| 摘要 | In this work, we examined the carbonate parameters, i.e. total alkalinity (TA), pH, and partial pressure of CO2 (pCO(2)), and the air-sea CO2 flux (FCO2) in the continental shelves of the southern Yellow Sea (SYS) and East China Sea (ECS), based on two field surveys conducted in April and August of 2011. Surface pCO(2) showed significant spatial variations, ranging from 246 to 686 A mu atm in spring (average +/- standard deviation = 379 +/- 95 A mu atm) and from 178 to 680 A mu atm in summer (384 +/- 114 A mu atm). During the spring cruise, the central SYS (pCO(2) < 240 A mu atm) and the Changjiang estuary (pCO(2) < 300 A mu atm) were under-saturated with CO2, while the southern SYS and the southwestern ECS were supersaturated (pCO(2) = 420-680 A mu atm). In summer, however, the CO2-supersaturated waters (pCO(2) = 380-680 A mu atm) occupied a relatively wide area, including the nearshore of the SYS and the Changjiang estuary, whereas pCO(2)-deficient water (pCO(2) = 220-380 A mu atm) was observed only at the offshore ECS. In general, the entire SYS and ECS area behaved as a sustained CO2 sink, with average FCO2 of -3.9 and -2.1 mmol m(-2) d(-1) in spring and summer, respectively. Phytoplankton production was the driving force for CO2 absorption, especially during the spring cruise. In addition, we found that typical water mixing processes and decomposition of terrestrial material were responsible for the release of CO2 in three turbidity maximum regions. |
