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: 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 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.

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.

Download or read book Mid Term Assessment of Progress on the 2015 Strategic Vision for Antarctic and Southern Ocean Research written by National Academies Of Sciences Engineeri and published by National Academies Press. This book was released on 2022-07-28 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic's unique environment and position on the globe make it a prime location to gain insights into how Earth and the universe operate. This report assesses National Science Foundation (NSF) progress in addressing three priority research areas identified in a 2015 National Academies report: (1) understanding the linkages between ice sheets and sea-level rise, including both a focus on current rates of ice sheet change and studies of past major ice sheet retreat episodes; (2) understanding biological adaptations to the extreme and changing Antarctic environment; and (3) establishing a next-generation cosmic microwave background (CMB) program, partly located in Antarctica, to study the origins of the universe. NSF has made important progress understanding the impacts of current ice sheet change, particularly through studies focused on the ice sheet and ocean interactions driving ongoing ice mass loss at the Thwaites Glacier and Amundsen Sea region in West Antarctica. Less progress has been made on studies of past major ice sheet retreat episodes. Progress is also strong on CMB research to understand the origins of the universe. Progress has lagged on understanding biological adaptations, in part because of limited community organization and collaboration toward the priority. To accelerate progress during the second half of the initiative, NSF could issue specific calls for proposals, develop strategies to foster collaborations and partnerships, and commission a transparent review of logistical capacity to help illuminate strategies and priorities for addressing resource constraints. Such efforts would also help optimize science and proposal development in an environment of inherently constrained logistics.
