Marine Geological And Geophysical Atlas Of The Circum Antarctic To 300s

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 54. This atlas and explanatory text were compiled under the sponsorship of the Division of Polar Programs (DPP) of the National Science Foundation (NSF). Relatively little interpretation has been incorporated into the synthesis beyond that implicit in the publications used, that inherent in the various analyses procedures required, or that required to reconcile apparently discrepant data or interpretations. This series of maps does, however, represent considerably more than a compilation of published results. The maps also incorporate extensive new and unpublished geological and geophysical data as well as many invaluable data that have appeared previously only in the gray literature (e.g., national and international agency and institutional technical reports).

A comprehensive single-authored book to introduce students and researchers to the marine geology of the Antarctic.

New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.

The present book covers diversified contributions addressing the impact of climate change on the Antarctic environment. It covers the reconstruction of environmental changes using different proxies. The chapters focus on the glacial history, glacial geomorphology, sedimentology, and geochemistry of Antarctic region. Furthermore, the Cenozoic evolution of the Antarctic ice sheet is discussed along with a Scientometrics analysis of climate change research. The book serves as a useful reference for researchers who are fascinated by the polar region and environmental research.
