Surface water pCO2 ranged from 751-2 095 µatm (1 atm=101 325 Pa) in the inner estuary, 177-1 036 µatm in the outer estuary, and 498-1 166 µatm in Hangzhou Bay. Overall, surface pCO2 behaved conservatively during the estuarymixing. In the inner estuary, surface pCO2 was relatively high due to urbanized pollution and a high respiration rate. The lowest pCO2 was observed in the outer estuary, which was apparently induced by a phytoplankton bloom because the dissolved oxygen and chlorophyll a were very high. The Changjiang River Estuary was a significant source of atmospheric CO2 and the degassing fluxes were estimated as 0-230 mmol/(m2·d) [61 mmol/(m2·d) on average] in the inner estuary. In contrast, the outer estuary acted as a CO2 sink.
