This project focuses on the mechanisms driving coastal deoxygenation by microbes and their effects on carbon sinks under the multiple stresses of natural change and human disturbance. This project explores the Yangtze estuary, the Bohai Sea and the Yellow Sea, by ship-based observation, field and manipulative experiments, to analyze the processes and mechanisms of coastal deoxygenation from the perspective of microbial control of the marine carbon cycle, to illustrates the impact of marine deoxygenation on carbon sinks through the coupling of carbon, nitrogen and sulfur cycles studies, and to explore the theories and methods for increasing carbon sinks in the deoxygenated environments based on the processes of microbial carbon sequestration and macro-algae carbon fixation. This project will provide insights for the causes of the occurrence and development of coastal deoxygenation, and establish scientific basis and technical support for increasing carbon sink.
