Knowra East Antarctica East Antarctica East Antarctica is the larger eastern region of Antarctica, lying mainly in the Eastern Hemisphere and separated from West Antarctica by the Transantarctic Mountains. Its ice sheet covers a high, ancient continental interior.
East Antarctic Ice Sheet : The vast ice sheet covering most of East Antarctica, holding the majority of Earth's glacial ice. It blankets the region and dominates its climate, topography, and contribution to sea level.
Ice-sheet dynamics : The processes governing how continental ice sheets deform, flow, and change over time. These processes carry East Antarctic ice from its high interior toward the coast.
Vostok Station : A Russian research station in East Antarctica, near one of Earth's coldest recorded locations. Its deep ice cores preserve a long record of Antarctic atmospheric composition and temperature.
West Antarctica : The western region of Antarctica, including the Antarctic Peninsula and the West Antarctic Ice Sheet. The Transantarctic Mountains divide it from East Antarctica, and much of its bed lies below sea level.
Transantarctic Mountains : A mountain range crossing Antarctica and separating East Antarctica from West Antarctica. The range marks the major geographic boundary between the eastern and western regions.
Glacial isostatic adjustment : The slow rise or sinking of Earth's crust as ice loads change and the mantle responds. Changes in East Antarctic ice load deform the bedrock and alter local sea levels.
EPICA Dome C ice core : An ice core drilled at Dome C in East Antarctica by the European Project for Ice Coring in Antarctica. Its layers provide a record of climate and greenhouse gases spanning hundreds of thousands of years.
West Antarctic Ice Sheet : The ice sheet covering West Antarctica, much of which rests on bedrock below sea level. Its marine-based structure makes it more vulnerable to ocean-driven retreat than most East Antarctic ice.
Gamburtsev Mountain Range : A subglacial mountain range in East Antarctica, buried beneath kilometers of ice. Its discovery revealed a rugged mountain system beneath the apparently smooth ice-sheet interior.
Ice-penetrating radar : Radar methods that map the bed and internal layers beneath glaciers and ice sheets. Radar surveys expose East Antarctica's buried mountains, basins, and ancient ice layers.
