At Dome C, a new system, developed at the University of Bern, was used. In brief, a flat surface was prepared along the 2.2 m length of a core using a horizontal band-saw and a milling device. The electrodes assembly consisted of seven electrodes at a spacing of 8 mm across the core. The electrodes were made of a carbon-doped silicon rubber. They were lowered onto the surface of the core, and 350 V was applied across each adjacent pair of electrodes in turn. The current between them was sampled at regular intervals after a settling time, and averaged. The electrodes were lifted and moved l mm along the core before the sequence was repeated. This procedure yielded six sets of data at l mm resolution. The data presented here are given as conductances averaged to l0 mm and corrected to -l5C (Note that the temperature correction of the EDC99 data between 771.7 m and 2201.6 m is only approximative due to problems with the temperature measurement). Documented major core breaks and ends have been removed from the ECM record. There is a slight offset between EDC96 and EDC99 depths (see Parrenin et al.

ABSTRACT SUPPLIED BY ORIGINATOR: As part of the European Project for Ice Coring in Antarctica, a new deep ice core is being drilled at Dome C. Two electrical methods have been used on the core drilled so far: a new design of electrical conductivity method (ECM) instrument, and a traditional dielectric profiler. The two profiles are very similar in both peaks and background, consistent with acidity being the dominant influence on both in this part of the record. The Dome C records have been compared to ECM records from Vostok, and a tentative match has been made between them. This suggests a long-term average ratio of accumulation rate of 1.36 between this Dome C core and Vostok, and that the Dome C core analyzed so far (to 358 m) probably includes the very end of the Glacial-Holocene transition.
