How quickly anthropogenic CO 2 is being absorbed by the ocean remains one of the most critical and yet unanswered questions asked by climate researchers. Since the ocean is a major sink of anthropogenic CO 2 ,an accurate estimate of the present oceanic uptake rate of anthropogenic CO 2 is essential for reliable prediction of future atmospheric CO 2 . This number is difficult to pin down because the net airto‐sea CO 2 flux is a small difference (about 2 Pg C yr −1 , 1 Pg = 10 15 g) between two huge fluxes—namely, the uptake and the release of CO 2 at sea surface (each about 90 Pg C yr −1 ).
