ABRIS Project: new bedrock topography map for central Antarctica
2007
Summary A new bedrock topography map has been compiled for the central region of East Antarctica using ice thickness data available in the BEDMAP Project data base and new information obtained after 2000 by the Russian Antarctic Expedition (when the BEDMAP product finished). Moreover, airborne radio-echo sounding data acquired during the Soviet Antarctic Expeditions (before 1992) between Enderby Land and the Gamburtsev Subglacial Mountains and recorded on films have been revised and reinterpreted. This work allowed imaging of improved bedrock topography for this area. Unlike the previously published bedrock topography map produced by the BEDMAP Project, the new map shows real bathymetry of Lake Vostok and some earlier not recognized morphological features of the Gamburtsev Subglacial Mountains and area to the north of them.
