"This document represents the final report of the United States Antarctic Program External Panel. The report has the unanimous approval of all 11 panel members and draws upon our collective experience which includes some 44 individual trips to Antarctica involving visits to all three U. S. stations, each research ship, support icebreakers and numerous field sites. As a panel, we visited McMurdo Station and South Pole Station and toured support facilities at Christchurch. We received approximately 70 briefings and conducted 80 “one-on-one” meetings with individuals involved in virtually all aspects of the Antarctic Program. Over 200 inputs were received in response to our request for “public comments". During visits to McMurdo and the Pole, the Panel conducted informal “Town Meetings” and was the beneficiary of numerous comments by members of those communities having first-hand experience in day-to-day operations. We are most appreciative of the candor and professionalism with which we were treated by all those with whom we came into contact, and in particular the members of the National Science Foundation who so expertly and constructively supported our efforts. We believe the U. S. Antarctic Program is well managed, involves high quality science and is important to the region as well as to the United States. We also believe that in the current budget environment, costs must be reduced, preferably through increased efficiency and “reinvention,” but, if not, through reduced scope. Recommendations are offered herein to help ensure the continued viability of the program into the 21st century."--

Originally published in 1984. Antarctica can no longer be considered merely a highly specialized area of interest to a relative handful of explorers and scientists. World political leaders who, in an era of resource politics, are looking to potential sources of supplies of living and non-living resources. Antarctica may prove to be a source of such supplies. In this volume, Dr. Westermeyer’s study of the options available for a mineral regime and probable costs comes at an opportune time, helping participants understand the issues and find acceptable solutions.

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).

Due to their unique geophysical and geodynamic environment, both the Arctic and Antarctic polar regions are often utilized for geodetic and geophysical observations. This book is a collection of papers on various aspects of the scientific investigation and observation techniques of the polar regions at both temporary and permanent observatories. Most papers focus on regional models based on data acquired in polar regions. Geodetic satellite positions systems (GNSS: GPS, GLONASS, GALILEO) will also be discussed as well as other space techniques (DORIS, VLBI). Gravimetry, absolute gravimetry, and tidal gravimetry are also discussed, as well as seismology and meteorology. The book also touches on data analysis and geodynamic interpretation and discusses methods of constructing autonomous observatories.

Antarctica is the southernmost continent on Earth, and it is the fifth largest. It is located at the South Pole in the southern hemisphere, and it consists of a glacier-covered landmass surrounded by the Southern Ocean. Antarctica is the coldest, driest, and windiest place on Earth, with a harsh and extreme environment that makes it difficult for human habitation. However, despite the harsh conditions, Antarctica is home to unique wildlife and natural resources that are of incredible scientific interest. The continent is governed by the Antarctic Treaty System, which promotes scientific cooperation, environmental protection, and peaceful relations among the countries that have claimed territories in Antarctica. The Treaty also prohibits military activity, nuclear testing, and mineral exploitation, which helps to preserve Antarctica as a pristine and valuable scientific laboratory. Each year, researchers from around the world travel to Antarctica to study its geology, climate, and biodiversity, as well as to conduct experiments in astronomy, astrophysics, and microbiology. Antarctica is also a popular tourist destination, attracting thousands of visitors who come to experience its stunning scenery, unique wildlife, and extreme environment.
