| Summary: | Two ultra-high resolution IMAGES sediment cores from the SW continental slope of the Barents Sea and the Vøring Plateau are used to reconstruct fluctuations of a Barents Sea ice sheet with respect to variations in flow intensity and direction of the Norwegian Current during the last glacial-to-interglacial cycle (> 40 - 6.6 14C kyr BP equal to 45 - 7.5 cal. kyr BP). Detailed planktic AMS 14C records from both locations reveal a strong tendency towards higher ages during periods of intense meltwater and/or glacial activity on the Barents shelf.Ages in the core from the continental slope are heavily influenced by reworked 14C-free foraminiferal tests from the Barents shelf. Reworked foraminiferal accumulation rates were quantified by tuning the planktic d18O profile to the GISP2 d18O ice core record. In conjunction with the ice-rafted detritus record, this new proxy shows that ice reached the shelf edge at least twice during the mid-Weichselian and was used to develop a new glaciation curve for the SW ... : Supplement to: Dreger, Derek (1999): Decadal-to-centennial-scale sediment records of ice advance on the Barents shelf and meltwater discharge into the northeastern Norwegian Sea over the last 40 kyr = Dekadische-bis-Jahrhundert-Variabilität von Eisvorstößen auf dem Barentsschelf und Schmelzwasserschüben in die nordöstliche Norwegensee während der letzten 40 ka.
