Stadial to interstadial hydrographic changes in the northern Nordic Seas 

New multiproxy records informing in unprecedented detail on hydrographic changes in the northernmost Nordic Seas during Dansgaard-Oechger events, will be presented. An extensive sea ice cover and a homogenous intermediate water mass have been suggested to characterize the Nordic Seas during stadials, based on records from the southern Nordic Seas. Combined planktic and benthic oxygen and carbon isotopes informing on water mass stratification and ventilation, supplemented by planktic Mg/Ca, planktic and benthic foraminiferal abundance, Ice Rafted Debris, diatom, and biomarker data suggests, however, less stable stadial water column conditions in the Fram Strait. The stadial to interstadial transitions are characterized by a series of short living changes in productivity, water mass characteristics and IRD deposition. The new records from the Fran Strait will be see in context of comparable records from other sites in the Nordic Seas. Implications of the new results will be discussed.
