| 英文摘要 | The distributions of partial pressure of carbon dioxide (p CO2 ) in the surface waters of the Changjiang River Estuary and adjacent Hangzhou Bay were examined in the summer of 2010. Surface water p CO2 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 p CO2 behaved conservatively during the estuary mixing. In the inner estuary, surface p CO2 was relatively high due to urbanized pollution and a high respiration rate. The lowest p CO2 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. |
