Ocean, the largest carbon reservoir in the earth surface, plays an important role in the global carbon cycle, which has significant impact on the earth's climate system. Biological pump (BP) and microbial carbon pump (MCP) are two of the most important pathways for the carbon sequestrations, the efficiency of which modulates determined the carbon stock changes in the ocean and atmosphere. This project aims to clarify the ocean carbon sequestration mechanism of carbon process and interpretation of ocean acidification effect on carbon sequestration and storage, establish the marine sedimentary carbon stock changes linked to global change, further analysis in the process of marine ecosystem carbon storage multiscale regulation mechanism. According to the key scientific problem and target, 4 themes "process of carbon fixation carbon storage mechanism - acidification effect - carbon stock changes" were set up around the core scientific question. Three typical ecological system (continental shelf, basin and coral reefs) in the South China Sea with significant differences of biological community structure and carbon library changes were taken as the study sites. Project will be initiated from the modern biogeochemical process, to demonstrate marine ecosystem carbon process and mechanism of carbon storage and its response to ocean acidification at different levels. Combined with different carbon stock changes of sedimentary systems in 2000 years and high-resolution sea water temperature, pH and carbon library records since the industrial revolution, to explore the ocean carbon stock changes to natural changes and human activities in response mechanism, to clarify regulation mechanism of the biological pump and microbial carbon pump.
