Book Description
Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 57. Lakes of the dry valley region near McMurdo Sound, Antarctica, which are perennially ice-covered (approximately 4 m thick) and contain only microorganisms in the plankton, present unique systems for studies in hydrologic optics. Profiles of the flux and spectral distribution of photosynthetically available radiation (400-700 nm) and the optical properties of suspended particulate material were measured for Lake Bonney and Lake Fryxell.

Book Description
Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 50. The Antarctic Research Series, an outgrowth of research done in the Antarctic during the International Geophysical Year, was begun in 1963 with a grant from the National Science Foundation to the American Geophysical Union. It is a book series designed to serve scientists, including graduate students, actively engaged in Antarctic or closely related research, and others versed in the biological or physical sciences. It provides a continuing, authoritative medium for the presentation of extensive and detailed scientific research results from Antarctica, particularly the results of the United States Antarctic Research Program.

Book Description
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 Description
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.

Book Description
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.

Book Description
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.

Book Description
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.
