West Antarctica on the left. Typical landscape for the Antarctic Peninsula area, with fjords, high coastal mountains and islands. Click on the image for geographical details. West Antarctica is the smaller part of the continent, (50° – 180°W), divided into:
Eastern Antarctica is to the right of the Transantarctic Mountains and Western Antarctica is to the left. Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean.
Oceanic islands between the Equator, 60°S, 20°W, and 115°E are the only Southern Hemisphere lands (besides East Timor) outside the five southern nuclear-weapon-free zones. Bouvet Island and the Kerguelen Islands are Antarctic islands on this map but outside the Antarctic NWFZ. Australian islands are parts of the South Pacific NWFZ.
The Antarctandes are even longer, having in common with the Transantarctic Mountains the ranges from Cape Adare to the Queen Maud Mountains, but extending thence through the Whitmore Mountains and Ellsworth Mountains up the Antarctic Peninsula. The 100–300 km (60–200 mi) wide range forms the boundary between East Antarctica and West Antarctica.
McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999. The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross ...
A map of the Antarctic region, including the Antarctic Convergence and the 60th parallel south The Antarctic 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.
