Fiery oceans. The red flame-like shapes burning in this image are actually indications of very high water (ocean and lake) chlorophyll concentrations. Chlorophyll is a pigment found in plants and algae. You can see the effect of the easterly trade winds which cause massive upwelling of nutrient-rich water off the West coast of Africa. This causes algal blooms which can be detected with the MODIS satellite. This image encompasses all the MODIS imagery for 2017 combined into a median mosaic.
