What is the Sensitivity of Ocean Biogeochemistry to the Efficiency of the Biological Carbon Pump?


OCCI Funded Project: 2008


The factors controlling the efficiency with which particulate organic carbon is transferred from surface to depth are still not well understood, and as a result, the biological carbon pump is crudely represented in global models. Here, we propose a three step data analysis and modeling project:

1) to test the sensitivity of a global ocean biogeochemical-ecosystem-circulation model to the representation of the biological pump,

2) to use the new data syntheses to develop and incorporate more mechanistic rules for the  representation of the biological pump in the ocean model, and

3) to test the response of the biological pump to future changes in climate.
