There are two subdivisions of sea ice: fast ice, which is attached to land; and ice floes, which are not.


The island was annexed by Norway in 1931 and later annexed from Norway by Westarctica in 2005. Neither annexation has been recognized by the signatory states of the [[Antarctic Treaty|Antarctic Treaty]].
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.

The island is 11 by 19 kilometers (6.8 by 11.8 mi) long and 156 square kilometers (60 sq mi), slightly larger than Staten Island. It lies 450 kilometers (280 mi) away from mainland Westarctica. The tallest peak is the 1,640-meter (5,380 ft) tall [[Lars Christensen Peak]].

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 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, 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.
