Anais do XX Simpósio Brasileiro de Sensoriamento Remoto

We used in situ phytoplankton diagnostic pigments to fit an abundance-based algorithm to retrieve Phytoplankton Size Classes (PSCs) from chlorophyll-a, the in situ validation exercise presented a coefficient of correlation of 0.94-0.63 with a bias varying from 2% to 12%. This regional algorithm was then applied to satellite data (MODIS) to analyze PSC seasonal and spatial variability in the South Brazil Bight (SBB). Our results showed that this method could be an essential tool for understanding the ecological dynamic of the SBB and that the algorithm should be improved further.
