The project was headed by Prof. Zhang Jing. The partners are Yellow Sea Fisheries Research Institute of Chinese Academy of Fishery Sciences, Ocean University of China, the Second Institute of Oceanography of State Oceanic Administration of China, Institute of Oceanology of Chinese Academy of Sciences, and Xiamen University. It comprises 5 sub-projects: 1) biogeochemical process of typical ecological system; 2) response of nutrients cycling to multi-stressors and its feedback; 3) response of physical environment in marginal sea to multi-stressors and its impact on nutrients supply; 4) coupling between microbial food loop and biogeochemical cycle; 5) impact of human activities and climate change on typical ecosystem and the feedback mechanism.
