Drygalski Ice Tongue
The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, north of Ross Island. The 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. The Drygalski Ice Tongue ranges from wide. Captain Robert Falcon Scott, leader of the British National Antarctic Expedition (1901-1904), discovered the Drygalski Ice Tongue in January 1902 and named it for Professor Erich von Drygalski, a contemporary German explorer then in Antarctica. The glacier that feeds the ice tongue was named after Edgeworth David. David and Douglas Mawson crossed the ice tongue in 1908/09 as part of the ''Nimrod'' Expedition. The ''Terra Nova'' Northern Party expedition did the same in 1912 during their return journey to Cape Evans. The name Drygalski Ice T ...

Ice Tongue
An ice tongue is a long and narrow sheet of ice projecting out from the coastline. An ice tongue forms when a valley glacier moves very rapidly (relative to surrounding ice) out into the ocean or a lake. They can gain mass from water freezing at their base, or by snow falling on top of them. Mass is then lost by calving or by melting. Ice tongues can range in length from to . Icebergs are often formed when ice tongues break off in part or wholly from the main glacier. Two examples of ice tongues are the Erebus Ice Tongue and the Drygalski Ice Tongue The Drygalski Ice Tongue, Drygalski Barrier, or Drygalski Glacier Tongue is a glacier in Antarctica, on the Scott Coast, in the northern McMurdo Sound of Ross Dependency, north of Ross Island.
