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.

Englacial Pore Water Localizes Shear in Temperate Ice Stream Margins [PDF]

, 2019
The margins of fast‐moving ice streams are characterized by steep velocity gradients. Some of these gradients cannot be explained by a temperature‐dependent viscosity alone.

Evaluating Greenland glacial isostatic adjustment corrections using GRACE, altimetry and surface mass balance data

Environmental Research Letters, 2014
Glacial isostatic adjustment (GIA) represents a source of uncertainty for ice sheet mass balance estimates from the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity measurements.

Toward Improved Understanding of Changes in Greenland Outlet Glacier Shear Margin Dynamics in a Warming Climate

Frontiers in Earth Science, 2018
The Greenland Ice Sheet has experienced accelerated mass loss over the last couple decades, in part due to destabilization of marine-terminating outlet glaciers.

Estimation of Supraglacial Dust and Debris Geochemical Composition via Satellite Reflectance and Emissivity

Remote Sensing, 2012
We demonstrate spectral estimation of supraglacial dust, debris, ash and tephra geochemical composition from glaciers and ice fields in Iceland, Nepal, New Zealand and Switzerland.

On ice floe across the Weddell Sea (thirty years since the opening of the first Antarctic drifting station)

Лëд и снег, 2022
The year 2022 marks the 30th anniversary from operation of the Russian-American drifting station in the Antarctic. It was first experience of organizing a research station on sea ice in the South Polar exploration. Russia and the U.S.

A Review of Bayesian Modelling in Glaciology [PDF]

arXiv, 2021
Bayesian methods for modelling and inference are being increasingly used in the cryospheric sciences, and glaciology in particular. Here, we present a review of recent works in glaciology that adopt a Bayesian approach when conducting an analysis. We organise the chapter into three categories: i) Gaussian-Gaussian models, ii) Bayesian hierarchical ...

The K-transect in west Greenland: Automatic weather station data (1993–2016)

Arctic, Antarctic, and Alpine Research, 2018
We present twenty-three years (1993–2016) of automatic weather station (AWS) data, collected along the K-transect near Kangerlussuaq in west Greenland. The transect runs from east to west, roughly perpendicular to the ice sheet edge at about 67° N. The K-

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Response of Marine‐Terminating Glaciers to Forcing: Time Scales, Sensitivities, Instabilities, and Stochastic Dynamics [PDF]

, 2018
Recent observations indicate that many marine‐terminating glaciers in Greenland and Antarctica are currently retreating and thinning, potentially due to long‐term trends in climate forcing.
