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.

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.

Radio echo sounding map of Antarctica, (˜90°E–180°)

Polar Record, 1975
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 (

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.

Interpretation of radio echo sounding in polar ice sheets

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

RECONSTRUCTION OF SUBGLACIAL RELIEF FROM RADIO ECHO SOUNDING RECORDS

GEOPHYSICS, 1970
In 1967 a party from the Scott Polar Research Institute, Cambridge, England, carried out a radio echo sounding survey of the Antarctic ice sheet; their data have been used in the analyses discussed. The radio echo sounding apparatus, basically a pulse‐modulated radar operating at 35 Mhz, was installed in a U.S.
