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.

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.

For the past three decades, it has been possible to measure the earth's static gravity from satellites. Such measurements have been used to address many important scientific problems, including the earth's internal structure, and geologically slow processes like mantle convection. In principle, it is possible to resolve the time-varying component of the gravity field by improving the accuracy of satellite gravity measurements. These temporal variations are caused by dynamic processes that change the mass distribution in the earth, oceans, and atmosphere. Acquisition of improved time-varying gravity data would open a new class of important scientific problems to analysis, including crustal motions associated with earthquakes and changes in groundwater levels, ice dynamics, sea-level changes, and atmospheric and oceanic circulation patterns. This book evaluates the potential for using satellite technologies to measure the time-varying component of the gravity field and assess the utility of these data for addressing problems of interest to the earth sciences, natural hazards, and resource communities.

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.

Antarctica and the surrounding Southern Ocean remains one of the world's last frontiers. Covering nearly 14 million km² (an area approximately 1.4 times the size of the United States), Antarctica is the coldest, driest, highest, and windiest continent on Earth. While it is challenging to live and work in this extreme environment, this region offers many opportunities for scientific research. Ever since the first humans set foot on Antarctica a little more than a century ago, the discoveries made there have advanced our scientific knowledge of the region, the world, and the Universe-but there is still much more to learn. However, conducting scientific research in the harsh environmental conditions of Antarctica is profoundly challenging. Substantial resources are needed to establish and maintain the infrastructure needed to provide heat, light, transportation, and drinking water, while at the same time minimizing pollution of the environment and ensuring the safety of researchers. Future Science Opportunities in Antarctica and the Southern Ocean suggests actions for the United States to achieve success for the next generation of Antarctic and Southern Ocean science. The report highlights important areas of research by encapsulating each into a single, overarching question. The questions fall into two broad themes: (1) those related to global change, and (2) those related to fundamental discoveries. In addition, the report identified key science questions that will drive research in Antarctica and the Southern Ocean in coming decades, and highlighted opportunities to be leveraged to sustain and improve the U.S. research efforts in the region.

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.

Sixty articles arranged in eight thematic sections refer to most recent geological and geophysical results of Antarctic research. The Precambrian of the East Antarctic shield and its geological history is considered as well as sub-ice topography, geophysics and stratigraphy, sedimentology and geophysics of the surrounding Southern Ocean. Particular emphasis is given to the connection of the Antarctic and the surrounding continents when forming part of Gondwana.

Antarctic and Southern Ocean scientific research has produced a wide array of important and exciting scientific advances. Spanning oceanography to tectonics, microbiology to astrophysics, the extreme Antarctic environment provides unique opportunities to expand our knowledge about how our planet works and even the very origins of the universe. Research on the Southern Ocean and the Antarctic ice sheets is becoming increasingly urgent not only for understanding the future of the region but also its interconnections with and impacts on many other parts of the globe. The U.S. National Science Foundation (NSF) provides U.S. researchers with broad access to the continent and its surrounding ocean. A Strategic Vision for NSF Investments in Antarctic and Southern Ocean Research identifies priorities and strategic steps forward for Antarctic research and observations for the next decade. This survey presents a decadal vision for strategic investments in compelling research and the infrastructure most critical for supporting this research. This report makes recommendations for high-priority, larger-scale, community-driven research initiatives that address questions poised for significant advance with the next decades. This report also outlines a roadmap through which the vision and these priorities can be met.
