The absorption of fossil-fuel CO 2 by the ocean
AlI 74 ppm (1 ppm = 1.77 E 14 moles CO2) of anthropogenic CO2 can be accounted for in atmosphere (45 ppm) and ocean (29 ppm) by a simple "diffusive / descending-water" model. 3.8 ppm remain in the mixed layer (at equilibrium), 19.1 have diffused into intermediate waters (at 1.3 cm2 / sec)....
