The ground penetrating radar is an excellent tool for snow and glaciers studies, as ice is transparent to the GPR signal. By choosing the appropriate frequency, GPR signal can reach the bedrock of the glaciers, making GPR technology a very promising tool for the measurement of glacier thickness. The detection of snow-covered cracks is also possible, since the transition between the snow and ice can be easily detected due to the changes that occur in the parameters of density, water content and dielectric properties of materials, allowing the clearly identify the ice-snow interface. The field experiences have shown that cracks of around 0.5 m in width can be detected under a layer of snow of several meters.
