Reconnaissance GPR survey of the ice caps on islands of Wilhelm Archipelago and on Berthelot island (West Antarctica)
In this paper results of Antarctic ice caps investigations with GPR are represented. Local glaciological investigations of small glaciers on islands at the western coast of the AP are rare. Ice thickness is an important parameter for ice mass balance calculation. Investigation of the layering and in...
