There is broad agreement in the scientific community that the solid earth beneath the Arctic Ocean basin contains answers to major unsolved problems in the earth sciences and that many of these pertain to questions that are of global scientific significance or pressing societal concern. Recent political and technological developments, including the end of the Cold War and the prospective availability of nuclear submarines and powerful icebreakers for use as research platforms, appear to provide remedies for formidable obstacles of communication and access in harsh environmental conditions. This book recommends that the Arctic Ocean basin and its margins be the focus of a research program in three stages of study based on selected criteria: geologic framework and tectonic evolution, the sedimentary record and environmental history, and arctic geologic processes and environmental indicators.

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.

The structure of sedimentary basins of the Russian Arctic Seas is studied and illustrated by a number of maps, cross-sections and geophysical models. The calculated density models of the Earth crust illustrate the deep structure of the main blocks of the crust. Five major gas-condensate and gas fields are discovered here: three (Shtokman, Ludlov, Ledovoe) in the Barents and two (Leningrad and Rusanov) in the Kara Sea. Geological and geophysical characteristics of the Russian Arctic Sea sedimentary basins allow an estimation of their hydrocarbon potential by comparison with the known world analogues. Total potential resources of giant deposits of hydrocarbons in Russian Arctic Seas are estimated at 470 billion barrels of oil equivalent. The richest resources are the Kara Sea and Laptev Sea. Less rich is Barents Sea. The relatively smaller contribution to the overall estimation of the resources makes the resources of East-Siberian Sea and Chukchi Sea. Development the energy capacity of the continental shelf of Russia can play a stabilizing role in the dynamics of oil and gas production in the period 2010-2020. A key role in developing the capacity of the Arctic shelf oil and gas play is the innovative technology in exploration, production and management of the relevant investment projects. World offshore experience indicates that the combination of these factors is achieved through the formation of international firms and organizations. Comprehensively assesses the potential oil and gas resources in sedimentary basins within the Russian sector of the Arctic Ocean Describes the economic and legal challenges to the development of offshore fields in Russia Explores possible ways and timing to maKe these hydrocarbon resources available to the global market

Rifted margins mark the transition between continents and oceans, which are the two first-order types of land masses on Earth. Rifted margins contribute to our understanding of lithospheric extensional processes and are studied by various disciplines of Earth Science (geology, geophysics, geochemistry). Thanks to better and wider public access to high-quality data, our understanding in these areas has improved significantly over these last two decades. This book summarizes this knowledge evolution and details where we stand today, with a series of case examples included. It is structured in a practical way, with concise text descriptions and comprehensive diagrams. Continental Rifted Margins 2 is a useful resource for students and newcomers to the rifted margin community – a "cookbook” of sorts to facilitate the reading of scientific publications and provide basic definitions and explanations.

"To recognize the 25th anniversary of the Circum-Arctic Structural Events program, an effort organized by the Bundesanstalt für Geowissenschaften und Rohstoffe, this volume presents results from 18 major field expeditions involving 100+ geoscientists from a spectrum of disciplines. The volume focuses on the Proterozoic to Cenozoic tectonic evolution of the circum-Arctic region with correlations to adjacent orogens"--

The volume reviews current knowledge of transform margins and addresses fundamental questions for future research. Furthermore, the articles look at principal factors that influence the dynamics, kinematics and thermal regimes of continental break-up at transform margins and cover geophysics (bathymetry, seismic, gravity and magnetic studies), structural geology, sedimentology, geochemistry, plate reconstruction and thermo-mechanical numerical modelling.

This trip backward in time capsulizes in a general way the geologic development of the area that is now northern Alaska. The Cretaceous through Recent history is predominantly one of erosion of the ancient Brooks Range and filling of the Colville Geosyncline under processes like those in Operation today. All the rocks older than Jurassic, however, were deposited far from their present sites. One of the intriguing tectonic puzzles involves the geographic positions and relative timing of events that occurred during the orogeny that built the Brooks Range. I suggest that pre-Cretaceous deposition took place far to the north along the western margin of the Caledonides. Subsequently, the region that is now northern Alaska moved southward and impinged upon a northward moving plate, or plates, from the Pacific region. Interactions between these two major parts of the earth's crust produced the Brooks Range during the Jurassic. Later developments reflect continuing readjustments of the northern third of of thrust Alaska as southward movement was dissipated in diverse systems faulting and lateral displacement. ACKNOWLEDGMENTS I am indebted to many colleagues who, during the past 30 years, shared with me the excitement and pleasures of exploring the geology of northern Alaska. Among these are W. P.

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.
