Abstract: | An evaluation is made of the effectiveness of the ocean's biological pump in driving the deep-sea excess CO2 from the atmosphere. It is based on sediment-trap data available in the literature and on estimates of present and future inputs of anthropogenic nitrogen and phosphorous. The fraction of annual CO2 production from fossil fuel combustion going into this sink turns out to be insignificant in the total budget of man-made CO2. A discussion is presented on the formation of macroflocs under oceanic conditions, a process that has been believed to be important for the effectiveness of the biological pump. |
