Radio Echo-Sounding of Svalbard Glaciers

Mapping subglacial surfaces of temperate valley glaciers by two-pass migration of a radio-echo sounding survey

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 ...

Mass balance of three Svalbard glaciers reconstructed back to 1948

A simple model using upper-air meteorological variables in the NCEP-NCAR Reanalysis database is used to model seasonal components of mass balance of three glaciers in Svalbard. The model was originally developed for glaciers in North America, and has been applied to glaciers in Norway, Sweden and Iceland. Over the period for which mass balance data are available for the three Svalbard glaciers,...

Photogrammetric methods applied to Svalbard glaciers: accuracies and challenges

Use of digital images is expanding as a tool for glacier monitoring, and smallformat time-lapse cameras are increasingly being used for glacier monitoring of fast-flowing glaciers. Stereoscopic imagery is preferable since it yields direct displacement results but stereo photogrammetry has more requirements regarding geometry in set-up and control points, as well as the additional cost of anothe...
