Introduction to the Lecture：

The Biogeochemical-Argo (BGC-Argo) Program aims at operating a network of profiling floats equipped with sensors of key biogeochemical variables for supporting research activities that address impacts of changing climate on ocean biogeochemical cycles and ecosystems. In the Western Pacific, a total of 24 BGC-Argo floats have been deployed during the last several years. In this talk, I will show examples of using BGC-Argo floats and coupled physical-biogeochemical models to investigate how synoptical events (typhoons, winter and dust storms) and mesoscale eddies affect upper ocean biogeochemical processes. We also use a coupled physical-biogeochemical model based on ROMS-CoSiNE to address how large-scale climate variability (ENSO and PDO) affect nutrient and plankton dynamics in the Western Pacific Ocean.

Profile of the Speaker:

Chai Fei, who earned his Ph.D. from Duke University, has held positions as an assistant professor, associate professor, and full professor at the University of Maine. He has also served as a researcher at the Second Institute of Oceanography of the Ministry of Natural Resources, director of the State Key Laboratory of Satellite Ocean Environment Dynamics, and an overseas reviewer for the Chinese Academy of Sciences. Currently, he is a member of the Science and Technology Committee for the Earth System Numerical Simulation Device at the Chinese Academy of Sciences, Vice Chairman of the Executive Committee for the 2029 World Ocean Observation Conference (1OceanObs'29) in Qingdao, China, and holds the Tang Shifeng Chair Professorship in Oceanography at Xiamen University. His primary research areas encompass marine science, the ocean carbon cycle, physical-biogeochemical models, marine ecosystems, fishery resources, and BGC-Argo observations.
