The EMR surveys of previous years (Thorning et al., 1986; Thorning & Hansen, 1987) provided the ice-thickness data necessary for a detailed evaluation of the glaciological-hydrological conditions of the Inland Ice required for planning a hydropower plant at Pâkitsoq (Thomsen et al., 1986). This evaluation also identified some locations where ambiguity in the hydrological interpretation resulted in uncertainties in the estimate of water supply to the Pâkitsoq basin, because the data available did not allow the model to predict the direction of drainage of meltwater. Therefore, further geophysical work was undertaken to provide more detailed information on the subglacial relief of these localities on the ice.
