In 1967 the Scott Polar Research Institute (SPRI) undertook the first longrange airborne radio echo soundings of the Antarctic ice sheet. The results of this season were encouraging and led to other programmes being organized in 1969–70, 1971–72, and 1974–75. The initial impetus for this work came from A. P. Crary of the US National Science Foundation (NSF), who suggested that the radio echo equipment that had been developed at SPRI under the direction of S. Evans and G. de Q. Robin, with financial assistance from the Royal Society's Paul Instrument Fund and later from the Natural Environment Research Council (NERC) should be operated over the Antarctic ice sheet, and he offered the logistic support of the US Antarctic Research Program (USARP). Since those early flights, a productive relationship has been developed between SPRI and that arm of NSF represented by USARP and US Navy Task Force 43 (now 199) and, up to the end of the 1971–72 season, it had resulted in 210000 km of radio echo profiling in the Antarctic. A further 135 000 km was accomplished during the 1974–75 season.
