The results of the 1984-85 post-GISP campaigns in central Greenland are presented. Eight ice cores were obtained, some spanning up to 360 years. We present: I. Geographical positions and elevations at the drill sites, II. Density and temperature in the bore holes, III. Filtered δ 18 O profiles and accumulation-rate variations along the ice cores. The δ 18 O and accumulation profiles, along with those from the 400 m Crête ice core obtained in 1974, are compared. The accumulation-rate series over a large region have a very high coherence. This indicates that a single bore hole in this region would give a representative accumulation time series over a long period. Further, it appears that for this region there is a linear relation between the measured annual accumulation rate and the mean annual δ 18 O values. Thus the area between Crête and Summit, just west of the ice divide, seems to be favorable for a deep-drilling operation.
