Since the austral summer 1994/95 the Alfred Wegener Institute (AWI) hascarried out airborne radio echo sounding measurements (RES) in Antarctica withits newly designed RES system. Since 1995/96 an ongoing presite survey foran ice coring drill site in Dronning Maud Land (DML) has been carried out.This survey is part of the EPICA programme (European Project for Ice Coring inAntarctica). It covers an area of 948000 km2 with more than 49500 km ofairborne RES obtained from more than 200 hours of flight operation flown from1994-1997. Within this paper first results of the airborne RES survey will begraphically summarized as newly derived maps of the ice thickness and thesubglacial topography as well as a 3D view of surface and subglacial bed andoutcrop topography, revealing a total icevolume of 1.48 million km3.
