%X The present article brings spatial-temporal analyses at monthly and seasonal time scales from the 15-year time series (2002-2016) of ocean color remote sensing chlorophyll-a images from MODIS/NASA sensor in the Southwestern Atlantic Ocean. Mean and standard deviation of chlorophyll images have shown the distribution patterns already discussed in several works in the study area. On the other hand, analysis of monthly anomaly images showed that the austral winter of 2016 presented the most intense positive anomaly of chlorophyll-a in the last 15 years. Superficial currents data from OSCAR project were used to demonstrate that the austral winter of 2016 was strongly influenced by anomalous strong coastal currents flowing northward. We suggest this was responsible to bring nutrient-rich water from higher latitudes to explain the exceptional increase in phytoplankton biomass on the South Brazilian Continental Shelf during austral winter of 2016 as observed by satellite images.
