Vostok Station

Vostok Station is a Russian research base in East Antarctica, above a vast subglacial lake. Its extreme cold and isolated location make it a major site for polar science.

Lake Vostok: A large freshwater lake buried beneath the East Antarctic ice sheet. The station sits above this lake, which has driven decades of ice-core and subglacial research.
East Antarctic Ice Sheet: The vast ice sheet covering most of East Antarctica. Its thick ice buries Lake Vostok beneath the station.
Soviet Antarctic Expedition: A series of Soviet scientific expeditions to Antarctica beginning in 1955. The expedition established Vostok Station during the International Geophysical Year.
Amundsen–Scott South Pole Station: A United States research station located at the geographic South Pole. Both are inland Antarctic bases, but Amundsen–Scott occupies the Pole while Vostok lies far from it.
Vostok Station ice core: An ice core drilled at Vostok Station, preserving a record of ancient Antarctic climate and atmospheric composition. Its layers provide long climate records from the ice above the station.
Subglacial lake: A body of liquid water trapped beneath a glacier or ice sheet. Lake Vostok is an exceptionally large example of this hidden environment.
International Geophysical Year: A worldwide scientific collaboration conducted from July 1957 through December 1958. Vostok’s establishment belonged to the Antarctic cooperation of this research year.
Concordia Station: A French-Italian research station on the high Antarctic plateau at Dome C. Concordia shares Vostok’s extreme inland environment but has different access and research infrastructure.
Antarctic ice core: A cylindrical sample of Antarctic ice used to reconstruct past climate and atmospheric conditions. Vostok’s core is a landmark example of this broader climate archive.
Ice core drilling: The extraction of cylindrical ice samples to study past atmospheric and climate conditions. Drilling at Vostok recovered the layers used to reconstruct ancient climates.
