	'''Antarctic sea 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.		'''Antarctic sea ice''' is the sea ice of the [[Southern Ocean]].
