Satellite chlorophyll-a annual bloom characterization in Northeast Brazil, Western Tropical Atlantic

This research paper analyzes satellite-derived sea surface chlorophyll concentration (SSC) from 2002 to 2012 to characterize the timing and magnitude of annual phytoplankton blooms in the Sergipe-Alagoas Basin in Northeast Brazil.

• Analysis of SSC data from 2002 to 2012 indicates that the maximum surface phytoplankton bloom in the slope and continental shelf areas of the Sergipe-Alagoas Basin occurs in June, with the process beginning in March.
• The annual phytoplankton bloom cycle in this low-latitude tropical region is primarily driven by lower vertical stability of the water column, which allows nutrients from deeper layers to fertilize the mixed layer, as well as wind mixing and water heating/cooling processes.
• While high rainfall during autumn-winter increases continental drainage into the shelf, the potential impact of river inflow in the coastal region is reduced due to the flow regulation of the Sao Francisco River.
