Transcript of Antarctic Map Folio Series Committee on Antarctic Names (ACAN), which makes recommendations on...

  • After some of the more extensive changes of last year, the alterations this year are somewhat smaller by comparison, but nonetheless important for a more complete and accurate picture of the Continent. The most recent adjustments (see accompanying map) are as follows:

    1. Addition of bathymetric details and changes in Coats Land (Chart H.O. 6640, 1:5,000,000, U.S. Naval Oceanographic Office, October 28, 1968)

    2. Changes in positions of features and additional cartographic detail and new names in southern Palmer Land (U.S. Geological Survey 1:500,000 shaded relief map of Ellsworth Land east—Palmer Land south)

    3. A new configuration of the Larsen Ice Shelf (British D.O.S. sketch map of the Antarctic Penin- sula, 1:3,100,000, 1968);

    4. A small adjustment in the edge of the Filchner Ice Shelf (series on the Argentine expedition to the South Pole, 1:200,000, 1965)

    5. A change in the Fimbul Ice Shelf due to the breaking off of the "Trolitunga" ice tongue (satellite photography);

    6. Additional data along the final leg of the South Pole—Queen Maud Land Traverse of 1967 (pub- lished records)

    7. A new ice front to the Amery Ice Shelf (ANARE charts of the expedition of Nella Dan, 1: 1,000,000, 1968);

    8. Some improvements in the coastline of central Victoria Land and in the Gould and Dufek Coast regions (U.S.G.S. compilations and published maps, 1:250,000 1 1968).

    A new 9-sheet U.S.S.R. map at a scale of 1:3,000,000 shows more detail on the locations, eleva- tions, and ice thicknesses along the 1967 Molodezh- naya—Novolazarevskaya traverse, and some noticeable changes along the coast of Queen Maud Land near Novo lazarevskaya and in the West Ice Shelf.

    Antarctic Map Folio Series VIVIAN C. BUSHNELl.

    American Geographical Society

    Cartographic and editorial work are in progress on five folios. The three described here are nearest to completion.

    A folio on the bedrock geology of Antarctica, an important achievement in compilation and cartog- raphy, will be published before the end of the year. It includes 18 regional maps (see figure) at scale 1: 1,000,000, with accompanying text, compiled by 24 geologists from 8 nations. Each contributor is a spe- cialist in the locality covered by his map. The areas of the Continent included in the maps are shown in the figure. In addition, Campbell Craddock of the Uni- versity of Wisconsin, coeditor of the folio, has com- piled a geologic map of the entire Continent and written an explanatory text. Also, some of the most widespread geomorphic features of the Antarctic Con- tinent have been mapped and described by Robert Nichols of Tufts University.

    Another folio nearing completion is titled Circum- polar Characteristics of Antarctic Waters. In contrast to Folio 6, which dealt only with the waters between 20°W. and 170°W., the forthcoming folio covers all ocean areas surrounding Antarctica as far north as 40°S. The authors are Arnold L. Gordon. Robert D. Goldberg, and Kenneth Hunkins. Plate 1 is a station map with symbols to designate stations of oceano- graphic cruises occurring (1) before 1930, (2) from 1930 through 1949, and (3) from 1950 till the pres- ent. Plates 2 through 8 show isolines for temperature, salinity, and oxygen; Plates 2 and 3 give summer and winter means at 20 m depth, the others annual means at selected depths from 200 m to 3,000 m. On Plates 9 through 16, the above data are presented in a more specific manner. Again, each plate is devoted to a

    233

  • particular depth, at which average values of tempera- ture, salinity, and oxygen are given for areas bounded by 50 of latitude and 100 of longitude. For any 50 X 10 area, all three values are plotted on the same map around a point which is the average location of the stations within the area. Plates 17 and 18 are devoted to vertical meridional sections showing tem- perature, salinity, and oxygen variations. Plate 19 contains two maps of sound velocity in the axis of the SOFAR channel; one map is for summer, one for winter.

    A third folio is devoted to birds, including pen- guins, albatrosses, petrels, fulmars, skuas, terns, and others. Sighting and specimen records of some 50 spe- cies have been plotted along with breeding localities, when known. Under the supervision of George Watson, Smithsonian Institution, data for the maps have been assembled from extensive published and unpublished records. Compilers include J . Phillip Angle, Margaret Bridge, Peter C. Harper, John C. Boyd, W. L. N. Tickell, and Roberto Schlatter. Wil- liam J . L. Sladen helped in planning the folio.

    Antarctic Geographic Nomenclature FRED G. ALBERTS

    Geographic Names Division U.S. Army Topographic Command*

    The Geographic Names Division performs the re- search and other staff functions for the Advisory Committee on Antarctic Names (ACAN), which makes recommendations on antarctic names and policy to the Board on Geographic Names (BGN) and the Secretary of the Interior. The Division main- tains records and files on antarctic nomenclature and provides inquiry service on names for this region.

    During the year ending June 30, 1969, the ACAN met six times. It recommended the approval of 369 new names and the amendment of two others. New names were provided for use on fourteen 1:250,000- scale maps of the area west of Cape Adare which were in various stages of preparation at the U.S. Geo- logical Survey. Additional new names were provided to authors of reports on Antarctica as needed.

    In addition to research on new names, work was completed at the Geographic Names Division for pub- lication of a third edition of BGN Gazetteer No. 141 Antarctica. The updating of this publication is of spe- cial interest in that it provides the only comprehen- sive list of names covering the entire Continent. The new volume, to be issued shortly, lists all 10,000

    * Formerly U.S. Army Map Service.

    names approved by the BGN, including approxi- mately 1,500 new names and two dozen amended names approved since 1966. The bulk of the new names apply to landmarks in eastern Marie Byrd Land, Ellsworth Land, southern Palmer Land, the Pensacola Mountains, and northern Victoria Land— all areas mapped in the past few years by the U.S. Geological Survey. Older feature names within these areas have been reviewed, and precise map locations for discoveries reported earlier have been determined. Reflecting this aspect of the research, the new gazet- teer provides revised geographic coordinates for over 500 names listed in the previous edition.

    Hundreds of inquiries on antarctic names were re- ceived and answered by the Geographic Names Divi- sion. These inquiries generally pertained to the cor- rect spelling of names, the location of features, the origin or meaning of names, and their application. Galley proofs were reviewed for volumes 13 and 14 of the Antarctic Research Series. Name information was provided to the American Geographical Society for use in maintaining an up-to-date map of Antarctica, and various Government maps and charts of the region were edited prior to their publication.

    Smithsonian Oceanographic Sorting Center Continues its USARP Activities*

    In six years of cooperative work with USARP, the Smithsonian Oceanographic Sorting Center (SOSC) has received over 8,000 samples of antarctic animals and plants, the majority of them from marine collec- tions, primarily of benthic and planktonic inverte- brates. From 16 USARP sources, 183 separate collec- tions have been sent to the Center for processing and distribution. Most of the collections are from USNS Eltanin cruises, although some material has been re- ceived from USCGC Eastwind and R/V Hero, and from shore and continental expeditions. The Center recently received over 1,000 bryophyte specimens col- lected by the late Dr. R. Hatcher during the Chile— United States Botanical Expedition to Juan Fer- nández Islands-1965 and arranged into several du- plicate sets by Dr. Henry A. Imshaug of Michigan State University. SOSC distributed these sets to 11 cryptogamic herbaria in 5 countries.

    In contrast to the high collecting activity of earlier years, the Sorting Center received only 232 samples from 6 USARP expeditions during the past year. The Center did not receive any collections from four of last year's six Eltanin cruises.
