Continued glaciological investigations with respect to hydropower and ice-climate relationships, at Pâkitsoq, Jakobshavn, West Greenland

Abstract

Hot-water drilling and mass-balance measurements were carried out on the Inland Ice at Pakitsoq north-east of Jakobshavn. Observations of water level fluctuations in the drill holes indicate a high subglacial water pressure close to the ice overburden pressure. Mapping the occurrence of Wisconsinan ice along the ice margin, by sampling of surface ice, was continued and observations were made around an unexpected tapping of an ice dammed lake.
