The '''Western Antarctic Ice Sheet''' (WAIS) is the segment of the continental ice sheet that covers [[Westarctica]] and 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-shelf|ice shelves]]. The WAIS is bounded by the [[Ross Ice Shelf]], the [[Ronne Ice Shelf]], and outlet | The '''Western Antarctic Ice Sheet''' (WAIS) is the segment of the continental [[ice sheet]] that covers [[Westarctica]] and the portion of [[Antarctica]] on the side of the [[Transantarctic Mountains]] which lies in the Western Hemisphere.

It is estimated that the volume of the [[Antarctic ice sheet]] is about 25.4 million km3 (6.1 million cu mi), and the WAIS contains just under 10% of this, or 2.2 million km3 (530,000 cu mi). The weight of the ice has caused the underlying rock to sink by between 0.5 and 1 kilometer (0.31 and 0.62 miles) in a process known as isostatic depression. | It is estimated that the volume of the [[Antarctic ice sheet]] is about 25.4 million km3 (6.1 million cu mi), and the WAIS contains just under 10% of this, or 2.2 million km3 (530,000 cu mi).
