Book Description
This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).

Book Description
The fourth international symposium on Antarctic Earth Sciences took place in Adelaide, South Australia during the week 16-20 August 1982. This volume contains a record of the centenary activities celebrating Sir Douglas Mawson and the one hundred and seventy-four papers that were presented by delegates for discussion over the five days. Sir Douglas Mawson was part of the first team to reach the magnetic South Pole, a leading geologist and scientific figure during the heroic age of of antarctic exploration. The papers presented during the symposium were divided into fifteen categories covering east and west Antarctica, marine, land and glacial geology, plate tectonics, islands, peninsulas, climatic change and Precambrian and Cenozoic era activity. The two hundred persons from sixteen countries who attended the symposium brought together a wide range of the most current expertise and research to share, of which this volume provides a record.

Book Description
With the negotiation of the International Protocol on Environmental Protection in 1991, those nations conducting scientific research programs in Antarctica face new challenges for stewardship of the southern continent and protection of its environment. Science and Stewardship in the Antarctic examines how the implementation of the 1991 agreement in the United States can be done in such a way to ensure the compatibility of scientific and environmental protection goals in this global laboratory. The book also addresses the potential for the new requirements both to benefit and harm research activities in Antarctica.

Book Description
Antarctica and the surrounding oceans are critical parts of the Earth system. The Earth’s history establishes that Antarctica’s core comprises a suite of crustal blocks that were once parts of various supercontinents. The geological record can provide critical insights into the evolution and processes of change in the Antarctic environment and the biota dependent on it. The development of geodetic infrastructure across Antarctica is imperative to facilitate the monitoring of its physical processes and to coordinate various infrastructure associated with Earth-monitoring techniques. Geoscientific Investigations From the Indian Antarctic Program is a reference that comprises geoscientific aspects of Antarctica through Indian scientific expeditions. It integrates them into a holistic understanding of Antarctica geoscience and its trajectory of change. Furthermore, it seeks to review scientific achievements and discuss what further accomplishments might be made in Antarctic geoscientific research and necessitates the evaluation of Indian geoscientific research from global perspectives. Covering topics such as geodynamical processes, mineralogical studies, and structural geology, this book is an indispensable reference source for polar researchers, geoscientists, geologists, geophysicists, oceanographers, hydrographers, surveyors, students and educators of higher education, researchers, and academicians.

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
Many nations conduct research and engage in other scientific activities on our frozen continentâ€"Antarctica. Each year the U.S. National Committee for the Scientific Committee on Antarctic Research (SCAR) compiles a book that includes these nations' reports of scientific pursuits undertaken by their citizens in Antarctica during the previous austral summer and of planned activities for the next season. This book details the activities that occurred in 1990 and is of particular value to policymakers and scientists throughout the world who are planning Antarctic programs.
