Estimating the large-scale biological pump: Do eddies matter?

One factor that limits our capacity to quantify the ocean biological carbon pump is uncertainty associated with the physical injection of particulate (POC) and dissolved (DOC) organic carbon to the ocean interior. It is challenging to integrate the effects of these pumps, which operate at small spatial (<100 km) and temporal (<1 month) scales. Previous […]

A role for tropical nitrogen fixers in glacial CO2 drawdown

Iron fertilization of marine phytoplankton by Aeolian dust is a well-established mechanism for atmospheric carbon dioxide (CO2) drawdown by the ocean. When atmospheric CO2 decreased by 90-100 ppm during previous ice ages, fertilization of iron-limited phytoplankton in the high latitudes was thought to have contributed up to 1/3 (30 ppm) of the total CO2 drawdown. Unfortunately, recent […]
