The Watson Escarpment continues east along the rim of the California Plateau past Beacon Dome and Mount Warden. [2] It continues below Maaske Dome and above Evans Butte. To the east of Mount Beazley there is a gap in the escarpment through which the Leverett Glacier flows north towards the Ross Ice Shelf. The escarpment continues east past ...
Bathymetry of the Kerguelen Plateau Location of the plateau – the white spot is Kerguelen Island. The Kerguelen Plateau (/ ˈ k ɜːr ɡ əl ən /, / k ər ˈ ɡ eɪ l ən /), [1] also known as the Kerguelen–Heard Plateau, [2] is an oceanic plateau and large igneous province (LIP) located on the Antarctic Plate, in the southern Indian Ocean.

The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...
This is a list of Antarctic and sub-Antarctic islands. Antarctic islands are, in the strict sense, the islands around mainland Antarctica, situated on the Antarctic Plate, and south of the Antarctic Convergence. According to the terms of the Antarctic Treaty, claims to sovereignty over lands south of 60° S are not asserted. [1]
There are numerous islands surrounding Antarctica, most of which are volcanic and very young by geological standards. [24] The most prominent exceptions to this are the islands of the Kerguelen Plateau, the earliest of which formed around 40 Ma. [24] [25]
The high, flat, and cold environment of the Antarctic Plateau at Dome C Surface of Antarctic Plateau, at 150E, 77S. The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station.
Antarctica along with its outlying islands have no permanent population. All land claims south of 60°S latitude are held in abeyance by the Antarctic Treaty System. Australia's Heard Island and McDonald Islands (an external territory) and the French Kerguelen Islands are located on the Kerguelen Plateau, on the Antarctic continental plate ...
Geographical map of Antarctica. Lying on the Pacific Ocean side of the Transantarctic Mountains, West Antarctica comprises the Antarctic Peninsula (with Graham Land and Palmer Land) and Ellsworth Land, Marie Byrd Land and King Edward VII Land, offshore islands such as Adelaide Island, and ice shelves, notably the Filchner-Ronne Ice Shelf on the Weddell Sea, and the Ross Ice Shelf on the Ross Sea.
