Airborne radio echo sounding of glaciers in Svalbard

Polar Record, 1980
During 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, 1997
Abstract 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.

Antarctic airborne radio echo sounding, 1977–78

Polar Record, 1978
During 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).

Interpretation of radio echo sounding in polar ice sheets

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969
Abstract 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.

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.

U.H.F. radio echo sounding of Yukon glaciers

2010
A 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.

Ultra high frequency radio echo sounding of glaciers

2010
For determining the thickness of ice, radio echo sounding of glaciers is well established as a technique for rapid gathering of data. However it has become evident that radio echo sounder parameters must be tailored to meet specific requirements in order to achieve best results.
