Book Description
The North Sea, one of the most intensively used sea-areas in the world, may well be one of the most intensively regulated sea-areas as well. As human activity developed in the North Sea national & later international regulations followed these developments. The result has been what is commonly called a piecemeal approach. The legal regime of the North Sea has developed in an incremental manner. Thus one conventional instrument after the other, covering different user-functions like vessel-source pollution, fisheries, ocean dumping & land-based pollution, was adopted. In contrast to more modern approaches these legal instruments have their own framework. The result is that the instruments are scattered in many different documents, & even for the more well informed North Sea watcher it is difficult to obtain a comprehensive overview of the regulatory instruments. The North Sea: Basic Legal Documents on Regional Environmental Co-operation offers a comprehensive view of the instruments dealing with all sources of marine pollution in the North Sea, be they ocean dumping, land-based pollution or vessel-source pollution. The book contains many legal documents, including maps & tables. It also contains non-conventional instruments such as the texts of the declarations of the International North Sea Conferences, held between 1984 & 1990, & recommendations & decisions of e.g. the Paris Commission on Land-Based Pollution & the Oslo Commission on Dumping. Furthermore the book contains documentation on relatively new areas of environmental concern in the North Sea region, i.e. nature conservation & management of living resources. The book supplements The North Sea: Perspectives on Regional Environmental Co-operation also edited by David Freestone & Ton IJlstra which contains 26 essays on legal & policy aspects of environmental protection in the North Sea.

Book Description
This is the first book to provide assessments of multidecadal changes in resources and environments of the Large Marine Ecosystems (LMEs) of the North Atlantic. Using the case study method, researchers examine the forces driving the changes and actions underway aimed at turning the corner from declining trends in biomass yields, toward recovery of depleted species populations and improvements in ecosystem integrity. Recently a distinguished group of 24 scientists argued eloquently that a new Sustainability Science was emerging that was focused on "meeting fundamental human needs while preserving the life support systems of planet Earth". The contributions contained in this volume are at the cutting edge of Sustainability Science and the results presented by the contributors are pertinent to one of the core questions: "How are long-term trends in environment and development, including consumption and population, reshaping nature-society interactions in ways relevant to sustainability?" (Science Vol. 292, 27 April 2001). The case studies demonstrate the utility of an ecosystem-based approach to the assessment and management of biomass yields and species sustainability. Movements toward ecosystem-based management have emerged from the case studies on the initiation of recoveries of several depleted groundfish stocks of the US Northeast Shelf LME; the collapse of the Newfoundland-Labrador Shelf cod; the assessment of physical and biological changes on the Scotian Shelf, West Greenland Shelf, Iceland Shelf LME, and the Faroe Plateau, the North Sea, and the Barents Sea LMEs. Uncertainties, with regard to environmental and human-generated forcing, are addressed in assessment of the states of the Iberian Coastal and Biscay-Celtic LMEs, and in broad-scale studies of the influences at the base of the food chain of climatic variability on the productivity and biodiversity of plankton communities of the North Atlantic. The volume concludes with an insightful perspective on the approaches used and the results reported by the eminent marine scientist and former President of ICES, Professor Gotthilf Hempel.

Book Description
This preface is being written at a time of exceptional public interest in the North Sea, following media head lines on toxic algal blooms, the mass mortality of common seals, and concern over pollution levels. These headlines may suggest that pollution of the North Sea is a recent event. This is not the case. Although no data are available (methods simply did not exist), it is safe to assume that emission (both into air and water) of heavy metals already started to increase in the 19th cen tury. The growth of cities and introduction of sewer sys tems led to the discharge of raw sewage and sewage sludge. The introduction of man-made (xenobiotic) organ ic chemicals and their subsequent emission into the North Sea commenced before the second world war. The shallower and coastal areas of the North Sea receive the highest concentrations of these pollutants. Not unexpectedly, these areas - some Norwegian fjords, the Dutch coast, the German Bight - show signs of ecosystem deterioration and eutrophication. A certain percentage of the pollutants does not remain in the North Sea but is "exported" to the Atlantic. The North Sea therefore con tributes to the global input of pollutants to the world's oceans. The major part of the pollutants accumulate in the North Sea and are incorporated in the bottom sediments. Although they are "out of sight", they should not be "out of mind".

Book Description
This volume contains the proceedings of the International Sym posium on North Sea Dynamics which was held in Hamburg, August 31 - September 4, 1981. More than 150 participants from 10 coun tries were present at the Symposium. Of the 58 lectures given, 45 are printed in this book. The manuscripts were reviewed by an international advisory board. The main goal of the organizers was to bring together as many active researchers as possible in this very general field of North Sea dynarnics, transcending the boundaries of the countries and the various disciplines involved, in order to discuss the main problems and future trends. In the ten years since the last comparable meeting in Aviemore, Scotland, several large interna tional experiments (JONSDAP '73 and '76, JONSWAP '73, '75 and '77, MARSEN '79) and new developments in modelling promised a rewarding exchange of ideas. In addition to the physical disci plines, biologists and geologists are increasingly able to pre sent quantitative analyses.
