Today’s Image of the Day from NASA Earth Observatory features a bloom of Trichodesmium near the Great Barrier Reef off northeast Australia.
Trichodesmium blooms start off with a yellowish-brown color when the bloom is healthy, turn green as it begins to decay, and turn white after the pigments decay.
The cyanobacteria plays an important role in the ocean because it supplies large quantities of nitrogen for marine ecosystems, accounting for about 60 to 80 percent of nitrogen fixation in the ocean.
This image was captured on September 1, 2019 by the Operational Land Imager on Landsat 8.
