THE IMPACT OF CLIMATE CHANGE AND OCEAN ACIDIFICATION ON THE BIOGEOGRAPHY OF FORAMIFERA
participant Coupled-climate carbon cycle models (C4Ms) are linked to an eco-physiological model to determine the impact of climate-change and ocean acidification on the global 3D distribution of the most abundant foramifera species up until the end of this century. The eco-physiological model is use...
