Abstract

An emergence curve for eastern Kongsoya shows that a shoreline displacement of more than 100 m has taken place during the Holocene. The rate of emergence is high, about 4 m/100 years during the first one thousand years and 0.3 m/100 years during the last thousand years. Two levels with high concentrations of pumice have been dated by driftwood samples with ages of 5240 70 years and 3110 80 years. Driftwood seems to have floated ashore throughout most of the Holocene. The about 9000 years old driftwood had an unexpected high percentage of Salix sp. (40 %) and a low percentage of Larix sp. (25 %). The occurrence of American species was also remarkable. The emergence curve presented is the strongest evidence in favour of a Late Weichselian ice sheet over Kong Karls Land.
