At the meeting, Director Bai Yan from the Science and Technology Department of the Second Institute of Oceanography, Ministry of Natural Resources, delivered a welcome speech on behalf of the conference organizer. Researcher He Xianqiang, the project principal investigator, reported the overall research progress of the project. Topic principal investigators, namely Researcher He Xianqiang, Professor Qi Di, Researcher Chi Yuan and Researcher Ma Wentao, delivered special reports respectively on the completion of annual tasks, phased research achievements, key research progress and subsequent research priorities. Centering on their respective research tasks, sub-topic leaders conducted in-depth exchanges on a series of research topics, including carbon cycle observation and assessment in the Bohai and Yellow Seas, remote sensing retrieval of net community productivity in the northern South China Sea, controlling processes of the carbonate system in the Yellow and East China Seas, strong carbon sink mechanisms in the East China Sea, anthropogenic carbon dioxide reconstruction, shelf carbon pump of global marginal seas, and the evolution of air-sea CO₂ fluxes in the frontal zone of the Changjiang Estuary and East China Sea.
The participating experts fully acknowledged the phased progress made by the project in the past two years. They commented that the project has been well organized with solid research work and prominent progress, and has achieved fruitful outcomes in multiple key fields, including the stereoscopic observation and dynamic inventory of coastal carbon sinks, regulatory mechanisms of carbon sources and sinks and assessment of anthropogenic carbon variations, division and accounting methods of carbon sink functional areas, as well as simulation and evaluation of carbon sink sustainability and carbon sequestration potential. Meanwhile, the experts put forward valuable suggestions on achievement refinement, strengthening application orientation, and better serving national and industrial management needs. They pointed out that the project should further promote the systematic integration of new equipment, new methods and new cognitive findings, strengthen the connection and achievement coupling among individual research topics, refine representative landmark achievements, and continuously enhance the application support capability and demonstration leading effect of project outcomes in follow-up research.
This meeting comprehensively summarized the annual implementation status and phased research achievements of the project, further clarified the key research directions and core tasks for the next stage, and laid a solid foundation for advancing the high-quality implementation of the project, improving scientific and technological innovation capacity in coastal carbon sink research, and supporting the national “Dual Carbon” strategic demands.
