Description / Table of Contents:
A twin Otter aircraft of the British Antarctic Survey was equipped eith a Scott Polar Research Institute Mark 4 radio echo sounder during the Antarctic summer 1969-70. Flights tatalling about 10,000 km. were made from Adelaide station and Fossil Bluff. The Larsen Ice Shelf was found to be 200 m thick at the ice front, increasing to more than 500 m in Cabinet Inlet and Mobiloil Inlet. On the Wordie Ice Shelf east of long. 67°50'W., thicknesses were between about 150m at the ice front and 400 m in the north-east at the foot of Hariot Glacier. Probable brine infiltration prevented widespread depth measurement in Wilkins Sound. In George VI Sound, in spite of extensive surface melt pools, soundings indicated a thickness of almost 500 m near lat. 73°S, long. 70°W. On the Antarctic Peninsula plateau, thicknesses up to 1,630 m were recorded. In the Weddell Sea a giant iceberg which is thought to have come from the Amery Ice Shelf was sounded. Tracks were plotted from flight-recorder data with a general purpose digital computer which also did the collation with the radio echo 35 mm film record. The data obtained are presented together with data collected during the 1966-67 season by C. W. M. Swithinbank and D. L. Petrie.
