West Antarctic Ice Sheet
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 marine-based
ice sheet
, meaning that its bed lies well below
sea level
and its edges flow into floating ice shelves. The WAIS is bounded by the
Ross Ice Shelf
, the
Ronne Ice Shelf
, and outlet glaciers that drain into the
Amundsen Sea
.
