The Drygalski Ice Tongue or Drygalski Barrier or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Antarctica's Ross Dependency, north of Ross Island. The ice tongue is at . Drygalski Ice Tongue is stable by the standards of Antarctica's icefloes, and stretches out to sea from the David Glacier, reaching the sea from a valley in the Prince Albert Mountains of Victoria Land. Drygalski Ice Tongue ranges from wide. Captain Robert Falcon Scott, leader of the British National Antarctic Expedition (BrNAE) (1901-1904), discovered Drygalski Ice Tongue in January 1902 and named it for Prof. Erich von Drygalski, a contemporary German explorer then in Antarctica. Drygalski Ice Tongue became well established by the name Drygalski Ice Tongue before it became usual to give the same name to a glacier and its glacier tongue. Although this feature is a glacier tongue, the generic term ice tongue has been retained in the name to reduce ambiguity. Drygalski Ice Tongue is thought to be at least 4,000 years old. On March–April 2005, a iceberg designated B-15A hit the ice tongue breaking off two pieces, each with a surface of about . This iceberg is a remnant of Iceberg B-15, which calved from the Ross Ice Shelf in 2000. Scientists are also concerned for several penguin colonies which have been isolated from the open sea by the two large bodies of ice. At the end of March 2006, another iceberg coming from the Ross Ice Shelf, named C-16, hit the ice tongue breaking off another large piece (more than ). ==See also== * List of glaciers in the Antarctic *Erebus Ice Tongue * List of glaciers *McMurdo Sound 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「Drygalski Ice Tongue」の詳細全文を読む スポンサード リンク
