In 1996 and 1997 an airborne RES survey was flown in the context of the North Greenland IceCore Project (NGRIP). At 75.10 N and 42.30 W a deep ice core is being drilled forpalaeoclimate studies with the objective to recover an undisturbed Eemian sequence. The present survey was specially designed to determine with high lateral resolution the bedtopography and the layering of internal reflectors in the vicinity around the drill site. Atotal of 19,000 km of profiles were flown yielding a rectangular flight pattern with sidelengths of 222 km respectively 210 km on 16 flights. The spacing between two flight tracksis about 10 km for most of the area and about 2.5 km in the center of the grid. Detailed mapsof ice thickness and subglacial topography have been produced. Moreover a data set was acquired that enables an independent stratigraphic control on the ice core record of NGRIP.From the map of subglacial topography and from selected profiles the bed of NGRIP can be denoted as perfectly flat particularly when compared to the region of GRIP/GISP2. There is noobvious reason, why flow disturbances eventually might have altered the stratigraphic orderin the lower part of the ice sheet at least up to 30 km upstream NGRIP. On the basis of thepresent study NGRIP seems to be an ideally chosen drill site in order to recover an undisturbed Eemian sequence.
