Jan Mayen is a volcanic island surrounded by the deep Greenland, Iceland and Norwegian Seas. There, atmospheric and oceanic processes unleash potential energy that forces very dynamic interactions between sea and air. This unique geophysical focal point generates climatic variability in northern Europe, and supports marine biological production that sustains the yield of large living resources. The marine populations are clearly fluctuating with variations in climate, and raises questions about effects of man-made climate change. Since the last Ice Age the sinking of Greenland Sea Deep-Water has been a substantial driving force for the Global Thermo-Haline Circulation which feeds warm Atlantic water into the Nordic Seas. Global warming may interact with the deep-water formation and force feedback mechanisms that express themselves beyond imagination. The book addresses such problems to raise an interest for doing research on the island and in its waters. The potentials for doing that increases when the island's Loran-C station closes down in 2005. The book recommends how the international scientific community may gain access to this really challenging arena for local, regional and Global research. It is a blueprint for the logistics required for science to succeed in a very remote and physically demanding place on Earth.

Internationally important seabird resources are found in the Nordic countries (Greenland, Faeroes, Iceland, Jan Mayen, and Svalbard). To fulfill a recommendation of the Arctic Nordic Action Plan 1999, a project was carried out to harmonize databases for seabird colonies. Number of seabird species in these countries is 30, the number of colony sites may be 10,000, often more than one species at same site, and the total breeding pairs is estimated c. 50 million. A harmonized database format for seabird colonies was established, with 3 main tables, colony descriptions, colony survey data, study plot information. Linked are tables with references, observers, and photo documentation. The program can be downloaded free from: ftp://ftp.npolar.no/Out/Hallvard/. The manual is in the report appendix. The format harmonization is the first step in work on seabird colony databases. Harmonization enables common analyses over larger regions than hitherto possible, e.g. scientific assessments of species (colony details, geographic location, colony size, trend data, etc.) and conservation status overviews. Seabird colony data need to be incorporated into conservation policies. The databases are only as good as the data stored, many colonies remain unregistered, not censused, and fieldwork needs to be intensified. Each country maintains, updates, and corrects their databases, adding details lacking (habitat type, colony distribution, conservation status, land ownership, etc.).

In this book the eminent authors analyse the ice cover variability in the Arctic Seas during the 20th and early 21st centuries. In the first two chapters, they show that multi-year changes of the sea-ice extent in the Arctic Seas were formed by linear trends and long-term (climatic) cycles lasting about 10, 20 and 60 years. The structure of temporal variability of the western region (Greenland – Kara) differs significantly from the eastern region seas (Laptev and Chukchi). In the latter region, unlike the former area, relatively short-period cycles (up to 10 years) predominate. The linear trends can be related to a super-secular cycle of climatic changes over about 200 years. The most significant of these cycles, lasting 60 years, is most pronounced in the western region seas.

The Arctic is often portrayed as being isolated, but the reality is that the connectivity with the rest of the planet is huge, be it through weather patterns, global ocean circulation, and large-scale migration patterns to name but a few. There is a huge amount of public interest in the ‘changing Arctic’, especially in terms of the rapid changes taking place in ecosystems and exploitation of resources. There can be no doubt that the Arctic is at the forefront of the international environmental science agenda, both from a scientific aspect, and also from a policy/environmental management perspective. This book aims to stimulate a wide audience to think about the Arctic by highlighting the remarkable breadth of what it means to study its ecology. Arctic Ecology seeks to systematically introduce the diverse array of ecologies within the Arctic region. As the Arctic rapidly changes, understanding the fundamental ecology underpinning the Arctic is paramount to understanding the consequences of what such change will inevitably bring about. Arctic Ecology is designed to provide graduate students of environmental science, ecology and climate change with a source where Arctic ecology is addressed specifically, with issues due to climate change clearly discussed. It will also be of use to policy-makers, researchers and international agencies who are focusing on ecological issues and effects of global climate change in the Arctic. About the Editor David N. Thomas is Professor of Arctic Ecosystem Research in the Faculty of Biological and Environmental Sciences, University of Helsinki. Previously he spent 24 years in the School of Ocean Sciences, Bangor University, Wales. He studies marine systems, with a particular emphasis on sea ice and land-coast interactions in the Arctic and Southern Oceans as well as the Baltic Sea. He also edited a related book: Sea Ice, 3rd Edition (2017), which is also published by Wiley-Blackwell.

In the cold waters of the North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species--the North Atlantic right whale. This book is a history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon.

During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth.

Svalbard and Jan Mayen are two remote archipelagos located in the Arctic Ocean, administered by Norway. Svalbard is the larger of the two and is home to around 2,500 residents, mostly in the main settlement of Longyearbyen. Despite its harsh climate and isolation, the archipelago is known for its stunning natural beauty and unique wildlife, including polar bears, reindeer, and a wide range of bird species. Svalbard is also an important center for Arctic research, with numerous research stations and institutes studying topics such as climate change, geology, and biology. Jan Mayen, on the other hand, is an uninhabited volcanic island located farther to the northeast. Roughly 7,000 tourists visit the island annually, mostly for its rugged landscapes and opportunities for adventure sports such as hiking and kayaking. The island is also home to a weather station and a small military presence, as it serves as an important part of Norway's territorial claim in the Arctic. Despite its isolation and challenging conditions, Svalbard and Jan Mayen remain important symbols of Norway's northern heritage and an ongoing subject of scientific and cultural fascination.

The current warming trends in the Arctic may shove the Arctic system into a seasonally ice-free state not seen for more than one million years. The melting is accelerating, and researchers were unable to identify natural processes that might slow the deicing of the Arctic. Such substantial additional melting of Arctic and Antarctic glaciers and ice sheets would raise the sea level worldwide, flooding the coastal areas where many of the world's population lives. Studies, led by scientists at the National Center for Atmospheric Research (NCAR) and the University of Arizona, show that greenhouse gas increases over the next century could warm the Arctic by 3-5°C in summertime. Thus, Arctic summers by 2100 may be as warm as they were nearly 130,000 years ago, when sea levels eventually rose up to 6 m higher than today.
