Abstract
Theuptake of anthropogenic CO2 by theocean in the North Pacific is simulated using a threedimensional
general circulation model (GCM). Atmospheric pCO2 is prescribed for the period
1800 to 1986 to find the uptake bytheocean. The absorption rate of CO2 into the model ocean in
1986 is 0.7 GtC yr^-1 and the uptake in the simulated period is 37 GtC. Those results do not
contradict the previous model and observational studies. The distribution of CO2 in the subpolar
region especially in the Bering Sea is affected by the modelrestoring condition of the temperature
and salinity to theobserved in the marginal seas, although thetotal amount of CO2 accumulated in
themodel ocean is not. Details of thedifference of the distributions of CO2 simulated using the
two circulations derived by the GCMs are discussed.
