The Contact of the Ross Ice Shelf with the Continental Ice Sheet, Antarctica
Abstract A profile of ice thickness along the 647 mile trail from Little America V to Byrd Station has been obtained from altimetric, seismic, and gravity measurements, and detailed studies made at the junction of the Ross Ice Shelf and the Marie Byrd Land plateau. The surface elevation profile clea...
