Compilation of antarctic glaciological and geophysical folio
Antarctic Research Series JUDY C. HOLOVIAK
American Geophysical Union Washington, D.C. 20009
The Antarctic Research Series, published by the American Geophysical Union (Acu) with the aid of a grant from the National Science Foundation, was an outgrowth of research done in the Antarctic during the International Geophysical Year and has been disseminating the results of all phases of antarctic research since 1964. As of May 1980, 31 volumes have been completed in the series and 4 others are in the publication process. The most recent titles are Biology of the Antarctic Seas, VIII (volume 28), edited by D. L. Pawson and Louis S. Kornicker; Terrestrial Biology III, (volume 30), edited by B. Parker; and Biology of the Antarctic Seas IX, (volume 31), edited by Louis S. Kornicker. The Antarctic Research Series provides extensive and authoritative reports of research results in human behavioral sciences, marine and terrestrial biology, solid earth geo-

A systematic grid network of airborne geophysical sounding, covering 50 percent of Antarctica (as shown in the figure), has been completed during the last decade. The data comprise radio-echo soundings by the National Science Foundation, Scott Polar Research Institute and the Technical University of Denmark. Since 1911, simultaneous magnetic profiling was carried out on these flights by the Applied Physics Laboratory of Johns Hopkins University and the U.S. Geological Survey under the direction of John 224
physics and geochemistry, oceanic and atmospheric studies, and geology. The scientific and library communities have come to look to the series for continuing access to south polar research results. The American Geophysical Union has been striving to accelerate the publication of the volumes in the series and at the same time maintain printing costs at a level that would allow volumes to be priced within the individual researcher's budget. In 1974, the minibook format was introduced; it allows individual papers to be published at a steady pace rather than held for inclusion in complete volumes, providing more timely dissemination of current research results. Faced with continually rising printing costs, AGU is investigating several methods of lowering production costs, such as the use of author-prepared copy or wordprocessing equipment. The series volumes currently in preparation include the following: Biology of the Antarctic Seas X (volume 32), edited by Louis J. Kornicker; Dry Valley Drilling Project (volume 33), edited by L. D. McGinnis; Biology of the Antarctic Seas XI (volume 34), edited by Louis J. Kornicker; and A Contribution to the Flora and Vegetation of Isla De Los Estados (volume 35), by T. R. Dudley and G. E. Crow. Publication of the Antarctic Research Series currently is supported by National Science Foundation grant DPP 77-21859.
Behrendt. This material is now being synthesized in Cambridge prior to the production of a comprehensive Antarctic Glaciological and Geophysical Folio in late 1981. The folio is intended to provide a unique, high-quality data source with a large-scale atlas format. It is aimed to be of value and interest to research organizations, industry, and individuals. There will be upwards of 24 four-color sheets depicting parameters of ice sheet and bedrock that have been directly measured or intepreted principally from measured radio-echo and magnetic data. Each sheet will display a map (scale 1:1, 1:6, or 1:10 million, according to the complexity and quantity of data) and will include tabulated and graphical data, cross profiles, and computer sections where appropriate. Explanatory text and references of approximately 2,000 words will accompany each sheet. Following an introduction, which will present a brief history of antarctic radio-echo sounding, description of equipment used, season-by-season coverage maps, and evaluation of data quality, the folio will pay equal attention to glaciological and geophysical aspects. Glaciological sheets will include: ice sheet configuration including constructed flow lines; ice thickness; location of sub-ice water and geothermal heat; internal ice sheet layering; basal shear stress; reflection loss and dielectric absorption; surface accumulation; and surface temperature.

Specific regional sheets will include: Ross Ice Shelf; RonneFilchner Ice Shelf; the west antarctic ice sheet; McMurdo Sound area; and Transantarctic Mountains and outlet glaciers.

Geophysical sheets will include: bedrock configuration; isostatic compensated bedrock configuration; terrain roughness; bedrock reflection strengths; and sub-ice bedrock geologic syntheses.
