Book excerpt: Large areas of grounded sea ice have been reported by early arctic explorers and more recently by the U.S. Coast Guard. The ESSA, ERTS, NOAA and DMSP satellites now provide multispectral imagery with sufficiently high resolution to allow detailed sequential observations to be made of the movement and spatial extent of arctic sea ice. This report discusses the location, formation and decay of five large (greater than 30 sq km) islands of grounded sea ice in the southern Chukchi Sea as observed for an extended period of time using satellite imagery. Measurements of the bathymetry around one grounded sea ice feature are presented along with observations made and photos taken from the ice surface. The potential use of these sea ice islands as research stations is also discussed. (Author).

This book was released on 1986 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: It may not be inapt to liken the attainment of the North Pole to the winning of a game of chess, in which all the various moves leading to a favorable conclusion had been planned in advance, long before the actual game began. It was an old game for me—a game which I had been playing for twenty-three years, with varying fortunes. Always, it is true, I had been beaten, but with every defeat came fresh knowledge of the game, its intricacies, its difficulties, its subtleties, and with every fresh attempt success came a trifle nearer; what had before appeared either impossible, or, at the best, extremely dubious, began to take on an aspect of possibility, and, at last, even of probability. Every defeat was analyzed as to its causes in all their bearings, until it became possible to believe that those causes could in future be guarded against and that, with a fair amount of good fortune, the losing game of nearly a quarter of a century could be turned into one final, complete success. It is true that with this conclusion many well informed and intelligent persons saw fit to differ. But many others shared my views and gave without stint their sympathy and their help, and now, in the end, one of my greatest unalloyed pleasures is to know that their confidence, subjected as it was to many trials, was not misplaced, that their trust, their belief in me and in the mission to which the best years of my life have been given, have been abundantly justified. But while it is true that so far as plan and method are concerned the discovery of the North Pole may fairly be likened to a game of chess, there is, of course, this obvious difference: in chess, brains are matched against brains. In the quest of the Pole it was a struggle of human brains and persistence against the blind, brute forces of the elements of primeval matter, acting often under laws and impulses almost unknown or but little understood by us, and thus many times seemingly capricious, freaky, not to be foretold with any degree of certainty. For this reason, while it was possible to plan, before the hour of sailing from New York, the principal moves of the attack upon the frozen North, it was not possible to anticipate all of the moves of the adversary. Had this been possible, my expedition of 1905-1906, which established the then "farthest north" record of 87° 6´, would have reached the Pole. But everybody familiar with the records of that expedition knows that its complete success was frustrated by one of those unforeseen moves of our great adversary—in that a season of unusually violent and continued winds disrupted the polar pack, separating me from my supporting parties, with insufficient supplies, so that, when almost within striking distance of the goal, it was necessary to turn back because of the imminent peril of starvation. When victory seemed at last almost within reach, I was blocked by a move which could not possibly have been foreseen, and which, when I encountered it, I was helpless to meet. And, as is well known, I and those with me were not only checkmated but very nearly lost our lives as well. But all that is now as a tale that is told. This time it is a different and perhaps a more inspiring story, though the records of gallant defeat are not without their inspiration. And the point which it seems fit to make in the beginning is that success crowned the efforts of years because strength came from repeated defeats, wisdom from earlier error, experience from inexperience, and determination from them all.

Download or read book On Sea Ice written by Willy Weeks and published by University of Alaska Press. This book was released on 2010-06-15 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering more than seven percent of the earth’s surface, sea ice is crucial to the functioning of the biosphere—and is a key component in our attempts to understand and combat climate change. With On Sea Ice, geophysicist W. F. Weeks delivers a natural history of sea ice, a fully comprehensive and up-to-date account of our knowledge of its creation, change, and function. The volume begins with the earliest recorded observations of sea ice, from 350 BC, but the majority of its information is drawn from the period after 1950, when detailed study of sea ice became widespread. Weeks delves into both micro-level characteristics—internal structure, component properties, and phase relations—and the macro-level nature of sea ice, such as salinity, growth, and decay. He also explains the mechanics of ice pack drift and the recently observed changes in ice extent and thickness. An unparalleled account of a natural phenomenon that will be of increasing importance as the earth’s temperature rises, On Sea Ice will unquestionably be the standard for years to come.
Download or read book An Introduction to Frozen Ground Engineering written by Orlando B. Andersland and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frozen Ground Engineering first introduces the reader to the frozen environment and the behavior of frozen soil as an engineering material. In subsequent chapters this information is used in the analysis and design of ground support systems, foundations, and embankments. These and other topics make this book suitable for use by civil engineering students in a one-semester course on frozen ground engineering at the senior or first-year-graduate level. Students are assumed to have a working knowledge of undergraduate mechanics (statics and mechanics of materials) and geotechnical engineering (usual two-course sequence). A knowledge of basic geology would be helpful but is not essential. This book will also be useful to advanced students in other disciplines and to engineers who desire an introduction to frozen ground engineering or references to selected technical publications in the field. BACKGROUND Frozen ground engineering has developed rapidly in the past several decades under the pressure of necessity. As practical problems involving frozen soils broadened in scope, the inadequacy of earlier methods for coping became increasingly apparent. The application of ground freezing to geotechnical projects throughout the world continues to grow as significant advances have been made in ground freezing technology. Freezing is a useful and versatile technique for temporary earth support, groundwater control in difficult soil or rock strata, and the formation of subsurface containment barriers suitable for use in groundwater remediation projects.

Download or read book Antarctic Palaeoenvironments and Earth Surface Processes written by M.J. Hambrey and published by Geological Society of London. This book was released on 2013-12-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume highlights developments in our understanding of the palaeogeographical, palaeobiological, palaeoclimatic and cryospheric evolution of Antarctica. It focuses on the sedimentary record from the Devonian to the Quaternary Period. It features tectonic evolution and stratigraphy, as well as processes taking place adjacent to, beneath and beyond the ice-sheet margin, including the continental shelf. The contributions in this volume include several invited review papers, as well as original research papers arising from the International Symposium on Antarctic Earth Sciences in Edinburgh, in July 2011. These papers demonstrate a remarkable diversity of Earth science interests in the Antarctic. Following international trends, there is particular emphasis on the Cenozoic Era, reflecting the increasing emphasis on the documentation and understanding of the past record of ice-sheet fluctuations. Furthermore, Antarctic Earth history is providing us with important information about potential future trends, as the impact of global warming is increasingly felt on the continent and its ocean.
