The proposed study aims at investigating how enhanced CO2 emissions affect the ventilation of the ocean and the biogeochemical turnover of oxygen, nutrients, and carbon. We focus on the Cretaceous period (144 ¿ 65 Ma) when major ocean basins were affected by severe anoxia. By using a suite of time series data from the Tarfaya Basin (Morocco) in combination with numerical models (box modelling, earth system modelling) we will investigate how massive volcanic CO2 emissions at the onset of the Cretaceous Anoxic Event OAE2 triggered large-scale oxygen loss in major ocean basins. The proposed work will close important gaps of previous efforts to disentangle and synthesize proxy records and modelling efforts.
