Benguela Upwelling

The Benguela Current flows along the southwestern African coast. Upwelling of nutrient-rich, deeper water there supports high productivity in the phytoplankton and higher trophic levels.

This Suomi-NPP/VIIRS view of the upwelling zone was collected on April 2, 2017. Note that the color change across a straight line in the top half of the image is not a processing artifact; it results from land use differences across the Angola/Namibia border. Click on the image for a larger version.
