Remote sensing imagery of discolored water and algal blooms in the Florida Bay and the Florida Keys region between 1992 and 2013 showing connectivity of the mainland and the lower Florida Keys, all outlined in red. (a) Landsat true color image on 29 May 1992 shows turbid water in western Florida Bay and discolored, black water in central Florida Bay that extends southward to the lower Florida Keys; (b) AVHRR reflectance image on 12 March 1996 shows high turbidity from the Shark River Slough plume extending beyond the lower Florida Keys towards Dry Tortugas; (c, d) VIIRS chlorophyll a anomaly images show phytoplankton blooms off Shark River Slough reaching the lower Florida Keys that were partially composed of the cyanobacterium, Synechococcus, on (c) 24 November 2013 and (d) 27 January 2014.
