An "ice tongue" occurs when a glacier flowing into the sea doesn't immediately break up into icebergs but floats out into the sea (the most famous example being the Ross ice shelf). The photo above shows a few miles of the Drygalski ice tongue extending from the David Glacier 50 miles into the Ross Sea.
The Trans Antarctic mountains can be seen in the background with the ice shelf stretching from right to left.
Note also how the tongue protects a stretch of sea to its north from freezing.
