摘要
14C plays an important role in the study of ocean circulation and anthropogenic CO2. Radioactive 14Cis usually used in ocean carbon circulation model to test the physical performance of model. In the presentpaper, a 14C model is established and coupled with the IAP/LASG L30T63 global ocean circulation modelto simulate the distribution of natural 14C in oceans and the penetration and uptake of 14C in oceans afterindustrial revolution and nuclear bomb test. The simulation of natural 14C reveals the basic characteristicsof oceanic ventilation. However, simulation value is "younger" than observation in the Pacific and IndianOceans, and "older" than observation in the Atlantic deep ocean. The simulation of bomb 14C agrees wellwith GEOSECS observation, but the volume inventory and averaged penetration depth of bomb 14C inoceans are smaller than observation. The probable reasons for these discrepancies are analyzed.
