, 120 in the German and over 1,130 in the Dutch parts of the Wadden Sea in 2004. Along the southern Dutch and Belgian coasts small groups are regularly observed, but no colonies have yet been established. In the colonies off Brittany in France about 105 grey seals have been counted. Successful pupping has only been recorded 3 times in the Kattegat-Skagerrak over the past 30 years, and 2-4 pups are born annually in France and the Southwestern Baltic. The relative strongholds for breeding along the European continent are the Dutch Wadden Sea, where in 2003/2004 at least 150 pups were recorded, Amrum in the German Wadden Sea (23 pups and Helgoland (8 pups. Consequently, total numbers of counted grey seals from the Southwestern Baltic to France amounted to at least 1,600 in 2004, while about 190 pups were born in the area.

    Full Text Available Obstetric thromboprophylaxis is difficult. Since 10 years Swedish obstetricians have used a combined risk estimation model and recommendations concerning to whom, at what dose, when, and for how long thromboprophylaxis is to be administrated based on a weighted risk score. In this paper we describe the background and validation of the Swedish guidelines for obstetric thromboprophylaxis in women with moderate-high risk of VTE, that is, at similar or higher risk as the antepartum risk among women with history of thrombosis. The risk score is based on major risk factors (i.e., 5-fold increased risk of thromboembolism. We present data on the efficacy of the model, the cost-effectiveness, and the lifestyle advice that is given. We believe that the Swedish guidelines for obstetric thromboprophylaxis aid clinicians in providing women at increased risk of VTE with effective and appropriate thromboprophylaxis, thus avoiding both over- and under-treatment.

    Full Text Available The Baltic region consists of coastal areas of nine countries — Russia, Estonia, Latvia, Lithuania, Poland, Germany, Denmark, Sweden, and Finland. The region’s hubs are the port cities located along the Baltic Sea coast. However, Peter Taylor and Saskia Sassen’s classification identifies higher status cities and ‘global cities’, which are to be considered in the global context. Seven coastal regions are distinguished within this region, whose organising centers are the global coastal cities of Stockholm, Copenhagen, Helsinki, Riga, Tallinn, St. Petersburg, and Malmö. The concept of a “global city-region” (Sassen can be used as a methodological framework for analyzing this connection. Within this hierarchy, the dominant alpha group global city is Stockholm. The authors argue that, as a global coastal city, St. Petersburg forms the St. Petersburg coastal region, which can be defined as a typical "global city region". The index method shows that the position of St. Petersburg in the system of global coastal cities of the Baltic region is relatively favorable in view of its transport, logistics, and demographic potential and the advantageous geo-economic situation. St. Petersburg has certain competitive advantages in the region brought about by its demographic potential, port freight capacity, and the favorable geo-economic position of the "sea gate" of Russia. However, the level of high-tech services and ‘new economy’ development is not sufficient for the port to become a match for the top three cities (Stockholm, Helsinki, and Copenhagen. This is increasingly important because transboundary global city networks demonstrate that global cities are functions of global networks. Saint Petersburg is just starting to integrate into these networks through the Pulkovo airline hub and seaports of Ust-Luga, Primorsk, and Saint Petersburg.

  4. Saints and Sainthood around the Baltic Sea

    DEFF Research Database (Denmark)

    This collection of articles covers most of the Baltic Region with a special focus on the cult of saints in Russia, Prussia, Finland, Sweden, Denmark, Estonia and Latvia (more commonly referred to in the Middle Ages as Livonia). The articles cover a wide range of topics, for example the introduction...... of foreign (and ‘old’) saints into new regions, the creation of new local cults of saints in newly Christianized regions, the role of the cult of saints in the creation of political and lay identities, the adaption of the cult of saints in folk poetry and the potential role of saints in times of war...

    This paper presents the results of an investigation of the 210 Po contents of Baltic marine invertebrates. The 210 Po concentrations fall within the range 11.3-78.9 Bq kg -1 (dry wt), the higher values relating to polychaeta, priapulida and malacostraca and the lower levels to bivalvia. It is demonstrated that 210 Po is non-uniformly distributed within the isopod Mesidotea entomon and the bivalve Mya arenaria. The 210 Po contents of the internal organs decreasing in the order-hepatopancreas > alimentary tract > gill > muscle. Moreover, the results indicate the dominant role of the digestive organs of these invertebrates in controlling absorption and elimination of 210 Po. (author)

  6. Problem zone and pioneer region. The Baltic region between controversies of energy policy and cooperative projects; Problemzone und Vorreiterregion. Der Ostseeraum im Spannungsfeld energiepolitischer Kontroversen und Kooperationsvorhaben

    Lang, Kai-Olaf

    2010-10-15

    This publication describes how for the EU states bordering on the Baltic coast energy policy and energy economy have become crucial fields of bilateral and regional cooperation. On the one side this is attributable to the controversial Nord Stream Pipeline, growing concerns over the security of supply, vulnerabilities in energy policy - be they real or imagined - and to competing energy economic interests. On the other side, what has drawn numerous players' attention to the greater Baltic region as an attractive area in terms of energy policy are the prospects for multilateral cooperation projects and associated hopes for greater regional solidarity in issues of energy policy. In this sense the Baltic region is not only an energy political problem zone but also a potential pioneer region, namely when it comes to energy economic and energy political integration within the EU. This ambivalence should continue to characterise the region for the foreseeable future. The extent to which energy economic integration will in future prevail over particular national interests of energy and security policy will greatly depend on the initiatives which the EU Baltic states succeed in launching cooperatively at EU level.

    The shipworm, Teredo navalis, is absent from most of the Baltic Sea. In the last 20 years, increased frequency of T. navalis has been reported along the southern Baltic Sea coasts of Denmark, Germany, and Sweden, indicating possible range-extensions into previously unoccupied areas. We evaluated the effects of historical and projected near-future changes in salinity, temperature, and oxygen on the risk of spread of T. navalis in the Baltic. Specifically, we developed a simple, GIS-based, mechanistic climate envelope model to predict the spatial distribution of favourable conditions for adult reproduction and larval metamorphosis of T. navalis, based on published environmental tolerances to these factors. In addition, we used a high-resolution three-dimensional hydrographic model to simulate the probability of spread of T. navalis larvae within the study area. Climate envelope modeling showed that projected near-future climate change is not likely to change the overall distribution of T. navalis in the region, but will prolong the breeding season and increase the risk of shipworm establishment at the margins of the current range. Dispersal simulations indicated that the majority of larvae were philopatric, but those that spread over a wider area typically spread to areas unfavourable for their survival. Overall, therefore, we found no substantive evidence for climate-change related shifts in the distribution of T. navalis in the Baltic Sea, and no evidence for increased risk of spread in the near-future.

  9. Environmental assessment of Swedish agriculture

    2007-01-01

    This article describes an environmental assessment of Swedish agriculture, including upstream and downstream effects. The analysis is based on environmentally extended input-output analysis, but it is also supplemented with data from other sources. The analysis shows that direct effects by the Swedish agriculture are the most important, while indirect effects from other sources including mobile and impacts abroad are also considerable. The most important impacts from Swedish agriculture according to the analysis are eutrophication, global warming and resource use. The agricultural sector produces a large share of the Swedish emissions causing both global warming and eutrophication. In addition, current agricultural practice causes problems with loss of biodiversity. The most important actors in the sector are agriculture itself, but also all actors using fossil fuels: primarily the transport sector and the energy sector. In addition, consumers are important since they can influence the composition of agricultural production. The analysis shows the importance of including upstream and downstream effects when analysing the environmental impacts from a sector. (author)

  10. Egg production of turbot, Scophthalmus maximus, in the Baltic Sea

    2013-11-01

    In the brackish water Baltic Sea turbot spawn at ~ 6-9 psu along the coast and on offshore banks in ICES SD 24-29, with salinity influencing the reproductive success. The potential fecundity (the stock of vitellogenic oocytes in the pre-spawning ovary), egg size (diameter and dry weight of artificially fertilized 1-day-old eggs) and gonad dry weight were assessed for fish sampled in SD 25 and SD 28. Multiple regression analysis identified somatic weight, or total length in combination with Fulton's condition factor, as main predictors of fecundity and gonad dry weight with stage of maturity (oocyte packing density or leading cohort) as an additional predictor. For egg size, somatic weight was identified as main predictor while otolith weight (proxy for age) was an additional predictor. Univariate analysis using GLM revealed significantly higher fecundity and gonad dry weight for turbot from SD 28 (3378-3474 oocytes/g somatic weight) compared to those from SD 25 (2343 oocytes/g somatic weight), with no difference in egg size (1.05 ± 0.03 mm diameter and 46.8 ± 6.5 μg dry weight; mean ± sd). The difference in egg production matched egg survival probabilities in relation to salinity conditions suggesting selection for higher fecundity as a consequence of poorer reproductive success at lower salinities. This supports the hypothesis of higher size-specific fecundity towards the limit of the distribution of a species as an adaptation to harsher environmental conditions and lower offspring survival probabilities. Within SD 28 comparisons were made between two major fishing areas targeting spawning aggregations and a marine protected area without fishing. The outcome was inconclusive and is discussed with respect to potential fishery induced effects, effects of the salinity gradient, effects of specific year-classes, and effects of maturation status of sampled fish.

  11. Tectonic framework of the Hanoe Bay area, southern Baltic Sea

    The tectonic framework and the general geologic development of the Hanoe Bay, from the Scanian coast in the west to south of Oeland in the east, has been investigated by means of reflection seismic methods. The Hanoe Bay is in this paper subdivided into four areas of different geologic settings. These are: 1) The Hanoe Bay slope, which forms a southward dipping continuation of the rigid Blekinge coastal plain. 2) The eastward dipping Kalmarsund Slope, which southwards from Oeland forms the western part of the Paleozoic Baltic Syneclise. 3) The Mesozoic Hanoe Bay Halfgraben, which forms the central and southern parts of the Hanoe Bay. The ongoing subsidence of the Halfgraben is estimated to be in the order of 20-60 m during the Quaternary. 4) The Yoldia Structural Element, which forms a deformed, tilted and possibly rotated block of Paleozoic bedrock located east of the Hanoe Bay Halfgraben. Two tectonic phases dominate the post-Paleozoic development of the Hanoe Bay, these are: 1) The Early Kimmerian phase, which initiated subsidence and reactivated older faults. 2) The Late Cretaceous phase, which is the main subsidence phase of the Hanoe Bay Halfgraben. The tectonic fault pattern of the Hanoe Bay is dominated by three directions, i.e. NW-SE, NE-SW and WNW-ESE. The two main tectonic elements of the area are the Kullen-Christiansoe Ridge System (NW-SE) and the Bornholm Gat Tectonic Zone (NE-SW). Sinistral strike-slip movements in order of 2-3 km are interpreted to have occurred along the Bornholm Gat Tectonic Zone during the late Cretaceous. 20 refs, 19 figs

  12. The geology of the southeastern Baltic Sea: a review

    The Baltic Sea, particularly its southeastern part, is discussed in the paper. Investigations of regional character as well as specialized studies in the area are reviewed. General historical works are mentioned briefly. Previous surveys since the 1950s are presented by the subject studied. The compilation of geological structure of the SE Baltic Sea bottom and adjacent land of Balticum (Baltic States: Estonia, Latvia, Lithuania) is based on considerable amounts of summarized materials. The crystalline basement, sedimentary cover and Quaternary deposits are characterized in the comprehensive survey of geological structure. From a stratigraphical point of view, geological sequence of the platformal cover is comparatively complete: deposits of all geological systems (from the Archean to Cenozoic) are present in the Baltic Syneclise. Considering geotectonical cycles, the sedimentary cover of the syneclise is subdivided into four structural complexes. The thickness and distribution of Quaternary deposits are closely related to the recent bottom relief of the Baltic Sea that in turn is inherited from the Pre-Quaternary surface. Buried palaeo-valleys are characteristic of the Pre-Quaternary surface in the Baltic region and the Baltic Sea bottom. The Quaternary is characterized by layers of various geneses and by sharp changes of their thicknesses.

  13. The Baltic policy of Germany and current international relations

    Full Text Available This article analyses the Baltic policy of united Germany from the 1990s until today. The authors set out to identify the significance of German-Baltic relations and the role of the Eastern policy in Russian-German relations. The method of dynamic comparison between the political and economic narrative in intergovernmental relations makes it possible to identify distinctive features of Germany’s Baltic policy in the context of current international relations. In particular, it is noted that Germany was most active in the Baltic region in the 1990s, when the country was establishing political, economic, and cultural ties with the new independent states. In the second half of the 1990s, Germany’s foreign policy became less intense. After the accession of Lithuania, Latvia, and Estonia to the EU and NATO in 2004, certain disagreements started to arise between Germany and the Baltics. It explains the lukewarm relations between them. The Ukraine events brought about a change in Germany’s regional policy. Despite Russia remaining one of the key economic and political counteractors, Germany, being a partner of the Baltics in the EU and NATO, cannot adopt a neutral position in the conflict of interests between the Baltics and Russia.

    2013 is a significant year for the Baltic states in their relations with European integration. On 1 July 2013, Lithuania became the first of the Baltic states to hold the rotating presidency of the EU Council of ministers. Its performance is closely watched by Latvia and Estonia, whose turns to hold the presidency come in 2015 and 2018, respectively. In addition, this year Latvia has been invited to join the Euro Area thus becoming the second Baltic state after Estonia to share the common currency. This Study aims to show that these developments are extremely important for the young and small Baltic states, which continue to aspire to secure their place in the European 'core'. Having emerged from the crisis as good students of internal devaluation, the Baltic states have a window of opportunity to voice their main concerns and priorities regarding the future of European integration. Lithuanian presidency puts an emphasis on more economic growth and credibility within the E(M)U as well as increased energy security, the challenges that have been daunting the Baltic states in the past years and decades. In order to better understand the origins and the significance of these priorities, this Study is divided into three distinct parts dealing with historical and political context of the three Baltic states (Part 1), the causes and consequences of the recent economic crisis (Part 2) and specific issues related to the energy policy in the region (Part 3)

    Full Text Available In this paper, we discuss variations seen in the ornamentation and modes of manufacturing pottery from the end of the mid-Neolithic 4600–4300 BP on the Island of Gotland in the Baltic Sea. The Pitted Ware cultural groups have been discussed as a western influence from the Swedish mainland, but the aDNA on skeletal remains point to eastern influences. We analyse and discuss pottery from the well-investigated Ajvide Pitted Ware site and what these variations mean in term of intra- and inter-island relationships, ethnicity and change, and we suggest the development of what could be described as a hybrid culture.

  16. Sulfur problems in Swedish agriculture

    Johansson, O

    1959-01-01

    The present paper deals with some aspects of the sulfur situation in Swedish agriculture with special emphasis on the importance of and relationships among various sources of sulfur supply. An inventory of the sulfur content of Swedish soils and hay crops includes 649 soil samples and a corresponding number of hay samples from 59 locations. In a special investigation the samples were found to be representative of normal Swedish farm land. It is concluded that the amount of sulfur compounds in the air is the primary factor which determines the amount of sulfur added to the soil from the atmosphere. Compared with values obtained in other countries, the amount of sulfur added by the precipitation in Sweden is very low. The distribution in air and precipitation of sulfur from an industrial source was studied in a special investigation. An initial reason for the present study was the damage to vegetation caused by smoke from an industrial source. It was concluded that the average conditions in the vicinity of the industrial source with respect to smoke constituents in the air and precipitation were unfavorable only to the plants directly within a very narrow region. Relationships among the sulfur contents of air, of precipitation, of soils and of plants have been subject to special investigations. In the final general discussion and conclusions it is pointed out that the results from these investigations indicate evident differences in the sulfur status of Swedish soils. The present trend toward the use of more highly concentrated fertilizers poor in sulfur may be expected to cause a considerable change in the sulfur situation in Swedish agriculture. 167 references, 40 figures, 44 tables.

    In this study, the population history of the Baltic Sea region, known to be affected by a variety of migrations and genetic barriers, was analyzed using both mitochondrial DNA and Y-chromosomal data. Over 1200 samples from Finland, Sweden, Karelia, Estonia, Setoland, Latvia and Lithuania were genotyped for 18 Y-chromosomal biallelic polymorphisms and 9 STRs, in addition to analyzing 17 coding region polymorphisms and the HVS1 region from the mtDNA. It was shown that the populations surrounding the Baltic Sea are genetically similar, which suggests that it has been an important route not only for cultural transmission but also for population migration. However, many of the migrations affecting the area from Central Europe, the Volga-Ural region and from Slavic populations have had a quantitatively different impact on the populations, and, furthermore, the effects of genetic drift have increased the differences between populations especially in the north. The possible explanations for the high frequencies of several haplogroups with an origin in the Iberian refugia (H1, U5b, I1a) are also discussed.

    This thorough review is based on observational satellite, airborne and in-situ data, scientific literature and technical reports, as well as the substantial experience of the authors, who hail from several Baltic Sea countries. They pay special attention to national practices, HELCOM and EMSA CleanSeaNet activities in oil pollution monitoring, and show different applications of the Seatrack Web model for oil spill drift prediction and the identification of illegal polluters, as well as for environmental risk assessment. Furthermore, some of the results on satellite monitoring of the Nord Stream gas pipeline construction in the Gulf of Finland are presented. This volume addresses the needs of specialists working in different fields of marine, environmental, and remote sensing sciences. It is a useful handbook on oil pollution for international and governmental agencies, as well as for policy makers who plan and manage oil and gas projects, the construction of ports and terminals, shipping, fishery, recreation, and tourist activities in the Baltic Sea.

    Full Text Available The relevance of the study lies in the acute need to modernise the tools for a more accurate and comparable reflection of the demographic reality of spatial objects of different scales. This article aims to test the methods of “demographic rankings” developed by Yermakov and Shmakov. The method is based on the principles of indirect standardisation of the major demographic coefficients relative to the age structure.The article describes the first attempt to apply the method to the analysis of birth and mortality rates in 1995 and 2010 for 140 countries against the global average, and for the Baltic Sea states against the European average. The grouping of countries and the analysis of changes over the given period confirmed a number of demographic development trends and the persistence of wide territorial disparities in major indicators. The authors identify opposite trends in ranking based on the standardised birth (country consolidation at the level of averaged values and mortality (polarisation rates. The features of demographic process development in the Baltic regions states are described against the global and European background. The study confirmed the validity of the demographic ranking method, which can be instrumental in solving not only scientific but also practical tasks, including those in the field of demographic and social policy.

    In June 2006, FOI published the report: Sweden and the NEGP: a Pilot Study of the North European Gas Pipeline and Sweden's Dependence on Russian Energy, a base data report on a topic that FOI considered to be of rising importance. Much has happened since then and the NEGP has changed its name to Nord Stream and submitted an official notification on the intention of realising the project of constructing a gas pipeline from Russia to Germany via the Baltic Sea. The primary aim of this report is to discuss and analyse some of the core aspects of Nord Stream and the pipeline project with regard to the security situation for the Baltic Sea region. The report constitutes an updated version of the previous report. Most of the old report still stands valid, especially concerning the historical survey of Russia's energy policy, but the new report has additional chapters and is broader in scope concerning the consequences of the project

    From Russia in the east to Sweden, Denmark, and Germany in the west, reaching south to the tips of the Czech Republic, Slovakia, and Ukraine, the Baltic Sea watershed drains nearly 20% of Europe (see Figure 1). In the highly populated south, the temperate climate hosts intensive agriculture and industry. In the north, the landscape is boreal and rural. In the Baltic Sea itself, complex bathymetry and stratification patterns as well as extended hypoxic and anoxic deep waters add to the diversity. Yet in recent history, the differences across the Baltic Sea region have been more than physical: In the mid-20th century, the watershed was split in two.

    Full Text Available Temporal variations (1994-98 in nutrient distribution were analysed in the break Polish sector of the Baltic Sea with reference to long-term (1979-98 fluctuations of hydrological and chemical factors. Between 1994 and 1998 the winter accumulation of phosphate declined noticeably in most of the regions with the exception of the Gulf of Gdansk. The winter peaks of silicate were also reduced in the offshore region and in the waters along the central Polish coast, but continued to accumulate in the bays owing to riverine input. In the offshore region a decrease in the winter accumulation of nitrate was noted in the surface water layer whereas in the bays nitrate concentrations continued to increase. Large quantities of nitrate continue to accumulate in the Gulf of Gdansk, although at a slower rate than in 1979-93.

    Over the past 50 years, storminess has increased in northern Europe because of the changes in cyclonic activity. The cyclone season in the Baltic Sea area has shifted from autumn to winter; this has led to intensification of shore processes (erosion, sediment transport and accumulation) and has increased pressure to the economy (land use, coastal protection measures) of the coastal regions in the Baltic states. Therefore, studing the effects of such changes on shore processes in the past is critical for prediction of the future changes along the Baltic coasts. Beach ridge plains are found worldwide, where cyclones and storm surges affect accumulation forms. These sandy shores are highly susceptible to erosion. Due to the isostatic uplift on the NE coast of the Baltic Sea, the signs of major past events are well-preserved in the internal architecture of old coastal formations (dune ridge-swale complexes). Wave-eroded scarps in beach deposits are visible in subsurface ground-penetrating radar (GPR) records, indicating the past high-energy events. Several study areas and transects were selected on the NW coast of Estonia, using high-resolution topographic maps (LiDAR). Shore-normal subsurface surveys have been conducted with a digital GSSI SIR-3000 georadar with a 270 MHz antenna at each transect. Interpretation of GPR facies was based on hand auger and window sampler coring, which provided accurate depths of key stratigraphic boundaries and bounding surfaces. Several samples for luminescence and 14C dating were collected to determine the approximate chronology of the coastal formations along the Estonian coast. We have found that changes in storminess, including the periods of high and low intensity of storms in late Holocene, are clearly reflected in the internal patterns of ancient coastal formations. The sections with small ridges with short seaward-dipped layers (interface between wave-built and aeolian deposits) in deeper horizons are probably formed during

    Short-term increases in soil solution nitrate (NO{sub 3}{sup -}) concentration are often observed after forest harvest, even in N-limited systems. We model NO{sub 3}{sup -} leaching below the rooting zone as a function of site productivity. Using national forest inventories and published estimates of N attenuation in rivers and the riparian zone, we estimate effects of stem-only harvesting on NO{sub 3}{sup -} leaching to groundwater, surface waters and the marine environment. Stem-only harvesting is a minor contributor to NO{sub 3}{sup -} pollution of Swedish waters. Effects in surface waters are rapidly diluted downstream, but can be locally important for shallow well-waters as well as for the total amount of N reaching the sea. Harvesting adds approximately 8 Gg NO{sub 3}-N to soil waters in Sweden, with local concentrations up to 7 mg NO{sub 3}-N l{sup -1}. Of that, {approx}3.3 Gg reaches the marine environment. This is {approx}3% of the overall Swedish N load to the Baltic. - Forest harvesting in Sweden is a minor contributor to N pollution in the Baltic.

  5. Temporal variatiions of Sea ice cover in the Baltic Sea derived from operational sea ice products used in NWP.

    Sea ice cover is a crucial parameter for surface fluxes of heat and moisture over water areas. The isolating effect and the much higher albedo strongly reduces the turbulent exchange of heat and moisture from the surface to the atmosphere and allows for cold and dry air mass flow with strong impact on the stability of the whole boundary layer and consequently cloud formation as well as precipitation in the downstream regions. Numerical weather centers as, ECMWF, MetoFrance or DWD use external products to initialize SST and sea ice cover in their NWP models. To the knowledge of the author there are mainly two global sea ice products well established with operational availability, one from NOAA NCEP that combines measurements with satellite data, and the other from OSI-SAF derived from SSMI/S sensors. The latter one is used in the Ostia product. DWD additionally uses a regional product for the Baltic Sea provided by the national center for shipping and hydrografie which combines observations from ships (and icebreakers) for the German part of the Baltic Sea and model analysis from the hydrodynamic HIROMB model of the Swedish meteorological service for the rest of the domain. The temporal evolution of the three different products are compared for a cold period in Februar 2012. Goods and bads will be presented and suggestions for a harmonization of strong day to day jumps over large areas are suggested.

    Presence of sympatric populations may reflect local diversification or secondary contact of already distinct forms. The Baltic cisco (Coregonus albula) normally spawns in late autumn, but in a few lakes in Northern Europe sympatric autumn and spring- or winter-spawners have been described. So far, the evolutionary relationships and taxonomic status of these main life history forms have remained largely unclear. With microsatellites and mtDNA sequences, we analyzed extant and extinct spring- and autumn-spawners from a total of 23 Swedish localities, including sympatric populations. Published sequences from Baltic ciscoes in Germany and Finland, and Coregonus sardinella from North America were also included together with novel mtDNA sequences from Siberian C. sardinella. A clear genetic structure within Sweden was found that included two population assemblages markedly differentiated at microsatellites and apparently fixed for mtDNA haplotypes from two distinct clades. All sympatric Swedish populations belonged to the same assemblage, suggesting parallel evolution of spring-spawning rather than secondary contact. The pattern observed further suggests that postglacial immigration to Northern Europe occurred from at least two different refugia. Previous results showing that mtDNA in Baltic cisco is paraphyletic with respect to North American C. sardinella were confirmed. However, the inclusion of Siberian C. sardinella revealed a more complicated pattern, as these novel haplotypes were found within one of the two main C. albula clades and were clearly distinct from those in North American C. sardinella. The evolutionary history of Northern Hemisphere ciscoes thus seems to be more complex than previously recognized.

    A first version of a wind atlas for the South Baltic Sea has been developed using the WRF mesoscale model and verified by data from tall Danish and German masts. Six different boundary-layer parametrization schemes were evaluated by comparing the WRF results to the observed wind profiles at the masts. The WRF modeling was done in a nested domain of high spatial resolution for 4 years. In addition the long-term wind statistics using the NCAR-NCEP reanalysis data were performed during 30 years to provide basis for a long-term adjustment of the results and the final WRF results include a weighting for the long-term trends variability in the South Baltic Sea. Observations from Earth observing satellites were used to evaluate the spatial resolution of the WRF model results near the surface. The QuikSCAT and the WRF results compared well whereas the Envisat ASAR mean wind map showed some variation to the others. The long-term analysis revealed that the South Baltic Sea has a spatially highly variable wind climate during the 30-years. (Author)

  8. Nitrogen fixation by cyanobacteria stimulates production in Baltic food webs.

    Filamentous, nitrogen-fixing cyanobacteria form extensive summer blooms in the Baltic Sea. Their ability to fix dissolved N2 allows cyanobacteria to circumvent the general summer nitrogen limitation, while also generating a supply of novel bioavailable nitrogen for the food web. However, the fate of the nitrogen fixed by cyanobacteria remains unresolved, as does its importance for secondary production in the Baltic Sea. Here, we synthesize recent experimental and field studies providing strong empirical evidence that cyanobacterial nitrogen is efficiently assimilated and transferred in Baltic food webs via two major pathways: directly by grazing on fresh or decaying cyanobacteria and indirectly through the uptake by other phytoplankton and microbes of bioavailable nitrogen exuded from cyanobacterial cells. This information is an essential step toward guiding nutrient management to minimize noxious blooms without overly reducing secondary production, and ultimately most probably fish production in the Baltic Sea.

    Arsenic occurs as a persistent constituent in many of the chemical weapons dumped into the Baltic Sea; it can be used as an indicator of leakage and dispersal of released munitions to the marine environment. Total arsenic was analysed in sediment samples taken from the Lithuanian economic zone in the Baltic Sea, which included samples from the chemical munitions dumpsite in the Gotland Basin and national monitoring stations in the southeastern Baltic Sea. Arsenic concentrations in sediments ranged from 1.1 to 19.0 mg kg -1 , with an average of 3.4 mg kg -1 . Although there was evidence of slightly elevated arsenic content in sediments near the weapons dumpsite, arsenic concentrations were nevertheless quite low relative to other investigations in the Baltic and North Seas. - Arsenic concentrations in sediments near chemical weapons dumpsites were only slightly elevated

  17. Transborder corporate integration in the Baltic Sea Region

    Directory of Open Access Journals (Sweden)

    Kuznetsov Alexei

    2012-03-01

    Full Text Available The paper examines flows of foreign direct investment within the Baltic region. The author demonstrates close investment ties among the EU members, which are of special importance for Estonia, Latvia and Lithuania. Transborder corporate integration in the region is characterized by significant imbalances. In many aspects, it can be viewed as Sweden’s economic expansion or development of domestic markets for northern European companies. Although many German, Polish and Russian companies are involved in corporate integration in the Baltic region, other vectors of their foreign economic relations are still more important for them. As a result, the integration of Russian business in the Baltic part of the European integration area is still rather weak despite Russia’s considerable foreign direct investment in the Baltic States.

  18. Size matters: relationships between body size and body mass of common coastal, aquatic invertebrates in the Baltic Sea

    Directory of Open Access Journals (Sweden)

    Johan Eklöf

    2017-01-01

    Full Text Available Background Organism biomass is one of the most important variables in ecological studies, making biomass estimations one of the most common laboratory tasks. Biomass of small macroinvertebrates is usually estimated as dry mass or ash-free dry mass (hereafter ‘DM’ vs. ‘AFDM’ per sample; a laborious and time consuming process, that often can be speeded up using easily measured and reliable proxy variables like body size or wet (fresh mass. Another common way of estimating AFDM (one of the most accurate but also time-consuming estimates of biologically active tissue mass is the use of AFDM/DM ratios as conversion factors. So far, however, these ratios typically ignore the possibility that the relative mass of biologically active vs. non-active support tissue (e.g., protective exoskeleton or shell—and therefore, also AFDM/DM ratios—may change with body size, as previously shown for taxa like spiders, vertebrates and trees. Methods We collected aquatic, epibenthic macroinvertebrates (>1 mm in 32 shallow bays along a 360 km stretch of the Swedish coast along the Baltic Sea; one of the largest brackish water bodies on Earth. We then estimated statistical relationships between the body size (length or height in mm, body dry mass and ash-free dry mass for 14 of the most common taxa; five gastropods, three bivalves, three crustaceans and three insect larvae. Finally, we statistically estimated the potential influence of body size on the AFDM/DM ratio per taxon. Results For most taxa, non-linear regression models describing the power relationship between body size and (i DM and (ii AFDM fit the data well (as indicated by low SE and high R2. Moreover, for more than half of the taxa studied (including the vast majority of the shelled molluscs, body size had a negative influence on organism AFDM/DM ratios. Discussion The good fit of the modelled power relationships suggests that the constants reported here can be used to quickly estimate

  7. Nord stream: not just a pipeline. An analysis of the political debates in the Baltic Sea region regarding the planned gas pipeline from Russia to Germany

    Energy Technology Data Exchange (ETDEWEB)

    Whist, Bendik Solum

    2008-11-15

    This report is an analysis of the planned gas pipeline from Russia to Germany through the Baltic Sea known as Nord Stream. Although not yet realised, the project has, since its birth, been the subject of harsh criticism and opposition by a significant number of states that consider themselves affected by the pipeline. Whereas the Baltic States and Poland have interpreted the pipeline as a politically motivated strategy that will increase Russia's leverage on them and threaten their energy security, the debate in Sweden was at first mostly concerned with the prospect of increased Russian military presence in the Swedish Exclusive Economic Zone. The potential environmental impact of the pipeline has been, and continues to be, an overarching concern shared by all the littoral states of the Baltic Sea. Proponents of Nord Stream, most notably Germany, Russia and the Nord Stream consortium, have largely dismissed the concerns as unwarranted and argue that the pipeline is a common European project that all EU-members should embrace, as it will provide much-needed gas to an increasingly energy-thirsty union. This report is an extensive study of the divergent attitudes and debates that have surged in the region regarding Nord Stream, and the aim is to provide plausible explanations as to why the interpretations of the project have been so different in the various states. The report is based on a variety of sources, including several first-hand interviews with researchers and government officials in the Baltic Sea region. (author). refs.,fig.,tabs

    The Baltic Sea is a seasonally ice-covered, marginal sea, situated in central northern Europe. It is an essential waterway connecting highly industrialised countries. Because ship traffic is intermittently hindered by sea ice, the local weather services have been monitoring sea ice conditions for decades. In the present study we revisit a historical monitoring data set, covering the winters 1960/1961. This data set, dubbed Data Bank for Baltic Sea Ice and Sea Surface Temperatures (BASIS) ice, is based on hand-drawn maps that were collected and then digitised 1981 in a joint project of the Finnish Institute of Marine Research (today Finish Meteorological Institute (FMI)) and the Swedish Meteorological and Hydrological Institute (SMHI). BASIS ice was designed for storage on punch cards and all ice information is encoded by five digits. This makes the data hard to access. Here we present a post-processed product based on the original five-digit code. Specifically, we convert to standard ice quantities (including information on ice types), which we distribute in the current and free Network Common Data Format (NetCDF). Our post-processed data set will help to assess numerical ice models and provide easy-to-access unique historical reference material for sea ice in the Baltic Sea. In addition we provide statistics showcasing the data quality. The website www.baltic-ocean.org hosts the post-prossed data and the conversion code. The data are also archived at the Data Publisher for Earth & Environmental Science PANGEA (doi:10.1594/PANGEA.832353).

  10. On Russian/Nordic Investment Competition in the Baltic States

    Directory of Open Access Journals (Sweden)

    Olenchenko Vladimir

    2015-06-01

    Full Text Available The researchers often overlook the relationships between Russian and Nordic investment capital; and even less attention is paid to studying the competition between the two. Yet this subject can be of particular relevance to the areas that are geographically, historically and culturally close to both Russia and the Nordic countries. Thus, the aim of this article is to understand how the competition between Russian and Nordic capital investment is played out in the Baltic States. The study discusses the principles of Russian and Nordic investment in the Baltic, and suggests ways to regulate these relations. To this end, we compare the investment conditions created in the Baltic States for both Russian and Nordic investors. The analysis shows that most of the Baltic market is controlled by the Nordic capital, which blocks the arrival of Russian investment to the Baltic States. With a nod to a number of previous studies, the authors of this article suggest some adjustments to the theory of foreign direct investment. The study will be also of practical interest to those Russian investors who are seeking entry points to the Baltic markets.

  11. Forecasting Actions of Baltic elites: A Scenario Approach

    Directory of Open Access Journals (Sweden)

    Smirnov Vadim A.

    2016-09-01

    Full Text Available This paper provides an overview of different approaches to forecasting the future of the three Baltic States. The author’s theoretical approach to studying Baltic elites is used to forecast changes in the action models of the Baltic elites. The article stresses the scarcity of internal political processes in the Baltics. However, a significant number of scenarios focusing on military aspects in the Baltics have recently been published. The author distinguishes between inertia, confrontation, and cooperation scenarios and examines their prerequisites and possible consequences. The scenarios are developed based on an analysis of geographic, economic, and political factors. The decisive factor is a state-controlled foreign policy, which is affected by the international situation as well as relations between the state and the external resources exploited by political elites. The paper contributes to the general debate about the factors of political development and the role of political elites in it. The author pr ovides additional material for analysing possible developments in the domestic policies of the Baltic States in view of external factors.

  12. Islamic Diffusion in the Baltics: The Fruit of European Multiculturalism

    Directory of Open Access Journals (Sweden)

    Gladkiy Yu. N.

    2017-10-01

    Full Text Available This article considers Western Europe as a principal centre that has been attracting migrants over recent decades, primarily, in the aftermath of the Arab Spring. The Baltic region states are chosen for demonstration. Although they have different proportions of Muslim immigrants, Muslim diasporas are the most numerous and rapidly growing ones in the Baltics. Undoubtedly, Muslim communities across the region enjoy certain similarities. The differences they have are explained, among other factors, by national policies towards migrant integration. This article aims to identify the features of Muslim migration to the Baltic States in the aftermath of the Arab Spring. The authors analyse the timeline of Muslim immigration to the Baltic region. It is stressed that, despite current difficulties, Germany and Finland are more successful in integrating immigrants than, for instance, Sweden and Denmark. Just like other Western European countries, the Baltic States have not developed a conceptual framework for their migration and integration policies towards Muslim immigrants. The authors describe possible Muslim integration scenarios — the Singaporean and Palestinian ones, simulation, and confrontation. Given their apparent conscientious refusal to adapt and integrate migrants, the Baltic States are most likely to face the Palestinian scenario.

  13. Swedish earthquakes and acceleration probabilities

    International Nuclear Information System (INIS)

    Slunga, R.

    1979-03-01

    A method to assign probabilities to ground accelerations for Swedish sites is described. As hardly any nearfield instrumental data is available we are left with the problem of interpreting macroseismic data in terms of acceleration. By theoretical wave propagation computations the relation between seismic strength of the earthquake, focal depth, distance and ground accelerations are calculated. We found that most Swedish earthquake of the area, the 1904 earthquake 100 km south of Oslo, is an exception and probably had a focal depth exceeding 25 km. For the nuclear power plant sites an annual probability of 10 -5 has been proposed as interesting. This probability gives ground accelerations in the range 5-20 % for the sites. This acceleration is for a free bedrock site. For consistency all acceleration results in this study are given for bedrock sites. When applicating our model to the 1904 earthquake and assuming the focal zone to be in the lower crust we get the epicentral acceleration of this earthquake to be 5-15 % g. The results above are based on an analyses of macrosismic data as relevant instrumental data is lacking. However, the macroseismic acceleration model deduced in this study gives epicentral ground acceleration of small Swedish earthquakes in agreement with existent distant instrumental data. (author)

  14. Energy efficiency in Swedish industry

    Zhang, Shanshan; Lundgren, Tommy; Zhou, Wenchao

    2016-01-01

    This paper assesses energy efficiency in Swedish industry. Using unique firm-level panel data covering the years 2001–2008, the efficiency estimates are obtained for firms in 14 industrial sectors by using data envelopment analysis (DEA). The analysis accounts for multi-output technologies where undesirable outputs are produced alongside with the desirable output. The results show that there was potential to improve energy efficiency in all the sectors and relatively large energy inefficiencies existed in small energy-use industries in the sample period. Also, we assess how the EU ETS, the carbon dioxide (CO_2) tax and the energy tax affect energy efficiency by conducting a second-stage regression analysis. To obtain consistent estimates for the regression model, we apply a modified, input-oriented version of the double bootstrap procedure of Simar and Wilson (2007). The results of the regression analysis reveal that the EU ETS and the CO_2 tax did not have significant influences on energy efficiency in the sample period. However, the energy tax had a positive relation with the energy efficiency. - Highlights: • We use DEA to estimate firm-level energy efficiency in Swedish industry. • We examine impacts of climate and energy policies on energy efficiency. • The analyzed policies are Swedish carbon and energy taxes and the EU ETS. • Carbon tax and EU ETS did not have significant influences on energy efficiency. • The energy tax had a positive relation with energy efficiency.

  15. 210Pb dating of Baltic Sea sediments

    International Nuclear Information System (INIS)

    Gellermann, R.

    1990-01-01

    The paper reports on the results of 210 Pb measurement in sediment cores from the Baltic Sea. The models used for the interpretation are derived and discussed. In general, the sedimentation parameters calculated with different models are consistent. However, parameters of cores independently taken on same partly show clearly differing values. The reasons of this observation have to be analysed by further studies. An essential problem considered in this paper is the dating of disturbed sediments. The use of such cores for the reconstruction of the input history of chemical indicators requires a deconvolution of data. The response function necessary for this procedure can be derived from 210 Pb measurements. The results of such a reconstruction considerably differ from those obtained by conventional dating models. The analysis of the measuring uncertainty of the indicator (e.g. lead) in the deconvolution procedure unveals the limits of the method and prevents it from overinterpretation. (orig.) [de

The GTC index is a useful instrument for rational global talent management when using the EU structural funds, in- tersectorial distributing of limited resources for more rational development of labour & vocational skills, for evaluating the innovation and talent growth determi- nants.

    Full Text Available This overview presents in detail the state of knowledge of the abilities of various components of the Baltic Sea environment to accumulate trace elements and radionuclides. Particular components of the Baltic ecosystem (abiotic and biotic are considered as potential monitors of pollutants. The use of seaweeds, e.g. Fucus vesiculosus or Zostera marina is recommended, also molluscs, e.g. Mytilus edulis, for biomonitoring surveys of metal pollutants and radionuclides in the Baltic Sea. However, several requirements need to be met if results are to be reliable. Since metal levels and radionuclide activities in the growing tips of F. vesiculosus reflect exclusively the levels of their dissolved species in the ambient seawater, this alga is very useful for monitoring dissolved species of metal pollutants and radioisotopes in the Baltic ecosystem. In contrast, M. edulis, a filter feeder is an appropriate tool for monitoring trace elements occurring in both chemical forms, i.e. dissolved and suspended species. Therefore, full information on the bioavailability and toxicity of heavy metals (depending on their chemical speciation as pollutants of the Baltic Sea can be obtained if at least two biomonitoring organisms are applied simultaneously, e.g. F. vesiculosus and M. edulis. Moreover, the data matrix can be interpreted more accurately if not only trace element but also macroelement concentrations (Ca, Mg, Na, K in these two representatives of Baltic phyto- and zoobenthos are taken into consideration; this point requires special attention. Two coastal species of fish, i.e. Zoarces viviparus and Perca fluviatilis, are good biomonitors of metallic contaminants, so their use as sentinels is recommended. The budgets of chemical elements and the ecological status of the Baltic Sea are presented. Several "black spots", e.g. large estuaries and seaport towns, heavily polluted by trace elements, are identified in the Baltic Sea and other enclosed seas such the

    2014-05-01

    In this study, retrievals of the medium resolution imaging spectrometer (MERIS) reflectances and water quality products using four different coastal processing algorithms freely available are assessed by comparison against sea-truthing data. The study is based on a pair-wise comparison using processor-dependent quality flags for the retrieval of valid common macro-pixels. This assessment is required in order to ensure the reliability of monitoring systems based on MERIS data, such as the Swedish coastal and lake monitoring system (http://vattenkvalitet.se). The results show that the pre-processing with the Improved Contrast between Ocean and Land (ICOL) processor, correcting for adjacency effects, improves the retrieval of spectral reflectance for all processors. Therefore, it is recommended that the ICOL processor should be applied when Baltic coastal waters are investigated. Chlorophyll was retrieved best using the FUB (Free University of Berlin) processing algorithm, although overestimations in the range 18-26.5%, dependent on the compared pairs, were obtained. At low chlorophyll concentrations (definition at relatively low chlorophyll concentrations in the presence of high CDOM attenuation.

    This report includes the main results from the Fifth Pollution Load Compilation abbreviated PLC-5. It includes quantified annual waterborne total loads (from rivers, unmonitored and coastal areas as well as direct point and diffuse sources discharging directly to the Baltic Sea) from 1994 to 2008 to provide a basis for evaluating any decreasing (or increasing) trends in the total waterborne inputs to the Baltic Sea. Chapter 1 contains the objectives of PLC and the framework on classification of inputs and sources. Chapter 2 includes a short description of the Baltic Sea catchment area, while the methods for quantification and analysis together with quality assurance topics are briefly introduced in Chapter 3. More detailed information on methodologies is presented in the PLC-5 guidelines (HELCOM 2006). Chapter 4 reports the total inputs to the Baltic Sea of nutrients and selected heavy metals. Furthermore, the results of the quatification of discharges and losses of nitrogen and phosphorus from point and diffuse sources into inland surface waters within the Baltic Sea catchment area (source-oriented approach or gross loads) as well as the total load to the maritime area (load-oriented approarch or net loads) in 2006 are shown. Typically, results are presented by country and by main Baltic Sea sub-region. In Chapter 5, flow normalization is introduced and the results of trend analyses on 1994-2008 time series data on total waterborne loads of nitrogen and phosphorus are given together with a first evaluation of progress in obtaining the provisional reduction targets by country and by main Baltic Sea sub-region. Chapter 6 includes discussion of some of the main conclusions and advice for future PLCs. The annexes contain the flow-normalized annual load data and figures and tables with results from the PLC-5.

    Full text: The Swedish mutation research programme in barley began about 50 years ago and has mainly been carried out at Svaloev in co-operation with the institute of Genetics at the University of Lund. The collection has been produced from different Swedish high-yielding spring barley varieties, using the following mutagens: X-rays, neutrons, several organic chemical compounds such as ethyleneimine, several sulfonate derivatives and the inorganic chemical mutagen sodium azide. Nearly 10,000 barley mutants are stored in the Nordic Gene Bank and documented in databases developed by Udda Lundquist, Svaloev AB. The collection consists of the following nine categories with 94 different types of mutants: 1. Mutants with changes in the spike and spikelets; 2. Changes in culm length and culm composition; 3. Changes in growth types; 4. Physiological mutants; 5. Changes in awns; 6. Changes in seed size and shape; 7. Changes in leaf blades; 8. Changes in anthocyanin and colour; 9. Resistance to barley powdery mildew. Barley is one of the most thoroughly investigated crops in terms of induction of mutations and mutation genetics. So far, about half of the mutants stored at the Nordic Gene Bank, have been analysed genetically; They constitute, however, only a minority of the 94 different mutant types. The genetic analyses have given valuable insights into the mutation process but also into the genetic architecture of various characters. A number of mutants of two-row barley have been registered and commercially released. One of the earliest released, Mari, an early maturing, daylength neutral, straw stiff mutant, is still grown in Iceland. The Swedish mutation material has been used in Sweden, but also in other countries, such as Denmark, Germany, and USA, for various studies providing a better understanding of the barley genome. The collection will be immensely valuable for future molecular genetical analyses of clone mutant genes. (author)

    Four watersheds, each characterized by a major resource use were selected for the study: The Vistula River in Poland—agriculture; the Dalälven River in Sweden—forestry; the Archipelago Sea in Sweden, Finland, Estonia—tourism; and the Lake Peipsi in Estonia/Russia—fisheries/agriculture. The main objective was to examine the reactions of particular ecosystems within the Baltic Sea drainage area, and to assess sustainability conditions on the regional level. The degree of sustainability and impact on the Baltic Sea were investigated through workshops and seminars in the areas. Overviews of environmental and socio-economic conditions were succinctly summarized in commissioned papers. Interventions by and discussions with scholars, sector experts, administrators and stakeholders of the various sites laid the foundation for conceptualizing the interaction of natural and human forces for each case. The project was able to draw quite a number of conclusions, summarized as the following lessons learnt. In the Vistula Region, nutrient emissions have levelled off but shortage of freshwater is critical. Forestry in the Dalälven watershed is largely environmental-friendly, except for fragmentation of the landscape and its negative impact on biodiversity. In the Archipelago area a former low-energy community has been replaced by a leisure time society. Different types of tourism is developing, but despite this variety, an improved integration of ecological properties with socio-economic patterns is required in order to build a sustainable, living Archipelago. The lake Peipsi basin and the surrounding area suffer both from problems of resource management and economic backwardness. Parts of the local economy has lost access to the one time large Soviet market, although the Estonian side has apparently benefited from present economic growth. To cope with the division of the lake, a regime for trans-national management is unfolding. It is based on both informal and, to an

    Marine Science and Technology has been traditionally a male-dominated research field, with a significant lack of women in leadership positions. However, the whole intellectual capacity of men and women alike are needed to create innovative solutions for the sustainable use of marine resources in the face of major global challenges for the development of the marine environment. The EU-funded project, Baltic Gender (GA No. 710363), responds to this need for creating policies and implementing measures at the institutional level with the aim of harvesting the full human capital for the needs of marine research. The main goal of Baltic Gender is to help reduce gender segregation and gender inequalities in Marine Science and Technology. To this end, eight partner institutions from five countries in the Baltic Sea region (Estonia, Finland, Germany, Lithuania and Sweden) came together for the exchange of institutional practices as well as for the transfer of knowledge from institutions/countries leading in gender equality to those following. Baltic Gender will sow the seeds for long-lasting institutional practices by initiating schemes and strategies that promote gender equality in the partner institutions. These include, for instance: the founding of grass-root networks that support the career advancement of women; creating strategies for better reconciliation of work and family life of women and men; the review and improvement of institutional policies and practices with regard to gender balance, fairness and transparency; development of a method protocol for incorporating gender analysis into research projects or programmes of Marine Science and Technology; initiating gender focused training and mentoring in or across all partner institutions. The project will support the implementation of Gender Equality Plans (GEPs), which consist of a set of actions an institution commits to in order to identify any existing gender bias and to implement strategies to advance gender

    2011-10-01

    We address possibilities of minimising environmental risks using statistical features of current-driven propagation of adverse impacts to the coast. The recently introduced method for finding the optimum locations of potentially dangerous activities (Soomere et al. in Proc Estonian Acad Sci 59:156-165, 2010) is expanded towards accounting for the spatial distributions of probabilities and times for reaching the coast for passively advecting particles released in different sea areas. These distributions are calculated using large sets of Lagrangian trajectories found from Eulerian velocity fields provided by the Rossby Centre Ocean Model with a horizontal resolution of 2 nautical miles for 1987-1991. The test area is the Gulf of Finland in the northeastern Baltic Sea. The potential gain using the optimum fairways from the Baltic Proper to the eastern part of the gulf is an up to 44% decrease in the probability of coastal pollution and a similar increase in the average time for reaching the coast. The optimum fairways are mostly located to the north of the gulf axis (by 2-8 km on average) and meander substantially in some sections. The robustness of this approach is quantified as the typical root mean square deviation (6-16 km) between the optimum fairways specified from different criteria. Drastic variations in the width of the `corridors' for almost optimal fairways (2-30 km for the average width of 15 km) signifies that the sensitivity of the results with respect to small changes in the environmental criteria largely varies in different parts of the gulf.

    Varying redox conditions may affect the occurrence and concentrations of certain radionuclides in the surface layers of sediments and in near-bottom waters by causing remobilization of radionuclides from surface sediments to the overlying water and their settling back into the sediment. In recent decades about 70.000 km 2 of the sea bottom in the deepest part of the Baltic Sea (about 19% of its total area) have withstood almost continuous anoxic conditions; thus, it is important to know to what extent depletion of oxygen can affect the behaviour of these radionuclides in near-bottom waters. The aim of the project was to resolve the above question in a coastal basin periodically undergoing anoxic conditions. Radioecological processes in sediments and in near-bottom water under varying redoxconditions were studied in the deep area of the Haestholmsfjaerden Bay in Loviisa (eastern Gulf of Finland) in 1995-1996. The Haestholmsfjaerden Bay is a semienclosed basin between the mainland and the archipelago and is connected with the open Gulf of Finland only through narrow, shallow sounds: In 1995, total depletion of oxygen occurred in the hypolimnion of Haestholmsfjaerden Bay during 2 periods in late summer and autumn. In 1996, oxygen conditions were the worst ever observed in the Haestholmsfjaerden deep. During early autumn anoxic conditions prevailed for more than 1 month in the near-bottom water. The highest total phosphorus and total nitrogen concentrations in the near-bottom water during these periods were 20- and 4- fold compared with the corresponding values in surface water. According to the results obtained in this project, remobilization of 137 Cs and 239,240 Pu from sediments to near-bottom water is negligible or non-existent in the Haestholmsfjaerden deep. If it does occur, however, it may be so slight that it is not possible to observe with the methods used in this study. Although the anoxic periods are quite short in the Haestholmsfjaerden deep, they are of

    Full Text Available The article analyses the process of the Baltic states’ accession to the eurozone and examines the consequences of their adoption of the euro currency. Although Estonia, Latvia and Lithuania joined the eurozone in different years, they share a number of common features in terms of both their accession process and presence in the euro area. The article consists of three parts – the first surveys the Baltic states’ conformity with the convergence criteria and the second examines the effects that can be observed in the economies of the three Baltic countries after accession. The third part contains a comparative analysis of actual inflation versus perceived inflation index seen over the three years spanning the periods before, during and after the adoption of the euro. For this purpose, calculations of simplified perceived inflation indices in the Baltic States were compiled and compared against actual inflation. The differences across the Baltic states between the perceived inflation index and real inflation were similar to those in Austria and Germany during these countries’ accession to the euro zone.

    Full Text Available Globalisation is creating a global culinary space where culinary traditions of different countries interact and compete. The author sets out to explore characteristic features of the culinary space of nine Baltic States as part of the global culinary space. The author uses empirical data on the number of restaurants serving different national cuisines in the main cities of the region. The Baltic culinary space incorporates the world’s leading cuisines (Italian, Japanese, Chinese, etc. as well as the local cuisines of the BSR countries. The world’s leading cuisines prove to be more influential in the region than the local ones. Some countries of the Baltic Sea region (Russia, Poland, Sweden, Latvia, and Denmark have culinary sovereignty, since their residents prefer national cuisines. In some other countries of the region (Finland, Estonia, and Lithuania, the public favours the world’s leading cuisines — Italian, Japanese and American — over the local ones. The non-capital Baltic cities of Poland and Germany, as well as St. Petersburg, display a greater sense of culinary patriotism than Warsaw, Berlin, and Moscow respectively. This article attempts to explore the features of the Baltic culinary space. The author considers the environmental and socio- historical factors key determinants of the countries’ cuisines.

    2018-05-01

    Full Text Available The authors employ geopolitical analysis to identify the core characteristics of NATO’s current policy towards the Baltic Sea region. After the demise of the Soviet Union, the region was considered as one of the safest in terms of military security. However, in the aftermath of the Ukraine crisis, the region has witnessed a growing tension in relations between NATO and the Russian Federation. A comparative analysis of NATO’s official documents on the Baltics shows that the chief pretext for increased military presence in the region is the alleged need to defend the Baltic states from the Russian threat. Special attention is paid to the attempts of Western military strategists to encourage the neutral Nordic states — Sweden and Finland — to accede to NATO. This would lead to the organisation’s northern enlargement. The current situation suggests that to ease tension in the Baltic Sea region Russia has not only to respond adequately to emerging military threats but also to launch an awareness campaign to explain its position and dispel the myth about Russia preparing to start a hybrid war against the Baltic States.

    Monitoring of radioactive substances in the Baltic Sea was continued within the framework of the Finnish national monitoring programme. Samples of sea water, bottom sediment and fish were collected for radionuclide analyses. All samples were analysed for gamma-emitting radionuclides and partly also for 90 Sr and transuranic elements. The activity concentrations of 137 Cs were about 120 Bq/m 3 in the surface water of the Bothnian Bay, 220-320 Bq/m 3 in the Bothnian Sea, 120-230 Bq/m 3 in the Gulf of Finland and 150-170 Bq/m 3 in the Baltic Proper. In the open Gulf of Finland and Bothnian Sea the 137 Cs concentrations of surface water were about 20 and 55 % of the maximum values in 1986. The total amounts of 137 Cs in bottom sediments ranged from 1700 to 16000 Bq/m 2 . In the Gulf of Bothnia and Gulf of Finland the total amounts of 137 Cs were about 5-6 times higher in 1988 than before the Chernobyl accident and 3 times higher in the northern Baltic Proper. The 137 Cs concentrations in Baltic herring ranged from 20 to 37 Bq/kg fresh weight and in pike from 38 to 160 Bq/kg fresh weight, the maximum values being in samples supplied from the Vaasa archipelago. The internal radiation dose to Finnish people caused by the consumption of Baltic Sea fish in 1988 was about 0.009mSv. (orig.)

    1990-06-01

    More than 200 earthquakes in the Baltic Shield area in the size range ML 0.6-4.5 have been studied by dense regional seismic networks. The analysis includes focal depths, dynamic source parameters, and fault plane solutions. In southern Sweden a long part of the Protogene zone marks a change in the seismic activity. The focal depths indicate three crustal layers: Upper crust (0-18 km in southern Sweden, 0-13 km in northern Sweden), middle crust down to 35 km, and the quiet lower crust. The fault plane solutions show that strike-slip is dominating. Along the Tornquist line significant normal faulting occurs. The stresses released by the earthquakes show a remarkable consistency with a regional principle compression N60W. This indicates that plate-tectonic processes are more important than the land uplift. The spatial distribution is consistent with a model where the earthquakes are breakdowns of asperities on normally stably sliding faults. The aseismic sliding is estimated to be 2000 times more extensive than the seismic sliding. Southern Sweden is estimated to deform horizontally at a rate of 1 mm/year or more. (orig.)

    Full Text Available Innovative activity is carried out at three levels — those of the state, region and a company or a university. This article considers the level of development of knowledge-based economy in Germany, Denmark, Sweden, Finland, Estonia, Latvia, Lithuania, and Poland at each of the three levels, as well as descripes the spatial differentiation of innovative activity within the Baltic region. The analysis is done on the basis of national and international research, as well as statistical data on the intensity of research and development, structure of research expenditure, human capital in the field of advanced technologies, and the methods of institutional support for innovative activity. The authors characterise the role of business, university, and authorities — which constitute the «triple helix» — in national innovative systems. The article also analyses such important factors as the intensity of research and development, the share of employees in the field of advanced technologies, and the methods of public support. Examples of private-public infrastructure for the implementation of innovative projects are offered.

  9. Dioxins and dioxin-like PCBs in fish in general and in particular from Baltic Sea

    Commission Regulation No 466/2001 establishes maximum levels for dioxins in foodstuffs, foreseeing to review the maximum levels by 31 December 2006 and to include dioxin-like PCBs in the levels to be set. Fish is known to accumulate dioxins and dioxin related compounds in the lipid phase of their tissue. To collect information of the actual contamination levels in fish species on the German market, samples were taken from fishing grounds important for the supply and in particular from the Baltic Sea. Sampling concentrates on fish species with higher fat content like mackerel (Scomber scombrus), salmon (Salmo salar), trout (Oncorhynchus mykiss), red fish (Sebastes sp.) and herring (Clupea harengus), because lean fish species are known to be less contaminated. Herring is the most important fat fish species for the German fish processing industry with a market share of 19% in 2001. The annual demand is approximately 149.000 t. Herring and other fish species accumulate PCDD/Fs with increasing age and dioxin levels in the edible part of eastern Baltic herring exceeds the maximum limit of 4 ng WHOPCDD/ F-TEQ/kg wet weight (w.w.) at ages of 4 - 6 years, corresponding to sizes of approximately 17 - 18 cm and a weight of 40 g, respectively. Hence Isosaari recommended to use preferably young fish from this area for human consumption. However, the German herring industry is based on the processing of large herring with a minimum weight of > 85g up to 250g. Therefore our interest focused on herring sizes of potential interest for the German processing industry. Samples were collected in September 1999 within two weeks covering an area from the Skagerrak to the Coast of Latvia. Additionally the contamination levels in sprat (Sprattus sprattus), flounder, brown trout (Salmo trutta) and in spring spawning herring from commercial landings around the area of Ruegen have been analysed.

  10. Modeling pathways of riverine nitrogen and phosphorus in the Baltic Sea

    A better understanding of the fate of nutrients entering the Baltic Sea ecosystem is an important issue with implications for environmental management. There are two sources of nitrogen and phosphorus: riverine input and atmospheric deposition. In the case of nitrogen, the fixation of dinitrogen by diazotrophic bacteria represents a third source. From an analysis of stable nitrogen isotope ratios it was suggested that most of the riverine nitrogen is sequestered in the coastal rim, specifically along the southern Baltic Sea coast with its coarse sediments, whereas nitrogen from fixation dominates the central basins. However, pathways of nutrients and timescales between the input of the nutrients and their arrival in different basins are difficult to obtain from direct measurements. To elucidate this problem, we use a source attribution technique in a three-dimensional ecosystem model, ERGOM, to track nutrients originating from various rivers. An “age” variable is attributed to the marked elements to indicate their propagation speeds and residence times. In this paper, we specifically investigate the spreading of nitrogen and phosphorus from the riverine discharges of the Oder, Vistula, Neman and Daugava. We demonstrate which regions they are transported to and for how long they remain in the ecosystem. The model results show good agreement with source estimations from observed δ15N values in sediments. The model results suggest that 95% of nitrogen is lost by denitrification in sediments, after an average time of 1.4 years for riverine nitrogen. The residence time of riverine phosphorus is much longer and exceeds our simulated period of 35 years.

    Between 1975 and 1984 the measurements of concentrations of Sr-90, Cs-137, Pu-239, 240, H-3, K-40, Ra-226, Ta-232, Ti, Mn, Fe, Zn, Rb, Pb, Cd and Sr have been determined in various components of the Baltic Sea. The radionuclides were determined by radiochemical and gamma spectroscopic methods, and the stable nuclides by differential pulse anodic stripping voltametry and by energy dispersive X-ray fluorescence. The concentrations of Cs-137 in the Baltic seawater was up to 7 times lower than in the Northern sea but 20 times higher than in the water from the Polish rivers. The concentrations of Cs-137 were related to the salinity. In sediments Sr-90 levels were 1-2 orders of magnitude lower than those of other nuclides. The radioactivity of fish was found 1 order of magnitude higher in the Baltic than in Polish lakes and rivers. (author)

    Long-term radionuclides volume activity (v.a.) monitoring (1976-1990) data showed that measurement results obtained in steady observation station give reliable information of the coastal area of the Baltic sea radioactive equilibrium between atmosphere and surface water was observed in the coastal zone. Chernobyl Power Plant accident influenced upon the Baltic sea coastal water by radionuclides 137 Cs and 144 Ce. Radionuclide 90 Sr volume activity was practically unchangerable. The mechanism of radionuclides fallout from atmosphere are various. lt can be illustrated by 137 Cs and 144 Ce a.v. structure field variations in open sea and coastal zone near Juodkrante. The Baltic sea inhomogeneous contamination by radionuclide 137 Cs in 1988-1990 leads to equalization of 137 Cs v.a. in the surface waters and it causes v.a. increase in coastal waters. (author)

    Full Text Available In this paper we focus on the structure and territorial borders of the Baltic Sea region, and examine the key structural elements of the transnational territorial transport system. In this respect, we clarify some terms used in transport geography. For the first time the transport system gets territorially localized, which allows for a broad range of new studies of transnational transportation in the Baltic Sea area. We also identify the main principles of development and operation of international territorial transport systems and present them taking the Baltic Sea region as an example. Our findings, we hope, will have a great practical application for researchers of transport geography, especially those studying international logistics.

  16. Factors affecting metal and radionuclide pollution in the Baltic sea

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available External pollution load in the Baltic Sea originates from urban, agricultural and industrial sources. Emissions of heavy metals have decreased substantially in the catchment area but the temporal trends are not always significant and differ with sample, area and pollutant. The most significant source of anthropogenic radioactivity in the Baltic Sea is fallout from the Chernobyl accident in 1986. Many factors affect the future development of pollutant concentrations including anthropogenic emissions, political decisions and changes in salinity, temperature and water currents, in eutrophication and oxygen status, in fisheries and in atmospheric deposition of pollutants. Large scale changes like eutrophication and climate change affect ecosystems in many ways, directly and indirectly, causing biological and abiotic effects. These factors are interrelated and difficult to predict. Measures aiming to enhance the ecological status of the Baltic Sea will certainly give positive results but this will take at least several decades.

The correlations between the changes in the shoreline and the dune toe range from -0.4 to 0.8. It is most often the case that the dune toe is stable while the shoreline moves. Consistent cross-shore migration is slightly more likelyto happen than the divergent or convergent movements of both lines. Shoreline retreat and advance attain respective rates of 0.7 m day-1 and 0.4 m day-1. Deep-water wave energy of about 50 kJ m-1 constitutes the boundary between shore accumulation and erosion.

  20. Biological Soil Crusts from Coastal Dunes at the Baltic Sea: Cyanobacterial and Algal Biodiversity and Related Soil Properties.

    Biological soil crusts (BSCs) are known as "ecosystem-engineers" that have important, multifunctional ecological roles in primary production, in nutrient and hydrological cycles, and in stabilization of soils. These communities, however, are almost unstudied in coastal dunes of the temperate zone. Hence, for the first time, the biodiversity of cyanobacterial and algal dominated BSCs collected in five dunes from the southern Baltic Sea coast on the islands Rügen and Usedom (Germany) was investigated in connection with physicochemical soil parameters. The species composition of cyanobacteria and algae was identified with direct determination of crust subsamples, cultural methods, and diatom slides. To investigate the influence of soil properties on species composition, the texture, pH, electrical conductivity, carbonate content, total contents of carbon, nitrogen, phosphorus, and the bioavailable phosphorus-fraction (PO4 (3-)) were analyzed in adjacent BSC-free surface soils at each study site. The data indicate that BSCs in coastal dunes of the southern Baltic Sea represent an ecologically important vegetation form with a surprisingly high site-specific diversity of 19 cyanobacteria, 51 non-diatom algae, and 55 diatoms. All dominant species of the genera Coleofasciculus, Lyngbya, Microcoleus, Nostoc, Hydrocoryne, Leptolyngbya, Klebsormidium, and Lobochlamys are typical aero-terrestrial cyanobacteria and algae, respectively. This first study of coastal sand dunes in the Baltic region provides compelling evidence that here the BSCs were dominated by cyanobacteria, algae, or a mixture of both. Among the physicochemical soil properties, the total phosphorus content of the BSC-free sand was the only factor that significantly influenced the cyanobacterial and algal community structure of BSCs in coastal dunes.

  1. The Baltic Sea natural long-term variability of salinity

    Schimanke, Semjon; Markus Meier, H. E.

    2015-04-01

    The Baltic Sea is one of the largest brackish sea areas of the world. The sensitive state of the Baltic Sea is sustained by a fresh-water surplus by river discharge and precipitation on one hand as well as inflows of highly saline and oxygen-rich water masses from the North Sea on the other. Major inflows which are crucial for the renewal of the deep water occur very intermittent with a mean frequency of approximately one per year. Stagnation periods (periods without major inflows) lead for instance to a reduction of oxygen concentration in the deep Baltic Sea spreading hypoxic conditions. Depending on the amount of salt water inflow and fresh-water supply the deep water salinity of the Baltic Sea varies between 11 to 14 PSU on the decadal scale. The goal of this study is to understand the contribution of different driving factors for the decadal to multi-decadal variability of salinity in the Baltic Sea. Continuous measurement series of salinity exist from the 1950 but are not sufficiently long for the investigation of long-term fluctuations. Therefore, a climate simulation of more than 800 years has been carried out with the Rossby Center Ocean model (RCO). RCO is a biogeochemical regional climate model which covers the entire Baltic Sea. It is driven with atmospheric data dynamical downscaled from a GCM mimicking natural climate variability. The analysis focus on the role of variations in river discharge and precipitation, changes in wind speed and direction, fluctuations in temperature and shifts in large scale pressure patterns (e.g. NAO). Hereby, the length of the simulation will allow to identify mechanisms working on decadal to multi-decadal time scales. Moreover, it will be discussed how likely long stagnation periods are under natural climate variability and if the observed exceptional long stagnation period between 1983-1993 might be related to beginning climate change.

    Within the next few decades, wind farms with an extension of many square kilometres probably will be built in Swedish coastal waters. These installations may affect the ecological communities in various ways, e.g.; by the already known reef-effect, by changing the population structure of key predators such as fish and birds and thereby cause trophic cascades down into the benthic community or by causing changes in the hydrology that may benefit some species, mainly soft bottom species, while others may be disadvantaged. How the wind farms will affect the ecological communities depends probably very much on the initial conditions. During the period 2005-2009 a study was carried out with the aim to investigate the benthic community structure on hard bottoms, before and after larger wind farms have been constructed. The areas explored were Skottarevet in Kattegat, Lillgrund in Oeresund, Utgrunden II in southern Kalmar Strait, Kaarehamn off north-eastern Oeland and Klasaadern off south-western Gotland. For legal and economic reasons, only one farm, Lillgrund was constructed during the project period. Significant differences were found at both species and functional level. The largest divergence was found between the Kattegat and the Baltic Sea with large differences in species composition and in part also with other functional groups. Furthermore, between the Baltic Sea sites, significant differences were also found. The natural communities in the two straits had significantly higher biomass of blue mussels (M. edulis) per square meter compared with the open areas at Gotland and Oeland. In addition,the algal flora differed significantly. Filamentous brown algae favoured by eutrophication dominated the substrate in the straits while the bottoms along the open coastlines were covered with perennial red algae. The wind farm at Lillgrund affected the benthic communities moderately but significant. Mussels and barnacles colonized the surface of the towers and the granite

    The population structure of Atlantic herring (Clupea harengus) from 13 local, coastal and offshore areas of the North Sea, Skagerrak, Kattegat and western Baltic (northeast Atlantic) was studied using biological and environmental data from 1970–2015. The objective was to identify distinct populations by comparing variability in the temporal and spatial phenotypic characteristics and evaluate the potential for mixing of populations in time and space. The populations varied in biological characteristics such as mean vertebral counts (VS), growth and maturity ogives. Generalized additive models indicated temporally stable VS in the North Sea and western Baltic, whereas intra-annual temporal variation of VS occurred in other areas. High variability of VS within a population was not affected by environmental factors such as temperature and salinity. Consequently, seasonal VS variability can be explained by the presence or absence of herring populations as they migrate between areas. The three main populations identified in this paper correspond to the three managed stocks in this area: Norwegian spring spawners (NSS), western Baltic spring spawners (WBSS) and North Sea autumn spawners (NSAS). In addition, several local populations were identified in fjords or lakes along the coast, but our analyses could not detect direct mixing of local populations with the three main populations. Our results highlight the importance of recognizing herring dynamics and understanding the mixing of populations as a challenge for management of herring. PMID:29084258

  7. The Swedish wood fuel market

    1999-01-01

    In Sweden, wood fuels are traditionally used in the Swedish forest products industry and for heating of single-family houses. More recently they are also become established as an energy source for district heating and electricity production. Energy policy, especially the energy taxation system, has favoured wood fuels and other biofuels, mainly for environmental reasons. There is now an established commercial market for wood fuels in the district heating sector, which amounts to 45 PJ and is growing 20 per cent annually. Price levels have been stable in current prices for a decade, mainly because of good access to wood fuels. Price levels are dominated by production costs on a market that is largely governed by the buyer. It is expected that the use of wood fuels will increased in Sweden in the future, which will push a further development of this section on the market and bring about technological changes in the area.

    I very much enjoyed reading Jim Fleming’s article on Carl-Gustaf Rossby and the seminal contributions Rossby made to meteorology. Furthermore, the otherwise excellent article has two errors. Something must have gotten lost in translation to cause Fleming to claim that “Rossby pursued numerical weather prediction in Sweden in an era in which there was no Swedish word for digital computer.” With applied mathematician Germund Dahlquist, Rossby developed a weather model for the Binär Elektronisk Sekvens Kalkylator (BESK; Binary Electronic Sequence Calculator). Designed and built in Sweden, BESK was the world’s fastest computer when it became operational in 1953. From September 1954, BESK weather simulations enabled routine 24-hour national forecasts.

    the 1970s, energy production was politicized big time in the industrialized world. The birth of the environmental movement, the oil crises in 1973 - 74 and the beginning conflict surrounding civilian nuclear power, put energy issues center stage on the political agenda. Energy policies - especially related to the development of nuclear power - came to dominate election campaigns, like in Sweden in 1976 or be the subject of referendums, like in Austria in 1978 or in Sweden in 1980. Critical voices toward the peaceful use of nuclear power - having started in America before being exported to Europe - gained real strength and public support all over the Western world by the nuclear accident at the Three Mile Island plant in Harrisburg, Pennsylvania in 1979. The energy genie was out of the bottle and out to stay. Fueled by the nuclear meltdowns in Chernobyl in 1986 and in Fukushima in 2011 and supplemented by conflicts over how to reduce the use of oil and coal, how to sensibly exploit the waste gas reserves, and how to develop renewable energy sources based on sun, wind and waves – have made all kinds of energy issues the focal point of political contentions ever since the early 1970s. In Sweden, as in many other countries, energy policies - often with nuclear power in the center - have been one of the most fought-over policy areas during the last thirty-forty years. And the contentious character of energy policies is not limited to the elite level of politics - to politicians, to media pundits or to lobbyists. It is also manifest among ordinary citizens. Energy issues - nuclear power and wind power in particular - are highly polarizing among voters as well. Given this historic background, starting in the 1970s, it was rather natural that energy questions - featuring most prominently questions related to nuclear power - would be important parts of the voter surveys performed by the Swedish National Elections Studies (SNES) at the Univ. of Gothenburg.

    The effects of wind waves on the Baltic Sea water temperature has been studied by coupling the hydrodynamical model NEMO with the wave model WAM. The wave forcing terms that have been taken into consideration are: Stokes-Coriolis force, seastate dependent energy flux and sea-state dependent momentum flux. The combined role of these processes as well as their individual contributions on simulated temperature is analysed. The results indicate a pronounced effect of waves on surface temperature, on the distribution of vertical temperature and on upwellinǵs. In northern parts of the Baltic Sea a warming of the surface layer occurs in the wave included simulations. This in turn reduces the cold bias between simulated and measured data. The warming is primarily caused by sea-state dependent energy flux. Wave induced cooling is mostly observed in near coastal areas and is mainly due to Stokes-Coriolis forcing. The latter triggers effect of intensifying upwellings near the coasts, depending on the direction of the wind. The effect of sea-state dependent momentum flux is predominantly to warm the surface layer. During the summer the wave induced water temperature changes were up to 1 °C.

  11. Virulence Profiles of Vibrio vulnificus in German Coastal Waters, a Comparison of North Sea and Baltic Sea Isolates

    Directory of Open Access Journals (Sweden)

    Nadja Bier

    2015-12-01

    Full Text Available Vibrio vulnificus is a halophilic bacterium of coastal environments known for sporadically causing severe foodborne or wound infections. Global warming is expected to lead to a rising occurrence of V. vulnificus and an increasing incidence of human infections in Northern Europe. So far, infections in Germany were exclusively documented for the Baltic Sea coast, while no cases from the North Sea region have been reported. Regional variations in the prevalence of infections may be influenced by differences in the pathogenicity of V. vulnificus populations in both areas. This study aimed to compare the distribution of virulence-associated traits and genotypes among 101 V. vulnificus isolates from the Baltic Sea and North Sea in order to assess their pathogenicity potential. Furthermore, genetic relationships were examined by multilocus sequence typing (MLST. A high diversity of MLST sequences (74 sequence types and differences regarding the presence of six potential pathogenicity markers were observed in the V. vulnificus populations of both areas. Strains with genotypes and markers associated with pathogenicity are not restricted to a particular geographic region. This indicates that lack of reported cases in the North Sea region is not caused by the absence of potentially pathogenic strains.

  12. Effects of shore-level displacement on the ecology of Baltic Sea bays

    2012-12-15

    This report presents the up to date understanding of changes in ecological structure of small Baltic Sea bays following shore-level displacement and isolation of bays from the sea. It was produced as a part of the biosphere research programme, which has a strong emphasis on the characterization of properties and processes affecting the fate of potentially released radionuclides from the suggested repository of nuclear waste in the bedrock of the Forsmark area. The report has a focus on ecology and gives a description of input data, methodology and results on changes in flora and fauna communities, as well as some abiotic factors, with topographic isolation of bays from the sea. It is intended to describe the properties and conditions at the Forsmark site and to give information essential for demonstrating site specific understanding of processes and properties linked to a sea-to lake succession.

    This report presents the up to date understanding of changes in ecological structure of small Baltic Sea bays following shore-level displacement and isolation of bays from the sea. It was produced as a part of the biosphere research programme, which has a strong emphasis on the characterization of properties and processes affecting the fate of potentially released radionuclides from the suggested repository of nuclear waste in the bedrock of the Forsmark area. The report has a focus on ecology and gives a description of input data, methodology and results on changes in flora and fauna communities, as well as some abiotic factors, with topographic isolation of bays from the sea. It is intended to describe the properties and conditions at the Forsmark site and to give information essential for demonstrating site specific understanding of processes and properties linked to a sea-to lake succession.

  14. Biomass and Swedish energy policy

    International Nuclear Information System (INIS)

    Johansson, Bengt

    2001-01-01

    The use of biomass in Sweden has increased by 44% between 1990 and 1999. In 1999 it was 85 TWh, equivalent to 14% of the total Swedish energy supply. The existence of large forest industry and district heating systems has been an essential condition for this expansion. The tax reform in 1991 seems, however, to have been the most important factor responsible for the rapid bioenergy expansion. Through this reform, the taxation of fossil fuels in district heating systems increased by approximately 30-160%, depending on fuel, whereas bioenergy remained untaxed. Industry is exempted from the energy tax and pays reduced carbon tax. No tax is levied on fossil fuels used for electricity production. Investment grants have existed for biomass-based electricity production but these grants have not been large enough to make biomass-based electricity production economically competitive in a period of falling electricity prices. Despite this, the biomass-based electricity production has increased slightly between 1990 and 1999. A new taxation system aiming at a removal of the tax difference between the industry, district heating and electricity sectors has recently been analysed by the Swedish government. One risk with such a system is that it reduces the competitiveness for biomass in district heating systems as it seems unlikely that the taxes on fossil fuels in the industry and electricity sectors will increase to a level much higher than in other countries. A new system, based on green certificates, for supporting electricity from renewable energy sources has also been proposed by the government.

    EnBW Erneuerbare Energien GmbH, a wholly-owned subsidiary of EnBW AG, intends to operate two offshore wind farms in each of the Baltic and North Sea, respectively. The main distinguishing criterion for service concepts for operating offshore wind farms is the question of the service base location and of the maritime logistics. The paper provides an exemplary comparison between land- and sea-based service concepts, and assumes accessibility of the plant at specific offshore locations under various weather conditions. The paper not only presents the so far satisfactory production results of EnBW Baltic 1 but also informs about experience with weather conditions in the Baltic and about type and frequency of services provided there.

    Full Text Available In this article it is told about design and building in Russia of the first tower armored ships, are given their characteristics, are described design features, and also basic stages of service in the composition of Baltic fleet, the advantages and disadvantages in the projects are analyzed. The authors come to the conclusion that the first navigation of tower armored vehicles revealed many design flaws. Low-built monitors and two-turret armored boat had very poor seakeeping. However, for advertising purposes the ten monitors in 1865 have been sent to the coast of Sweden. During the operation it was determined the necessity of combining the reliable protection with sufficient seaworthiness. The solution to this problem is reflected in the subsequent types of armored ships – the tower frigates.

  19. Towards The Operational Oceanographic Model System In Estonian Coastal Sea, Baltic Sea

    Kõuts, T.; Elken, J.; Raudsepp, U.

    An integrated system of nested 2D and 3D hydrodynamic models together with real time forcing data asquisition is designed and set up in pre-operational mode in the Gulf of Finland and Gulf of Riga, the Baltic Sea. Along the Estonian coast, implicit time-stepping 3D models are used in the deep bays and 2D models in the shallow bays with ca 200 m horizontal grid step. Specific model setups have been verified by in situ current measurements. Optimum configuration of initial parameters has been found for certain critical locations, usually ports, oil terminals, etc. Operational system in- tegrates also section of historical database of most important hydrologic parameters in the region, allowing use of certain statistical analysis and proper setup of initial conditions for oceanographic models. There is large variety of applications for such model system, ranging from environmental impact assessment at local coastal sea pol- lution problems to forecast of offshore blue algal blooms. Most probable risk factor in the coastal sea engineering is oil pollution, therefore current operational model sys- tem has direct custom oriented output the oil spill forecast for critical locations. Oil spill module of the operational system consist the automatic weather and hydromet- ric station (distributed in real time to internet) and prognostic model of sea surface currents. System is run using last 48 hour wind data and wind forecast and estimates probable oil deposition areas on the shoreline under certain weather conditions. Cal- culated evolution of oil pollution has been compared with some real accidents in the past and there was found good agreement between model and measurements. Graphi- cal user interface of oil spill model is currently installed at location of port authorities (eg. Muuga port), so in case of accidents it could be used in real time supporting the rescue operations. In 2000 current pre-operational oceanographic model system has been sucessfully used to

  1. The Influence of Weather Anomalies on Mercury Cycling in the Marine Coastal Zone of the Southern Baltic-Future Perspective.

    Bełdowska, Magdalena

    2015-01-01

    Despite the decreased emission loads of mercury, historical deposits of this metal in various compartments of the environment may become an additional diffuse source in the future. Global climate change manifests itself in the temperate zone in several ways: warmer winters, shorter icing periods, increased precipitation and heightened frequency of extreme events such as strong gales and floods, all of which cause disturbances in the rate and direction of mercury biogeochemical cycling. The present study was conducted at two sites, Oslonino and Gdynia Orlowo (both in the coastal zone of the Gulf of Gdansk), from which samples were collected once a month between January 2012 and December 2012. In the Southern Baltic region, climate changes can certainly enhance coast to basin fluxes of mercury and the transfer of bioavailable forms of this metal to the food web. They may also, in the future, contribute to uncontrollable increases of mercury in the seawater.

    The potential capability to decompose macromolecular compounds, and the level of extracellular enzyme activities were determined in heterotrophic bacteria isolated from a sandy beach in Sopot on the Southern Baltic Sea coast. Individual isolates were capable of hydrolysing a wide spectrum of organic macromolecular compounds. Lipids, gelatine, and DNA were hydrolyzed most efficiently. Only a very small percentage of strains were able to decompose cellulose, and no pectinolytic bacteria were found. Except for starch-hydrolysis, no significant differences in the intensity of organic compound decomposition were recorded between horizontal and vertical profiles of the studied beach. Of all the studied extracellular enzymes, alkaline phosphatase, esterase lipase, and leucine acrylaminidase were most active; in contrast, the activity α-fucosidase, α-galactosidase and β-glucouronidase was the weakest. The level of extracellular enzyme activity was similar in both sand layers.

    The investigation of climatic processes and behaviour examines the effects of climatic changes on human beings and the surrounding environment. The authors discuss, in a wide-subject perspective, the regional impacts of the greenhouse effect, increase of the sea level, and changed conditions of both precipitation and wind using the North and Baltic Sea as examples. In this effort, questions dealing with changes of water level, motion and (disturbance) of the sea and morphodynamic in the coastal apron, in reference to requirements on a future protection of the shore, are handled. In addition, not only the aspects of ecosystem-orientated adaption in the strip of land between the continent northern islands 'Wattenmeer' and ground landscape (Bodenlandschaft) are taken into consideration, but also the impact of these on human beings and their interest to use the coastal regions.

  10. Natural gas co-operation in the Baltic region

    International Nuclear Information System (INIS)

    Jensen, J.K.

    1996-01-01

    Co-operation between the gas companies in the Baltic Region has been in place for several years. The overview given in this paper shows that the co-operation has been developed in trade, investments, privatisation and participation in the restructuring process. Finally, through a broad technical co-operation, significant efforts are made to establish common operational practices, codes and standards and the integrity of gas transmission pipelines. The Baltic Region, from a resource and gas interconnection point of view, enjoys a strategic position in the future development of the gas industry in Europe. The Baltic gas sector represents an interesting and growing gas market with the significant gas storage capacity. The region is also located strategically for planned gas interconnections and could serve as a transit corridor for the future gas supplies from western Siberia or the North Sea. This co-operation in the region is being supported by international regulations and agreements such as the Energy Charter between the European Union and the central and east European countries. However, at present the gas industry in the Baltic Region seems to be ahead of these international agreements. It may well be seen that trade arrangements such as Third Party Access are implemented directly by market forces rather than through international agreements. The regional development may thus be a driving force for the implementation of the Internal Energy Market for the gas industry

  18. The independent Baltic states: Maritime law and resource management implications

    International Nuclear Information System (INIS)

    Canfield, J.L.

    1993-01-01

    The achievement of independence by the Baltic states impacts nearly all aspects of the maritime law and resource management regimes appertaining to the Baltic Sea. The unique position of these states, given their maritime history and role as a bridge between East and West, warrants reconsideration. The Baltic Sea basin is among the most highly industrialized shorelines in the world, accounting for approximately 15% of world industrial output, and is relatively dense in population. Large quantities of pollutants water its waters by way of industrial, agricultural, and municipal waste. A lack of adequate sewage treatment accounts for much of the waste. The Baltic is also especially sensitive to oil pollution as the relatively cold water inhibits bacteriological breakdown. Important issues of maritime border delimitation, treaty devolution, and the potential for reinstitution of exclusionary regimes reappeared with the attainment of independence. Further, the legacy of Soviet maritime environment and resource management has engendered fundamental political, social, and economic conflicts for which resources and effective management structures are lacking. The competing requirements of economic development, reintegration into Western markets, and management of critical marine resources highlights the need for comprehensive and regionally focused approaches to the problems identified

    1992-01-01

    The Swedish Final Repository for Radioactive Waste (SFR) has been in operation since 1988 and is located in the crystalline rock, 60 m below the Baltic Sea. In the licensing procedure for the SFR the safety assessment has been complemented with a detailed scenario analysis of the performance of the repository. The scenarios include the influence on radionuclide release by gas formation and gas transport processes in the silo. The overall conclusion is that the release of most radionuclides from the silo is only marginally affected by the formation and release of gas, even for scenarios considering unexpected events. The largest effects were found for short-lived radionuclides and radionuclides that have no or low sorption ability. Except for very extreme scenarios for the silo the overall impact from repository on the environment is by far dominated by the release of radionuclides from the rock vaults. 10 refs., 6 figs

  7. Impact of marine mercury cycling on coastal atmospheric mercury concentrations in the North- and Baltic Sea region

    Full Text Available Abstract The cycling of mercury between ocean and atmosphere is an important part of the global Hg cycle. Here we study the regional contribution of the air-sea exchange in the North- and Baltic Sea region. We use a newly developed coupled regional chemistry transport modeling (CTM system to determine the flux between atmosphere and ocean based on the meteorological model COSMO-CLM, the ocean-ecosystem model ECOSMO, the atmospheric CTM CMAQ and a newly developed module for mercury partitioning and speciation in the ocean (MECOSMO. The model was evaluated using atmospheric observations of gaseous elemental mercury (GEM, surface concentrations of dissolved gaseous mercury (DGM, and air-sea flux (ASF calculations based on observations made on seven cruises in the western and central Baltic Sea and three cruises in the North Sea performed between 1991 and 2006. It was shown that the model is in good agreement with observations: DGM (Normalized Mean Bias NMB=-0.27 N=413, ASF (NMB=-0.32, N=413, GEM (NMB=0.07, N=2359. Generally, the model was able to reproduce the seasonal DGM cycle with the best agreement during winter and autumn (NMBWinter=-0.26, NMBSpring=-0.41, NMBSummer=-0.29, NMBAutumn=-0.03. The modelled mercury evasion from the Baltic Sea ranged from 3400 to 4000 kg/a for the simulation period 1994–2007 which is on the lower end of previous estimates. Modelled atmospheric deposition, river inflow and air-sea exchange lead to an annual net Hg accumulation in the Baltic Sea of 500 to 1000 kg/a. For the North Sea the model calculates an annual mercury flux into the atmosphere between 5700 and 6000 kg/a. The mercury flux from the ocean influenced coastal atmospheric mercury concentrations. Running CMAQ coupled with the ocean model lead to better agreement with GEM observations. Directly at the coast GEM concentrations could be increased by up to 10% on annual average and observed peaks could be reproduced much better. At stations 100km downwind

    Acidity and leaching of metals from acid sulphate soils (ASSs) impair the water quality of receiving surface waters. The largest ASS areas in Europe are found in the coasts of the northern Baltic Sea. We used weight-of-evidence (WoE) approach to assess potential risks in 14 estuary sites affected by ASS in the Gulf of Finland, northern Baltic Sea. The assessment was based on exposure and effect profiles utilizing sediment and water metal concentrations and concurrent pH variation, sediment toxicity tests using the luminescent bacterium Vibrio fischeri and the midge Chironomus riparius, and the ecological status of benthic macroinvertebrate communities. Sediment metal concentrations were compared to national sediment quality criteria/guidelines, and water metal concentrations to environmental quality standards (EQSs). Hazard quotients (HQs) were established for maximum aluminium, cadmium and zinc concentrations at low pH based on applicable US EPA toxicity database. Sediment metal concentrations were clearly elevated in most of the studied estuaries. The EQS of cadmium (0.1 μg/l) was exceeded in 3 estuaries out of 14. The pH-minima were below the national threshold value (5.5) between good and satisfactory water quality in 10 estuaries. V. fischeri bioluminescence indicated toxicity of the sediments but toxic response was not observed in the C. riparius emergence test. Benthic invertebrate communities were deteriorated in 6 out of 14 sites based on the benthic invertebrate quality index. The overall ecotoxicological risk was assessed as low in five, moderate in three and high in five of the estuary sites. The risk assessment utilizing the WoE approach indicated that harmful effects of ASSs are likely to occur in the Baltic Sea river estuaries located at the ASS hotspot area. - Highlights: • Acid sulphate soils release high amounts of metals and acidity. • Metals and acidity are transported to estuary sites. • Acid sulphate soils impair the ecological status

    The Integrated Ocean Drilling Program (IODP) expedition 347 cored sediments from different settings of the Baltic Sea covering the last glacial-interglacial cycle. The main aim was to study the geological development of the Baltic Sea in relation to the extreme climate variability of the region with changing ice cover and major shifts in temperature, salinity, and biological communities. Using the Greatship Manisha as a European Consortium for Ocean Research Drilling (ECORD) mission-specific platform, we recovered 1.6 km of core from nine sites of which four were additionally cored for microbiology. The sites covered the gateway to the North Sea and Atlantic Ocean, several sub-basins in the southern Baltic Sea, a deep basin in the central Baltic Sea, and a river estuary in the north. The waxing and waning of the Scandinavian ice sheet has profoundly affected the Baltic Sea sediments. During the Weichselian, progressing glaciers reshaped the submarine landscape and displaced sedimentary deposits from earlier Quaternary time. As the glaciers retreated they left a complex pattern of till, sand, and lacustrine clay, which in the basins has since been covered by a thick deposit of Holocene, organic-rich clay. Due to the stratified water column of the brackish Baltic Sea and the recurrent and widespread anoxia, the deeper basins harbor laminated sediments that provide a unique opportunity for high-resolution chronological studies. The Baltic Sea is a eutrophic intra-continental sea that is strongly impacted by terrestrial runoff and nutrient fluxes. The Holocene deposits are recorded today to be up to 50 m deep and geochemically affected by diagenetic alterations driven by organic matter degradation. Many of the cored sequences were highly supersaturated with respect to methane, which caused strong degassing upon core recovery. The depth distributions of conservative sea water ions still reflected the transition at the end of the last glaciation from fresh-water clays to

    Flatfish in the northern Baltic Sea are facing multiple environmental pressures due to on-going large-scale ecosystem changes linked to eutrophication and climate change. Shallow juvenile habitats of flatfishes are expected to be especially susceptible to these environmental pressures. Using previously unpublished historical and present-state data on juvenile flatfish in nursery areas along the Finnish coast we demonstrate a drastic (up to 40 ×) decline in 1-Y-O flounder densities since the 1980s and a particularly low current occurrence of both flounders and turbots in several known juvenile habitats. As a consequence of ongoing coastal eutrophication vegetation coverage and filamentous algae have generally increased in shallow areas. We examined the predicted negative effect of vegetation/algae by exploring quantitative relationships between juvenile flatfish (flounder and turbot) occurrence and vegetation/algae among other environmental factors in shallow juvenile habitats. Despite sparse occurrence of juveniles we found a significant negative relationship between flatfish abundance and vegetation cover, implicating eutrophication as a potential major driver affecting the value of juvenile habitat. Shallow littoral habitats play a particularly central role for flatfish due to the spatial concentration of fish in these areas during the critical juvenile stage. Despite their importance, these areas have been relatively poorly studied in the northern Baltic Sea, which makes it difficult to quantify overall changes in environmental conditions and to relate these changes to flatfish recruitment. The low present-state flatfish densities recorded preclude strong inferences of the role of habitat quality to be drawn. Our study does, however, provide a baseline for future assessment. Based on existing evidence, we cannot thus establish any bottlenecks but hypothesize that the current low occurrence of juvenile flatfish, and the population decline of flounder on the

  11. Baltic States in NATO: Results of the Decade

    Full Text Available In the post-Soviet period participation in NATO was one of the major goals of euro-atlantic integration for the Baltic states. Political leaders of Estonia, Latvia and Lithuania have considered participation in the alliance as an important element of euro-atlantic solidarity which allows small - from all viewpoints - states claim decision-making over global issues. This satisfies demands of the political elites and victimized public consciousness for more security, makes it possible for elites to consider their states as bulwark against Russia. Throughout the whole decade, such reasoning has been reflected in doctrines and speeches of Baltic politicians. After joining NATO, the Baltic states became the most active supporters of a deeper integration in the military area and "open door" policy. They have continued reforming their armed forces and renovating military infrastructure. They have acquired "specialization" within NATO by establishing centers of excellence. In terms of euro-atlantic solidarity, the participation in the International Security Assistance Force in Afganistan has become the most important international project for the Baltic states. However, only Estonia managed to mount their defence expenses to the level of 2% GDP. During the „Ukranian crisis" the issue of Baltic membership in NATO acquired special importance. Confrontational rhetoric and appeals to "Russian threat" in Estonia, Latvia and Lithuania, on the one hand, make it possible for their political leaders to constantly demonstrate their importance in the eyes of Western partners and demand more activity of the alliance and, on the other hand, make ground for the political elites to consolidate the electorate, by that ensuring that the right-wing conservative forces remain in power.

    In this desk study, the available geophysical and geological data on the crustal structure and regional tectonics of the wider surroundings of the Aespoe site (SE Sweden and adjacent parts of the Baltic Sea) are compiled and assessed. The aim is to contribute to the knowledge base for long-term rock mechanical modeling, using the Aespoe site as a proxy for a high-level radioactive waste repository site in Swedish bedrock. The geophysical data reviewed includes two new refraction/wide-angle reflection seismic experiments carried out within the EUROBRIDGE project, in addition to the numerous earlier refraction seismic profiles. The BABEL normal-incidence deep seismic profile is also considered. New geological data, presented at EUROBRIDGE workshops, and in recent SGU publications, are reviewed for the same area. In combination with the seismic data, these provide a base for interpreting the present composition and structure, and the Palaeoproterozoic-Mesoproterozoic evolution, of the crustal segment within which the Aespoe site lies - the Smaaland mega-block. This is characterized by having undergone little regionally significant deformation or magmatism since Neoproterozoic times (the last 1000 million years). It is shown that, at this scale of observation (of the order of 100 km), the long-term rheology of the lithosphere can be argued from a relatively tight observational network, when combined with the results of earlier SKB studies (seismo-tectonics, uplift patterns, state of stress, heat flow) and published research. Although many uncertainties exist, the present state of knowledge would suffice for first exploratory calculations and sensitivity studies of long-term, large-scale rock mechanics

    Full Text Available In this study, retrievals of the medium resolution imaging spectrometer (MERIS reflectances and water quality products using four different coastal processing algorithms freely available are assessed by comparison against sea-truthing data. The study is based on a pair-wise comparison using processor-dependent quality flags for the retrieval of valid common macro-pixels. This assessment is required in order to ensure the reliability of monitoring systems based on MERIS data, such as the Swedish coastal and lake monitoring system (http://vattenkvalitet.se. The results show that the pre-processing with the Improved Contrast between Ocean and Land (ICOL processor, correcting for adjacency effects, improves the retrieval of spectral reflectance for all processors. Therefore, it is recommended that the ICOL processor should be applied when Baltic coastal waters are investigated. Chlorophyll was retrieved best using the FUB (Free University of Berlin processing algorithm, although overestimations in the range 18–26.5%, dependent on the compared pairs, were obtained. At low chlorophyll concentrations (−3, data dispersion dominated in the retrievals with the MEGS (MERIS ground segment processor processor. The lowest bias and data dispersion were obtained with MEGS for suspended particulate matter, for which overestimations in the range of 8–16% were found. Only the FUB retrieved CDOM (coloured dissolved organic matter correlate with in situ values. However, a large systematic underestimation appears in the estimates that nevertheless may be corrected for by using a local correction factor. The MEGS has the potential to be used as an operational processing algorithm for the Himmerfjärden bay and adjacent areas, but it requires further improvement of the atmospheric correction for the blue bands and better definition at relatively low chlorophyll concentrations in the presence of high CDOM attenuation.

  16. Estimating Swedish biomass energy supply

    International Nuclear Information System (INIS)

    Johansson, J.; Lundqvist, U.

    1999-01-01

    Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy

    Since the mid-1970s, the Swedish Nuclear Fuel and Waste Management Company (SKB) has been carrying out geoscientific research and feasibility studies aimed at identifying suitable sites for deep repositories in the Precambrian basement of the Baltic Shield. The documentation of this research effort forms an extensive body of material which is exceptionally wide-ranging and which is generally little known outside the Swedish nuclear waste community. This has now been compiled in the form of a 'documentation guide' in order to make the research results more easily accessible to the scientific community at large, and to show how they relate to their 'nearest surroundings', i.e. the relevant academic scientific literature and the documentation of similar research by other institutions, in Sweden and in other countries (Finland, Canada). The documentation covers the period 1976-2000 and contains ca. 850 citations, of which about half are technical reports published by SKB and its forerunners. In the main body of the guide (Chapters 2-9), the material is arranged thematically and the scope of the documentation in each theme is described and commented in short texts, showing the interrelationships between the individual reports and scientific papers, with appropriate cross-references. Early chapters (2-5, and 7) cover general themes: bedrock geology, fracturing, glaciation and crustal dynamics, deep groundwater, and geosphere transport, each subdivided into citation groups under headings which are of particular interest to the Swedish deep repository siting programme. Later chapters (6, and 8-9) include thumbnail sketches of the Swedish study sites (Finnsjoen, Fjaellveden, Gideaa, Kamlunge, Klipperaas, Sternoe), the underground laboratory sites of Stripa and Aespoe, and comparable sites in Finland and Canada, as well as the complete documentation to the feasibility studies carried out in eight Swedish municipalities between 1993 and 2000 (Storuman

  19. The Carbon Dioxide System in the Baltic Sea Surface Waters

    Energy Technology Data Exchange (ETDEWEB)

    Wesslander, Karin

    2011-05-15

    The concentration of carbon dioxide (CO{sub 2}) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the CO{sub 2} system have to be investigated. One piece is how the coastal seas, which are used by people and influenced by industrialization, are functioning. In this thesis, the CO{sub 2} system in the Baltic Sea surface water has been investigated using observations from the last century to the present. The Baltic Sea is characterized of a restricted water exchange with the open ocean and a large inflow of river water. The CO{sub 2} system, including parameters such as pH and partial pressure of CO{sub 2} (pCO{sub 2}), has large seasonal and inter-annual variability in the Baltic Sea. These parameters are affected by several processes, such as air-sea gas exchange, physical mixing, and biological processes. Inorganic carbon is assimilated in the primary production and pCO{sub 2} declines to approx150 muatm in summer. In winter, pCO{sub 2} levels increase because of prevailing mineralization and mixing processes. The wind-mixed surface layer deepens to the halocline (approx60 m) and brings CO{sub 2}- enriched water to the surface. Winter pCO{sub 2} may be as high as 600 muatm in the surface water. The CO{sub 2} system is also exposed to short-term variations caused by the daily biological cycle and physical events such as upwelling. A cruise was made in the central Baltic Sea to make synoptic measurements of oceanographic, chemical, and meteorological parameters with high temporal resolution. Large short-term variations were found in pCO{sub 2} and oxygen (O{sub 2}), which were highly correlated. The diurnal variation of pCO{sub 2} was up to 40 muatm. The CO{sub 2} system in the Baltic Sea changed as the industrialization increased around 1950, which was demonstrated using a coupled physical-biogeochemical model of the CO{sub 2} system

    The Bonneville Power Administration is proposing to build a transmission line to reinforce electrical service to the southern coast of Oregon. This FYI outlines the proposal, tells how one can learn more, and how one can share ideas and opinions. The project will reinforce Oregon`s south coast area and provide the necessary transmission for Nucor Corporation to build a new steel mill in the Coos Bay/North Bend area. The proposed plant, which would use mostly recycled scrap metal, would produce rolled steel products. The plant would require a large amount of electrical power to run the furnace used in its steel-making process. In addition to the potential steel mill, electrical loads in the south Oregon coast area are expected to continue to grow.

    Otoliths of perch (Perca fluviatilis), pike (Esox lucius) and European whitefish (Coregonus lavaretus) caught at different locations in the northern Baltic Sea along the Finnish west coast and at some rivers and lakes were subjected to elemental analyses with particle induced X-ray emission and laser ablation inductively coupled plasma mass spectrometry. The strontium concentration in otoliths from whitefish (∼3300 μg/g) was 2–3 times higher than that of perch and pike (∼1400 μg/g), while within species the strontium concentration of otoliths from fish caught at different locations was in the same range. The strontium concentrations were lowest in fish from the lakes (∼450 μg/g). Whitefish otoliths contained more zinc (∼60 μg/g) than those of pike (∼30 μg/g), while the zinc concentration in perch otoliths were below the detection limit. No spatial intraspecies variations in zinc concentrations were observed. X-ray diffraction showed that the otoliths consisted of aragonite solely

    2010-01-01

    The Neva Estuary situated in the eastern Gulf of Finland is one of the largest estuaries of the Baltic Sea with a large conurbation, St. Petersburg, situated on its coast. Eutrophication, alien species and large-scale digging and dumping of bottom sediment are the most prominent anthropogenic impacts on its ecosystem. However, many ecosystem responses, which are traditionally attribute to these impacts, are related to natural dynamics of the ecosystem. Fluctuations in discharge of the Neva River, intrusions of bottom hypoxic waters from the western part of the Gulf of Finland, higher summer temperatures and a shorter period of ice cover are climatic mediated factors inducing adverse changes in its ecosystem from the 1980s onwards. The main ecosystem responses to these factors are 2-3-fold increase of trophic status, deterioration of native zoobenthic communities and establishment of alien species, as well as the many fold decrease of fish catch and the population of ringed seal in the region.

  5. Safety Assessment - Swedish Nuclear Power Plants

    1996-12-31

    After the reactor accident at Three Mile Island, the Swedish nuclear power plants were equipped with filtered venting of the containment. Several types of accidents can be identified where the filtered venting has no effect on the radioactive release. The probability for such accidents is hopefully very small. It is not possible however to estimate the probability accurately. Experiences gained in the last years, which have been documented in official reports from the Nuclear Power Inspectorate indicate that the probability for core melt accidents in Swedish reactors can be significantly larger than estimated earlier. A probability up to one in a thousand operating years can not be excluded. There are so far no indications that aging of the plants has contributed to an increased accident risk. Maintaining the safety level with aging nuclear power plants can however be expected to be increasingly difficult. It is concluded that the 12 Swedish plants remain a major threat for severe radioactive pollution of the Swedish environment despite measures taken since 1980 to improve their safety. Closing of the nuclear power plants is the only possibility to eliminate this threat. It is recommended that until this is done, quantitative safety goals, same for all Swedish plants, shall be defined and strictly enforced. It is also recommended that utilities distributing misleading information about nuclear power risks shall have their operating license withdrawn. 37 refs.

    In 2007 HELCOM launched a plan for transboundary management of the Baltic Sea. This plan, called the Baltic Sea Action Plan (BSAP), aims amongst other things, to reduce eutrophication in the different regions of the Baltic Sea by reducing incoming nutrient loads from all discharging drainage basins...... difficult to achieve, and that additional abatement measures are likely to be required to fulfil these targets. The minimised total cost of delivering the achievable load reductions across the 9 Baltic littoral countries is estimated to be 4.69 billion Euros, annually, with substantial differences...

    The diet of whiting Merlangius merlangus in the western Baltic Sea was investigated and compared to the diet in the southern North Sea. Clupeids were important prey in both areas, but especially in the western Baltic Sea where they constituted up to 90% of the diet of larger individuals. Gobies......, brown shrimps and polychaetes were the main prey of juveniles in the western Baltic Sea, while a wider range of species were consumed in the North Sea. The shift to piscivory occurred at smaller sizes in the western Baltic Sea and the fish prey consumed was proportionately larger than in the southern...

    Full Text Available The efficiency of banks has been widely and extensively studied in the past few decades. Using a sample of Balkan and Baltic countries and by employing a Data Envelopment Analysis model, we want to highlight the main challenges for the highly concentrated banking system. Over the period 2007 - 2011, these countries have coped with the worst financial crisis from the Great Depression, which has severe effects on the banking systems. Our sample includes the least developed countries in the EU and for reference purpose, Luxembourg, with the highest GDP per capita. We expect to find similarities between Balkan countries and Baltic countries and we can draw lessons from Luxembourg`s results.

    2011-01-01

    in the central Baltic Sea, namely the Bornholm Basin, Gdansk Deep and Southern Gotland Basin. Environmental parameters such as hydrography, fish condition and stock density were tested in order to investigate the observed variability in sprat fecundity. Absolute batch fecundity was found to be positively related...... to fish length and weight. Significant differences in absolute and relative batch fecundity of Baltic sprat among areas and years were detected, and could partly be explained by hydrographic features of the investigated areas. A non-linear multiple regression model taking into account fish length...... and ambient temperature explained 70% of variability in absolute batch fecundity. Oxygen content and fish condition were not related to sprat batch fecundity. Additionally, a negative effect of stock size on sprat batch fecundity in the Bornholm Basin was revealed. The obtained data and results are important...

  13. Transitivity pairs in Baltic: between Finnic and Slavic

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available In this paper we examine transitivity pairs in the two modern Baltic languages Lithuanian and Latvian and compare them to neighbouring Finnic (Finnish, Estonian and Slavic (Russian, Polish languages. In Slavic the main strategy is to derive the intransitive (noncausal verb from the transitive (causal verb, while in Finnic we find a high number of derived causatives. Baltic uses both techniques, and in addition, there is a higher number of pairs where either both verbs are marked, or two etymologically related verbs are underived from a synchronic point of view. Differences and similarities across the six languages are investigated, using a list of 20 notions divided into five groups. Special attention is paid to animacy and to the distinction between inchoative and durative noncausal verbs.

  14. On the Baltic Sea Response to Climate Change: Model Implications

    International Nuclear Information System (INIS)

    Omstedt, Anders; Leppaeranta, Matti

    1999-01-01

    The sensitivity of the Baltic Sea to climate change is reviewed on the basis of recent model studies. In general, the presently available models indicate that the Baltic Sea is a most sensitive system to climate change, particularly in air temperature, wind, fresh water inflow and the barotropic forcing in the entrance area. Available scenarios for ice conditions and climate warming around year 2100 show 2-3 months' shortening of the ice season in the Bothnian Bay and about 0.4 m decrease in the maximum annual ice thickness. Corresponding scenarios for climate cooling show 1-2 months' longer ice season in the Bothnian Bay and 0.2 - 0.5 m increase in the maximum annual ice thickness

  15. Tectonic lineaments in the Baltic from Gaevle to Simrishamn

    1977-12-01

    The present report deals with the tectonic pattern within the offshore area of middle and SE Sweden. The study is restricted to the large scale pattern that can be detected by seismic reflection profiling. Neotectonic events are discussed in connection with the special study of echosounding and seismic records from the Baltic Sea. This report is mainly based on investigations performed during the period 1966-1976 by means of continuous seismic reflection profiling. The investigations were mainly concentrated to areas with a sedimentary rock cover and thus, there is a large discrepance in the amount of available information between different parts of the Baltic. In the coastal zone, only those tectonic lineaments that are of importance for the understanding of the offshore conditions are included in the present maps. References to other known lineaments are made in the text

    2018-05-01

    Natural Baltic amber (succinite) is the most appreciated fossil resin of the rich cultural traditions dating back to prehistoric times. Its unequivocal identification is extremely important in many branches of science and trades including archeology, paleontology, chemistry and finally mineralogical and gemological societies. Current methods of modification of natural succinite are more and more sophisticated making the identification of natural Baltic amber often challenging. In article the systematic analytical approach for identification of natural and modified under different conditions succinite, using mid-infrared spectroscopy (transmission, Drifts and ATR techniques) is presented. The correlation between spectral characteristics and properties of succinite is discussed pointing that the understanding of the nature of changes is the key of identification of this precious material.

    during the egg phase to be of critical importance. Two years of extensive field investigations in the Bornholm Basin, central Baltic Sea, were undertaken. In 2002, a typical stagnation situation characterized by low salinity and poor oxygen conditions was investigated, and in early 2003, a major inflow...... of North Sea water completely changed the hydrographic conditions by increasing salinity and oxygen content, thereby altering ecological conditions. The goal was to quantify egg mortality caused by predation and hydrography, and to compare these estimates with independent estimates based on cohort analysis....... Results indicated high intra-annual variability in egg mortality. Cod and sprat egg mortality responded differently to the major Baltic inflow: mortality related to hydrographic conditions increased for sprat and decreased for cod. On the other hand, predation mortality during peak spawning decreased...

  18. Labor Share in National Income: Implications in the Baltic Countries

    2017-06-01

    Full Text Available Despite the fact that stability of labor share in national income is a key foundation in macroeconomic models, scientists acknowledge, that in the last three decades it has been declining around the world. The Baltic countries are not an exception; they follow similar patters to large economies, thus the research aims at determining economic factors at play. With the help of error correction model and time series data covering the past twenty years, we determine factors which contribute to the decline of labor share in the Baltic countries. We find significant long-term relationships between labor share and government spending, trade openness, and emigration. Government spending exhibits the highest contribution to variance of labor share in Lithuania, which also explains a large part of Latvia’s labor share variations. We find many similarities between the analyzed countries, however some differences are also visible.

    It has been shown that 210 Po and plutonium are significantly more concentrated in the Baltic Sea ecosystem than uranium . Bioaccumulation coefficients in flora and fauna (BCFs) of 210 Po are of the 2·10 3 - 2·10 5 range and plutonium - of the 1·10 2 - 1·10 4 . 238 Pu/ 239-240 Pu isotopic ratio shows for the increasing content in the living organisms of plutonium coming from the Chernobyl NPP accident. Content of 55 Fe and 63 Ni in the Baltic ecosystem (sea water, Fucus Vesilculous) is inverse proportional to the distance from the contamination place (e.g. from the NPP). Against to 55 Fe - 63 Ni is accumulated in the fish skin and flakes through passive diffusion

    Baltic amber constitutes the largest known deposit of fossil plant resin and the richest repository of fossil insects of any age. Despite a remarkable legacy of archaeological, geochemical and palaeobiological investigation, the botanical origin of this exceptional resource remains controversial. Here, we use taxonomically explicit applications of solid-state Fourier-transform infrared (FTIR) microspectroscopy, coupled with multivariate clustering and palaeobotanical observations, to propose that conifers of the family Sciadopityaceae, closely allied to the sole extant representative, Sciadopitys verticillata, were involved in the genesis of Baltic amber. The fidelity of FTIR-based chemotaxonomic inferences is upheld by modern-fossil comparisons of resins from additional conifer families and genera (Cupressaceae: Metasequoia; Pinaceae: Pinus and Pseudolarix). Our conclusions challenge hypotheses advocating members of either of the families Araucariaceae or Pinaceae as the primary amber-producing trees and correlate favourably with the progressive demise of subtropical forest biomes from northern Europe as palaeotemperatures cooled following the Eocene climate optimum.

  1. Shaping Baltic States Defence Strategy: Host Nation Support

    Directory of Open Access Journals (Sweden)

    Otzulis Valdis

    2017-12-01

    Full Text Available The presence of NATO troops in the Baltic states has increased in the last years due to changing international environment, increased level of potential risks and threats, and necessity to enhance deterrence in the region. As a result of NATO’s Wales and Warsaw summits decisions, Estonia, Latvia, and Lithuania are entitled to host a battalion size battle group. The article aims at investigating how host nation support (HNS can contribute to the national defence and, additionally, to the self-defence capabilities of the Baltic states. The concept of HNS is present in the national defence concepts of all three countries. However, its active application and utilization started in the last two years. The article argues that more intensive incorporation of an HNS system in national defence policies serve the capability development in fields like national military logistics, infrastructure, and civil-military cooperation. Those capabilities can serve as an extension of the national defence.

    2011-01-01

    Full Text Available The first fossil cyphophthalmid harvestman (Opiliones: Cyphophthalmi from Palaeogene (Eocene Baltic amber is described. This is only the third fossil example of this basal harvestman lineage; the others being from the probably slightly younger Bitterfeld amber and the much older, early Cretaceous, Myanmar (Burmese amber. Although incomplete and lacking most of the appendages, the new Baltic amber fossil can be identified as a female. The somatic characters preserved, especially spiracle morphology and the coxo-genital region, allow it to be assigned with some confidence to the extant genus Siro Latreille, 1796 (Sironidae. This fossil is formally described here as Siro balticus sp. nov. It resembles modern North American Siro species more than modern European ones, and can be distinguished principally on its relatively large size and the outline form of the body.

    While the series of events that shaped the transition between foraging societies and food producers are well described for Central and Southern Europe, genetic evidence from Northern Europe surrounding the Baltic Sea is still sparse. Here, we report genome-wide DNA data from 38 ancient North Europeans ranging from ~9500 to 2200 years before present. Our analysis provides genetic evidence that hunter-gatherers settled Scandinavia via two routes. We reveal that the first Scandinavian farmers derive their ancestry from Anatolia 1000 years earlier than previously demonstrated. The range of Mesolithic Western hunter-gatherers extended to the east of the Baltic Sea, where these populations persisted without gene-flow from Central European farmers during the Early and Middle Neolithic. The arrival of steppe pastoralists in the Late Neolithic introduced a major shift in economy and mediated the spread of a new ancestry associated with the Corded Ware Complex in Northern Europe.

    2017-03-01

    Full Text Available The article presents the preliminary results of a research aimed at preparation for the extraction of chemical ammunition immersed after the Second World War(WWII in the waters of the Baltic Sea (BS. It has been 70 years since the first steps aiming at elimination of mainly German chemical weapons were taken, while the expected durability (tightness of metal barrels construction or other containers was estimated at 50-60 years. Consequently there is a serious risk of contamination of the Baltic Sea waters, not only with toxic warfare agents but also with the products of their decomposition. The evaluation of barrels’ and containers’ with TWA corrosion processes progress will determine the possibility of these munitions extraction to the surface in order to perform their classic utilization.

  5. Baltic Sea biodiversity status vs. cumulative human pressures

    2015-01-01

    Abstract Many studies have tried to explain spatial and temporal variations in biodiversity status of marine areas from a single-issue perspective, such as fishing pressure or coastal pollution, yet most continental seas experience a wide range of human pressures. Cumulative impact assessments have...... been developed to capture the consequences of multiple stressors for biodiversity, but the ability of these assessments to accurately predict biodiversity status has never been tested or ground-truthed. This relationship has similarly been assumed for the Baltic Sea, especially in areas with impaired...... status, but has also never been documented. Here we provide a first tentative indication that cumulative human impacts relate to ecosystem condition, i.e. biodiversity status, in the Baltic Sea. Thus, cumulative impact assessments offer a promising tool for informed marine spatial planning, designation...

  6. Redistributive effects of Swedish health care finance.

    Gerdtham, U G; Sundberg, G

    1998-01-01

    This paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: county council taxes, payroll taxes, direct payments and state grants. The redistributive effects are decomposed into vertical, horizontal and 'reranking' segments for each of the four financial sources. The data used are based on probability samples of the Swedish population, from the Level of Living Survey (LNU) from 1981 and 1991. The paper concludes that the Swedish health care financing system is weakly progressive, although direct payments are regressive. There is some horizontal inequity and 'reranking', which mainly comes from the county council taxes, since those tax rates vary for each county council. The implication is that, to some extent, people with equal incomes are treated unequally.

    The actual situation in our world can shortly be characterized by growing population and increasing energy demand, mainly covered by fossil fuels. This results in environmental as well as climate change problems. Renewable energies offer many opportunities to overcome these problems - they can provide heat and electricity as well as automotive fuels in environmentally friendly systems and thus contribute to lower the fossil fuels dependency. Biomass as the oldest renewable energy of mankind is still playing a dominant role as an energy carrier in some African and Asian regions, where biofuels are still used in traditional ways - mainly for cooking. On the other hand biomass has a huge potential to become a more important energy resource even in industrialized countries. All over the world the opportunities of biomass are accepted and biomass has become a common term in politics resulting in new strategic analyses, political documents, legislative actions and funding programs. A lot of modern and new high-tech solutions for bioenergy systems are already developed and others are under research. Aims of the actual developments are new bioenergy systems on the basis of regional biomass potentials in rural regions. The Baltic Sea Region offers a high potential to produce biofuels for different applications to fit the growing demand of heat, electricity and fuels. In combination with its industry and engineering skills the Baltic Sea Region is predestinated as a nucleus for further development and demonstration of advanced bioenergy solutions. In the result of the conference ''Contribution of Agriculture to Energy Production'', held in Tallinn, Estonia in October 2005 representatives from policy, economy and science identified a high potential and demand for bioenergy solutions and realized the necessity of establishment of an international network (Baltic Bioenergy Net - BaBEt) for information and know-how transfer between the Baltic States to foster the energetic use

    A particle-tracking model based on high-resolution ocean flow data was used to investigate particle residence times and spatial distribution of settling sediment for two geo-morphologically different Swedish coastal areas. The study was a part of a safety assessment for the location of a future nuclear-waste repository, and information about the particle-transport patterns can contribute to predictions of the fate of a possible leakage. It is also, to our knowledge, the first time particle-transport differences between two coastal areas have been quantified in this manner. In Forsmark, a funnel-shaped bay shielded by a number of islands, the average residence time for clay particles was 5 times longer than in the modeled part of Simpevarp, which is open to the Baltic Sea. In Forsmark, <10 % of the released particles left the domain compared to 60-80 % in Simpevarp. These site-specific differences will increase over time with the differences in land uplift between the areas.

    2017-10-01

    Geodiversity describes the heterogeneity of the physical terrain. We have performed basin-wide geodiversity analysis on a glaciated epicontinental seabed to assess geodiversity measures and patterns, locate areas with high geodiversity, and draw conclusions on contributing processes. Geodiversity quantification is a rather new topic and is mainly practiced in land areas. We applied geodiversity methods developed for terrestrial studies to a seabed environment. Three geodiversity parameters, including the richness, patchiness, and geodiversity index, of the Baltic Sea were assessed in a GIS environment based on broad-scale datasets on seabed substrates, structures, and bedrock. A set of environmental and geological variables, which were considered to reflect geological processes under seabed conditions, were compared with the geodiversity to identify some of its drivers. We observed differences in the geodiversity levels of the Baltic subbasins, which are mainly due to basement type/bedrock, roughness, shore density, and glacier-derived processes. The geodiversity of the Baltic Sea generally increases from South to North and from open-sea to high-shore density areas (archipelagos). Crystalline bedrock areas provide more diverse seabed environments than sedimentary rock areas. The analysis helps to inform scientists, marine spatial planners, and managers about abiotic conservation values, the dynamics of the seabed environment, and potential areas with elevated biodiversity.

  17. The Baltics on Their Way towards a Circular Economy

    Directory of Open Access Journals (Sweden)

    Grigoryan A. A.

    2017-10-01

    Full Text Available Circular economy has been studied extensively both in Europe and worldwide. It is largely viewed as a potential strategy for societal development, aimed to increase prosperity while reducing dependence on raw materials and energy. Many businesses regard circular economy as a way to enhance economic growth and increase profits. Governments across the world actively engage in the discussion about the benefits of a transition to a circular economy and about its impact on employment, economic growth, and the environment. This paper aims to study the major issues of circular economy, to identify its advantages, and to offer an insight into the transition stage the Baltic States are undergoing today on their way to circular economy. It is stressed that the Baltic countries are not fully using the opportunities offered by a circular economy. For example, Latvia’s, Lithuania’s, and Estonia’s recycling rates are significantly below those of other European countries. The Baltics depend heavily on EU financial support. An increase in funding will contribute to the implementation of circular economy technologies.

    While the use of electroconvulsive therapy (ECT) has been investigated worldwide, nothing is known about its use in the Baltic states. The purpose of this study was thus to explore ECT practice in the three Baltic countries. A 21-item, semi-structured questionnaire was sent out to all psychiatric inpatient settings that provided ECT in 2010. In Lithuania, four services provided ECT in 2010. Only modified ECT with anaesthesia and muscle relaxation is performed in the country. In 2010, approximately 120 patients received ECT, i.e., 0.375 patients/10,000 population. Only two centres offer ECT in Latvia. The first centre treated only three patients with ECT in 2010, while the second centre six patients. In both centres outdated Soviet machines are used. The main indication for ECT was severe, malignant catatonia. ECT is practiced in five psychiatric facilities in Estonia. In 2010, it was used in the treatment of 362 patients (17% women) nationwide, i.e., 2.78 patients/10,000 population. Only a senior psychiatrist may indicate ECT in Estonia and pregnancy is no contraindication. In 2010, the main indication for ECT was schizophrenia (47.8%). This 2010 survey revealed significant differences in the use and availability of ECT between the Baltic countries.

    The paper characterises the economic development of the Baltic countries after they have restored the independence. The authors explore the dynamic of the key economic indices - the GDP and inflation level, and show that there are tendencies for the economy to improve. The data on the direct foreign investments per capita are given for each Baltic country as well as on the greatest foreign firms - investors functioning in Latvia and the investment allocation among the sectors. The State Investment Programme realised in Latvia since 1996 is well illustrated, and the share is shown of the sectors involved. The authors briefly discuss legislative activities in the energy sector for Latvia, Lithuania and Estonia, and present statistical data on the energy supply in Baltic countries. The energy production and import/export balance is analysed, and the tariffs for electricity are exemplified for all the three countries. The information is also given as to the number of energy debtors and the distributors of the debts for consumed energy among separate branches of energetics in Latvia and Lithuania. The data presented in the paper show that due to decrease in energy resource consumption the harmful pollution have also diminished. (author)

  20. Bringing Western-standard service stations to the Baltic countries

    1992-01-01

    Neste is the only Western oil company so far to have established a service station presence in the Baltic, with the exception of Norway's Statoil, which has one outlet near Tallinn Airport. Neste has an important logistical advantage compared to other companies in this respect as its two Finnish refineries are ideally located for supplying the region with high-quality petroleum products. Neste's first joint venture in the Baltic, Traffic Service, based in Estonia, was set up with Eesti Kutus in 1988 and opened its first service station in 1990. Other joint ventures are now up and running in Latvia, Lithuania, Poland, and St. Petersburg. A total of 10 - 15 stations, the majority strategically located along the route of the Via Baltica, are expected to be operational by the end of this year. The Neste network comprises a combination of new outlets and refurbished older stations that have been modernized to bring them up to Western standards. These offer a comprehensive range of fuels, lubricants, spare parts, and accessories, as well as food, confectionery, and coffee shop services. Some stations also offer repair and car wash facilities. Adapting to the transition from a communist economy to a Western, capitalist one has not been easy for the Baltic countries, and has inevitably created difficulties for companies like Neste, in areas such as legislation covering land ownership. Neste's joint ventures have also encountered difficulties in instilling the Western approach to business efficiency, and customer service in a workforce used to the Soviet retail system

Meanwhile, Vietnam has one of the fastest-growing economies in South East Asia. However, there has not been any Swedish furniture company established on the Vietnamese market so far. Therefore, it would be useful to see if the Vietnamese furniture consumers would appreciate Swedish furniture, in order to analyze whether Swedish furniture companies...

    Full Text Available An extensive data series of salinity, nutrients and coloured dissolved organic material (CDOM was collected in the Skagerrak, the northern part of the Kattegat and off the Jutland west coast in April each year during the period 1996–2000, by the Institute of Marine Research in Norway. In this month, after the spring bloom, German Bight Water differs from its surrounding waters by a higher nitrate content and higher nitrate/phosphate and nitrate/silicate ratios. The spreading of this water type into the Skagerrak is of special interest with regard to toxic algal blooms. The quantification of the spatial distributions of the different water types required the development of a new algorithm for the area containing the Norwegian Coastal Current, while an earlier Danish algorithm was applied for the rest of the area. From the upper 50 m a total of 2227 observations of salinity and CDOM content have been used to calculate the mean concentration of water from the German Bight, the North Sea (Atlantic water, the Baltic Sea and Norwegian rivers. The Atlantic Water was the dominant water type, with a mean concentration of 79%, German Bight Water constituted 11%, Baltic Water 8%, and Norwegian River Water 2%. At the surface the mean percentages of these water types were found to be 68%, 15%, 15%, and 3%, respectively. Within the northern part of the Skagerrak, closer to the Norwegian coast, the surface waters were estimated to consist of 74% Atlantic Water, 20% Baltic Water, and 7% Norwegian River Water. The analysis indicates that the content of German Bight Water in this part is less than 5%.

These individuals were mainly immature and maturing stages with an increasing proportion of females to males with size. Salinity and oxygen conditions were found to be the major factors influencing...... the vertical and horizontal distribution of adult cod. Abundance of immature cod was also positively related to decreasing bottom depths. The effect of temperature was minor. The observed size- and sex-dependent spawning aggregation patterns, in association with habitat volume and stock size, may influence cod......The Baltic Sea is a stratified, semi-enclosed sea typified by a low-salinity surface layer and a deep saline layer of varying volume, salinity, temperature and oxygen concentration.

    Apart from the sediment as the dominant source of methane in the aquatic realm the process of methane production in well-oxygenated waters has received considerable attention during the last years. The paradox of methane accumulation in these relatively shallow waters, commonly termed as "oceanic methane paradox", has been sporadically observed in lakes as well as in marine ecosystems like the Gulf of Mexico, the Black Sea, the Baltic Sea, Arctic waters or above the continental shelf off the coast of Spain and Africa. Even if this phenomenon has been described in the literature over the last decades, the potential sources of shallow methane accumulation are still controversially discussed. We report on methane enrichments that were observed during summer in the upper water column of the Gotland Basin, central Baltic Sea. In the eastern part of the basin methane concentrations just below the thermocline (in about 30 m water depth) varied between 15 and 77 nM, in contrast to the western part of the basin where no methane enrichments could be detected. Stable carbon isotope ratios of methane (delta 13C-CH4 of -67.6‰) clearly indicated its in situ biogenic origin. This is supported by clonal sequences from the depth with high methane concentrations in the eastern Gotland Basin, which cluster with the clade Methanomicrobiacea, a family of methanogenic Archaea. Hydroacoustic observation in combination with plankton net tows displayed a seston enrichment (size >100 micro meter) in a layer between 30-50 m depth. The dominant species in the phytoplankton, Dinophysis norvegica, was concentrated at 10-20 m depth, and showed higher concentrations in the eastern Gotland Basin in comparison with the western part of the basin. In contrast to the western Gotland Basin, the zooplankton community in the eastern part was dominated by the copepod species Temora longicornis. Laboratory incubations of a T. longicornis dominated seston fraction (>100 micro meter) sampled in the depth

    The idea of coastDat is to improve the data base in sparse observational marine regions and to increase data homogeneity and consistency. In doing so long-term historical model data of e.g. wind (e.g. storms), wind wave and tide surge hindcasts are developed and proofed for regions like North Sea and Baltic Sea. These data-sets are available in hourly resolution and highly spatial resolution to simulate the marine environment from 1948/1958 up to now. Scenarios of potential future developments in a changing climate are also available. The coastDat data sets are used for applications e.g. offshore wind industry (design & logistics), risk analysis and analysis of pathways of energy transition. More than 80 stakeholders have used coastDat data sets. They are composed of science networks (31%), economic actors (45 %) and administrating policy actors (14%). The idea of coastDat is compatible in other coastal regions. Also coastDat is suitable as an information base in order to develop possible future adaptation measures. Here the data set and the history are briefly described, validation is reviewed, and an overview about recent uses of the data is provided.

    Manipulation of the blood's oxygen carrying capacity (CaO(2)) through reinfusion of red blood cells, injections of recombinant erythropoietin or by other means results in an increased maximal oxygen uptake and concomitantly enhanced endurance performance. Therefore, there is a need to establish a system--"A Blood Pass"--through which such illegal and unethical methods can be detected. Venous blood samples were taken under standardized conditions from 47 male and female Swedish national and international elite endurance athletes four times during the athletic year of the individual sport (beginning and end of the preparation period and at the beginning and during peak performance in the competition period). In these samples, different hematological values were determined. ON(hes) and OFF(hre) values were calculated according to the formula of Gore et al. A questionnaire regarding training at altitude, alcohol use and other important factors for hematological status was answered by the athletes. There were some individual variations comparing hematological values obtained at different times of the athletic year or at the same time in the athletic year but in different years. However, the median values of all individual hematological, ON(hes) and OFF(hre), values taken at the beginning and the end of the preparation or at the beginning and the end of the competition period, respectively, as well as median values for the preparation and competition periods in the respective sport, were all within the 95% confidence limit (CI) of each comparison. It must be mentioned that there was no gender difference in this respect. This study shows that even if there are some individual variations in different hematological values between different sampling times in the athletic year, median values of important hematological factors are stable over time. It must be emphasized that for each blood sample, the 95% CI in each athlete will be increasingly narrower. The conclusion is that

    1967-06-15

    Recent tracer investigations in Swedish steel plants have mainly dealt with problems concerning uon-metallic inclusions, slag weight determination and - labelling of special steel qualities for identification. Suspected inclusion sources, such as furnace slag, ladle-bottom mortar and some brick materials as stopper, nozzle.and channel bricks have been labelled radioactively in different ways. The labelling technique has been studied for the different systems and a new method was developed for brick materials. This includes vacuum impregnation with an aqueous solution of the inactive tracer, reheating to 1300 Degree-Sign C and neutron-irradiation in a reactor. A sufficiently homogeneous labelling of the material was obtained in this way. The tracer used was terbium, which was added as the nitrate and then decomposed to oxide during the heating process. The oxide is strongly bound to the ceramic material. The number of radioactive inclusions was determined by.autoradiography, and related to the total number pf inclusions, obtained by visual slag-counting, to give the percentage of inclusions originating from the labelled object. Some investigations have been made using simultaneous labelling of two or more sources. It seems to be difficult, however, to measure separately more than two tracers: one short-lived (e.g. 140La) and one long-lived (e.g. {sup 160}Tb). The slag weight determinations were made using the isotope dilution technique with {sup 131}Ba and {sup 140}La as tracers. A difference in slag weight is sometimes obtained. An attempt is made to explain these deviations. The material transport through a blast furnace has been followed by using a piece of graphite, labelled with {sup 140}La{sub 2}O{sub 3}, and measuring the radiation intensity outside the furnace walls and in the tuyere. Studies have been made to determine suitable radiotracers for labelling of steel for subsequent identification. Up to three different isotopes can be used simultaneously

    Local Agenda 21 (LA21) processes have 2 central goals. i) On the basis of some of the empirical evidence in this study, the primary goal is to improve democratic (environmental) policy-making processes in such a manner that a larger share of the population will be able to participate in planning and decision making and will also be able to understand the consequences of these decisions. ii) The LA21 processes seek to improve (at least indirectly) the broadly defined environmental situation locally in a manner that takes into account both the local and the global contexts. The first part of this article discusses the concept and methods of LA21 and sheds light on the different action areas that are central to the Baltic LA21 processes. In addition, the study will describe and display the LA21 situation within one network of cities, the Union of the Baltic Cities (UBC). Networking, including transfer of information, models and ideas, has been among the main tools for the diffusion of LA21 ideas especially into newly democratized societies. Finally, the article will conclude with an overall assessment of the LA21 situation on the Baltic rim.

    Tourism around the Oder (Szczecin) Lagoon, at the southern Baltic coast, has a long tradition, is an important source of income and shall be further developed. Insufficient bathing water quality and frequent beach closings, especially in the Oder river mouth, hamper tourism development. Monitoring data gives only an incomplete picture of Escherichia coli (E. coli) bacteria sources, spatial transport patterns, risks and does neither support an efficient bathing water quality management nor decision making. We apply a 3D ocean model and a Lagrangian particle tracking model to analyse pollution events and to obtain spatial E. coli pollution maps based on scenario simulations. Model results suggests that insufficient sewage treatment in the city of Szczecin is the major source of faecal pollution, even for beaches 20km downstream. E. coli mortality rate and emission intensity are key parameters for concentration levels downstream. Wind and river discharge play a modifying role. Prevailing southwestern wind conditions cause E. coli transport along the eastern coast and favour high concentration levels at the beaches. Our simulations indicate that beach closings in 2006 would not have been necessary according to the new EU-Bathing Water Quality Directive (2006/7/EC). The implementation of the new directive will, very likely, reduce the number of beach closings, but not the risk for summer tourists. Model results suggest, that a full sewage treatment in Szczecin would allow the establishment of new beaches closer to the city (north of Dabie lake). Copyright © 2013 Elsevier GmbH.

  15. The Role of Political Elites in the Development of Politics of Memory in the Baltic States

    2015-06-01

    Full Text Available The article focuses on multiple cases of the politicization of history by the Baltic political elites. Three states of development of politics of memory in the Baltic States are identified. Problems of political exploitation of the past are scrutinized in the context of political life and international relations. It is concluded that the narratives of the past where nazi and Soviet legacies are equated are actively promoted on the pan-European level. Elites of the Baltic States play a salient role in this process and enhance ties with the elites of the Eastern Europe, expert and political communities of the Western Europe and USA. The dominant trends in the development of the historical politics in the Baltic countries are the administrative and legislative instruments for approval of the preferred narratives of the past, as well as an active political work at the international level aimed at the inclusion of the Baltic narratives of the past into the European politics of memory. Historical politics of the Baltic States shows the Baltic countries as the victims of "two totalitarianisms" ("Nazi and Soviet occupation", and this point of view is widely used as a foreign policy tool. The politicization of the "anti-totalitarianism" issue is now a popular foreign policy tool that not only serves the interests of the Baltic and Eastern European politicians, but also finds ideological supporters in Western Europe and the United States.

  9. SWEDISH CRIME FICTION AS SOCIALLY INVOLVED LITERATURE

    Directory of Open Access Journals (Sweden)

    Monika Samsel-Chojnacka

    2011-01-01

    Full Text Available Swedish crime novel has been transforming for many years to become more socially involved. The ambition of many writers is not only to entertain the readers but also to participating in the social debate, criticizing the political and economical system, focusing on important issues such as violence against women, exploitation of working class by the privileged ruling class, the problems of a modern family and the situation of immigrants. Since the moment when in the mid 60’s two journalists Maj Sjöwall and Per Wahlöö decided to use popular literature to spread social matters many other Swedish writers have decided to follow their way. Some of them are journalists – like Liza Marklund, Börge Hellström and Anders Roslund or Stieg Larsson. Their novels as well as the ones written by Henning Mannkel on Kurt Wallander have become crucial evidence of changes of Swedish society in the past twenty years. Modern Swedish crime fiction illustrates the population in the model fashion that is the reason why it can become one of the interests of the sociology of literature.

  10. High-resolution measurements of elemental mercury in surface water for an improved quantitative understanding of the Baltic Sea as a source of atmospheric mercury

    Science.gov (United States)

    2018-03-01

    Marginal seas are directly subjected to anthropogenic and natural influences from land in addition to receiving inputs from the atmosphere and open ocean. Together these lead to pronounced gradients and strong dynamic changes. However, in the case of mercury emissions from these seas, estimates often fail to adequately account for the spatial and temporal variability of the elemental mercury concentration in surface water (Hg0wat). In this study, a method to measure Hg0wat at high resolution was devised and subsequently validated. The better-resolved Hg0wat dataset, consisting of about one measurement per nautical mile, yielded insight into the sea's small-scale variability and thus improved the quantification of the sea's Hg0 emission. This is important because global marine Hg0 emissions constitute a major source of atmospheric mercury. Research campaigns in the Baltic Sea were carried out between 2011 and 2015 during which Hg0 both in surface water and in ambient air were measured. For the former, two types of equilibrators were used. A membrane equilibrator enabled continuous equilibration and a bottle equilibrator assured that equilibrium was reached for validation. The measurements were combined with data obtained in the Baltic Sea in 2006 from a bottle equilibrator only. The Hg0 sea-air flux was newly calculated with the combined dataset based on current knowledge of the Hg0 Schmidt number, Henry's law constant, and a widely used gas exchange transfer velocity parameterization. By using a newly developed pump-CTD with increased pumping capability in the Hg0 equilibrator measurements, Hg0wat could also be characterized in deeper water layers. A process study carried out near the Swedish island Øland in August 2015 showed that the upwelling of Hg0-depleted water contributed to Hg0 emissions of the Baltic Sea. However, a delay of a few days after contact between the upwelled water and light was apparently necessary before the biotic and abiotic transformations

  12. Artistic Alliances and Revolutionary Rivalries in the Baltic Art World, 1890-1914

    Directory of Open Access Journals (Sweden)

    Bart Pushaw

    2016-11-01

    Full Text Available In the areas now known as Estonia and Latvia, art remained a matter for the Baltic German minority throughout the nineteenth century. When ethnic Estonian and Latvian artists gained prominence in the late 1890s, their presence threatened Baltic German hegemony over the region’s culture. In 1905, revolution in the Russian Empire spilled into the Baltic Provinces, sparking widespread anti-German violence. The revolution also galvanized Latvian and Estonian artists towards greater cultural autonomy and independence from Baltic German artistic institutions. This paper argues that the situation for artists before and after the 1905 revolution was not simply divisive along ethnic lines, as some nationalist historians have suggested. Instead, this paper examines how Baltic German, Estonian and Latvian artists oscillated between common interests, inspiring rivalries, and politicized conflicts, questioning the legitimacy of art as a universalizing language in multicultural societies.

    Environmental Impact Assessment (EIA) in the Baltic Countries: The Case of Three Oil Terminals is the second phase of a research and exchange project that has been going on between Baltic and Nordic experts on Environmental Impact Assessment since 1992. The objective of the projects is to contribute to the capability of the Baltic states in carrying out EIAs. By scrutinizing the processes of the EIAs carried out for three Baltic oil terminals, working groups consisting of both Nordic and Baltic EIA experts have sought to highlight the practical implications of the `EIA vocabulary` eagerly taught by Western experts and perhaps even more eagerly studied by their `Eastern` counterparts during the last few years. The three cases were: Lithuania, Oil Port of Klaipeda; Latvia, Oil Terminal in Liepaja; Estonia, Muuga Port. (au)

  14. Processing Relative Clause Extractions in Swedish

    Directory of Open Access Journals (Sweden)

    Damon Tutunjian

    2017-12-01

    Full Text Available Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE, raising the possibility that island constraints may be subject to “deep variation” between languages. One alternative is that such exceptions are only illusory and represent “surface variation” attributable to independently motivated syntactic properties. Yet, to date, no surface account has proven tenable for Swedish RCEs. The present study uses eyetracking while reading to test whether the apparent acceptability of Swedish RCEs has any processing correlates at the point of filler integration compared to uncontroversial strong island violations. Experiment 1 tests RCE against licit that-clause extraction (TCE, illicit extraction from a non-restrictive relative clause (NRCE, and an intransitive control. For this, RCE was found to pattern similarly to TCE at the point of integration in early measures, but between TCE and NRCE in total durations. Experiment 2 uses RCE and extraction from a subject NP island (SRCE to test the hypothesis that only non-islands will show effects of implausible filler-verb dependencies. RCE showed sensitivity to the plausibility manipulation across measures at the first potential point of filler integration, whereas such effects were limited to late measures for SRCE. In addition, structural facilitation was seen across measures for RCE relative to SRCE. We propose that our results are compatible with RCEs being licit weak island extractions in Swedish, and that the overall picture speaks in favor of a surface rather than a deep variation approach to the lack of island effects in Swedish RCEs.

  15. Prevalence of footrot in Swedish slaughter lambs

    Directory of Open Access Journals (Sweden)

    Nyman Ann-Kristin J

    2011-04-01

    Full Text Available Abstract Background Footrot is a world-wide contagious disease in sheep and goats. It is an infection of the epidermis of the interdigital skin, and the germinal layers of the horn tissue of the feet. The first case of footrot in Swedish sheep was diagnosed in 2004. Due to difficulties in distinguishing benign footrot from early cases of virulent footrot and because there is no possibility for virulence testing of strains of Dichelobacter nodosus in Sweden, the diagnosis is based of the presence or absence of clinical signs of footrot in sheep flocks. Ever since the first diagnosed case the Swedish Animal Health Service has worked intensively to stop the spread of infection and control the disease at flock level. However, to continue this work effectively it is important to have knowledge about the distribution of the disease both nationally and regionally. Therefore, the aims of this study were to estimate the prevalence of footrot in Swedish lambs at abattoirs and to assess the geographical distribution of the disease. Methods A prevalence study on footrot in Swedish lambs was performed by visual examination of 2000 feet from 500 lambs submitted from six slaughter houses. Each foot was scored according to a 0 to 5 scoring system, where feet with score ≥2 were defined as having footrot. Moreover, samples from feet with footrot were examined for Dichelobacter nodosus by culture and PCR. Results The prevalence of footrot at the individual sheep level was 5.8%, and Dichelobacter nodosus was found by culture and PCR in 83% and 97% of the samples from feet with footrot, respectively. Some minor differences in geographical distribution of footrot were found in this study. Conclusions In a national context, the findings indicate that footrot is fairly common in Swedish slaughter lambs, and should be regarded seriously.

    Presence of thin synthetic fibres (microfibres, tens of micrometres in diameter) in the surface waters and sediments is documented in different studies; however, the data on their exact abundances in the marine environment are commonly not presented owing to the shortcomings of the sampling procedure and general absence of well-established methodology for microplastics data collection. Nevertheless, we made an attempt to qualitatively analyse the amounts of microplastic fibres in the water column of the Baltic Sea. Water samples acquired during 6 cruises over the Baltic Sea Proper in 2015-2016 were filtered using 174 μm filters, which were subsequently analysed by microscope. From the total of 95 examined filters, 63% contained fibres. They were identified by colour and the reaction to the mechanical action of a thin needle: justification of anthropogenic origin was considered to be enough; any questionable objects were discarded. Fibres comprise more than 90% of the whole microplastic particles found in the near-bottom layers in the coastal zone and around 24% of microplastics in the surface and intermediate waters, with mean concentrations of 0.71 and 0.07 fibres per litre, respectively. Although the methodology still requires a lot of enhancement, even the preliminary results indicate ubiquitous distribution of the microfibres in the water column of the Baltic Sea with surface and bottom layers revealing higher abundances of microfibres in comparison with intermediate layers, and open-sea waters being less contaminated than the coastal ones. Apart from enhancing the sampling technics, we consider that it is crucial to understand principal physical features of fibers behavior in the marine environment (e.g., settling, entrainment by currents), as it would provide an opportunity to parameterize their transport and further on to model distribution of fibers in the water column.

    2017-09-01

    Calculations related to the marine CO2 system that are based on alkalinity data may be strongly biased if the contributions of organic compounds are ignored. In coastal seas, concentrations of dissolved organic matter (DOM) are frequently high and alkalinity from inorganic compounds is low. In this study, based on measurements of total alkalinity, total CO2, and pH, we determined the organic alkalinity, Aorg, in water from the central Baltic Sea. The maximum Aorg measured in the surface mixed layer during the spring bloom was > 50 μmol/kg-SW but the Aorg decreased with depth and approached zero below the permanent halocline. This behavior could be attributed to the decreased pH of deeper water layers. The data were used to calculate the bulk dissociation constant, KDOM, for marine DOM and the fraction f of dissolved organic carbon (DOC) that acts as a carrier for acid-base functional groups. The p KDOM (7.27) agreed well with the value (7.34) previously estimated in a preliminary study of organic alkalinity in the Baltic Sea. The fraction of carbon atoms carrying acid-base groups was 17% and was somewhat higher than previously reported (12%). Spike experiments performed using artificial seawater and three different humic/fulvic substances tested whether the acid-base properties of these substances explain the results of our field study. Specifically, Aorg was determined at different concentrations (DOC) of the added humic/fulvic substances. The relationship between Aorg and the DOC concentrations indicated that humic/fulvic substances are more acidic (p KDOM < 6.5) than the bulk DOC natural occurring in the Baltic Sea.

    2006-01-01

    This paper analyses the use of renewable energy sources (RES) dedicated mainly for electricity generation in the Baltic countries (Estonia, Latvia and Lithuania). Hydropower sector including both large (medium) and small power plants is particularly considered. The region has very limited energy resources of its own and is heavily dependent on the import of the primary energy sources (in some way except Estonia). The main objective of energy policy of the Baltic countries is to reduce such a total dependence by favouring the use of RES. A brief description of energy sector is given, focusing on electricity generation. RES potential currently in use and to be exploited in the future, buy- back rates of the key sources are presented. The countries' target broken down according to the individual RES to meet the EU 'green' electricity directive (2001/77/CE) are presented. Small and large hydropower potential is analyzed, a general overview of hydro-plants in operation and planned schemes is provided. A particular attention is devoted to environmental and social aspects of hydropower development. The requirements of the protected areas in relation to dam construction are analyzed, an estimation of resistance to small hydropower development is shown. The environmental legislation including forbidden rivers for damming actually in force in the Baltic countries is considered; hydropower image perceptible by general public, NGOs and official environmental bodies are discussed. The causes and legal basis of the promulgation of the list of forbidden rivers are revealed. A conclusion is drawn that the contradiction between two EU legal frameworks - environmental protection and promotion of renewables, in the case of hydropower, exists. The evaluation of the quantitative impact of the forbidden rivers on small hydropower resources in Lithuania proves. the environmental legislation is one of the strictest in the European countries.

    Full Text Available The 2008–09 global crisis raised debates concerning the determinants of financial vulnerability. Among these, bad loans have been identified as significantly influencing financial imbalances. After a decade in which borrowing has constantly grown mainly because of the deregulation of financial markets, the crisis highlighted the importance of an effective credit risk management. The purpose of the paper is to study the evolution of bad loans ratio in relation with selected macroeconomic indicators in the Baltic countries (Estonia, Latvia and Lithuania and Romania.

    Reducing anthropogenic nutrient inputs is a major policy goal for restoring good environmental status of coastal marine ecosystems. However, it is unclear to what extent reducing nutrients would also lower fish production and fisheries yields. Empirical examples of changes in nutrient loads...... and concurrent fish production can provide useful insights to this question. In this paper, we investigate to what extent a multi-fold increase in nutrient loads from the 1950s to 1980s enhanced forage fish production in the Baltic Sea. We use monitoring data on fish stock dynamics covering the period...

    Sweden has a population of a little more than 9.4 million. The rapid growth of immigration in Sweden has resulted in an increased number of minority ethnic patients and minority ethnic nurses in the Swedish healthcare system. This also applies to paediatric care. The purpose of this study was to explore how parents with ethnic Swedish backgrounds experience minority ethnic nurses' cultural competence and the care the nurses provide in a Swedish paediatric care context. This exploratory qualitative study is of 14 parents with an ethnic Swedish background whose child was in a ward at a children's hospital in Stockholm County Council. Data were collected using semi-structured interviews to identify parents' perceptions and experiences of minority ethnic nurses' cultural competence. The interviews were analysed by qualitative content analysis. The analyses of the interviews led to four main categories: influence of nurses' ethnicity; significance of cross-cultural communication; cross-cultural skills; and the importance of nursing education. Nurses' ethnicity did not have much impact on parents' satisfaction with their child's care. The parents attached importance to nurses' language skills and to their adaptation and awareness of Swedish culture. They also attached weight to nurses' professional knowledge and personal attributes. The role of nursing education to increase nurses' cultural awareness was highlighted too. © 2013 Nordic College of Caring Science.

    1997-01-01

    One of the things that makes life both very frustrating and also very interesting is that accomplishing one objective frequently means backpedaling on another. Since economics is the study of tradeoffs, this means that there is generally plenty for economists to do. William Nordhaus is one of the best economists anywhere, and he has written a wonderful book about the tradeoffs faced by one country--Sweden--if and as it acts on a decision its citizens made in 1980 to phase out the use of nuclear power there. The author adds that this decision has been reaffirmed by the Swedish Parliament on several occasions since the 1980 referendum, though with some elusive qualifications. What will be both the environmental and also the economic implications of a Swedish phaseout of the use of nuclear power to generate electricity there. These are the two issues Nordhaus addresses in this book

    1999-01-01

    The environmental monitoring programme for the nuclear facilities has shown that the radioactive discharges increase the concentrations of some radionuclides in the local marine environment around the Swedish nuclear facilities. Samples from the terrestrial environment rarely show increased radionuclide concentrations. From a radiological point of view the most important nuclide in the environmental samples usually is CS-137. However, the largest part of the present concentrations of Cs-137 in the Swedish environment originate from the Chernobyl accident. The concentrations of radionuclides that can be found in biota around the nuclear facilities are much lower than the concentration levels that are known to give acute damage to organisms. The total radiation doses from the discharges of radionuclides are small. (au)

    The aim of this paper is to provide an overview of traumatic stress studies from the three Baltic countries-Lithuania, Latvia, and Estonia-and reveal how specific social context contributes to the topics relevant in traumatic stress field in the region. Traumatic stress studies in the Baltic countries are closely related to the complicated history of the region. It was only since the restoration of independence of the Baltic States in the 1990s when traumatic stress studies could emerge. The start of the psychotraumatology in the Baltic States was inspired by the interest of the psychological effects of political violence. Four major topics in traumatic stress literature from the Baltic countries were identified in this article: political violence studies, epidemiology of trauma and posttraumatic stress disorder (PTSD), disaster studies, and developmental aspects of trauma. Traumatic events prevalence was reported between 70 and 75%, and PTSD prevalence range 2-7% in the Baltic countries. The interest in psychotraumatology in the Baltic countries is rising.

    Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE), raising the possibility that island constraints may be subject to “deep variation” between languages. One alternative is that such exceptions are only illusory and represent “surface variation” attributable to independently motivated syntactic properties.

    The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

    2008-11-06

    This study aims at the estimation of the impact of different atmospheric factors on the past sealevel variations (up to 200 years) in the Baltic Sea by statistically analysing the relationship between Baltic Sea level records and observational and proxy-based reconstructed climatic data sets. The focus lies on the identification and possible quantification of the contribution of sealevel pressure (wind), air-temperature and precipitation to the low-frequency (decadal and multi-decadal) variability of Baltic Sea level. It is known that the wind forcing is the main factor explaining average Baltic Sea level variability at inter-annual to decadal timescales, especially in wintertime. In this thesis it is statistically estimated to what extent other regional climate factors contribute to the spatially heterogeneous Baltic Sea level variations around the isostatic trend at multi-decadal timescales. Although the statistical analysis cannot be completely conclusive, as the potential climate drivers are all statistically interrelated to some degree, the results indicate that precipitation should be taken into account as an explanatory variable for sea-level variations. On the one hand it has been detected that the amplitude of the annual cycle of Baltic Sea level has increased throughout the 20th century and precipitation seems to be the only factor among those analysed (wind through SLP field, barometric effect, temperature and precipitation) that can account for this evolution. On the other hand, precipitation increases the ability to hindcast inter-annual variations of sea level in some regions and seasons, especially in the Southern Baltic in summertime. The mechanism by which precipitation exerts its influence on Baltic Sea level is not ascertained in this statistical analysis due to the lack of long salinity time series. This result, however, represents a working hypothesis that can be confirmed or disproved by long simulations of the Baltic Sea system - ocean

    2013-06-01

    Full Text Available This article examines cooperation in the electric energy sector in the Baltic region. The author explores the existing undersea HVDC power exchange projects. It is emphasised that cooperation in the electric energy sector is concentrated largely in the EU member states despite earlier plans to establish the Baltic energy ring, which would also include Russia and Belarus. The author stresses that one of the most acute problems for the EU today is overcoming isolation of the energy systems of the Baltic States (Lithuania, Latvia, and Estonia from that of the major part of the EU. This task has become especially relevant after the closing of the Ignalina NPP (Lithuania, which used to be the primary energy source for the three Baltic States. The article examines key projects of the construction of new international power transmission lines in the framework of the Baltic Energy Market Interconnection Plan (BEMIP and the prospects of the Visaginas NPP (Lithuania in solving energy problems of the Baltic States. The author analyses Russia’s role in the electric energy market and focuses on a possible increase of the country’s energy market share following the construction of the Baltic NPP and the export of generated electric energy to Poland, Lithuania, Germany, and Sweden. The author concludes that the prospects of Russia’s energy export to the Baltic Sea region will be determined not only by technological, economic and market factors, but rather by the general state of relations between Russia and the EU. Moreover, a lot depends on Lithuania’s decision on the construction of the Visaginas NPP, as well as the way the EU and the Baltic States solve the problem of energy supply in case the NPP project is terminated.

    Global health education is increasingly acknowledged as an opportunity for medical schools to prepare future practitioners for the broad health challenges of our time. The purpose of this study was to describe the evolution of global health education in Swedish medical schools and to assess students' perceived needs for such education. Data on global health education were collected from all medical faculties in Sweden for the years 2000-2013. In addition, 76% (439/577) of all Swedish medical students in their final semester answered a structured questionnaire. Global health education is offered at four of Sweden's seven medical schools, and most medical students have had no global health education. Medical students in their final semester consider themselves to lack knowledge and skills in areas such as the global burden of disease (51%), social determinants of health (52%), culture and health (60%), climate and health (62%), health promotion and disease prevention (66%), strategies for equal access to health care (69%) and global health care systems (72%). A significant association was found between self-assessed competence and the amount of global health education received (pcurriculum. Most Swedish medical students have had no global health education as part of their medical school curriculum. Expanded education in global health is sought after by medical students and could strengthen the professional development of future medical doctors in a wide range of topics important for practitioners in the global world of the twenty-first century. © 2015 the Nordic Societies of Public Health.

    Recent prospective studies of male reproductive health have shown differences between several European countries. Our objective was to evaluate the current situation in the two Baltic States Estonia and Lithuania. In 1997-99 we investigated semen parameters, levels of reproductive hormones and general health factors of 196 men from the general population in Lithuania; from Estonia, 79 men from the general population and 118 soldiers were investigated. Adjusted for interlaboratory differences and abstinence period, sperm concentration of Lithuanian and Estonian men from the general populations were shown to be 55 and 67 million/mL, respectively. The Estonian soldiers had the highest sperm concentration, 82 million/mL. The frequencies of morphologically normal spermatozoa were 6.2, 7.7 and 9.6%, respectively. In contrast to the semen qualities, highest Inhibin B levels were detected in the Lithuanians (233 pg/mL) followed by Estonian men from the general population (220 pg/mL) and Estonian soldiers (185 pg/mL). The soldiers had also the lowest level of testosterone and oestradiol. The sperm counts of the Estonian and Lithuanian men investigated here are higher than recently shown for Norwegian, Danish, Estonian and Finnish men. Comparisons should be cautiously drawn as the groups are not completely comparable. Still, even within the Baltic region, geographically close and sharing common recent social history, differences in semen quality and levels of reproductive hormones are apparent.

    Today, the three Baltic countries Estonia, Latvia and Lithuania, have well-known medical faculties with international standing. Their individual histories are briefly outlined. However, relations of the German academic world were closest with the university of Dorpat (today: Tartu). It was re-opened in 1802 by tsar Alexander I in order to keep young Baltic people from studying abroad. The medical faculty was its biggest faculty. The university was Russian, but the official language was German. So many a German professor came to Dorpat and many professors from Dorpat were offered a chair at a German university. The scientific imports connected Dorpat with other centres of West-European science, they brought knowledge and ideas and an exchange of information. The standard was high, and among the teaching staff was a handsome number of medical celebrities, e.g. the anatomist August Rauber and the surgeon Ernst von Bergmann. In Dorpat, Rudolf Buchheim brought a new science, experimental pharmacology, into being, which his pupil and successor, Oswald Schmiedeberg, fully established and propagated all over the world.

    Full Text Available Next to the employee productivity or indicators for staff turnover and absenteeism in organizations, Employee Engagement stands out as one of the most significant measurements for Human Resource Management efficiency. With younger generation representatives joining the workforce companies are bound to investigate and pursue some of the new tools and techniques that respond more effectively to engagement triggers of generations Y and Z. At AirBaltic Corporation in Riga, Latvia, management has been trying to foster engagement of the workforce through introduction of a business game, called Forecaster. According to management belief, in addition to improved internal communication, Forecaster has potential to save up to 1 million eur annually due to the resulting better quality management decisions. Within the article author looks at the theory and research related to application and effects of gamification within corporate settings, as well as reviews workplace environment at AirBaltic Corporation. Further in the article, Forecaster game is described in more detail and its impact on employee engagement and organizational performance is analysed. Finally, recommendations are drawn for organizations to consider when gamifying people management processes in their organizations.

  1. Renewable Energy in the Baltic States. Different Situations

    2007-01-01

    In many ways, the Baltic nations seem to be good students with ambitious objectives for applying European directives and the Kyoto Protocol. For example, in 2006, renewable energies already accounted for 9 % in Lithuania, 10 % in Estonia and 43 % in Latvia (5.2 % in the EU-15) of primary energy output. This should increase to 12 %, 15 % and 50 % in 2010 (12 % in the EU-15) respectively. While all are dependent on oil imports, their own resources vary: nuclear power in Lithuania (at least until 2009 when the last reactor of the Ignalina power station will close, with EU compensation), oil shale feeds Estonian power stations, wood in Latvia. The latter must import electricity while the two other countries produce double their domestic demand. All three are linked to the Russian power grid built up during the Soviet era rather than the European. Nevertheless, the share of renewable energy produced electricity is very small in these two producer countries, unlike Latvia which has hydraulic resources. The three countries have very different taxation on energy and electrical products, including renewable energy price support. All were granted transitional periods of differing lengths to apply European standard. The Baltic nations produce low greenhouse gas emissions and only Estonia has organized an emission rights trading market

    Climate change is likely to have large effects on the Baltic Sea ecosystem. Simulations indicate 2-4 °C warming and 50-80 % decrease in ice cover by 2100. Precipitation may increase ~30 % in the north, causing increased land runoff of allochthonous organic matter (AOM) and organic pollutants and decreased salinity. Coupled physical-biogeochemical models indicate that, in the south, bottom-water anoxia may spread, reducing cod recruitment and increasing sediment phosphorus release, thus promoting cyanobacterial blooms. In the north, heterotrophic bacteria will be favored by AOM, while phytoplankton production may be reduced. Extra trophic levels in the food web may increase energy losses and consequently reduce fish production. Future management of the Baltic Sea must consider the effects of climate change on the ecosystem dynamics and functions, as well as the effects of anthropogenic nutrient and pollutant load. Monitoring should have a holistic approach, encompassing both autotrophic (phytoplankton) and heterotrophic (e.g., bacterial) processes.

    The introduction into the Baltic Sea of hazardous substances that are persistent, bioaccumulate, and are toxic is an important environmental and human health problem. Multilateral efforts to address this problem have primarily been taken under the Helsinki Commission (HELCOM). This article examines past HELCOM efforts on hazardous substances, and discusses future challenges regarding their management. The article finds that past actions on hazardous substances have had a positive effect on improving Baltic environmental quality and reducing human health risks, although there are remaining issues and difficulties that need to be addressed. In particular, four related future challenges for HELCOM management of hazardous substances are identified and discussed: i) the need to engender further implementation and building public and private sector capacities; ii) the need to improve data availability, quality and comparability across the region and international fora; iii) the need to strengthen existing regulations and incorporate new issues; and iv) the need to effectively coordinate HELCOM activities with efforts on hazardous substances in other international fora.

    The report presents summary of data on the Baltic Sea radioactive contamination obtained in DDR, PPR and the USSR within 1976-1980. The seawater, sediments and aquatic plants and animals were investigated. The distribution of strontium-90 and cesium-137 isotopes is given both for the open sea and its gulfs. Tendency towards strontium-90 concentration decrease is noted though cesium-137 concentration rise was observed in 1980 due to radioactive and polluted water ingress from the Northern Sea. In a number of points, except western regions in the vicinity of the Northern Sea, uniform distributions of strontium-90 and cesium-137 concentations versus depth were established. The radionuclide contents in water, sediments and aquatic organisms of Greifswald and Finland gulfs where Nuclear Power Plants are located on the seashore were found to be the same as in the open sea. The dependence of strontium-90 and especially cesium-137 sorption on the sediments composition has been noticed. In 1980 DDR presented data on tritium content in both near-surface and deep waters. Poland has carried out the first investigations of plutonium-239 and 240 content in the sediments. The dynamic behaviour of strontium-90 and cesium-137 concentrations in the Baltic Sea water within 1959-1980 has been reviewed. Data on strontium-90 and cesium-137 content in fishes and plants are given. On this basis the dose commitmments for population were estimated. 19 refs.; 27 tabs.; 6 figs

    The Nordic Geodetic Commission (NKG) has launched a joint NKG GNSS Analysis Centre that aims to routinely produce high qualityGNSS solutions for the common needs of the NKG and the Nordic and Baltic countries. A consistent and densified velocity field is needed for the constraining of the gla-cial isostatic adjustment (GIA) modelling that is a key component of maintaining the national reference frame realisations in the area. We described the methods of the NKG GNSS Analysis Centre including the defined processing setup for the local analysis centres (LAC) and for the combination centres.We analysed the results of the first 2.5 years (2014.5-2016). The results showed that different subnets were consistent with the combined solution within 1-2 mm level. We observed the so called network effect affecting our reference frame alignment. However, the accuracy of the reference frame alignment was on a few millimetre level in the area of the main interest (Nordic and Baltic Countries). TheNKGGNSS AC was declared fully operational in April 2017.

  6. Adaptive governance of the Baltic Sea - lessons from elsewhere

    Full Text Available Governance of marine resources is increasingly characterized by integrated, cross sectoral and ecosystem based approaches. Such approaches require that existing governing bodies have an ability to adapt to ecosystem dynamics, while also providing transparent and legitimate outcomes. Here, we investigate how the Baltic Marine Environment Protection Commission (HELCOM, the international governing body for the Baltic Sea, could improve its prospects for working with the ecosystem approach, drawing from the literature on adaptive governance. We construct an ideal type of adaptive governance to which we compare the way in which HELCOM is operating and relate these dynamics to two other international marine environment governance organizations, the Coral Triangle Initiative on Coral Reefs, Fisheries and Food Security (CTI-CFF and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR. We conclude that HELCOM deviates from an ideal type of adaptive governance in several ways but also that the other two case studies provide empirical support for potential ways in which HELCOM could improve its adaptive capacity. Key aspects where HELCOM could improve include increasing stakeholder participation – both in information sharing and decision making. Further, HELCOM need to develop evaluation mechanisms, secure compliance to improve adaptive capacity and organizational effectiveness, which entails the development of structures for conflict resolution. Finally, HELCOM need to increase communication and harmonization between different levels of authority.

  7. Modelling PCB bioaccumulation in a Baltic food web

    2007-01-01

    A steady state model is developed to describe the bioaccumulation of organic contaminants by 14 species in a Baltic food web including pelagic and benthic aquatic organisms. The model is used to study the bioaccumulation of five PCB congeners of different chlorination levels. The model predictions are evaluated against monitoring data for five of the species in the food web. Predicted concentrations are on average within a factor of two of measured concentrations. The model shows that all PCB congeners were biomagnified in the food web, which is consistent with observations. Sensitivity analysis reveals that the single most sensitive parameter is log K OW . The most sensitive environmental parameter is the annual average temperature. Although not identified amongst the most sensitive input parameters, the dissolved concentration in water is believed to be important because of the uncertainty in its determination. The most sensitive organism-specific input parameters are the fractional respiration of species from the water column and sediment pore water, which are also difficult to determine. Parameters such as feeding rate, growth rate and lipid content of organism are only important at higher trophic levels. - The bioaccumulation behaviour of PCB congeners in a Baltic food web is studied using a novel mechanistic model

    Full Text Available The paper focuses on the variation of institutional confidence in the Baltic countries. Within of framework of qualitative comparative framework, it employs a historical approach to detect causes of divergence of trust in rule of law institutions between Estonia vis-à-vis other two Baltic states. While it observes a range of variables that could affect the differences, it emphasises the role of political leadership during critical junctures, which might explain both why Estonia forged ahead at the outset of the post-communist transformation and most recent positive developments in the Baltic countries since the financial crisis in 2008–2010.

    2014-12-15

    We explore the possibilities for spontaneous formation of surface patches with high concentrations of contaminants through time correlations of the convergence field and the Lagrangian transport. The test area is the Gulf of Finland, the Baltic Sea, where surface velocity fields show extensive convergence. The flow properties are extracted from 3D velocity fields simulated for 1987-1991 using the OAAS model with a resolution of 1 mile. The focus is on the spatial distribution of the areas in which the values of finite-time flow compressibility of surface velocity fields exceed the threshold for clustering of floats. The distribution of such areas is asymmetric, with likely areas of patch formation located predominantly in the southern and eastern regions of the gulf. Out of nine areas of likely patch formation, six are located along the coast in regions of frequent downwelling, while three are identified in the central region of the gulf.

    In the Swedish nuclear power industry staff, very few newly employed have a deep education in reactor technology. To remedy this, a joint education company, Nuclear Training and Safety Center (KSU), has been formed. To ensure that nuclear competence will be available also in a long-term perspective, the Swedish nuclear power industry and the Swedish Nuclear Power Inspectorate (SKI) have formed a joint center for support of universities, the Swedish Nuclear Technology Center (SKC). The activities of these organisations, their links to universities, and their impact on the competence development for the nuclear power industry will be outlined. (author)

    Characterization of natural fracture and fault pattern play significant role for reservoir stimulation design and evaluation of its results. Having structural observations limited to immediate borehole surrounding it is a common need to build up a fracture model of reservoir in a range of stimulation reservoir volume or even beyond. To do this we need both a 3D seismic model and a consistent concept of the regional tectonic evolution. We present the result of integrated tectonic study in several deep boreholes target the Lower Paleozoic shale complex of Baltic Basin (BB), combined with analysis of 3D seismic survey and outcrop screening in Scania (Swedish part of the BB). During deposition of shale complex in the Ordovician and Silurian the research area was located 200-300 km away from the continental margin of Baltica involved in the Caledonian collision with the Eastern Avalonia. This distance allowed the shale complex to avoid significant tectonic deformation. Regional seismic cross section reveals the general pattern of the BB infill characteristic for the foreland basin underwent post-collisional isostatic rebound. Due to stress changes in collisional context the shale complex was cross-cut by steep, mostly inverse faults trending NW-SE and NE-SW. The fault zones oriented NW-SE are associated with an array of en echelon faults characteristic for strike-slip displacement. In our interpretation, these faults of Silurian (Wenlock) age create pattern of the regional pop-up structure, which is simultaneously involved in the plate flexure extension. Seismic attributes (e.g. curvature or ant tracking) highlight lineaments which mostly mimic the faults orientation. However, attributes show also some artefacts that come from regular array of seismic sources and receivers, which mimic the orthogonal joint system. Structural observations on borehole core lead us to conclusion that regular, orthogonal fracture system developed after maximum burial of the complex

    Baltic Sea is well known as the most polluted sea in the world, but its fish products have a significant role in diet of Baltic countries habitants. In Dioxin 2003 meeting we have present first results of analysis of Baltic fishes caught by Russian fisherman for market. The results confirmed a rather high level of pollution in the Baltic seafood by PCDD/Fs and have shown necessity of the further researches. Although PCDD/Fs profile in fisher's body is not consist unsteady and was formed under affection of various factors, it was obvious that essential path comes with PCB; also previously were found that WHO-TEQ{sub PCB} in seafood could exceed WHO-TEQ{sub PCDD/F} level. In given works we present results of the analysis of two freshwater species of fishes and updating research of former analyzed kinds, included of WHO-PCBs determination.

    Hypoxia is a well-described phenomenon in the offshore waters of the Baltic Sea with both the spatial extent and intensity of hypoxia known to have increased due to anthropogenic eutrophication, however, an unknown amount of hypoxia is present in the coastal zone. Here we report on the widespread unprecedented occurrence of hypoxia across the coastal zone of the Baltic Sea. We have identified 115 sites that have experienced hypoxia during the period 1955-2009 increasing the global total to ca. 500 sites, with the Baltic Sea coastal zone containing over 20% of all known sites worldwide. Most sites experienced episodic hypoxia, which is a precursor to development of seasonal hypoxia. The Baltic Sea coastal zone displays an alarming trend with hypoxia steadily increasing with time since the 1950s effecting nutrient biogeochemical processes, ecosystem services, and coastal habitat.

    Full Text Available The paper examines flows of foreign direct investment within the Baltic region. The author demonstrates close investment ties among the EU members, which are of special importance for Estonia, Latvia and Lithuania. Transborder corporate integration in the region is characterized by significant imbalances. In many aspects, it can be viewed as Sweden’s economic expansion or development of domestic markets for northern European companies. Although many German, Polish and Russian companies are involved in corporate integration in the Baltic region, other vectors of their foreign economic relations are still more important for them. As a result, the integration of Russian business in the Baltic part of the European integration area is still rather weak despite Russia’s considerable foreign direct investment in the Baltic States.

    Studies on dissolved silicate (DSi) and biogenic silica (BSi) dynamics were carried out in the Oder estuary, Baltic Sea in 2000-2005. The Oder estuary proved to be an important component of the Oder River-Baltic Sea continuum where very intensive seasonal DSi uptake during spring and autumn, but also BSi regeneration during summer take place. Owing to the regeneration process annual DSi patterns in the river and the estuary distinctly differed; the annual patterns of DSi in the estuary showed two maxima and two minima in contrast to one maximum- and one minimum-pattern in the Oder River. DSi concentrations in the river and in the estuary were highest in winter (200-250 μmol dm - 3 ) and lowest (often less than 1 μmol dm - 3 ) in spring, concomitant with diatom growth; such low values are known to be limiting for new diatom growth. Secondary DSi summer peaks at the estuary exit exceeded 100 μmol dm - 3 , and these maxima were followed by autumn minima coinciding with the autumn diatom bloom. Seasonal peaks in BSi concentrations (ca. 100 μmol dm - 3 ) occurred during the spring diatom bloom in the Oder River. Mass balance calculations of DSi and BSi showed that DSi + BSi import to the estuary over a two year period was 103.2 kt and that can be compared with the DSi export of 98.5 kt. The difference between these numbers gives room for ca. 2.5 kt BSi to be annually exported to the Baltic Sea. Sediment cores studies point to BSi annual accumulation on the level of 2.5 kt BSi. BSi import to the estuary is on the level of ca. 10.5 kt, thus ca. 5 kt of BSi is annually converted into the DSi, increasing the pool of DSi that leaves the system. BSi concentrations being ca. 2 times higher at the estuary entrance than at its exit remain in a good agreement with the DSi and BSi budgeting presented in the paper.

    Conclusions: The differences in consumption of drugs against osteoporosis in the Baltic countries are not very big. The consumption of antiosteoporotic drugs is not to be regarded as sufficient though. The generally low consumption of osteoporotic medicines in the Baltic countries can be attributed to the overall less than EU average wealth of the countries and less than optimal expenditure on healthcare out of the GDP.

    The Baltic Sea is a unique ecological system, an integral part of the global ecological system, which is in urgent need of protection from destructive anthropogenic impact stemming from the production and consumption of nuclear energy and artificial radionuclides, agriculture, oil and oil product transportation, and sewage and solid waste treatment. The article outlines the main environmental problems of the Baltic Seas and the ways to solve them.

    A radiological assessment has been carried out considering discharges of radioactivity to the Baltic Sea marine environment since 1950. The sources of radioactivity that have been evaluated are atmospheric nuclear-weapons fallout, fallout from the Chernobyl accident in 1986, discharges of radionuclides from Sellafield and La Hague transported into the Baltic Sea, and discharges of radionuclides from nuclear installations located in the Baltic Sea area. Dose rates from man-made radioactivity to individual members of the public (critical groups) have been calculated based on annual intake of seafood and beach occupancy time. The dose rates to individuals from the regions of the Bothnian Sea and Gulf of Finland are predicted to be larger than from any other area in the Baltic Sea due to the pattern of Chernobyl fallout. The dose rates are predicted to have peaked in 1986 at a value of 0.2 mSv year-1. Collective committed doses to members of the public have been calculated based on fishery statistics and predicted concentrations of radionuclides in biota and coastal sediments. The total collective dose from man-made radioactivity in the Baltic Sea is estimated at 2600 manSv, of which approximately two-thirds originate from Chernobyl fallout, approximately one-quarter from atmospheric nuclear-weapons fallout, approximately 8% from European reprocessing facilities, and approximately 0.04% from nuclear installations bordering the Baltic Sea area. An assessment of small-scale dumping of low-level radioactive waste in the Baltic Sea in the 1960s by Sweden and the Soviet Union has showed that doses to man from these activities are negligible. Dose rates and doses from natural radioactivity dominate except for the year 1986 where dose rates to individuals from Chernobyl fallout in some regions of the Baltic Sea approached those from natural radioactivity.

    Anthropogenically induced changes in precipitation are projected to generate increased river runoff to semi-enclosed seas, intensifying loads of terrestrial dissolved organic matter and decreasing salinity. To determine how bacterial community structure and functioning adjust to such changes, we designed microcosm transplant experiments with Baltic Proper (salinity 7.2) and Bothnian Sea (salinity 3.6) water. Baltic Proper bacteria generally reached higher abundance than Bothnian Sea bacteria ...

  1. Insurance cost of Swedish nuclear power plants

    1992-01-01

    What happens if a reactor accident occurs? Can victims of a nuclear accident be compensated for losses? The rights of a victim of a nuclear accident to be compensated for losses are governed by international conventions. These conventions make the licensee of a nuclear plant strictly liable. However, the maximum amount of compensation is limited. In Sweden the total liability of the plant-owner is maximized to 1.2 million Swedish Crowns, that is 0.02 oere/kWh. After the accidents of Harrisburg (1979) and Chernobyl (1986), it has become clear that the amounts of the various conventions are not at all sufficient to cover the damages caused by such an accident. In spite of these facts, there are a large number of reliable sources, who think that the insurance costs are negligible in the cost of production. A cost-benefit analysis based on a study performed by Ottinger et al. in 'Environmental costs of electricity' is therefore adopted to derive the costs of the external effects of nuclear plant operation and from releases to the environment during operation. The environmental externality costs of Swedish nuclear power plant operations are in this report estimated to 18.3 oere/kWh. This figure can be compared to the insurance cost, which for the present is 0.02 oere/kWh. The 'real' insurance cost including the external effects is calculated to approximately 1.12 billion Swedish Crowns] That is 900 times larger than the insurance premium, which the licensee of a nuclear plant faces] (au)

  2. Operating experience from Swedish nuclear power plants

    The total production of electricity from Swedish nuclear power plants was 70.5 TWh during 1998, which is the second highest yearly production ever. Production losses due to low demand totaled 5.1 TWh combined for all twelve units and production losses due to coastdown operation totaled an additional 0.5 TWh. The reason for this low power demand was a very good supply of water to the hydropower system. Hydroelectric power production was 73.6 TWh, an increase by roughly 5 TWh since 1997. Hence, the hydroelectric power production substantially exceeded the 64 TWh expected during a normal year, i.e. a year with average rainfall. Remaining production sources, mainly fossil fuel electricity production combined with district heating, contributed with 10 TWh. The total electricity production was 154.2 TWh, the highest yearly production ever. The total electricity consumption including transmission losses was 143.5 TWh. This is also the highest consumption ever and an increase by one percent compared to 1997. The preliminary net result of the electric power trade shows a net export by 10.7 TWh. The figures above are calculated from the preliminary production results. A comprehensive report on electric power supply and consumption in Sweden is given in the 1998 Annual Report from the Swedish Power Association. Besides Oskarshamn 1, all plants have periodically been operated in load-following mode, mostly because of the abundant supply of hydropower. The energy availability for the three boiling water reactors at Forsmark averaged 93.3 % and for the three pressure water reactors at Ringhals 91.0 %, both figures are the highest ever noted. In the section `Special Reports` three events of importance to safety that occurred during 1998 are reported. The events were all rated as level 1 according to the International Nuclear Event Scale (INES) Figs, tabs.; Also available in Swedish

  3. Movements and instability in the Swedish bedrock

    The report gives a geological evaluation of the Swedish bedrock and its movements during the last 20,000 years, which may serve as a base for further evaluations of the possibilities of storing nuclear waste in the bedrock. The Swedish bedrock is by no means stable. Like all other bedrocks it is unstable. The Swedish bedrock has an old and rich tectono-geodynamic inheritance. Irregularities in the uplift in the form of shoreline bends and isobase irregularities have been established with ancient shorelines and geodetic data. They are in general all related to major faultlines and bedrock seams. Bouldery end moraines and bouldery ground in general register paleopseismic activity -(these areas must hence be excluded as alternatives for storage of nuclear waste in the bedrock). The next ice age, is either on its way or it will, under the most favorable circumstances, have begun 20,000years from now (AP). At the next ice age, all the seismic and neotectonic effects from the deglaciation period will be repeated. During an ice age. Nuclear waste cannot bestored in the bedrock. If one succed in finding a Precambrain bedrock unit within an area of smooth uplift, absence of recent earthquakes, the bedrock surface of which shows few fractures and no faultlines, and where the surroundings exhibit normal moraine features and normal till composition, this area must still be evaluated with respect to that which will happen and may happen in connection with the next ice age and in connection with the cyclic gravitational changes in the present linear uplift.

  4. Andrew spares Florida Coast

    When geologists heard of the intensity of Hurricane Andrew, which struck the Florida coast on August 25 and then moved on to southern Louisiana, they were expecting the same kinds of coastal damage that Hurricane Hugo brought to the Caribbean and Carolina shores in 1989. Both storms were category 4 hurricanes, having winds of 131-155 mph and surges of 13-18 feet. However, the coastal damage never materialized, leaving geologists to analyze the factors that lessened the impact of the storm. “For minimum coastal damage, you couldn't have designed a better storm,” said Orrin Pilkey, director of the Program for the Study of Developed Shorelines (PSDS) in Durham, N.C. This was due in part to the nature of the storm itself and where it hit land, and in part to the regional geology, said Rob Thieler of PSDS. Despite the huge amounts of damage to buildings, there was virtually no evidence of coastal process destruction, he said.

    The history of renal replacement therapy (RRT) in the 3 Baltic countries can be divided into 2 periods: the Soviet period (1944-1991) with strict central regulation and isolation from Western countries, and the period of independence (1991 to the present). Between 1963 and 1967, hemodialysis was used in cases of acute kidney injury and later in chronic renal failure, but only for patients suitable for kidney transplantation. The first renal transplant was performed in 1968, in Tartu, Estonia, and shortly thereafter, in Lithuania and Latvia. During the period of independence, development of RRT has been extremely rapid, and now this field of the health system has no major differences from that in other developed countries.

    This article examines two medieval chronicles dealing with the crusades in the Baltic. The Chronicon Livoniae by Henry, a German priest — and interpreter — in the region, provides an account of the crusades in Livonia and Estonia from c.1184 to c.1227. Henry was an eyewitness, even if surely biased...... chronicle examined in this article is the Chronicon terre Prussie. This chronicle, authored by a Teutonic Knight named Peter of Dusburg and written c.1326, relates the arrival and history of the Teutonic Order in Prussia from c.1230, also covering the initial submission of the Prussian pagans to Christian......, creating a struggle for autonomy and dominance. The two chronicles made considerable use of Scripture, albeit in different ways. This article investigates the uses of the Bible in both chronicles with a special eye to how ideas of providential history — that is the role assigned by the authors...

  15. Microplastics in Baltic bottom sediments: Quantification procedures and first results.

    Microplastics in the marine environment are known as a global ecological problem but there are still no standardized analysis procedures for their quantification. The first breakthrough in this direction was the NOAA Laboratory Methods for quantifying synthetic particles in water and sediments, but fibers numbers have been found to be underestimated with this approach. We propose modifications for these methods that will allow us to analyze microplastics in bottom sediments, including small fibers. Addition of an internal standard to sediment samples and occasional empty runs are advised for analysis quality control. The microplastics extraction efficiency using the proposed modifications is 92±7%. Distribution of microplastics in bottom sediments of the Russian part of the Baltic Sea is presented. Microplastic particles were found in all of the samples with an average concentration of 34±10 items/kg DW and have the same order of magnitude as neighbor studies reported.

    Good decision making for fisheries and marine ecosystems requires a capacity to anticipate the consequences of management under different scenarios of climate change. The necessary ecological forecasting calls for ecosystem-based models capable of integrating multiple drivers across trophic levels...... and properly including uncertainty. The methodology presented here assesses the combined impacts of climate and fishing on marine food-web dynamics and provides estimates of the confidence envelope of the forecasts. It is applied to cod (Gadus morhua) in the Baltic Sea, which is vulnerable to climate......-related decline in salinity owing to both direct and indirect effects (i.e. through species interactions) on early-life survival. A stochastic food web-model driven by regional climate scenarios is used to produce quantitative forecasts of cod dynamics in the twenty-first century. The forecasts show how...

    2017-11-01

    Full Text Available The family Cantharidae is a worldwide distributed group of flattened and soft-bodied beetles displaying aposematic colouration. These beetles, commonly known as soldier beetles, have an extensive fossil record dating back to the Lower Cretaceous. The majority of fossil material, referred to Cantharidae, is known from amber inclusions. In this paper we describe and illustrate a new soldier beetle Kuskaella macroptera gen. et sp. nov. from the Baltic amber. It is characterised by pronotum of the male parallel-sided in basal third and abruptly narrowed towards apex, and of the female gradually and steadily narrowing from the basal margin to the apex; globular head; unequal maxillary palpomeres with the last segment elongated-globular and pointed; long elytra slightly surpassing the last abdominal segment. This finding is the first described species of both sexes preserved in a single amber piece.
