Investigating the Intra-Annual Dynamics of Kunlun Glacier in the West Kunlun Mountains, China, From Ascending and Descending Sentinel-1 SAR Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Monitoring glacier dynamics is an effective approach for quantifying the response of the glaciers in cold arid mountainous areas to climate change. However, the quantification of short-term flow dynamics of the mountain glaciers in cold-dry climates has ...

A note on the snout

Journal of Glaciology, 2023
The shallow ice approximation for glaciers and ice sheets is a degenerate model in which the ice surface slope at the margin may be infinite. This result is due to the neglect of the otherwise small longitudinal stress terms.

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 ...

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 ...

Fast Glacier Flow

Eos, Transactions American Geophysical Union, 1987
An AGU Chapman Conference on Fast Glacier Flow was held at Whistler Village, Canada, from May 4 to 8, 1986. The timing of the conference seemed particularly propitious because of results of recent observational programs, such as the breakup of the tidewater Columbia Glacier in Alaska, the imbalance of Ice Stream B in Antarctica and the existence of ...

Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]

, 2002
The relationship between the evolution of subglacial drainage system morphology and spatial patterns of glacier surface velocity was investigated using dye tracing experiments and ground surveying throughout the 1995 melt season at Haut Glacier d'Arolla,

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.

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 ...

The role of glacier mice in the invertebrate colonisation of glacial surfaces: the moss balls of the Falljökull, Iceland [PDF]

, 2012
Glacier surfaces have a surprisingly complex ecology. Cryoconite holes contain diverse invertebrate communities while other invertebrates, such as Collembola often graze on algae and windblown dead organic on the glacier surface.

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]

, 2012
We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.
