Seawater samples around Taiwan were collected for pH, DIC, TA and fCO2 analyses. Results showed that their distributions closely related to the distribution of different water types. The high DIC and low pH but lower fCO2 values were found in the Shelf Surface Water (SSW) in the northern part of the study area, while the low DIC and TA but higher fCO2 values were found in the Luzon Coastal Current (LCC) in the northern Luzon Strait. The LCC was weak source under the influence of high temperature. Coastal Water (CW) and SSW represented two major sink areas due to the enhanced biological production stimulated by the high nutrient input from coastal and subsurface waters, respectively. Results also showed that high pH and TA but lower fCO2 were found in Kuroshio Surface Water (KSW) and KSW + Luzon Coastal Current (KSW+LCC) in the region off eastern Taiwan. The warm and saline KSW and KSW+LCC were weak sink owing to the elevated TA/DIC ratio, suggesting their CO2 uptake potential were influenced by biological production. The entire northern SCS represented a weak source under the influence of temperature. Finally, seawaters around Taiwan collectively acted as a sink of atmospheric CO2 with a flux of -0.12¡Ó0.43 mmol m-2 day-1 during the study period.
