CARBON DYNAMICS AND METHANE REGULATION IN THE SOUTH CHINA SEA MARGIN: INSIGHTS FROM INTEGRATED GEOCHEMISTRY AND MULTI-PROCESS REACTIVE TRANSPORT MODELING
Seminars
Semester 2
The oceanic carbon cycle plays a dominant role in regulating Earth's climate, with continental margin sediments acting as critical biogeochemical hotspots. While these sediments serve as significant long-term carbon sinks, quantifying their early diagenetic processes remains a fundamental challenge due to the complex interplay of physical, chemical, and biological factors. Traditional frameworks typically simplify the dynamic depositional continuum and benthic-water column interactions, limiting the accuracy of carbon budget assessments in transient environments. To address these uncertainties, this research employs an integrated approach combining geochemical methods with a multi-process reactive transport modeling framework to investigate carbon migration and transformation in the South China Sea margin. The study focuses on characterizing the response of sedimentary biogeochemical systems to transient conditions and constraining the underlying kinetic mechanisms. Ultimately, this work will provide novel mechanistic insights into the coupled processes controlling carbon sequestration and greenhouse gas regulation in this critical marginal sea system.
