Climate change in the Arctic Ocean has stirred a remarkable surge of interest and concern. Study after study has revealed the astonishing speed of physical, chemical, ecological, and economic change throughout the expanse of the Arctic. What is more, the consequences of the changing Arctic are not restricted to the Arctic itself, but affect everyone in the Northern Hemisphere, ranging as they do from extreme weather to resource availability and food security, with implications for politics, economics, and sociology. The challenge is to comprehend the full extent and variety of these consequences, and meeting this challenge will demand a multi- and transdisciplinary understanding. Only by this means can we hope to map out a knowledge-based ecosystem and move toward knowledge-based resource management—the essential precondition for any sustainable future. In this book, leading international experts, from many felds of science and across the entire pan-Arctic region, give their specifc takes on where the Arctic Ocean is heading. All have taken care in their writing not to exclude non-experts, in the conviction that multi- and transdisciplinarity can only be achieved when communication and outreach are not tribal in nature. The recurrent guiding theme throughout these pages is “Whith -er the Arctic Ocean?” Taken in concert, the essays synthesize the current state of scientifc knowledge to project how climate change may impact on the Arctic Ocean and the continents around it. How can and how should we prepare for the imminent future that is already lapping at the threshold of the commons? What readers will hopefully take from this multi- and transdisciplinary endeavor is not the individual perspective of each contribution, but the picture that emerges across the entire suite of essays. As we move into a near future that will encompass both the probable and surprises, this book attempts to conjure the multi-dimensional space in which a sustainable future must be brought into being.

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.

This seminal book results from a NATO Advanced Research Workshop at the University of Cambridge with Russian co-directorship, enabling the first formal dialogue between NATO and Russia about security issues in the Arctic Ocean. Involving interdisciplinary participation with experts from 17 nations, including all of the Arctic states, this workshop itself reflects progress in Arctic cooperation and collaboration. Interests now are awakening globally to take advantage of extensive energy, shipping, fishing and tourism opportunities in the Arctic Ocean as it is being transformed from a permanent sea-ice cap to a seasonally ice-free sea. This environmental state-change is introducing inherent risks of political, economic and cultural instabilities that are centralized among the Arctic states and indigenous peoples with repercussions globally. Responding with urgency, environmental security is presented as an "integrated approach for assessing and responding to the risks as well as the opportunities generated by an environmental state-change." In this book – diverse perspectives on environmental security in the Arctic Ocean are shared in chapters from high-level diplomats, parliamentarians and government officials of Arctic and non-Arctic states; leaders of Arctic indigenous peoples organizations; international law advisors from Arctic states as well as the United Nations; directors of inter-governmental organizations and non-governmental organizations; managers of multi-national corporations; political scientists, historians and economists; along with Earth system scientists and oceanographers. Building on the “common arctic issues” of “sustainable development and environmental protection” established by the Arctic Council – environmental security offers an holistic approach to assess opportunities and risks as well as develop infrastructure responses with law of the sea as the key “international legal framework” to “promote the peaceful uses” of the Arctic Ocean. With vision for future generations, environmental security is a path to balance national interests and common interests in the Arctic Ocean for the lasting benefit of all.

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

The Arctic, long described as the world’s last frontier, is quickly becoming our first frontier—the front line in a world of more diffuse power, sharper geopolitical competition, and deepening interdependencies between people and nature. A space of often-bitter cold, the Arctic is the fastest-warming place on earth. It is humanity’s canary in the coal mine—an early warning sign of the world’s climate crisis. The Arctic “regime” has pioneered many innovative means of governance among often-contentious state and non-state actors. Instead of being the “last white dot on the map,” the Arctic is where the contours of our rapidly evolving world may first be glimpsed. In this book, scholars and practitioners—from Anchorage to Moscow, from Nuuk to Hong Kong—explore the huge political, legal, social, economic, geostrategic and environmental challenges confronting the Arctic regime, and what this means for the future of world order.

Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

Who actually controls the Northwest Passage? Who owns the trillions of dollars of oil and gas beneath the Arctic Ocean? Which territorial claims will prevail, and why — those of the United States, Russia, Canada, or the Nordic nations? And, in an age of rapid climate change, how do we protect the fragile Arctic environment while seizing the economic opportunities presented by the rapidly melting sea-ice? Michael Byers, a leading Arctic expert and international lawyer clearly and concisely explains the sometimes contradictory rules governing the division and protection of the Arctic and the disputes over the region that still need to be resolved. What emerges is a vision for the Arctic in which cooperation, not conflict, prevails and where the sovereignty of individual nations is exercised for the benefit of all. This insightful little book is an informed primer for today's most pressing territorial issue.
