Book Description
The geoscientific results of the Victoria Land Traverse, 1959-60 are presented with interpretations and conclusions. The major geographical discoveries, the Arctic Institute Range and the Rennick Glacier, are treated and descriptions and locations given. The presence of a vast ice thickness, which in many cases exceeds 2.0 km. is reported covering Victoria Land and is shown to conceal a major subglacial depression. Subglacial rock topography influences the relief of the ice surface of Victoria Land as seen upon comparison of seismic and altimetric results. The presence of prolonged seismic surface noise is reported and attributed to low temperature phenomena. (Author).

Book Description
Antarctica is the center from which all surrounding continental bodies separated millions of years ago. Antarctica: A Keystone in a Changing World, reinforces the importance of continual changes in the country's history and the impact of these changes on global systems. The book also places emphasis on deciphering the climate records in ice cores, geologic cores, rock outcrops and those inferred from climate models. New technologies for the coming decades of geoscience data collection are also highlighted. Antarctica: A Keystone in a Changing World is a collection of papers that were presented by keynote speakers at the 10th International Symposium on Antarctic Earth Sciences. It is of interest to policy makers, researchers and scientific institutions.

Book Description
Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 10. The existence of insects, mites, and their relatives on the antarctic continent is of great interest to many. These terrestrial arthropods may be said to be the dominant land animals in the absence of land vertebrates and many major groups of invertebrates. They are important in the simple food cycles which involve most segments of the land flora and microorganisms, and they play a part in soil formation. Thus a knowledge of their ecology is essential to the understanding of various biotic balances and processes. That several species live in the area of 85°S latitude in the face of harsh climatic factors is of great concern to the ecologist and the physiologist—therin lie many unanswered questions for future research.

Book Description
This volume summarizes the current state of knowledge of each of the main sectors of the basin. After reconstructing Permian-Triassic Gondwanaland, authors from South America, South Africa, Antarctica, and Australia illustrate the relevant geology of each sector in maps and time-space diagrams under

Book Description
This Memoir is the first dedicated to the Antarctic mantle. It is a cross-disciplinary reference work combining geochemistry and geophysics to characterize Antarctic mantle properties. Through observations and modelling the mantle structures, compositions and dynamics are characterized at regional and continental scales by subject experts. The Memoir reviews all known occurrences of sub-continental mantle xenoliths in igneous rocks. These studies are presented by region as southern or northern Victoria Land, Marie Byrd Land, the Antarctic Peninsula, East Antarctica and the sub-Antarctic Islands. Sub-oceanic mantle in tectonically emplaced and abyssal settings is also considered where known. This is complemented by a continental-scale mantle xenolith overview, mantle characteristics from igneous rocks and a quantitative mantle fabric study. State-of-the-art, continental-scale geophysical overviews of the Antarctic mantle are presented by discipline as seismology, gravity and magnetics, magnetotellurics, rheology, glacial isostatic adjustment, mantle convection and palaeotopography. This Memoir will be the reference for all researchers interested in the Antarctic mantle and its role in dynamics that shape the Antarctic surface and ice sheets.

Book Description
Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.
