The report presents an investigation of glacio-isostatic conditions in northern and central Greenland, using free-air and Bouguer gravity anomalies. For the north, ice-thickness profiles are calculated from 30-MHz airborne radar propagation data and later combined with British North Greenland Expedition (BNGE) gravity yielding approximate Bouguer anomalies. Gravity and seismic ice-thickness results from the Expedition Glaciologique Internationale au Groenland (EGIG) are used in the Bouguer anomaly calculations for central Greenland. (Author)
