'''[[Drift ice]]''' is the sea ice of the [[Southern Ocean]]. It extends far north in winter and retreats almost to the coastline each summer. Sea ice is frozen seawater that is usually less than a few meters thick. This is in contrast to [[Ice shelf|ice shelves]], which are formed by glaciers, float in the sea, and are up to a kilometer thick. There are two subdivisions of sea ice: fast ice, which is attached to land; and ice floes, which are not.

Sea ice in the Southern Ocean melts from the bottom instead of from the surface like Arctic ice because it is covered in snow. As a result, melt ponds are rarely observed. On average, [[Antarctica|Antarctic]] sea ice is younger, thinner, warmer, saltier, and more mobile than Arctic sea ice. Due to its inaccessibility, it is not as well-studied as Arctic ice.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.

Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history. In 1990, after conducting a survey of Mount Berlin, he declared the volcano to be "potentially active." Later, in 1994, during field work around Mount Siple, Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of Paul A. Siple, for whom the mountain was named.
