Carbon Processes across the Air-Sea Interface

The YS is an important part of the marginal sea in the northwestern part of the Pacific. It was estimated that the ECS and YS could absorb atmospheric CO2 of approximately (13 30)xl0 t C based on Pco2 data calculated from the pH, Aik (alkalinity) and DIG (dissolved inorganic carbon) data observed in the southeast of the ECS. 

1 Horizontal Distributions of Dissolved Inorganic Carbon and Alkalinity in the Surface Water 

The isograms of DIC and Aik of the SML, SSL, and SL are shown in Fig. 3.11 (Gong et al., 2007). The distribution of DIC and Aik in the surface seawater in March is similar to that of May. DIC and Aik decrease in turn from SML, SSL to SL, showing obvious enrichment of DIC and Aik in the SML. The results are consistent with the conclusion that inorganic matter is enriched in the SML near the Nansha Islands of the South China Sea. In addition, there is clearly a positive relationship between DIC and Aik (Fig. 3.12). It could be explained by basic definition formulas of DIC and Aik, in which their main
