Radio-Echo Sounding Over Polar Ice Masses [PDF]
Journal of Environmental and Engineering Geophysics, 2007 Radio-echo sounding (RES) constitutes the principal means by which glaciologists investigate the subsurface properties of the polar ice sheets and ice caps. Developed in the 1960s as a method for locating and mapping the subglacial interface beneath extensive regions of ice-covered terrain, thereby to constrain ice volume and morphology, it was ...

Progress in Radio-Echo Sounding Theory [PDF]
Journal of Glaciology, 1975 AbstractThe inverse problem of radio-echo sounding consists in the reconstruction of subglacial relief from the known radio-echo profile, and the path, and speed of the aircraft. The present work shows that in the geometrical optical approach the solution of the inverse problem for a homogeneous, two-dimensional object (valley glacier) exists, and ...

Fifty-five years of Russian radio-echo sounding investigations in Antarctica [PDF]
Annals of Glaciology, 2020 Russian (former Soviet) systematic studies of Antarctica by radio-echo sounding (RES) and ground-penetrating radar technique (GPR) were commenced in 1964.

Ice stream or not? Radio-echo sounding of Carlson Inlet, West Antarctica [PDF]
The Cryosphere, 2011 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.

Radio Echo-Sounding of Svalbard Glaciers [PDF]
Journal of Glaciology, 1982 AbstractPeculiarities of radio echo-sounding of mountain glaciers and ice fields between nunataks from terrestrial vehicles and from helicopters are considered in this paper. The possibility of using comparatively high frequencies (of up to 865 MHz) for sounding such glaciers is demonstrated on the basis of experimental data.

Radio echo sounding data analysis of the Shackleton Ice Shelf
Annals of Geophysics, 2010 In this study, our initial results are presented for the interpretation of the radio echo sounding data collected over the Shackleton Ice Shelf and adjacent ice sheet (East Antarctica) during the 2003/2004 Australian-Italian expedition.

Age stratigraphy in the East Antarctic Ice Sheet inferred from radio-echo sounding horizons [PDF]
Earth System Science Data, 2019 The East Antarctic Ice Sheet contains a wealth of information that can be extracted from its internal architecture such as distribution of age, past flow features, and surface and basal properties.

Airborne radio echo sounding on the Shirase Glacier and its drainage basin, East Antarctica
Antarctic Record, 1981 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.
