A gravity map of Peary Land, North Greenland

Abstract

During the summer af 1978 the Geodetic Institute, Copenhagen, established a regional gravity network as a minor part of the surveying programme, with a combination of barometric, triangulation and doppler-derived heights as vertical control. A preliminary map of bouguer anomalies with 20 mgal contours is shown in fig. 32. Terrain-corrected bouguer anomalies will be avilable at a later stage, when the digital terrain models to be used for plotting height curves on the coming ortho-photo maps are completed. It is important to note that the terrain corrections for some stations in very rugged topography might raise the anomalies considerably, up to the order 10 mgal.
