Abstract
Glaciological investigations were carried out on the Inland Ice north-east of Jakobshavn. The work is part of the hydropower investigations at Pâkitsoq on a drainage basin proposed for a local hydropower project. The work was started in 1982, when stakes for measuring mass balance were drilled into the ice. So far the investigations have included mass balance measurements, photogrammetric and satellite mapping, ice-thickness mapping, stable isotope studies, simulation of runoff and ice dynamics (Reeh, 1983; Thomsen, 1983, 1984, 1985; Braithwaite & Thomsen, 1984; Thomsen & Braithwaite, 1985; Thomsen & Reeh, 1986; Reeh & Thomsen, 1986a; Thorning et aL, 1986).
Highlights
Glaciological investigations were carried out on the Inland Ice north-east of Jakobshavn
The reconnaissance was confined to areas where large moulins could be seen on recent aerial photographs
To improve the quality of the simulation and thereby provide a baekground for safer eonc!usions about the delineation of the hydrologieal drainage basins on the Inland lee, iee and water samples were eolleeted in the area
Summary
Glaciological investigations were carried out on the Inland Ice north-east of Jakobshavn. 1. The winter snow cover on the ice was very patchy andconfined mainly to drifts in gullies and crevasses up to an elevation about 600 m a.s.l., whereas it was continuous at higher elevations. The transient balance for the winter period was measured in snow pits, and by depth soundings at the stakes. As there were no signs of heavy melting during the winter, the observed distribution of snow cover is probably due to wind drifting. This year's measurements show a higher snow accumulation in the area compared to the previous two years. The 1986 summer ablation is small compared to earlier years This is mainly due to very limited ablation from May to August. The reconnaissance was confined to areas where large moulins could be seen on recent aerial photographs
