Deep Atlantic's role in millennial atmospheric CO2 changes

This project aims to fill in a critical knowledge gap in global carbon cycle research, by generating the first high-resolution deep Atlantic carbonate ion and nutrient records for the last 150,000 years. A novel approach will be used to derive air-sea CO2 exchange signals, which permit straightforward evaluation of the deep Atlantics role in millennial atmospheric CO2 changes under various climate conditions. The intended outcome of this project is to substantially improve our understanding of the mechanisms that govern the global carbon cycle. This should provide significant benefits including the assessment of models used to predict future global warming due to anthropogenic CO2.
