Map of Antarctica with Eastern Antarctica seen to the right. Image of a variety of ice types off the coast of East Antarctica. East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying primarily in the Eastern Hemisphere south of the Indian Ocean, and separated from West Antarctica by the Transantarctic Mountains.
Western Antarctica and Eastern Antarctica correspond roughly to the western and eastern hemispheres relative to the Greenwich meridian. [note 1] West Antarctica is covered by the West Antarctic Ice Sheet. There has been some concern about this ice sheet, because there is a small chance that it will collapse. If it does, ocean levels would rise ...
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.
All but a small portion of the region lies within the Eastern Hemisphere. East Antarctica is largely covered by the East Antarctic Ice Sheet. [23] There are numerous islands surrounding Antarctica, most of which are volcanic and very young by geological standards. [24]

The division of Earth by the Equator and the prime meridian Map roughly depicting the Eastern and Western hemispheres. In geography and cartography, hemispheres of Earth are any division of the globe into two equal halves (hemispheres), typically divided into northern and southern halves by the Equator and into western and eastern halves by the Prime meridian.
The centre of the Eastern Hemisphere is located in the Indian Ocean at the intersection of the equator and the 90th meridian east, 910 km west of Indonesia in the Ninety East Ridge. The nearest land is Simeulue Island at 2°35′N 96°05′E / 2.583°N 96.083°E / 2.583; 96
The United States and Kiribati have most of their territory east of the 180th meridian, in the Western Hemisphere, so they are considered to belong to the westernmost countries with their territory stretching as far to the west as beyond the 180th meridian into the Eastern Hemisphere. Conversely, Russia, New Zealand, and Fiji have most of their ...
