Export and lateral advection of organic matter within the biological carbon pump ...
The biological carbon pump (BCP) exports organic carbon from the surface to the deep ocean through which it drives the oceanic carbon storage of atmospheric CO2. The majority of this exported carbon is mediated by sinking marine particles, which are mostly formed by primary producers i.e. phytoplank...
