Abstract:

Marine sediments from the Vøring Plateau (Norwegian Sea) have been studied for their dinoflagellate cyst (dinocyst) and foraminiferal content in order to reconstruct sea-surface conditions in the eastern Norwegian Sea during Marine Isotope Stage (MIS) 5e. In combination with stable oxygen isotope and ice rafted detritus (IRD) data, the variations in foraminiferal and dinocyst assemblage composition reflect a stepwise transition from the final phase of deglaciation (Termination II) into typical interglacial conditions. This stepwise change is repeated subsequently during the cooling conditions of glacial inception towards MIS 5d. The interval studied is characterized by relatively high abundances of Bitectatodinium tepikiense, in comparison to present-day values in the area, indicating a larger seasonal temperature amplitude with enhanced surface water stratification during MIS 5e. The important occurrence of the warm-temperate dinocyst Spiniferites mirabilis s.l. concurrent with subpolar foraminifers Turborotalita quinqueloba, Globigerina bulloides, and Globigerinita glutinata reveals that most pronounced interglacial marine conditions prevailed in the area just prior to the transition towards MIS 5d. The late stratigraphic position of this phase in the interglacial is verified by comparison with dinocyst data from south of Iceland, manifesting its over-regional implication. Besides the good agreement in dinocyst and foraminiferal assemblage changes, the variations in and between both fossil assemblages also point to the existence of some significant surface water variability in the eastern Norwegian Sea during MIS 5e.
