Book Description
The book gives an overview of the tectonic, geological, potential fields, etc maps of the Arctic that were compiled during geological and geophysical studies conducted in the Arctic over the past 15 years under the International project “Atlas of Geological Maps of the Circumpolar Arctic at a scale of 5M” and presents the results of geological, geophysical, paleogeographic and tectonic studies carried out in the Arctic Ocean and the Eastern Arctic during the implementation of national mapping and scientific programmes and studies intended to provide scientific substantiation for the extension of the continental shelf (ECS). Given its scope, the book will appeal to a wide range of geologists.

Book Description
The 5-year Circum-Arctic Lithosphere Evolution (CALE) program developed new constraints on the tectonic history of the central Amerasia basin of the Arctic Ocean. This volume is the final synthesis of the CALE program, which brought together an international team of scientists to develop integrated, multi-disciplinary understanding of the region. This approach, based on the integration of much new geological and geophysical data from onshore and offshore , is necessary to advance our understanding of this basin. Regional onshore-to-offshore transects are central to the 18 papers in this volume. The diverse science supporting these crust-to-mantle regional transects includes structural, geochronological, isotopic, potential fields, and seismic reflection and refraction data. Four chapters present circum-Arctic investigations by the regional CALE teams. The final chapter addresses pan-Arctic themes. This unique collaboration, relying on new data and new syntheses of existing data sheds new light on the history of the Arctic Ocean.

Book Description
The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered.

Book Description
Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments. Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled.*Aimed at specialists and graduates *Presents background research, recent developments, and future trends*Written by a leading scholar and industry expert

Book Description
The mountains and fjords of Greenland preserve a record of nearly four billion years of Earth history -- a story of mountain building, volcanic eruptions, primitive life and ice ages. During this vast period of time, through processes of continental drift, Greenland has journeyed from the southern hemisphere through the tropics to its present polar position. This volume presents an account of the geological evolution of Greenland, together with its mineral wealth and hydrocarbon potential. It is written in a form that is aimed at the general reader with an interest in the dramatic history of our planet.

Book Description
In one hundred years, or even fifty, the Arctic will look dramatically different than it does today. As polar ice retreats and animals and plants migrate northward, the arctic landscape is morphing into something new and very different from what it once was. While these changes may seem remote, they will have a profound impact on a host of global issues, from international politics to animal migrations. In Future Arctic, journalist and explorer Edward Struzik offers a clear-eyed look at the rapidly shifting dynamics in the Arctic region, a harbinger of changes that will reverberate throughout our entire world. Future Arctic reveals the inside story of how politics and climate change are altering the polar world in a way that will have profound effects on economics, culture, and the environment as we know it. Struzik takes readers up mountains and cliffs, and along for the ride on snowmobiles and helicopters, sailboats and icebreakers. His travel companions, from wildlife scientists to military strategists to indigenous peoples, share diverse insights into the science, culture and geopolitical tensions of this captivating place. With their help, Struzik begins piecing together an environmental puzzle: How might the land’s most iconic species—caribou, polar bears, narwhal—survive? Where will migrating birds flock to? How will ocean currents shift? And what fundamental changes will oil and gas exploration have on economies and ecosystems? How will vast unclaimed regions of the Arctic be divided? A unique combination of extensive on-the-ground research, compelling storytelling, and policy analysis, Future Arctic offers a new look at the changes occurring in this remote, mysterious region and their far-reaching effects.
