Book Description
Seismology in polar regions (Arctic and Antarctic) allows us to study the static condition and high-latitude dynamics of the Earth. This book covers the recent developments in seismology in polar regions; observations and networks; international collaboration; heterogeneous structure and dynamics of the lithosphere; deep Earth's interiors observed from high latitudes; characteristics of seismicity and seismic wave propagation; and global tectonics in terms of Earth's history, including the interdisciplinary studies on the interaction between Earth's spheres. Since the International Polar Year (IPY) in 2007/2008 was the most exciting campaign launched within contemporary polar studies, this book observes recent seismological achievements by the IPY, specifically focusing on the seismic signals near the surface associated with cryosphere dynamics and evolution. Topics on cryoseismology, such as glacial earthquake activities, are viewed in terms of global warming. Moreover, observational experiments and long-term monitoring under the extreme conditions in the polar environment are also discussed.

Book Description
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.

Book Description
Geological correlations of East Antarctica with adjoining continents have been puzzling geologists ever since the concept of a Gondwana supercontinent surfaced. Despite the paucity of outcrops because of ice cover, difficulty of access and extreme weather, the past 50 years of Japanese Antarctic Research Expeditions (JARE) has successfully revealed vital elements of the geology of East Antarctica. This volume presents reviews and new research from localities across East Antarctica, especially from Dronning Maud Land to Enderby Land, where the geological record preserves a history that spans the Archaean and Proterozoic. The reviews include extensive bibliographies of results obtained by geologists who participated in the JARE. Comprehensive geological, petrological and geochemical studies, form a platform for future research on the formation and dispersion of Rodinia in the Mesoproterozoic and subsequent assembly of Gondwana in the Neoproterozoic to Early Palaeozoic.

Book Description
This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems. Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change. This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota. Polar Lakes and Rivers will be of value to students and specialist researchers alike, as well as to those with a more general interest in aquatic ecology, polar environments or global change who require an authoritative overview of this fast emerging topic.

Book Description
Fourteen chapters discuss regional stratigraphy by time intervals from Precambrian to Quaternary, while other chapters describe the geography, geomorphology, tectonics, geophysical characteristics, and resources of the region. A summary chapter includes geologic maps, structural cross-sections, a geotectonic correlation chart, a gravity map, and a location map for exploration wells in the Arctic Islands and northern Greenland. A wealth of additional information is contained on the nine accompanying plates.

Book Description
This book is devoted to different aspects of tectonic researches. New results and interpretations are presented here for diverse tectonic settings. Most of the chapters include up-to-date materials of detailed geological investigations, often combined with geophysical data, which can help understand more clearly the essence of mechanisms of different tectonic processes. Some chapters are devoted to the tectonic evolution of regions (East Antarctica, East Kazakhstan, Mongolo-Okhotsk orogenic belt), and others have dealt with the different aspects of tectonic events: influence of detachment structural deformation on pore structure evolution in shales, evolution of drainage in response to brittle-ductile dynamics and surface processes, soft sediment deformation structures triggered by the modern earthquakes, and post-opening deformation history of the Japan Sea back-arc basin.

Book Description
Edgar Cayce, America's best documented psychic, gave upwards of 44 readings that dealt with lost continents, geophysical changes to Earth beginning 1958-1998, and a pole shift due to begin about now. In this book, geologist William Hutton and researcher Jonathan Eagle look for correspondences between results of geophysical research studies and psychic descriptions of prehistoric catastrophes. They also seek scientifically to test readings' predictions of catastrophic Earth changes, all the while investigating the following fascinating subjects: * Development and calibration of a comprehensive pole-shift model * The countries predicted to be most affected by a sudden, 1° pole shift. * The geologic trend for a mineralized gold vein at Bimini, Bahamas. * The authors' discoveries of correlations between: - a 2002 arctic earthquake and the eruption of torrid-area volcanoes, - the dropping of atom bombs in 1945 and a significant increase in sunspots following, and - the peaceable nature of Europe in 1645-1715 and the period's near total lack of sunspots. (Cayce readings implied or predicted all three phenomena.) * The first-ever analysis of the sources of Cayce's channeled readings, including a ranking of the veracity and reliability of the most important Earth changes and pole-shift readings. * Moralistic reasons for future catastrophic geophysical changes to Japan, China, and America. * Locations of post-pole-shift safety lands in Canada and America. * Locations of the records of the Atlantean civilization, to be found when Earth changes begin. * How to awaken to the New Cycle presently opening before humanity. * Evidence for Atlantis in the mid-Atlantic ridge area and for Lemuria (or Mu) in the Pacific. * The consuming religious war in which we find ourselves, and an answer to world conditions today. * Visions of an imminent Age-ending fire, as found in a Cayce reading, in a channeled book by Phylos the Tibetan, and in the 1960s visions of girls at Garabandal, Spain. * Doubtful interpretations of Earth-changes and pole-shift readings advanced by managers and writers of Cayce's legacy organization, the Association for Research and Enlightenment, Inc. From the Foreword by the Editor: "The acid test of pole shift and other Earth change predictions is their scientific credibility. If true, momentous societal and political changes are imminent. The geopolitical map of the world will be redrawn. The authors are exploring the transition from the end of one Age to the beginning of another."
