Within this polar project of our team, spanning the period 2002-2005, we added a thermal submodel to the available three-dimensional model of glacier dynamics and we optimised the time discretization using semilagrangian methods. The main applications focused on Aldegondabreen, Spitsbergen (3D thermomechanical steady-state model) and the ice divide of Roosevelt Island, Ross Ice Shelf, west Antarctica (2D thermomechanical time-dependent model). We also developed a new ground-penetrating radar (VIRL6), with transmitter-receiver synchronisation by optic fibre link. This GPR was used for fieldwork on Hansbreen, Spitsbergen (summer 2003 and spring 2004), Johnsons-Hurd and Bowles, Livingston Island (austral summers 2003-2004 and 2004-2005), Amundsenisen, Spitsbergen (spring 2004) and Fridtjovbreen, Spitsbergen (summer 2005). In December 2004 we deployed a new local net of poles for strain measurements on Hurd glacier, Livingston Island.
