The '''[[South Pole]]''' is one of the two points where the Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of the Earth and lies in [[Antarctica]] on the opposite side of the Earth from the North Pole.  The South Pole is both the southernmost and easternmost point of [[Westarctica]].
'''[[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.


The Ceremonial South Pole is an area set aside for photo opportunities at the [[Amundsen–Scott South Pole Station]]. It is located some meters from the Geographic South Pole, and consists of a metallic sphere on a short bamboo pole, surrounded by the flags of the original [[Antarctic Treaty]] signatory states. The first people to reach the Geographic South Pole were the Norwegian [[Roald Amundsen]] and his party on December 14, 1911. Amundsen named his camp Polheim and the entire plateau surrounding the Pole King Haakon VII Vidde in honor of King Haakon VII of Norway.
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.

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.
