A MODIS Terra satellite estimate of red tide and Trichodesmium within the western Gulf of Mexico during July–September 2000. Based upon a backscatter algorithm [Cannizzaro et al., 2004], the reddish-black color is a red tide of Karenia brevis and the pale blue color is co-occurring nitrogen fixers at depth, Trichodesmium, within offshore waters (a) on 29 September 2000. The high resolution RGB bands are 470, 555, and 659 nm. The other panels are the satellite estimates of backscatter per unit chlorophyll, on (b) the same day, and earlier on (c) 28 July 2000 and (d) 17 August 2000.
