Abstract: Temperatures within the ice sheets in Antarctica are extremely important for several reasons. Due to the importance of ice temperature, the thermal conductivities of snow and firn were found with the transient line technique at Filchner Ice Shelf. The quick measurements, high spatial resolution, and small probe diameter (1.6mm) were obvious advantages to using this technique. A correlation was found between the apparent thermal conductivities, and the density of snow. Data comparision showed that density alone is a poor measure of snow and firn conductivities and a grain structure is likely the governing parameter of heat transfer.
