Quality Measurable bottom echoes were recorded for around 75% of the total flight path length of some 8800 km. The ANARE Mk 2 100 MHz ice radar produced peak power of 3 kW with a pulse repetition rate of 10 kHz. The receiver was linear with manual gain control. The radar unit operated from a Pilatus-Porter fixed wing aircraft moving at an average speed of 180 km/hr (100 knot) with flight durations of ... around 4 hours and sounding height above the terrain typically 150 m. Separate transmit and receive antennas consisted of 1 driven element and 1 director using the aircraft wing as a reflector. Film records were manually scaled approximately every 1 km of flight path. Signal propagation delay times were converted to ice thicknesses assuming a velocity of 169 m/microsecond with no firn correction. The data have been checked for consistency with general agreement from ANARE seismic and gravity traverses south of Mawson Station (1957-59) and with crossovers from earlier Soviet Antarctic Expedition (SAE) RES flights in the area. Dead reckoning was adopted using visual landmarks (generally mountains) and a gyroscopic drift sight. A dedicated navigator was used on all flights. Positions were manually written to flight logging sheets and have an accuracy of 1 km or better.
An entry of -9999 in the spreadsheet indicates null data.
