Airborne radio echo sounding on the Shirase Glacier and its drainage basin, East Antarctica
Airborne radio echo sounding carried out on the Shirase Glacier and its drainage basin in January 1980 is described. The new sounder (NIPR-A) was operated at 179 MHz on board a Pilatus Porter PC-6. Analysis of the continuous records of the sounding gave the bedrock topography along the flow line as...
