For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system. 110,000 to 140,000 tons of phosphorus per year are added to the system from land uplift, in comparison to the 30,000 tons of phosphorus per year from rivers.

The present text compiles the latest research within the field of biology performed in the Baltic Sea area. The themes span from theoretical and philosophical aspects of the ecosystem concept over population and autecological studies to detailed descriptions of plant and animal physiology. Results from microcosm and mesocosm experiments as well as direct observations in field together bring insight of the special structure and function of the Baltic Sea ecosystem. How the spawning success of cod and spat are dependent of each other and environmental factors, the impact of alien species to the composition of plankton or benthic communities, the flip of phytobenthic to planktonic communities in lagoons and mechanisms triggering the change, pure descriptions of e.g. the Estonian coast and shallow off shore areas as well as strategies for the reproductive success of Fucus vesiculosus, and the influence of eutrophication of the different Baltic Sea areas and the fate of pollutants as radionucleids and PAH etc. and other themes are all discussed in the 24 original papers of this volume.

Marine resources and fish stocks are now high on the international and economic research agendas, and the management of highly complex marine ecosystems is increasingly important. The task is complicated by the number of interlinked factors to be taken into account, such as social impacts, drainage systems, marine currents and the ecosystems involved. This interdisciplinary volume presents a comprehensive blueprint for managing a sea. Focused on the Baltic Sea, it employs a range of methods and techniques, including nutrient budgets and simulation models, Geographical Information Systems (GIS), economic valuation and policy analysis, to arrive at an assessment of causes and consequences of pollution in the sea and the management of its resources. From the analysis of data on land use, population, costs of nutrient reductions and associated impacts, it presents significant and highly practical empirical and policy results. It diagnoses the causes of marine degradation, identifies through the use of simulation models cost-effective strategies for remediation and sets out the policies to be pursued collectively by the countries around the sea to restore and manage their common resource. This is an exemplary study in the application of ecological economics to complex natural resource systems. It will be of interest to students, researchers and professionals working on any aspect of marine ecosystem management.

Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Following this, a series of chapters written by scientific leaders worldwide synthesizes the problems and offers solutions for specific issues graded within the framework of the socio-economic-environmental mosaic. These include fisheries, climate change, coastal megacities, evolving human-nature interactions, remediation measures, and integrated coastal management. The problems faced by half of the world living near coasts are truly a worldwide challenge as well as an opportunity for scientists to study commonalities and differences and provide solutions. This book is centered around the proposed DAPSI(W)R(M) framework, where drivers of basic human needs requires activities that each produce pressures. The pressures are mechanisms of state change on the natural system and Impacts on societal welfare (including well-being). These problems then require responses, which are the solutions relating to governance, socio-economic and cultural measures (Scharin et al 2016). Covers estuaries and coastal seas worldwide, integrating their commonality, differences and solutions for sustainability Includes global case studies from leading worldwide contributors, with accompanying boxes highlighting a synopsis about a particular estuary and coastal sea, making all information easy to find Presents full color images to aid the reader in a better understanding of details of each case study Provides a multi-disciplinary approach, linking biology, physics, climate and social sciences

This edited volume presents a comprehensive and coherent interdisciplinary analysis of challenges and possibilities for sustainable governance of the Baltic Sea ecosystem by combining knowledge and approaches from natural and social sciences. Focusing on the Ecosystem Approach to Management (EAM) and associated multi-level, multi-sector and multi-actor challenges, the book provides up-to-date descriptions and analyses of environmental governance structures and processes at the macro-regional Baltic Sea level. Organised in two parts, Part 1 presents in-depth case studies of environmental governance practices and challenges linked to five key environmental problems - eutrophication, chemical pollution, overfishing, oil discharges and invasive species. Part 2 analyses and compares governance challenges and opportunities across the five case studies, focusing on governance structures and EAM implementation, knowledge integration and science support, as well as stakeholder communication and participation. Based on these cross-case comparisons, this book also draws a set of general conclusions on possible ways of improving the governance of the Baltic Sea by promoting what are identified as vital functions of environmental governance: coordination, integration, interdisciplinarity, precaution, deliberation, communication and adaptability.

During recent decades, large-scale effects of pollution on marine estuaries and even entire enclosed coastal seas have become apparent. One of the first regions where this was observed is the Baltic Sea, whereby the appearance of anoxic deep basins, extensive algal blooms and elimination of top predators like eagles and seals indicated effects of both increased nutrient inputs and toxic substances. This book describes the physical, biochemical and ecological processes that govern inputs, distribution and ecological effects of nutrients and toxic substances in the Baltic Sea. Extensive reviews are supplemented by budgets and dynamic simulation models. This book is highly interdisciplinary and uses a systems approach for analyzing and describing a marine ecosystem. It gives an overview of the Baltic Sea, but is useful for any marine scientist studying large marine ecosystems.

The first comprehensive overview of the enormous ecological diversity of Baltic coastal ecosystems is presented in this volume provides. A short introduction into the Baltic Sea as a reference ecosystem is followed by detailed descriptions of the characteristics of coastal ecosystems. Ecological case studies from four regions illustrate the different reactions of these ecosystems to natural and anthropogenic influences.
