Biogeochemical Cycles

We are using ocean models to drive tracer and biogeochemical models to study biogeochemical cycles in the ocean. We are attempting to:

identify and understand the key processes that set the observed distributions and fluxes of carbon and nutrients in the ocean and across the sea surface.
estimate carbon and nutrient fluxes in the ocean and the rates and divergences of relevant bio-geochemical process
use tracers to extract quantitative information about the rates of communication between the surface and the deep ocean.
