The International Ocean Discovery Program’s science plan identifies understanding the response of Earth’s climate system to elevated levels of atmospheric CO2 as one of the key themes for the next phase of scientific ocean drilling. The most recent super-greenhouse interval, from 125-80 Ma in the Cretaceous, provides a unique opportunity to address this theme. This workshop was convened with the specific goal of instigating new oceanic and continental drilling legs designed to further our understanding of Cretaceous oceans, how circulation was driven, the factors that led to ocean acidification and different degrees of deoxygenation, and the impact of these conditions on life at the surface of the ocean and at depth.
