Title: BGC-Argo Observations and Ecosystem Forecasting for the Western Pacific Ocean
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 Northwest Pacific Ocean, there are several BGC-Argo floats deployed during the last two years. In this talk, I will show examples of using BGC-Argo floats and coupled physical-biogeochemical models to investigate how ocean circulation affect biogeochemical processes and distributions in the water column.
To investigate how marine ecosystem responses to both natural climate variability and anthropogenic forcing, we also have developed a series of high-resolution coupled physical-biogeochemical models to investigate interaction and exchange processes between Northwest Pacific Ocean and China Seas (East China Sea and South China Sea). I will present some our model results related to nutrient sources and transports and how these processes may affect phytoplankton productivity and carbon cycle in Northwest Pacific Ocean and China Seas.
