Abstract We have measured the in situ average electric field attenuation length, 〈Lα 〉, for radio-frequency signals broadcast vertically through the Ross Ice Shelf, Antarctica. We chose a location, Moore Embayment, south of Minna Bluff, known for its high reflectivity at the ice–sea interface. We confirmed specular reflection and used the return pulses to measure the average attenuation length from 75–1250 MHz over the round-trip distance of 1155 m. We find 〈Lα 〉 to vary from ∼500 m at 75 MHz… 
An in situ measurement of the radio-frequency attenuation in ice at Summit Station, Greenland
Abstract We report an in situ measurement of the electric field attenuation length L α at radio frequencies for the bulk ice at Summit Station, Greenland, made by broadcasting radio-frequency signals
A 3D map of englacial attenuation rate from radar reflections at Law Dome, East Antarctica
Abstract. The East Antarctic Ice Sheet (EAIS) is the largest source of potential sea-level rise, containing approximately 52 m of sea-level equivalent. To constrain estimates of sea-level rise into
Radar Absorption, Basal Reflection, Thickness, and Polarization Measurements from the Ross Ice Shelf
Radio-glaciological parameters from Moore's Bay, in the Ross Ice Shelf, have been measured. The thickness of the ice shelf in Moore's Bay was measured from reflection times of radio-frequency pulses
Adaptively constraining radar attenuation and temperature across the Thwaites Glacier catchment using bed echoes
ABSTRACT Englacial temperature is a major control on ice rheology and flow. However, it is difficult to measure at the glacier to ice-sheet scale. As a result, ice-sheet models must make assumptions
Radar attenuation and temperature within the Greenland Ice Sheet

Title Radar attenuation and temperature within the Greenland Ice Sheet Permalink
The flow of ice is temperature-dependent, but direct measurements of englacial temperature are sparse. The dielectric attenuation of radio waves through ice is also temperature-dependent, and radar
Experimental Probes of Radio Wave Propagation near Dielectric Boundaries and Implications for Neutrino Detection
Experimental efforts to measure neutrinos by radio-frequency (RF) signals resulting from neutrino interactions in-ice have intensified over the last decade. Recent calculations indicate that one may
Bulk and Surface Radio-Frequency Response of Ice
The flux and cross section of high energy neutrinos is an active area of research. Due to the expected low flux and cross section, interactions are rare and direct detection is ruled out. Large
The simulation of the sensitivity of the Antarctic Impulsive Transient Antenna (ANITA) to Askaryan radiation from cosmogenic neutrinos interacting in the Antarctic Ice
A Monte Carlo simulation program for the radio detection of Ultra High Energy (UHE) neutrino interactions in the Antarctic ice as viewed by the Antarctic Impulsive Transient Antenna (ANITA) is


South Polar in situ radio-frequency ice attenuation
Abstract We have determined the in situ electric field attenuation length Lα (defined as the length over which the signal amplitude diminishes by a factor 1/e) for radio-frequency signals broadcast
Radio-frequency attenuation beneath Siple Dome,West Antarctica, from wide-angle and profiling radar observations
Abstract Knowledge of the spatial distribution of bed lubrication regimes, i.e. frozen vs wet conditions, is crucial for understanding ice-sheet flow. Radar sounding can probe differing
Modeling Englacial Radar Attenuation at Siple Dome, West Antarctica, Using Ice Chemistry and Temperature Data
[1] The radar reflectivity of an ice-sheet bed is a primary measurement for discriminating between thawed and frozen beds. Uncertainty in englacial radar attenuation and its spatial variation
Deep Ice Stratigraphy and Basal Conditions in Central West Antarctica Revealed by Coherent Radar
Radar-detected layer stratigraphy does not show evidence of flow-induced disturbances that might complicate the depth-age relationship and the interpretation of climate history preserved in the ice, and bed reflectivity over the region varies by more than 30 dB.
Measurements beneath an Antarctic ice shelf using an autonomous underwater vehicle
The cavities beneath Antarctic ice shelves are among the least studied regions of the World Ocean, yet they are sites of globally important water mass transformations. Here we report results from a
Crystal orientation fabrics within the Antarctic ice sheet revealed by a multipolarization plane and dual-frequency radar survey
[1] To investigate the viscosity structure of ice sheets induced by crystal orientation fabric (COF), we carried out a multipolarization plane and dual-frequency radar survey in East Antarctica.
Investigations of the form and flow of ice sheets and glaciers using radio-echo sounding
Radio-echo sounding (RES), utilizing a variety of radio frequencies, was developed to allow glaciologists to measure the thickness of ice sheets and glaciers. We review the nature of electromagnetic
