MURPHY ROCKS This name originates from Australia. It is included in the Australian Antarctic Gazetteer (ID number 2458) and the SCAR Composite Gazetteer of Antarctica (ID number 9990). Latitude: 68° 13' 54.7" S -68.2319° Longitude: 78° 43' 55.5" E 78.7321° The feature consists of two closely adjacent but very isolated rocks lying in the sea about off the ice-cliff coastline (January 1990) of the Ingrid Christensen Coast, Princess Elizabeth Land, in the Vestfold Hills region of Antarctica. The rocks are dark grey and rounded, with diameters of about and are located approximately north-east of Davis Station. In January 1979 the first landings were made by helicopter on these rocks, during which survey station NM/S/268 was established.〔(【引用サイトリンク】title=Murphy Rocks )〕 The rocks are named for Brian Murphy, who made extensive surveys in the Vestfold Hills in 1978-79, including Doppler satellite fixes, a Tellurometer survey, heights by simultaneous reciprocal vertical angles and a site survey for a major re-building of Davis Station. These rocks currently define the north-eastern-most limit of ice-free rock areas of the Ingrid Christensen Coast, Princess Elizabeth Land, and, as such, form part of an extensive network of Adelie penguin rookeries located along this section of the coastline of Antarctica. The summit of the southern-most rock, upon which Transit Doppler satellite survey station NM/S/268 was established in January, 1979, and to which the above WGS84 coordinates refer, is above mean sea level. The summit of the northern-most rock, upon which survey station NM/S/270 was established, is above mean sea level. Survey station NM/S/270 lies on a true bearing of 75° 49' distant from survey station NM/S/268. == See also == *Murphy Rocks, rocks in Mary Byrd Land, West 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「Murphy Rocks, Australian Antarctic Territory」の詳細全文を読む スポンサード リンク
