Here we report on our studies of chlorophyll-a in the South China Sea (SCS) and its structural features based solely on merged satellite ocean color data (Ocean Color Climate Change Initiative - OC-CCI). The SCS is largely oligotrophic, and its primary production predominantly comes from picophytoplankton. Short-term changes in the SCS picophytoplankton community structure driven by typhoon Wind Pump (WP) are studied against the background of long-term (1998-2016) space-borne OC-CCI observation data. Two ocean color data processing algorithms were applied permitting to reveal (a) the SCS total phytoplankton size structure (in terms of its contribution to chlorophyll-a (chl-a) concentration), and (b) the picophytoplankton community structure. The first algorithm is for partitioning the total chl-a in water into micro-, nano-, and picophytoplankton. The second algorithm quantifies the cell abundances of two species of prokaryotic algae - Prochlorococcus (Pro) and Synechococcous (Syn), and the entire community of eukaryotic picophytoplankton (Peuk) in the SCS...
