Papers from a conference on ice in the Arctic Ocean, including ice and wave dynamics, ice modelling, environmental aspects, vessels in ice, offshore structures in ice, ship operations, remote sensing, ice forecasting and ice acoustics. Papers deal with ice in the Arctic Ocean, shipping along the north coast of Siberta and the operation in ice of the ice-breaker Polar Sea.
"This book treats not only Wilkins's Nautilus expedition of 1931 but the diesel- and battery-powered submarine operations of the l94Os and l95Os as well as the era of nuclear-powered boats. It shows how rapid advances in science and technology helped overcome so many obstacles that today the Arctic Ocean is considered the submariner's private sea." "Author Marion Williams, a member of the U.S. Navy's submarine service for many years, tells the story from the viewpoint of the submariners themselves. To do so, he consulted countless official and unofficial documents and recently declassified reports, interviewed participants, and drew on his own professional knowledge. He provides dramatic details of every operation and also describes the military and political ramifications of each cruise. The narrative is certain to appeal to readers of all ages who enjoy tales of exploration and discovery. Dozens of photographs, many never before published, help bring the story to life."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved
The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.
Ice in the Ocean examines sea ice and icebergs and their role in the global climate system. It is comprehensive textbook suitable for students, pure and applied researchers, and anyone interested in the polar regions, the oceans, and climate. The author examines the distribution of sea ice, its mechanisms of growth, development and decay, the thermodynamics and dynamics of sea ice, sea ice deformation and ridge-building, the role of marginal ice zones, the characteristics of icebergs, and the part played by sea ice in the climate system and in the transport of pollutants. An extensive reference list, recommendations for further reading and numerous illustrations add to the value of the text.
Moving Loads on Ice Plates is a unique study into the effect of vehicles and aircraft travelling across floating ice sheets. It synthesizes in a single volume, with a coherent theme and nomenclature, the diverse literature on the topic, hitherto available only as research journal articles. Chapters on the nature of fresh water ice and sea ice, and on applied continuum mechanics are included, as is a chapter on the subject's venerable history in related areas of engineering and science. The most recent theories and data are discussed in great depth, demonstrating the advanced state of the modelling and experimental field programmes that have taken place. Finally, results are interpreted in the context of engineering questions faced by agencies operating in the polar and subpolar regions. Although the book necessarily contains some graduate level applied mathematics, it is written to allow engineers, physicists and mathematicians to extract the information they need without becoming preoccupied with details. Structural, environmental, civil, and offshore engineers, and groups who support these industries, particularly within the Arctic and Antarctic, will find the book timely and relevant.
With the fundamental changes which occurred in the political structure of Europe, and improved East--West relations in general, the Arctic has increasingly become the focal point of international attention during the last few years. Scientific research and environmental protection are areas which have already witnessed some form of international cooperation in the area. With this particular evolution in mind, a new look at the legal regime of navigation in the Arctic seems to be justified. While several other countries border on the Arctic, Canada and Russia have the most extensive shorelines and have shown keen interest in ensuring that their proper share of this area is not encroached by other countries. This book is thus generally restricted to an examination of the maritime boundaries that these states are claiming, and the extent to which other states have recognized them. It also explores the need for greater international cooperation in this area, not only between the two main contenders but also with other countries that have shown a special interest in Arctic navigation and in the exploitation of resources of this area.
Sea Ice: Physics and Remote Sensing addresses experiences acquired mainly in Canada by researchers in the fields of ice physics and growth history in relation to its polycrystalline structure as well as ice parameters retrieval from remote sensing observations. The volume describes processes operating at the macro- and microscale (e.g., brine entrapment in sea ice, crystallographic texture of ice types, brine drainage mechanisms, etc.). The information is supported by high-quality photographs of ice thin-sections prepared from cores of different ice types, all obtained by leading experts during field experiments in the 1970s through the 1990s, using photographic cameras and scanning microscopy. In addition, this volume presents techniques to retrieve a suite of sea ice parameters (e.g. ice type, concentration, extent, thickness, surface temperature, surface deformation, etc.) from space-borne and airborne sensor data. The breadth of the material on this subject is designed to appeal to researchers and users of remote sensing data who want to develop quick familiarity with the capabilities of this technology or detailed knowledge about major techniques for retrieval of key ice parameters. Volume highlights include: Detailed crystallographic classification of natural sea ice, the key information from which information about ice growth conditions can be inferred. Many examples are presented with material to support qualitative and quantitative interpretation of the data. Methods developed for revealing microstructural characteristics of sea ice and performing forensic investigations. Data sets on radiative properties and satellite observations of sea ice, its snow cover, and surrounding open water. Methods of retrieval of ice surface features and geophysical parameters from remote sensing observations with a focus on critical issues such as the suitability of different sensors for different tasks and data synergism. Sea Ice: Physics and Remote Sensing is intended for a variety of sea ice audiences interested in different aspects of ice related to physics, geophysics, remote sensing, operational monitoring, mechanics, and cryospheric sciences.
