Processed bed elevation picks from airborne radar depth sounding over the Jutulstraumen rift area (2001/02 season)

Summary

Abstract:
A British Antarctic Survey Twin Otter and survey team acquired 15,500 line-km of aerogeophysical data during the 2001/02 Antarctic field season along a 1-km line spacing grid with tie-lines 8 km apart. Twenty-five flights were flown from the South African base SANAE, for a total of 100 survey hours. We present here the processed bed elevation picks from airborne radar depth sounding. The airborne-radio echosounding data were collected for 5 flights, to image ice-thickness and bedrock configuration.
Data are provided as XYZ ASCII line data. This high-resolution aerogeophysical survey was part of the "Magmatism as a Monitor of Gondwanabreak-up" project (MAMOG) of the British Antarctic Survey, which included new geochemical investigations, structural geology, geochronology, and AMS studies over western Dronning Maud Land.
