An in situ measurement of the radio-frequency attenuation in ice at Summit Station, Greenland [PDF]
, 2016 . We report an in situ measurement of the electric field attenuation length Lα at radio frequencies for the bulk ice at Summit Station, Greenland, made by broadcasting radio-frequency signals vertically through the ice and measuring the relative power in

CReSIS airborne radars and platforms for ice and snow sounding
Annals of Glaciology, 2020 This paper provides an update and overview of the Center for Remote Sensing of Ice Sheets (CReSIS) radars and platforms, including representative results from these systems. CReSIS radar systems operate over a frequency range of 14–38 GHz.

Switch-off of a major enhanced ice flow unit in East Antarctica [PDF]
, 2006 The East Antarctic Ice Sheet (EAIS) is the largest reservoir of ice on the planet by an order of magnitude. Compared with the West Antarctic Ice Sheet (WAIS), it is traditionally considered to be relatively stable, with only minor adjustments to its ...

Basal melting over Subglacial Lake Ellsworth and its catchment: insights from englacial layering
Annals of Glaciology, 2020 Deep-water ‘stable’ subglacial lakes likely contain microbial life adapted in isolation to extreme environmental conditions. How water is supplied into a subglacial lake, and how water outflows, is important for understanding these conditions. Isochronal

Journal of Glaciology, 2017 Taylor Glacier hosts an active englacial hydrologic system that feeds Blood Falls, a supraglacial outflow of iron-rich subglacial brine at the terminus, despite mean annual air temperatures of −17°C and limited surface melt.

Past rates of accumulation in central West Antarctica [PDF]
, 2004 The spatial variation in ice accumulation is critical to the form and stability of ice sheets. In West Antarctica, knowledge of present ice accumulation rates is restricted to sparse measurements and interpolations across data free regions, while ...

A stratigraphic link across 1100 km of the Antarctic Ice Sheet between the Vostok ice-core site and Titan Dome (near South Pole) [PDF]
, 2000 Isochronous internal ice-sheet layering, measured from airborne 60 MHz radar, was traced between Lake Vostok and the Titan Ice Dome (100 km from South Pole Station), Antarctica. Three layers were selected between Ridge B and Titan Dome, and between Ridge

Towards a common terminology in radioglaciology
Annals of Glaciology, 2022 Over the past 70 years, many different components of the cryosphere have been imaged with a variety of radar systems using increasingly sophisticated processing techniques.

ImpDAR: an open-source impulse radar processor
Annals of Glaciology, 2020 Despite widespread use of radio-echo sounding (RES) in glaciology and broad distribution of processed radar products, the glaciological community has no standard software for processing impulse RES data.
