The main purpose of this project is to investigate the cycling and air-sea exchange of carbon dioxide (CO2) and related controlling processes in the East China Sea (ECS) and further to examine the role of East China Sea margins in the global carbon cycling. We are planning a comprehensive examination of CO2 in the coast margins using a combining experimental design (i.e, field investigations with a theoretic modeling). The main effort of observational study is devoted to carry out the underway fCO2 measurements in the ECS. The results will be used to derive the air-sea exchange fluxes of CO2, to understand the carbon dynamics of the East China Sea and further to evaluate the controlling mechanisms and impacts of Changjiang runoff and Kuroshio upwelling and atmospheric forcings on the CO2 biogeochemistry of the ECS. Over the long-term observation, we expect to incorporate these multi-media data into a coupled physical-biogeochemical model for the ECS. The results will finally allow to be applicable to other similar coastal environments and to be further served as a decision tool for future environmental policy.東海二氧化碳生地化循環海氣交換通量大陸/海洋邊緣East China Seacarbon dioxidebiogeochemistryair-sea exchange fluxcontinental/ocean margins
