    industrial customers to participate in the Joint Baltic electricity Market but the aim is a step-by-step opening of the market to comprise a larger number of customer groups. This will in its turn pave the way for a rapid EU adjustment of the Baltic electricity market and a more practical connection to the neighbouring markets, for example the Nordic Electricity Market. The Nordic Electricity Market is one good example of a successful way for regional market integration, which is used as a model and source of positive experiences in other regions, both within the EU and in the candidate countries. The Baltic authorities are interested to make further use of the Nordic experiences and to introduce an electricity market, which in its construction is very similar to the Nordic model. This will make it even more interesting for the Nordic authorities and actors to follow the development in the Baltic States and to finds ways and means for more practical co-operation and partnership. It shall also be noted that the support from the Nordic Countries, including through the Nordic Council of Ministers for Energy, to the reform and adjustment to the EU policies and requirement of the energy sector in the Baltic States has increased in recent years. In this context the co-operation established within BASREC - the Baltic Sea Region Energy Co-operation - where electricity market issues constitutes one of four main areas shall be observed

    2013-07-01

    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)

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

    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.

  7. BALTIC STATES IN THE EUROZONE: THE ACCESSION PROCESS AND RESULTS

    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.

  9. 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.

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

    Canfield, J.L.

    1993-01-01

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

  11. Foreign Direct Investment Attraction in the Baltic States

    2014-06-01

    Full Text Available This paper considers the importance of macroeconomic factors as well as investment climate for foreign direct invest­ ment attraction in the Baltic states. It reviews some of the indicators for measuring the investment climate and their usefulness as indicators of strength of FDI attraction and uses the results of econometric analysis to consider relative importance of various macroeconomic factors. The results suggest that perceptions of corruption and fiscal policy are some of the more important drivers of FDI attraction. The paper also considers several measures that could improve foreign direct investment attraction in the Baltic States such as expanding the protection of property rights and improving the quality of infrastructure.

    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.

    Full Text Available The article analyses models of administrative supervision of local self-government in the Baltic States (Latvia, Lithuania, Estonia highlighting the advantages and disadvantages of these models. The research done in this article defines the theoretical concept of administrative supervision of local self-government; gives an overview of the legislative framework underpining the key administrative supervision bodies of local self-government in the Baltic States; discusses the issue of legal regulation and the present state of administrative supervision over local self-government units in the Baltic States; gives some theoretical and practical suggestions to develop this field in the Baltic States.The research methods employed in preparation of this article are theoretical methods of analysis of scientific literature and sources, legal acts and documents as well as comparative and logical analysis, induction and generalisation. Three Baltic States similar in their area, number of inhabitants, and governmental peculiarities have been chosen for the analysis.

  16. Responsible Lending in Banks of the Baltic States

    2013-12-01

    Full Text Available The aim of this article is to clarify basic principles of responsible lending in lending agreements between banks and individuals in Latvia, as well as in the existing legislation in the Baltic States that regulates this process. In order to obtain research results, the authors performed qualitative analysis of scientific literature on the issues of responsible lending; legislation that regulates mortgage lending in the Baltic States; successful experience of banks in other countries; information available on home pages of banks about commercial bank loan volumes for mortgage loans with different types of real estate asset backing; information included in loan agreements of four commercial banks in Latvia and its compliance with the laws and regulations. Loan borrower evaluation stages for review of a new loan application were developed. On the basis of loan agreement analysis, the authors elaborated a formula of monthly loan payments for bank customers who experience unfavourable financial conditions. As a result of the research, the authors came to a conclusion that in Latvia and Estonia there is no legislation that directly regulates mortgage loans. During the research the authors also faced some restrictions, as not all banks in Latvia, which continue lending activities, are willing to give information included in loan agreements.

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

    Directory of Open Access Journals (Sweden)

    Smirnov Vadim

    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.

    Analysing the evolution and determinants of foreign direct investment (FDI) in Estonia, Latvia and Lithuania, this paper argues that sound economic policies have created an environment conducive for FDI. 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 ...

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

    Directory of Open Access Journals (Sweden)

    Koyama Yoji

    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.

  1. Energy dependency and sustainable regional development in the Baltic states: A review

    Directory of Open Access Journals (Sweden)

    Štreimikienė Dalia

    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.

  2. 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.

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

    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.

  6. Renewable Energy in the Baltic States. Different Situations

    International Nuclear Information System (INIS)

    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

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

    Directory of Open Access Journals (Sweden)

    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.

  8. On crisis trends in the legitimacy of the political regimes of the Baltic States

    Directory of Open Access Journals (Sweden)

    Smirnov Vadim

    2015-11-01

    Full Text Available This article considers the legitimacy of political regimes in the Baltic States by analysing three major parameters: confidence in political institutions, level of corruption, and the development of their party systems. The author identifies the major crisis trends in the legitimacy of the political regimes of Lithuania, Latvia, and Estonia. The article stresses the problem of legitimacy reproduction resulting from the limited representation of the national party systems. Special attention is paid to compensatory mechanisms used by political elites to ‘artificially’ reproduce legitimacy. It makes sense to analyse the deficit of legitimacy in the Baltic States not only in the context of threats to democratic institutions but also considering weaknesses of public institutions and insufficient resources to ensure stateness. This requires developing a hypothesis about smaller states ‘importing’ legitimacy from larger states and intergovernmental organisations, in whose zone of influence they are included. In other words, the EU and NATO can provide smaller states not only with economic and military resources but also legitimation ‘resources’ using their prestige to support the belief of local residents that there is no alternative to the current political system of social organisation. Legitimacy deficit increases the risks of a rift between political elites in the Baltic States, which can become a prologue to a deep political crisis. In these conditions, compensatory mechanisms cannot be considered as targeted exclusively at broad social strata. They are also aimed at political elites, whose consolidation or ‘encapsulation’ is achieved by exaggerating external threats and resorting to repressive measures in an attempt to develop an ethnonational consensus. These methods are used to ensure self-preservation of the Baltic States political regimes within the current ideological and institutional configuration.

    Full Text Available Despite quite similar conditions (natural resources for electricity production from renewable energy sources (RES-E in three Baltic States (Estonia, Latvia and Lithuania, significant differences exist in these countries as to the RES-E production volume. In Latvia this volume is the highest, while in Estonia and Lithuania it is half as high. One of the factors that determine the RES-E production volumes is support policies, which in the Baltic States are different. The main objective of this work was to analyze and compare these support policies. The results have shown that for rapid RES-E development the most effective policy is to be market-oriented (as in Estonia, whereas for more stable development such policy should be producer-oriented (as in Lithuania.

    Hitherto, the Stone age of the East Baltic was known for its series of Late Mesolithic - Early Neolithic dates, but over the past decade the number of the dates for the Middle Stone Age and the Final Palaeolithic has also increased. The article brings together the published Palaeolithic and Mesolithic dates from the East Baltic, based on radiocarbon age. This is because a proportion of the dates has never been calibrated, while a proportion of the new dates have been calibrated using various software programmes, often without stating the programme used. For the first time, radiocarbon dates have been obtained for the Late Palaeolithic in Lithuania: 10 550-9820 BP (cal. 10 600-9000 BC). This period is connected with the Swidry Culture in the central and southern part of the East Baltic. At the present best-dated stage of the Mesolithic is the Early Mesolithic, with several dates from Estonia (Pulli, Kunda-Lammasmagi) and Latvia, covering the period 9600 to around 9000 BP (cal. 8900-8300 BC). These dates are also supported by dates obtained from Mesolithic sites in neighbouring areas: northern Poland, southern Finland and north-east Russia. Much has been gained from the dating in recent years of burials in Lithuania and Latvia. Currently the oldest known burial is male buried in the cultural layer of Zvejnieki II settlement site, dated to 8240 BP. Another three burials in Lithuania,in the Spiginas and Duonkalnis cemeteries, as well as eight burials at Zvejnieki cemetery, date from the late Mesolithic, confirming the idea that it was in the Late Mesolithic that large special burial sites developed adjacent to settlements in the Baltic basin, both in the east and west. The development of cemeteries in Lithuania began in the period 7780-7470 BP, while the Late Mesolithic graves at Zvejnieki date from 6900-6400 BP. The dates show that a special feature of the cemeteries in the Baltic is their long duration of use, starting from the Middle Mesolithic up to the end of the

    Full Text Available The Baltic countries - the next neighbors of Russia, whose history is closely linked with our country in the period of Kievan Rus, the Grand Duchy of Moscow, the Russian Empire, the Soviet Union, and today in a broad European context. Both Russia and the Baltic states are the states that make up the Baltic region. The role of this region in the European integration is the key. The border between Russia and the European Union, Russia and the EU are in direct contact, there is a direct interaction between the peoples of Europe, divided by confrontations of the twentieth century. In this border area sociocultural diffusion occurs between the two parts of the European continent. Factor of cooperation of neighbors is an essential guarantee of stability of the world system. For this cooperation to be productive, you must have an adequate view of the neighbors, about the processes that take place there. Knowing immediate environment in a globalized world is a prerequisite for good neighborly relations. The condition of willingness to help, if needed. In the current civilization elevated risk mutual definitely be in demand. Historical experience shows that the lack of objective knowledge is the cause of misunderstanding, and often the source of origin of enmity. This is not only of interest to neighboring nations, but the need to have certain knowledge about them, are closely linked to historical responsibility. Feature stories is that it is inextricably linked with modernity. For public decision-making needs of reliable knowledge about the processes that led to the present, the historical conditions of social psychology folding neighboring nations, forms of expression of their national characteristics. On the basis of sociological methods - from the study of documentary and literary sources, analysis of the results of mass surveys to group discussions and participant observation - analyzes the problems of mutual Russian and Baltic peoples.

    In this contribution the gender equality problem in physics will be discussed on the basis of the results obtained implementing the project ``Baltic States Network: Women in Sciences and High Technology'' (BASNET) initiated by Lithuanian women physicists and financed by European Commission. The main goal of BASNET project was creation of the regional Strategy how to deal with women in sciences problem in the Baltic States. It has some stages and the contribution follows them. The first one was in depth sociological study aiming to find out disincentives and barriers women scientists face in their career and work at science and higher education institutions. Analysis of results revealed wide range of problems concerned with science organization, management and financing common for both counterparts. However it also proved the existence of women discrimination in sciences. As main factors influencing women under-representation in Physics was found: the stereotypes existing in the society where physics is assigned to the masculine area of activity; failings of the science management system, where highest positions are distributed not using the institutionalized objective criteria but by voting, where the correctness of majority solutions is anticipated implicitly. In physics where male scientists are the majority (they also usually compose executive boards, committees etc.) results of such a procedures often are unfavorable for women. The same reasons also influence women ``visibility'' in physicist's community and as the consequence possibility to receive needed recourses for their research as well as appropriate presentation of results obtained. The study revealed also the conservatism of scientific community- reluctance to face existing in the scientific society problems and to start solving them. On the basis of the results obtained as well practice of other countries the common strategy of solving women in physics (sciences) in the Baltic States region was

  17. The influence of major rivers discharges on physical and biological state of the Baltic Sea

    Science.gov (United States)

    Dudkowska, Aleksandra; Cieszyńska, Agata

    2017-04-01

    River discharges are one of very important factors affecting the marine ecosystem functioning. Land-originated inflows, carrying fresh, nutrient-rich water can be often defined as the factor responsible for creating new physical and biochemical conditions, which in turn can create more or less favorable medium for many marine organisms to run their biological cycles within. In some basins, the Baltic Sea including, land-originated water inflows are usually associated with the eutrophication and are the factors, which trigger this process. It is clear that not only because of the riverine discharges, the nutrients levels in the sea increase. To exemplify in the case of phosphorus, the nutrient concentration can be raised by 'internal re-loading', which is caused by phosphorus pools accumulated in the sediments of the sea bed being released back to the water under anoxic conditions. In the present study, we focused on the major Baltic rivers inflows and their impact on the environmental state of the basin. We have examined river discharges (expressed as volumetric inflow in m3 s-1) and the nutrient load (phosphorus, nitrogen) accompanied by these inflows. Data for our investigation were derived from EHype model (Swedish Meteorological Institute Server, http://hypeweb.smhi.se/europehype/time-series/). From the river discharge model data set spanned over 1981 - 2010, we have calculated long-term trends and the basic statistics: annual and monthly means, percentiles (10th, 50th, 90th). The trends were defined to be statistically significant at the confidence level of 95% (p contract number: 2012/07/N/ST10/03485) entitled: "Improved understanding of phytoplankton blooms in the Baltic Sea based on numerical models and existing data sets".

    2017-01-01

    This paper presents a multi-criteria selection approach for offshore wind sites assessment. The proposed site selection framework takes into consideration the electricity network’s operating security aspects, economic investment, operation costs and capacity performances relative to each potential site. The selection decision is made through Analytic Hierarchy Process (AHP), with an inherited flexibility that aims to allow end users to adjust the expected benefits accordingly to their respective and global priorities. The proposed site selection framework is implemented as an interactive case study for three Baltic States in the 2020 time horizon, based on real data and exhaustive power network models, taking into consideration the foreseen upgrades and network reinforcements. For each country the optimal offshore wind sites are assessed under multiple weight contribution scenarios, reflecting the characteristics of market design, regulatory aspects or renewable integration targets. - Highlights: • We use a multi-criteria selection approach for offshore wind sites assessment. • Security aspects, economic investment, operation costs and capacity performances are included. • The selection decision is made through an Analytic Hierarchy Process (AHP). • We implement the methodology as a case study for three Baltic States in the 2020 time horizon.

The objective is to provide information on the context, in which regional energy policy instruments have to operate, and which has to be taken into consideration when compiling energy development measures for regional development and structural funds. The major issue of the publication is to discuss perspective of the formation methodology for energy management integration into development of regional planning documents. The main objective of this publication is to make a brief overview of what are the prospects of regional energy development. The place of municipal and regional energy development programs in general energy investment strategy is defined. The guidelines for regional energy programs are presented

  1. Analyses of energy supply options and security of energy supply in the Baltic States

    International Nuclear Information System (INIS)

    2007-02-01

    In its broadest meaning 'energy security' is the ability of a nation to muster the energy resources needed to ensure its welfare. In a narrower meaning it refers to territorial energy autonomy. Consequently, energy supply security is a matter of both domestic policy and international relations. Perceived and real threats may be economic or logistic, politically motivated or the result of war or natural causes. They may be source, technology or transport related, specific to a facility or a function of system structure, due to sabotage or to inadequate investment or maintenance, or result from pricing or regulatory policies. Energy security has become a growing concern in the Baltic States of Estonia, Latvia and Lithuania since regaining independence in 1991. As their national energy systems depend on essentially one single foreign supplier for most of their oil and all of their natural gas supplies, a comprehensive analysis of potential measures to improve security including alternative supply options becomes vital. Such an analysis needs to consider, for example, the availability of domestic energy reserves and resources, the vintage of existing energy infrastructures (including regional and interregional interconnections), storage facilities, as well as future technology and energy trade options. However, the Baltic States' accession to the European Union in 2004 has added further responsibilities with regard to energy security. Robust future energy development strategies, for each individual country and the region as a whole, will also require compliance with EU regulations, as well as with special stipulations formulated in the accession agreements. Robust energy strategies need to strike a balance between the potentially conflicting dimensions of energy security, economic efficiency and environmental protection. For example, supply security is likely to incur an 'insurance premium', while environmental protection may well raise the cost of providing energy

  2. Institutional frameworks for sustainability? A comparative analysis of the forest sectors of Russia and the Baltic States.

    2004-08-01

    After the break-up of the Soviet system, the divergence in forest management among Soviet republics became obvious. While the forest sectors of the Baltic States have been fundamentally changed, Russia has not been able to develop an institutional framework that would fit the prerequisites for social-ecological resilience. It is argued that sustainable development requires institutional frameworks that have the capacity to adapt and learn, and thus to treat policies as experiments that are constantly assessed and readjusted. This, however, requires a participatory approach and in this respect the Baltic States are believed to be on a more promising track. Finally, it is concluded that only to the extent that suitable institutional frameworks will be developed will social-ecological resilience be a significant feature of the natural resources management in the former communist countries.

    Full Text Available The paper describes the evaluation of the construction market performance in three Baltic States, including Estonia, Latvia, Lithuania and Poland, based on using structural statistical criteria. The evaluation covers various periods of time, embracing the time before the economic crisis, in 2007, during the economic crisis, in 2009, and after the economic crisis, in 2013. For assessing the efficiency of their construction sectors’ performance, the investigated countries are arranged in the order of preference according to this indicator by using three multiple-criteria decision making methods (MCDM, such as SAW, TOPSIS and COPRAS. These evaluation methods are based on determining the weights of the structural criteria used. For this purpose, three various methods, including the entropy, the method of the criteria impact loss (CILOS and a new method of determining the objective criteria weights (IDOCRIW suggested by the authors. The results obtained allowed the researchers to assess the construction market performance in the considered states in various periods of time, to compare them with other countries and to rank them based on this parameter. Therefore, the suggested method of market performance evaluation may be used as an effective supplementary aid for determining the priorities in the future business development, as well as for studying the competitive markets or directing the cash flows of an enterprise to the appropriate areas.

  7. Non-equivalent stringency of ethical review in the Baltic States: a sign of a systematic problem in Europe?

    2011-01-01

    We analyse the system of ethical review of human research in the Baltic States by introducing the principle of equivalent stringency of ethical review, that is, research projects imposing equal risks and inconveniences on research participants should be subjected to equally stringent review procedures. We examine several examples of non-equivalence or asymmetry in the system of ethical review of human research: (1) the asymmetry between rather strict regulations of clinical drug trials and relatively weaker regulations of other types of clinical biomedical research and (2) gaps in ethical review in the area of non-biomedical human research where some sensitive research projects are not reviewed by research ethics committees at all. We conclude that non-equivalent stringency of ethical review is at least partly linked to the differences in scope and binding character of various international legal instruments that have been shaping the system of ethical review in the Baltic States. Therefore, the Baltic example could also serve as an object lesson to other European countries which might be experiencing similar problems. PMID:20606000

    Full Text Available Climate change has been shown to impact aspects of agriculture and phenology. This study aims to quantify changes in the timing of garden strawberry blooms and harvests in the Baltic States using Regional Climate Models (RCMs. First, parameters for a strawberry phenology model based on the growing degree day (GDD methodology were determined. Growing degree days were calculated using a modified sine wave method that estimates the diurnal temperature cycle from the daily maximum and minimum temperature. Model parameters include the base temperature and the required cumulative GDD sum, estimated from phenological and meteorological observations in Latvia for the years 2010–2013 via iterative calibration. Then an ensemble of bias-corrected RCM results (ENSEMBLES project was used as input to the phenological model to estimate the timing of strawberry phenological processes for the years 1951–2099. The results clearly show that strawberry phenological processes can be expected to occur earlier in the future, with a significant change in regional patterns. Differences between coastal and inland regions are expected to decrease over time. The uncertainty of the results was estimated using the RCM ensemble spread, with northern coastal locations showing the largest spread.

    2014-05-01

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

    Full Text Available Daugavpils (Latvia and Narva (Estonia are cities in the Baltic States and significant cultural and economic centres of their respective countries. These cities are characterized by a minority of nationals (19.8% of residents of Daugavpils are Latvian, 4% of residents of Narva are Estonian and a similar linguistic situation: there is a dominance of Russian in the press, television and radio, but the state language prevails in the urban language signs. The aim of the study is to analyse the linguistic and extralinguistic means used for the creation of ergonyms of educational and cultural spheres. The main criteria for the analysis are: language choice, grammatical structures, sources of precedent and semantic groups. The data for this study were collected in city websites. Some conclusions: 1 Mixed proper names (the direct name and symbolical name prevail: in Daugavpils there are more mixed names in the field of education, while in Narva there are more mixed names in the culture sphere. Onymization of nomenclature names can be observed. 2 Ergonyms are mostly created in the official language. In Narva, there is explicit use of Russian (directly as the first/second or third language and indirectly – in transliteration. 3 In symbolical names, there are more lexemes representing or characterizing wildlife, while in Narva also the potential of mythology, literature and cinema is used. Denotative precedent is more often found in the names of informal educational institutions and the cultural sphere, connotative precedent – in the names of kindergartens. 4 In general, it must be concluded that the specific things characteristic to the local environment are used more often in Narva, while respecting the unique experience of minorities.

    Full Text Available The transformation of urban policy, resulting from ‘creative industries’ policy developments, is explored in this article, with respect to the Baltic capitals. Policy initiatives in the creative industries in Central and Eastern European cities have predominantly developed through policy transfers from Western Europe, with its long-term market economy experience. How adaptable are such policies for post-socialist cities? Using the concept of social innovation, this article describes mechanisms that facilitate policy acceptance and examines whether and how the development of creative industries has resulted in urban policy renewal in the Baltic capitals.

    2016-04-01

    In 2009, brief but deep economic crisis profoundly affected the three Baltic States: Estonia, Latvia and Lithuania. In response, all three countries adopted severe austerity measures with the shared goal of containing rising deficits, but employing different methods. In this article, we analyze the impact of the economic crisis and post-crisis austerity measures on health systems and access to medical services in the three countries. We use the EU-SILC data to analyze trends in unmet medical need in 2005-2012, and apply log-binomial regression to calculate the risk of unmet medical need in the pre- and post- crisis period. Between 2009 and 2012 unmet need has increased significantly in Latvia (OR: 1.24, 95% confidence interval (CI): 1.15-1.34) and Estonia (OR: 1.98, 95% CI: 1.72-2.27), but not Lithuania (OR: 0.84. 95% CI: 0.69-1.04). The main drivers of increased unmet need were inability to afford care in Latvia and long waiting lists in Estonia. The impact of the crisis on access to care in the three countries varied, as did the austerity measures affecting their health systems. Estonia and Latvia experienced worsening access to care, largely exacerbating already existing barriers. The example of Lithuania suggests that deterioration in access is not inevitable, once health policies prioritise maintenance and availability of existing services, or if there is room for reducing existing inefficiencies. Moreover, better financial preparedness of health systems in Estonia and Lithuania achieved some protection of the population from increasing unmet need due to the rising cost of medical care. © The Author 2015.

    Cross-country comparisons of unofficial payments in the health sector are sparse. In 2002 we conducted a social audit of the health sector of the three Baltic States. Some 10,320 household interviews from a stratified, last-stage-random, sample of 30 clusters per country, together with institutional reviews, produced preliminary results. Separate focus groups of service users, nurses and doctors interpreted these findings. Stakeholder workshops in each country discussed the survey and focus group results. Nearly one half of the respondents did not consider unofficial payments to health workers to be corruption, yet one half (Estonia 43%, Latvia 45%, Lithuania 64%) thought the level of corruption in government health services was high. Very few (Estonia 1%, Latvia 3%, Lithuania 8%) admitted to making unofficial payments in their last contact with the services. Around 14% of household members across the three countries gave gifts in their last contact with government services. This social audit allowed comparison of perceptions, attitudes and experience regarding unofficial payments in the health services of the three Baltic States. Estonia showed least corruption. Latvia was in the middle. Lithuania evidenced the most unofficial payments, the greatest mistrust towards the system. These findings can serve as a baseline for interventions, and to compare each country's approach to health service reform in relation to unofficial payments.

    2017-10-01

    Full Text Available Sustainable development is inconceivable without healthy real estate market. A housing project can be regarded as sustainable only when all the dimensions of sustainability (environmental, economic, and social are dealt with. There has been an increased interest in using sustainability indicators for evaluating the impacts of the new development projects. Although international literature is rich in sustainability assessments, there are no tools developed for assessment of new residential projects in the specific context of the Baltic States. Therefore, the aim of this article is to fill this gap and to propose an integrated, hierarchically structured system of sustainability indicators to be used for assessment of the new housing development projects. This aim is achieved through accomplishing three objectives. First, based on a review of literature related to assessing building project performance and sustainable development in construction, the paper proposes an original hierarchically structured system of sustainability indicators suitable for the Baltic context. Second, based on a survey of experts, significances of criteria are estimated by the Analytic Hierarchy Process (AHP method. Finally, paper proposes recommendations to government authorities and real estate developers as to how to enhance the performance of new residential projects according to the principles of sustainability.

    The Ohio River Valley Water Sanitation Commission (ORSANCO), in cooperation with the United States EPA, is completing it role in assisting the Baltic Countries of Estonia, Latvia, Lithuania and Kaliningrad Oblast, Russia with watershed management capacity building demonstration projects under the Great Lakes/Baltic Sea Partnership Program. The Countries of Estonia, Latvia and Lithuania view the skills gained through this program as important to their objective of complying with the European Union's Water Framework Directive and thus facilitating accession into the European Union. The program also addressed Kaliningrad's desire to work cooperatively with their neighboring countries concerning shared waters. Three watershed demonstration projects were designed and implemented, two of which involved joint country efforts: Parnu River (Estonia) modeling for nutrients and bacteria survey; river basin assessment and management planning for the Lielupe Basin (Latvia and Lithuania); and data base development and cooperative water quality survey and analysis for the Sesupe River (Lithuania and Kaliningrad). The benefits of the projects include enhancing the country's technical skills and the forging of relationships, without which achieving effective watershed management will be difficult to achieve.

    Quite a few hold the view that nuclear energy will have its renaissance in the not too distant future. Technology is, however, a necessary, but not sufficient condition. The needed prerequisites represent a complex issue. With increasing energy demand and depletion of non-renewable energy resources, nuclear will have to prove its role in an increasing energy mix, globally, regionally and often also nationally. Based on its history, experience with coordinated interplay in electricity production from a variety of energy sources, and science engagements, we argue for a future Nordic/Baltic SHOWCASE: A nuclear weapons free and proliferation safe nuclear energy supplier in the region, with a concerted role in competence building and in international ventures, and with focus on operation, safety, economy and societal aspects.

    Full Text Available Rabies is a fatal zoonosis that still causes nearly 70, 000 human deaths every year. In Europe, the oral rabies vaccination (ORV of red foxes (Vulpes vulpes was developed in the late 1970s and has demonstrated its effectiveness in the eradication of the disease in Western and some Central European countries. Following the accession of the three Baltic countries--Estonia, Latvia and Lithuania--to the European Union in 2004, subsequent financial support has allowed the implementation of regular ORV campaigns since 2005-2006. This paper reviews ten years of surveillance efforts and ORV campaigns in these countries resulting in the near eradication of the disease. The various factors that may have influenced the results of vaccination monitoring were assessed using generalized linear models (GLMs on bait uptake and on herd immunity. As shown in previous studies, juveniles had lower bait uptake level than adults. For the first time, raccoon dogs (Nyctereutes procyonoides were shown to have significantly lower bait uptake proportion compared with red foxes. This result suggests potentially altered ORV effectiveness in this invasive species compared to the red foxes. An extensive phylogenetic analysis demonstrated that the North-East European (NEE rabies phylogroup is endemic in all three Baltic countries. Although successive oral vaccination campaigns have substantially reduced the number of detected rabies cases, sporadic detection of the C lineage (European part of Russian phylogroup underlines the risk of reintroduction via westward spread from bordering countries. Vaccine induced cases were also reported for the first time in non-target species (Martes martes and Meles meles.

    The accession of Estonia, Latvia and Lithuania to the EU sets the target to integrate electricity sectors of these Baltic States into a common electricity sector of the EU. The integration of the electricity sectors is one of the most important economic and technical problems. For solving these problems, large-scale financing investments are needed, as well as technical and organisational efforts from the three Baltic States and from the EU. (orig.)

  5. Analysis of the Validity of Environmental Kuznets Curve for the Baltic States

    Lapinskienė, Giedrė; Tvaronavičienė, Manuela; Vaitkus, Pranas

    2013-12-01

    The paper analyses a traditional Environmental Kuznets Curve (EKC) relationship between greenhouse gases (GHG) and gross domestic product (GDP), extending the research to include some additional factors, such as environmental tax, research and development expenditure, implicit tax rate on energy, primary production of coal and lignite, energy intensity of the economy taken from the Eurostat database. The EKC indicates that, at the early stages of economic growth, pollution increases with the growing use of resources, but when a certain level of income per capita is reached, the trend reverses so that, at a higher development stage, further economic growth leads to the improvement of the environment. In the first part of the research, the validity of the reduced EKC for the Baltic region for the period 1995-2008 is determined. In the second part, the impact of selected factors is statistically tested. In both cases, the standard cubic equation is used because it is believed that this model is the most accurate for the development stage of this region. The research results may be useful for climate change policy design.

  6. Energy Policy in the Baltics: A Study of Regional Cooperation

    Science.gov (United States)

    Parks, Jessica Annette

    Regionalism, especially in the form of macro-regions, has emerged as a force of cooperation and integration within the European Union. The Baltic states, who have cooperated more closely since acceding to the EU, provide an effective case study for testing the unifying power of regionalism. As small states that have shared a damaging dependence on Russian energy imports, the three Baltic states share the incentive to cooperate as a region and develop their internal gas, oil, and electricity capacities. The Baltic states have displayed uneven tendencies of cooperation when it comes to energy, however. After presenting an overview of regionalism in the EU, this paper examines EU policy regarding energy in the Baltics, energy ties between the Baltics and other countries, and specific energy projects in the Baltics to show that while the Baltics do not yet have a strong tradition of cooperation in the energy sector, they have laid the groundwork to strengthen future ties.

    Medication-related osteonecrosis of the jaws (MRONJ) is a severe side effect of antiresorptive or antiangiogenic therapy that manifests as an exposed bone, accompanied by clinical signs of infection, persisting for more than 8 weeks, without history of radiation therapy or metastases to the jaws. The aim of the study was to present first MRONJ cases in Lithuania and review trends in the modern research literature on the subject. We retrospectively reviewed patient charts with a diagnosis of "Inflammatory conditions of the jaws" treated in Vilnius University Hospital Žalgiris Clinic, Department of maxillofacial surgery in 2007-2014. Patients diagnosed with MRONJ were selected for the study. Demographic data, characteristics of the disease and treatment modalities were analysed. Nine cases (five male and four female) of MRONJ were analysed. The mean patient age was 69±7,9 years. Predominant primary malignancy was prostate cancer. Osteonecrotic lesions were located both in maxilla and mandible. In all cases we started with a conservative treatment first. After the antibiotic therapy with or without sequestrectomy, the condition of all patients stabilized and improved to stage I MRONJ. MRONJ is a disturbing condition resulting in a severely worsened quality of life in the affected patients. This is the first case series of successfully treated patients suffering from stage II or III MRONJ in the Baltic States. A more comprehensive understanding of MRONJ will hopefully allow clinicians to enhance accuracy in risk assessment and forecast positive and negative outcomes of antiresorptive or antiangiogenic therapy.

  8. Modern Hanseatic Trends in the Baltic Region

    2017-06-01

    Full Text Available A critical analysis of Hanseatic traditions may produce consequential methodological material for the study of the 21st century Baltic regionalisation. Current trends in the development of the Baltic region, whose academic analysis is impossible without considering earlier cases of successful interactions between the peoples of the Baltic Sea region, necessitate political, economic, and historical research on the strengths and weaknesses of the Hanseatic League. Unfortunately, in the 21st century, the Baltic region turned into a stage for geopolitical controversies. This took a toll on the efficiency of cooperation between the cities of Russia’s North-West and their Baltic counterparts. Therefore, it is important to seize the opportunities provided by the information society and focus on the innovative areas of regional cooperation. An interesting example is the partnership between Baltic universities, which is aimed to draw up an international agenda for sustainable regional development. Baltic cities are involved in various forms of cross-border cooperation, providing opportunities for interstate relations and contributes to laying down crossborder cooperation roadmaps and developing civil society networks. It can be concluded, that the history of the Hanseatic League and its current incarnation — the New Hanse — testify to the fact that productive economic, cultural, and other relations can be established between states but also between cities and universities, thus contributing to closer economic, political and cultural ties between the peoples of the Baltic region.

  9. The Role of Government in Restoring International Competitiveness: the Case of Crisis Management in the Baltic States Economies versus Poland Economies

    Directory of Open Access Journals (Sweden)

    Anna Matysek-Jędrych

    2014-03-01

    Full Text Available This paper focuses on the relationship between the government actions, global economic crisis, and competitiveness on a national and regional dimension. The Baltic States (i.e., Estonia, Latvia, and Lithuania have experienced one of the biggest Gross Domestic Product (GDP contractions during the Global Crisis so far. Meanwhile, Poland was the only country with a positive GDP growth in the European Union during the Global Crisis. Hence, identifying and assessing changes in the relative competitiveness, as a consequence of the economic downturn in both Baltic States and Poland, has sparked many interests.The main channel through which the crisis undermined competitiveness has been the macroeconomic situation. That is why employing single macroeconomic variables as proxies of competitiveness suggests a much stronger influence of the crisis on competitiveness in comparison to overall measures (e.g. Global Competitiveness Index. It may be generally concluded that a short-term crisis, even if severe, does not have a negative influence on international competitiveness as long as a proper anti-crisis policy is implemented and the country is small enough to react fast and adapt to new conditions in the global environment.

Thus, many experts noted that the successful lobbying can change the state of the social environment and the socio-political relations. When both unsuccessful lobbying ends

  12. The EU’s rule of law promotion in post-Soviet Europe: what explains the divergence between Baltic States and EaP countries?

    Directory of Open Access Journals (Sweden)

    Martin MENDELSKI

    2016-12-01

    Full Text Available The European Union (EU and domestic “change agents” have promoted the rule of law in post-Soviet Europe with varying results. While the Baltic States (Estonia, Latvia, Lithuania succeeded in establishing the rule of law, Eastern Partnership (EaP countries (Ukraine, Moldova, Georgia, Azerbaijan and Armenia did not. Why did EU-driven legal, judicial and anti-corruption reforms not produce the rule of law in the latter group? I argue that divided elites (reformers in laggard EaP countries engage in detrimental political competition that creates incentives to misuse the law, the prosecution and judicial structures as “political weapons”. The result of this power struggle is an erratic reform process which produces reform pathologies of Europeanization (e.g. legal instability and incoherence, reinforced fragmentation and politicization that undermine the rule of law. Instead of serving as an external check on rule-of-law abusing reformers, the EU empowers reformist but unaccountable “change agents” in a partisan way, thus creating incentives for the accumulation and abuse of power, especially after regime changes. Reformers in the advanced Baltic States have avoided detrimental political competition, the fragmentation of the state and many reform pitfalls through de facto exclusion of ethnic Russians from the political and judicial system. This policy of partial exclusion allowed elites in Estonia and Latvia to build consensus, to create a unitary state, including strong, unified and independent horizontal accountability structures (e.g. judiciary, Ombudsman, Constitutional Court etc. which in turn were able to check the executive. The argument is supported by an empirical, indicator-based analysis of the rule of law and several interviews with representatives in Brussels, Strasbourg and Chisinau.

  13. Upsurge of tick-borne encephalitis in the Baltic States at the time of political transition, independent of changes in public health practices.

    2009-01-01

    Despite evidence that socio-economic factors associated with political transition played a major causal role in the abrupt upsurge in tick-borne encephalitis (TBE) in the newly independent Baltic States, doubts are still repeatedly expressed about the importance of these factors relative to changes in public health practices that may have affected merely the registration of cases. In response to these doubts, evidence of relevant practices of surveillance, registration, diagnosis, awareness and immunization is presented as taken from archived data and interviews with experienced medical practitioners. There were changes that could have had neutral, negative or positive impacts on recorded TBE incidence, but the variable timing in these changes at both national and regional levels is not consistent with their having been responsible for the epidemiological patterns observed in the early 1990 s.

  19. The Baltic policy of Germany and current international relations

    2016-03-01

    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.

    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.

  1. 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.

    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.

    Three Baltic states, Estonia, Latvia and Lithuania are located on the Eastern shore of the Baltic Sea and to North-West of the newly independent states of the former Soviet Union. The Baltic States were part of the SU for many years and consequently a part of a highly structured and centralised system. Prior to gaining independence in 1991, Baltic's power system had been planned and operated as a part of the North -West Interconnected Power Systems (Ips) of the former SU for 30 years. That is why the power systems of individual countries of the Baltic were not planned or operated as a independent systems but regionally, with the planning based on the optimisation of the whole Nord-West interconnected system. The Nord-West IPS included the power systems of Estonia, Latvia, Lithuania, and Belarus, as well as six North-West regions of Russia: Leningrad, Kola Peninsula, Karelia, Pskov, Novgorod, and Kaliningrad. Analysis of the structure, conditions, loads, specifics technical features, basics operation data of the main power stations in the Baltic IPS is given

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.

  9. South Baltic Wind Atlas

    DEFF Research Database (Denmark)

    Pena Diaz, Alfredo; Hahmann, Andrea N.; Hasager, Charlotte Bay

    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 longterm wind statistics using the NCAR-NCEP reanalysis data were performed during 30 years to provide basis for a long-term adjustment of the results and the final WRF results include a weighting...... for the long-term trends variability in the South Baltic Sea. Observations from Earth observing satellites were used to evaluate the spatial resolution of the WRF model results near the surface. The QuikSCAT and the WRF results compared well whereas the Envisat ASAR mean wind map showed some variation...

    2015-08-01

    Full Text Available Against the backdrop of the lingering Ukraine crisis, Russia retaliated against the EU sanctions imposed on selected Russian enterprises and representatives by boycotting import goods from European and North American suppliers. Russian politicians further threatened to restrict the export of raw materials, especially natural gas, provided that the EU-Russia relations further worsen and sanctions gather momen-tum. Hence, the paper deals with the question to what extent the EU economies Estonia, Latvia and Lithuania are vulnerable to Russian reprisals and would experience comparatively high costs of the EU sanction policy. The focus of the analysis is on the Baltic States’ trade relations with Russia because these countries were integrated in the Soviet division of labor before regaining independence. It is analyzed whether path dependencies in Baltic trade patterns still exist that could make Estonia, Latvia and Lithuania more vulnerable to political blackmail than other EU countries.

    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

  14. The Baltic states should adopt the self-defence pinpricks doctrine: the “accumulation of events” threshold as a deterrent to Russian hybrid warfare

    Directory of Open Access Journals (Sweden)

    Nader Philippe Bou

    2017-06-01

    Full Text Available This article addresses a key legal debate that the Baltic NATO members ought to engage in: what constitutes an “armed attack” and what interpretation should be made of this concept in order to deter recent Russian hybrid warfare strategies. These questions are considered in connection with a more general issue regarding the law of self-defence: the question of what constitutes an armed attack in international law. This article will try to present a broad definition and context of Russian hybrid warfare and how it is challenging traditional jus ad bellum paradigms. Too few policy-makers have paid detailed attention to the new Russian “lawfare” in Ukraine, using specific military and non-military tactics in order to blur the lines between “armed attack” and mere political intervention. Meanwhile, legal scholars detach their analysis from actual policy-serving considerations and tend to acquiesce to some very restrictive theories of the use force in self-defence. For some countries, like the Baltic ones, facing strategic exposure – because of both threatening neighbours and low military capacities – the jus ad bellum paradigm should not be construed as another layer of obstacle.

    1999-07-01

    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.

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

    Directory of Open Access Journals (Sweden)

    2013-06-01

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

    Full Text Available Along with rising awareness of public and scientific societies about environmental and ecological impacts of underwater noise, the need for underwater noise modelling in the shallow Lithuanian area of Baltic Sea emerged. Marine Strategy Framework Directive issues regarding underwater noise indicators refers to possibility of evaluation of Good Environmental State using underwater noise measurements as well as possibility to model underwater noise. Main anthropogenic underwater noise contributor in the Seas is the shipping lanes as known due to date, with no exclusion of Lithuanian Baltic Sea area. In this manuscript, it is presented the methods of development of simplistic underwater ambient noise model purposed for computation of underwater soundscape in shallow area of the Lithuanian Baltic Sea.

    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.

  4. Pollution in the Baltic Sea.

    1998-07-01

    The Baltic Sea is almost totally surrounded by land and therefore more endangered by pollution than other marine areas. The sources of marine pollution are municipal and industrial waste inputs directly into the sea or via rivers, and atmospheric inputs mainly from traffic and agriculture. The increase of inorganic plant nutrients (NH3, NOx, PO4) caused eutrophication and consequent oxygen depletion in coastal bottom waters as well as in the depths of the open sea. In the anoxic sediments, hydrogen sulfide can be produced by protein-decomposing and sulfate-reducing bacteria. The bottom fauna will be destroyed and only H2S tolerant microorganisms can survive. Originating from cellulose manufacturing and from paper mills, large amounts of poisonous chlorinated compounds contaminated the coastal waters of Sweden and Finland until the 1980s. Most of this material is still present in sediments of the central Baltic Sea and can be resuspended by near bottom currents. To reduce pollution and improve the situation in the Baltic Sea, the surrounding countries organized the Helsinki Convention, which came into force on 3.5.1980. The Helsinki Commission (HELCOM) founded in 1974 acts as coordinator and is responsible for the enforcement of the Baltic monitoring program and international research projects. The activities of HELCOM have led to the reduction of dangerous pollutants which in turn has caused the regeneration of flora and fauna in some areas. Further improvements can be expected.

    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

    Directory of Open Access Journals (Sweden)

    Viljar Veebel

    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.

    BACKGROUND AND OBJECTIVE. A constant gap has appeared in infant mortality among the 3 Baltic States - Latvia, Estonia, and Lithuania - since the restoration of independence in 1991. The aim of the study was to compare infant mortality rates in all the 3 Baltic countries and examine some of the macro- and socioeconomic factors associated with infant mortality. MATERIAL AND METHODS. The data were obtained from international databases, such as World Health Organization and EUROSTAT, and the national statistical databases of the Baltic States. The time series data sets (1996-2010) were used in the regression and correlation analysis. RESULTS. In all the 3 Baltic States, a strong and significant correlation was found: Latvia (r=-0.81, PLatvia (r=-0.81, PLatvia (r=0.87, PLatvia are apparently explained by less successful adaptation to a new political and economic situation and limited skills in adjusting the healthcare system to the reality of life.

    Preussen Elektra has been researching the possibilities for enhanced cooperation in the Baltic area. The Baltic states; Latvia, Lithuania and Estonia, together with the Russian enclave of Kaliningrad were reliant on energy imports from Russia. The main local resource is oil shale in Estonia, although wood and peat have also been used on a smaller scale. Latvia has hydroelectricity, while Lithuania has a nuclear power plant at Ignalina and a masut oil-fired plant at Elektreinai. Kaliningrad relies on energy imports from Lithuania or St Petersburg. Natural gas is a possible future fuel, but will have to be imported from Russia, the very situation from which the Baltic states wish to escape. Imported coal could be used in power plants - these would need to be constructed as West/East joint ventures. Alternatively electricity could be imported direct from States in the western Baltic, at least a Baltic Ring should be started on, but the problems of transformation from a command economy should not be underestimated

    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.

    Barz, M.; Ahlhaus, M. (eds.)

    2006-07-01

    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

  20. 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.

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

    Directory of Open Access Journals (Sweden)

    Boyd Jonathan A.

    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.

    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.

  3. Solar radiation in the Baltic Sea

    Directory of Open Access Journals (Sweden)

    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.

  7. Scaling the Baltic Sea environment

    DEFF Research Database (Denmark)

    Larsen, Henrik Gutzon

    2008-01-01

    The Baltic Sea environment has since the early 1970s passed through several phases of spatial objectification in which the ostensibly well-defined semi-enclosed sea has been framed and reframed as a geographical object for intergovernmental environmental politics. Based on a historical analysis......-scientific logic, but should rather be seen as temporal outcomes of scale framing processes, processes that are accentuated by contemporary conceptions of the environment (or nature) in terms of multi-scalar ecosystems. This has implications for how an environmental concern is perceived and politically addressed....... of this development, this article suggests that environmental politics critically depend on the delineation of relatively bounded spaces that identify and situate particular environmental concerns as spatial objects for politics. These spaces are not simply determined by ‘nature' or some environmental...

    2015-06-01

    Full Text Available Shipping activities, oil production and transport in the sea, oil handled in harbors, construction and exploitation of offshore oil and gas pipelines have a number of negative impacts on the marine environment and coastal zone of the seas. In 2004-2014 we elaborated several operational satellite monitoring systems for oil and gas companies in Russia and performed integrated satellite monitoring of the ecological state of coastal waters in the Baltic, Black, Caspian, and Kara seas, which included observation of oil pollution, suspended matter, and algae bloom at a fully operational mode. These monitoring systems differ from the existing ones by the analysis of a wide spectrum of satellite, meteorological and oceanographic data, as well as by a numerical modeling of oil spill transformation and transport in real weather conditions. Our experience in the Baltic Sea includes: (1 integrated satellite monitoring of oil production at the LUKOIL-KMN Ltd. D-6 oil rig in the Southeastern Baltic Sea (Kravtsovskoe oil field in 2004-2014; (2 integrated satellite monitoring of the “Nord Stream” underwater gas pipeline construction and exploitation in the Gulf of Finland (2010-2013; (3 numerical modeling of risks of oil pollution caused by shipping along the main maritime shipping routes in the Gulf of Finland, the Baltic Proper, and in the Southeastern Baltic Sea; (4 numerical modeling of risks of oil pollution caused by oil production at D-6 oil rig and oil transportation on shore via the connecting underwater oil pipeline.

  9. The Baltic Sea - an example of how to protect marine coastal ecosystems

    Directory of Open Access Journals (Sweden)

    Dietwart Nehring

    2001-03-01

    Full Text Available The Baltic Sea covers an area of 415 000 km2. A typical brackish sea, it is very sensitive to anthropogenic activities. Inorganic nutrients, trace metals, chlorinated hydrocarbons and crude oil products are contaminants studied in the Baltic Monitoring Programme of HELCOM. The data collected by the riparian countries forms the basis for the periodic assessments of the state of the marine environment of the Baltic Sea Area produced by HELCOM every five years. Since 1992 marine nature conservation has been part of the HELCOM convention. According to the third status report issued in 1996, it was the first time that HELCOM could strike a positive balance with regard to the decreasing environmental load. This is also reflected in lower concentrations of harmful substances in fish, marine mammals and seabirds in the Baltic Sea Area. The reasons for this progress are the protective actions initiated by HELCOM and the economic collapse in some of the former East Bloc countries, the latter resulting in an abrupt fall in industrial and agricultural production. Although the restoration of the Baltic ecosystem has only just begun, the protective measures introduced to achieve this aim can serve as an example of how to solve similar problems in other semi-enclosed basins and shelf seas.

    Directory of Open Access Journals (Sweden)

    Zverev Yuri

    2013-01-01

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

  11. 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.

  12. 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)

  13. Innovative economy in the Baltic Sea region

    Directory of Open Access Journals (Sweden)

    Mezhevich Nikolay

    2012-03-01

    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.

    Directory of Open Access Journals (Sweden)

    Kretinin Gennady

    2013-06-01

    Full Text Available This article focuses on the development of peaceful nuclear power. The author draws attention to the fact that nuclear power is a rather young branch of national economy. However, over recent decades, it has already seen rises and falls, and a number of states have had tragic experiences of nuclear emergencies. Nevertheless, many countries — including the three Baltic States of Estonia, Latvia and Lithuania — express a strong interest in development, generation, and application of nuclear power. In the Baltic States, nuclear power dates back to the Soviet times, but its development was suspended pursuant to the EU regulations (the Ignalina NPP. Lithuania, Latvia, and Estonia have been striving for energy independence from Russia — the principal supplier of energy carriers to these countries. For a long time, the three Baltic States have been proclaiming their unanimity on the general European path of development. However, the reality proved to be different. The touchstone for achieving common goals was the idea of constructing a new NPP at the site of the closed Ignalina NPP. The author concludes that the joint construction of a new NPP is quite questionable. When it comes to politics, each of the three Baltic States is ready to build its own NPP. Thus, the development of nuclear power in the Baltic Sea region requires joint coordinated actions independent of any bloc-inspired interests of the states involved. Moreover, this success may prove sustainable if the actions are based on innovative decisions and modern technologies.

    2015-01-06

    The fossil record of carnivorous plants is very scarce and macrofossil evidence has been restricted to seeds of the extant aquatic genus Aldrovanda of the Droseraceae family. No case of carnivorous plant traps has so far been reported from the fossil record. Here, we present two angiosperm leaves enclosed in a piece of Eocene Baltic amber that share relevant morphological features with extant Roridulaceae, a carnivorous plant family that is today endemic to the Cape flora of South Africa. Modern Roridula species are unique among carnivorous plants as they digest prey in a complex mutualistic association in which the prey-derived nutrient uptake depends on heteropteran insects. As in extant Roridula, the fossil leaves possess two types of plant trichomes, including unicellular hairs and five size classes of multicellular stalked glands (or tentacles) with an apical pore. The apices of the narrow and perfectly tapered fossil leaves end in a single tentacle, as in both modern Roridula species. The glandular hairs of the fossils are restricted to the leaf margins and to the abaxial lamina, as in extant Roridula gorgonias. Our discovery supports current molecular age estimates for Roridulaceae and suggests a wide Eocene distribution of roridulid plants.

    2001-03-01

    Full Text Available The nodal tide in the Baltic Sea was studied on the basis of the Stockholm tide-gauge readings for 1825-1984; data from the tide gauge at Swinoujscie for the same period provided comparative material. The Stockholm readings are highly accurate and are considered representative of sea levels in the whole Baltic; hence, the final computations were performed for the readings from this particular tide gauge for the period 1888-1980. The tidal amplitude obtained from measurements uncorrected for atmospheric pressure or wind field was compared with that forced only by atmospheric effects. The amplitude of the recorded nodal tide was the same as the equilibrium tide amplitude calculated for Stockholm. Calculations for equilibrium tide amplitudes were also performed for the extreme latitudes of the Baltic basin.

  2. Chitinozoan diversity in the East Baltic Silurian

    Directory of Open Access Journals (Sweden)

    Nestor, Viiu

    2009-12-01

    Full Text Available Data on the diversity of the East Baltic Silurian chitinozoans have been compared to global chitinozoan biozones that are approximately correlated with the graptolite scale. The total diversity and balanced total diversity curves have three main positive peaks in the Wenlock and Ludlow and diversity lowstands in most of the Llandovery and Pridoli. The turnover ratio and species origination curves are lowest and species extinction is highest in the lower Wenlock, correlating partly with the Ireviken Event. Chitinozoan diversity is related to the transgression–regression phases of the Silurian Baltic basin, water chemistry and temperature, and evolutionary processes of the faunal group. At the level of the Silurian standard stages the trends in the East Baltic and Swedish chitinozoan diversity curves are in general outline similar to the global diversity curve.

    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.

  8. Baltic Factor in Russia-France Relations

    Maltsev Leonid A.

    2016-12-01

    Full Text Available The article aims to identify the role of the Baltic factor in Russia-France relations. Despite the fact that the Baltic Sea region (BSR no longer plays an important role in Russia-France bilateral relations, the authors attach significance to analysing the dynamics and changes of the BSR role in European politics in the post- Napoleonic period. The authors compare the Russian and the July Monarchies (1830—1848 in the context of the current Vienna system of international relations. The article describes the role of the 1830—1831 uprising in Poland, which was an event of particular importance. The monarchies of the two countries had to take into account new social phenomena, which were more pronounced in France. After the suppression of the uprising in the Polish part of the Russian Empire, Polish emigrants residing in France became the stumbling block for the development of Russia- France relations. The article explores the role of P. de Barante, Ambassador of France to Russia and describes France and Russia’s trade and economic interests in the Baltic Sea region. The authors conclude that the specificity of Russia-France bilateral relations became more apparent during the First and Second World Wars. However, the Baltic factor has lost its relevance over time.

    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)

    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.

    Estuarine macroalgae are important primary producers in aquatic ecosystems, and often foundation species providing structurally complex habitat. Climate change alters many abiotic factors that affect their long-term persistence and distribution. Here, we review the existing scientific literature on the tolerance of key macroalgal species in the Baltic Sea, the world's largest brackish water body. Elevated temperature is expected to intensify coastal eutrophication, further promoting growth of opportunistic, filamentous species, especially green algae, which are often species associated with intensive filamentous algal blooms. Declining salinities will push the distributions of marine species towards south, which may alter the Baltic Sea community compositions towards a more limnic state. Together with increasing eutrophication trends this may cause losses in marine-originating foundation species such as Fucus, causing severe biodiversity impacts. Experimental results on ocean acidification effects on macroalgae are mixed, with only few studies conducted in the Baltic Sea. We conclude that climate change can alter the structure and functioning of macroalgal ecosystems especially in the northern Baltic coastal areas, and can potentially act synergistically with eutrophication. We briefly discuss potential adaptation measures.

    The Baltic Sea provides benefits to all of the nine nations along its coastline, with some 85 million people living within the catchment area. Achieving improvements in water quality requires international cooperation. The likelihood of effective cooperation is known to depend on the distribution across countries of the benefits and costs of actions needed to improve water quality. In this paper, we estimate the benefits associated with recreational use of the Baltic Sea in current environmental conditions using a travel cost approach, based on data from a large, standardized survey of households in each of the 9 Baltic Sea states. Both the probability of engaging in recreation (participation) and the number of visits people make are modeled. A large variation in the number of trips and the extent of participation is found, along with large differences in current annual economic benefits from Baltic Sea recreation. The total annual recreation benefits are close to 15 billion EUR. Under a water quality improvement scenario, the proportional increases in benefits range from 7 to 18% of the current annual benefits across countries. Depending on how the costs of actions are distributed, this could imply difficulties in achieving more international cooperation to achieve such improvements. Copyright © 2015 Elsevier Ltd.

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

    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.

    The contamination of the Baltic Sea with polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) has resulted in restrictions on the marketing and consumption of Baltic Sea fish, making this a priority environmental issue in the European Union. To date there is no consensus on the relative importance of different sources of PCDD/Fs to the Baltic Sea, and hence no consensus on how to address this issue. In this work we synthesized the available information to create a PCDD/F budget for the Baltic Sea, focusing on the two largest basins, the Bothnian Sea and the Baltic Proper. The non-steady state multimedia fate and transport model POPCYCLING-Baltic was employed, using recent data for PCDD/F concentrations in air and sediment as boundary conditions. The PCDD/F concentrations in water predicted by the model were in good agreement with recent measurements. The budget demonstrated that atmospheric deposition was the dominant source of PCDD/Fs to the basins as a whole. This conclusion was supported by a statistical comparison of the PCDD/F congener patterns in surface sediments from accumulation bottoms with the patterns in ambient air, bulk atmospheric deposition, and a range of potential industrial sources. Prospective model simulations indicated that the PCDD/F concentrations in the water column will continue to decrease in the coming years due to the slow response of the Baltic Sea system to falling PCDD/F inputs in the last decades, but that the decrease would be more pronounced if ambient air concentrations were to drop further in the future, for instance as a result of reduced emissions. The study illustrates the usefulness of using monitoring data and multimedia models in an integrated fashion to address complex organic contaminant issues.

  18. Indicator Properties of Baltic Zooplankton for Classification of Environmental Status within Marine Strategy Framework Directive.

    Full Text Available The European Marine Strategy Framework Directive requires the EU Member States to estimate the level of anthropogenic impacts on their marine systems using 11 Descriptors. Assessing food web response to altered habitats is addressed by Descriptor 4 and its indicators, which are being developed for regional seas. However, the development of simple foodweb indicators able to assess the health of ecologically diverse, spatially variable and complex interactions is challenging. Zooplankton is a key element in marine foodwebs and thus comprise an important part of overall ecosystem health. Here, we review work on zooplankton indicator development using long-term data sets across the Baltic Sea and report the main findings. A suite of zooplankton community metrics were evaluated as putative ecological indicators that track community state in relation to Good Environmental Status (GES criteria with regard to eutrophication and fish feeding conditions in the Baltic Sea. On the basis of an operational definition of GES, we propose mean body mass of zooplankton in the community in combination with zooplankton stock measured as either abundance or biomass to be applicable as an integrated indicator that could be used within the Descriptor 4 in the Baltic Sea. These metrics performed best in predicting zooplankton being in-GES when considering all datasets evaluated. However, some other metrics, such as copepod biomass, the contribution of copepods to the total zooplankton biomass or biomass-based Cladocera: Copepoda ratio, were equally reliable or even superior in certain basin-specific assessments. Our evaluation suggests that in several basins of the Baltic Sea, zooplankton communities currently appear to be out-of-GES, being comprised by smaller zooplankters and having lower total abundance or biomass compared to the communities during the reference conditions; however, the changes in the taxonomic structure underlying these trends vary widely across

  3. Modelling Potential Consequences of Different Geo-Engineering Treatments for the Baltic Sea Ecosystem

    Schrum, C.; Daewel, U.

    2017-12-01

    From 1950 onwards, the Baltic Sea ecosystem suffered increasingly from eutrophication. The most obvious reason for the eutrophication is the huge amount of nutrients (nitrogen and phosphorus) reaching the Baltic Sea from human activities. However, although nutrient loads have been decreasing since 1980, the hypoxic areas have not decreased accordingly. Thus, geo-engineering projects were discussed and evaluated to artificially ventilate the Baltic Sea deep water and suppress nutrient release from the sediments. Here, we aim at understanding the consequences of proposed geo-engineering projects in the Baltic Sea using long-term scenario modelling. For that purpose, we utilize a 3d coupled ecosystem model ECOSMO E2E, a novel NPZD-Fish model approach that resolves hydrodynamics, biogeochemical cycling and lower and higher trophic level dynamics. We performed scenario modelling that consider proposed geo-engineering projects such as artificial ventilation of Baltic Sea deep waters and phosphorus binding in sediments with polyaluminium chlorides. The model indicates that deep-water ventilation indeed suppresses phosphorus release in the first 1-4 years of treatment. Thereafter macrobenthos repopulates the formerly anoxic bottom regions and nutrients are increasingly recycled in the food web. Consequently, overall system productivity and fish biomass increases and toxic algae blooms decrease. However, deep-water ventilation has no long-lasting effect on the ecosystem: soon after completion of the ventilation process, the system turns back into its original state. Artificial phosphorus binding in sediments in contrast decreases overall ecosystem productivity through permanent removal of phosphorus. As expected it decreases bacterial production and toxic algae blooms, but it also decreases fish production substantially. Contrastingly to deep water ventilation, artificial phosphorus binding show a long-lasting effect over decades after termination of the treatment.

    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.

    A new method for classifying soft-bottom zoobenthic assemblages along the Finnish coasts (northern Baltic Sea) is presented and tested against traditional physicochemical monitoring data in the complex Archipelago Sea. Although multivariate methods for assessing the state of the marine environment have become widely used, few numerical indices can operate over a wide salinity range. We compare indices currently in use and propose a new index, BBI (brackish water benthic index), for the low-saline and species-poor Baltic coastal waters. BBI offers a salinity-corrected tool for classification of the soft-bottom zoobenthos under the demands of the European Union Water Framework Directive.

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

    The brackish Baltic Sea and the deeper anoxic basins in the central parts are occasionally ventilated by the intrusion of high saline and oxygen rich water from the North Atlantic entering the Baltic Sea. With a volume of 198 km3 containing 4 Gt salt, the inflow event in 2014 was the third largest ever observed. As a result the redox conditions in the anoxic parts of the Baltic Sea changed. In the Bornholm Basin and the Gotland Deep area the biogeochemical conditions for many elements and redox sensitive substances changed crucial by the inflow water. Oxidation of the hydrogen sulfide and consequent changes in the pH and the carbonate system were observed. Other chemicals such as the nitrogen nutrients, phosphate, trace metals and the dissolved organic matter react with the fresh inflow water ingredients. The chronological sequence of the biogeochemical reactions following the inflow event where monitored by autonomous stations and several ship expeditions in high spatial and temporal resolution.

    We present a multi-model ensemble study for the Baltic Sea, and investigate the combined impact of changing climate, external nutrient supply, and fisheries on the marine ecosystem. The applied regional climate system model contains state-of-the-art component models for the atmosphere, sea ice, ocean, land surface, terrestrial and marine biogeochemistry, and marine food-web. Time-dependent scenario simulations for the period 1960-2100 are performed and uncertainties of future projections are estimated. In addition, reconstructions since 1850 are carried out to evaluate the models sensitivity to external stressors on long time scales. Information from scenario simulations are used to support decision-makers and stakeholders and to raise awareness of climate change, environmental problems, and possible abatement strategies among the general public using geovisualization. It is concluded that the study results are relevant for the Baltic Sea Action Plan of the Helsinki Commission.

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

    Tuuling, Igor; Flodén, Tom

    2016-06-01

    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

  2. Innovations in the Baltic Sea Region and Network Cooperation between Russia and the EU

    Full Text Available Transnational (involving countries and cross-border (involving adjacent regions of different countries cooperation and integration are rapidly developing in the Baltic Sea region. Russia lags behind the Nordic countries and Germany as far as innovative development is concerned; yet our national pace here is comparable to that of Poland and the three Baltic States. At the same time, the features of innovative cooperation vary a great deal depending on the group of countries involved in cooperation processes. Independent of its type, however, international cooperation is beneficial for all parties concerned and should therefore be more actively encouraged. Northwestern Federal District traditionally plays a special role in the development of EU-Russia cooperation, since a number of its regions border on the EU countries. The district participates in the development of network innovative structures within the Baltic Sea region. It takes an active part in cross-border cooperation — activities that involve the formation of transborder innovative clusters. There are high expectations associated with the formation of such territorially localised innovative networks, as the Helsinki — Saint Petersburg — Tallinn and Tricity (Gdansk, Gdynia, Sopot — Kaliningrad — Klaipeda transborder innovative clusters. The city of Saint Petersburg and the adjacent Leningrad region, as well as the Kaliningrad region can become innovative development corridors between Russia and the EU and, eventually, develop into the ‘economic growth poles’ of the Russian Federation.

    Full Text Available The main objective of this study is to summarise and analyse the level of scientific interest from researchers from the Baltic Sea Region in interacting with each other on scientific and research projects in university–industry interaction field. This study will use bibliometric analysis based on actual joint initiatives and their published results. The growth of interest from both universities and industry in joint initiatives and changes in the nature of their cooperation (Butcher & Jeffren, 2005 has led to a significant increase in the Baltic Region and the number of scientific publications has doubled in the years 2010–2014. However, compared to the number of similar published studies from the United States, the United Kingdom, China and Japan, those results far outnumber the achievements of the Baltic regions. At the same time, there has been significant increase in the number of studies undertaken by Sweden, Germany and Finland in the period from 2012 to 2014, facilitated by active international and interdisciplinary cooperation and involvement in the research by a large number of authors. The results of the evaluation indicators through this bibliometric analysis can assist in the specific targeting and allocation of available finance and funding into promising fields of research and aid in communication and cooperation between stakeholders and interested organisations.

  4. Security in the Baltic region as a Projection of Global Confrontation between Russia and the USA

    Directory of Open Access Journals (Sweden)

    Vadim Volovoj

    2017-03-01

    Full Text Available This article considers the problem of security in the Baltic region, namely, that of Poland and the Baltics. The authors rely on the works of Karl Deutsch, Emanuel Adler, on Michael Barnett’s theory of security communities and Barry Buzan’s re­gional security complex theory, address Steven Mann’s controlled chaos theory and the concept of Intermarium. Their starting assumption is that the situation in the Baltic depends largely on the politics of external powers — Russia and the United States, — being a projection of their global geopolitical confrontation. The US strategy thus becomes a major part of the equation. The authors believe that since the end of the second Iraq war the American elite has been divided along ideological lines into adherents of the chaos theory and traditionalists thinking in terms of sharing control with the other centres of global power. The US strategy in the Baltic region does not seek an open military conflict with Russia. On the contrary, the US strives to preserve the current level of confrontation between Russia and the EU, convincing the latter of the reality of the Russian threat. Countries that traditionally support confrontation with Russia, Poland and the Bal­tics, serve as a conduit for Washington strategy in Europe and a cordon sanitaire. This function is implemented through the Intermarium project meant to separate Russia from the EU. The four countries are rather active in this area, striving to attain the status of the US principal partners in the region and Europe in general. To retaliate, Moscow does everything within its power to ‘separate’ Brussels from Washington, yet the US influence is still very strong in Europe.

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

    Full Text Available The paper analyses development of the Baltic sovereign CDS market. The level of commonalities and differences in credit risk of the Baltic countries with regard to CDS spreads is investigated. We apply principal component analysis, regression analysis, correlation analysis methods and Granger causality test. Driving forces for changes of CDS spreads in the individual country are established. We discover that the main impact of CDS spread changes arrives from external sources. Our study reveals interdependence between CDS spreads of the Baltic countries and analyses a contagion effect of the change of CDS spreads.

    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.

  10. Coalition Within a Coalition: The Baltics in the European Union

    Directory of Open Access Journals (Sweden)

    Irina M. Busygina

    2017-03-01

    Full Text Available This article gives an overview of small power problem focusing on the behav­iour of small power states within coalitions and their proneness to free riding. 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.

    The salinity influences which ecosystems will dominate in the coastal area and what property radionuclides have. Salinity is also an important boundary condition for the transport models in the geosphere. Knowledge about the past salinity is important background to evaluate the hydrology and geochemistry in the rock and further to assess the radiological consequences of possible releases from a radioactive repository. This report concerns the salinity in the Baltic Sea during the last 8500 calendar years BP. Shore-level data for the inlet areas and proxy (indirect) data for the palaeo-salinity and the climate are reviewed. These data is further used in a steady-state model for the salt exchange between the Baltic Sea and Kattegat. This will then be extended to a model of the future development of the salinity in the Baltic Sea. We conclude that the changes in the inlet cross-section areas together with a 15% to 60% lower net freshwater input compared to the present input can explain the higher salinity in the Baltic Sea during earlier times.

    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.

    Science.gov (United States)

    Fischer, I.; Destouni, G.; Prieto, C.

    2015-12-01

    Changes in climate and land-use have and will continue to modify regional hydrology, in turn impacting environmental health, agricultural productivity and water resource quality and availability. The Baltic region is an area of interest as the coast spans nine countries- serving over 100 million people. The Baltic Sea contains one of the largest human caused hypoxic dead zones due to eutrophication driven by anthropogenic excess loading of nutrients. Policies to reduce these loads include also international directives and agreements, such as the EU Water Framework Directive, adopted in 2000 to protect and improve water quality throughout the European Union, and the Baltic Sea Action Plan under the Helsinki Commission aimed specifically at reducing the nutrient loading to and mitigating the eutrophication of the Baltic Sea. In light of these policies and amidst the number of studies on the Baltic Sea we ask, using the accessible nutrient and discharge data what does nutrient loading look like today? Are the most excessive loads going down? Observed nutrient and flow time series across Sweden allow for answering these questions, by spatial and temporal trend analysis of loads from various parts of Sweden to the Baltic Sea. Analyzing these observed time series in conjunction with the ecological health status classifications of the EU Water Framework Directive, allows in particular for answering the question if the loads into the water bodies with the poorest water quality, and from those to the Baltic Sea, are improving, being maintained or deteriorating. Such insight is required to contribute to relevant and efficient water and nutrient load management. Furthermore, empirically calculating nutrient loads, rather than only modeling, reveals that the water body health classification may not reflect what water bodies actually contribute the heaviest loads to the Baltic Sea. This work also underscores the importance of comprehensive analysis of all available data from

    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

    of the tsarist government, breaking the self-encapsulation of Baltic German cultural circles, etc.  Bulgarin depicts the local Baltic Germans as sincere, naive and emotional children of nature or cold, enlightened sceptics who are critical of Russia. We can see how the latter description becomes more and more dominant in his texts. Thus, following the metaphor of an alarm clock, we can observe the evolution of Bulgarin’s thoughts: after the 1830s the “awaking” is related to conflicts with the local elite, and the alarm clock does not awaken the Baltic Germans any more but, rather, informs the authorities about danger. Bulgarin’s view of the Baltic Germans changes from positive to negative (opposed to the authorities, distrustful, hostile to Russia. As a result, the previously idealised image of Baltic Germans as innocent and sincere is replaced by one describing the locals as lazy, rebellious and amoral people. It is important to notice that the author even points out that besides the Baltic Germans, local students of Russian nationality also oppose the authorities. In this context, the original opposition, Russians – Baltic Germans, is replaced by state supporting – state opposing. To illustrate this point further, the author also mentions how the activities of a Baltic German, a state official Craffström, are useful for the state and support the authorities. Bulgarin’s auto-image undergoes an important, dramatic transformation as well: the initially naive philosopher and poet, the message-bearing angel and political awakener finally becomes a guardian of public order and a fighter against German ways and customs.

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

    Full Text Available This article focuses on the development of peaceful nuclear power. The author draws attention to the fact that nuclear power is a rather young branch of national economy. However, over recent decades, it has already seen rises and falls, and a number of states have had tragic experiences of nuclear emergencies. Nevertheless, many countries — including the three Baltic States of Estonia, Latvia and Lithuania — express a strong interest in development, generation, and application of nuclear power. In the Baltic States, nuclear power dates back to the Soviet times, but its development was suspended pursuant to the EU regulations (the Ignalina NPP. Lithuania, Latvia, and Estonia have been striving for energy independence from Russia — the principal supplier of energy carriers to these countries. For a long time, the three Baltic States have been proclaiming their unanimity on the general European path of development. However, the reality proved to be different. The touchstone for achieving common goals was the idea of constructing a new NPP at the site of the closed Ignalina NPP. The author concludes that the joint construction of a new NPP is quite questionable. When it comes to politics, each of the three Baltic States is ready to build its own NPP. Thus, the development of nuclear power in the Baltic Sea region requires joint coordinated actions independent of any bloc-inspired interests of the states involved. Moreover, this success may prove sustainable if the actions are based on innovative decisions and modern technologies.

  11. Export Promotion Aims and Reality: A Comparison of the Iberian, Baltic and Central European Region

    2017-06-01

    Full Text Available As a consequence of the international crisis in 2008-2009, the role of exports in economic growth came into focus in most countries. Exports of EU Member States gained momentum from 2010 onward but with certain changes in their structure and direction. In several countries, the turn towards non-EU areas, such as China or Latin America was part of the state export strategy. On the one hand, our article describes these foreign trade strategies and their institutional framework of the Iberian, Baltic and Central European governments, detecting possible similarities. On the other hand, we analyse recent export data. This way we can get a picture on the structure and direction of exports of periphery economies and this can be compared to the aims of the given states. Our hypothesis is that there is a gap between the reality and the intentions of the governments. The size of this gap varies and is influenced by certain factors such as the different involvement of multinational companies in foreign trade or the different economic structure of these countries. In our paper we list which countries adopted a government strategy and with what aim. We provide a short literature review on state trade promotion policies and discuss these policies and their institutions in the Baltic, Visegrád and Iberian countries.

    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

    2012-04-01

    Baltic artesian basin (BAB) is a multi-layer sedimentary basin spanning around 480'000 km2. BAB is located in the territory of Latvia, Lithuania and Estonia, parts of Poland, Russia, Belarus and large area of the Baltic Sea, including island of Gotland. The thickness of sedimentary cover is about 5000 m in the south-western part. Crystalline bedding reaches the surface in the northern and north-western parts. The aim of the present work is development of the model of geometric structure and three dimensional finite element mesh for the hydrogeological model of the whole BAB. The information that is used to build the geometrical structure includes: (1) Stratigraphic information from boreholes in Latvia and Estonia (2) Maps of height isolines of geological layers for Latvia and Lithuania (3) Maps of sub-quaternary deposits in Latvia and Lithuania (4) Maps of fault lines on the crystalline basement surface in Latvia, Lithuania and Estonia (5) Buried valley data from Latvia and Estonia (6) Earth topography data (7) Baltic sea depth data (8) Data from published geological cross-sections, information from books and other sources. Unification of the heterogeneous information from different sources, which are employed for building of the geometrical structure of the model are performed. Special algorithms are developed for this purpose considering the priority, importance and plausibility of each of the data sources. Pre-processing of the borehole information to screen out the outlying borehole data has been performed. Model of geological structure contains 42 layers. It includes aquifers and aquitards from Cambrian up to the Quaternary deposits. Fault displacements are incorporated into the model taking into account data from the published structural maps. Four reconstructed regional erosion surfaces (upper Ordovician, Devonian, Permian and Quaternary) are included into the model Three dimensional mesh of the geological structure is constructed layer-wise.

    Full Text Available This article analyses the issues of EU energy policy in the 1990s-the beginning of the 2000s in order to identify the features of energy supply and energy safety of the Baltic region countries. The research and practical significance of the work lies in the stepwise description of actions taken by EU leaders and EU member states in order to formulate a common European energy policy. The 2004 EU enlargement posed the problem of taking into account the features of energy supply of Eastern European countries and, especially, the Baltic States. The energy industries of Lithuania, Latvia, and Estonia, as well as other Eastern European and CIS countries, are closely related to the energy industry of the Russian Federation. Trying to allow for this circumstance, EU leaders and energy structures took a number of organizational measures aimed, on the one hand, at an increase in energy independence of new members of the EU and, on the other hand, at taking into account the recent trends in the energy market development. The research shows that most of the initiatives do not take into account the perspective and interests of Russia, which has a strong presence in the energy market. The analysis conducted will help the assessment of prospects of further development of the Baltic States' energy industry and its interaction with that of the Russian Federation.

    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{sup 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 {sup 137}Cs and {sup 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

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.

    Particulate carbonaceous matter is significant contributor to ambient particulate matter originating from intervening sources which contribution is difficult to quantify due to source diversity, chemical complexity and processes during atmospheric transport. Carbon isotope analysis can be extremely useful in source apportionment of organic matter due to the unique isotopic signatures associated with anthropocentric (fossil fuel), continental (terrestrial plants) and marine sources, and is particularly effective when these sources are mixed (Ceburnis et al., 2011;Ceburnis et al., 2016). We will present the isotope ratio measurement results of aerosol collected during the cruise in the Baltic Sea. Sampling campaign of PM10 and size segregated aerosol particles was performed on the R/V "Oceania" in October 2015. Air mass back trajectories were prevailing both from the continental and marine areas during the sampling period. The total carbon concentration varied from 1 µg/m3 to 8 µg/m3. Two end members (δ13C = -25‰ and δ13C = -28 ‰ ) were established from the total stable carbon isotope analysis in PM10 fraction. δ13C analysis in size segregated aerosol particles revealed δ13C values being highest in the 1 - 2.5 µm range (δ13C = -24.9 ‰ ) during continental transport, while lowest TC δ13C values (δ13C ≈ -27 ‰ ) were detected in the size range D50 marine environment. Additionally, concentration of bacteria and fungi were measured in size segregated and PM10 aerosol fraction. We were able to relate aerosol source δ13C end members with the abundance of bacteria and fungi over Baltic Sea combining air mass trajectories, stable isotope data, fungi and bacteria concentrations.

    River flow to the Baltic Sea originates under a range of different climate regimes in a drainage basin covering some 1,600,000 km{sup 2}. Changes to the climate in the Baltic Basin will not only affect the total amount of freshwater flowing into the sea, but also the distribution of the origin of these flows. Using hydrological modeling, the effects of future climate change on river runoff to the Baltic Sea have been analyzed. Four different climate change scenarios from the Swedish Regional Climate Modelling Programme (SWECLIM) were used. The resulting change to total mean annual river flow to the Baltic Sea ranges from -2% to +15% of present-day flow according to the different climate scenarios. The magnitude of changes within different subregions of the basin varies considerably, with the most severe mean annual changes ranging from -30% to +40%. However, common to all of the scenarios evaluated is a general trend of reduced river flow from the south of the Baltic Basin together with increased river flow from the north.

    2014-03-01

    Full Text Available International cluster is a relatively new form of spatial organisation of economy in the globalisation conditions, which has become a frequent phenomenon in European countries, including those of the Baltic region. It requires a comprehensive study of both regional economics and economic geography. This article aims to identify structured international clusters in the Baltic region and map the corresponding regions. The results obtained will make it possible to get a comprehensive idea of the aggregate of international clusters existing and emerging in the region and put forward a hypothesis about the prerequisites of their formation. The methodological framework of the research is an integrated case study. The article considers the processes of transboundary and transnational regionalisation in the countries of the Baltic region aimed at the development of international clusters. ‘International cluster’ is defined as a new form of spatial economy. The author identifies and maps organised international clusters and cluster initiatives in the Baltic Sea region countries. The international clusters of the Baltic region are characterised according to the following criteria: the degree of geographical localisation, the organisational type of formation, and specialisation areas. The author analyses the degree of involvement of a Russian region into the processes of international cluster cooperation in the macroregion.

    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.)

    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.)

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

  12. 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.

    Full Text Available Baltic countries are located in the limits of the Baltic sedimentary basin, a 700 km long and 500 km wide synclinal structure. The axis of the syneclise plunges to the southwest. In Poland the Precambrian basement occurs at a depth of 5 km. The Baltic Basin includes the Neoproterozoic Ediacaran (Vendian at the base and all Phanerozoic systems. Two aquifers, the lower Devonian and Cambrian reservoirs, meet the basic requirements for CO2 storage. The porosity and permeability of sandstone decrease with depth. The average porosity of Cambrian sandstone at depths of 80–800, 800–1800, and 1800–2300 m is 18.6, 14.2, and 5.5%, respectively. The average permeability is, respectively, 311, 251, and 12 mD. Devonian sandstone has an average porosity of 26% and permeability in the range of 0.5–2 D. Prospective Cambrian structural traps occur only in Latvia. The 16 largest ones have CO2 storage capacity in the range of 2–74 Mt, with total capacity exceeding 400 Mt. The structural trapping is not an option for Lithuania as the uplifts there are too small. Another option is utilization of CO2 for enhanced oil recovery (EOR. The estimated total EOR net volume of CO2 (part of CO2 remaining in the formation in Lithuania is 5.6 Mt. Solubility and mineral trapping are a long-term option. The calculated total solubility trapping capacity of the Cambrian reservoir is as high as 11 Gt of CO2 within the area of the supercritical state of carbon dioxide.

    The report represents the summary of the main factors, which affects the future development and state of the Baltic Sea. The emphasis is on land uplift, shoreline displacement, and physical, chemical and biological characteristics of the sea. In addition, historical evolution of the Baltic Sea after the last ice age and potential impacts of the different climate scenarios are presented. The Baltic Sea has an important influence on the development of the geospherebiosphere interface zone at Olkiluoto. Thus, it is important to take account all these factors in the Safety Modelling of the nuclear waste repository. Different models have been used to evaluate land uplift at Olkiluoto and changes in the sea and land area, especially in the interface zone. The main parameters have been monitored satisfactory way at the Olkiluoto offshore. Based on the present sea sediment stratigraphy, overburden, topography and vegetation it has been fairly well estimated coming future land and sea areas of the Olkiluoto Island and its surroundings. According to the results, Olkiluoto will be part of the continent during the next decade. In the shallow shores of Olkiluoto, the amounts of common reed are increasing naturally, resulting in paludification. The spatial and temporal changes at Olkiluoto can be estimated and modelled more detailed by using the well focused research sites and more accurate results. In addition, more information is needed on development of the watershed areas, lakes, rivers and vegetation and on sedimentation and erosion processes, hydrology, quality and quantity of seabed sediments and stratigraphy, element budgets and recharge and discharge areas, especially at the geosphere-biosphere interface zones.

Also the land-locked, partly anoxic Baltic Sea receives almost as much nitrogen from nitrogen fixation as it receives from eutrophied rivers. Growth conditions for cyanobacteria are usually very favorable with low N/P ratios after...... winter mixing and a strong stratification and high surface temperatures in summer. However, the summer 2012 was quite different with strong winds and cold surface waters. Blooms of cyanobacteria therefore only developed in sheltered regions but not in the central Baltic Proper. Moreover, a greater...

    This study analyses a multispecies (cod, herring and sprat) partition function game among three asymmetric countries in the Baltic Sea. Through an empirical application, the study highlights the importance of dynamic multispecies models in coalition formation. We show that the grand coalition...... between the three countries can be stabilised when the most efficient country compensates the other countries. This solution is not feasible when using a single-species model for the cod population; thus, taking into account the multispecies nature of the Baltic Sea fisheries, the scope of cooperation...

    2017-12-01

    Full Text Available This article considers the current state and prospective development of the amber industry in the Baltic Sea region. The authors identify the main obstacles to the industry’s development in Russia — poor pricing mechanisms for raw amber, an imbalance between supply and demand, a slow pace of technological modernisation, and a delayed introduction of new technologies and processing techniques. The authors identify gaps in the regulatory framework and highlight problems of legal regulation and law enforcement as regards the amber industry. Combating illegal amber extraction and trafficking is a pressing problem in the Kaliningrad region (Russia and other Baltic region states. The article explores theoretical aspects of the legislative policy on combating illegal amber extraction and trafficking. The authors focus on the relevant law enforcement practices and hold that administrative sanctions for unauthorised amber extraction and trade are not fully effective in Russia. The authors stress the need for introducing criminal liability for a repeated offence and outline opportunities for using forensic gemological examination of amber and amber products.

    Lang, Kai-Olaf

    2010-10-15

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

    Full Text Available Between August and September 1991, the Baltic States forced their break with the USSR, just a few months before the latter disintegrated. From that moment on, the recovery of national independence and sovereignty – first established during the inter-war period only to be thwarted by the pact between Germany and the Soviet Union in 1939 – as well as the consolidation of democracy, the rule of law and a market economy, were given impetus by their desire to join the European Union and the North Atlantic Treaty Organization. After more than a decade of major transformations, both political and socio-economic in nature, the three Baltic States – Lithuania, Estonia and Latvia – have successfully achieved the two fundamental prerequisites for a future of peace, liberty, prosperity and security in the twenty-first century: their «return to Europe» as members of the European Union and their link with the Euro-Atlantic military alliance as members of NATO. | Entre agosto y septiembre de 1991, los Países Bálticos forzaron su ruptura con la Unión Soviética, pocos meses antes de que ésta se desintegrara totalmente. A partir de ese momento, la recuperación de su independencia y soberanía nacional -fraguada por primera vez en la época de entreguerras y frustrada por el pacto germano-soviético de 1939-, así como la consolidación de la democracia y el Estado de Derecho y la economía social de mercado, fue de la mano de su aspiración de integración en la Unión Europea y en la Organización del Tratado del Atlántico Norte. Después de más de una década de grandes transformaciones, tanto políticas como socioeconómicas, los tres Países Bálticos -Lituania, Estonia y Letonia- han logrado cumplir con éxito aquellos dos objetivos fundamentales para su futuro en paz, libertad, prosperidad y seguridad en el siglo XXI: el «retorno a Europa» en el marco de la Unión Europea y su vinculazión a la alianza militar euroatlántica dentro de la

    The present state of contamination of bottom sediments in southern part of the Baltic Sea with PCDD/Fs was compared to the findings made for the north-western and eastern Baltic Sea coastal areas of Finland, Sweden and Denmark. The extent of the study area--from marine the Gdańsk Basin, the lower Oder and Vistula Rivers up till Włocławek reservoir--allowed to obtain the sediment samples with diversified properties. Dioxin's concentrations in sediments examined in the Polish costal area allows us to evaluate this zone as relatively less contaminated. Higher dioxin concentration has been found in Wloclawek Dam Reservoir. Differences in congener patterns and temporal changes in marine sediment profiles were examined. The highest concentrations of tetra- and penta-congeners still remain in the surface layer of Gdansk Deep, whereas the decline in concentrations of these most toxic congeners, have been observed in the sediments from some other parts of the Baltic coast. Excess concentration of dioxins in sediments has a great impact on human being due to special ability of accumulation in the trophic chain as well as in water (fishes) and land (milk, meat).

  13. 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. Two centuries of mean Baltic Sea level variability - an overview

    Science.gov (United States)

    Hünicke, Birgit; Zorita, Eduardo; Madsen, Kristine S.; Johannson, Milla

    2015-04-01

    The understanding of the processes which drive future climatic trends of sea-level on global to regional scales presumes the understanding of long-term variability in the observational period. This requires an accurate assessment of past and recent global and regional sea-level changes. Here, we review the observed changes (1800-2000) in mean sea-level variability in the Baltic region and the main (climate) drivers for these changes. We introduce the datasets available for studying sea-level and review the major published findings which can be derived from them. The Baltic is one of the most investigated sea-level sites in the world. It has a remarkable number of long and high quality densely spaced, tide gauge records with many stations in continuous operation since the late 19th century and some of the oldest sea-level records reporting since 200 years. More than 45 stations with at least 60 years of data have continued until recent times. Mean Baltic Sea level changes are dominated by crustal deformations due to the glacio-isostatic land movement effect. The basin-wide pattern of relative sea-level trends shows a clear north-south gradient with a negative rate of -8.2 mm/yr in the Gulf of Bothnia. Thus, RSL is falling in the northern Baltic (where the continental crust is uplifting at roughly 10 mm/yr) and rising in parts of the Southern Baltic. Baltic Sea level changes are affected by a sum of processes. These include thermo and halosteric effects, changes in wind, surface air-pressure and ocean currents, increasing freshwater input and gravitational effects. The decadal sea-level variability around the quasi-linear long-term trend is strongly influenced by westerly winds, closely related to the dominant large-scale sea-level pressure (SLP) pattern of the North Atlantic (NAO). The correlation between sea-level and SLP is highest in winter, but shows significant temporal and spatial heterogeneity with low values in southern Baltic parts. The decadal influence of

    Directory of Open Access Journals (Sweden)

    Bogdan Woźniak

    2011-11-01

    Full Text Available This paper is the second part of the description of the first stage of the SatBałtyk project's implementation. Part 1 (Woźniak et al. 2011, in this issue presents the assumptions and objectives of SatBałtyk and describes the most important stages in the history of our research, which is the foundation of this project. It also discusses the operation and general structure of the SatBałtyk system. Part 2 addresses various aspects of the practical applicability of the SatBałtyk Operational System to Baltic ecosystem monitoring. Examples are given of the Baltic's characteristics estimated using the preliminary versions of the algorithms in this Operational System. At the current stage of research, these algorithms apply mainly to the characteristics of the solar energy influx and the distribution of this energy among the various processes taking place in the atmosphere-sea system, and also to the radiation balance of the sea surface, the irradiance conditions for photosynthesis and the condition of plant communities in the water, sea surface temperature distributions and some other marine phenomena correlated with this temperature. Monitoring results obtained with these preliminary algorithms are exemplified in the form of distribution maps of selected abiotic parameters of the Baltic, as well as structural and functional characteristics of this ecosystem governed by these parameters in the Baltic's many basins. The maps cover practically the whole area of the Baltic Sea. Also given are results of preliminary inspections of the accuracy of the magnitudes shown on the maps. In actual fact, the errors of these estimates are relatively small. The further practical application of this set of algorithms (to be gradually made more specific is therefore entirely justified as the basis of the SatBałtyk system for the effective operational monitoring of the state and functioning of Baltic ecosystems. This article also outlines the plans for extending

    The Argo programme is one of the most important elements of the ocean observing system. Currently almost 4000 Argo floats profile global oceans and deliver real time data. Originally Argo floats were developed for open ocean observations. Therefore a standard float can dive up to 2000 m and deep Argo floats are under development. However in the last years the shallow shelf seas become also interesting for Argo users. Institute of Oceanology Polish Academy of Sciences (IOPAN) participates in the Euro-Argo research infrastructure, the European contribution to Argo system. A legal and governance framework (Euro-Argo ERIC) was set up in May 2014. For a few years IOPAN has deployed floats mostly in the Nordic Seas and the European Arctic region. In the end of 2016 the first Polish Argo float was deployed in the Southern Baltic Sea. Building on the successful experience with Argo floats deployed by the Finnish oceanographers in the Bothnian Sea and Gotland Basin, the IOPAN float was launched in the Bornholm Deep during the fall cruise of IOPAN research vessel Oceania. The standard APEX float equipped with 2-way Iridium communication was used and different modes of operation, required for the specific conditions in the shallow and low saline Baltic Sea, were tested. Settings for the Baltic float are different than for the oceanic mode and were frequently changed during the mission to find the optimum solution. Changing the float parking depth during the mission allows for the limited control of the float drift direction. Results of a high resolution numerical forecast model for the Baltic Sea proved to be a valuable tool for determining the parking depth of the float in the different flow regimes.

    The Baltic Sea is a semi-enclosed brackish sea in Northern Europe with a drainage basin four times larger than the sea itself. Riverine organic carbon (Particulate Organic Carbon, POC and Dissolved Organic Carbon, DOC) dominates carbon input to the Baltic Sea and influences both land-to-sea transport of nutrients and contaminants, and hence the functioning of the coastal ecosystem. The potential impact of future climate change on loads of POC and DOC in the Baltic Sea drainage basin (BSDB) was assessed using a hydrological-biogeochemical model (CSIM). The changes in annual and seasonal concentrations and loads of both POC and DOC by the end of this century were predicted using three climate change scenarios and compared to the current state. In all scenarios, overall increasing DOC loads, but unchanged POC loads, were projected in the north. In the southern part of the BSDB, predicted DOC loads were not significantly changing over time, although POC loads decreased in all scenarios. The magnitude and significance of the trends varied with scenario but the sign (+ or -) of the projected trends for the entire simulation period never conflicted. Results were discussed in detail for the "middle" CO2 emission scenario (business as usual, a1b). On an annual and entire drainage basin scale, the total POC load was projected to decrease by ca 7% under this scenario, mainly due to reduced riverine primary production in the southern parts of the BSDB. The average total DOC load was not predicted to change significantly between years 2010 and 2100 due to counteracting decreasing and increasing trends of DOC loads to the six major sub-basins in the Baltic Sea. However, predicted seasonal total loads of POC and DOC increased significantly by ca 46% and 30% in winter and decreased by 8% and 21% in summer over time, respectively. For POC the change in winter loads was a consequence of increasing soil erosion and a shift in duration of snowfall and onset of the spring flood

    2016-12-01

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

    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.

  4. Public Risk Perceptions towards Oxygenation Pumping in the Baltic Sea

    This report provides the findings of national representative risk perception surveys undertaken in Finland, Lithuania and Sweden during 2011 in rela-tion to oxygenation pumping in the Baltic Sea. The risk perception surveys find that as the scale of pumping increases from small- to large scale......, people are i) more concerned about the potential eco-logical risks and ii) less willing to accept the risks and uncertainties of pumping for the prospects of a faster recovery of the Baltic Sea through pumping. Across several dimensions, the Swedish population appears as the most risk averse...... and the Finnish population as the least risk averse towards potential risks and uncertainties associated with oxygenation pumping. We only find partial evidence that the level of risk (high vs. low risk) is a de-terminant for people’s perceived level of concern. In most cases, respondents show no statistically...

    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...

    Newly hatched Baltic cod Gadus morhua larvae are typically found at depths >60 m. 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....... To lest this hypothesis, Baltic cod larvae were sampled during the spawning seasons of 1994 and 1995 with depth-resolving multiple opening/closing nets. Each larva was aged by otolith readings and its RNA/DNA ratio was determined as a measure of nutritional condition. The RNA/DNA ratios of these larvae...... caught larvae had RNA/DNA ratios between the mean values found for starving and fed laboratory larvae. Only larvae aged 8-11 days had higher mean RNA/DNA ratios above 45 m than below (t-test, P...

    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

    , and concentrations in fish and other fauna are still significant. Several models of the fluxes of these pollutants among the water, sediment, and atmosphere have been developed, but these generally omit the roles of fish and fisheries. We show that the standing stock of the most abundant fish species in the Baltic...... Sea was a sink for 260 kg of PCBs in the late 1980s to early 1990s and that the fishery removed as much or more PCB (31 kg yr(-1)) than other budget components (e.g., degradation in the water column). Accounting for fish and fisheries could increase our understanding of the fluxes of pollutants......The Baltic Sea is heavily polluted yet supports major Commercial fisheries for cod (Gadus morhua), herring (Clupea harengus), and sprat (Sprattus sprattus). Emissions of persistent organic pollutants, such as polychlorinated biphenyls (PCBs) and DDT, were high during the 1960s and 1970s...

    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.

Henry was an eyewitness, even if surely biased......, to many of the events covered in his chronicle, which today is the prime source for our knowledge of this early period of the Baltic crusades, marked as they were by the characteristics of the crusades to these pagan regions: a prolonged forcible process of Christianization and conquest. The other...... chronicle examined in this article is the Chronicon terre Prussie. This chronicle, authored by a Teutonic Knight named Peter of Dusburg and written c.1326, relates the arrival and history of the Teutonic Order in Prussia from c.1230, also covering the initial submission of the Prussian pagans to Christian...

    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.

  14. Light scattering in Baltic crude oil - seawater emulsion

    Full Text Available The paper discusses the scattering of radiation by a Baltic crude oil - seawater emulsion. The scattering spectrum calculated using the Mie solution in the spectral range from 380 nm to 730 nm is compared with the measured spectrum of light scattered through a right angle. Spectra in the wavelength range from 210 nm to 730 nm were measured using a spectrofluorimeter for fresh and stored samples of the Baltic crude oil emulsion. Scattering increases with wavelength in the UV range and then decreases slightly with the wavelength of visible light. The result of the calculation is similar to the measured spectra. Both the calculated and measured spectra display numerous relative extremes throughout the spectral area. Light scattering in the emulsion decreases during storage as the oil concentration in the medium diminishes. The results also demonstrate that the single scattering model describes the phenomenon correctly.

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

  17. 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)

  18. Variability of lithospheric structure in the Baltic Shield

    Pedersen, Helle; Debayle, Eric; Maupin, Valérie

    2013-04-01

    We present the shear velocity structure down to 250km depth beneath the dense LAPNET array in northern Finland, located at the northern end of the Baltic Shield. We analysed phase velocity dispersion of fundamental mode Rayleigh waves, using data from 46 seismic broadband stations and almost 200 magnitude >6 events. The inversion of the dispersion curve shows a well resolved low velocity zone starting at approximately 150km depth, while the shear velocities above are typical for cratonic lithosphere. The comparison to other parts of the Baltic Shield show strong variability of the lithospheric structure. Immediately south of LAPNET, in an area dominated by paleaproterozoic rocks at surface, the lithosphere is fast to a depth of 225-250km, while cratonic lithosphere seems to be absent beneath southern Norway, in spite of Proterozoic age tectonic ages. The low velocity zone beneath northern Finland indicates that the lithosphere in this area is either modified at depth, for example through metasomatism, or that it is thinner than the more internal part of the Baltic shield. We suggest that the modification of the cratonic lithosphere beneath northern Finland is not related to continental breakup at the opening of the Atlantic Ocean, as the continental shelf continues north, beneath the Barents Sea. We rather favour the hypothesis that subduction and/or collision could potentially modify (by fluid injection) or remove (by erosion/dripping) otherwise stable cratonic lithosphere.

    2016-04-01

    A newly developed shallow water model for the Baltic Sea and North Sea is presented. The model is validated by means of a comparison with hindcast simulations with observational data sets. The aim of the development is to provide and apply a modelling tool to model extreme sea levels in the Baltic Sea, Kattegat and Skagerrak. The model approach will support the direct analysis of extreme sea level observations in the past and provide the possibility to extend the statistical data base by producing very long time series or very large ensembles of coastal sea levels. This effort is intended to contribute to an assessment of risks due to storm surges and coastal flooding in the 21st century along the coast of Sweden. By using different RCP climate scenarios downscaled with a regional, coupled climate model atmospheric forcing is available to project possible changes in extreme sea levels into the future. Projected sea level rise, changes in dynamical sea level in the North East Atlantic and tidal forcing in the northern North Sea are applied as boundary condition which allows to investigate their impact on the dynamics of regional sea level variability. Initial experiments focus on the impact of model resolution, resolution in the atmospheric forcing and the amount of details necessary in the bathymetry to faithfully model coastal sea level in the Baltic Sea and North Sea.

  1. Baltic Area - a specific region of climate change

    International Nuclear Information System (INIS)

    Shevkunova, Emma; Mescherskaya, Anna; Jaani, Ago

    1999-01-01

    The article points out that the Baltic Sea area has several specific characters of meteorological regime that makes it remarkably different from other regions in the Northen Hemisphere. First of all, it is caused by the geographical situation of the region - on the connecting area of two opposite atmospheric macro-systems - North-Atlantic ocean and Eurasian continental. The specialities of atmospheric circulation create weather situation that often causes a dissonance between climate changes here and general trends in Eastern and Western Europe in the same periods. On the contrary, in the periods of a general warming in Northern Hemisphere, extremely cold winters may occur in Baltic region. On the basis of the analysis of the data from mid-latitudes in the whole Northern Hemisphere, the main result is that the centre of present warming in the hemisphere is located in the eastern part of Baltic area, between Tallinn and St. Petersburg. A 8-year cycle appears in long time series of annual mean temperature. There is no connection between solar activity and the occurrence of extremely warm and extremely cold winter. The warming during the last 11 years (1988-1998) has been the greatest in this century. The reason of warming is growth of intensity of cyclonic activity in the North Atlantic, and especially, a remarkable increase in frequency of deep cyclones

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

    1992-01-01

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

    2008-11-15

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

    Coastal habitats are situated on the border between land and sea, and ecosystem structure and functioning is influenced by both marine and terrestrial processes. Despite this, most scientific studies and monitoring are conducted either with a terrestrial or an aquatic focus. To address issues concerning climate change impacts in coastal areas, a cross-ecosystem approach is necessary. Since habitats along the Baltic coastlines vary in hydrology, natural geography, and ecology, climate change projections for Baltic shore ecosystems are bound to be highly speculative. Societal responses to climate change in the Baltic coastal ecosystems should have an ecosystem approach and match the biophysical realities of the Baltic Sea area. Knowledge about ecosystem processes and their responses to a changing climate should be integrated within the decision process, both locally and nationally, in order to increase the awareness of, and to prepare for climate change impacts in coastal areas of the Baltic Sea.

    2016-05-01

    The diet of whiting Merlangius merlangus in the western Baltic Sea was investigated and compared to the diet in the southern North Sea. Clupeids were important prey in both areas, but especially in the western Baltic Sea where they constituted up to 90% of the diet of larger individuals. Gobies, brown shrimps and polychaetes were the main prey of juveniles in the western Baltic Sea, while a wider range of species were consumed in the North Sea. The shift to piscivory occurred at smaller sizes in the western Baltic Sea and the fish prey consumed was proportionately larger than in the southern North Sea. Estimates of prey abundance and food intake of M. merlangus are required to evaluate its predatory significance in the western Baltic Sea, but its diet suggests that it could be just as significant a fish predator here as in the southern North Sea. © 2016 The Fisheries Society of the British Isles.

  16. Two Competing Normative Trajectories in the Context of the First Baltic Gay Pride Parade in Lithuania

    Directory of Open Access Journals (Sweden)

    Mažylis Liudas

    2014-12-01

    Full Text Available For a long time post-Soviet space has been perceived as homophobic and intolerant of LGBT persons. The three Baltic States - Lithuania, Latvia and Estonia - as former Soviet republics and current members of the European Union, represent the space where a strong homophobic post-Soviet atmosphere competes with pro-LGBT Western influence. This article examines how the first LGBT Pride Parade (which occurred in Vilnius in 2010 is reflected in Lithuanian media portals. The article also presents the broader context of LGBT issues by reviewing legal changes and Lithuanian political parties’ programs. Our analysis of the media and other sources is based on three arguments: 1 that the LGBT pride parade in Vilnius became the most important event for reflecting LGBT issues in the media and society; 2 it might have not been possible without support and influence from external institutions; and 3 the LGBT parade revealed the division of two competing normative trajectories in Lithuania. The reconstructed trajectories in the article are based on the theoretical framework of new institutionalism, media analysis, interviews and focus groups. Construction of the LGBT campaign and counter-campaign seem delimited rather than approaching them as value normative consensus. However, the way in which LGBT persons are reflected within the Lithuanian media is remarkably different in comparison with the early post-Soviet period. The Baltic gay pride parade “for equality” and external (Western support for it were highly visible in the media, influenced a significant debate on the topic not otherwise experienced in Lithuania, and (reintroduced a question about the perception of ‘normality’ within society. These debates also raise the question of how norms and institutions change and adapt within society.

  17. 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.

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

    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.

    2004-09-01

    Full Text Available A Berner cascade impactor was used for the separation of solid urban aerosols in two localities of the Baltic coastal macro-region - Słupsk and Hel - in different seasons and weathers. Ten ranges of aerodynamic diameters between 0.009 and 8.11 µm were used. The elementary composition for each diameter was obtained in a complex procedure consisting of laser ablation of deposits, then their successive ionization in an inductively coupled plasma generator, and finally, mass selection in a quadrupole spectrometer. Despite its complexity, the chemical element analysis method proved to be versatile, allowing the identification air pollution from natural and industrial sources, and road traffic.

    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.

    2008-11-06

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

    Full Text Available Transnational (involving countries and cross-border (involving adjacent regions of different countries cooperation and integration are rapidly developing in the Baltic Sea region. Russia lags behind the Nordic countries and Germany as far as innovative development is concerned; yet our national pace here is comparable to that of Poland and the three Baltic States. At the same time, the features of innovative cooperation vary a great deal depending on the group of countries involved in cooperation processes. Independent of its type, however, international cooperation is beneficial for all parties concerned and should therefore be more actively encouraged. Northwestern Federal District traditionally plays a special role in the development of EU-Russia cooperation, since a number of its regions border on the EU countries. The district participates in the development of network innovative structures within the Baltic Sea region. It takes an active part in cross-border cooperation — activities that involve the formation of transborder innovative clusters. There are high expectations associated with the formation of such territorially localised innovative networks, as the Helsinki — Saint Petersburg — Tallinn and Tricity (Gdansk, Gdynia, Sopot — Kaliningrad — Klaipeda transborder innovative clusters. The city of Saint Petersburg and the adjacent Leningrad region, as well as the Kaliningrad region can become innovative development corridors between Russia and the EU and, eventually, develop into the ‘economic growth poles’ of the Russian Federation.

  10. The prospects of nuclear power development in the eastern part of the Baltic Sea region as a factor of the formation of international relations system in the region

    Directory of Open Access Journals (Sweden)

    Mezhevich Nikolai

    2013-05-01

    Full Text Available The current development of economic diplomacy in the world is determined by a combination of globalization and regionalization. In addition, it has an economic dimension. At the same time, the Baltic Sea region demonstrates large-scale politicisation of economic cooperation. The development of nuclear power in the eastern part of the Baltic Sea is indicative of the effectiveness of political and economic cooperation in the region. The author believes that Russia and the three Baltic States of Estonia, Latvia and Lithuania have the economic and technological opportunities for building up cooperation in the field of energy. This points to a question whether the traditional patterns of relations that developed among these countries in the past can be changed. A more pronounced international division of labour accompanied by the historically developed specialization of Russia makes nuclear power an important factor in Russia’s economic diplomacy. The promotion of Russian energy projects in the region contributes to the development of a system of mutually beneficial ties. The increasing energy deficiency in the region can serve an economic prerequisite to this process.

    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

  16. Toxic substances and reproductive disorders in Baltic fish and crustaceans.

    Science.gov (United States)

    Breitholtz, M; Hill, C; Bengtsson, B E

    2001-08-01

    In the Baltic Sea ecosystem reproductive disorders have occurred in top consumers such as seals and some fish-eating birds, due to biomagnification of toxic substances, e.g. DDT and PCBs. Reproductive disturbances have also affected fish during the last 25 years. However, there is no strong evidence that toxic substances have caused these problems. Rather, the disorders seem to result from a combination of two or more biotic or abiotic factors. The M74 syndrome, which kills fry of salmon and sea trout, is characterized by a deficiency of thiamine (vitamin B1). Several factors may contribute to the thiamine deficiency, including the diet of salmon in the sea and halogenated organic compounds. Cod do not develop M74, and poor cod recruitment is mainly due to poor oxygen conditions in the spawning areas in combination with overfishing. Toxic compounds in pulp-mill effluents retard gonadal development in perch, but the mechanisms and the active substances have not been identified. Recruitment problems in perch in the coastal waters outside some pulp mills may also be explained by a lack of food items for juvenile fish, rather than reproductive failure. There are very limited data on reproductive disorders in crustaceans from the Baltic Sea. Most data come from studies of the benthic amphipod Monoporeia affinis, which has been used in monitoring programs. Several signs of reproductive disorder have been reported in this amphipod, e.g. malformation and death of embryos, and asynchronous maturation of males and females.

    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.

    2015-09-01

    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.

    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.

    The contamination with microplastic particles and fibres was evaluated on beaches along the German Baltic coast. Sediments were sampled near the Warnow and Oder/Peene estuaries, on Rügen island and along the Rostock coast to derive possible entry pathways. Seasonal variations were monitored along the Rostock coast from March to July 2014. After density separation in saline solution, floating particles were found to be dominated by sand grains. Water surface tension is shown to be sufficient to explain floatation of grains with sizes less than 1.5mm. Selecting intensely coloured particles and fibres, we find lower limits of the microplastic concentrations of 0-7 particles/kg and 2-11 fibres/kg dry sediment. The largest microplastic contaminations are measured at the Peene outlet into the Baltic Sea and in the North Sea Jade Bay. City discharges, industrial production sites, fishing activity and tourism are the most likely sources for the highest microplastic concentrations. Copyright © 2015 Elsevier Ltd.

    The Baltic Sea is heavily polluted yet supports major commercial fisheries for cod (Gadus morhua), herring (Clupea harengus), and sprat (Sprattus sprattus). Emissions of persistent organic pollutants, such as polychlorinated biphenyls (PCBs) and DDT, were high during the 1960s and 1970s, and concentrations in fish and other fauna are still significant. Several models of the fluxes of these pollutants among the water, sediment, and atmosphere have been developed, but these generally omit the roles of fish and fisheries. We show that the standing stock of the most abundant fish species in the Baltic Sea was a sink for 260 kg of PCBs in the late 1980s to early 1990s and that the fishery removed as much or more PCB (31 kg yr(-1))than other budget components (e.g., degradation in the water column). Accounting for fish and fisheries could increase our understanding of the fluxes of pollutants, and banning the discard of highly contaminated organs such as cod liver could be part of the pollution management.

    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.

    State-of-the art dispersion models were applied to simulate {sup 137}Cs dispersion from Chernobyl nuclear power plant disaster fallout in the Baltic Sea and from Fukushima Daiichi nuclear plant releases in the Pacific Ocean after the 2011 tsunami. Models were of different nature, from box to full three-dimensional models, and included water/sediment interactions. Agreement between models was very good in the Baltic. In the case of Fukushima, results from models could be considered to be in acceptable agreement only after a model harmonization process consisting of using exactly the same forcing (water circulation and parameters) in all models. It was found that the dynamics of the considered system (magnitude and variability of currents) was essential in obtaining a good agreement between models. The difficulties in developing operative models for decision-making support in these dynamic environments were highlighted. Three stages which should be considered after an emergency, each of them requiring specific modelling approaches, have been defined. They are the emergency, the post-emergency and the long-term phases. - Highlights: • Models applied to simulate {sup 137}Cs marine dispersion after nuclear accidents. • Not good agreement initially found in highly dynamic environments. • Difficulties in developing models for decision making after emergencies highlighted.

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.

    The most versatile and promising technology for solving problems of monitoring and analysis of the natural environment is a four-dimensional variational data assimilation of observation data. In such problems not only the development and justification of algorithms for numerical solution of variational data assimilation problems but the properties of the optimal solution play an important role. In this work the variational data assimilation problems in the Baltic Sea water area were formulated and studied. Numerical experiments on restoring the ocean heat flux and obtaining solution of the system (temperature, salinity, velocity, and sea surface height) in the Baltic Sea primitive equation hydrodynamics model with assimilation procedure were carried out. In the calculations we used daily sea surface temperature observation from Danish meteorological Institute, prepared on the basis of measurements of the radiometer (AVHRR, AATSR and AMSRE) and spectroradiometer (SEVIRI and MODIS). The spatial resolution of the model grid with respect to the horizontal variables amounted to 0.0625x0.03125 degree. The results of the numerical experiments are presented. This study was supported by the Russian Foundation for Basic Research (project 13-01-00753, project 14-01-31195) and project 14-11-00609 by the Russian Science Foundation. References: 1 E.I.

    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.

    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.

A policy process is one characterized by delays. It may take years from problem identification to a decision to taking action and several years further for actual implementation. Ecosystem responses to measures illustrate that feedback can keep the ecosystem in a certain state and cause a delay in ecosystem response. These delays can operate on decadal scales. Our aim in this paper is to analyze these systemic delays and especially to discuss how the critical delays can be better addressed in marine protection policies by strengthening the adaptive capacity of marine protection. We conclude that the development of monitoring systems and reflexive, participatory analysis of dynamics involved in the implementation are keys to improve understanding of the systemic delays. The improved understanding is necessary for the adaptive management of a persistent environmental problem. In addition to the state of the environment, the monitoring and analysis should be targeted also at the implementation of policies to ensure that the societies are investing in the right measures.

    Instrumental observations in the Baltic Sea are reaching back into the 19th century, but a comprehensive ecosystem monitoring by means of coastal stations, research vessels, moorings, permanent stations, and satellites was developed stepwise after WWII and significantly intensified after founding of the HELCOM (Helsinki Commission) in 1975 for protecting the Baltic marine environment against anthropogenic influences. Such influences are well recorded in surface sediments of the different Baltic Sea sub-basins, where i.a. heavy metal and organic pollutants accumulated in the course of the last century with characteristic rates. However, despite of the vast amount of instrumental data, calibration of paleoenvironmental proxies is often complicated due to weakly constraint chronologies of these young sediments. In many cases sedimentation is not continuous and sediments are subject to erosion, re-suspension, lateral transport, and focusing due to intense wind driven waves and current activity. Therefore, a direct link of sedimentary proxies with instrumental water column observations is not always straightforward and generally not well established. Recently developed event stratigraphic and radionuclide based chronologies in some restricted Baltic Sea areas like the central Baltic deeps form now a solid base for the in depth proxy development and validation with instrumental time series. Promising results come from e.g. the solid-phase Mn and trace element signatures and organic biomarkers in recent/sub-recent sediments from the central Baltic Sea enhancing the potential of reconstructing the Littorina-Stage environmental development.

  10. A new soldier beetle from Eocene Baltic amber

    2017-11-01

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

    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.

    2014-04-01

    Full Text Available In a climate change context, changes in extreme sea-levels rather than changes in the mean are of particular interest from the coastal protection point of view. In this work, extreme sea-levels in the Baltic Sea are investigated based on daily tide gauge records for the period 1916–2005 using the annual block maxima approach. Extreme events are analysed based on the generalised extreme value distribution considering both stationary and time-varying models. The likelihood ratio test is applied to select between stationary and non-stationary models for the maxima and return values are estimated from the final model. As an independent and complementary approach, quantile regression is applied for comparison with the results from the extreme value approach. The rates of change in the uppermost quantiles are in general consistent and most pronounced for the northernmost stations.

    Single and multispecies models are used to examine the effect of species interaction on biological reference points for cod, herring, and sprat in the Baltic. The results demonstrate that reference points are different in single and multispecies contexts. Reference points for fishing mortality...... based on single-species yield and SSB calculations are difficult to use when natural mortality depends on the absolute abundance of the predators and their alternative prey. Reference points based on maximizing total yield from the system may lead to impractical results when species interact...... reference points.

In the single species situation the combinations of cod and pelagic fishing effort for which the equilibrium spawning- stock biomass of the three species is above the biomass reference points forms a rectangular area...

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

    Zobkov, M; Esiukova, E

    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.

    2012-07-01

    This study is made as a part of the Chembaltic (Risks of Maritime Transportation of Chemicals in Baltic Sea) project which gathers information on the chemicals transported in the Baltic Sea. The purpose of this study is to provide an overview of handling volumes of liquid bulk chemicals (including liquefied gases) in the Baltic Sea ports and to find out what the most transported liquid bulk chemicals in the Baltic Sea are. Oil and oil products are also viewed in this study but only in a general level. Oils and oil products may also include chemical-related substances (e.g. certain bio-fuels which belong to MARPOL annex II category) in some cargo statistics. Chemicals in packaged form are excluded from the study. Most of the facts about the transport volumes of chemicals presented in this study are based on secondary written sources of Scandinavian, Russian, Baltic and international origin. Furthermore, statistical sources, academic journals, periodicals, newspapers and in later years also different homepages on the Internet have been used as sources of information. Chemical handling volumes in Finnish ports were examined in more detail by using a nationwide vessel traffic system called PortNet. Many previous studies have shown that the Baltic Sea ports are annually handling more than 11 million tonnes of liquid chemicals transported in bulk. Based on this study, it appears that the number may be even higher. The liquid bulk chemicals account for approximately 4 % of the total amount of liquid bulk cargoes handled in the Baltic Sea ports. Most of the liquid bulk chemicals are handled in Finnish and Swedish ports and their proportion of all liquid chemicals handled in the Baltic Sea is altogether over 50 %. The most handled chemicals in the Baltic Sea ports are methanol, sodium hydroxide solution, ammonia, sulphuric and phosphoric acid, pentanes, aromatic free solvents, xylenes, methyl tert-butyl ether (MTBE) and ethanol and ethanol solutions. All of these chemicals

    In 2009-2012 at University of Latvia and Latvia University of Agriculture project "Establishment of interdisciplinary scientist group and modelling system for groundwater research" is implemented financed by the European Social Fund. The aim of the project is to develop groundwater research in Latvia by establishing interdisciplinary research group and modelling system covering groundwater flow in the Baltic Sedimentary Basin. Researchers from fields like geology, chemistry, mathematical modelling, physics and environmental engineering are involved in the project. The modelling system is used as a platform for addressing scientific problems such as: (1) large-scale groundwater flow in Baltic Sedimentary Basin and impact of human activities on it; (2) the evolution of groundwater flow since the last glaciation and subglacial groundwater recharge; (3) the effects of climate changes on shallow groundwater and interaction of hydrographical network and groundwater; (4) new programming approaches for groundwater modelling. Within the frame of the project most accessible geological information such as description of geological wells, geological maps and results of seismic profiling in Latvia as well as Estonia and Lithuania are collected and integrated into modelling system. For example data form more then 40 thousands wells are directly used to automatically generate the geological structure of the model. Additionally a groundwater sampling campaign is undertaken. Contents of CFC, stabile isotopes of O and H and radiocarbon are the most significant parameters of groundwater that are established in unprecedented scale for Latvia. The most important modelling results will be published in web as a data set. Project number: 2009/0212/1DP/1.1.1.2.0/09/APIA/VIAA/060. Project web-site: www.puma.lu.lv

    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.

  2. Towards uncertainty estimation for operational forecast products - a multi-model-ensemble approach for the North Sea and the Baltic Sea

    2014-05-01

    Several independent operational ocean models provide forecasts of the ocean state (e.g. sea level, temperature, salinity and ice cover) in the North Sea and the Baltic Sea on a daily basis. These forecasts are the primary source of information for a variety of information and emergency response systems used e.g. to issue sea level warnings or carry out oil drift forecast. The forecasts are of course highly valuable as such, but often suffer from a lack of information on their uncertainty. With the aim of augmenting the existing operational ocean forecasts in the North Sea and the Baltic Sea by a measure of uncertainty a multi-model-ensemble (MME) system for sea surface temperature (SST), sea surface salinity (SSS) and water transports has been set up in the framework of the MyOcean-2 project. Members of MyOcean-2, the NOOS² and HIROMB/BOOS³ communities provide 48h-forecasts serving as inputs. Different variables are processed separately due to their different physical characteristics. Based on the so far collected daily MME products of SST and SSS, a statistical method, Empirical Orthogonal Function (EOF) analysis is applied to assess their spatial and temporal variability. For sea surface currents, progressive vector diagrams at specific points are consulted to estimate the performance of the circulation models especially in hydrodynamic important areas, e.g. inflow/outflow of the Baltic Sea, Norwegian trench and English Channel. For further versions of the MME system, it is planned to extend the MME to other variables like e.g. sea level, ocean currents or ice cover based on the needs of the model providers and their customers. It is also planned to include in-situ data to augment the uncertainty information and for validation purposes. Additionally, weighting methods will be implemented into the MME system to develop more complex uncertainty measures. The methodology used to create the MME will be outlined and different ensemble products will be presented. In

    2009-01-01

    The removal and safe disposal of RTGs and their replacement with solar panel technology in the Baltic Sea is a priority area under the Norwegian Nuclear Action Plan. 26 of the 87 RTGs around the Baltic Sea have been removed as of 7th October 2009. The removal of RTGs around the Baltic Sea was initiated in 2009 as part of the Norwegian-Russian cooperation with funding from Norway, which requires that risk and environmental impact assessments are carried out during the planning phase. Finland and France will also be contributing to the work of removal and safe disposal of the RTGs around the Baltic Sea. (Author)

  4. 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.

  5. Use of regional climate models data for groundwater recharge modelling in Baltic artesian basin

    Baltic artesian basin (BAB) covers about 480000 square kilometres. BAB includes territory of Latvia, Lithuania, Estonia, parts of Poland, Russia, Belarus and Baltic Sea. The closed hydrogeological mathematical model for the BAB is developed in University of Latvia and reference calculations made in steady state mode. No-flow boundary condition is applied on the bottom and side boundaries of BAB. Hydraulic head is fixed on the seabed and largest lakes, and along the main river lines. Main water supply wells also are presented in the model as a pointwise water extraction. Precipitation is the main source of the groundwater recharge in the BAB region. Infiltration parameterization is responsible for this water source in BAB model. During the early stage of calibration of BAB hydrogeological model an automatic calibration for the hydraulic conductivities of permeable layers and single infiltration rate was attempted. Performing BAB model calibration it was noted that the differences of calculated and observed hydraulic heads (used for calculating the calibration penalty function) can be reduced by introducing a spatially distributed infiltration model. The aim of the present study is improving of the infiltration model, as well as preserving a short computation time (several minutes) for the piezometric head. Direct solution of improvement of the infiltration would be a usage of the advanced hydrological models. However, an accurate hydrological model requires a lot of computational power. It should couple meteorological and hydrological parameters and requires additional calibration. The regional climate model (KNMI-RACMO2 25 km resolution) results from ENSEMBLES project are used for the spatially distributed infiltration field calculation. The infiltration field is constructed as weighted difference of 30 year averaged precipitation and evaporation fields. The weight value is calibrated and a considerable decrease of the value of penalty function of the groundwater

    Saks, T.; Sennikovs, J.; Timuhins, A.; Kalvāns, A.

    2012-04-01

    In last decades it has been discussed that most large ice sheets tend to reside on warm beds even in harsh clima tic conditions and subglacial melting occurs due to geothermal heat flow and deformation heat of the ice flow. However the subglacial groundwater recharge and flow conditions have been addressed in only few studies. The aim of this study is to establish the groundwater flow pattern in the Baltic Basin below the Scandinavian ice sheet during the Late Weichselian glaciation. The calculation results are compared to the known distribution of the groundwater body of the glacial origin found in Cambrian - Vendian (Cm-V) aquifer in the Northern Estonia which is believed to have originated as a result of subglacial meltwater infiltration during the reoccurring glaciations. Steady state regional groundwater flow model of the Baltic Basin was used to simulate the groundwater flow beneath the ice sheet with its geometry adjusted to reflect the subglacial topography. Ice thickness modelling data (Argus&Peltier, 2010) was used for the setup of the boundary conditions: the meltwater pressure at the ice bed was assumed equal to the overlying ice mass. The modelling results suggest two main recharge areas of the Cm-V aquifer system, and reversed groundwater flow that persisted for at least 14 thousand years. Model results show that the groundwater flow velocities in the Cm-V aquifer in the recharge area in N-Estonia beneath the ice sheet exceeded the present velocities by a factor of 10 on average. The calculated meltwater volume recharged into the Cm-V aquifer system during the Late Weichselian corresponds roughly to the estimated, however, considering the fact, that the study area has been glaciated at least 4 times this is an overestimation. The modeling results attest the hypothesis of light dO18 groundwater glacial origin in the Cm-V aquifer system, however the volumes, timing and processes involved in the meltwater intrusion are yet to be explored.

    In a recent ‘As We See It’ article, Cardinale & Svedäng (2011; Mar Ecol Prog Ser 425:297–301) used the example of the Eastern Baltic (EB) cod stock to argue that the concept of ecosystem regime shifts, especially the potential existence of alternative stable states (or dynamic regimes), blurs...... the fact that human exploitation (i.e. fishing) is the strongest impact on marine ecosystems. They further concluded that single-species approaches to resource management are functioning and that ecosystem-based approaches are not necessary. We (1) argue that the recent increase in the EB cod stock...... is inherently uncertain, (2) discuss the critique of the regime shift concept, and (3) describe why the EB cod stock dynamics demonstrates the need for an ecosystem approach to fisheries management....

    Full text: Anthropogenic input of 129 I has provided a number of applications in the marine and terrestrial environments. The discharged quantities into the atmosphere and the oceans have not been of particular health concern for regions at considerable distance from the discharge sources, as the Baltic Sea. Marine currents and wind patterns affect the migration and distribution of 129 I to and in the Baltic Sea, but there are no sufficient measured data to predict present day and future distribution of the isotope. Modeling may, in some cases, become an excellent alternative of prediction and later comparison with measured data, when they become available, can improve and correct the model results. Here we present a mass-balance model (SPM) originally established for phosphorus by Haekanson (2007), but slightly modified in this work to accommodate to calculation of 129 I concentration the Baltic Sea from different depths. The model is based on conventional equations and the processes governing elemental dynamic in the Baltic Sea such as mixing and diffusion. The calculated values were assessed with the average empirical data and reasonably matched in most areas of Baltic Sea. Moreover, 129 I fluxes corresponding to different parts of Baltic Sea are estimated which are, to our best knowledge, never done before but are the indispensable task for further research. Due to the semi-close characteristics of Baltic Sea, 129 I has a relatively long residence time and model prediction failed to run as they largely rely on meteorological data (temperature, precipitation and winds) which are difficult to prognoses and thus doubtful on a long time span. Despite this difficulty, the model presented here seems successful for prediction on a long timescale as all derived variables are accessed from GIS maps. (author)

  9. Juvenile flatfish in the northern Baltic Sea - long-term decline and potential links to habitat characteristics

    2016-01-01

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

    Geological Storage of CO2 in the Southern Baltic Sea Region The BASTOR project identifies and characterises the potential CO2 storage sites in the southern Baltic Sea. A regional theoretical storage capacity of 16Gt of CO2 in the Middle Cambrian sandstone beneath 900 metres of cap rock was estimated. 1.9Gt of this storage potential is estimated in the Dalders Monocline with some 743Mt CO2 in individual hydrocarbon and saline aquifer structures located mainly offshore Latvia and 128Mt in the Dalders Structure. Although the study has established a relatively large theoretical storage capacity, there is no effective capacity proven within these totals. Dynamic modelling undertaken in the Southern Swedish sector suggests that the relatively poor permeability and porosity characteristics would limit the injection rate to 0.5Mt per well per annum and restrict the reservoir pressure increase to 50% above the hydrostatic pressure for an injection period of 50 years. The dynamic modelling for this area suggests that an injection strategy for this sector would be limited to 5 injection wells giving a total injection capacity of 2.5 Mt per annum. Based on these results, the potential of the Southern Swedish offshore sector to sustain injection rates of CO2 required for regional industrial capture, even when using horizontal wells, brine extraction and hydraulic fracturing, would appear to be very low. Areas to the north east of the Monocline, such as offshore Latvia have been identified as having better reservoir quality despite limited data being available. These areas could sustain higher rates of injection and prove suitable areas for commercial storage. Furthermore, the regional storage capacity assessment demonstrated that there are sweet spots in the Cambrian reservoir such as onshore Latvia, where there is commercial gas storage, and both onshore and offshore Kaliningrad, where there is ongoing hydrocarbon production. The potential for seal failure was investigated as

    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

    The biogeochemical cycling of iron is a key early diagenetic process. However, limited information exists about the diversity and metabolic pathways of microorganisms linked to iron cycling in marine sediments. The goal of this study was to determine the bacterial community diversity in sediments showing ongoing dissimilatory iron reduction using 454-pyrosequencing as a first step in characterizing microorganisms potentially involved in iron reduction. For this purpose, two 35 cm cores were sampled from ferruginous sediments in the Skagerrak (SK) and the Bothnian Bay (BB) from the North-Sea Baltic Sea and the northern Baltic Sea respectively. Pore water profiles showed Fe2+ and Mn2+ levels of ~140-150 µM throughout the core below a 6 cm thick oxidized surface layer in SK sediments and ~300 µM below a 2 cm thick surface layer in BB sediments. Dissolved sulphide levels were below detection in both sediments. No significant depletion of SO42- occurred at both sites, further supported by stable S and O isotope analyses of dissolved sulfate at SK site. Only very minor net sulfate reduction is suggested here from the trend in sulphur isotope signatures, in agreement with previously reported gross microbial sulphate rate measurements (Canfield et al., 1993;GCA). Based on these biogeochemical constraints, Fe reduction in the studied sediments is therefore dominated by microbial dissimilatory iron reduction, while cryptic Fe-S-cycling can be largely excluded. 16S rRNA gene sequences indicate Proteobacteria as the dominating microbial group in these sediments. Potential iron and manganese reducing bacteria included Geobacteraceae, Pelobacteraceae, Shewanellaceae, and Oceanospirillales. Additionally, Actinobacteria and Bacteroidetes were present. Also, Fe-oxidizers were present and their occurrence correlated in depth with a Fe-oxide-rich layer, most likely a former buried Fe-oxidation front. Gene sequences point to the presence of Mariprofundus in SK sediments and

    Connectivity plays an important role in shaping the genetic structure and in evolution of local adaptation. In the marine environment barriers to gene flow are in most cases caused by gradients in environmental factors, ocean circulation and/or larval behavior. Despite the long pelagic larval stages, with high potential for dispersal many marine organisms have been shown to have a fine scale genetic structuring. In this study, by using a combination of high-resolution genetic markers, species hybridization data and biophysical modeling we can present a comprehensive picture of the evolutionary landscape for a keystone species in the Baltic Sea, the blue mussel. We identified distinct genetic differentiation between the West Coast, Baltic Proper and Bothnian Sea regions, with lower gene diversity in the Bothnian Sea. Oceanographic connectivity together with salinity and to some extent species identity provides explanations for the genetic differentiation between the West Coast and the Baltic Sea (Baltic Proper and Bothnian Sea). The genetic differentiation between the Baltic Proper and Bothnian Sea cannot be directly explained by oceanographic connectivity, species identity or salinity, while the lower connectivity to the Bothnian Sea may explain the lower gene diversity.

    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

    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.)

    In the Helsinki Commission Red List project 2009-2012, taxonomic and distributional data of benthic (macro) invertebrates were compiled by the present authors in a comprehensive checklist of the Baltic Sea fauna. Based on the most recent and comprehensive data, this paper presents the diversity patterns observed among benthic invertebrates in the Baltic Sea. As expected, the total number of species per sub-region generally declined along the salinity gradient from the Danish Straits to the northern Baltic Sea. This relationship is well known from the Baltic Sea and has resulted in a general assumption of an exponentially positive relationship between species richness and salinity for marine species, and a negative relationship for freshwater species. In 1934, Remane produced a diagram to describe the hypothetical distribution of benthic invertebrate diversity along a marine-freshwater salinity gradient. Our results clearly indicated the validity of this theory for the macrozoobenthic diversity pattern within the Baltic Sea. Categorisation of sub-regions according to species composition showed both separation and grouping of some sub-regions and a strong alignment of similarity patterns of zoobenthic species composition along the salinity gradient.

    Full Text Available A new fossil fly species, Acartophthalmites willii sp. n. (Diptera: Acalyptratae: Opomyzoidea from Baltic amber (Eocene, 56−33.9 Ma, is described based on a male originally assigned by Hennig (1969 to A. tertiaria Hennig, 1965, who erroneously also referred to it in the same work as “A. electrica Hennig” (unavailable name. The new species, representing the third named species of the extinct genus with unclear familial relationships Acartophthalmites Hennig, 1965, is herein described and illustrated in detail, and its systematic implications and relationships are discussed. From the morphological standpoint, the new species represents an intermediate form between the two formerly described species within the genus, therefore expanding the character combination diversity in this lineage of acalyptrate flies. The genus Acartophthalmites is considered to be most closely related to Clusiidae and, therefore, it is herein tentatively classified within the superfamily Opomyzoidea. The current work takes part of an effort to review the Acartophthalmites diversity in order to gain knowledge on the morphological data from the specimens described within the genus and ultimately enable a reliable analysis of its phylogenetic relationships with other acalyptrates.

    This study was undertaken to determine sorption coefficients of eight herbicides (alachlor, amitrole, atrazine, simazine, dicamba, imazamox, imazethapyr, and pendimethalin) to seven agricultural soils from sites throughout Lithuania. The measured sorption coefficients were used to predict the susceptibility of these herbicides to leach to groundwater. Soil-water partitioning coefficients were measured in batch equilibrium studies using radiolabeled herbicides. In most soils, sorption followed the general trend pendimethalin > alachlor > atrazine approximately amitrole approximately simazine > imazethapyr > imazamox > dicamba, consistent with the trends in hydrophobicity (log K(ow)) except in the case of amitrole. For several herbicides, sorption coefficients and calculated retardation factors were lowest (predicted to be most susceptible to leaching) in a soil of intermediate organic carbon content and sand content. Calculated herbicide retardation factors were high for soils with high organic carbon contents. Estimated leaching times under saturated conditions, assuming no herbicide degradation and no preferential water flow, were more strongly affected by soil textural effects on predicted water flow than by herbicide sorption effects. All herbicides were predicted to be slowest to leach in soils with high clay and low sand contents, and fastest to leach in soils with high sand content and low organic matter content. Herbicide management is important to the continued increase in agricultural production and profitability in the Baltic region, and these results will be useful in identifying critical areas requiring improved management practices to reduce water contamination by pesticides.

    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.

    Wilewska-Bien, Magda; Granhag, Lena; Andersson, Karin

    2016-04-15

    The combination of the sensitive characteristics of the Baltic Sea and the intense maritime traffic makes the marine environment vulnerable to anthropogenic influences. The theoretical scenario calculated in this study shows that the annually generated food waste onboard ships in traffic in the Baltic Sea contains about 182tonnes of nitrogen and 34tonnes of phosphorus. Today, all food waste generated onboard can be legally discharged into the marine environment at a distance of 12NM from the nearest land. The annual load of nitrogen contained in the food waste corresponds to 52% of load of nitrogen from the ship-generated sewage. Future regulations for sewage discharge in the Baltic Sea will require significant reduction of total nitrogen and phosphorus released. The contribution of nutrients from food waste compared to sewage will therefore be relatively larger in the future, if food waste still can be legally discharged. Copyright © 2015 Elsevier Ltd.

    2010-01-01

    Modern embryology is grounded on the research of Pander (theory of germ-layers), von Baer (human egg) and Rathke (branchial arches in mammals). All these scientists lived and worked in the Baltic region. They held professorships at the universities of Koenigsberg and Dorpat and at the Imperial Academy of St. Petersburg, thus moving between the Kingdom of Prussia and the Russian Czardom. Since the Baltic countries are not commonly considered to be predestined as a birthplace of embryology, special attention is turned to the coincidences that, there of all places, made those people focus on that special field of research. Considering the peripheral position of the Baltic, the paper examines personal relations, national identities, cultural exchange, and local working conditions, including room for development as well as formidable obstacles.

    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.

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

    The Baltic Sea region is one of the most contaminated areas with persistent organic pollutants (POPs) including polychlorinated dibenzo-p-dioxins and dibenzofurans (dioxins). The high load of dioxins in Baltic fish has lead to restrictions of the use of contaminated fish for human consumption. Uncertainties about sources, geographical distribution of these contaminants, the pathways of bioaccumulation and possible ecotoxicological and human health effects are of concern. POPs may enter the Baltic Sea from atmospheric deposition, riverine input and point sources along the coast. The ultimate sink for the majority of the compounds is the open sea and coastal sediments, although some fraction enters the food chain. Analysis of sediment has been widely used to study regional and temporal trends of dioxin pollution in freshwater and oceans and the Baltic Sea has been one of the most studied sea areas for dioxin-like compounds as well. Only a fraction (unknown) of the analytical results have been published in scientific papers, however. Here we present regional distribution of certain congeners of dioxins in surface sediments and in six sediment cores from the Baltic Sea. New data is compared with data on earlier Finnish sediment surveys. Some data from published papers and unpublished data from the Kattegat Sound is also given for reference. The purpose of this paper is to: 1. get an ''draft'' picture of regional distribution (possible hot spots, major regional differences) along the Finnish-Swedish-Danish-German coastal and open sea sites in the Baltic 2. study differences in congener distributions (source identification) 3. study temporal changes in sediment profiles 4. identify major areas with gap of data 5. call for more data (both published and grey literature as well as new sediment surveys)

    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.

    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.)

  17. Model-supported estimation of mortality rates in Baltic cod (Gadus morhua callarias L. larvae: the varying impact of 'critical periods'

    Full Text Available Abstract Background Changes in the survival-rate during the larval phase may strongly influence the recruitment level in marine fish species. During the larval phase different 'critical periods' are discussed, e.g. the hatching period and the first-feeding period. No such information was available for the Baltic cod stock, a commercially important stock showing reproduction failure during the last years. We calculated field-based mortality rates for larval Baltic cod during these phases using basin-wide abundance estimates from two consecutive surveys. Survey information was corrected by three dimensional hydrodynamic model runs. Results The corrections applied for transport were of variable impact, depending on the prevailing circulation patterns. Especially at high wind forcing scenarios, abundance estimates have the potential to be biased without accounting for transport processes. In May 1988 mortality between hatch and first feeding amounted to approximately 20% per day. Mortality rates during the onset of feeding were considerably lower with only 7% per day. In August 1991 the situation was vice versa: Extremely low mortality rates of 0.08% per day were calculated between hatch and first feeding, while the period between the onset of feeding to the state of an established feeder was more critical with mortality rates of 22% per day. Conclusions Mortality rates during the different proposed 'critical periods' were found to be highly variable. Survival rates of Baltic cod are not only influenced by a single 'critical period', but can be limited at different points during the larval phase, depending on several biotic and abiotic factors.

    2016-01-01

    Military sonars are known to have caused cetaceans to strand. Navies in shallow seas use different frequencies and sonar pulses, commonly frequencies between 25 and 100 kHz, compared with most studied NATO sonar systems that have been evaluated for their environmental impact. These frequencies match the frequencies of best hearing in the harbor porpoises and seals resident in the Baltic Sea. This study uses published temporary and permanent threshold shifts, measured behavioral response thresholds, technical specifications of a sonar system, and environmental parameters affecting sound propagation common for the Baltic Sea to estimate the impact zones for harbor porpoises and seals.

    1983-01-01

    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)

    Climate model outputs include numerous variables of possible interest for modelling climate change impacts on the hydrodynamics and water quality of coastal-marine systems. In addition, various climate models perform differently well and their results exhibit various degrees of uncertainty. To constructively focus and increase robustness and reliability in projection simulations and assessments of future climate-change effects on coastal-marine environments, there is a need to investigate if any climate change variables may be particularly important to consider. As a way forward to determine this for the Baltic Sea, this study identifies and considers three representative years with different hydro-climatic driver-effect settings. These include, e.g., different conditions for heat flux, wind, water levels, and freshwater and saltwater influxes to the Baltic Sea. The three representative years and their different driver-effect characteristics are further used for forcing and validation of three-dimensional hydrodynamic Baltic Sea modeling, using the FVCOM open-source code model. The simulation results show that the heat flux input is the predominant driver of water temperature conditions in the Baltic Sea. Furthermore, they show that the river runoff is significantly correlated with the saltwater influx at the open Baltic Sea boundary, with these two variables working together to predominantly determine the salinity conditions in the sea. Moreover, flow structure is studied in terms of flow directions and rates among the main marine basins of the Baltic Sea. The results show that the directions of flows are quite stable, but the flow magnitudes fluctuate considerably and are mainly influenced by the prevailing wind conditions. For the Baltic Sea, this study has thus identified as predominant driver-effect combinations: heat flux-sea temperature, runoff (and correlated open-boundary influx)-sea salinity, and wind-sea flow structure. These results facilitate and will

  10. Seabird guano fertilizes Baltic Sea littoral food webs.

    Directory of Open Access Journals (Sweden)

    Karine Gagnon

    Full Text Available Nutrient enrichment in coastal marine systems can have profound impacts on trophic networks. In the Baltic Sea, the population of Great Cormorant (Phalacrocorax carbo sinensis has increased nearly exponentially since the mid-1990 s, and colonies of these seabirds can be important sources of nitrogen enrichment for nearby benthic communities due to guano runoff. In this study we used stable isotope analyses and diet mixing models to determine the extent of nitrogen enrichment from cormorant colonies, as well as to examine any possible changes in herbivore diet preferences due to enrichment. We found significantly higher levels of δ(15N in samples from colony islands than control islands for producers (the dominant macroalga Fucus vesiculosus, filamentous algae, and periphyton and herbivores, as well as a positive correlation between enrichment and nest density in colony sites. We also found that enrichment increased over the breeding season of the cormorants, with higher enrichment in late summer than early summer. While the amount of total nitrogen did not differ between colony and control sites, the amount of guano-based nitrogen in algae was >50% in most sites, indicating high nitrogen enrichment from colonies. Herbivores (the isopod Idotea balthica and the gastropod Theodoxus fluviatilis preferred feeding upon the dominant macroalga Fucus vesiculosus rather than on filamentous algae or periphyton in both control and colony, and there was a significant increase in periphyton consumption near colony sites. Overall, guano from cormorant colonies seems to have effects on both producers and herbivores, as well as the potential to modify algae-herbivore interactions.

  11. 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.

    It is known that the structure of benthic macrophyte and invertebrate habitats indicate the quality of coastal water. Thus, a large-scale analysis of the spatial patterns of coastal marine habitats makes it possible to adequately estimate the status of valuable coastal marine habitats, provide better evidence for environmental changes, and describe the processes behind the changes. Knowing the spatial distribution of benthic habitats is also important from the coastal management point of view. Our previous results clearly demonstrated that remote sensing methods can be used to map water depth and distribution of taxonomic groups of benthic algae (e.g., red, green, and brown algae) in the optically complex coastal waters of the Baltic Sea. We have as well shown that benthic habitat mapping should be done at high spatial resolution owing to the small-scale heterogeneity of such habitats in Estonian coastal waters. Here we tested the capability of high spatial resolution hyperspectral airborne image in its application for mapping benthic habitats. A big challenge is to define appropriate mapping classes that are also meaningful from the ecological point of view. In this study two benthic habitat classification schemes—broader level and finer level—were defined for the study area. The broader level classes were relatively well classified, but discrimination among the units of the finer classification scheme posed a considerable challenge and required a careful approach. Benthic habitat classification provided the highest accuracy in the case of the Spectral Angle Mapper classification method applied to a radiometrically corrected image. Further processing levels, such as spatial filtering and glint correction, decreased the classification accuracy.

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

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

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

    Directory of Open Access Journals (Sweden)

    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.

    While secondary contact between Mytilus edulis and Mytilus trossulus in North America results in mosaic hybrid zone formation, both species form a hybrid swarm in the Baltic. Despite pervasive gene flow, Baltic Mytilus species maintain substantial genetic and phenotypic differentiation. Exploring mechanisms underlying the contrasting genetic composition in Baltic Mytilus species will allow insights into processes such as speciation or adaptation to extremely low salinity. Previous studies in the Baltic indicated that only weak interspecific reproductive barriers exist and discussed the putative role of adaptation to environmental conditions. Using a combination of hydrodynamic modelling and multilocus genotyping, we investigate how oceanographic conditions influence passive larval dispersal and hybrid swarm formation in the Baltic. By combining our analyses with previous knowledge, we show a genetic transition of Baltic Mytilus species along longitude 12°-13°E, that is a virtual line between Malmö (Sweden) and Stralsund (Germany). Although larval transport only occurs over short distances (10-30 km), limited larval dispersal could not explain the position of this genetic transition zone. Instead, the genetic transition zone is located at the area of maximum salinity change (15-10 psu). Thus, we argue that selection results in weak reproductive barriers and local adaptation. This scenario could maintain genetic and phenotypic differences between Baltic Mytilus species despite pervasive introgressive hybridization. © 2017 John Wiley & Sons Ltd.

    In this study of the Cambrian aquifer system(CAS) in the Baltic Artesian Basin(BAS) (, chemistry, stable isotopes, noble gas measurements, and dating tracers were combined for study the flow and recharge dynamics of the system over the last million years We find that the variability in chemical composition, stable isotopes and noble gas content in the basin is predominately controlled by mixing of three distinct water masses: Holocene and Pleistocene interglacial water, glacial meltwater, and brine. 81Kr is a nearly ideal dating tracer for such old systems. The radiogenic 4He and 40Ar provide additional information, but are more difficult to interpret in terms of groundwater age. In this study, we did not consider diffusive loss of 81Kr to stagnant water, which might result in an overestimation of groundwater ages ). However, the relatively high porosity and large thickness of the CAS, together with the presumed high salinity and low Kr content of the stagnant water all diminish the effect of diffusive 81Kr loss on age estimates. Our results confirm that under normal conditions, underground production of 81Kr is not affecting the dating results. 81Kr, 4He, and 40Ar all indicate a residence time of the brine of more than 1-3 Ma. Some uncertainty about the brine formation process remains, but the combination of chemical and stable isotope composition of the brine, noble gas concentrations and dating results favors evaporative enrichment of seawater. Tracer ages of interglacial water and glacial meltwater are on the order of several hundred thousand years, which means that several reversals of the flow direction in the CAS as a result of the paleoclimatology of the area have to be taken into account. Under such conditions, small vertical leakage, through fracture zones for example, might considerably impact the net flow pattern. Due to the cyclic flow direction reversals, the aquifer was probably in a transient state over most of the last 1 Ma period.

    Full Text Available This article is the first in a series of three describing the modelling of the vertical different photosynthetic and photoprotecting phytoplankton pigments concentration distributions in the Baltic and their interrelationsdescribed by the so-called non-photosynthetic pigment factor.The model formulas yielded by this research are an integral part of the algorithms used in the remote sensingof the Baltic ecosystem. Algorithms of this kind have already been developed by our team from data relating mainly to oceanic Case 1 waters (WC1 and have produced good results for these waters. But their application to Baltic waters, i.e.,Case 2 waters, was not so successful. On the basis of empirical data for the Baltic Sea, we therefore derived new mathematical expressions for the spatial distribution of Baltic phytoplankton pigments. They are discussed in this series of articles. This first article presents a statistical model for determining the total concentration ofchlorophyll, a (i.e., the sum of chlorophylls a+pheo derived spectrophotometrically at different depths in the Baltic Sea Ca(z on the basis of its surface concentration Ca(0,which can be determined by remote sensing. This model accounts for the principal features of the vertical distributions of chlorophyll concentrations characteristic of the Baltic Sea. The model's precision was verified empirically: it was found suitable for application in the efficient monitoring of the Baltic Sea. The modified mathematical descriptions of the concentrations of accessory pigments (photosynthetic and photoprotecting in Baltic phytoplankton and selected relationships between them are given in the other two articles in this series (Majchrowski et al. 2007, Woźniak et al. 2007b, both in this volume.

    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)

    Increasing dissolved organic carbon (DOC) concentrations in lakes, rivers and streams in northern mid latitudes have been widely reported during the last two decades, but relatively few studies have dealt with trends in DOC export. We studied the export of DOC from Finnish rivers to the Baltic Sea between 1975 and 2010, and estimated trends in DOC fluxes (both flow normalised and non-normalised). The study encompassed the whole Finnish Baltic Sea catchment area (301,000 km(2)) covering major land use patterns in the boreal zone. Finnish rivers exported annually over 900,000 t DOC to the Baltic Sea, and the mean area specific export was 3.5 t km(-2). The highest export (7.3t km(-2)) was measured in peat dominated catchments, whereas catchments rich in lakes had the lowest export (2.2 t km(-2)). Inter-annual variation in DOC export was high and controlled mainly by hydrology. There was no overall trend in the annual water flow, although winter flow increased in northern Finland over 36 years. Despite the numerous studies showing increases in DOC concentrations in streams and rivers in the northern hemisphere, we could not find any evidence of increases in DOC export to the northern Baltic Sea from Finnish catchments since 1975.

    For several hundred years, the Baltic German families of pharmacists have been the decisive creator of traditions in Latvian pharmacy. A large amount of the oldest pharmacies in Latvia, especially in Riga, were owned by pharmacists of Baltic German origin. Many of these ancient pharmacies ceased to exist in 1939, as a result of the emigration of the Baltic Germans. The agreement on the outward migration of German nationality citizens between Latvia and Germany was signed October 30, 1939. According to the information of the Pharmacy Board of Latvia, the number of employees in the pharmaceutical sector, registered in 1939, was 2068 persons. During the first wave of emigration, at the end of the year 1939, 306 persons, related to pharmacy, renounced the Latvian citizenship and emigrated. During the second wave of emigration, in spring of 1941, when Latvia had already lost its political independence, another 49 pharmaceutic employees left Latvia. In total 355 employees emigrated to Germany. As a result of the Baltic German emigration there was a decreased number of pharmacies in Latvia and the lack of pharmacists became a local issue. In rural areas quite often the only one pharmacy, which had been owned by a German origin pharmacist was liquidated or stayed closed for several months.

    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.

    1993-01-01

    Ignorance and failure to see natural processes for what they are is a growing problem in environmental debates. The Baltic is a typical example of discussions about marine pollution. In awareness of this problem, the author gives a detailed description of the hydrographical and hydrochemical conditions in the Baltic Sea before dealing exhaustively with the chemical behaviour of selected heavy metals (cadmium, copper, nickel, uranium, molybdenum, cobalt, iron, and manganese). Neither phytoplankton nor zooplankton nor higher organisms show signs of acute toxicity. A comparison between Baltic Sea water and drinking water in Kiel with regard to concentrations in both cases yields values well below the limit values of the Ordinance on Drinking Water. Heavy metal accumulation in fish is about equal to that in the North Sea. Sediment analyses confirm that heavy metal concentrations in the Baltic Sea have steadily rise over the past 100 years. At present it is not possible to answer questions on the environmental impact, that is, the chronic toxicity of these elements. (orig./UHE) [de

    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.

  15. Water circulation and recharge pathways of coastal lakes along the southern Baltic Sea in northern Poland

    Directory of Open Access Journals (Sweden)

    Cieśliński Roman

    2016-12-01

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

  1. Do toxic cyanobacteria blooms pose a threat to the Baltic ecosystem?

    Directory of Open Access Journals (Sweden)

    Hanna Mazur-Marzec

    2009-09-01

    Full Text Available Cyanobacteria, otherwise known as blue-green algae, are oxygenic, photosynthetic prokaryotes. They occur naturally in many fresh, marine and brackish waters worldwide and play an important role in global carbon and nitrogen cycles. In their long history, cyanobacteria have developed structures and mechanisms that enable them to survive and proliferate under different environmental conditions. In the Baltic Sea, the mass development of cyanobacteria is compounded by a high level of eutrophication. The dominant species in the Baltic, the filamentous Aphanizomenon flos-aquae and Nodularia spumigena, can fix dissolved atmospheric N2, as a result of which they can outcompete other phytoplankton organisms. Heterocystous, filamentous cyanobacteria also make a significant contribution to the internal nutrient loading in the Baltic. The blooms of N. spumigena are of particular concern, as this cyanobacterium produces nodularin (NOD, a hepatotoxic peptide. The concentration of the toxin in the sea is regulated mainly by dilution with uncontaminated water, photolysis, sorption to sediments and microbial degradation. The transfer of the toxin in the Baltic trophic chain through zooplankton, mussels, fish and birds has been reported, but biodilution rather than bioconcentration has been observed. Cyanobacterial blooms are thought to pose a serious threat to the ecosystem. Their harmful effects are related to the occurrence of a high biomass, oxygen depletion, a reduction in biodiversity, and the production of toxic metabolites.

  8. Long-term changes in the seasonality of Baltic sea level

    Susana M. Barbosa

    2016-06-01

    Full Text Available The seasonal cycle accounts for about 40% of the total sea level variability in the Baltic Sea. In a climate change context, changes are expected to occur, not only in mean levels but also in the seasonal characteristics of sea level. The present study addresses the quantification of changes in the seasonal cycle of sea level from a set of century-long tide gauge records in the Baltic Sea. In order to obtain robust estimates of the changes in amplitude and phase of the seasonal cycle, we apply different methods, including continuous wavelet filtering, multi-resolution decomposition based on the maximal overlap discrete wavelet transform, auto-regressive-based decomposition, singular spectrum analysis and empirical mode decomposition. The results show that all methods generally trace a similar long-term variability of the annual cycle amplitudes, and we focus on discrete wavelet analysis as the natural counterpart of classical moving Fourier analysis. In contrast to previous studies suggesting the existence of long-term changes in the seasonal cycle, in particular an increase of the annual amplitude, we find alternating periods of high and low amplitudes without any clear indication of systematic long-term trends. The derived seasonal patterns are spatially coherent, discriminating the stations in the Baltic entrance from the remaining stations in the Baltic basin, for which zonal wind accounts for typically more than 40% of the variations in amplitude.

    Yue O.O. Hu

    2016-05-01

    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.

    A better knowledge of sources, transport, reservoirs and fate of persistent organic pollutants (POPs) in the Baltic Sea environment is crucial for the identification of effective actions against these compounds. In this report the present situation regarding sources and current fluxes of persistent pollutants in the Baltic Sea ecosystem is presented. The compounds selected for the study were: polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), polychlorinated dibenzofurans (PCDFs) and polychlorinated dibenzo-p-dioxins (PCDDs). These classes of compounds represent a broad range of physical-chemical properties, and hence their environmental behaviour encompasses the spectrum of most chemicals listed in the Stockholm Convention. Based on current knowledge and some new field measurements in air, sea water and sediments, mass balances for the selected POPs were calculated. These mass balances indicate that the atmosphere is the major source of PCDD/Fs to the Bothnian Sea and the Baltic Proper and also the dominant external source of HCB and PCBs to the Baltic Sea. These findings emphasise the need for further international agreements to prevent long-range transboundary transport of these POPs

    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.

    Full Text Available This paper provides an overview of differences and similarities of the current climate changes in the Baltic and Adriatic coastal regions and appropriate adaptation policies on national, regional and European level. All reparian countries are at different stages of developing and implementing national adaptation strategies. The proposal for an overall BSR wide Climate Change Adaptation Strategy and Action Plan has been launched with the aim to recommend actions for climate change adaptation in the Baltic region. No similar agreement has been concluded yet on the protection of the semi-closed Adriatic Sea, the surface of which is about 1/2 of that of the Baltic Sea, and whose coastal region is home to about 1/4 of that of the Baltic Sea. The differences in the socio-economic characteristics and indicators may be partly responsible for the differring attitudes, actions and reporting concerning the adaptation to climate change, both between individual countries, as well as between the two regions as a whole

    Full Text Available The processing of terrestrial dissolved organic matter (DOM in coastal shelf seas is an important part of the global carbon cycle, yet, it is still not well understood. One of the largest brackish shelf seas, the Baltic Sea in northern Europe, is characterized by high freshwater input from sub-arctic rivers and limited water exchange with the Atlantic Ocean via the North Sea. We studied the molecular and isotopic composition and turnover of solid-phase extractable (SPE DOM and its transformation along the salinity and redox continuum of the Baltic Sea during spring and autumn. We applied ultrahigh-resolution mass spectrometry and other geochemical and biological approaches. Our data demonstrate a large influx of terrestrial riverine DOM, especially into the northern part of the Baltic Sea. The DOM composition in the central Baltic Sea changed seasonally and was mainly related to autochthonous production by phytoplankton in spring. Especially in the northern, river-dominated basins, a major fraction of riverine DOM was removed, likely by bio- and photo-degradation. We estimate that the removal rate of terrestrial DOM in the Baltic Sea (Bothnian Bay to the Danish Straits/Kattegat area is 1.6–1.9 Tg C per year which is 43–51% of the total riverine input. The export of terrestrial DOM from the Danish Straits/Kattegat area toward the North Sea is 1.8–2.1 Tg C per year. Due to the long residence time of terrestrial DOM in the Baltic Sea (total of ca. 12 years, seasonal variations caused by bio- and photo-transformations and riverine discharge are dampened, resulting in a relatively invariant DOM molecular and isotopic signature exported to the North Sea. In the deep stagnant basins of the Baltic Sea, the DOM composition and dissolved organic nitrogen concentrations changed seasonally, likely because of vertical particle transport and subsequent degradation releasing DOM. DOM in the deep anoxic basins was also enriched in sulfur

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

    Coastal areas are extremely vulnerable to impacts from changing marine conditions, which are increasingly being driven by human activity (e.g. nutrient cycling, salinity, hydrography, sea level, climate change). Recent research into the complex and dynamic cycling of carbon in many increasingly nutrient-enriched coastal systems has suggested that they have switched from being net C sources to net C sinks over the last 150 years. This study seeks to explore carbon sequestration rates over the last 150 years from several key regions across the coastal Baltic Sea by synthesising organic carbon (OC) inventories from multiple well-dated sedimentary records from Baltic coasts. Such data will provide insight into long-term coastal change and how terrestrial human impact is influencing the ecology and biogeochemistry of the Baltic Sea. To examine past and present rates of carbon burial in key coastal areas of the Baltic Sea, a synthesis of 30-40 sediment cores from across the Baltic Sea is presented here from Baltic Denmark, Germany, Latvia, western Sweden and southern Finland, and are primarily from near-shore and shallow fjord/estuarine sites. The majority of sites span the last 100-150 years and the majority (>75%) are independently dated using 210Pb. Unsupported 210Pb inventories also allow raw sedimentation rates to be corrected for sediment focussing, permitting regionally reliable estimates of OC accumulation rates to be calculated and provide a plausible basis for upscaling OC accumulation rates within these key regions of the Baltic. Preliminary data analyses suggest a major step-change in system behaviour during the 20th century following low, stable ( 10 g OC m-2 yr-1 focussing corrected, OCFC) rates pre-1900. The initial rise in burial rates occurs early in the 1900s though is punctuated by a slight fall during the 1930s/1940s. After 1950, burial rates dramatically rise (consistently up to 45 g OCFC m-2 yr-1; 4 x pre-1900 rates), a pattern which is repeated

    Full Text Available The article is aimed at determining the feasibility and elaborating a strategiology of formation of the Baltic-Black Sea transnational techno-resource corridor in the context of the activation and implementation of the financial and economic cells, including investment, of growth in the European region on the basis of management by objective and targeted involvement of investment platforms at maritime boundaries (Gdansk, Odessa. It has been substantiated that formation of the Baltic-Black Sea transnational techno-resource corridor will strengthen Ukraine’s position in the European region and also enhance the European Union’s importance in the European-Atlantic space. For the first time, the functional (financial-economic difference between the proposed techno-resource corridor and the existing technological, transport, and financial corridors has been inherently disclosed. The socio-economic advantages of formation of this corridor at the level of both the two States (Poland, Ukraine and the individual economic entities together with the population have been presented. The targeted formation of the indicated techno-resource corridor on the basis of of management by objective will ensure a qualitative reorientation of the national economy and quantitative financial returns, proceeding from the rational use of both available resources and the untapped potentials of economic agents and territories.

    Full Text Available Biozones of the East Baltic Early Ordovician trilobites were studied based on the trilobite distribution in northwestern Russia, Estonia, and Sweden. New data on trilobite distribution reveal the diachroneity of the lowest calcareous sediments of the Mäeküla Member, which forms the upper part of the Leetse Formation in the East Baltic. Trilobites of the Tremadoc Apatokephalus serratus and Megistaspis (Ekeraspis armata biozones are missing in the East Baltic, in contradiction to the suggestion of Balashova (Vopr. Paleontol., 1966, 5, 3–22. Some poorly preserved specimens probably belonging to Megistaspis (Paramegistaspis planilimbata (Angelin and also records of Pliomerops? linnarssoni (Wiman indicate that the Arenig Megistaspis (P. planilimbata Biozone of the Hunneberg Stage may be represented in some localities. The final delimitation of biozones in the Mäeküla and Päite members should improve when the ontogenetic and phylogenetic variation of the M. (Paramegistaspis lineage has been fully documented. Until then the Evropeites lamanskii Biozone is used in the East Baltic following Balashova, as indicated by the appearance of that taxon in most studied localities, marking the beginning of the Billingen Age. The succeeding Megalaspides (Megalaspides dalecarlicus Biozone is represented by the occurrence of at least its upper part in the Vassilkovo Beds in the St. Petersburg region, where Megalaspides paliformis Tjernvik occurs together with the index taxon (these taxa co-occur in the upper part of this zone in Sweden. The Päite Member in the East Baltic is correlated with the Megistaspis (P. estonica Biozone of the upper part of the Billingen Stage in Sweden.

    Long-term oxygen and nutrient transports in the Baltic Sea are reconstructed using the Swedish Coastal and Ocean Biogeochemical model (SCOBI) coupled to the Rossby Centre Ocean model (RCO). Two simulations with and without data assimilation covering the period 1970-1999 are carried out. Here, the weakly coupled scheme with the Ensemble Optimal Interpolation (EnOI) method is adopted to assimilate observed profiles in the reanalysis system. The reanalysis shows considerable improvement in the simulation of both oxygen and nutrient concentrations relative to the free run. Further, the results suggest that the assimilation of biogeochemical observations has a significant effect on the simulation of the oxygen-dependent dynamics of biogeochemical cycles. From the reanalysis, nutrient transports between sub-basins, between the coastal zone and the open sea, and across latitudinal and longitudinal cross sections are calculated. Further, the spatial distributions of regions with nutrient import or export are examined. Our results emphasize the important role of the Baltic proper for the entire Baltic Sea, with large net transport (export minus import) of nutrients from the Baltic proper into the surrounding sub-basins (except the net phosphorus import from the Gulf of Riga and the net nitrogen import from the Gulf of Riga and Danish Straits). In agreement with previous studies, we found that the Bothnian Sea imports large amounts of phosphorus from the Baltic proper that are retained in this sub-basin. For the calculation of sub-basin budgets, the location of the lateral borders of the sub-basins is crucial, because net transports may change sign with the location of the border. Although the overall transport patterns resemble the results of previous studies, our calculated estimates differ in detail considerably.

    Full Text Available BACKGROUND: Estonia, Latvia and Lithuania joined the EU in 2004 and had to increase tobacco excise rates. The aim of the paper is to explore the impact of tax policies on tobacco consumption, revenue and tobacco market in the Baltic countries.METHODS: Data on tobacco sales, tax rates, prices, revenues, and smoking prevalence were taken from databases and reports. Tobacco affordability index was calculated using data on prices and GDP. RESULTS: Tobacco taxation policy had three similar stages in Baltic countries: (1 In 2004-2007, tax rates increased slowly and cigarettes became more affordable in years of economic boom. Tobacco consumption and smuggling out of Baltic countries was on the rise, which caused increase of sales and revenues. (2 In 2008-2009, Baltic countries had to hike excise and VAT rates in years of economic recession, which caused sharp decline of cigarette affordability and resulted in large decline of consumption and sales and some excise revenue downfall in 2009-2010; however, all countries had higher revenues in 2010 than in 2007. (3 In 2011, economic situation improved and tobacco sales and revenue increased. The tobacco taxation policy in Baltic countries in 2004-2011 resulted in: (1 decline of total (licit + illicit annual cigarette consumption by 30% both in Latvia and Lithuania, and by 10% in Estonia; (2 decline of daily smoking prevalence by 10-20%; (3 decline of the out-of-country smuggling; (4 almost no changes in volumes of smuggling into Lithuania and Estonia; (5 three-fold increase of the annual tobacco revenues in three countries combined.CONCLUSIONS: Decrease of tobacco affordability caused by tax hikes and economic recession was the key factor of tobacco consumption decline. Tobacco tax hike is a win-win policy, while in years of economic boom it has more fiscal benefits and in years of economic recession it has more public health benefits.

    The residues from human environments often contain antibiotics and antibiotic resistance genes (ARGs) that can contaminate natural environments; the clearest consequence of that is the selection of antibiotic-resistant bacteria. The Baltic Sea is the second largest isolated brackish water reservoir on Earth, serving as a drainage area for people in 14 countries, which differ from one another in antibiotic use and sewage treatment policies. The aim of this study was to characterize the bacterioplankton structure and quantify ARGs (tetA, tetB, tetM, ermB, sul1, blaSHV, and ampC) within the bacterioplankton community of the Baltic Sea. Quantitative polymerase chain reaction was applied to quantify ARGs from four different sampling sites of the Baltic Sea over 2 years, and the bacterial communities were profiled sequencing the V6 region of the 16S rRNA gene on Illumina HiSeq2000. The results revealed that all the resistance genes targeted in the study were detectable from the Baltic Sea bacterioplankton. The percentage of tetA, tetB, tetM, ermB, and sul1 genes in the sea bacterial community varied between 0.0077% and 0.1089%, 0.0003% and 0.0019%, 0.0001% and 0.0105%, 0% and 0.0136%, and 0.0001% and 0.0438%, respectively. The most numerous ARG detected was the tetA gene and this gene also had the highest proportion in the whole microbial community. A strong association between bacterioplankton ARGs' abundance data and community phylogenetic composition was found, implying that the abundance of most of the studied ARGs in the Baltic Sea is determined by fluctuations in its bacterial community structure. © 2013 International Union of Biochemistry and Molecular Biology, Inc.

    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.

    The ecological status of the Baltic Sea has for many years been affected by the high input of both waterborne and airborne nutrients. The focus here is on the airborne input of nitrogen (N) and the projected changes in this input, assuming the new National Emission Ceilings directive (NEC-II), currently under negotiation in the EU, is fulfilled towards the year 2020. With a set of scenario simulations, the Danish Eulerian Hemispheric Model (DEHM) has been used to estimate the development in nitrogen deposition based on present day meteorology combined with present day (2007) or future (2020) anthropogenic emissions. Applying a so-called tagging method in the DEHM model, the contribution from ship traffic and from each of the nine countries with coastlines to the Baltic Sea has been assessed. The annual deposition to the Baltic Sea is estimated to 203 k tonnes N for the present day scenario (2007) and 165 k tonnes N in the 2020 scenario, giving a projected reduction of 38 k tonnes N in the annual load in 2020. This equals a decline in nitrogen deposition of 19%. The results from 20 model runs using the tagging method show that of the total nitrogen deposition in 2007, 52% came from emissions within the bordering countries. By 2020, this is projected to decrease to 48%. For some countries the projected decrease in nitrogen deposition arising from the implementation of the NEC-II directive will contribute significantly to compliance with the reductions agreed on in the provisional reduction targets of the Baltic Sea Action Plan. This underlines the importance of including projections like the current in future updates of the Baltic Sea Action Plan.

  17. THE GREGARIOUS BEHAVIOR OF INVESTORS FROM BALTIC STOCK MARKETS

    2015-07-01

    Full Text Available The main objective of this research is to investigate market participants’ gregarious behaviour in Baltic stock markets, namely Lithuania, Latvia and Estonia during the period January 2003-December 2013. The herding behaviour derives from the investors’ irrationality, who trade financial assets based on their positive expectations about prices future growth, generating manias among other market participants, thus ignoring the real return rates and the risk levels of their investments.The investors’ irrational behaviour is influenced by actions, feelings and impulses that are intertwined: mimicry, fear, trust, greed, optimism, pessimism, euphoria, panic. These features highlight an erroneous perception of investors in point of unsustained increase in prices, which has been generated by the stock prices deviations from their fundamental value.Under these premises, optimism, overreaction and speculative bubbles are appearing on the market and may constitute triggering factors of a financial crash.The probability of the occurrence of the speculative bubbles and financial crashes is influenced by the continuous entry on the market of new investors and less informed participants, which often act based on impulse, following a benchmark, without considering their own analysis and information that they hold. The existence of a “collective behaviour” of the investors, which is manifested by their tendency to imitate other market participants actions and to “follow the herd”, so ignoring their own beliefs, may increase market sensitivity to shocks and the probability of the occurrence of the systemic risk.In order to identify the investors’ herding behaviour, I have applied an adjusted CSSD model proposed by (Yao, Ma, Peng He, 2014, which implies the inclusion of two additional variables, the first one, to reduce the effect of multicollinearity and a second one, a lag term of the dependent variable, in order to improve the power of the

  18. Azimuthal and Radial Seismic Anisotropy Beneath the Baltic Shield

    The SVEKALAPKO passive seismic array in Finland provides us with an exceptional opportunity to study seismic anisotropy in and below the lithosphere in a shield. The array was composed of almost 150 sensors - out of which 46 were broadband - in a regular 2D grid which facilitated high-quality array analysis. We analyse phase velocities of both Love and Rayleigh waves to constrain radial and azimuthal anisotropy. We invert for the anisotropic parameters ξ and Gc on the one hand, and for the percentage of aligned olivine on the other. This latter parametrization of the inverse problem makes it straightforward to quantitatively compare the radial and the azimuthal anisotropies, under the assumption that aligned olivine dominates the anisotropy. The radial anisotropy, for which we have resolution in the lithosphere only, is strong, and can be explained by 40%-60% of the rock being olivine with the a-axis in the horizontal plane, equivalent to values of ξ between 1.09 and 1.14. This radial anisotropy is stronger than observed in shield areas in global models (e.g. Beghein and Trampert, 2004). The azimuthal anisotropy is on the contrary very small in the lithosphere. This indicates that the orientation of the olivine minerals is random within the horizontal plane or that the overall effect across the area is negligible due to different orientations in different domains. Results from body-waves (Plomerová et al., 2005, Vecsey et al., in prep.) would support the latter interpretation. The azimuthal anisotropy as estimated by Rayleigh wave analysis is on the contrary significant below 200-250km depth, and corresponds to approximately 15%-20% of the rock being olivine with the a-axis aligned in direction N20. Xenolith analysis in the area shows that the rheologic lithosphere is at most 250km thick, so we suggest that this observed anisotropy is sub-lithospheric. Interestingly, the fast direction is significantly different from the absolute plate motion of the Baltic

    The Baltic Sea is especially susceptible to multiple human impacts due to its estuarine mixing patterns and long water residence times. Temporally and spatially, it is one of the best investigated marginal seas worldwide allowing for a deep knowledge of natural and human processes forming this unique brackish ecosystem. In this presentation, we shortly summarize the physical, biogeochemical and ecological settings of the Baltic Sea and address major human drivers and pressures threatening its ecosystem. Further, we summarize the scientific and political efforts that led to the formulation of Baltic Sea Action Plan, a milestone for eutrophication management and European environmental governance. Further, we summarize the efforts and societal pitfalls towards an Ecosystem Based Fisheries Management, strategies to decrease loads of environmental pollutants and management of marine biodiversity/habitat issues in the unique Baltic Sea context.
