Detailed sedimentological and geochemical analyses were performed on sediments taken from two gravity cores (PS2118-2 and PS2121-4) and one surface sample (PS2121-2) from the eastern Fram Strait at 79°N to get informations about the paleoclimatic and paleoceanographic conditions through the last 35.000 years. The analyses comprise sand/silt/clay distribution, content of ice rafted debris, clay mineralogy, and measurements of carbonate, organic carbon, and nitrogen. The stratigraphy is based on oxygen isotope stages, 14C-dating, and correlation with other sediment cores from the eastern Fram Strait. The sediments from core PS2118-2 represent the time interval from middle isotope stage 3 to recent. The results can be summarized as follows: (1) During isotope stage 3 the Eastspitsbergen Current transports sediment-loaded icebergs in a seasonally open Fram Strait (SPIELHAGEN 1991). Because of a high content of smectite the source of these icebergs probably is Franz Josef Land. At the end of stage 3 HEBBELN ... : Supplement to: Müller, Claudia (1995): Spätquartäre Sedimentationsprozesse in der östlichen Framstrasse.
