Carbon uptake experiments with a zonally-averaged global ocean circulation model ...
A model which simulates the zonally averaged thermohaline circulation in the major ocean basins and includes the balance of stable and decaying tracers, is presented. The model is used to estimate oceanic uptake of tracers due to transiently varying atmospheric concentrations, with steady thermohali...

A model which simulates the zonally averaged thermohaline circulation in the major ocean basins and includes the balance of stable and decaying tracers, is presented. The model is used to estimate oceanic uptake of tracers due to transiently varying atmospheric concentrations, with steady thermohaline circulation. 2 X CO2-experiments with an inorganic carbon cycle component yield an evolution that is consistent with results from 3-dimensional models on time scales of decades to millennia. The model’s average uptake from 1980–1989 is 2.1 Gt C yr-1 when the industrial evolution of pCO2 in the atmosphere is prescribed. Only about 10% of excess carbon is taken up by waters sinking in the North Atlantic but 30% by waters sinking in the Southern Ocean.
