Radio Echo Sounding of the Greenland Inland Ice

Radio echo sounding has been used for a number of years in the exploration of polar ice such as the inland ice in Greenland and Antarc­ tica. By means of this technique a number of important glaciological and geophysical parameters may be deter­ mined. Examples are ice thickness, bedrock topography and structure, stratification patterns which are used for climate and flow patterns studies, and ice velocity measurements. The technique now constitutes a very im­ portant tool in the investigations of the large polar areas covered by ice. This article describes by way of example the airborne radio echo sounding carried out in Greenland by the Technical University of Denmark (TUD).
