Harmful Algal Bloom Forecasts

Southwest Florida Satellite Imagery


Composite 8-days of satellite imagery up to 10-16-2021

showing location of algae bloom which may include algae besides K. brevis. Overlaid cell count data provided by several contributors.

Water samples from 10-09-2021 to 10-16-2021 detected Karenia brevis, red tide, along the coast at levels that pose a respiratory irritation risk in BAY, CHARLOTTE, DIXIE, ESCAMBIA, FRANKLIN, GULF, HILLSBOROUGH, LEE, LEVY, MANATEE, PINELLAS, SARASOTA and WALTON counties and at levels unlikely to cause respiratory irritation in OKALOOSA and TAYLOR counties.


The images were derived from Copernicus Sentinel-3 satellite data from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and were processed by NOAA, National Centers for Coastal Ocean Science. Cell count data were provided by several contributors.
