Systems Analysis of complex glaciological processes and application to calving of Amery Ice Shelf, East Antarctica [PDF]

, 2017
Calving is a complex process subject to several cooperating atmospheric, oceanographic and glaciological forcings that vary in space and time, and whose relative effects are challenging to separate.

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

The SUBGLACIOR drilling probe: hydraulic considerations

Annals of Glaciology, 2021
Using significant technological breakthroughs and unconventional approaches, the goal of the in situ probing of glacier ice for a better understanding of the orbital response of climate (SUBGLACIOR) project is to advance ice core research by inventing ...

A self-adaptive two-parameter method for characterizing roughness of multi-scale subglacial topography

Journal of Glaciology, 2021
During the last few decades, bed-elevation profiles from radar sounders have been used to quantify bed roughness. Various methods have been employed, such as the ‘two-parameter’ technique that considers vertical and slope irregularities in topography ...

Monitoring of seasonal glacier mass balance over the European Alps using low-resolution optical satellite images [PDF]

, 2016
We explore a new method to retrieve seasonal glacier mass balances (MBs) from low- resolution optical remote sensing. We derive annual winter and summer snow maps of the Alps during 1998–2014 using SPOT/VEGETATION 1 km resolution imagery.

Measurement of snowpack density, grain size, and black carbon concentration using time-domain diffuse optics

Journal of Glaciology
Diffuse optical spectroscopy (DOS) techniques characterize scattering media by examining their optical response to laser illumination. Time-domain DOS methods involve illuminating the medium with a laser pulse and using a fast photodetector to measure ...

A compact lightweight multipurpose ground-penetrating radar for glaciological applications

, 2011
We describe a compact lightweight impulse radar for radio-echo sounding of subsurface structures designed specifically for glaciological applications. The radar operates at frequencies between 10 and 75 MHz.

Greenland surface mass-balance observations from the ice-sheet ablation area and local glaciers [PDF]

, 2016
Glacier surface mass-balance measurements on Greenland started more than a century ago, but no compilation exists of the observations from the ablation area of the ice sheet and local glaciers.

Snow and ice in the desert: reflections from a decade of connecting cryospheric science with communities in the semiarid Chilean Andes

Annals of Glaciology, 2022
Citizen science and related engagement programmes have proliferated in recent years throughout the sciences but have been reasonably limited in the cryospheric sciences.
