    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

    2011-03-01

    The Keivy Terrane in the northeastern Baltic Shield appreciably differs from the adjacent tectonic blocks. In the northwestern part of this terrane (the Serpovidny Range), an outlier of Paleoproterozoic supracrustal rocks called the Serpovidny structure is surrounded by Archean (?) Keivy high-alumina paraschists. As follows from structural and magnetic data, the Paleoproterozoic rocks are deformed into a tight sheath fold 8 × 2 km in size at the surface and 5 km in length along the sheath axis. Faults parallel to the boundaries of the layers and locally cutting them off at an acute angle are involved in folding as well. The outer boundaries of the Serpovidny structure are tectonic. This structure is complementary to a larger tectonic lens composed of the Keivy mica schists. It is concluded that all of the supracrustal rocks of the Serpovidny Range are in fact tectonic sheets and lenses deformed into sheath folds. The literature data show that kilometer-scale sheath folds occur throughout the Keivy paraschist belt and most likely were formed owing to thrusting of the Murmansk Craton onto the Keivy Terrane in the south-southwestern direction. Foliation and lineation related to thrusting have been established in the Archean silicic metavolcanics and peralkaline granites occupying the most part of the terrane. In contrast, the granitoids and gabbroanorthosites of the Archean basement, which form a block 90 × 20 km in the southwestern Keivy Terrane, were not affected by Paleoproterozoic deformation. In other words, a detached assembly of tectonic sheets composed of the upper and middle crustal rocks that underwent deformation at the initial stage of the Paleoproterozoic Lapland-Kola Orogeny and the Archean basement, which is free of this deformation, are distinguished. The depth of detachment is estimated at 20-25 km. The detachment of the upper and middle crust in the Keivy Terrane and its position in the structure of the Baltic Shield are consistent with a

    2000-06-01

    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.

    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.

  19. Uncertainty management in stratigraphic well correlation and stratigraphic architectures: A training-based method

    Science.gov (United States)

    Edwards, Jonathan; Lallier, Florent; Caumon, Guillaume; Carpentier, Cédric

    2018-02-01

    We discuss the sampling and the volumetric impact of stratigraphic correlation uncertainties in basins and reservoirs. From an input set of wells, we evaluate the probability for two stratigraphic units to be associated using an analog stratigraphic model. In the presence of multiple wells, this method sequentially updates a stratigraphic column defining the stratigraphic layering for each possible set of realizations. The resulting correlations are then used to create stratigraphic grids in three dimensions. We apply this method on a set of synthetic wells sampling a forward stratigraphic model built with Dionisos. To perform cross-validation of the method, we introduce a distance comparing the relative geological time of two models for each geographic position, and we compare the models in terms of volumes. Results show the ability of the method to automatically generate stratigraphic correlation scenarios, and also highlight some challenges when sampling stratigraphic uncertainties from multiple wells.

  20. Stratigraphic implications of uranium deposits

    International Nuclear Information System (INIS)

    Langford, F.F.

    1980-01-01

    One of the most consistent characteristics of economic uranium deposits is their restricted stratigraphic distribution. Uraninite deposited with direct igneous affiliation contains thorium, whereas chemical precipitates in sedimentary rocks are characterized by thorium-free primary uranium minerals with vanadium and selenium. In marine sediments, these minerals form low-grade disseminations; but in terrestrial sediments, chiefly fluvial sandstones, the concentration of uranium varies widely, with the high-grade portions constituting ore. Pitchblende vein deposits not only exhibit the same chemical characteristics as the Colorado-type sandstone deposits, but they have a stratigraphically consistent position at unconformities covered by fluvial sandstones. If deposits in such diverse situations have critical features in common, they are likely to have had many features of their origin in common. Thus, vein deposits in Saskatchewan and Australia may have analogues in areas that contain Colorado-type sandstone deposits. In New Mexico, the presence of continental sandstones with peneconformable uranium deposits should also indicate good prospecting ground for unconformity-type vein deposits. All unconformities within the periods of continental deposition ranging from Permian to Cretaceous should have uranium potential. Some situations, such as the onlap of the Abo Formation onto Precambrian basement in the Zuni Mountains, may be directly comparable to Saskatchewan deposition. However, uranium occurrences in the upper part of the Entrada Sandstone suggest that unconformities underlain by sedimentary rocks may also be exploration targets

    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.

    Full Text Available Introduction    The Baltic Sea, an internal sea of the European Community, isone of the largest brackish water bodies in the world. It isquite unique in many respects, particularly in its natural featuresand in the cultural, political and socio-economic patterns ofthe countries bordering it.    After nearly 40 years, during which Baltic marine physicists,chemists, biologists and geologists had been holding separatescientific meetings, it was decided the time was ripe to arrangejoint scientific conferences with the purpose of getting togetherto discuss general and specific aspects of the Baltic Sea, toexchange information, to integrate efforts, and to get to knowand understand each other better. The Sopot 2005 Congress, precededby the Baltic Sea Science Congresses in Rønne (1997, Warnemünde(1999, Stockholm (2001 and Helsinki (2003, was the fifth jointmeeting of the Conference of Baltic Oceanographers (CBO, BalticMarine Biologists (BMB and Baltic Sea Geologists (BSG. Likeall the previous congresses, the one held in Sopot bore witnessto the idea that we all, members of CBO, BMB and BSG, shouldcontinue to work together even more closely.    The meeting in Sopot instigated discussion on a broad spectrumof problems, from large-scale climate change-related processesto local, small-scale specific Baltic Sea features. Further subjectsfor deliberation included modelling as a research tool and asa way of providing services and forecasting certain phenomena,operational oceanography, and man's impact on the Baltic Seaenvironment and its resources.    We are indebted to our Scientific Committee for their work duringthe past months to sort out and select interesting contributionsto all the oral and poster sessions, and thus for making theCongress an attractive and quality event. We also thank the PolishAcademy of Sciences and the City of Sopot for their financialsupport.    We hope that the joint Congress and fruitful scientific

  7. Some debatable problems of stratigraphic classification

    2014-05-01

    Russian geologists perform large-scale geological mapping in Russia and abroad. Therefore we urge unification of legends of geological maps compiled in different countries. It seems important to continuously organize discussions on problems of stratigraphic classification. 1. The stratigraphic schools (conventionally called "European" and "American") define "stratigraphy" in different ways. The former prefers "single" stratigraphy that uses data proved by many methods. The latter divides stratigraphy into several independent stratigraphers (litho-, bio-, magneto- and others). Russian geologists classify stratigraphic units into general (chronostratigraphic) and special (in accordance with a method applied). 2. There exist different interpretations of chronostratigraphy. Some stratigraphers suppose that a chronostratigraphic unit corresponds to rock strata formed during a certain time interval (it is somewhat formalistic because a length of interval is frequently unspecified). Russian specialists emphasize the historical-geological background of chronostratigraphic units. Every stratigraphic unit (global and regional) reflects a stage of geological evolution of biosphere and stratisphere. 3. In the view of Russian stratigraphers, the main stratigraphic units may have different extent: a) global (stage), b) regional (regional stage,local zone), and c) local (suite). There is no such hierarchy in the ISG. 4. Russian specialists think that local "lithostratigraphic" units (formations) which may have diachronous boundaries are not chronostratigraphic ones in strict sense (actually they are lithological bodies). In this case "lithostratigraphy" can be considered as "prostratigraphy" and employed in initial studies of sequences. Therefore, a suite is a main local unit of the Russian Code and differs from a formation, although it is somewhat similar. It does not mean that lithostratigraphy is unnecessary. Usage of marker horizons, members and other bodies is of great help

    In 2007 the Helcom (The Helsinki Comity), representing most of the countries around the Baltic, made an agreement for the future of the Baltic Sea, on reducing the nutrient input to the Baltic Sea and thereby avert further environmental damage, called the Baltic Sea Action Plan (BSAP). 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...

  12. Sustainable energy in Baltic States

    International Nuclear Information System (INIS)

    Klevas, Valentinas; Streimikiene, Dalia; Grikstaite, Ramute

    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

    2003-01-01

    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. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

  17. The petroleum system of the lower Palaeozoic strata in the central part of the Baltic basin

    2013-04-01

    The Baltic Basin is an intra-cratonic sedimentary basin with conspicuous Early Palaeozoic sections. In terms of hydrocarbon prospectively, the it has been perceived as a classical oil basin with several tens of relatively small oil and gas fields occur there over a wide stratigraphic interval, ranging from the crystalline basement through the entire Lower Palaeozoic succession. Until now conventional oil has been predominantly produced in the basin, i.e. only few conventional gas accumulations have been found in the Polish Baltic Sea offshore. Petroleum potential within the basin also is associated with Silurian reefogenic and carbonate build-ups. New organic geochemistry data as well revealed the potential for shale gas/oil in the basin. The analysis of the composition of the organic matter and crude oils from Kaliningrad region (Russia) and Lithuanian revealed genesis and the general trends of the migration of hydrocarbons in the Baltic Basin. The organic matter of the source rocks is of similar composition and represents typical marine type II, showing considerable variations of the maturity thought the basin: ranging from immature in the eastern Lithuania and Kaliningrad region of Russia to oil window to the south-west. In some places the anomalously high maturity of organic matter, indicating the lower part of the wet gas/condensate window have been recorded, most probably being related to the locally increased paleo-temperatures. Oils of the Baltic Basin have low densities (Oils of the Baltic Basin are not biodegraded, despite their early emplacement (e.g. by the Lower Palaeozoic age) and the relatively low present reservoir temperatures. Results of biomarker and stable carbon isotope analyses allow three genetic oil groups to be distinguished in the Kaliningrad region. These oils appear to be confined to tectonically distinct areas suggesting that the hydrocarbons were derived from different kitchens. The hydrocarbon generation in the Baltic Basin started by

  18. BALTIC CONTAINER SHIPPING MARKET GOES GLOBAL

    Directory of Open Access Journals (Sweden)

    Ernest Czermański

    2016-03-01

    Full Text Available This paper aims at summarizing the last period of the Baltic container shipping mar-ket’s development, especially after 2000. The author, taking especially into account changes that have occurred in 2010, ultimately demonstrate that through the analyzed changes, this market has become a global one - thus being shaped by global determinants influencing its further development. Author selected and analyzed some chosen, most important factors influencing future market development. Secondly, some chances and threats resulting from the described changes were presented, either for the entire market as a base for international trade of Baltic Sea Region countries, and for its actors, mainly shipping owners and operators acting as a supply side of the Baltic container market. Finally, author has tried to verify and questioned the doubts and strong concerns about the future of the Baltic container shipping, especially about the feeder services, as because there are real indications and arguments against these concern.

  19. Solar radiation in the Baltic Sea

    Directory of Open Access Journals (Sweden)

    Jerzy Dera

    2010-12-01

    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. This opportunity is presented by the

    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.

    BALTEX is an environmental research network dealing with the Earth system of the entire Baltic Sea drainage basin. Important elements include the water and energy cycle, climate variability and change, water management and extreme events, and related impacts on biogeochemical cycles. BALTEX was founded in 1993 as a GEWEX continental-scale experiment and is currently in its second 10 yr phase. Phase I (1993–2002) was primarily dedicated to hydrological, meteorological and oceanographic processes in the Baltic Sea drainage basin, hence mostly dealt with the physical aspects of the system. Scientific focus was on the hydrological cycle and the exchange of energy between the atmosphere, the Baltic Sea and the surface of its catchment. The BALTEX study area was hydrologically defined as the Baltic Sea drainage basin. The second 10 yr phase of BALTEX (Phase II: 2003–12) has strengthened regional climate research, water management issues, biogeochemical cycles and overarching efforts to reach out to stakeholders and decision makers, as well as to foster communication and education. Achievements of BALTEX Phase II have been the establishment of an assessment report of regional climate change and its impacts on the Baltic Sea basin (from hydrological to biological and socio-economic), the further development of regional physical climate models and the integration of biogeochemical and ecosystem models. BALTEX features a strong infrastructure, with an international secretariat and a publication series, and organizes various workshops and conferences. This article gives an overview of the BALTEX programme, with an emphasis on Phase II, with some examples from BALTEX-related research.

  5. Economics of Developing Hot Stratigraphic Reservoirs

    Energy Technology Data Exchange (ETDEWEB)

    Greg Mines; Hillary Hanson; Rick Allis; Joseph Moore

    2014-09-01

    Stratigraphic geothermal reservoirs at 3 – 4 km depth in high heat-flow basins are capable of sustaining 100 MW-scale power plants at about 10 c/kWh. This paper examines the impacts on the levelized cost of electricity (LCOE) of reservoir depth and temperature, reservoir productivity, and drillhole/casing options. For a reservoir at 3 km depth with a moderate productivity index by hydrothermal reservoir standards (about 50 L/s/MPa, 5.6 gpm/psi), an LCOE of 10c/kWh requires the reservoir to be at about 200°C. This is the upper temperature limit for pumps. The calculations assume standard hydrothermal drilling costs, with the production interval completed with a 7 inch liner in an 8.5 inch hole. If a reservoir at 4 km depth has excellent permeability characteristics with a productivity index of 100 L/s/MPa (11.3 gpm/psi), then the LCOE is about 11 c/kWh assuming the temperature decline rate with development is not excessive (< 1%/y, with first thermal breakthrough delayed by about 10 years). Completing wells with modest horizontal legs (e.g. several hundred meters) may be important for improving well productivity because of the naturally high, sub-horizontal permeability in this type of reservoir. Reducing the injector/producer well ratio may also be cost-effective if the injectors are drilled as larger holes.

  6. From Baltic rooms to conference rooms: my jouney with data

    From time spent in murky, mosquito-filled mangrove swamps searching for fiddler crabs, to being transported off ships in webbed "man-baskets" on inky-black winter mornings to sample sea ice, to teaching rooms full of students the benefits of information organization, the wonders of science have long shaped my career path. Regardless of surroundings, the driving factor has always been a desire to learn new skills, then try to figure out how to use them to make work easier or more efficient for myself and hopefully others. Somewhere along the way, I've switched from doing it primarily for my "own" research projects, to a focus on helping others with theirs. Like many in this field, my route to a career in data science has influenced how I do my work. Along the way I've carried skills with me but also learned a few things that have made my journey both practical and fun. In this presentation, I'll discuss a few key factors that contribute to my current efforts as a data curation specialist in a research library, including communication (translation of "library" concepts to "science" concepts and vice versa), flexibility (ability to accomodate ideas, pace and values of those I'm working with), and prioritization (learning to balance what's valuable to researchers with principles important to libraries, curators, repositories, archives and other groups with which I interact).

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

    Science.gov (United States)

    Neumann, Thomas; Radtke, Hagen; Seifert, Torsten

    2017-02-01

    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.

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

    Sopher, Daniel; Erlström, Mikael; Bell, Nicholas; Juhlin, Christopher

    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.

    The mean annual growth rate of grey seal stock in the Baltic has been on average 7.5% annually during the last decade. In 2010, a total of approximately 23 100 grey seals were counted. The increase in stock size was highest in the northern areas and the predation pressure of grey seals on clupeoids...... has increased accordingly. The diet of grey seal in the Baltic consists of ca. 20 fish species. The most abundant prey items in the Baltic proper are Baltic herring, sprat, and cod, and in the Bothnian Sea and Bothnian Bay Baltic herring, Coregonus sp., Baltic salmon, and sea trout. An adult seal...... consumes on average round 4.5 kg fish per day, of which 55% are clupeoids in the Baltic Main basin and 70% in the Bothnian Sea and Bothnian Bay.

  12. The stratigraphic filter and bias in measurement of geologic rates

    Science.gov (United States)

    Schumer, Rina; Jerolmack, Douglas; McElroy, Brandon

    2011-01-01

    Erosion and deposition rates estimated from the stratigraphic record frequently exhibit a power-law dependence on measurement interval. This dependence can result from a power-law distribution of stratigraphic hiatuses. By representing the stratigraphic filter as a stochastic process called a reverse ascending ladder, we describe a likely origin of power-law hiatuses, and thus, rate scaling. While power-law hiatuses in certain environments can be a direct result of power-law periods of stasis (no deposition or erosion), they are more generally the result of randomness in surface fluctuations irrespective of mean subsidence or uplift. Autocorrelation in fluctuations can make hiatuses more or less heavy-tailed, but still exhibit power-law characteristics. In addition we show that by passing stratigraphic data backward through the filter, certain statistics of surface kinematics from their formative environments can be inferred.

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

    Science.gov (United States)

    McCrackin, M. L.

    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.

    2004-06-01

    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.

    Birk Mortensen, J.

    1994-03-01

    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)

    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.

    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.

  15. Measuring Stratigraphic Congruence Across Trees, Higher Taxa, and Time.

    The congruence between the order of cladistic branching and the first appearance dates of fossil lineages can be quantified using a variety of indices. Good matching is a prerequisite for the accurate time calibration of trees, while the distribution of congruence indices across large samples of cladograms has underpinned claims about temporal and taxonomic patterns of completeness in the fossil record. The most widely used stratigraphic congruence indices are the stratigraphic consistency index (SCI), the modified Manhattan stratigraphic measure (MSM*), and the gap excess ratio (GER) (plus its derivatives; the topological GER and the modified GER). Many factors are believed to variously bias these indices, with several empirical and simulation studies addressing some subset of the putative interactions. This study combines both approaches to quantify the effects (on all five indices) of eight variables reasoned to constrain the distribution of possible values (the number of taxa, tree balance, tree resolution, range of first occurrence (FO) dates, center of gravity of FO dates, the variability of FO dates, percentage of extant taxa, and percentage of taxa with no fossil record). Our empirical data set comprised 647 published animal and plant cladograms spanning the entire Phanerozoic, and for these data we also modeled the effects of mean age of FOs (as a proxy for clade age), the taxonomic rank of the clade, and the higher taxonomic group to which it belonged. The center of gravity of FO dates had not been investigated hitherto, and this was found to correlate most strongly with some measures of stratigraphic congruence in our empirical study (top-heavy clades had better congruence). The modified GER was the index least susceptible to bias. We found significant differences across higher taxa for all indices; arthropods had lower congruence and tetrapods higher congruence. Stratigraphic congruence-however measured-also varied throughout the Phanerozoic, reflecting

    Bottom sediments play an important role in radioecological studies of the marine environment because a large proportion of radioactive substances entering the sea is adsorbed over time onto suspended particulate matter and deposited in sediments. Generally, this is the final sink for most of the organic material produced in the water phase, as well as for other particles transported by water currents from other sea areas and from adjacent terrestrial areas. During their slow settling, the particles tend to bind radionuclides from the water phase and carry them to the bottom. Under favourable conditions, the deposited particles form undisturbed laminae in a stratigraphic sequence on the seabed, and the bottom sediments create an archive from which the history of the area can be read. Various particle-bound substances can be identified as markers of specific historical events and, with the aid of marker horizons, the laminae can be dated. Modern dating methods provide reliable time scales in which time-dependent changes in the concentrations of radionuclides can be recorded. As an example, the radioactive fallout from atmospheric nuclear weapons tests in the 1950s and 1960s and the accident at the Chernobyl Nuclear Power Plant in April 1986 have created useful markers in the sediments of many sea areas, especially in the Baltic Sea. The Baltic Sea offers exceptionally good opportunities to conduct sedimentological studies because the average rate of sedimentation there is much higher than in the oceans and in most other coastal seas. The anoxic conditions in the near-bottom water of the Baltic Proper, and hence the lack of benthic animals over large bottom areas, result in the formation of an undisturbed sedimentary medium, which enables the sampling of sediment laminae in an undisturbed stratigraphic sequence. However, sediment sampling is extremely sensitive to errors, which can cause substantial differences in results. This fact should always be taken into account

  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

    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)

    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.

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.

    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.

    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.

    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

  4. 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.

  5. Tectonic regimes in the Baltic Shield during the last 1200 Ma - A review

    Larsson, S.Aa.; Tullborg, E.L. and

    1993-11-01

    This report is a review about tectonic regimes in the Baltic (Fennoscandian) Shield from the Sveconorwegian (1.2 Ga ago) to the present. It also covers what is known about palaeostress during this period, which was chosen to include both orogenic and anorogenic events. A summery is given in table form, and a litho-stratigraphic map of Baltica including adjacent sea areas is enclosed. Plate movements are the ultimate reason for stress build-up in the crust. It is concluded that continental drift and rotation velocity have changed during the Earth's history. Periods of convergence and collision between continents are succeeded by periods of continental break-up. The different stress regimes, which prevailed during fracturing, produced specific fracture patterns on different scales. These fractures were reactivated during later favourable stress regimes. Within the next 100 000 years the stress situation of the Baltica crust will not change, except for the effects imposed by the growth and melting of an ice cover. 214 refs

Overall, FDI has contributed to economic growth in the Baltic economies, having financed around one-fifth of fixed investment. However, their small size makes the Baltic countries relatively less attractive for market-seeking FDI in manufacturing. Moreover, at the outset of transition, their ...

    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.

  10. 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.

  11. 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.

  12. Determination of Heat Capacity of Yucca Mountain Stratigraphic Layers

    2006-01-01

    The heat generated from the radioactive waste to be placed in the proposed geologic repository at Yucca Mountain, Nevada, will affect the thermal-hydrology of the Yucca Mountain stratigraphic layers. In order to assess the effect of the movement of repository heat into the fractured rocks accurate determination of thermodynamic and hydraulic properties is important. Heat capacity is one of the properties that are required to evaluate energy storage in the fractured rock. Rock-grain heat capacity, the subject of this study, is the heat capacity of the solid part of the rock. Yucca Mountain consists of alternating lithostratigraphic units of welded and non-welded ash-flow tuff, mainly rhyolitic in composition and displaying varying degrees of vitrification and alteration. A number of methods exist that can be used to evaluate heat capacity of the stratigraphic layers that consist of different compositions. In this study, the mineral summation method has been used to quantify the heat capacity of the stratigraphic layers based on Kopp's rule. The mineral summation method is an addition of the weighted heat capacity of each mineral found in a specific layer. For this study the weighting was done based on the mass percentage of each mineral in the layer. The method utilized a mineralogic map of the rocks at the Yucca Mountain repository site. The Calico Hills formation and adjacent bedded tuff layers display a bimodal mineral distribution of vitric and zeolitic zones with differing mineralogies. Based on this bimodal distribution in zeolite abundance, the boundary between the vitric and zeolitic zones was selected to be 15% zeolitic abundance. Thus, based on the zeolite abundance, subdivisions have been introduced to these layers into ''vitric'' and ''zeolitic'' zones. Heat capacity values have been calculated for these layers both as ''layer average'' and ''zone average''. The heat capacity determination method presented in this report did not account for spatial

  13. Fossil preservation and the stratigraphic ranges of taxa

    Science.gov (United States)

    Foote, M.; Raup, D. M.

    1996-01-01

    The incompleteness of the fossil record hinders the inference of evolutionary rates and patterns. Here, we derive relationships among true taxonomic durations, preservation probability, and observed taxonomic ranges. We use these relationships to estimate original distributions of taxonomic durations, preservation probability, and completeness (proportion of taxa preserved), given only the observed ranges. No data on occurrences within the ranges of taxa are required. When preservation is random and the original distribution of durations is exponential, the inference of durations, preservability, and completeness is exact. However, reasonable approximations are possible given non-exponential duration distributions and temporal and taxonomic variation in preservability. Thus, the approaches we describe have great potential in studies of taphonomy, evolutionary rates and patterns, and genealogy. Analyses of Upper Cambrian-Lower Ordovician trilobite species, Paleozoic crinoid genera, Jurassic bivalve species, and Cenozoic mammal species yield the following results: (1) The preservation probability inferred from stratigraphic ranges alone agrees with that inferred from the analysis of stratigraphic gaps when data on the latter are available. (2) Whereas median durations based on simple tabulations of observed ranges are biased by stratigraphic resolution, our estimates of median duration, extinction rate, and completeness are not biased.(3) The shorter geologic ranges of mammalian species relative to those of bivalves cannot be attributed to a difference in preservation potential. However, we cannot rule out the contribution of taxonomic practice to this difference. (4) In the groups studied, completeness (proportion of species [trilobites, bivalves, mammals] or genera [crinoids] preserved) ranges from 60% to 90%. The higher estimates of completeness at smaller geographic scales support previous suggestions that the incompleteness of the fossil record reflects loss of

  14. 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

  16. Metal pollutants and radionuclides in the Baltic Sea - an overview

    Directory of Open Access Journals (Sweden)

    Piotr Szefer

    2002-06-01

    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

    Green, A. N.; Cooper, J. A. G.

    2018-02-01

    This special issue of Geo-Marine Letters comprises seven contributions to the session "Stratigraphic and morphologic signatures of continental shelves" of the 35th International Geological Congress held in Cape Town (Republic of South Africa) on 27 August-4 September 2016. There is an additional article not presented at the conference but falling into the same general theme. The guest editors are A.N. Green and J.A.G. Cooper. The eight articles address several contemporary themes in continental shelf geology. They include the role of antecedent conditioning on the development of shelf stratigraphy and geomorphology; erosion of submerged shorelines and their preservation during (stepped) postglacial sea-level rise; the role of glacial processes (e.g. iceberg scouring during ice-sheet retreat); and the utility of archival data in addressing contemporary issues such as Holocene climate change and global oceanographic circulation systems. The continental shelf holds important information for understanding past and present global circulation and earth-ice-atmosphere interactions including sea-level change. It is hoped that these themes will spur further research that is slowly coming to the fore in several new and innovative mapping and exploration programmes emerging from an increasing number of coastal nations.

    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.

    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

    The prehistory of the Baltic Sea has for a long time suffered from imprecise dating, due to the large uncertainties associated with bulk radiocarbon dating of Baltic Seasediments. To constrain the timing of environmental changes in the Baltic Sea it is critical to apply new dating approaches. This

  12. Accommodation and supply—a dual control on stratigraphic sequences

    Schlager, Wolfgang

    1993-07-01

    It is widely accepted that both eustatic and tectonically controlled regional changes of sea level have contributed to the record of stratigraphic sequences. I suggest that environmental change be added as a third, autonomous control. Sedimentologic principles clearly indicate that sequences and their systems tracts are controlled by the interplay of two rates —the rate of change in accommodation (space available for sedimentation) and the rate of sediment supply. Sea level has direct control on accommodation, but its influence on sediment supply is remote and easily overshadowed by environmental factors. For instance, the record of the most recent sea-level rise is a transgressive systems tract where supply is low; it is a prograding highstand systems tract in deltas where the supply is high. Examples of sequence boundaries generated by changes in sediment supply include tectonically driven shifts in sediment input into basins, changes in ocean currents, pulsating supply from failure of submarine slopes and drowning of carbonate platforms by environmental stress. Furthermore, the stratigraphic sequences in fluviatile continental basins are physically removed from sea-level induced changes in accommodation and must have formed by changes in the rate and pattern of supply. Subaerial exposure of marine sediments at the sequence boundary is a most important criterion for recognizing sea level cycles as opposed to supply cycles. Other criteria include downstepping of shelf breaks and characteristic patterns in the spacing of time lines within sequences. Some third-order cycles (ca. 0.5-3 Ma duration) meet these criteria, others do not. Cycle-stacking patterns and the shifting facies belts on cratons indicate that many second- and third-order cycles lack pronounced exposure unconformities and represent gradual changes superimposed on more rapid, shorter oscillations. Seismic data yield poor images of these gradational changes because they lack resolution. Seismic

  13. Venusian extended ejecta deposits as time-stratigraphic markers

    Izenberg, Noam R.

    1992-01-01

    Use of impact crater ejects at time-stratigraphic markers was established during lunar geologic mapping efforts. The basic premise is that the deposition of impact ejecta, either by itself or mixed with impact-excavated material, is superimposed on a surface. The deposit becomes an observable, mappable unit produced in a single instant in geologic time. Up to two-thirds of Venus craters exhibit extended ejecta deposits. A reconnaissance survey of 336 craters (about 40 percent of the total population) was conducted. About half the craters examined were located in and around the Beta-Atla-Themis region, and half were spread over the western hemisphere of the planet. The survey was conducted using primarily C1-MIDR images. The preliminary survey shows: (1) of the 336 craters, 223 were found to have extended ejecta deposits. This proportion is higher than that found in other Venus crater databases by up to a factor of 2. (2) 53 percent of all extended ejecta craters were unambiguously superimposed on all volcanic and tectonic units. Crater Annia Faustina's associated parabolic ejecta deposit is clearly superimposed on volcanic flows coming from Gula Mons to the west. Parabola material from Faustina has covered the lava flows, smoothing the surface and reducing its specific backscatter cross section. The stratigraphy implies that the parabola material is the youngest observable unit in the region. (3) 12 percent of extended ejecta deposits are superimposed by volcanic materials. Crater Hwangcini has extended ejecta that has been covered by volcanic flows from a dome field to the northwest, implying that the volcanic units were emplaced subsequent to the ejecta deposit and are the youngest units in the locality. (4) It is difficult to determine the stratigraphic relationships of the remaining extended ejecta deposits in SAR at C1-MIDR resolution. Examination of higher resolution images and application of the other Magellan datasets in systematic manner should resolve

  14. OWL representation of the geologic timescale implementing stratigraphic best practice

    2011-12-01

    The geologic timescale is a cornerstone of the earth sciences. Versions are available from many sources, with the following being of particular interest: (i) The official International Stratigraphic Chart (ISC) is maintained by the International Commission for Stratigraphy (ICS), following principles developed over the last 40 years. ICS provides the data underlying the chart as part of a specialized software package, and the chart itself as a PDF using the standard colours; (ii) ITC Enschede has developed a representation of the timescale as a thesaurus in SKOS, used in a Web Map Service delivery system; (iii) JPL's SWEET ontology includes a geologic timescale. This takes full advantage of the capabilities of OWL. However, each of these has limitations - The ISC falls down because of incompatibility with web technologies; - While SKOS supports multilingual labelling, SKOS does not adequately support timescale semantics, in particular since it does not include ordering relationships; - The SWEET version (as of version 2) is not fully aligned to the model used by ICS, in particular not recognizing the role of the Global Boundary Stratotype Sections and Point (GSSP). Furthermore, it is distributed as static documents, rather than through a dynamic API using SPARQL. The representation presented in this paper overcomes all of these limitations as follows: - the timescale model is formulated as an OWL ontology - the ontology is directly derived from the UML representation of the ICS best practice proposed by Cox & Richard [2005], and subsequently included as the Geologic Timescale package in GeoSciML (http://www.geosciml.org); this includes links to GSSPs as per the ICS process - key properties in the ontology are also asserted to be subProperties of SKOS properties (topConcept and broader/narrower relations) in order to support SKOS-based queries; SKOS labelling is used to support multi-lingual naming and synonyms - the International Stratigraphic Chart is implemented

    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

    The research station at Studsvik is situated on the Baltic coast and includes several reactors and laboratories, a waste disposal plant serving both the station and waste producers outside Studsvik. A storage plant for irradiated fuel from power reactors has also been built. A total of 850 people are employed. The waste disposal plant was designed for a personnel of 900 using foreign information to correlate waste amounts to personnel. After a delay production has increased at a rate very close to the one expected. The composition of the waste is varied and difficult to predict. Minor amounts of fission products, active corrosion products, and fissile materials have been detected. Most of the waste activity is released to a strait leading into the Bay. Large volumes of water with very low specific activity are released immediately off the coast. Hydrological and dispersion data for the bay are quoted from a paper presented at the symposium mentioned below. The Baltic has brackish water. Both the chemistry and the biology are quite different from those of marine or fresh water recipients. A short description is given of the fauna and flora and important food webs are discussed. The different ways in which man is exposed to radioactivity in waste releases are dependent upon biological accumulation in living organisms and adsorption to dead materials. Fish consumption is the type of exposure which is likely to be the most critical, though it is possible that the exposure from sunbathing and fishing-gear handling could reach similar significance if conservative calculations are used. Accumulation factors from water to fish are given for iron, cobalt,and zinc . Permissible releases have been calculated using relevant accumulation factors. Fission products and corrosion products seem to be of similar significance with regard to possible human exposure.

    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.

    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.

    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.)

    Drilling practice at the field has been modified in several ways as better information is being obtained. The stratigraphic sequence of the area is made up of three sedimentary rock units of deltaic origin having different densities. These units have been named non-consolidated, semi-consolidated, and consolidated rocks; the thermal reservoirs are located in the latter. To investigate how the drilling rates are affected by the three rock units, plots of drilling advance versus time were made for a large number of wells. A typical plot is shown and drilling rates are practically constant in three different zones; that is, the drilling rate has only two breaks or changes in slope.

    2012-12-01

    Thousands and even millions of years from now, widespread anthropogenic contaminants in sediments would likely persist, incorporated into the geological record. They would inadvertently preserve evidence of our present era (informally designated as the Anthropocene Epoch) characterized by large human populations engaged in intensive industrial and agricultural activities. Hypothetical geologists in the distant future would likely find unusually high concentrations of a wide variety of contaminants at stratigraphic levels corresponding to our present time, analogous to the iridium anomaly marking the bolide impact event at the close of the Cretaceous Period. These would include both organic and inorganic substances, such as industrially-derived heavy metals (e.g., Hg, Pb, Cr, Zn) and hydrocarbons, both petrogenic (derived directly from petroleum) and pyrogenic (combustion products). While there are natural sources for these materials, such as volcanic eruptions, wildfires, and oil seeps, their co-occurrence would provide a signature characteristic of human activity. Diagnostic assemblages of organic compounds would carry an anthropogenic imprint. The distribution of polycyclic aromatic hydrocarbons (PAHs) in a sediment sample could distinguish between natural and human sources. Stable isotopic signatures would provide additional evidence. Concentrations of contaminants in the sedimentary record would increase exponentially with increasing proximity to urban source areas, where at present billions of people are collectively consuming vast quantities of fossil fuels and generating large amounts of waste. Aolian and marine transport prior to deposition has been seen at present to globally redistribute detectable amounts of contaminants including Hg and PAHs, even at great distances from principal source areas. For organic contaminants, deposition in an anoxic sedimentary environment could insure their preservation, increasing the likelihood of their inclusion in the

    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.

    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)

    Removal of fixed nitrogen in the water column of the eastern Gotland Basin, central Baltic Sea, was studied during two cruises in September 2008 and August 2010. The water column was stratified with anoxic sulfidic bottom water meeting oxic nitrate containing water at the oxic–anoxic interface......3 or sulfide concentrations were converted to in situ rates using the measured water column concentrations of NO3 and sulfide and the actual measured relations between NO3 and sulfide concentrations and enitrification rates. In situ denitrification ranged from 0.24 to 15.9 nM N2 h1. Assuming...... area. Even with an active denitrification layer of 3–6 m thickness the pelagic denitrification per unit area clearly exceeded sediment denitrification rates elsewhere in the Baltic Sea. When extrapolated to the entire Baltic Proper (BP) denitrification in the water column was in the range of 132...

    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)

    Martin Lodenius

    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.

  17. Understanding the ecocline at shallow coasts 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.

  18. 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.

  19. 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

    2012-05-01

    Full Text Available The brachiopod Hirnantia sagittifera (M’Coy and trilobite morphs of the genus Mucronaspis from the topmost Ordovician Porkuni Stage of the central East Baltic are described and compared with those from the Hirnantian Stage of other regions. These important Hirnantian taxa occur in the Livonian Tongue of the Central Baltoscandian Facies Belt of the Baltic Basin, where the Porkuni Stage is represented by the non-graptolitic Kuldiga and Saldus formations. Hirnantia sagittifera appears in the lowermost part of the Porkuni Stage and is rather widely distributed in the basin in spite of its rare finds in each locality. Our study of trilobites of the genus Mucronaspis has enabled us to observe morphological changes in its exoskeleton in time and to identify a succession of five morphotypes (morphs. In some characteristics these morphs are similar to those of different alleged species of the genus Mucronaspis (M. olini, M. danai, M. ganabina, M. mucronata but they cannot be definitely assigned to any of these species due to some variances. However, here for the first time a stratigraphically ordered collection is presented, which deserves attention in revising the taxonomy of highly variable Mucronaspis. The described brachiopods and trilobites occur mainly in the strata correlated with the Normalograptus extraordinarius graptolite Biozone. However, the uppermost finds of both taxa come from strata correlated with the N. persculptus Biozone.

    The 12th conference on "Variational Calculus, Optimal Control and Applications" took place September 23-27, 1996, in Trassenheide on the Baltic Sea island of Use­ dom. Seventy mathematicians from ten countries participated. The preceding eleven conferences, too, were held in places of natural beauty throughout West Pomerania; the first time, in 1972, in Zinnowitz, which is in the immediate area of Trassenheide. The conferences were founded, and led ten times, by Professor Bittner (Greifswald) and Professor KlCitzler (Leipzig), who both celebrated their 65th birthdays in 1996. The 12th conference in Trassenheide, was, therefore, also dedicated to L. Bittner and R. Klotzler. Both scientists made a lasting impression on control theory in the former GDR. Originally, the conferences served to promote the exchange of research results. In the first years, most of the lectures were theoretical, but in the last few conferences practical applications have been given more attention. Besides their pioneering theoretical...

  7. Past storminess recorded in the internal architecture of coastal formations of Estonia in the NE Baltic Sea region

    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

    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.

    The East Siberian Sea basin (ESSB) one of the most unexplored part of the Russian Arctic shelf, extending for over 1000 km from New Siberian Islands archipelago to Wrangel Island. This region is considered as a region with probable high petroleum potential. Within the ESSB several phases of orogeny are recognized [1]: Elsmerian orogeny in Early Devonian, Early Brooks orogeny in Early Cretaceous, Late Brooks orogeny in Late Cretaceous. Two generations of the basins could be outlined. Both of these generations are controlled by the basement domains [1]: Paleozoic (post-Devonian) to Mesozoic basins preserved north of the Late Mesozoic frontal thrusts; Aptian-Albian to Quaternary basins, postdating the Verkhoyansk-Brookian orogeny, and evolving mainly over the New-Siberian-Chukchi Fold Belt. Basin is filled with siliclastic sediments and in the deepest depocentres sediments thickness exceeds 8-10 km in average. Seismic data was interpreted using methods of seismic stratigraphy. Finally, main seismic horizons were indicated and each horizon follows regional stratigraphic unconformities: mBU - in base of Cenozoic, BU - in base of Upper Cretaceous, LCU - in base of Cretaceous, JU - in middle of Jurassic, F - in top of Basement. In ESSB, we can identify Permian, Triassic, Jurassic, Cretaceous, Paleogene and Neogene seismic stratigraphy complexes. Perspective structures, investigated in ESSB were founded out by comparing seismogeological cross-sections with explored analogs in other onshore and offshore basins [2, 3, 4]. The majority of structures could be connected with stratigraphic and fault traps. The most perspective prospects are probably connected with grabens and depressions, where thickness of sediments exceed 10 km. Reservoirs in ESSB are proposed by regional geological explorations on New Siberian Islands Archipelago and Wrangel Island. Potential seals are predominantly assigned to Jurassic and Cretaceous periods. Thick clinoform units of various geometry and

    Three different species of the Ordovician genus Erraticodon Dzik are described and illustrated. Erraticodon patu Cooper is reported from the Lower-Midde Ordovician strata of the Acoite and Alto del Cóndor formations. E. cf. Erraticodon balticus and Erraticodon hexianensis from Middle Ordovician carbonate deposits of the San Juan Formation are analyzed and compared to specimens of these species from Australia, China, Newfoundland, and Baltica. E. patu and E. hexianensis are recorded for first time in the San Juan Formation of Precordillera. The elements of E. cf. E. balticus resemble closely E. balticus Dzik but lack the important denticle on the posterior process of the S elements. An evaluation of the stratigraphic occurrences of these species relative to those of key Lower and Middle Ordovician conodont species such as Trapezognathus diprion Lindström, Oepikodus intermedius Serpagli, Baltoniodus triangularis (Lindström), Baltoniodus navis Lindström, Yangtzeplacognathus crassus (Chen and Zhang) and Eoplacognathus pseudoplanus (Viira) indicates they value for biostratigraphic correlation.

    To increase our understanding of long-term climate dynamics and its effects on different ecosystems, palaeoclimatic and long-term botanical reconstructions need to be improved, in particular in underutilized geographical regions. In this study, vegetation, (hydro)climate, and land-use changes were documented at two southeast Lithuanian peatland complexes - Čepkeliai and Rieznyčia - for the Late-Holocene period. The documentation was based on a combination of pollen, plant macrofossils, peat stratigraphic records, and subfossil trees. Our results cover the last two millennia and reveal the existence of moist conditions in Southern Lithuania between 300 and 500 CE and from 950 to 1850 CE. Conversely, changes towards warmer and/or dryer conditions have been recorded in 100, 600, and 750 CE, and since the 1850s. Significant differences with other Baltic proxies prevent deriving a complete and precise long-term reconstruction of past hydroclimatic variability at the regional scale. Yet, our results provide an important cornerstone for an improved understanding of regional climate change, i.e. in a region for which only (i) few detailed palaeobotanical studies exist and which has, in addition, been considered as (ii) an ecologically sensitive region at the interface between the temperate and boreal bioclimatic zones.

  19. 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

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

    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

    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

    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

  13. Baltic States in NATO: Results of the Decade

    Directory of Open Access Journals (Sweden)

    Vladislav V. Vorotnikov

    2014-01-01

    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.

  15. Implementation of the NEMO model for estimating the spread of leakage from chemical munitions in the Baltic Sea - the first approach

    Science.gov (United States)

    Andrzejewski, Jan

    2017-04-01

    After the Second World War, during the Potsdam Conference a decision about demilitarization of Germany was made, and as a consequence, ammunition including chemical warfare agents (CWA) was dumped into the basins of the Baltic Sea. This type of weapon was stored in metal barrels that were under strong influence of electrochemical oxidation, also known as corrosion. Several tens years later, scientists were wondering what consequences for marine ecosystem could a leakage from this weapon bring. Although over 70 years passed since the Second World War, the influence of potential leakage of the CWA has not been properly estimated. Thus, the main goal of this work is to estimate dangerous area caused by potential leakage using the NEMO (Nucleus for European Modelling of the Ocean) ocean model. The NEMO ocean model is developed by the European Consortium including research institutes from France, England and Italy. The first step of this work is to implement the model for the area of the Baltic Sea. It requires generation of horizontal and vertical grid, bathymetry, atmospheric forces and lateral boundary conditions. Implemented model will have to be checked - it means it will have to pass a validation process. The Baltic Sea is one of the best measured sea in the World - as a consequence a lot of data are freely available for researchers. After validation and tuning up the model, implementation of passive tracer is planned. Passive tracer is the prognostic variable that could represent concentration of potential leakage and does not have influence on the density of the model. Based on distribution of the passive tracer, dangerous areas in the locations of dumpsites will be assessed. The research work was funded by the European Union (European Regional Development Fund) under the Interreg Baltic Sea Region Programme 2014-2020, project #R013 DAIMON (Decision Aid for Marine Munitions).

  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

  14. The Influence of Stratigraphic History on Landscape Evolution

    Science.gov (United States)

    Forte, A. M.; Yanites, B.; Whipple, K. X.

    2016-12-01

    Variation in rock erodibility can play a significant role in landscape evolution. Using a version of the CHILD landscape evolution model that allows for variations in rock erodibility, we found surprisingly complex landscape evolution in simulations with simple, two unit stratigraphies with contrasting erodibility. This work indicated that the stratigraphic order of units in terms of erodibility, the orientation of the contact with respect to the main drainage direction, and the contact dip angle all have pronounced effects on landscape evolution. Here we expand that work to explore the implications of more complicated stratigraphies on landscape evolution. Introducing multiple units adds additional controls on landscape evolution, namely the thicknesses and relative erodibility of rock layers. In models with a sequence of five alternating hard and soft units embedded within arbitrarily thick over- and underlying units, the number of individual layers that noticeably influence landscape morphology decreases as the thickness of individual layers reduces. Contacts with soft rocks over hard produce the most noticeable effect in model output such as erosion rate and channel steepness. For large contrasts in erodibility of 25 m thick layers, only one soft over hard contact is clearly manifest in the landscape. Between 50 and 75 m, two such contacts are manifest, and by 100 m thickness, all three of these contacts are manifest. However, for a given thickness of layers, more units are manifest in the landscape as the erodibility contrast between units decreases. This is true even though the magnitude of landscape effects away from steady-state erosion rates or channel steepness also decrease with decreasing erodibility contrast. Finally, we explore suites of models with alternating layers reflecting either `hardening-' or `softening-upwards' stratigraphies and find that the two scenarios result in decidedly different landscape forms. Hardening-upwards sections produce a

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.

    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...

    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.

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

    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

    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

    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...

    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.

  6. Shaping Baltic States Defence Strategy: Host Nation Support

    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.

    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.

    Contamination of sandy beaches of the Baltic Sea in Kaliningrad region is evaluated on the base of surveys carried out from June 2015 to January 2016. 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.

    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.

    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...

  13. 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)

    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.

  18. 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.

    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.

    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)

    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

AREA is a coalition of industry, labour and municipalities from across Canada which was created to reflect the views and represent the interests of Canadians in the Climate Change Debate. Ways and means of optimizing Canada's response to the Global Climate Change Challenge were discussed. Discussions emphasized issues regarding the effectiveness of voluntary mechanisms to reduce greenhouse gases, as opposed to government-mandated actions for achieving climate change targets. The issue of how a differentiated system for emission reduction targets and timetables can be implemented was also debated. The economic implications of climate change were outlined. Canada's national agenda and the likely outcomes of the Conference of Parties (COP 4) in Buenos Aires also received much attention. tabs., figs

It was the ninth in the series of meetings organized in the USA which differ from the 'International' meetings in their coverage of the full range of accelerator engineering and technology, including applications outside e field of high energy physics. The Conference took place under the cloud of further budget cuts for Fiscal Year 1982 in the USA which the Department of Energy has applied in line with the financial policy of the new administration. Coming on top of many years of budget trimming which have reduced the number of high energy physics Laboratories funded by the DOE to three (Brookhaven, Fermilab, Stanford - Cornell is funded by the National Science Foundation) and reduced the exploitation of these Laboratories to less than half of their potential, the new cuts did not exactly help to boost morale. Nevertheless, the huge amount of tailed work in accelerator physics and technology which was presented at the Conference showed how alive the field is

  9. Student learning and understanding of sequence stratigraphic principles

    Science.gov (United States)

    Herrera, Juan Sebastian

    Research in geoscience education addressing students' conceptions of geological subjects has concentrated in topics such as geological time, plate tectonics, and problem solving in the field, mostly in K-12 and entry level college scenarios. Science education research addressing learning of sedimentary systems in advance undergraduates is rather limited. Therefore, this dissertation contributed to filling that research gap and explored students' narratives when explaining geological processes associated with the interaction between sediment deposition and sea level fluctuations. The purpose of the present study was to identify the common conceptions and alternative conceptions held by students when learning the basics of the sub discipline known as sequence stratigraphy - which concepts students were familiar and easily identified, and which ones they had more difficulty with. In addition, we mapped the cognitive models that underlie those conceptions by analyzing students' gestures and conceptual metaphors used in their explanations. This research also investigated the interaction between geoscientific visual displays and student gesturing in a specific learning context. In this research, an in-depth assessment of 27 students' ideas of the basic principles of sequence stratigraphy was completed. Participants were enrolled in advanced undergraduate stratigraphy courses at three research-intensive universities in Midwest U.S. Data collection methods included semi-structured interviews, spatial visualization tests, and lab assignments. Results indicated that students poorly integrated temporal and spatial scales in their sequence stratigraphic models, and that many alternative conceptions were more deeply rooted than others, especially those related to eustasy and base level. In order to better understand the depth of these conceptions, we aligned the analysis of gesture with the theory of conceptual metaphor to recognize the use of mental models known as image

    2001-08-01

    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.

  11. Kas "balti kirjanik" on olemas? / Does the "Baltic Writer" Exist?

    Full Text Available Teesid: Artiklis küsitakse 2009. a ilmunud leksikoni „300 Baltic Writers“ põhjal, kas „Balti kirjanik“ on põhjendatud mõiste. 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

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

    Directory of Open Access Journals (Sweden)

    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.

  2. 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.

  3. EIA in the Baltic countries. The case of three oil terminals

    1995-12-31

    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)

    Full Text Available Since the “Tenth Five-Year Plan”, lithologic and stratigraphic reservoirs have been the main contribution of both the discovery as well as reserve and production increase in China; there were about 80% of proven reserves. The typical reservoirs in six major basins in the eastern, central, and western China were adopted as reservoir forming models. The reservoir forming models in three types of slopes, three types of depressions, and three types of lithologic reservoir assemblages have been built on the basis of application of new technologies, physical modeling of reservoir forming mechanism, and investigation to the formation and distribution of the reservoirs. The evaluation methods for large lithologic reservoirs provinces were established based on the forming mechanism and main controlling factors mentioned above. In addition, the study reveals the main controlling factors and the laws of enrichment of two types of stratigraphic reservoirs (pinch-out and weathered karst reservoirs based on the evaluation methods for large stratigraphic reservoir provinces that have been established. By comprehensively understanding the laws of enrichment of lithologic-stratigraphic reservoirs in four types of basins, specific evaluation methods and fine exploration techniques have been developed. The findings led to an exploration direction in the “Thirteenth Five-Year Plan” period. The study supported the exploration and selection of oil and gas plays, as well as promoted the exploration of lithologic and stratigraphic reservoirs.

    Lithologic variation, regional depositional trends, and the lack of written guidelines have resulted in inconsistencies in the recognition of stratigraphic contacts in drill holes at the Nevada Test Site (NTS). Stratigraphic identification, based on mineralogy of discrete samples, can be augmented by geophysical logs and downhole movies to more accurately and consistently locate contacts between units. Criteria are established for locating the base of the Pahute Mesa ash-flow tuff, the top of the Ammonia Tanks ash-flow tuff, the top of the Ammonia Tanks bedded tuff, and the top and the base of the Rainier Mesa Tuff

    Stratigraphic profiles were constructed for eight selected Hanford Site seismometer stations, five Hanford Site facility reference locations, and seven regional three-component broadband seismometer stations. These profiles provide interpretations of the subsurface layers to support estimation of ground motions from past earthquakes, and the prediction of ground motions from future earthquakes. In most cases these profiles terminated at the top of the Wanapum Basalt, but at selected sites profiles were extended down to the top of the crystalline basement. The composite one-dimensional stratigraphic profiles were based primarily on previous interpretations from nearby boreholes, and in many cases the nearest deep borehole is located kilometers away.

  15. Microplastics in the Baltic Sea water: fibers everywhere.

    Science.gov (United States)

    Khatmullina, Lilia; Bagaev, Andrey; Chubarenko, Irina

    2017-04-01

    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. The research is supported by the Russian Science Foundation grant number 15-17-10020.

  16. Acid-base properties of Baltic Sea dissolved organic matter

    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.

  17. Solar radiation at the surface in the Baltic Proper

    2010-12-01

    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.

  18. Renewable energy in the Baltic countries: the case of hydropower

    International Nuclear Information System (INIS)

    Punys, P.; Dumbrauskas, A.; Rimkus, Z.; Streimikiene, D.

    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.

This is a region of low light and prey availability, hence generating the hypothesis that larvae have to migrate from hatching depth to the surface layer to avoid starvation and improve their nutritional condition...... aged 2-25 days (median 10 days) ranged from 0.4 to 6.2, corresponding to levels exhibited by starving and fast growing larvae in laboratory calibration studies (starvation, protein growth rate, G(pi)=-12.2% day(-1); fast-growing larvae, G(pi)=14.1% day(-1)) respectively. Seventy per cent of the field...

  3. Has eutrophication promoted forage fish production in the Baltic Sea?

    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...

  6. Cairo conference.

    1994-09-03

    The United Nations Conference on Population and Development in Cairo in September, 1994, will evoke criticism of the inability of governments to act quickly enough to avert demographic and environmental crises. Rapid population growth has clear implications for public health. Globally there now occur anthropogenic changes in atmospheric composition, the degradation of fertile lands and ocean fisheries, an accelerating loss of biodiversity, and the social and ecological problems of massive urbanization. In the future, per capita consumption levels will increase in burgeoning populations of developing countries, thus adding to the environmental impacts of overconsuming rich countries. By the end of the decade there will be over six billion people, of whom one half will live in cities. These demographic and environmental trends, if translated into climatic change, regional food shortages, and weakened ecosystems, would adversely affect human health. The World Health Organization is likely to concentrate only on accessible family planning and promotion of health for women and families. Continuing asymmetric child-saving aid, unaccompanied by substantial aid to help mobilize the social and economic resources needed to reduce fertility, may delay the demographic transition in poor countries and potentiate future public health disasters. As a result of recent reductions in fertility, even in Sub-Saharan Africa, average family sizes have been halved. Yet the demographic momentum will double population by 2050. The biosphere is a complex of ecosystems and, if unsustained, it could not fulfill the productive, cleansing, and protective functions on which life depends. The Cairo conference must therefore recognize that sustaining human health is a prime reason for concern about population growth and models of economic development.

  7. Trauma research in the Baltic countries: from political oppression to recovery.

    2016-01-01

    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.

  8. Atmospheric forcing of decadal Baltic Sea level variability in the last 200 years. A statistical analysis

    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

  9. Electric energy cooperation in the Baltic Sea region and the role of Russia in it

    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.

    The summaries were derived from presentations, interviews and discussions at the conference. The summaries are given at two levels, overall for the conference and for specific sessions as follows: 1) Overall Conference: 'A Sound Scientific Basis for Serious Decisions; 2) Sessions on EC Policy and Socio-Political Issues: 'Promoting Safety and Protecting Society'; 3) Session on P and T: 'Partitioning and Transmutation: A Technical Fix or Technical Training?'; 4) Sessions on Geological Disposal and Research Networking: 'No Technical Barriers to Geological Disposal'. First an overall summary of Euradwaste '04 is presented. Significant progress was made on the technical and scientific basis for geological disposal of radioactive waste during the European Commission's Fifth EURATOM Framework Programme for Research (FP5). Deep geological disposal is technically feasible now and can demonstrate the guarantees of long-term isolation and protection of the public. In parallel, socio-political studies have produced methodologies for constructive dialogue with potential host communities that reflect the honesty and openness expected by a democratic society. A harmonized legislative framework for nuclear safety and waste disposal across the enlarged European Union is currently being discussed. Disposal in deep (> 300 metre) geological repositories, the favoured strategy in Europe for long-lived high-level radioactive waste, is now possible. The Sessions on EC Policy and Socio-Political Issues are summarized as follows. The opening day of Euradwaste '04 focused on European Commission policy, including the proposed Directives on disposal of radioactive waste and nuclear safety and socio-political aspects including governance and decision making, public perception/acceptance of waste disposal and its sustainability. A decision on the proposed package will now be made after Union enlargement. Public agreement on the siting of

    2015-04-01

    Since the foundation of stratigraphy geoscientists have recognized that data obtained from stratigraphic columns (SC), two dimensional schemes recording descriptions of both geological and paleontological features (e.g., thickness of rock packages, grain size, fossil and lithological components, and sedimentary structures), are key elements for establishing reliable hypotheses about the distribution in space and time of rock sequences, and ancient sedimentary environmental and paleobiological dynamics. Despite the tremendous advances on the way geoscientists store, plot, and quantitatively analyze sedimentological and paleontological data (e.g., Macrostrat [http://www.macrostrat.org/], Paleobiology Database [http://www.paleodb.org/], respectively), there is still a lack of computational methodologies designed to quantitatively examine data from a highly detailed SCs. Moreover, frequently the stratigraphic information is plotted "manually" using vector graphics editors (e.g., Corel Draw, Illustrator), however, this information although store on a digital format, cannot be used readily for any quantitative analysis. Therefore, any attempt to examine the stratigraphic data in an analytical fashion necessarily takes further steps. Given these issues, we have developed the sofware 'Stratigraphic Data Analysis in R' (SDAR), which stores in a database all sedimentological, stratigraphic, and paleontological information collected from a SC, allowing users to generate high-quality graphic plots (including one or multiple features stored in the database). SDAR also encompasses quantitative analyses helping users to quantify stratigraphic information (e.g. grain size, sorting and rounding, proportion of sand/shale). Finally, given that the SDAR analysis module, has been written in the open-source high-level computer language "R graphics/statistics language" [R Development Core Team, 2014], it is already loaded with many of the crucial features required to accomplish basic and

    We investigate the subsurface data of a large sector in the Sidoarjo district (East Java, Indonesia) where the sudden catastrophic Lusi eruption started the 26th May 2006. Our goal is to understand the stratigraphic and structural features which can be genetically related to the surface manifestations of deep hydrothermal fluids and thus allow us to predict possible future similar phenomena in the region. In the framework of the Lusi Lab project (ERC grant n° 308126) we examined a series of densely spaced 2D reflection commercial seismic lines This allowed the reconstruction of the lateral variability of key stratigraphic horizons as well as the main tectonic features. In particular, we shed light on the deep structure of the Watukosek fault system and the associated fracture corridors crossing the entire stratigraphic successions. To the South-West, when approaching the volcanic complex, we could identify a clear contrast in seismic facies between chaotic volcanoclastic wedges and clastic-prone sedimentary successions as well as between the deeper stratigraphic units consisting of carbonates and lateral shales units. The latter show possible ductile deformation associated to fault-controlled diapirism which control in turns deformation of overlying stratigraphic units and deep geo-fluids circulation. Large collapse structures recognized in the study area (e.g. well PRG-1) are interpreted as the results of shale movement at depth. Similarly to Lusi, vertical deformation zones ("pipes"), likely associated with deeply rooted strike-slip systems seem to be often located at the interface between harder carbonate rocks forming isolated build ups and the laterally nearby clastic (shale-prone)-units. The mechanisms of deformation of structural features (strike vs dip slip systems) which may affect either the basement rock or the overlying deeper stratigraphic rocks is also being investigated to understand the relationship between deep and shallower (i.e. meteoric) fluid

    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.

    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.

    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.

    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.

  19. Renewable Energy in the Baltic States. Different Situations

    Streimikiene, Dalia

    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.

    2004-05-01

    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.

    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.

  5. 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.

    A Swedish research programme concerning the Baltic Sea is initiated by the SNV to produce budgets and models of eutrophying substances (nitrogen, phosphorus, silicate, some organic substances) and toxic substances (PCB, lindane and PAH). A description of the distribution and turnover of these substances including their transformation will be necessary in the evaluation of critical processes controlling concentrations in relation to external load. A geographical information system will be made available as a database and analytical tool for all participants (BED, Baltic Ecosystem Data). This project is designed around cooperation between the Baltic Sea countries. (au)

    This thesis present the extension of mono-component seismic pre-stack data stratigraphical inversion method to multicomponent data, with the objective of improving the determination of reservoir elastic parameters. In addiction to the PP pressure waves, the PS converted waves proved their interest for imaging under gas clouds; and their potential is highly significant for the characterization of lithologies, fluids, fractures... Nevertheless the simultaneous use ol PP and PS data remains problematic because of their different the time scales. To jointly use the information contained in PP and PS data, we propose a method in three steps first, mono-component stratigraphic inversions of PP then PS data; second, estimation of the PP to PS time conversion law; third, multicomponent stratigraphic inversion. For the second point, the estimation of the PP to PS conversion law is based on minimizing the difference between the S impedances obtained from PP and PS mono-component stratigraphic inversion. The pre-stack mono-component stratigraphic inversions was adapted to the case of multicomponent data by leaving each type of data in its own time scale in order to avoid the distortion of the seismic wavelet. The results obtained on a realistic synthetic PP-PS case show on one hand that determining PP to PS conversion law (from the mono-component inversion results) is feasible, and on the other hand that the joint inversion of PP and PS data with this conversion law improves the results compared to the mono-component inversion ones. Although this is presented within the framework of the PP and PS multi-component data, the developed methodology adapts directly to PP and SS data for example. (author)

  12. Automated recognition of stratigraphic marker shales from geophysical logs in iron ore deposits

    The mining of stratiform ore deposits requires a means of determining the location of stratigraphic boundaries. A variety of geophysical logs may provide the required data but, in the case of banded iron formation hosted iron ore deposits in the Hamersley Ranges of Western Australia, only one geophysical log type (natural gamma) is collected for this purpose. The information from these logs is currently processed by slow manual interpretation. In this paper we present an alternative method of automatically identifying recurring stratigraphic markers in natural gamma logs from multiple drill holes. Our approach is demonstrated using natural gamma geophysical logs that contain features corresponding to the presence of stratigraphically important marker shales. The host stratigraphic sequence is highly consistent throughout the Hamersley and the marker shales can therefore be used to identify the stratigraphic location of the banded iron formation (BIF) or BIF hosted ore. The marker shales are identified using Gaussian Processes (GP) trained by either manual or active learning methods and the results are compared to the existing geological interpretation. The manual method involves the user selecting the signatures for improving the library, whereas the active learning method uses the measure of uncertainty provided by the GP to select specific examples for the user to consider for addition. The results demonstrate that both GP methods can identify a feature, but the active learning approach has several benefits over the manual method. These benefits include greater accuracy in the identified signatures, faster library building, and an objective approach for selecting signatures that includes the full range of signatures across a deposit in the library. When using the active learning method, it was found that the current manual interpretation could be replaced in 78.4% of the holes with an accuracy of 95.7%.

  13. Sequence stratigraphy in the middle Ordovician shale successions, mid-east Korea: Stratigraphic variations and preservation potential of organic matter within a sequence stratigraphic framework

    Science.gov (United States)

    2018-02-01

    The Jigunsan Formation is the middle Ordovician shale-dominated transgressive succession in the Taebaeksan Basin, located in the eastern margin of the North China platform. The total organic carbon (TOC) content and some geochemical properties of the succession exhibit a stratigraphically distinct distribution pattern. The pattern was closely associated with the redox conditions related to decomposition, bulk sedimentation rate (dilution), and productivity. To explain the distinct distribution pattern, this study attempted to construct a high-resolution sequence stratigraphic framework for the Jigunsan Formation. The shale-dominated Jigunsan Formation comprises a lower layer of dark gray shale, deposited during transgression, and an upper layer of greenish gray siltstone, deposited during highstand and falling stage systems tracts. The concept of a back-stepped carbonate platform is adopted to distinguish early and late transgressive systems tracts (early and late TST) in this study, whereas the highstand systems tracts and falling stage systems tracts can be divided by changes in stacking patterns from aggradation to progradation. The late TST would be initiated on a rapidly back-stepping surface of sediments and, just above the surface, exhibits a high peak in TOC content, followed by a gradually upward decrease. This trend of TOC distribution in the late TST continues to the maximum flooding surface (MFS). The perplexing TOC distribution pattern within the late TST most likely resulted from both a gradual reduction in productivity during the late TST and a gradual increase in dilution effect near the MFS interval. The reduced production of organic matter primarily incurred decreasing TOC content toward the MFS when the productivity was mainly governed by benthic biota because planktonic organisms were not widespread in the Ordovician. Results of this study will help improve the understanding of the source rock distribution in mixed carbonate

    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.

    Full Text Available Reefs and a barrier reef have been newly identified and mapped by three-dimensional (3D seismic survey in Lithuania. Seismic data analysis has allowed the size and geometry of these reefs to be determined. The largest reefs occur at Pavasaris and South Bliudziai. They have a similar shape and are about 1.5 km long and 1 km wide. A circle-shaped smaller patch reef at North Bliudziai is 1 km in diameter. The overall heights of the studied structures do not exceed 30–40 m. The reefs consist of coarse-grained bioclastic stromatoporoid limestone. A barrier reef rising structurally from SW to NE was established in the west of the mapped area. The stratigraphic position (early Minija Regional Stage and lateral distribution of the barrier reef suggest it started to form earlier than the group of patch reefs. The development of patch reefs was related to the transgression of the Silurian Baltic basin.

    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.

    The main goal of our research is the high-resolution reconstruction of environmental and climatic changes in SE Baltic region since the Last Glacial Maximum by palaeolimnological data. The 6 objects - lakes and peat-bogs, were studied since 2009 in the Kaliningrad region, Russian Federation. According to palaeolimnological studies of bottom sediments of the Kamyshovoe Lake (N 54°22,6`; E22°42,8`, 189 m a.s.l.), located in the Vishtynets Highland, the south-east part of Kaliningrad district, the environmental and climatic changes after the late glacial have been reconstructed. At that moment the radiocarbon and loss-on-ignition (LOI) data, geochemistry and diatom analysis for the whole sediment core, and pollen analyze for the bottom part of the core have been completed. According to the pollen data the Alleröd interstadial starts at 13 200 cal. yrs BP and is marked by the rising of birch and pine pollen. The transition to the Younger Dryas around 12 700 cal. yrs BP corresponds with the development of patches of shrublands in which light-demanding species, such as juniper, flourished and communities of steppe herbs. The late Preboreal is marked by the appearance of Populus and an increase of the role of grasses in the vegetation cover 11 300-11 100 cal. yrs BP (Druzinina et al., 2015). The Holocene climatic zones have been identified by LOI and geochemistry analyses. The Boreal period started about 10 200 cal. yrs BP, Atlantic around 9100 cal. yrs BP, Subboreal 5800 cal. yrs BP, and Subatlantic 3200 cal. yrs BP (Kublitskiy et al., 2015). During the conference the new palaeolimnological data of environmental variability during the late Pleistocene and Holocene in SE Baltic region will be presented.

    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.

    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.

    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 ...

    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.

  20. Individual doses from radionuclides released to the Baltic coast

    Bergstroem, U.; Nordlinder, S.

    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.

    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.

    2017-01-30

    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.

    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.

    1985-01-01

    The paper presents data on the level of benzo(a)pyrene (BP) and some other polycyclic arenes in alga and phanerogam specimens from different gulfs of the Baltic Sea. Algae were shown to absorb BP from sea water. The mean concentration of BP in sea water was under 0.004 microgram/1, while in algae it ranged 0.1-21.2 micrograms/kg dry weight. Algae accumulate BP to a higher degree than phanerogams. The highest concentrations of BP were found in algae Enteromorpha while the lowest ones in Furcellaria. In annual green algae, BP level was higher in autumn, i. e. at the end of vegetation period, than in spring. Brown algae Fucus vesiculosus is recommended for monitoring polycyclic arene pollution in the area from Vormsi Island to Kaesmu and green algae Cladophora or Enteromorpha in the eastern part of the Finnish Gulf.

    2016-04-01

    Suspended matter grain size data were gathered during the 25th research vessel "Akademik Mstislav Keldysh" cruise (1991, September-October). Initial quantitative data were obtained with a use of the Coulter counter and subsequently modified into volume concentrations (mm3/l) for size intervals. More than 80 samples from 15 stations were analyzed (depth range 0-355 m). The main goal of research was to illustrate the spatial variability of suspended matter concentration and dispersion in Baltic Sea. The mutual feature of suspended matter grain size distribution is the logical rise of particle number along with descending of particle's size. Vertical variability of grain size distribution was defined by Baltic Sea hydrological structure, including upper mixed layer - from the surface to the thermocline - with 35 m thick, cold intermediate layer - from the thermocline to the halocline- and bottom layer, which lied under the halocline. Upper layer showed a rise in total suspended matter concentration (up to 0.6 mm3/l), while cold intermediate level consisted of far more clear water (up to 0.1 mm3/l). Such a difference is caused by the thermocline boarding role. Meanwhile, deep bottom water experienced surges in suspended matter concentration owing to the nepheloid layer presence and "liquid bottom" effect. Coastal waters appeared to have the highest amount of particles (up to 5.0 mm3/l). Suspended matter grain size distribution in the upper mixed layer revealed a peak of concentration at 7 μ, which can be due to autumn plankton bloom. Another feature in suspended matter grain size distribution appeared at the deep layer below halocline, where both O2 and H2S were observed and red/ox barrier is. The simultaneous presence of Fe and Mn (in solutions below red/ox barrier) and O2 leads to precipitation of oxyhydrates Fe and Mn and grain size distribution graph peaking at 4.5 μ.

  12. Spectrophotometric studies of marine surfactants in the southern Baltic Sea

    2015-04-01

    Full Text Available It is well known that surfactants in the southern Baltic Sea constitute the organic matter from riverine waters discharges as well as the secondary degradation products of marine phytoplankton excretion. They reach the surface microlayer by the upwellings and turbulent motions of water and in the membranes of the vesicles as well as from the atmosphere. To assess concentration and spatial distribution of marine surfactants in the southern Baltic Sea, the steady-state spectrophotometric and spectrofluorometric measurements of water samples taken from a surface film and a depth of 0.5 m were carried out. Water samples were collected during windless days of the cruise of r/v ‘Oceania’ in November 2012, from the open and the coastal waters having regard to the vicinity of the Vistula and Łeba mouths. In the present paper, fractions of dissolved organic matter having chromophores (CDOM or fluorophores (FDOM are recognized through their specific spectroscopic behavior, i.e., steady-state absorption, fluorescence excitation and fluorescence spectra. The steady-state spectroscopic measurements revealed the CDOM and FDOM molecules characteristic to both the land and marine origin. Moreover, the concentration and spatial distribution of marine surfactants significantly depend on the distance from the river mouth. Finally, higher values of absorbance and fluorescence intensity observed in a surface film in comparison to these values in a depth of 0.5 m clearly suggest the higher concentration of organic matter in a marine film. On the other hand, our results revealed that a surface microlayer is composed of the same CDOM and FDOM as bulk water.

    1988-05-01

    Monitoring of radioactive substances in the Baltic Sea was continued within the framework of the Finnish national monitoring programme. The only regularly detected gamma nuclides in sea water were 40 K, 134 Cs and 137 Cs. The ratio 134 Cs/ 137 Cs in surface water samples was 0.36+-0.01. The activity concentrations of 137 Cs have became more evenly distributed during the last year, so that in the surface water of the Baltic Proper the values were 100-200 Bq m -3 , in the Gulf of Finland 200-300 Bq m -3 , in the Bothnian Sea 300-400 Bq m -3 and in the Bothnian Bay about 100 Bq m -3 in 1987. The sedimentation of the Chernobyl fallout into the bottom sediments of the open sea basins only began to increase in 1987. The addition of 137 Cs and other fallout nuclides was strongest at the XV 1 station in the eastern part of the Gulf of Finland, where the total deposition of 137 Cs was about 18 kBq m -3 during the last year. No areal differences were found in the fish samples caught from the coastal waters of Finland in 1987. In pike and cod the 137 Cs values have slightly increased since 1986, being now about five times (15-30 Bq kg -1 fresh weight) the values before the Chernobyl accident. The activity concentrations of 90 Sr (0.030-0.11 Bq kg -1 fresh weight) were at the same level as in 1985 and the preceding years

    Full Text Available The Natura 2000 sites and the Coastal Landscape Park in a shallow marine bay in the southern Baltic have been studied in detail for the distribution of benthic macroorganisms, species assemblages and seabed habitats. The relatively small Inner Puck Bay (104.8 km2 is one of the most thoroughly investigated marine areas in the Baltic: research has been carried out there continuously for over 50 years. Six physical parameters regarded as critically important for the marine benthos (depth, minimal temperature, maximum salinity, light, wave intensity and sediment type were summarized on a GIS map showing unified patches of seabed and the near-bottom water conditions. The occurrence of uniform seabed forms is weakly correlated with the distributions of individual species or multi-species assemblages. This is partly explained by the characteristics of the local macrofauna, which is dominated by highly tolerant, eurytopic species with opportunistic strategies. The history and timing of the assemblage formation also explains this weak correlation. The distribution of assemblages formed by long-living, structural species (Zostera marina and other higher plants shows the history of recovery following earlier disturbances. In the study area, these communities are still in the stage of recovery and recolonization, and their present distribution does not as yet match the distribution of the physical environmental conditions favourable to them. Our results show up the limitations of distribution modelling in coastal waters, where the history of anthropogenic disturbances can distort the picture of the present-day environmental control of biota distributions.

    2004-01-01

    This paper presents a stratigraphic and tectonic revision of Cerro Olivo Complex, located in the Southeastern part of the Uruguayan Predevonian Shield. This informal lithostratigraphic unit constitutes the country rock for the emplacement of late-orogenic granitoids, during Neoproterozoic to Cambrian times. This unit groups all the lithodemes affected by deformation and metamorphism. Recent studies indicate the presence of straight gneisses of quartzo-feldspathic composition in the coast of Maldonado Department. These rocks were interpreted as the result of intense deformation in high temperature. These tectonites base a new stratigraphic insight for the complex. They allow their lithotypes to be organized by petrotectonic features, being a function of PT conditions for every last strain process [es

  17. Life on the margin: genetic isolation and diversity loss in a peripheral marine ecosystem, the Baltic Sea.

    2006-07-01

    Marginal populations are often isolated and under extreme selection pressures resulting in anomalous genetics. Consequently, ecosystems that are geographically and ecologically marginal might have a large share of genetically atypical populations, in need of particular concern in management of these ecosystems. To test this prediction, we analysed genetic data from 29 species inhabiting the low saline Baltic Sea, a geographically and ecologically marginal ecosystem. On average Baltic populations had lost genetic diversity compared to Atlantic populations: a pattern unrelated to dispersal capacity, generation time of species and taxonomic group of organism, but strongly related to type of genetic marker (mitochondrial DNA loci had lost c. 50% diversity, and nuclear loci 10%). Analyses of genetic isolation by geographic distance revealed clinal patterns of differentiation between Baltic and Atlantic regions. For a majority of species, clines were sigmoid with a sharp slope around the Baltic Sea entrance, indicating impeded gene flows between Baltic and Atlantic populations. Some species showed signs of allele frequencies being perturbed at the edge of their distribution inside the Baltic Sea. Despite the short geological history of the Baltic Sea (8000 years), populations inhabiting the Baltic have evolved substantially different from Atlantic populations, probably as a consequence of isolation and bottlenecks, as well as selection on adaptive traits. In addition, the Baltic Sea also acts a refuge for unique evolutionary lineages. This marginal ecosystem is thus vulnerable but also exceedingly valuable, housing unique genes, genotypes and populations that constitute an important genetic resource for management and conservation.

  19. Revised Cretaceous and Tertiary stratigraphic nomenclature in the Colville Basin, Northern Alaska

    Science.gov (United States)

    Mull, Charles G.; Houseknecht, David W.; Bird, Kenneth J.

    2003-01-01

    A revised stratigraphic nomenclature is proposed for Cretaceous and Tertiary geologic units of the central and western North Slope of Alaska. This revised nomenclature is a simplified and broadly applicable scheme suitable for a suite of digital geologic quadrangle maps being prepared jointly by the U.S. Geological Survey and the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys and Division of Oil and Gas. This revised nomenclature scheme is a simplification of a complex stratigraphic terminology that developed piecemeal during five decades of geologic investigations of the North Slope. It is based on helicopter-supported geologic field investigations incorporating information from high-resolution aerial photography, satellite imagery, paleontology, reflection seismic records, and sequence stratigraphic concepts. This revised nomenclature proposes the abandonment of the Colville Group; demotion of the Nanushuk Group to formation status; abandonment of six formations (Kukpowruk, Tuktu, Grandstand, Corwin, Chandler, and Ninuluk); revision of four formations (Sagavanirktok, Prince Creek, Schrader Bluff, and Seabee); elevation of the Tuluvak Tongue of the Prince Creek Formation to formation status; revision of two members (Franklin Bluffs Member and Sagwon Member of the Sagavanirktok Formation); abandonment of eight members or tongues (Kogosukruk, Rogers Creek, Barrow Trail, Sentinel Hill, Ayiyak, Shale Wall, Niakogon, and Killik); and definition of one new member (White Hills Member of the Sagavanirktok Formation).

    1987-01-01

    This site study describes the Stratigraphic Boreholes field work to be conducted during the early stages of Site Characterization at the Deaf Smith County, Texas site. The field program has been designed to provide data useful in addressing information/data needs resulting from Federal/State/local regulations, and repository program requirements. Four Stratigraphic Holes will be drilled near the perimeter of the site to document the subsurface geologic conditions in that area and to provide data necessary for design and construction of the Exploratory Shaft Facilities. Continuous samples will be recovered from the ground surface to the total depth of each sell. Geophysical well logs will provide additional coverage of the stratigraphic section. In-situ down hole testing will include short term hydrologic tests and hydraulic fracture tests to provide information on deep groundwater characteristics and regional stress patterns, respectively. Field methods/tests are chosen that provide the best or only means of obtaining the required data. The Salt Repository Project (SRP) Networks specify the schedule which the program will operate. The Technical Services Contractor is responsible for conducting the field program of drilling and testing. Samples and data will be handled and reported in accordance with established SRP procedures. A quality assurance program will be utilized to assure that activities affecting quality are performed correctly and that the appropriate documentation is maintained. 30 refs., 13 figs., 4 tabs

  1. A method of reconstructing complex stratigraphic surfaces with multitype fault constraints

    Deng, Shi-Wu; Jia, Yu; Yao, Xing-Miao; Liu, Zhi-Ning

    2017-06-01

    The construction of complex stratigraphic surfaces is widely employed in many fields, such as petroleum exploration, geological modeling, and geological structure analysis. It also serves as an important foundation for data visualization and visual analysis in these fields. The existing surface construction methods have several deficiencies and face various difficulties, such as the presence of multitype faults and roughness of resulting surfaces. In this paper, a surface modeling method that uses geometric partial differential equations (PDEs) is introduced for the construction of stratigraphic surfaces. It effectively solves the problem of surface roughness caused by the irregularity of stratigraphic data distribution. To cope with the presence of multitype complex faults, a two-way projection algorithm between threedimensional space and a two-dimensional plane is proposed. Using this algorithm, a unified method based on geometric PDEs is developed for dealing with multitype faults. Moreover, the corresponding geometric PDE is derived, and an algorithm based on an evolutionary solution is developed. The algorithm proposed for constructing spatial surfaces with real data verifies its computational efficiency and its ability to handle irregular data distribution. In particular, it can reconstruct faulty surfaces, especially those with overthrust faults.

    In recent years, the exploratory interest on Cumuruxatiba Basin has been inconstant, with modest discoveries of oil. Aiming to deepen the geological knowledge of the basin and in order to attract the interest of oil companies, the ANP (National Agency of Petroleum, Natural Gas and Biofuels) signed contract with COPPE/UFRJ for carrying out an analysis basin project. The project was developed by the Basin Analysis Multidisciplinary Modeling Laboratory (Lab2M/UFRJ) in the period 2006/2007, and was with the main objective outline the main structural and seismo-stratigraphic features of the basin, and in an integrated and multidisciplinary way, build a model of its sedimentation and tectono-stratigraphic evolution. This paper presents the results of the regional seismic mapping, aided by well and potential methods data.

    Hill-hole pairs, comprising an ice-pushed hill and associated source depression, cluster in a belt along the west coast of Banks Island, NT. Ongoing coastal erosion at Worth Point, southwest Banks Island, has exposed a section (6 km long and ˜30 m high) through an ice-pushed hill that was transported ˜ 2 km from a corresponding source depression to the southeast. The exposed stratigraphic sequence is polydeformed and comprises folded and faulted rafts of Early Cretaceous and Late Tertiary bedrock, a prominent organic raft, Quaternary glacial sediments, and buried glacial ice. Three distinct structural domains can be identified within the stratigraphic sequence that represent proximal to distal deformation in an ice-marginal setting. Complex thrust sequences, interfering fold-sets, brecciated bedrock and widespread shear structures superimposed on this ice-marginally deformed sequence record subsequent deformation in a subglacial shear zone. Analysis of cross-cutting relationships within the stratigraphic sequence combined with OSL dating indicate that the Worth Point hill-hole pair was deformed during two separate glaciotectonic events. Firstly, ice sheet advance constructed the hill-hole pair and glaciotectonized the strata ice-marginally, producing a proximal to distal deformation sequence. A glacioisostatically forced marine transgression resulted in extensive reworking of the strata and the deposition of a glaciomarine diamict. A readvance during this initial stage redeformed the strata in a subglacial shear zone, overprinting complex deformation structures and depositing a glaciotectonite ˜20 m thick. Outwash channels that incise the subglacially deformed strata record a deglacial marine regression, whereas aggradation of glaciofluvial sand and gravel infilling the channels record a subsequent marine transgression. Secondly, a later, largely non-erosive ice margin overrode Worth Point, deforming only the most surficial units in the section and depositing a

    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.

    2014-01-01

    The Baltic Sea is susceptible to pollution by hazardous substances due to limited water exchange, shallowness, and the large catchment area. Radionuclides, particularly 137 Cs, are one of the most hazardous anthropogenic substances present in the Baltic environment. This study was conducted to present 137 Cs present contamination that should further be a subject of reliable monitoring when the new Nuclear Power Plant is put into operation in the northern Poland. The sea-wide, up to date distribution of 137 Cs activities and inventories in the Baltic Sea bottom sediments are presented. The 137 Cs activity concentrations were measured in 30 cm long sediment cores collected at 22 sampling stations. Sediment accumulation rates were quantified by 210 Pb geochronology to follow the history of 137 Cs accumulation. The 137 Cs inventories and fluxes were calculated. Most of the Baltic Sea sediments accumulated 137 Cs in the range from 750 to 2675 Bq m −2 . The Bothnian Bay is severely contaminated by 137 Cs with inventories up to 95,191 Bq m −2 . This region is moreover characterized by extremely large patchiness of 137 Cs inventories. The 137 Cs annual fluxes are highest at the two stations located at the Bothnian Bay (342 Bq m −2 and 527 Bq m −2 ) due to large Chernobyl 137 Cs contamination of that region and high sediment accumulation rates. When these stations are excluded, the recent, annual mean value of 137 Cs load to the Baltic Sea deposits is 38 ± 22 Bq m −2 . The distribution of radio-caesium inventories over the Baltic Sea nowadays reflects the pattern of Chernobyl contamination. The radio-caesium deposited in surface sediments is not permanently buried, but may be resuspended and redeposited by currents, bioturbation or anthropogenic activities. -- Highlights: • 137 Cs contamination in the Baltic Sea was studied before the new NPP is put into operation. • Bothnian Sea sediments are severely contaminated by 137 Cs (inventories up to 95,191 Bq m

  12. Comparison of several climate indices as inputs in modelling of the Baltic Sea runoff

    Using Transfer function (TF) models, we have earlier presented a chain of events between changes in the North Atlantic Oscillation (NAO) and their oceanographical and ecological consequences in the Baltic Sea. Here we tested whether other climate indices as inputs would improve TF models, and our understanding of the Baltic Sea ecosystem. Besides NAO, the predictors were the Arctic Oscillation (AO), sea-level air pressures at Iceland (SLP), and wind speeds at Hoburg (Gotland). All indices produced good TF models when the total riverine runoff to the Baltic Sea was used as a modelling basis. AO was not applicable in all study areas, showing a delay of about half a year between climate and runoff events, connected with freezing and melting time of ice and snow in the northern catchment area of the Baltic Sea. NAO appeared to be most useful modelling tool as its area of applicability was the widest of the tested indices, and the time lag between climate and runoff events was the shortest. SLP and Hoburg wind speeds showed largely same results as NAO, but with smaller areal applicability. Thus AO and NAO were both mostly contributing to the general understanding of climate control of runoff events in the Baltic Sea ecosystem. (orig.)

  13. Coccolithophores and calcite saturation state in the Baltic and Black Seas

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available The Baltic and Black Seas are both brackish, that is to say both have salinities intermediate between freshwater and seawater. The coccolithophore Emiliania huxleyi is abundant in one, the Black Sea, but absent from the other, the Baltic Sea. Here we present summertime coccolithophore measurements confirming this difference, as well as data on the calcium carbonate saturation state of the Baltic Sea. We find that the Baltic Sea becomes undersaturated (or nearly so in winter, with respect to both the aragonite and calcite mineral forms of CaCO3. Data for the Black Sea are more limited, but it appears to remain strongly supersaturated year-round. The absence of E. huxleyi from the Baltic Sea could therefore potentially be explained by dissolution of their coccoliths in winter, suggesting that minimum annual (wintertime saturation states could be most important in determining future ocean acidification impacts. In addition to this potential importance of winter saturation state, alternative explanations are also possible, either related to differences in salinity or else to differences in silicate concentrations.

  14. Atmospheric deposition of nitrogen to the Baltic Sea in the period 1995–2006

    Directory of Open Access Journals (Sweden)

    J. Bartnicki

    2011-10-01

    Full Text Available The EMEP/MSC-W model has been used to compute atmospheric nitrogen deposition into the Baltic Sea basin for the period of 12 yr: 1995–2006. The level of annual total nitrogen deposition into the Baltic Sea basin has changed from 230 Gg N in 1995 to 199 Gg N in 2006, decreasing 13 %. This value corresponds well with the total nitrogen emission reduction (11 % in the HELCOM Contracting Parties. However, inter-annual variability of nitrogen deposition to the Baltic Sea basin is relatively large, ranging from −13 % to +17 % of the averaged value. It is mainly caused by the changing meteorological conditions and especially precipitation in the considered period. The calculated monthly deposition pattern is similar for most of the years showing maxima in the autumn months October and November. The source allocation budget for atmospheric nitrogen deposition to the Baltic Sea basin was calculated for each year of the period 1997–2006. The main emission sources contributing to total nitrogen deposition are: Germany 18–22 %, Poland 11–13 % and Denmark 8–11 %. There is also a significant contribution from distant sources like the United Kingdom 6–9 %, as well as from the international ship traffic on the Baltic Sea 4–5 %.

    The concentrations of heavy metals (Cd, Cu, Ni, Pb, Zn and Mn) and macroelements (K, Na, Ca and Mg) were determined in green alga Enteromorpha sp. from the coastal zone of the southern Baltic including Gulf of Gdansk and Vistula Lagoon in 2000-2003. In order to estimate the degree of accumulation of each element by the green alga, concentration and discrimination factors (CFs) with respect to seawater were calculated. The results of factor analysis (FA) and ANOVA clearly indicate geographical differences between concentrations of chemical elements. Enteromorpha sp. from Vistula Lagoon and the southern Baltic exhibited higher levels of Mn and Ni, and Na and K, respectively. Anthropogenic impact of Cu, Pb and Zn, possibly originated from municipal sewage, was identified in alga samples collected in the Gulf of Gdansk, especially in the vicinity of Gdynia. From comparison our data with those published earlier results that Pb content in Enteromorpha sp. from the Gulf of Gdansk decreased within 1978-2003 reflecting reducing use of leaded petrol in Baltic countries in this period. The alga Enteromorpha sp. can be used for biomonitoring surveys of metal contaminants in coastal areas of the Baltic Sea. - Enteromorpha sp. can be used as efficient biomonitor for chemical elements in coastal areas of the Baltic Sea

  17. Estimating the effective nitrogen import: An example for the North Sea-Baltic Sea boundary

    Radtke, H.; Maar, M.

    2016-10-01

    Semienclosed water bodies such as the Baltic Sea are prone to eutrophication problems. If local nutrient abatement measures are taken to tackle these problems, their success may be limited if a strong nutrient exchange with the adjacent waters exists. The quantification of this exchange is therefore essential to estimate its impact on the ecosystem status. At the example of the Baltic Sea and the North Sea, we illustrate that neither gross transports nor net transports of nutrients have a strong informative value in this context. Instead, we define an "effective import" as the import of nutrients which have not been inside the Baltic Sea before and estimate it in an ecological model with a nutrient-tagging technique. This effective import of bioreactive nitrogen from the Skagerrak to the Kattegat amounts to 103 kt/yr; from Kattegat to Belt Sea it is 54 kt/yr. The nitrogen exchange is therefore 30% stronger than other estimates, e.g., based on import in the deep water, suggest. An isolated view on the Baltic Sea and the North Sea in terms of eutrophication, as it is practiced in management today, is therefore questionable. Nitrogen imported from the North Sea typically spreads eastward up to the Bornholm Basin but can be transported into the deep waters of the Gotland Basin during Major Baltic Inflows in a significant amount.

  18. Baltic Pathways from Liberal Trade Model to Neo-Mercantilism in the European Union

    2015-09-01

    Full Text Available The economic progress of the Baltic States after the restoration of independence has been closely related to the liberal ideology and values of their economies: openness to investments, simple tax system and low tax burden, liberal trade policy, and flexible labour market. Unlike the Baltic States, some of their main partners in the European Union (EU have focused on promoting their economic growth by the neo-mercantilist way of expanding exports, supported by the economic structure of these countries exporting high technology and capital goods. As a result, when the Baltic States are expecting that in a broader context the other eu member states share the same vision of the liberal market economy, their motives have not been fully understood among their regional trade and cooperation partners. Current study will debate whether the practical implementation and needs of the European neo-mercantilism meet the economic and social needs of the Baltic States. Additionally, the study focuses on the question whether in practice the Baltic countries should be ready for the European neo-mercantilist project in upcoming years.

    Full Text Available Entrepreneurship is by far the most important force stimulating economic growth and social progress. In case of the Baltic States pro-market regulation allowed passing over the transition period in a relatively short period of time and, therefore, be sufficiently competitive as to integrate into the European Union. Thus, presently, the Baltic States came to be the most economically developed countries among the former USSR states. Consequently, the present research addresses three key questions, first, which is the role of entrepreneurship in determining the Baltic States’ economic development, second, what is the influence of R&D investments of the society in general and of business in particular in boosting economic development, and third, will the present fiscal policies in the Baltic States motivate further economic growth by stimulating entrepreneurial and innovation? The methodology involved in this paper includes both quantitative and qualitative indicators which combined will offer a deeper insight upon the matter of the present research. The results received allowed reaching the conclusion that entrepreneurship has enhanced all the Baltic States’ economic competitiveness yet the extent differ, with Estonia leading followed by Lithuania and Latvia.

  3. Stratigraphic condensation of marine transgressive records: Origin of major shell deposits in the Miocene of Maryland

    Energy Technology Data Exchange (ETDEWEB)

    Kidwell, S.M. (Univ. of Chicago, IL (USA))

    1989-01-01

    Cyclic stratigraphic sequences in shallow marine records are commonly charaterized by a condensed transgressive lag at the base of thicker, shallowing-upward facies. The standard actualistic model for these thin fossiliferous lags, by which most of the shelf is starved owing to coastal trapping of sediment and fossils are suspected of being reworked because of the association with an erosional ravinement, is contradicted by detailed stratigraphic and taphonomic analysis of Miocene examples in the Maryland coastal plain. The complex internal stratigraphies of the shell deposits and the mixture of soft- and shell-bottom faunas indicate condensation under a regime of dynamic bypassing rather than complete sediment starvation; bypassed fine sediments accumulated in deeper water environments below storm wavebase. Deeper, even more basinward parts of the shelf were starved of all sediment size fractions and accumulated shell-poor, bone-rich condensed deposits that lie mid-cycle (bracketing the time of maximum water depth). The base-of-cycle shell deposits and mid-cycle bone bed differ not only in composition and in environment and dynamics of condensation, but also in chronostratigraphic value: the onlapping shell deposits must be diachronous to some degree, whereas the mid-cycle bone bed approximates an isochronous marker for correlation. Thus, in some settings at least, transgressive shelves present a spatial mosaic of condensational and depositional regimes. Regardless of origin, all condensed intervals can time-average assemblages and telescope biostratigraphic datums. They otherwise differ widely, however, in paleontologic attributes and are characterized by highly variable and complex stratigraphic anatomies.

  4. Morphodynamics and stratigraphic architecture of shelf-edge deltas subject to constant vs. dynamic environmental forcings

    Science.gov (United States)

    Straub, K. M.

    2017-12-01

    When deltas dock at the edge of continental margins they generally construct thick stratigraphic intervals and activate channelized continental slope systems. Deposits of shelf-edge deltas have the capacity to store detailed paleo-environmental records, given their location in the source to sink system. However, present day highstand sea-level conditions have pushed most deltaic systems well inbound of their shelf-edges, making it difficult to study their space-time dynamics and resulting stratigraphic products. Several competing theories describe how deltas and their downslope environments respond to sea-level cycles of varying magnitude and periodicity. We explore these hypotheses in a physical experiment where the topographic evolution of a coupled delta and downdip slope system was monitored at high temporal and spatial resolution. The experiment had three stages. In the first stage a delta aggraded at the shelf-edge under constant water and sediment supply, in addition to a constant generation of accommodation through a sea-level rise. In the second stage the sediment transport system responded to low magnitude and high frequency sea-level cycles. Finally, in the third stage the transport system responded to a high magnitude and long period sea-level cycle. In each stage, fine sediment from the input grain size distribution and dissolved salt in the input water supply promoted plunging hyperpycnal flows. Specifically, we compare the mean and temporal variability of the sediment delivered to the slope system between stages. In addition, we compare stratigraphic architecture and sediment sizes delivered to the slope system in each stage. These results are used to improve inversion of slope deposits for paleo-environmental forcings.

  5. Tectonic evolution of the Paranoá basin: New evidence from gravimetric and stratigraphic data

    Science.gov (United States)

    Martins-Ferreira, Marco Antonio Caçador; Campos, José Eloi Guimarães; Von Huelsen, Monica Giannoccaro

    2018-06-01

    Field gravimetric and stratigraphic surveys were conducted with the aim to constraint the mechanisms responsible for the initiation of the Stenian-Tonian Paranoá basin, central Brazil, a subject not yet studied in detail. The Paranoá Group crops out in the external zone of the Brasília Belt, a Neoproterozoic orogen in the western margin of the São Francisco Craton. Detailed geological mapping confirmed the existence of a regional scale fault that controlled sedimentation of the Paranoá Group during the deposition of its basal formations, revealing important details about basin initiation and early evolution. Gravimetric modeling indicates the existence of paleorift structures beneath the Paranoá sequence in the study area. Results from both stratigraphic and gravimetric surveys show strong evidence of mechanical subsidence by faulting during basin initiation. Unsorted, angular, clasts cut by quartz veins and brecciated boulders present in the basal conglomerate, support this hypothesis. Basin initiation faults coincide with deeper paleorift faults and are thus interpreted as reactivations of the older Statherian Araí Rift. The reactivations favored an initial regime of mechanical subsidence, dominated by the development of epirogenic arches subsiding at different rates. Apart from faulting activity, the post-basal sequence presents no evidence of rift environment in the strict sense. Besides, the great lateral continuity and relatively constant thickness of facies, indicate that an initial mechanic subsidence rapidly gave way to flexural subsidence during subsequent stages of basin evolution. The Paranoá Group do not present reliable characteristics that would allow its strict classification as a passive margin. Its main stratigraphic characteristics, tectonic location and basement architecture, indicate that the Paranoá Group was deposited in a cratonic margin basin, and may have been either connected to a passive margin basin at times of sea level rise

    1994-01-01

    Stratigraphic and geomorphic relations, archaeological data, and eight radiocarbon ages at five widely scattered localities in northeastern Colorado indicate that eolian sand was mobilized over broad areas within the past 1000 yr. The mobilization began after 1 ka, was episodic, and ended at some as yet undetermined time prior to the latter part of the 19th century. Given that climate-model simulations suggest only slight variation in average surface temperature and annual precipitation in this region during the past 1000 yr, this part of the Great Plains evidently is near the threshold of widespread eolian sand transport under the present climate. -Author

    During April and May, 1991, the U.S. Geological Survey (USGS) drilled a 510-ft-deep, continuously cored, stratigraphic test hole on Horn Island, Mississippi Sound, as part of a field study of the Neogene and Quaternary geology of the Mississippi coastal area. The USGS drilled two new holes at the Horn Island site. The first hole was continuously cored to a depth of 510 ft; coring stopped at this depth due to mechanical problems. To facilitate geophysical logging, an unsampled second hole was drilled to a depth of 519 ft at the same location.

  8. The stratigraphic distribution of large marine vertebrates and shell beds in the Pliocene of Tuscany

    2015-04-01

    The record of 337 shark fossils, 142 cetaceans and 10 sea cows from the Pliocene of Tuscany, mostly from historical museum collections, is revised. The majority of these fossils are concentrated at a few geographic sites from separated hinterland basins, on the South-Western side of the Northern Apennines. To better understand the meaning of these concentrations, the sequence stratigraphic distribution of more recent findings of large marine vertebrates is reconstructed against a high-resolution framework based on sedimentary facies analysis. These remains are usually covered by, or included in mudstones deposited far from the coast (N=12), skeletons being usually articulated, slightly displaced, and often bioeroded. A minor part of better preserved articulated skeletons is associated with sandstones from deltaic paleonenvironments (N=2). Marine mammal and shark remains may be associated with laterally-continuous shell accumulations, a type of concentration occurring at maximum flooding surfaces, separating relatively coarse-grained facies from open marine mudstones. Shell beds were bulk-sampled at 66 locations from six basins, covering a wide range of sedimentary facies, and spanning a chronologic interval of about 2.5 million years. A dataset of 62,655 mollusc specimens belonging to 496 species formed the basis of a statistical study to reconstruct the structure of the benthic communities, and to estimate paleodepths from intertidal to upper bathyal settings. Mollusc associations closely mirror the distribution of sedimentary facies, allowing for a fine tuning of the sequence stratigraphic architecture. Merging paleogeographic, stratigraphic and paleoecologic data, we conclude that the more abundant and diverse accumulations of large vertebrates took place in settings under the influence of coastal upwelling. A modern analogue occurs today in the Ligurian Sea, on the Tuscan offshore, where abundant nutrients carried by deep-marine currents of Western origin

    Integration between seismic and geological data is crucial to ensure that a reservoir study is accurate and reliable. To reach this goal, there is used a post-stack stratigraphic inversion with a priori information. The global cost-function combines two types of constraints. One is relevant to seismic amplitudes, and the other to an a priori impedance model. This paper presents this flexible and interpretative inversion to determine acoustic impedances constrained by seismic data, log data and geologic information. 5 refs., 8 figs.

To pursue an independent agenda and increase their significance within large associa­tions, the authors argue, small powers tend to create ‘coalitions within coalitions’, essentially acting as free riders and transferring costs and political responsibility for decision-making to larger players. Such an asymmetric strategy makes it possi­ble for small powers to advance their interests within alliances and save resources. The authors test this hypothesis on the behaviour of the Baltics in the European Union. It is demonstrated that Lithuania, Latvia, and Estonia have created a stable small coalition within the EU and actively form ad hoc alliances with the leading states to push union-level decisions, as it was the case with settling the migrant issue. In other areas, these states tend to benefit from the free rider behaviour.

  12. Economic crisis in the Baltic states : Focusing on Latvia

    2010-01-01

    Full Text Available This paper examines the causes of the economic crisis in new EU member states in Central and Eastern Europe, focusing on the Baltic States, especially Latvia. Thanks to the Single Market of the EU, workers in this country became able to migrate to advanced EU countries, especially the UK, decreasing the unemployment rate and at the same time causing a sharp increase in wages due to a tightened labour market. Banks from Nordic countries came to operate in Latvia and competed for market shares, stirring a consumption boom. In a situation in which people can easily get loans denominated in a foreign currency the monetary policies of the central bank are weakened. The Latvian economy already showed signs of overheating in 2005. However in the spring of 2007 the government turned to restrictive policies, causing a depression at the end of 2007. The Lehman shock dealt the Latvian economy its final blow. Latvia set up the introduction of the Euro in 2013 as an exit strategy. Latvia is in a dilemma: if the country does not devalue its national currency and tries to satisfy the Maastricht criteria soon, it will be obliged to adopt pro-cyclical policies, causing economic stagnation.

  13. Outdoor model simulating a Baltic Sea littoral ecosystem

    Plastic pools (surface 6.6 m/sup 2/, volume 4.2 m/sup 3/) were equipped with a flow-through system providing 2.51 min/sup -1/. Except for fish predators the main components of the flora and fauna of the Baltic littoral zone were introduced into the pools to form a model of the ecosystem. During 8 weeks the macroscopic epifauna and infauna of the bladder wrack Fucus vesiculosus L. were found to be qualitatively and quantitatively fairly stable, and the number of aerobic heterotrophic bacteria showed little variation. Oxygen concentration, temperature and pH were recorded and compared with values measured in the littoral zone. The results indicate good agreement between the characters of the model system and of the natural littoral ecosystem. This together with the observed stability and the possibilities for controlling and measuring the conditions in the system makes us believe that the model is a valuable tool for assessing toxic effects on the littoral ecosystem.

  14. Baltic Herring Fisheries Management: Stakeholder Views to Frame the Problem

    Full Text Available Comprehensive problem framing that includes different perspectives is essential for holistic understanding of complex problems and as the first step in building models. We involved five stakeholders to frame the management problem of the Central Baltic herring fishery. By using the Bayesian belief networks (BBNs approach, the views of the stakeholders were built into graphical influence diagrams representing variables and their dependencies. The views of the scientists involved concentrated on biological concerns, whereas the fisher, the manager, and the representative of an environmental nongovernmental organization included markets and fishing industry influences. Management measures were considered to have a relatively small impact on the development of the herring stock; their impact on socioeconomic objectives was greater. Overall, the framings by these stakeholders propose a focus on socioeconomic issues in research and management and explicitly define management objectives, not only in biological but also in social and economic terms. We find the approach an illustrative tool to structure complex issues systematically. Such a tool can be used as a forum for discussion and for decision support that explicitly includes the views of different stakeholder groups. It enables the examination of social and biological factors in one framework and facilitates bridging the gap between social and natural sciences. A benefit of the BBN approach is that the graphical model structures can be transformed into a quantitative form by inserting probabilistic information.

  15. Perspectives on Retail Service Quality: Findings From the Baltic States

    Full Text Available Service quality research continues to represent one of the major tenets of Services Marketing, but there continues to be limited research in the field outside of Developed, Western markets.  In order to advance the knowledge of service quality in non-western markets, the focus of this paper is to examine one particular field of service quality research, retail service quality, in the former Soviet Republics of Estonia, Latvia, and Lithuania.The testing of a model of retail service quality, using empirical survey data collected in these three recent members of the European Union, indicate support that the retail service quality construct both aligns and differs, across the three countries.The implication of these similarities and differences are important from two perspectives.  The first is the appropriateness of extending Western developed marketing scales and measures within newly emerging, and catching up states.The second implication, which is important to retail practice, questions the position of treating these three countries, known collectively as the Baltic states as a homogenous market.  Additional implications to retail practice and future academic research studies are also discussed.

    Although seagrasses cover only a minor fraction of the ocean seafloor, their carbon sink capacity accounts for nearly one-fifth of the total oceanic carbon burial and thus play a critical structural and functional role in many coastal ecosystems. We sampled 10 eelgrass (Zostera marina) meadows....... The C-org stock integrated over the top 25 cm of the sediment averaged 627 g C m(-2) in Finland, while in Denmark the average C-org stock was over 6 times higher (4324 g Cm-2).

  17. Perspectives for RandD in Bioenergy in the Baltic States

    Energy Technology Data Exchange (ETDEWEB)

    Holmberg, Rurik (Technopolis Group, Stockholm (Sweden) )

    2009-11-15

    This study has identified two almost contradictory trends regarding bioenergy in the Baltic States. On the one hand, RandD performed in bioenergy in the Baltic States is rather limited. This might be somewhat surprising, because on the other hand various forms of bioenergy are either already used on a large scale or are widely assumed to become important in the near future. Bioenergy is explicitly recognized in various policy plans as an important component of the energy system in all the Baltic States. Thus the limited RandD efforts raise a number of questions, which probably lack unequivocal answers, but which would be important to discuss in the Baltic States. In all three Baltic States, bioenergy has a major potential. The present trend with boiler houses using biomass in a district heating systems commenced in the 1990s with significant foreign support. Technology was mainly imported, but in some cases local producers have drawn upon these experiences and become producers in their own right. The result has been that the Baltic States have relatively well developed bioenergy technology in use in district heating. But perhaps more importantly, there is know-how and experience in the Baltic States from the use of bioenergy, which however needs to be constantly upgraded. Regarding interest groups, one question raised by some interviewees was whether the natural gas industry with Russian Gazprom as the key player has a bigger say in the energy policy of the Baltic States than officially admitted. Although this issue remains speculative, the question as such is justified and should not be omitted from the discussion. The interest groups behind bioenergy are relatively weak, at least in comparison with other interest groups in the energy sector. As long as the farmers' organizations are not unambiguously behind bioenergy, the political support for investments in developing new technology is likely to remain lukewarm.

  18. A three-dimensional stratigraphic model for aggrading submarine channels based on laboratory experiments, numerical modeling, and sediment cores

    Turbidity currents deliver clastic sediment from continental margins to the deep ocean, and are the main driver of landscape and stratigraphic evolution in many low-relief, submarine environments. The sedimentary architecture of turbidites—including the spatial organization of coarse and fine sediments—is closely related to the aggradation, scour, and lateral shifting of channels. Seismic stratigraphy indicates that submarine, meandering channels often aggrade rapidly relative to lateral shifting, and develop channel sand bodies with high vertical connectivity. In comparison, the stratigraphic architecture developed by submarine, braided is relatively uncertain. We present a new stratigraphic model for submarine braided channels that integrates predictions from laboratory experiments and flow modeling with constraints from sediment cores. In the laboratory experiments, a saline density current developed subaqueous channels in plastic sediment. The channels aggraded to form a deposit with a vertical scale of approximately five channel depths. We collected topography data during aggradation to (1) establish relative stratigraphic age, and (2) estimate the sorting patterns of a hypothetical grain size distribution. We applied a numerical flow model to each topographic surface and used modeled flow depth as a proxy for relative grain size. We then conditioned the resulting stratigraphic model to observed grain size distributions using sediment core data from the Nankai Trough, offshore Japan. Using this stratigraphic model, we establish new, quantitative predictions for the two- and three-dimensional connectivity of coarse sediment as a function of fine-sediment fraction. Using this case study as an example, we will highlight outstanding challenges in relating the evolution of low-relief landscapes to the stratigraphic record.

    The climate change impact on water resources is observed in all the Baltic States. These processes became more evident in the last decades. Although the territory of the Baltic States (Lithuania, Latvia, Estonia) is not large (175000 km2), the climatic differences are quite considerable. We performed a regionalization of the territory of the Baltic States depending on the conditions of river runoff formation which can be defined according to percentages of the river feeding sources (precipitation, snowmelt, groundwater). Long-term series of temperature (40 stations), precipitation (59 stations) and river discharge (77 stations) were used to compose ten regional series. This paper addresses: (1) variability in long-term regional series of temperature, precipitation and river discharge over a long period (1922-2007); (2) changes in regional series, comparing the periods 1991-2007 and 1931-1960 with the reference period (1961-1990), and (3) the impact of temperature and precipitation changes on regional river discharge.

  1. Uranium 234U and 238U isotopes in the southern Baltic environment

    International Nuclear Information System (INIS)

    Borylo, A.; Skwarzec, B.

    2002-01-01

    The concentration and distribution of uranium in water and sediment of selected basins of the southern Baltic Sea have been analysed. It was observed that the concentration of uranium in sediments increases with core depth. This is probably connected to diffusion processes from sediments to water through interstitial water where uranium concentration is much higher than in bottom water. The measurements of 234 U/ 238 U activity ratios indicate that sedimentation of terrigenic material and transport through Vistula river are the major sources of uranium in sediments of the southern Baltic Sea. Estimation of the 234 U/ 238 U ratios in reduction areas of the Baltic Deep and the Bornholm Deep suggest that the processes of reduction of U(VI) to U(IV) and of removal of authogenic uranium from seawater to sediments do not play major roles in the Gdansk Deep.

    Full Text Available An algorithm for computing ice drift from pairs of synthetic aperture radar (SAR images covering a common area has been developed at FMI. The algorithm has been developed based on the C-band SAR data over the Baltic Sea. It is based on phase correlation in two scales (coarse and fine with some additional constraints. The algorithm has been running operationally in the Baltic Sea from the beginning of 2011, using Radarsat-1 ScanSAR wide mode and Envisat ASAR wide swath mode data. The resulting ice drift fields are publicly available as part of the MyOcean EC project. The SAR-based ice drift vectors have been compared to the drift vectors from drifter buoys in the Baltic Sea during the first operational season, and also these validation results are shown in this paper. Also some navigationally useful sea ice quantities, which can be derived from ice drift vector fields, are presented.

  3. Transport interests and environmental regimes. The Baltic Sea transit of Russian oil exports

    International Nuclear Information System (INIS)

    Knudsen, Olav F.

    2010-01-01

    In the environmentally exposed Baltic Sea, a prolonged confrontation has set the transport interests of Russian crude oil against environmental interests, promoted by Russia's neighbours. During the 1990s all the Baltic littoral states - including Russia - collaborated well on marine environmental issues. When Russian oil exports accelerated after 1999, this environmental understanding broke down. Russian interests shifted as its oil income suddenly rose drastically. The confrontation peaked over a proposal to make the entire Baltic Sea into a particularly sensitive sea area (PSSA) under the International Maritime Organization (IMO). The proposal was adopted by the IMO in spite of Russian objections. The article shows how environmental interests trump transport interests in a manner that may not be sustainable. The case illustrates the need for environmental collaboration to be flexible in the face of shifting constellations of competing interests. (author)

    2006-07-01

    This report serves to document contract deliverables considered to be of continuing interest associated with two workshops conducted as part of an initial assessment of Material Protection, Control, and Accounting (MPC&A) training needs of the Newly Independent and Baltic States (NIS/Baltics). These workshops were held in Kiev, Ukraine, ca. 2003-2004, with the assistance of personnel from the George Kuzmycz Training Center (GKTC) of the Kiev Institute of Nuclear Research (KINR). Because of the dominant role Ukraine plays in the region in terms of the nuclear industry, one workshop focused exclusively on Ukrainian training needs, with participants attending from twelve Ukrainian organizations (plus U.S. DOE/NNSA representatives). The second workshop included participation by a further ten countries from the NIS/Baltics region. In addition, the training needs data developed during the workshop were supplemented by the outcomes of surveys and studies conducted by the GKTC.

    2018-03-01

    Climate change is threating species' persistence worldwide. To predict species responses to climate change we need information not just on their environmental tolerance but also on its adaptive potential. We tested how the foundation species of rocky littoral habitats, Fucus vesiculosus, responds to combined hyposalinity and warming projected to the Baltic Sea by 2070-2099. We quantified responses of replicated populations originating from the entrance, central, and marginal Baltic regions. Using replicated individuals, we tested for the presence of within-population tolerance variation. Future conditions hampered growth and survival of the central and marginal populations whereas the entrance populations fared well. Further, both the among- and within-population variation in responses to climate change indicated existence of genetic variation in tolerance. Such standing genetic variation provides the raw material necessary for adaptation to a changing environment, which may eventually ensure the persistence of the species in the inner Baltic Sea.

  7. Power sector development in a common Baltic electricity market. Executive summary

    International Nuclear Information System (INIS)

    2005-05-01

    In the years to come the Baltic electricity sector is expected to go through major changes. up till recently the sector has been characterised by vertically integrated monopolies, but at present the electricity sectors in the Baltic States are undergoing reform processes to meet the requirements of the EU directives regarding liberalisation of electricity sectors. This implies a different organisation of the sector, with new roles and responsibilities, and focus on new issues such as a well-functioning electricity market, security of supply and market power. In this project long-term scenario analyses are used to clarify the challenges facing the future Baltic electricity market and to analyse the robustness of the power sector. The project examines how existing power plants will manage in a competitive market, how power prices will develop and which investments are likely to be preferred by investors, among other issues.

    Full Text Available AbstractThis article aims to determine and analyse the main features of channels of financial contagion in the banking sector of Baltic States. The most relevant channels seem to be the risk of common lender, the channel of real estate prices the channel of other macroeconomic shocks and the channel of volatility. This paper contributes to the further analysis of internal and external causes of financial crisis and its transmission channels in banking sector in Baltic States.Purpose To indicate and explain main problems related to the systemic risk and the channels of financial contagion in the banking sector of Baltic States.Design/methodology/approach – general overview of research papers presenting concepts and methodologies of assessment of systemic risk of the banking sector, statistical analysis of financial data.Findings determination of the main channels and extent of financial contagion that are relevant to banking sector of Baltic States.Research limitations/implications – the lack of information concerning the liquidity and asset structure of banking sector of Baltic States and the real estate prices in Baltic States. The most common problem analysing the financial contagion and systemic risk is the lack of information (especially about the structure of liabilities and assets of financial institutions, its maturity and the changing new banking regulatory conditions. Due the lack of data it is impossible to create stable and reliable statistical models describing the stochastic behaviour of financial contagion. We do not take into account the political factors concerning the reforms of financial market supervision that have also the impact on financial contagion and systemic risk ant the point of view to Baltic States of foreign investors. The findings of this article should ground the macro-prudential policy in the small countries of supervising institutions focussing on the external factors.Practical implications

    2016-01-01

    Full Text Available Energy security is one of the most important indicators of sustainable regional development and 'green' growth in implementation of EU strategy Europe 2020. It can provide the harmonized development and cohesion of 'old' and 'new' EU member states. Our paper conducts a comparative study of energy dependency and energy security indicators in the Baltic States. The Baltic countries achieved enormous progress in the use of renewable energy sources and energy efficiency since their EU accession in 2004. The increase of renewable energy capacities in Baltic States also contributed to the reduction of energy intensity and carbon intensity of economy and energy import dependency. Our results show that amongst all three states, it was Estonia that had achieved the best results in increased use of renewables and energy efficiency improvements and had distinguished itself with the best indicators and economic and regional policy outcomes.

  11. Caesium-137 distribution, inventories and accumulation history in the Baltic Sea sediments.

    2014-01-01

    The Baltic Sea is susceptible to pollution by hazardous substances due to limited water exchange, shallowness, and the large catchment area. Radionuclides, particularly (137)Cs, are one of the most hazardous anthropogenic substances present in the Baltic environment. This study was conducted to present (137)Cs present contamination that should further be a subject of reliable monitoring when the new Nuclear Power Plant is put into operation in the northern Poland. The sea-wide, up to date distribution of (137)Cs activities and inventories in the Baltic Sea bottom sediments are presented. The (137)Cs activity concentrations were measured in 30 cm long sediment cores collected at 22 sampling stations. Sediment accumulation rates were quantified by (210)Pb geochronology to follow the history of (137)Cs accumulation. The (137)Cs inventories and fluxes were calculated. Most of the Baltic Sea sediments accumulated (137)Cs in the range from 750 to 2675 Bq m(-2). The Bothnian Bay is severely contaminated by (137)Cs with inventories up to 95,191 Bq m(-2). This region is moreover characterized by extremely large patchiness of (137)Cs inventories. The (137)Cs annual fluxes are highest at the two stations located at the Bothnian Bay (342 Bq m(-2) and 527 Bq m(-2)) due to large Chernobyl (137)Cs contamination of that region and high sediment accumulation rates. When these stations are excluded, the recent, annual mean value of (137)Cs load to the Baltic Sea deposits is 38 ± 22 Bq m(-2). The distribution of radio-caesium inventories over the Baltic Sea nowadays reflects the pattern of Chernobyl contamination. The radio-caesium deposited in surface sediments is not permanently buried, but may be resuspended and redeposited by currents, bioturbation or anthropogenic activities.

  12. Cost effective reductions in the agricultural load of nitrogen to the Baltic Sea

    Energy Technology Data Exchange (ETDEWEB)

    Elofsson, K.

    1997-11-01

    To restore the health of the Baltic Sea, the Helsinki Commission, HELCOM, suggests that the nitrogen load should be reduced by 50%. The agricultural sector accounts for about 1/3 of the total load of nitrogen to the Baltic Sea, while point sources account for about 1/4. The remaining load reaches the Baltic as atmospheric deposition. The purpose of this study is to calculate cost effective reductions in the agricultural load of nitrogen to the Baltic Sea coastal waters. The Baltic Sea drainage basin is divided into 17 regions, which differ with respect to costs, leaching and nitrogen retention. For each region, cost functions are estimated for 11 nitrogen abatement measures in the agricultural sector. It is difficult to find reliable data on both costs and biological parameters for all regions included, and several assumptions are made to obtain the cost functions. In this paper the total cost of a 50% reduction of the nitrogen load from arable land is estimated to 11,700 million SEK per year. A decrease in the use of fertilizer nitrogen is the most important measure in a cost effective policy. Other measures included in the cost effective solution are changes in land-use and in manure management practices. If, instead, each country is required to reduce its load by 50%, the total cost will increase by nearly 60%. Three out of nine countries around the Baltic Sea would gain from separate reduction targets, while all others lose by such a policy. The results are sensitive to assumptions about the biological parameters and the shape of the cost functions for reductions in chemical fertilizer. 75 refs, 3 figs, 11 tabs

  13. Historic changes in length distributions of three Baltic cod (Gadus morhua) stocks: Evidence of growth retardation.

    Svedäng, Henrik; Hornborg, Sara

    2017-08-01

    Understanding how combinations of fishing effort and selectivity affect productivity is central to fisheries research. We investigate the roles of fishing regulation in comparison with ecosystem status for Baltic Sea cod stock productivity, growth performance, and population stability. This case study is interesting because three cod populations with different exploitation patterns and stock status are located in three adjacent but partially, ecologically different areas. In assessing stock status, growth, and productivity, we use survey information and rather basic stock parameters without relying on age readings. Because there is an urgent interest of better understanding of the current development of the Eastern Baltic cod stock, we argue that our approach represents partly a novel way of interpreting monitoring information together with catch data in a simplified yet more informative way. Our study reports how the Eastern and Western Baltic cod have gone toward more truncated size structures between 1991 and 2016, in particular for the Eastern Baltic cod, whereas the Öresund cod show no trend. We suggest that selective fishing may disrupt fish population dynamic stability and that lower natural productivity might amplify the effects of selective fishing. In support of earlier findings on a density-dependent growth of Eastern Baltic cod, management is advised to acknowledge that sustainable exploitation levels for Eastern Baltic cod are much more limited than perceived in regular assessments. Of more general importance, our results emphasize the need to embrace a more realistic view on what ecosystems can produce regarding tractable fish biomass to facilitate a more ecosystem-based fisheries management.

  14. American Foreign Policy Think Tanks and their Views on Baltic Security

    2017-12-01

    Full Text Available Recent events have created a sense of urgency within the U.S. foreign policy establishment to update its strategy towards Russia. The Baltic states are seen to be particularly vulnerable and because of its NATO commitments and its history of underwriting security in the region, the U.S. is under pressure to develop an appropriate response. Policy and research institutes-or think tanks-are an important part of the U.S. foreign policy establishment, and given the influence they often have on American foreign policy, it is sensible for any student of Baltic security to evaluate the think tanks’ current perspectives on the viability and desirability of U.S. security commitments in the region. To that end, this article evaluates the outputs of twelve prominent U.S. foreign policy think tanks according to the views they expressed across four general groupings of issues: positions on U.S. grand strategy, perceptions of Moscow’s intentions and capabilities, assessments of NATO’s heath and its value to U.S. security, and the level of commitment to, and assessment of, the security vulnerabilities of the Baltic states. The findings dispel a common misperception that U.S. foreign policy think tanks are generally shifting towards a realist perspective on the Baltic states; they generally do not support U.S. retrenchment, most consider Russia as having revanchist motives, and as a whole support bolstering the defences of NATO’s easternmost flank. However, it would also be an exaggeration to conclude that the U.S. think tank community overall were staunch defenders of the Baltic states, as for many there is a prevailing inattentiveness to Baltic security issues.

  15. POP load and vitamins as potential biomarkers in the Baltic seals

    2004-09-15

    Exceptionally high levels of polychlorinated biphenyls (PCB) and 1,1,1.trichloro- 2,2-bis[p-chlorophenyl]ethane (DDT) and its metabolites were reported in the Baltic seals in the late 1960s and early 1970s. PCB levels in ringed seals, in particular, are still high enough to threaten the well being of the animals. The observed difference in contaminant pattern between ringed and grey seals in the Baltic has not been explained, but could be partly due to species-specific food sources. Several pathological and biochemical changes observed in the Baltic seals correlate with the individual POP loads. Of the observed biochemical changes, elevated cytochrome P4501A (CYP1A) levels, decreased liver vitamin A stores and increased vitamin E levels in blubber or plasma, have been proposed as possible biomarkers of contaminant load in Baltic seals. However, as the vitamin A and E status of marine mammals also reflects the nutritional vitamin level, the lower vitamin A and elevated vitamin E levels observed in the Baltic seals could be a reflection of the levels of these vitamins in their food sources. The aim of this study was to investigate the contaminant load in the Baltic seals and to evaluate the utility level of potential exposure and effect biomarkers. Seals from less contaminated areas were used as reference material (Svalbard and Sable Island, Canada). In the present study, POP and vitamin levels were also studied in seal prey species in order to study the transfer of these compounds to grey and ringed seals from their main food sources.

    Anthropogenically induced changes in precipitation are projected to generate increased river runoff to semi-enclosed seas, increasing 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 abundances than Bothnian Sea bacteria in both Baltic Proper and Bothnian Sea water, indicating higher adaptability. Moreover, Baltic Proper bacteria growing in Bothnian Sea water consistently showed highest bacterial production and beta-glucosidase activity. These metabolic responses were accompanied by basin-specific changes in bacterial community structure. For example, Baltic Proper Pseudomonas and Limnobacter populations increased markedly in relative abundance in Bothnian Sea water, indicating a replacement effect. In contrast, Roseobacter and Rheinheimera populations were stable or increased in abundance when challenged by either of the waters, indicating an adjustment effect. Transplants to Bothnian Sea water triggered the initial emergence of particular Burkholderiaceae populations, and transplants to Baltic Proper water triggered Alteromonadaceae populations. Notably, in the subsequent re-transplant experiment, a priming effect resulted in further increases to dominance of these populations. Correlated changes in community composition and metabolic activity were observed only in the transplant experiment and only at relatively high phylogenetic resolution. This suggested an importance of successional progression for interpreting relationships between bacterial community composition and functioning. We infer that priming effects on bacterial community structure by natural episodic events or climate change induced forcing could translate into long-term changes in bacterial ecosystem process rates.

    Monitoring of radioactive substances in the Baltic Sea 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 some also for 90 Sr and transuranic elements. The general levelling of Chernobyl derived 137 Cs and 134 Cs in the water mass of the Baltic Sea, which had started soon after the fallout situation, continued in 1989. The activity concentration of 137 Cs was about the same level (120-160 Bq/m 3 ) in surface water throughout the Baltic Sea area except in some coastal areas. The cesium concentrations had levelled vertically as well as horizontally. In 1990, the cesium concentrations of surface water decreased further in other sea areas, but not in the Bothnian Sea, where somewhat higher values were detected once more. In bottom sediments the total amounts of 137 Cs had clearly increased between 1988 and 1990 which indicates that fresh fallout was still settling on the bottom. No increase was found in the total amounts of 239 , 240 Pu. Small amounts of 60 Co were detected in the surface sediment of our sampling station in the Northern Baltic proper. 137 Cs concentrations in Baltic herring ranged from 17 to 32 Bq/kg fresh weight and pike from 22 to 290 Bq/kg fresh weight, the maximum values being in the samples supplied from the Vaasa archipelago. The internal radiation dose received by Finns from eating Baltic Sea fish was 0.01mSv both in 1989 and in 1990. (orig.)

    In the last two decades, great progress has been made in the geochronological, chrono- and chemostratigraphic control of the Neoproterozoic and Cambrian from the Anti-Atlas Ranges and the Ouzellagh promontory (High Atlas). As a result, the Neoproterozoic is lithostratigraphically subdivided into: (i) the Lkest-Taghdout Group (broadly interpreted at c. 800–690 Ma) representative of rift-to-passive margin conditions on the northern West African craton; (ii) the Iriri (c. 760–740 Ma), Bou Azzer (c. 762–697 Ma) and Saghro (c. 760?–610 Ma) groups, the overlying Anezi, Bou Salda, Dadès and Tiddiline formations localized in fault-grabens, and the Ouarzazate Supergroup (c. 615–548 Ma), which form a succession of volcanosedimentary complexes recording the onset of the Pan-African orogeny and its aftermath; and (iii) the Taroudant (the Ediacaran–Cambrian boundary lying in the Tifnout Member of the Adoudou Formation), Tata, Feijas Internes and Tabanite groups that have recorded development of the late Ediacaran–Cambrian Atlas Rift. Recent discussions of Moroccan strata to select new global GSSPs by the International Subcommissions on Ediacaran and Cambrian Stratigraphy have raised the stratigraphic interest in this region. A revised and updated stratigraphic framework is proposed here to assist the tasks of both subcommissions and to fuel future discussions focused on different geological aspects of the Neoproterozoic–Cambrian time span.

    The sedimentary core ranges 0-35m depth and covers three types of bituminous shales, intercalated by two layers of sterile clay. A systematic geochemical study of samples of most stratigraphic layers was undertaken for the first time in this work, including elemental analysis (C, H), carbonate content, type of organic matter, infrared spectrometry and molecular characterization of organic extracts (hight-resolution) gas chromatography, mass spectrometry). No consistent correlation between lithology and amount/type of organic matter was observed, contrary to literature data, pointing out the paper shale strata as richest in organic matter. Molecular stratigraphy of the core presented similar n-alkane profiles generally maximizing at n-C 27 attesting to a small variation in input along the sedimentary section. Characterization of the branched/cyclic hydrocarbons evidenced a continental input to the sediment, as revealed by the presence, in several layers, of isometric des-A-fernenes, presumed products of diagenesis of arborinone. A microbial input was also evidenced through the general occurrence of hopanoids, trace amounts of steroidal skeletons as well as atomic H/C ratios ca. 2. The sharp variations in biomarker profiles with depth showed great potential as correlation markers in a detailed stratigraphic study of the basin, as a valuable supplement to traditional lithological parameters.

    The stratigraphic model from the west-central Alberta basin was provided. It defined the Z Marker as a distinctive and widespread wireline log marker within the thick Frasnian Ireton shale basin succession. The marker represents an interval of condensed sedimentation and corresponds to an abrupt change from a calcareous signature below to an argillaceous character above. Toward the shelf, in the West Pembina area, the Z Marker correlates to a level within a conformable succession of nodular lime wackestones and corresponds to the base of a depositional cycle near the middle of the Lobstick member of the Nisku Formation. Further shelfward, the Z Marker continues as a well-defined log marker until the Nisku shelf margin. The stratigraphic significance of the Z Marker in delineating various oil bearing formations in Alberta were explained in great detail. The correct recognition and correlation of this marker was claimed to permit an understanding of basin evolution beyond that discernable from the existing lithostratigraphic nomenclature alone. 17 refs., 13 figs.

    Aegina Kolonna, located in the center of the Saronic Gulf in the Aegean Mediterranean (Greece), is one of the major archaeological sites of the Aegean Bronze Age with a continuous stratigraphic settlement sequence from the Late Neolithic to the Late Bronze Age. Due to its position next to the maritime cross roads between central mainland Greece, the northeast Peloponnese, the Cyclades and Crete, the island played an important role in the trade between these regions. In the course of new excavations, which focused on the exploration of the Early, Middle and Late Bronze Age at Kolonna, several short lived samples from different settlement phases have been 14 C-dated with the AMS method at the VERA laboratory. Bayesian sequencing of the 14 C data according to the stratigraphic position of the samples in the profile was performed to enable estimates of the transition time between the cultural phases. The Aegina Kolonna 14 C sequence is one of the longest existing so far for the Aegean Bronze Age, and therefore of major importance for the absolute Bronze Age chronology in this region. Preliminary results indicate that the Middle Helladic period seems to have started earlier and lasted longer than traditionally assumed. Further, at the present stage of our investigation we can give also a very tentative time frame for the Santorini volcanic eruption which seems to be in agreement with the science derived VDL date.

    Full Text Available Earthquake is one of the unpredicted natural disasters on our earth. Despite of the absence of high-accuracy method to precisely predict the occurrence of earthquake, numerous studies have been carried out by seismologists to find it. One of the efforts to address the vulnerability of a region to earthquakes is by recognizing the type of rock as the source of the earthquake. Opak Fault is an active fault which was thought to be the source of earthquakes in Yogyakarta and adjacent areas. This study aimed to determine the seismic source types of rocks in Yogyakarta and adjacent areas. The methods were by measuring stratigraphic sections and the layer thickness in the western part of Southern Mountains. Field study was done in 6 (six research sites. Results of stratigraphic measurement indicated the sedimentary rocks in the Southern Mountains was 3.823 km in thick, while the bedrock was more than 1.042 km in thick. Based on the result, the rock types as the seismic source were thought to originate from the continental crust rocks formed of granite and metamorphic complex.

    A study on the use of radiometric techniques for the identification of stratigraphic characteristics of Paraiba Basin units was carried out with handheld instrumentation. The area chosen ran from north Pernambuco to south Paraiba. The presence of radioactive material had been previously determined. For this work a portable scintillometer was fixed to the door of a vehicle, on the outside, with the probe directed downwards. Background radiation was measured as 40 cps (counts per second). The scintillometer has an alarm which sounds whenever the measured count rate rises above a pre-established figure, 100 cps in the present case. Monitoring then proceeded manually. In sites where the count rate was much higher than 100 cps, the probe was lowered to the soil surface. Local coordinates were obtained by GPS. Therefore, an isoradioactivity map of the area could be drawn. The comparison between this map and local geological charts showed significant correlation between observed count rates and geologic formations. Low count rates were indicative of the Barreiras formation, whereas the highest rates were obtained for the Gramame formation (with urano-phosphatic lythotypes). It is concluded that handheld radiometry is a useful tool in geological charting, is special in areas where stratigraphic units have been masked by environmental changes and human activities.

    Two cores of Baltic Sea sediment were collected in 1975. The 18 O/ 16 O ratio of the water enclosed in the sediment (pore water) was measured after the separation of the liquid from the solid phase. The results may support the discussion about the history of the Baltic Sea. At the top of the core the 18 O/ 16 O ratio of the water represents the oxygen isotope composition of the sea water above. Towards the deeper parts of the sediment, independently of the salt content, the 18 O/ 16 O ratio decreases towards values observed in the precipitation of the surrounding land areas. (author)

    In the Molasse foreland basin of Upper Austria gas is produced from deep-water sandstones and conglomerates of the Puchkirchen and basal Hall formations (Oligocene-Lower Miocene). The basin is mature, with >750 wells drilled by RAG to date. An extensive 3-D seismic reflection dataset that covers much of the paleo-basin foredeep has been acquired in the study area over the last 15 years. Seismic stratigraphic analysis has revealed that deepwater sedimentation in the basin was dominated by a channel belt up to 5 km wide that transported sediment derived from the Central and Eastern Alps eastward along the basin axis (Linzer, 2001; de Ruig, 2003). Based on these findings, a detailed sedimentary facies model has been developed, outlining several distinct depositional elements that reveal numerous possible stratigraphic trap types (de Ruig and Hubbard, 2006). This depositional model is currently being applied and tested in exploration and refined by ongoing research. Channel abandonment and migration are important processes that resulted in stratigraphic configurations consisting of coarse-grained sandstones and conglomerates overlain by channel and overbank mudstones. This represents ideal reservoir architecture, including porous reservoir facies sealed by impermeable deposits. Additional stratigraphic trapping conditions can result from special spatial arrangements of depositional elements, for example a sandstone-filled tributary channel that is sealed by an overlying mudstone-filled abandonment channel. Recognizing and further improving such stratigraphic trapping configurations are important for future exploration in Upper Austria, where most of the structural traps have been drilled. (orig.)

    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.

  20. Status of Baltic grey seals: Population assessment and extinction risk

    Directory of Open Access Journals (Sweden)

    Karin C Harding

    2007-01-01

    Full Text Available The grey seal (Halichoerus grypus population in the Baltic Sea is recovering after a century of bounty hunting and 3 decades of low fertility rates caused by environmental pollution. A conservative estimate of the population size in 2003 was 19,400 animals, and available data suggest an annual rate of increase of 7.5% since 1990. The growing population has led to increased interactions with the fishery, and demands are being raised for the re-introduction of the hunt. We provide a demographic analysis and a risk assessment of the population, and make recommendations on how to decrease the risk of over exploitation. Although hunting increases the risk of quasi-extinction, the risk can be significantly reduced by the choice of a cautious hunting regime. The least hazardous regimes allow no hunting below a ‘security level’ in population size. Obviously, to implement such a hunting regime detailed knowledge of the population size and growth rate is required. It is not possible to estimate “true” risks for quasi-extinction, but we used an approach where the relative difference for different scenarios can be compared. With a security level at 5,000 females, the population quasi-extinction risk increases 50 fold at an annual hunt of 500 females compared with a scenario with no hunting. The risk of quasi-extinction is very sensitive to declines in the mean growth rate and to increased variance in growth rate. The variance in the population estimates over the last 14 years imply that it would take 9 years to detect a declinefrom 1.075 to 1.027 in the rate of population increase. We also show how the age composition of killed animals influences the impact of the hunt. The overall recommendation is that hunting should be kept to a minimum, carefully documented and accompanied by close population monitoring.

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

    1994-06-01

    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

  2. Enrichment of omnivorous cercozoan nanoflagellates from coastal Baltic Sea waters.

    Kasia Piwosz

    Full Text Available Free-living nano-sized flagellates are important bacterivores in aquatic habitats. However, some slightly larger forms can also be omnivorous, i.e., forage upon both bacterial and eukaryotic resources. This hitherto largely ignored feeding mode may have pronounced implications for the interpretation of experiments about protistan bacterivory. We followed the response of an uncultured group of omnivorous cercozoan nanoflagellates from the Novel Clade 2 (Cerc_BAL02 to experimental food web manipulation in samples from the Gulf of Gdańsk (Southern Baltic Sea. Seawater was either prefiltered through 5 µm filters to exclude larger predators of nanoflagellates (F-treatment, or prefiltered and subsequently 1∶10 diluted with sterile seawater (F+D-treatment to stimulate the growth of both, flagellates and bacteria. Initially, Cerc_BAL02 were rapidly enriched under both conditions. They foraged on both, eukaryotic prey and bacteria, and were highly competitive at low concentrations of food. However, these omnivores were later only successful in the F+D treatment, where they eventually represented almost one fifth of all aplastidic nanoflagellates. By contrast, their numbers stagnated in the F-treatment, possibly due to top-down control by a concomitant bloom of other, unidentified flagellates. In analogy with observations about the enrichment of opportunistically growing bacteria in comparable experimental setups we suggest that the low numbers of omnivorous Cerc_Bal02 flagellates in waters of the Gulf of Gdańsk might also be related to their vulnerability to grazing pressure.

  3. SAR-Based Wind Resource Statistics in the Baltic Sea

    Full Text Available Ocean winds in the Baltic Sea are expected to power many wind farms in the coming years. This study examines satellite Synthetic Aperture Radar (SAR images from Envisat ASAR for mapping wind resources with high spatial resolution. Around 900 collocated pairs of wind speed from SAR wind maps and from 10 meteorological masts, established specifically for wind energy in the study area, are compared. The statistical results comparing in situ wind speed and SAR-based wind speed show a root mean square error of 1.17 m s−1, bias of −0.25 m s−1, standard deviation of 1.88 m s−1 and correlation coefficient of R2 0.783. Wind directions from a global atmospheric model, interpolated in time and space, are used as input to the geophysical model function CMOD-5 for SAR wind retrieval. Wind directions compared to mast observations show a root mean square error of 6.29° with a bias of 7.75°, standard deviation of 20.11° and R2 of 0.950. The scale and shape parameters, A and k, respectively, from the Weibull probability density function are compared at only one available mast and the results deviate ~2% for A but ~16% for k. Maps of A and k, and wind power density based on more than 1000 satellite images show wind power density values to range from 300 to 800 W m−2 for the 14 existing and 42 planned wind farms.

    The Second International Conference on Isotopes (2ICI) was hosted by the Australian Nuclear Association in Sydney, NSW, Australia. The Theme of the Second Conference: Isotopes for Industry, Health and a Better Environment recognizes that isotopes have been used in these fields successfully for many years and offer prospects for increasing use in the future. The worldwide interest in the use of research reactors and accelerators and in applications of stable and radioactive isotopes, isotopic techniques and radiation in industry, agriculture, medicine, environmental studies and research in general, was considered. Other radiation issues including radiation protection and safety were also addressed. International and national overviews and subject reviews invited from leading experts were included to introduce the program of technical sessions. The invited papers were supported by contributions accepted from participants for oral and poster presentation. A Technical Exhibition was held in association with the Conference. This volume contains the full text or extended abstracts of papers number 61- to number 114

    Directory of Open Access Journals (Sweden)

    Mezhevich N. M.

    2018-05-01

    Full Text Available This article considers military security in the Eastern Baltic. The research focuses on the economic sustainability of Estonia, Latvia, and Lithuania in the context of military spending. The authors maintain that an increase in military spending can either strengthen or weaken national economic and technological potential. In Germany or Sweden, military spending accounts for a smaller proportion of the GDP or budget revenues, but it is integrated into the general model of innovative and technological development. In the case of the Baltics, it is advisable to estimate military spending as a proportion of budget revenues rather than that of GDP — this recommendation applies to all smaller states. The authors stress that the central component of any national military and economic development is a focus on general national objectives rather than solely military ones. Economically advanced countries integrate defence spending into their investment and innovation strategies and industrial policies. Smaller countries — and the Baltics are no exception — do not apply this principle. Their military spending does not contribute to the technological and economic agenda. The article shows that the military spending of Lithuania, Latvia and Estonia undermines their investment potential and serves as a critical factor in their national and governmental development. The authors suggest estimating military spending as a proportion of budget revenues rather than that of GDP.

    In preparation for the 1994 International Conference on Population and Development, Egypt has deployed 14,000 police to protect participants from threatened violence. The Vatican has joined forces with Muslim fundamentalists to condemn the conference as a vehicle for imposing Western ideals, particularly abortion, on Third world countries. In addition, the opposition is raising the specter of a descent of homosexuals onto Cairo and Muslim fundamentalists have threatened to murder Western representatives. A suit filed by Islamic lawyers, aimed at stopping the conference, failed. Sudan and Saudi Arabia plan to boycott the conference, and it remains uncertain whether Libya will be represented. Conference organizers have not been deterred by the threats and note that the controversy has drawn public attention to the central issues under debate.

    Mussels within the Baltic Mytilus edulis × M. trossulus hybrid zone have adapted to the low salinities in the Baltic Sea which, however, results in slow-growing dwarfed mussels. To get a better understanding of the nature of dwarfism, we studied the ability of M. trossulus to feed and grow at low...... to become negative below 4.5 psu. We suggest that reduced ability to produce shell material at extremely low salinity may explain dwarfism of mussels in the Baltic Sea. Reduced bio-calcification at low salinity, however, may impede shell growth, but not somatic growth, and this may at first result...

    Within the framework of a research contract with the German Federal Environmental Agency the long range transport of trace metals over Europe and the deposition of trace metals into the North Sea and the Baltic Sea are estimated using the EMEP- (European Monitoring and Evaluation Programme) trajectory model. The methodology for the model calculations is explained. Preliminary results for the total deposition of lead into the North Sea and the Baltic Sea show, that the calculated values are lower than previous estimates based on extrapolations from measurements at coastal sites and ship measurements in the southern Baltic Sea, respectively.

    2014-03-01

    Full Text Available The aim of this paper is to analyze several aspects of digital publishing markets in Baltic countries. Estonia, Latvia and Lithuania have their own languages, so there are three different publishing markets. Results show that there are significant differences in the number of available titles, despite the fact that the Baltic e-book market is relatively new. The research on e-book sales identified the main e-book retailers and publishers in Baltic countries. E-books in Lithuanian, Latvian and Estonian available on sale were counted and the differences between e-book formats and the pricing in each country were established. The results showed that the smallest Baltic country, Estonia, has more e-books on sale than both Latvia and Lithuania. It is difficult to say if Latvia even has an e-book market at all. Lithuania is somewhere in the middle. Finally, an overview of the largest retailers and publishers is provided and overall publishing dynamics within the past 20 years is described.

    2015-09-01

    Full Text Available Recently developed system for assessment of radiation budget for the Baltic Sea has been presented and verified. The system utilizes data from various sources: satellite, model and in situ measurements. It has been developed within the SatBałtyk project (Satellite Monitoring of the Baltic Sea Environment - www.satbaltyk.eu where the energy radiation budget is one of the key element. The SatBałtyk system generates daily maps of the all components of radiation budget on every day basis. We show the scheme of making daily maps, applied algorithms and empirical data collection within the system. An empirical verification of the system has been carried out based on empirical data collected on the oil rig placed on the Baltic Sea. This verification concerned all the components of the surface radiation budget. The average daily NET products are estimated with statistical error ca. 13 Wm-2. The biggest absolute statistical error is for LWd component and equals 14 Wm-2. The relative error in relation to the average annual values for whole Baltic is the biggest for SWu and reaches 25%. All estimated components have correlation coefficient above 0.91.

    2017-12-01

    The marine acid-base system is relatively well understood for oceanic waters. Its structure and functioning is less obvious for the coastal and shelf seas due to a number of regionally specific anomalies. In this review article we collect and integrate existing knowledge of the acid-base system in the Baltic Sea. Hydrographical and biogeochemical characteristics of the Baltic Sea, as manifested in horizontal and vertical salinity gradients, permanent stratification of the water column, eutrophication, high organic-matter concentrations and high anthropogenic pressure, make the acid-base system complex. In this study, we summarize the general knowledge of the marine acid-base system as well as describe the peculiarities identified and reported for the Baltic Sea specifically. In this context we discuss issues such as dissociation constants in brackish water, different chemical alkalinity models including contributions by organic acid-base systems, long-term changes in total alkalinity, anomalies of borate alkalinity, and the acid-base effects of biomass production and mineralization. Finally, we identify research gaps and specify limitations concerning the Baltic Sea acid-base system.

  18. Tides in three enclosed basins: the Baltic, Black and Caspian seas

    Directory of Open Access Journals (Sweden)

    Igor P Medvedev

    2016-04-01

    Full Text Available Tides are the main type of sea level variability in the world ocean. However, oceanic tides penetrate weakly, or do not penetrate at all, into enclosed basins such as the Baltic, Black and Caspian seas. Consequently, only directly forced tides are formed in these basins. Long observation time series (up to 123 years in the Baltic Sea and 38 years in the Black and Caspian seas at numerous stations were used to precisely estimate tidal constituents. High-resolution spectra revealed fine structure of discrete peaks at tidal frequencies. The diurnal radiational constituent S1 (1 cpd, apparently associated with breeze winds, was found to play an important role in general tidal dynamics in these seas. Harmonic analysis of tides for individual yearly series with consecutive vector averaging over the entire observational period was applied to estimate mean amplitudes and phases of tidal constituents. Our findings indicate that the formation and predominance of diurnal or semidiurnal tides in these seas appears to depend on the frequency-selective properties of the basins. Thus, in the Baltic Sea with fundamental modal period of about 27 h, diurnal tides dominate in the major eastern gulfs. In the Black Sea resonant amplification of semidiurnal tides is observed in the northwestern part. The predominance of semidiurnal tides in the Caspian Sea has also probably a resonant nature. Maximum tidal heights estimated for a 100-year period are 23 cm in the Baltic Sea, 18 cm in the Black Sea and 21 cm in the southern Caspian Sea.

    In September/October 1980 complex field studies on the distribution of heavy metals, petroleum hydrocarbons, chlorinated hydrocarbon and radionuclides were carried out on 24 stations in the Baltic Sea. Samples of different compartments of the marine environment were taken. The analyses for some heavy metals in water were performed directly on board. First results including mean values and concentration ranges for Hg, Cd, Pb, Cu, Zn, Sr-90 and Cs-137 in Baltic waters and for petroleum hydrocarbons, PCBs, DDT metabolites, HCB, α-HCH and γ-HCH in water and surface film samples are given. In most cases the data confirm recently published results. Relatively low concentrations were found for mercury. The investigations were repeated in May/June 1981 covering the Baltic Sea and parts of the North Atlantic. The resultant data for heavy metals and petroleum hydrocarbons agree widely with the results from 1980. An estimation of the relative pollutant burden of the Baltic Sea related to the investigated parts of the North Atlantic is given. (author)

  4. 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.

    The paper presents a new marine ecosystem model 3D CEMBS designed for the Baltic Sea. The ecosystem model is incorporated into the 3D POPCICE ocean-ice model. The Current Baltic Sea model is based on the Community Earth System Model (CESM from the National Center for Atmospheric Research) which was adapted for the Baltic Sea as a coupled sea-ice model. It consists of the Community Ice Code (CICE model, version 4.0) and the Parallel Ocean Program (version 2.1). The ecosystem model is a biological submodel of the 3D CEMBS. It consists of eleven mass conservation equations. There are eleven partial second-order differential equations of the diffusion type with the advective term for phytoplankton, zooplankton, nutrients, dissolved oxygen, and dissolved and particulate organic matter. This model is an effective tool for solving the problem of ecosystem bioproductivity. The model is forced by 48-hour atmospheric forecasts provided by the UM model from the Interdisciplinary Centre for Mathematical and Computational Modelling of Warsaw University (ICM). The study was financially supported by the Polish State Committee of Scientific Research (grants: No N N305 111636, N N306 353239). The partial support for this study was also provided by the project Satellite Monitoring of the Baltic Sea Environment - SatBaltyk founded by European Union through European Regional Development Fund contract no. POIG 01.01.02-22-011/09. Calculations were carried out at the Academy Computer Centre in Gdańsk.

    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.

    The eastern Baltic (EB) cod (Gadus morhua) stock was depleted and overexploited for decades until the mid-2000s, when fishing mortality rapidly declined and biomass started to increase, as shown by stock assessments. These positive developments were partly assigned to effective management measure...

  9. Future changes in the Baltic Sea acid–base (pH and oxygen balances

    Full Text Available Possible future changes in Baltic Sea acid–base (pH and oxygen balances were studied using a catchment–sea coupled model system and numerical experiments based on meteorological and hydrological forcing datasets and scenarios. By using objective statistical methods, climate runs for present climate conditions were examined and evaluated using Baltic Sea modelling. The results indicate that increased nutrient loads will not inhibit future Baltic Sea acidification; instead, the seasonal pH cycle will be amplified by increased biological production and mineralization. All examined scenarios indicate future acidification of the whole Baltic Sea that is insensitive to the chosen global climate model. The main factor controlling the direction and magnitude of future pH changes is atmospheric CO2 concentration (i.e. emissions. Climate change and land-derived changes (e.g. nutrient loads affect acidification mainly by altering the seasonal cycle and deep-water conditions. Apart from decreasing pH, we also project a decreased saturation state of calcium carbonate, decreased respiration index and increasing hypoxic area – all factors that will threaten the marine ecosystem. We demonstrate that substantial reductions in fossil-fuel burning are needed to minimise the coming pH decrease and that substantial reductions in nutrient loads are needed to reduce the coming increase in hypoxic and anoxic waters.

  11. Ecohydrodynamic model of the Baltic Sea. Part 1. Description of the ProDeMo model

    Bogdan Ołdakowski

    2005-12-01

    Full Text Available The ProDeMo (Production and Destruction of Organic Matter Model, a 3D coupled hydrodynamic-ecological model, was formulated and applied to the whole Baltic Sea and the subregion of the Gulf of Gdansk. It describes nutrient cycles (phosphorus, nitrogen, silicon through the food web with 15 state variables, oxygen conditions and the parameterisation of water-sediment interactions. The present version of the model takes two groups of phytoplankton - diatoms and non-diatoms - as well as zooplankton into consideration. It covers the flow of matter and energy in the sea, including river discharges and atmospheric deposition. Numerical applications are embedded on a 1 NM grid for the Gulf of Gdansk and a 5 NM grid for the Baltic Sea.     Since the model results largely concur with observations, the model can be regarded as a reliable tool for analysing the behaviour of the Baltic ecosystem. Some examples of the spatial-temporal variability of the most important biological and chemical parameters are presented. The model results are compared with those of other modelling research in the Baltic Sea.     Both the ProDeMo model algorithm and its computing procedures need to be further developed. The next version should therefore enable more phytoplankton groups to be defined, for example cyanobacteria, which are able to take up molecular nitrogen from the atmosphere (nitrogen fixation. Additionally, the sediment phase should be divided into active and non-active layers.

This paper identifies management issues and suggests actions...... to be considered for post-invasion management. Priority should be given to the establishment of a coordinated pan-Baltic monitoring programme and associated data storage and exchange, as well as the compilation of landing statistics of the round goby in commercial and recreational fisheries. While eradication...... is unrealistic, population control that leads to minimising the risk of transfer to yet uncolonised areas in the Baltic Sea and adjacent waterbodies is feasible. This should comprise the requirement that the species be landed in commercial fishery bycatch, the management of ships’ ballast water and sediments...

  17. Major infrastructure projects and the foreign policy of the Baltic states in 2010—2014

    Mezhevich N. M.

    2014-02-01

    Full Text Available At the current stage of social development, particular attention is drawn to studies that assess major infrastructure — and thus political — projects aimed at a qualitative breakthrough in the socio-economic development of the countries under investigation. The scheduled multi-billion investments into energy sector are of political rather than economic nature. The projects to develop alternative power grids and high-speed railways can result in large-scale economic downturns diminishing the prospects of balanced social development. The author addresses the classical concepts of the theory of regional economy and new economic geography and their interpretation of the interconnection between political and economic factors. The article aims to demonstrate the inconsistency between political and economic objectives of the development of the Baltics. The study contributes to a broader set of research into the issues of post-Soviet economic and political development. The Baltic States follow their own political and economic ways. The study proves the hypothesis of low efficiency of large infrastructure project and their political motivation. It is concluded that the disregard of the factor of mutually beneficial economic cooperation with Russia destabilizes the development of national economic of the Baltic States. The author believes that modern infrastructure projects in the Baltic Sea region should be integrated into both western and eastern dimensions.

  20. Diversity of pico- to mesoplankton along the 2000 km salinity gradient of the Baltic Sea

    Full Text Available Microbial plankton form the productive base of both marine and freshwater ecosystems and are key drivers of global biogeochemical cycles of carbon and nutrients. Plankton diversity is immense with representations from all major phyla within the three domains of life. So far, plankton monitoring has mainly been based on microscopic identification, which has limited sensitivity and reproducibility, not least because of the numerical majority of plankton being unidentifiable under the light microscope. High-throughput sequencing of taxonomic marker genes offers a means to identify taxa inaccessible by traditional methods; thus, recent studies have unveiled an extensive previously unknown diversity of plankton. Here, we conducted ultra-deep Illumina sequencing (average 105 sequences/sample of rRNA gene amplicons of surface water eukaryotic and bacterial plankton communities sampled in summer along a 2000 km transect following the salinity gradient of the Baltic Sea. Community composition was strongly correlated with salinity for both bacterial and eukaryotic plankton assemblages, highlighting the importance of salinity for structuring the biodiversity within this ecosystem. In contrast, no clear trends in alpha-diversity for bacterial or eukaryotic communities could be detected along the transect. The distribution of major planktonic taxa followed expected patterns as observed in monitoring programs, but groups novel to the Baltic Sea were also identified, such as relatives to the coccolithophore Emiliana huxleyi detected in the northern Baltic Sea. This study provides the first ultra-deep sequencing-based survey on eukaryotic and bacterial plankton biogeography in the Baltic Sea.
