Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 71. The Antarctic Ice Sheet has greatly affected global climate, sea level, ocean circulation, and southern hemisphere biota during Cenozoic times. Much of our understanding of the evolution of the ice sheet has been inferred from isotopic studies on distant deep-ocean sediments, because few Cenozoic rocks are exposed on the Antarctic continent. Yet, large differences occur between past ice volumes inferred from isotopic studies and those inferred from low-latitude sea-level variation. The massive quantities of glacially transported terrigenous sediments that lie beneath the Antarctic continental margin provide an additional, more direct record of the inferred ice sheet fluctuations. Volume 68 addresses the history of ice sheet fluctuations as recorded by geological and geophysical investigations of selected areas of the Antarctic continental margin. As described below, the volume gives data and results from on-going research by a major multinational project directed toward better understanding the impact of Antarctic Ice Sheet fluctuations on global sea levels and climates.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 58. A systematic study was made of the calanoid copepod genus Euaugaptilus found in Isaacs-Kidd midwater trawl and Bongo plankton net samples taken in Antarctic and Subantarctic waters. A total of 303 adult copepods representing 14 species of Euaugaptilus were found, including five new species (E. hadrocephalus, E. perasetosus, E. aliquantus, E. brevirostratus, and E. austrinus) and seven new records (E. maxillaris, E. nodifrons, E. bullifer, E. gibbus, E. angustus, E. laticeps, and E. oblongus). Euaugaptilus antarcticus (Wolfenden) is restored from synonymy. All species are characterized with pertinent descriptions and illustrations. Keys are presented for identification of the species.

Description :


Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased. The book spans a broad spectrum of Antarctic science from the "ozone hole" to microbiology to the sea ice. The main focus is on the role of Antarctica and the Southern Ocean in the world climate system, e.g. the formation of sea ice and its relevance to ocean circulation, the biological pump in relation to CO2 release. The past climate history is revealed by the analysis of ice cores and sediments. Studies of plate tectonics and fossil records reach further back in earth history. Key words in the biological chapters are krill and the rich Antarctic benthos. Finally, the potential conflict between conservationists, researchers and tourists is discussed.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 49. The distribution of Siphonophora of the Antarctic, Subantarctic, and adjacent regions of the Pacific and Atlantic Oceans is described. Specimens for this study were obtained during the United States Antarctic Research Program from USNS Eltanin cruises 3-5, 8-23, 25-28, 35, and 38 during spring, summer, fall, and winter. Samples were collected from 1962 to 1969, using open-closing and nonclosing plankton nets. Information is compiled on horizontal distributions of siphonophores in the South Atlantic Ocean west of 0°. Illustrations of the species, and maps of distribution at the three bathymetric levels, are also included. In addition, data on Eltanin cruise 30 are presented, covering mainly the Pacific tropical region during the summer, with some stations below the equator (austral winter). Vertical distributions of each species are discussed for the three bathymetric zones: epipelagic (200-0 m), mesopelagic (1000-200 m), and bathypelagic (below 1000 m). Life stages and seasonal variations are also considered. Eighty species of Siphonophora were identified in these collections. Among these, and described elsewhere, were five new species: Lensia eltanin, L. eugenioi, L. landrumae, Heteropyramis alcala, and Thalassophyes ferrarii. The eudoxid stages of L. lelouveteau and L. reticulata were also discovered. In addition, the following rare Siphonophora species were collected: Halistemma cupulifera, Desmophyes annectens, Lilyopsis rosea, Eudoxia macra, Lensia achilles, L. baryi, L. exeter, L. grimaldii, L. hostile, Nectocarmen antonioi, and Clausophyes galeata. The most common species of the Antarctic Subantarctic region during the four seasons was Dimophyes arctica. The eudoxid stages of Chelophyes appendiculata, Diphyes dispar, Diphyopsis mitra, Clausophyes ovata, and Heteropyramis maculata were abundant.

Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 78. The seas surrounding Antarctica are the least-studied on Earth, yet they figure prominently in both the global climate system and the biogeochemical cycling of such key elements as C, N, Si, and P. The Southern Ocean affects climate directly through the sinking of surface waters via cooling and changes in salt content. Such water near Antarctica moves slowly northward through all major ocean basins. In doing so, it retains a long-lived signature of the physical and biological processes that occurred in Antarctic surface waters lasting many hundreds of years through all phases: sinking, northward flow, and mixing or upwelling into the sunlit ocean thousands of kilometers away. By this process, CO2 that dissolves into the Antarctic seas may be stored in the deep ocean for centuries. In fact, the Southern Ocean is one of the most important regions on Earth for the uptake and subsurface transport of fossil fuel CO2.

Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 70. The Long-Term Ecological Research (LTER) Program was established in 1981 by the United States National Science Foundation in recognition of the need to study ecological processes over time spans longer than those of most research grants. The LTER Network now consists of 18 sites that span a variety of ecosystem types in the continental United States, Alaska, Puerto Rico, and Antarctica. The addition of the Palmer LTER at Palmer Station, Antarctica in October 1990 extended the geographical and ecological range of the LTER Network and provided the opportunity to link physical and ecological processes in the northern and southern hemispheres. One criterion for establishment of a LTER site is the existence of historical data and observations that can provide a basis for guiding research programs. Thus, the intent of this volume is to bring together meteorological, hydrographical, biological and ecological observations made in the general area west of the Antarctic Peninsula and to discuss the processes underlying the observations. This compilation of available data and observations in conjunction with the present understanding of processes provides the foundation for long?]term studies of the ecosystem in the western Antarctic Peninsula region.

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 45. About 2700 tanaidaceans from 131 stations collected by scientists on board the R/V Hero at Tierra del Fuego, Isla de los Estados, and along the west coast of the Antarctic Peninsula were studied. A total of 36 species representing 26 genera in 11 families were determined. Of these taxa, four genera, one subgenus, and 12 species are described as new to science. Of the remaining 24 species, only nine were known previously from the area studied. Range extensions are reported for 14 species, only one of which is listed for the Antarctic/Subantarctic region for the first time.

Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 48. This volume attempts to present both a comprehensive overview of the south polar and subpolar volcanic provinces, and summary data on the status of knowledge of each volcano or volcano group. This broad region, covering roughly 6% of the Earth's surface, is infrequently visited and yet truly international. Its geoscience literature is dispersed in many journals, monographs, symposium volumes, and expedition reports, in many nations, and we hope that this summary will make it more widely available. The preparation of the volume has been a project of the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) through its Working Group on Antarctic Volcanology. It represents a substantial update and expansion of IAVCEI's 1960 Catalogue of Active Volcanoes for Antarctica (edited by W.H. Berninghausen and M. Neumann van Padang). The organization and format of the volume, conventions followed, and other items of information are presented below.

Description :


Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 73. The 4 million to 20 million square kilometers of sea ice that surrounds the Antarctic continent represents one of the largest and most dynamic ecosystems on Earth. This sea ice matrix provides a habitat for a wide variety of organisms, some of which live their entire lives within the ice while others are only occasional visitors. Large grazers, such as copepods and krill which come to the sea ice to feed, represent important links between sea ice biota and the pelagic environment. Unfortunately, because of the inherent difficulty of sampling such an environment, many aspects of this unique habitat are still poorly understood. The purpose of this volume is to present new information about this ecosystem so that its role within the Antarctic food-web (and as a sink for carbon dioxide) and its susceptibility to environmental changes can be better understood.
