This book was released on 2004 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine geological evidence supports rapid retreat of the West Antarctic Ice Sheet in the eastern Ross Sea before the last glacial maximum. As the only accessible marine record of a major drainage outlet of the West Antarctic Ice Sheet (WAIS), this central and eastern Ross Sea dataset provides a unique opportunity to test the hypothesis of WAIS instability, assess its regulating role in eustasy, and explore the geological record of paleo-ice stream behavior. As the last vast marine-based ice sheet on the planet, the WAIS is seen as a key source of potentially rapid sea level rise. The collapse and disintegration of the WAIS would raise sea level by 5 to 6 meters, a major threat to the world's coastal cities. Marine geological data were collected along the axis of large bathymetric troughs during a 1999 cruise of the R/V Nathanial B. Palmer. Thick till sheets, extensive lineations, and multiple grounding zone wedges imaged on seismic profiles and multibeam bathymetric records, indicate that troughs in the Ross Sea were occupied by paleo-ice streams during the last glacial maximum. Ice stream boundaries in the eastern Ross Sea are characterized by laterally accreting sedimentary strata indicating lateral migration of ice streams. The abrupt transition from lineated to non-lineated morphologies reflects sharp ice stream margins. Sediment cores recovered glacial-marine deposits overlying till, a facies succession that indicates an abrupt transition from subglacial to open marine deposition. High concentrations of ice rafted debris in the glacial-marine units and iceberg furrows suggest mass wasting of the ice sheet and iceberg calving from the grounding line during retreat. Corrected radiocarbon ages of samples taken above the contact between subglacial (till) and glacial-marine sediments range from 23.4 to 26.0 ka. B.P., indicating pre-LGM ice sheet withdrawal in the eastern Ross Sea. This was long before the ice sheet retreated from the western Ross Sea and is inconsistent with previous models for ice sheet retreat in the region.

Download or read book The Geology of Antarctica written by Robert J. Tingey and published by Oxford University Press, USA. This book was released on 1991 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological information from Antarctica has so far been published in expedition reports, conference proceedings, and science journals. This information is thus not readily accessible to Earth scientists who are interested, but not directly involved, in Antarctic research. The Geology ofAntarctica bridges this gap with each chapter presenting an authoritative review of a particular aspect of Antarctic geology. The text provides descriptions of all major rock units found in Antarctica, as well as reviews of Antarctic palaeontology, geophysics, petroleum prospects, and mineral resources. Special attention is drawn to the features of Antarctica that are significant from the wider perspectives of globalgeology.

Book excerpt: This is the first book solely devoted to Cryopedology, the study of soils of cold regions. The analysis treats Cryosols as a three-part system (active layer, transition layer, permafrost). The book considers soil-forming factors, cryogenic processes, and classification and distribution of Cryosols. Cryosols of the Arctic, Antarctica, and the high mountains are considered in detail. The chapters address cryosols and earth-system science, cryosols in a changing climate, cryosols databases and their use, and management of cryosols. The book is rich in color photographs and highlights the author’s 43 field trips to Antarctica, the Arctic, and alpine areas.

Book excerpt: The study of Antarctic communities can provide a valuable step forward in investigating the control of community development, the utilization of habitats and the interaction among species in both species rich and species poor communities. This book contains chapters characterizing the present approaches to both aquatic and terrestrial communities in the Antarctic. From biodiversity to trophic flows, from ecophysiological strategies to the impacts of environmental change and the effects of human disturbance, this volume provides an up to the minute overview of community studies in an area covering ten percent of the Earth's surface.
