Progress report on radio echo sounding
Polar Record, 1967This report is intended to summarize activities in radio echo sounding since the introductory paper which appeared in the Polar Record four years ago (Evans, 1963 a). The field work since that time is discussed in rough chronological order, with references to the sources of more detailed information and an assessment of the principal results.

Airborne radio echo sounding of glaciers in Svalbard
Polar Record, 1980During April–May 1980 the Scott Polar Research Institute (SPRI) and Norsk Polarinstitutt (NPI) conducted a joint programme of radio echo sounding (RES) in Svalbard. The principal aims were to evaluate the performance of SPRI 60 MHz echo sounding equipment of Svalbard glaciers, to measure ice thickness over a wide range of conditions, and to investigate

Airborne radio echo sounding of outlet glaciers in Greenland
International Journal of Remote Sensing, 1997Abstract We used a coherent radar depth sounder operating at 150MHz to collect ice thickness data on outlet glaciers in northwestern Greenland. The radar data were collected in conjunction with laser surface elevation measurements and were tagged with GPS information for accurate geolocation.

Interpretation of radio echo sounding in polar ice sheets
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969Abstract Experimental results are presented from a traverse over the ice sheet of north western Greenland in 1964, during which a continuously recorded profile of ice thickness was obtained for the first time. Interpretation of data from this traverse is consistent with results of subsequent work to December 1967.

Antarctic airborne radio echo sounding, 1977–78
Polar Record, 1978During the austral summer 1977–78 the Scott Polar Research Institute (SPRI) conducted a fifth season of airborne radio echo sounding in Antarctica as part of a joint project with the US National Science Foundation Division of Polar Programs (NSF-DPP) and the Technical University of Denmark (TUD).

U.H.F. radio echo sounding of Yukon glaciers
2010A high-resolution radio echo sounder operating at a frequency of 840 MHz has been developed for sounding of small and medium-sized polar glaciers and ice caps. The sounder uses a compact, high-gain antenna which improves the system performance, suppresses valley wall echoes and simplifies operation from light aircraft.

A Benchmark Dataset for Radio Echo Sounding Data
Melting glaciers and ice sheets contribute significantly to the global sea level rise, posing an existential threat to coastal regions. For that reason, many expeditions collect radio echo sounding data to track, model, and predict the changes in ice mass and thickness.Marcel Dreier +6 more
