The ocean as part of the global carbon cycle
1994
Wolf-Gladrow, D. (Alfred-Wegener-Institut fuer Polar- und Meeresforschung, Bremerhaven (Germany))
The ocean plays a central role in the global carbon cycle being by far the largest active reservoir. Atmospheric CO2 level depends on the CO2 concentration in the ocean surface layer, which is relatively low compared to mean oceanic values due to biological and physical carbon pumps. Although the ocean may take up much of the carbon released by the increased burning of fossil fuels, this capacity is limited because of the chemical buffering and a mismatch in time scales (oceanic mixing is much slower than anthropogenic perturbations).
