Book Description
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.

Book Description
"As soon as humans spied and later set foot on the remote Antarctic continent in the early nineteenth century, they became aware of its ice cover, and desired to learn about its extent, shape, thickness, and behavior. In this book, David Drewry-glaciologist and former Director of the Scott Polar Research Institute-recounts the science and history of a ground-breaking time in recent Antarctic geophysical exploration, in which scientists were finally able to "see" through the Antarctic ice sheet and take its measure. From the mid-1960s to the mid-1980s, scientists' ability to peer beneath the Antarctic ice sheet and map its thickness was revolutionized by the technology, techniques, and exploratory campaigns of the Radio Echo Sounding Programme, conducted by the Scott Polar Research Institute at Cambridge in the UK. The exploratory radar mapping campaigns of this ambitious research program were largely accomplished during the Cold War, as interest and concern in global climate change were just emerging. To those involved in this research and fieldwork, it was evident that the environment of the planet was indeed changing, and that the great ice masses of Antarctica and Greenland, and their evolving stability and behavior, would feature significantly in understanding the future of our world. This book gives an account of the Radio Echo Sounding Programme, describing the scientific background, goals, various scientific, human, political, and natural challenges, and discoveries of the research program. It follows the twists and turns of operating in a remote and hostile region, where detailed and exact planning and preparations were constantly at risk of disruption by bad weather, mechanical and electronic breakdowns, aircraft crashes, and human frailty. It also highlights the strong international cooperation that occurred in Antarctica, during this contentious time in history, speaking to the importance of the 1961 Antarctic Treaty as well as the necessity of working together to tackle problems of global significance"--

Book Description
A gripping history of the polar continent, from the great discoveries of the nineteenth century to modern scientific breakthroughs Antarctica, the ice kingdom hosting the South Pole, looms large in the human imagination. The secrets of this vast frozen desert have long tempted explorers, but its brutal climate and glacial shores notoriously resist human intrusion. Land of Wondrous Cold tells a gripping story of the pioneering nineteenth-century voyages, when British, French, and American commanders raced to penetrate Antarctica’s glacial rim for unknown lands beyond. These intrepid Victorian explorers—James Ross, Dumont D’Urville, and Charles Wilkes—laid the foundation for our current understanding of Terra Australis Incognita. Today, the white continent poses new challenges, as scientists race to uncover Earth’s climate history, which is recorded in the south polar ice and ocean floor, and to monitor the increasing instability of the Antarctic ice cap, which threatens to inundate coastal cities worldwide. Interweaving the breakthrough research of the modern Ocean Drilling Program with the dramatic discovery tales of its Victorian forerunners, Gillen D’Arcy Wood describes Antarctica’s role in a planetary drama of plate tectonics, climate change, and species evolution stretching back more than thirty million years. An original, multifaceted portrait of the polar continent emerges, illuminating our profound connection to Antarctica in its past, present, and future incarnations. A deep-time history of monumental scale, Land of Wondrous Cold brings the remotest of worlds within close reach—an Antarctica vital to both planetary history and human fortunes.

Book Description
Antarctica consists of a continental-type land mass covered by a thick mantle of snow-formed ice. The land surface beneath the ice is below sea level in many places, but since troughs and basins are solidly filled with permanent ice, the rock depression is partly due to imposed ice load, and the earth's crust is of continental type, Antarctica can be regarded as a continent having some major basal troughs. The surfaceAREA OF THE CONTINENT AND ITS FRINGING ICE SHELVES IS ABOUT 5,500,000 SQUARE MILES. (Author).

Book Description
Scientific and mythological evidence that Antarctica was once Atlantis • Reveals how the earth’s crust shifted in 9600 BCE, dragging Atlantis into the polar zone beneath miles of Antarctic ice • Examines ancient yet highly accurate maps, including the Piri Reis map of 1513, which reveals a pre-glacial Antarctica • Shows how myths of floods and disaster from around the world all point to a common source In this completely revised and expanded edition of When the Sky Fell, Rand and Rose Flem-Ath show that 12,000 years ago vast areas of Antarctica were free from ice and home to the kingdom of Atlantis, a proposition that also elegantly solves the mysteries of ice ages and mass extinctions, the simultaneous worldwide rise of agriculture, and the source of devastating prehistoric climate change. Expanding upon Charles Hapgood’s theory of earth crust displacement, which was championed by Albert Einstein, they examine ancient yet highly accurate world maps, including the Piri Reis map of 1513, and show how the earth’s crust shifted in 9600 BCE, dragging Atlantis into the polar zone where it now lies beneath miles of Antarctic ice. From the Cherokee, Haida, and Okanagan of North America to the earliest records of Egypt, Iran, Mexico, and Japan, they reveal that ancient myths of floods, lost island paradises, and visits from advanced godlike peoples from all corners of the globe all point to the same worldwide catastrophe that resulted in Atlantis’s demise. The authors explain how the remaining Atlanteans, amid massive earthquakes and epic floods, evacuated and spread throughout the world, resulting in the birth of the first known civilizations. Including rare material from the archives of Charles Hapgood, Albert Einstein, and Dwight D. Eisenhower, the Flem-Aths explain how an earth crust displacement could happen again in the future, perhaps in correspondence with high solar activity. With new scientific, genetic, and linguistic evidence in support of Antarctica as the location of long-lost Atlantis, this updated edition convincingly shows that Atlantis was not swallowed by the sea but was entombed beneath miles of polar ice.

Book Description
Our appreciation of glaciological processes in Antarctica suffers from a lack of observations in regions where numerical models indicate the ice sheet to be susceptible to ocean and/or atmospheric warming. The solution lies in the use and development of glacier geophysics. In this volume we present a series of papers that demonstrate how geophysics can be deployed in Antarctica to comprehend: (1) boundary conditions that influence ice flow such as subglacial topography, the distribution of basal water and ice-sheet rheology; (2) phenomena that might affect ice-flow processes, such as complex internal ice-sheet structures and the proposition of large stores of hitherto unappreciated groundwater; and (3) how glacigenic sediments and formerly glaciated terrain on, and surrounding, the continent can inform us about past ice-sheet dynamics. The volume also takes a historical view on developments leading to current knowledge, examines active ice-sheet processes, and points the way forward on how geophysics can advance quantitative understanding of Antarctic ice-sheet behaviour.

Book Description
With stunning original photographs, an Antarctic scientist and explorer takes us to one of the most sublime, remote, and pristine regions on the planet. The interior of Antarctica is an utterly pristine wilderness, a desolate landscape of ice, wind, and rock; a landscape so unfamiliar as to seem of another world. This place has been known to only a handful of early explorers and the few scientists fortunate enough to have worked there. Edmund Stump is one of the lucky few. Having climbed, photographed, and studied more of the continent-spanning Transantarctic Mountains than any other person on Earth, this geologist, writer, and photographer is uniquely suited to share these alien sights. With stories of Stump’s forty years of journeys and science, Otherworldly Antarctica contains 130 original color photographs, complemented by watercolors and sketches by artist Marlene Hill Donnelly. Over three chapters—on the ice, the rock, and the wind—we meet snowy paths first followed during Antarctica’s Heroic Age, climb the central spire of the Organ Pipe Peaks, peer into the crater of the volcanic Mount Erebus, and traverse Liv Glacier on snowmobile, while avoiding fatal falls into the blue interiors of hidden crevasses. Along the way, we see the beauty of granite, marble, and ice-cored moraines, meltwater ponds, lenticular clouds, icebergs, and glaciers. Many of Stump’s breathtaking images are aerial shots taken from the planes and helicopters that brought him to the interior. More were shot from vantages gained by climbing the mountains he studied. Some were taken from the summits of peaks. Many are of places no one had set foot before—or has since. All seem both permanent and precarious, connecting this otherworld to our fragile own.
