Surface velocities of a Greenland outlet glacier from high‐resolution visible satellite imagery¹

Abstract

Abstract A multidisciplinary team of researchers reports the results of a study of the feasibility of utilizing high‐resolution Declassified Intelligence Satellite Photographs (D1SP) to derive surface speeds of fast‐moving Greenland outlet glaciers from tracking surface features on sequential DISP images. The images provide coverage of the entire Greenland Ice Sheet for most of the 1960s and their value as a resource for establishing a baseline for assessing ongoing and future changes in the ice sheet is demonstrated.
