Abstract
With large encircling mountain ranges, high-altitude glacial cover and a harsh arctic environment, Greenland is one of the most logistically difficult areas in the northern hemisphere to survey by conventional means. Years of effort by the Danish National Survey and Cadastre (KMS) have produced good quality gravity surveys of some coastal areas (e.g. Forsberg, 1986). On the other hand, except for a few isolated lines and small areal surveys, gravity data is almost totally lacking over the interior of Greenland. Satellite altimetry from SEASAT and GEOSAT provided topographic data over much of the interior of the island south of 72° N (Bindschadler et al., 1989) and this should be extended to the northern interior by ERS-1. However, to be useful for studies of the time variation of the glacial ice mass and climatic studies, altimeter biases and other errors in the satellite data must be established from extensive ground-truth data.
