Paper Abstract

During five austral summers, from 1994/95 until 1998/99, the Alfred Wegener Institute (AWI) carried out a large airborne radio echo sounding (RES) survey in Dronning Maud Land (DML), Antarctica. These ice thickness measurements are part of the AWI contribution to the pre-site survey for a deep ice core drill site in DML within the European Project for Ice Coring in Antarctica (EPICA). The survey encompasses more than 90000 km RES profiles over DML and the adjacent coastal area, covering more than 1 million km2. The lower boundary of the ice sheet could be determined area-wide. Internal horizons occurring in the upper two thirds of the ice column can also be traced for several hundred kilometers. This work presents the latest maps of the subglacial topography of the investigated area as well as of an internal horizon.
