| Research Abstract |
We compared the observational and model simulation results of the bomb-produced radiocarbon and anthropogenic carbon in the ocean. The model simulation results agree well with the observational ones qualitatively. However the ocean model overestimates or underestimates the bomb radiocarbon in some regions. This implies that the CO2 gas exchange at sea surface and thermocline circulation in the ocean model could be improved.
