Description :
A two-dimensional soil thermal model that accounts for soil unfrozen water and phase change was used to analyse data from the laboratory and a field site in Spitsbergen. A close correspondence was found between modelled and observed thermal behavior of the probe. In most cases the frozen soil thermal properties vary little below about -2°C, and the thermal properties determined for the soil at temperatures approximately below -10°C can be applied to soil at temperatures approximately up to -2°C.
