This paper uses a time-dependent glaciological model to produce numerical reconstructions of the late Weichselian Svalbard-Barents Sea Ice Sheet, taking account of recent geological, biological, and chronostratigraphic evidence of climatic change
sedimentary facies within Svalbard and the Barents Sea.

Visual year-round observations have shown that snow avalanches are driving the formation of rock glaciers near the glacier Larsbreen in central Svalbard. This model appeas consistent with information on the origin and geometry of internal structures
previously derived by indirect geophysical means on this and other rock glaciers in Svalbard, and on rock glaciers elsewhere. Avalanche-nourished rock glaciers are expected to exhibit a regional downwind preferred orientation.

The aim of this paper is to describe the mechanisms of entrainment, transport and release of glaciofluvial sediment at the high arctic valley glacier Marthabreen (Svalbard), and to outline the ice-deformational processes that determine

A long-term approach based on detailed mapping and lichenometry provides additional information concerning talus-foot rock glaciers overstepping raised beaches in Svalbard. Their regional distribution is primarily controlled by the tectonic pattern
Quantification of thermo-erosion in pro-glacial areas - examples from Svalbard

In this paper surface changes are quantified by comparing air-photo derived digital elevation models (DEMs) from 4 selected pro-glacial areas on Svalbard. The main objectives of this study are to quantify the amount of material mobilised due
