The Drygalski Ice Tongue (an extension of the Davide Glacier) which extends into the sea for about 80 kilometres. The Drygalski Ice Tongue forms the southern edge of Terra Nova Bay in the Ross Sea, Antarctica. Glaciers are formed when pieces of the ice tongue break off its far end due to sea and wind erosion. Much of the sea on the Northern side of the tongue is open in summer, rather than ice as the massive tongue, which rises to about 10 stories high above the water, offers a degree of protection from the worst of the weather.

While Global warming is not effecting the Antarctic as much as it is the Arctic, especially Greenland; there are effects, with much bigger icebergs calving from ice shelves and ice tongues than have ever been recorded in the past. Some penguins species, especially the Gentoos, are moving further south in the summer to find breeding sites.
