Abstract：
Mesoscale eddies are ubiquitous features throughout the world’s oceans that redistribute nutrients (and their ratios) from depth to the euphotic zone, thus inducing a cascade of biochemical and ecological responses (e.g. biomass and phytoplankton composition) that facilitate the downward export of sinking particles (e.g. carbon, nitrogen and silica). Field observations, however, suggest that significant differences in the biogeochemical response occur depending on the mechanism of formation, sampling relative to eddy age, location of sampling within a mesoscale feature, and appropriate non-eddy references. In this talk, I will review the statues of eddy biogeochemistry, and present my own research in the South China Sea and other oligotrophic regions which helps to reconcile such observational bias. Future direction with high spatial-temporal resolution sampling strategy will also be emphasized.
