Harmful Algal Bloom Forecasts

Southwest Florida Satellite Imagery


The default base layer in the map below displays an 8-day composite of Chlorophyll Fluorescence products up to 07-19-2024 showing location of algae bloom which may include algae besides Karenia brevis. Another layer may be toggled on to show a Chla anomaly product (07-18-2024) that highlights increased chlorophyll (new blooms) over the past two months.
Water samples from 07-12-2024 to 07-19-2024 found Karenia brevis was either not present or at background levels so there is no risk of respiratory irritation and blooms in imagery are unlikely to be Karenia brevis.


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.
