Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 53. The Cold Deserts of Antarctica and the Polar Deserts of the High Arctic, the latter of which includes the Queen Elizabeth Islands, northern Greenland, Svalbard, Franz Josef Land, Severnaya Zemlya, and a few other localities, have cryogenic soils with desertlike features. Both sectors have soils with a mineral appearance, desert pavement, small to nonexistent organic components, and low ground temperatures. Both are underlain by permafrost and are subject to cryogenic processes. Whereas virtually all of the soils in Antarctica are well drained, in the High Arctic the soil pattern consists of a mosaic of Polar Desert soils, as well as various hydric varieties including shallow bogs. In the Polar Deserts the landforms, especially the surficial deposits, are much younger chronologically than their Cold Desert counterparts. Polar Desert soils generally have a more acid reaction than Cold Desert soils. Moisture regimes are quite different in the two sectors. Cold Desert soils have a dry condition even down to the frost table. Polar Desert soils are moist during early summer thaw, however, and are subjected to occasional summer rainfall and probably receive some moisture from condensation; the zone above the receding frost table is usually quite wet. The humus component in Cold Desert soils is usually nil, but in the Polar Desert soils it is commonly as much as 1% to 2% or higher, especially in medium?]textured soils. Whether there are enough distinct differences between the two soils to recognize two different categories remains somewhat moot. After equating all information, however, one appears to be justified in tentatively recognizing two distinct soils.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 67. A high amplitude magnetic anomaly occurs over the Butcher Ridge igneous complex in the Transantarctic Mountains. This sill-like body is approximately 10 km long where exposed. It ranges from basalt to rhyolite in composition and has been suggested as evidence of a large mafic intrusion at depth. A single NW-SE aeromagnetic profile flown across Butcher Ridge gave an 8-km-wide positive anomaly with maxima of about 700 and 1000 nT which are associated with topographic peaks that the aircraft cleared at about 300 and 600 m respectively. The observed amplitude of the Butcher Ridge anomaly is too great to be caused by a typical sill of Ferrar Dolerite, examples of which are widely exposed along the Transantarctic Mountains. Models that fit the observed data indicate magnetizations comparable to the Jurassic Dufek layered mafic intrusion in the Transantarctic Mountains near the Weddell Sea. Model calculations show that the upper, and most magnetic part of the inferred intrusion must be greater than about 2 km thick and that the entire intrusion is probably substantially thicker. We interpret the source of the Butcher Ridge magnetic anomaly to be a layered mafic intrusion, syntectonic with the Jurassic Transantarctic (failed) rift, marked by the Ferrar Dolerite. The magnetic evidence for a buried mafic body beneath the Butcher Ridge igneous complex is the first evidence of possible Jurassic cumulate rocks in the Transantarctic Mountains bordering the Ross Embayment-Byrd Subglacial Basin.

Book excerpt: India launched its maiden scientific expedition to Antarctica way back in 1981 and ever since annual expeditions are launched to address thematic research in the contemporary areas of Antarctic Science and Engineering. The initial efforts and achievements of India are not only significant but are of historical importance. This book discusses a wide array of topics that have entered the mainstream of geotechnical and geo environmental engineering over the initial two and half decades of India’s presence in the icy continent ‘Antarctica’. At the same time, it highlights the lessons learnt in cryo-engineering technologies. It covers various articles on many aspects of environmental science and collates the overall achievements in the fascinating field of Antarctic engineering and environmental impact assessment. Accordingly, this book covers articles on wind energy by Ramesh et al., and engineering aspects in Antarctica by Rai. Similarly, Pathak has reviewed the engineering details of Dakshin Gangotri and Maitri. On the contrary, Sharma has provided an interesting history about the process of establishment of Dakshin Gangotri station. Similarly, communication aspects have been highlighted by Dhaka. Commercial polymers and their utility in cold region have been discussed by Dabholker et al. Besides, Tiwari and Khare have reviewed the environmental studies carried out during the initial 25 years in Antarctic research base ‘Maitri’. Similarly, Ramchandran and Sathe have studied the natural radioactivity in Antarctica while fire safety in Antarctica has been touched upon by Chatterjee. On the other hand, Veerbhadraiah and Jain have provided a status on environmental management services at Maitri station Additionally Tiwari has provided details on the new Indian Research Base ‘Bharti’ at Larsemann Hills region. It provides a one-stop reference for researchers and those working in industry and government.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 24. The Antarctic Research Series is a medium for authoritative reports on the extensive scientific research being done in Antarctica. The series has elicited contributions from leading scientists; it seeks to maintain high scientific and publication standards. The scientific editor for each volume is chosen from among recognized authorities in the discipline or theme that it represents, as are the reviewers on whom the editor relies for advice. Research results appearing in this series are original contributions too long or otherwise inappropriate for publication in standard journals. The material is directed to specialists actively engaged in the work, to graduate students, to scientists in closely related fields, and to laymen versed in the environmental sciences. Some volumes comprise a single monograph. Others are collections of papers with a common theme.

Book excerpt: In "Two Years Below the Horn," engineer Andrew Taylor vividly recounts his experiences and accomplishments during Operation Tabarin, a landmark British expedition to Antarctica to establish sovereignty and conduct science during the Second World War. When mental strain led the operation's first commander to resign, Taylor--a military engineer with extensive prewar surveying experience--became the first and only Canadian to lead an Antarctic expedition. As commander of the operation, Taylor oversaw construction of the first permanent base on the Antarctic continent at Hope Bay. From there, he led four-man teams on two epic sledging journeys around James Ross Island, overcoming arduous conditions and correcting cartographic mistakes made by previous explorers. The editors' detailed afterword draws on Taylor's extensive personal papers to highlight Taylor's achievements and document his significant contributions to polar science. This book will appeal to readers interested in the history of polar exploration, science, and sovereignty. It also sheds light on the little known contribution of a Canadian to a distant theatre of the Second World War. The wartime service of Major Taylor reveals important new details about a groundbreaking operation that laid the foundation for the British Antarctic Survey and marked a critical moment in the transition from the heroic to the modern scientific era in polar exploration.
Download or read book Enhancing NASA s Contributions to Polar Science written by National Research Council and published by National Academies Press. This book was released on 2001-04-23 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high latitudes of the Arctic and Antarctic, together with some mountainous areas with glaciers and long-lasting snow, are sometimes called the cryosphere-defined as that portion of the planet where water is perennially or seasonally frozen as sea ice, snow cover, permafrost, ice sheets, and glaciers. Variations in the extent and characteristics of surface ice and snow in the high latitudes are of fundamental importance to global climate because of the amount of the sun's radiation that is reflected from these often white surfaces. Thus, the cryosphere is an important frontier for scientists seeking to understand past climate events, current weather, and climate variability. Obtaining the data necessary for such research requires the capability to observe and measure a variety of characteristics and processes exhibited by major ice sheets and large-scale patterns of snow and sea ice extent, and much of these data are gathered using satellites. As part of its efforts to better support the researchers studying the cryosphere and climate, the National Aeronautics and Space Administration (NASA)-using sophisticated satellite technology-measures a range of variables from atmospheric temperature, cloud properties, and aerosol concentration to ice sheet elevation, snow cover on land, and ocean salinity. These raw data are compiled and processed into products, or data sets, useful to scientists. These so-called "polar geophysical data sets" can then be studied and interpreted to answer questions related to atmosphere and climate, ice sheets, terrestrial systems, sea ice, ocean processes, and many other phenomena in the cryosphere. The goal of this report is to provide a brief review of the strategy, scope, and quality of existing polar geophysical data sets and help NASA find ways to make these products and future polar data sets more useful to researchers, especially those working on the global change questions that lie at the heart of NASA's Earth Science Enterprise.

Book excerpt: Jackie Ronne reclaims her rightful place in polar history as the first American woman in Antarctica. Jackie was an ordinary American woman whose life changed after a blind date with rugged Antarctic explorer Finn Ronne. After marrying, they began planning the 1946–1948 Ronne Antarctic Research Expedition. Her participation was not welcomed by the expedition team of red-blooded males eager to prove themselves in the frozen, hostile environment of Antarctica. On March 12, 1947, Jackie Ronne became the first American woman in Antarctica and, months later, one of the first women to overwinter there. The Ronne Antarctic Research Expedition secured its place in Antarctic history, but its scientific contributions have been overshadowed by conflicts and the dangerous accidents that occurred. Jackie dedicated her life to Antarctica: she promoted the achievements of the expedition and was a pioneer in polar tourism and an early supporter of the Antarctic Treaty. In doing so, she helped shape the narrative of twentieth-century Antarctic exploration.
