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

, 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

Optimising ice flow law parameters using borehole deformation measurements and numerical modelling

Geophysical Research Letters, 2008
Internal ice strain rates have been measured along two boreholes drilled through Glacier de Tsanfleuron, Switzerland. Differences between these measurements and the output from a 3D numerical model of glacier motion have been minimized by a scheme that ...

Modelling PolSAR Scattering Signatures at Long Wavelengths of Glacier Ice Volumes

, 2012
The crucial role of cryosphere for understanding the global climate change has been widely recognized in recent decades [1]. Glaciers and ice sheets are the main components of the cryosphere and constitute the basic reservoir of fresh water for high ...

Monitoring ice-capped active Volćan Villarrica, southern Chile, using terrestrial photography combined with automatic weather stations and global positioning systems

, 2008
Volc´an Villarrica (39◦25'12" S, 71◦56'27"W; 2847ma.s.l.) is an active ice-capped volcano located in the Chilean lake district. The surface energy balance and glacier frontal variations have been monitored for several years, using automatic weather ...

Minimal Glacier Models

, 2008
During the past few decades the study of glaciers and their response to climate change has shown a strong development. Early theoretical work in the fifties and sixties has been complemented by the construction of numerical models of glaciers and ice sheets with various degrees of complexity.

Comparison of remote sensing derived glacier facies maps with distributed mass balance modelling at Engabreen, northern Norway

, 2007
Calibration and validation of glacier mass balance models typically rely on mass balance data derived from measurements at individual points, often along altitudinal gradients, thus neglecting much of the spatial variability of mass balance.

Sensitivity of a distributed temperature-radiation index melt model based on AWS observations and surface energy balance fluxes, Hurd Peninsula glaciers, Livingston Island, Antarctica

, 2012
We use an automatic weather station and surface mass balance dataset spanning four melt seasons collected on Hurd Peninsula Glaciers, South Shetland Islands, to investigate the point surface energy balance, to determine the absolute and relative ...

Advances in modelling of valley glaciers

, 2012
For glaciological conditions typical of valley glaciers, the central idea of this research lies in understanding the effects of high-order mechanics and parameterizing these for simpler dynamical and statistical methods in glaciology. As an effective tool for this, I formulate a new brand of dynamical models that describes distinct physical processes ...

Mass-balance modelling of Gangotri glacier

, 2017
The sensitivity of glacier mass balance (MB) in response to climatic perturbations has made it an important parameter of study from hydrological, climatological and glaciological point of view.
