- Using results from an earth system model, the distribution of partial pressure of CO2 (pCO2) in surface seawater over the East China Sea is investigated. In this area pCO2 shows minimum along the edge of the continental break along the path of the Taiwan-Tsushima Current System. Apparently modelled chlorophyll is also great along the current but the maximum of the chlorophyll and the minimum of pCO2do not coincide suggesting that the primary production is not the main cause of the pCO2 minimum. As we move toward the Yellow Sea from the Kuroshio area the temperature decreases so that the pCO2 becomes smaller. If we move further toward the Yellow Sea beyond the Taiwan-Tsushima Current System, alkalinity starts to drop substantially to intensify pCO2 while overcoming the effect of decreasing temperature and salinity. Thus pCO2 minimum occurs along the Taiwan-Tsushima Current System. Of course, the primary production lower pCO2 during spring when it is high but the effect is local. Near the Yangtze river mouth and northeastern corner of the Yellow Sea the fresh water input is large enough and dissolved inorganic carbon (DIC) becomes low enough so that pCO2 becomes lower again.
