Future high-mountain hydrology: a new parameterization of glacier retreat [PDF]

Hydrology and Earth System Sciences, 2010
Global warming is expected to significantly affect the runoff regime of mountainous catchments. Simple methods for calculating future glacier change in hydrological models are required in order to reliably assess economic impacts of changes in the water ...

Inferring time-dependent calving dynamics at Helheim Glacier

Journal of Glaciology, 2023
We perform Bayesian inference of the parameters of a time-dependent model of ice flow and calving at Helheim Glacier, East Greenland. We find that, while a time-independent calving parameterization can recover the mean observed terminus position, such a ...

Identification of glacial meltwater runoff in a karstic environment and its implication for present and future water availability [PDF]

Hydrology and Earth System Sciences, 2013
Glaciers all over the world are expected to continue to retreat due to the global warming throughout the 21st century. Consequently, future seasonal water availability might become scarce once glacier areas have declined below a certain threshold ...

Numerical modeling of ice detachment tipping processes: insights from the Sedongpu Glacier, southeastern Tibetan Plateau [PDF]

The Cryosphere
Glacier detachment is a severe natural hazard that can cause enormous damage in downstream regions. During detachment, a glacier will experience an abrupt change from slow-moving to high-speed flow within minutes.

Monitoring glacier flow in Ny-Ålesund with a high temporal resolution ground-based interferometric-phased array radar

Polar Research, 2019
Monitoring glacier flow speed and calving rates is of interest for climate research, global sea-level studies and Arctic ship traffic. The research station in Ny-Ålesund, Svalbard, offers a unique location close to multiple glacier fronts. In this study,

A Bayesian ice thickness estimation model for large-scale applications

Journal of Glaciology, 2020
Accurate estimations of ice thickness and volume are indispensable for ice flow modelling, hydrological forecasts and sea-level rise projections. We present a new ice thickness estimation model based on a mass-conserving forward model and a Bayesian ...

Basal Settings Control Fast Ice Flow in the Recovery/Slessor/Bailey Region, East Antarctica

Geophysical Research Letters, 2018
The region of Recovery Glacier, Slessor Glacier, and Bailey Ice Stream, East Antarctica, has remained poorly explored, despite representing the largest potential contributor to future global sea level rise on a centennial to millennial time scale.

Flow and structure in a dendritic glacier with bedrock steps

Journal of Glaciology, 2017
We analyse ice flow and structural glaciology of Shackleton Glacier, a dendritic glacier with multiple icefalls in the Canadian Rockies. A major tributary-trunk junction allows us to investigate the potential of tributaries to alter trunk flow and ...

The Causes of Debris-Covered Glacier Thinning: Evidence for the Importance of Ice Dynamics From Kennicott Glacier, Alaska

Frontiers in Earth Science, 2021
The cause of debris-covered glacier thinning remains controversial. One hypothesis asserts that melt hotspots (ice cliffs, ponds, or thin debris) increase thinning, while the other posits that declining ice flow leads to dynamic thinning under thick ...
