Abstract
During the austral summer field seasons of the 1995–2004 Polar Marine Geological Research Expedition (PMGRE) within the frame of the Russian Antarctic Expedition (RAE) carried out groundbased geophysical investigations in the sub-glacial Lake Vostok area in order to study the ice sheet and bed relief. Geomorphological analysis of the data allowed better understanding of sub-ice and sub-water structures. The most striking structure is the Vostok Basin which subdivides into five main substructures: lake plane, deepwater hollow, sub-water ridges, internal and external slopes. We detected six principal morphological substructures outside the Vostok Basin: lowlands, low hilly planes, high planes, ridged plane, Komsomolskiye Mountains and middle mountain land. A geomorphological chart has been produced.
