Ice Flow of the Antarctic Ice Sheet This copy is for your personal, noncommercial use only.Feb 18, 2000 There have, however, been no largescale observations of the velocity field for most of the interior of the 13 million km 2 Antarctic Ice Sheet that can test this view of icesheet dynamics. In particular, the East Antarctic Ice Sheet, which encompasses about 90 of the ice in Antarctica, remains extremely poorly sampled. ice flow of the antarctic ice sheet science

One such stream, the Recovery Glacier ice stream, annually drains the equivalent of eight percent of the huge East Antarctic Ice Sheet, an area larger than the continental United States.

Sep 09, 2011 The mapping of Antarctic ice motion therefore redefines our view of ice sheet flow dynamics and the way ice sheets have been modeled in the past, with implications for improving reconstructions of past and ongoing changes and especially for modeling the evolution of ice sheet dynamics in a warming climate. Pine Island is one of the fastestchanging glaciers on the West Antarctic Ice Sheet, accounting for about 20 percent of the ice sheet's total ice flow to the ocean. The immense glacier is also one of least stable, quickly retreating and losing massive amounts of ice.

The Western Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West (or Lesser) Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains which lies in the Western Hemisphere. The WAIS is classified as a marinebased ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. ice flow of the antarctic ice sheet science The Antarctic Ice Sheet is an important indicator of climate change and driver of sealevel rise. The ice streams drain the majority of the ice from the ice sheet, and changes in their behaviour can have massive impacts on the whole ice sheet. Ice streams can flow at 100s metres per year in Antarctica, compared with interior ice which flows at a few metres per year.
