SUBPROJECT - A7
Unraveling the Onset and Spread of Cretaceous Anoxia
We investigated the onset and spread of Cretaceous oceanic anoxic events (OAEs). We reconstructed timing, succession of events and feedback mechanisms such as continental weathering and nutrient release by ocean anoxia at the onset of the two most pronounced Cretaceous OAEs. Additionally, we used climate and biogeochemical ocean models to explore the nutrient, carbon and oxygen budgets of the global ocean under different orbital configurations.
