Description :
During the 1997 summer field season, a grid of 30 survey stations was established on the high ice plateau in order to locate exactly the ice-flow divide between the Llewellyn and Matthes glaciers. Two geophysical methods, seismic reflections and gravity, were also employed to determine the thickness of the ice on the plateau. These geophysical measurements revealed that the present-day surface ice movement is largely independent of the subglacial topology.
