The super greenhouse climate of the middle Cretaceous represents an analogue for an extreme CO2 induced (run-away) climate system. In order to improve the understanding of how the high northern latitudes responded to the escalating middle Cretaceous warmth we analysed dinocysts, palynofacies, δ13C and various biomarker proxies through a unique mid Cretaceous succession from the northern Baffin Bay. Our study is based on a several sites that were cored during the IODP Expedition 344S.The composite section represents a nearly complete Albian - Turonian succession deposited during the syn-rift phase separating Greenland from Canada/North America. Depositional environments range from anoxic outer shelf and pro-delta fringe to oxygen-restricted lower delta front. The organic geochemical proxies are focusing on the OAE 2 and will investigate changes in the sea surface temperature and water column oxygenation related with this event. |
