Within this polar project, spanning the period 2006-2008, we added a calving submodel to the available three-dimensional model of glacier dynamics and we optimised the treatment of basal sliding within the model. These improvements were applied to develop a 3D model of the steady-state dynamics of Johnsons glacier (Livingston Island, Antarctica). Additionally, the 2D thermomechanical model transient model was applied to characterize the ice dynamics of several ice divide regions of Antarctica. New versions (VIRL7) of transmitter, receiver and antennae of ground-penetrating radar were developed. In Svalbard, high Arctic, on Amundsenisen and Hansbreen (spring 2006) and Ariebreen and Hansbreen (summer 2006), all of them in Spitsbergen, and on Austfonna ice cap, in Nordaustlandet (spring 2008). In December 2006 we deployed, in collaboration with the National Meteorological Institute (INM, now AEMET), a new automatic weather station on Johnsons glacier. Its data will be used to feed models of melting at the glacier surface.
