| Summary: | A 181 m deep ice core drilled in 1994/95 on the south dome of Berkner Island, Antarctica, was analyzed for stable isotopes, major ions and microparticle concentrations. Samples for ion chromatography were prepared by using a novel technique of filling decontaminated sample from a device for continuous ice-core melting directly into the sample vials. The core was dated through identification of volcanic horizons and interpolative layer counting. The core, together with a similar core from the north dome, reveals a 1000 year history of relatively stable climate. Temporal variations in the two cores deviate from each other owing to changing patterns of regional-scale circulation; the best correspondence between them is found for MSA-. delta18O, accumulation rate and a sea-salt proxy show only negligible correlation, which suggests a complex meteorological setting. Increasing annual accumulation is observed for the last 100 years. A period of increased sea-salt concentrations started around AD 1405, as has also ... : Supplement to: Ruth, Urs; Wagenbach, Dietmar; Mulvaney, Robert; Oerter, Hans; Graf, Wolfgang; Pulz, H; Littot, Geneviève C (2004): Comprehensive 1000 year climatic history from an intermediate depth ice core from the south dome Berkner Island, Antarctica: methodics, dating, and first results.
