Morphology of bottom surfaces of glacier ice tongues in the East Antarctic region
During three Antarctic summer campaigns (1995/97/99) Radio Echo Sounding (RES) system data from some glacier ice tongues in the East Antarctic regions between Victoria Land and George V Land were collected.

Radio-Echo Sounding: Glaciological Interpretations and Applications [PDF]
Abstract After a brief review of factors relevant to the propagation of radio waves in ice, problems of profiling the upper and bedrock surfaces of ice sheets are considered. These include deconvolution of echo traces and accurate navigation.

Accidents and opportunities: a history of the radio echo-sounding of Antarctica, 1958–79 [PDF]
AbstractThis paper explores the history of radio echo-sounding (RES), a technique of glaciological surveying that from the late 1960s has been used to examine Antarctica's sub-glacial morphology. Although the origins of RES can be traced back to two accidental findings, its development relied upon the establishment of new geopolitical conditions, which

Deep multi-scale learning for automatic tracking of internal layers of ice in radar data
In this study, our goal is to track internal ice layers on the Snow Radar data collected by NASA Operation IceBridge. We examine the application of deep learning methods on radar data gathered from polar regions.

Ice stream or not? Radio-echo sounding of Carlson Inlet, West Antarctica [PDF]
The Antarctic Ice Sheet loses mass to the surrounding ocean mainly by drainage through a network of ice streams: fast-flowing glaciers bounded on either side by ice flowing one or two orders of magnitude more slowly.

Airborne radio echo sounding on the Shirase Glacier and its drainage basin, East Antarctica
Airborne radio echo sounding carried out on the Shirase Glacier and its drainage basin in January 1980 is described. The new sounder (NIPR-A) was operated at 179 MHz on board a Pilatus Porter PC-6.

Layer optimized SAR processing and slope estimation in radar sounder data
Englacial layers in Antarctica and Greenland are indicators of the dynamic, rheological and subglacial configuration of the ice sheets. Airborne radar sounder data is the primary remote sensing solution for directly observing englacial layers and ...
