An englacial hydrologic system of brine within a cold glacier: Blood Falls, McMurdo Dry Valleys, Antarctica

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.

A comparison of contemporaneous airborne altimetry and ice-thickness measurements of Antarctic ice shelves

Journal of Glaciology, 2023
Estimates of ice shelf mass loss are typically based on surface height measurements, assuming hydrostatic equilibrium and estimated firn thickness.

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.

Polarimetric multi-offset radio-echo sounding with a radio frequency-over-fiber ApRES system

Journal of Glaciology
Polarimetric multi-offset radio-echo sounding offers improved constraints on englacial thermal conditions, basal properties and ice crystal orientation compared to standard monostatic observations.

A framework for attenuation method selection evaluated with ice-penetrating radar data at South Pole Lake

Annals of Glaciology, 2020
All radar power interpretations require a correction for attenuative losses. Moreover, radar attenuation is a proxy for ice-column properties, such as temperature and chemistry. Prior studies use either paired thermodynamic and conductivity models or the

Inversion for the density–depth profile of Dome A, East Antarctica, using frequency-modulated continuous wave radar

Journal of Glaciology, 2021
The density–depth relationship of the Antarctic ice sheet is important for establishing a high-precision surface mass balance model and predicting future ice-sheet contributions to global sea levels.

Automated detection and characterization of Antarctic basal units using radar sounding data: demonstration in Institute Ice Stream, West Antarctica

Annals of Glaciology, 2020
Basal units – visibly distinct englacial structures near the ice-bed interface – warrant investigation for a number of reasons. Many are of unknown composition and origin, characteristics that could provide substantial insight into subglacial processes ...
