This book describes the marine ecosystem of the Barents Sea, located north of Norway and Russia as part of the Arctic Ocean. Basic knowledge is presented about components of the ecosystem from virus and bacteria via plankton and fish to seabirds through to marine mammals and their interactions with the physical environment. Ecosystem dynamics are given a prominent role in the book. Mathematical models of the plankton and important fish stocks are employed to help elucidate the interplay between populations and trophic levels. The situation regarding contaminants is reviewed, as is the newly established Norwegian plan for the management of the Barents Sea. The impact of global warming is also discussed. Ecosystem Barents Sea is written for all those with an interest in marine ecology in the arctic seas, including research institutes, governmental ecosystem management units, and natural resources organizations.

Where and what is the Arctic? What animals live there, and how are they distributed? How do they cope with cold in their austere environment, and how can Arctic mammals survive birth when it is 40 degrees below freezing. How can seals dive to a depth of 1000 metres and stay submerged for more than an hour, and how does complete darkness in winter affect the inhabitants of the high Arctic? This book answers these questions and also gives an introduction to the Arctic. It is based on the author's 40 years of experience in the Arctic, its environment and animal life. As this book contains almost 200 illustrations and deals with the entire Arctic animal kingdom, it will be suitable as a textbook for courses in Arctic biology, and also serve specialists in the field. It is a reference book and a source of information about published original literature.

Marine mammals command a high level of public attention, reflected in specific legislation for their protection and management in many countries. They also present particular challenges to ecologists and conservation biologists. They are mostly difficult to observe, they occupy an environment that is vast in its three dimensional extent, there are often perceived conflicts between marine mammals and people, and furthermore several species are now close to extinction. Marine mammals have some intriguing features in their biology - the ability to dive to crushing depths, to perform breath-hold dives that defy our current understanding of mammalian physiology, and many have an ability to hunt down prey using sophisticated sonar that we are only just beginning to understand. Many species also have complex social structures. We still have much to learn about these extraordinary animals so a comprehensive and authoritative overview of current methodology is now timely. The intention of this book is both to summarize the state-of-the-art and to encourage innovation and further progress in this research field.

Marine mammals hold a special position in the hearts of people inhabiting Nordic Arctic areas and in coastal communities around the North Atlantic Ocean as they are an essential part of the diet and traditional life-style. However, marine mammals are in a particularly vulnerable position as regards environmental pollutants, because of the large fat stores in their bodies which serve as a "magnet" to a large number of persistent and toxic pollutants. A Nordic Council of Ministers supported collaboration between Norway, Denmark/Greenland, Faroe Island, Iceland and Sweden set out to look for possible trends in "new" contaminants in marine mammals in Nordic Arctic waters. The "new" contaminants in focus are the brominated flame retardants including the PBDEs, methoxylated PBDEs, perfluorinated compounds including the PFOS family, and polychlorinated naphthalenes. In addition, a subset of the samples was analysed for brominated dioxins and dibenzofurans. The marine mammals studied were fin whale, minke whale, pilot whale, white-sided dolphins, harbour porpoise, ringed seal and hooded seal. The study aims at giving a wide scope of the presence of these "new" contaminants in marine mammals in recent time and going back to the 1980s using samples from specimen banks.
