The Transantarctic Mountains


Book Description

This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.




The Ross Orogen of the Transantarctic Mountains


Book Description

The Ross Orogen of the Transantarctic Mountains is the part of the orogenic system that formed at the Pacific continental margin of present-day Antarctica. According to a recent hypothesis, this continental margin was created by the rifting and subsequent drift of Laurentia from Gondwana. With an unparalleled breadth and depth of information, this book provides a detailed synthesis of the history of the Ross orogen. In doing so, it incorporates classical studies with discussions of the most recent and controversial research from the international community. The book also includes a comprehensive bibliography and a historical chronology of all expeditions that have worked on the Ross orogen in the Transantarctic Mountains, from the first sightings by Ross in 1840 right up to the present day. This review of the Ross orogen of the Transantarctic Mountains will be valuable to all geologists interested in these episodes in the Earth's history, and to researchers of the geology of Antarctica.




Volcanism in Antarctica: 200 Million Years of Subduction, Rifting and Continental Break-up


Book Description

This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).




Frozen in Time


Book Description

No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.




The Soils of Antarctica


Book Description

This book divides Antarctica into eight ice-free regions and provides information on the soils of each region. Soils have been studied in Antarctica for nearly 100 years. Although only 0.35% (45,000 km2) of Antarctica is ice-free, its weathered, unconsolidated material qualify as “soils”. Soils of Antarctica is richly illustrated with nearly 150 images and provisional maps are provided for several key ice-free areas.




Mountaineering in Antarctica


Book Description

CLIMBING & MOUNTAINEERING. Mountaineering in Antarctica is a comprehensive overview of climbing history and expeditions by a recognized expert on the territory. Damien Gildea's research encompasses journeys from the Heroic Age of Antarctic exploration, through the expansion of international scientific activity in the latter half of the 20th century, to the modern adventure tourism of the new millennium. This book is a tribute to the mountains themselves and to the experiences of those who have traveled among them their triumphs, travails, and tragedies. For the first time, the peaks and ranges of the planet's wildest continent are revealed in one place for all to see.




Blazing Ice


Book Description

The Antarctic is the last vast terrestrial frontier. Just over a century ago, no one had ever seen the South Pole. Today odd machines and adventure skiers from many nations converge there every summer, arriving from numerous starting points on the Antarctic coast and returning some other way. But not until very recently has anyone completed a roundtrip from McMurdo Station, the U.S. support hub on the continental coast. The last man to try that perished in 1912. The valuable surface route from McMurdo remained elusive until John H. Wright and his crew finished the job in 2006. Blazing Ice is the story of the team of Americans who forged a thousand-mile transcontinental ôhaul routeö across Antarctica. For decades airplanes from McMurdo Station supplied the South Pole. A safe and repeatable surface haul route would have been cheaper and more environmentally benign than airlift, but the technology was not available until 2000. As Wright reveals in this gripping narrative, the hazards of Antarctic terrain and weather were as daunting for twenty-firstcentury pioneers as they were for NorwayÆs Roald Amundsen and EnglandÆs Robert Falcon Scott when they raced to be first to the South Pole in 1911û1912. Wright and his team faced deadly hidden crevasses, vast snow swamps, the Transantarctic Mountains, badlands of weird windsculpted ice, and the high Polar Plateau. Blazing Ice will appeal to Antarctic aficionados, conservationists, and adventure readers of all stripes.




The Vegetation of Antarctica through Geological Time


Book Description

The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the paleoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic paleobotany and terrestrial paleoecology.
