Processes of crevasse formation and the dynamics of calving glaciers : a study at Breiđamerkurjökull [PDF]

open access: yes, 2009
A new model proposed by Benn et al. (2006, 2007) explains the dynamics of calving glaciers based on a new sliding law and a calving criterion modified from a crevasse depth model. In this thesis three key elements of this model are tested: 1) the role

Flow velocity records at rock glacier Outer Hochebenkar (Äußeres Hochebenkar), 2016

open access: yes, 2021
Surface velocities have been regularly monitored at the rock glacier in Outer Hochebenkar, Ötztal Alps, Austria since the early 1950s. This data collection provides surface velocity time series, showing mean profile velocities of four cross profiles ...

Uncertainty of Satellite-Derived Glacier Flow Velocities in a Temperate Alpine Setting (Juneau Icefield, Alaska)

open access: yesRemote Sensing, 2023
Cross-correlation of image-pairs derived from both optical and synthetic aperture radar satellite imagery is the most common technique for measuring glacier flow velocity and quantifying the dynamics and discharge of glaciers. While the technique has been shown to be effective on polar ice sheets, the accuracy of satellite-derived velocities in ...

Factors controlling the accelerated expansion of Imja Lake, Mount Everest region, Nepal

open access: yesAnnals of Glaciology, 2016
This study explores the link between area increase of Imja Tsho (Lake) and changes of Imja Glacier (area ~25km2) under the influence of climate change using multitemporal satellite imagery and local climate data. Between 1962 and 2013, Imja Lake expanded

Hydraulic impacts of glacier advance over a sediment bed [PDF]

open access: yes, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.
