Abstract
- As part of the geophysical project of the 1999-2000 joint
German-Italian Antarctic expedition, GANOVEX VIII-ItaliAntartide XV
helicopter-borne radio echo soundings (RES) were taken to measure the
thickness of the ice cover in Oates Land, Antarctica. Based on 2500 km
of RES data acquired in the drainage system of the Matusevich Glacier,
maps of ice thickness and bedrock elevation were compiled. Maximum ice
thickness was 2500 m, with an average ice cover of 2000 m in the south
eastern part of the survey area. A remarkably deep graben structure
beneath the Matusevich Glacier can be followed to 70°S, where it
bends to the west and joins the Wilkes Basin. The subglacial relief
between the Lazarev Mountains, at the western flank of the Matusevich
Glacier, and the Archangel Nunataks at the eastern side of the Wilkes
Basin shows a relatively uniform hilly landscape, separated from the
USARP Mountains by the Matusevich drainage basin.
