Berkner Island or Berkner Ice Rise or Hubley Island is an ice rise, where bedrock below sea level makes the ice dome upward. If the ice cap melted, it would be under water.〔http://earthshots.usgs.gov/Filchner/Filchnertext〕 Berkner "Island" is high and completely ice-covered and about long and wide, with an area of . Berkner is surrounded by the Filchner-Ronne Ice Shelf. The northernmost point of the Berkner is about from the open sea. It lies in the overlapping portion of the Argentine and the British claims. The island rises to ( according to other sources) and separates Ronne Ice Shelf from the Filchner Ice Shelf. It is characterized by two domes, ''Reinwarthhöhe'' in the north (), at , and ''Thyssenhöhe'' in the south (), at . It is indented by three bays on the eastern side, which are from north to south: McCarthy Inlet, Roberts Inlet, and Spilhouse Inlet. Gould Bay is on the north coast. Berkner Island is about west of Luitpold Coast, Coats Land, the closest mainland of Eastern Antarctica. off the northwest corner of Berkner Island is Hemmen Ice Rise. Berkner Island was discovered by members of the United States-International Geophysical Year (US-IGY) party at Ellsworth Station under the leadership of Capt. Finn Ronne, United States Navy Reserve (USNR), during the 1957-1958 season. Berkner Island was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for American physicist Lloyd Berkner, engineer with the Byrd Antarctic Expedition (1928–1930).〔http://data.aad.gov.au/aadc/gaz/scar/display_name.cfm?gaz_id=107766〕 Since 1990, Berkner Island has been a jumping off point for a number of long distance polar expeditions. Ben Saunders has planned an unsupported journey from the island to the South Pole and back.〔http://www.areteclub.com/newsite/portfolio/ben-saunders〕 In the 1994/1995 field season the British Antarctic Survey, Alfred Wegener Institute and the Forschungsstelle für Physikalische Glaziologie of the University of Münster cooperated in a project drilling ice cores on the North and South Domes of Berkner Island.〔http://gcmd.nasa.gov/KeywordSearch/Metadata.do?Portal=GCMD&KeywordPath=Parameters|PALEOCLIMATE|LAND+RECORDS|BOREHOLES&OrigMetadataNode=GCMD&EntryId=89738616867620&MetadataView=Full&MetadataType=0&lbnode=mdlb3〕 == See also == * Composite Antarctic Gazetteer * List of Antarctic islands south of 60° S * SCAR * Territorial claims in Antarctica 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Berkner Island」の詳細全文を読む スポンサード リンク
