SOUTHWEST COAST
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Manatee, Charlotte and Lee counties or offshore of Lee County. One sample collected offshore of Pinellas County and one sample collected offshore of Sarasota County contained background concentrations of K. brevis. Two samples (out of 27 total samples) collected alongshore of Sarasota County also contained background concentrations of K. brevis.
Samples collected alongshore of Collier County contained concentrations of K. brevis ranging from not present to very low. Two samples collected offshore of Collier County contained concentrations of K. brevis ranging from present to low. Samples collected offshore of the lower Florida Keys (Monroe County) contained concentrations of K. brevis ranging from not present to medium.
Bloom Boundary (alongshore): A patchy bloom of Karenia brevis has been detected this week alongshore and offshore of Collier County ranging in concentrations from not present to low. A localized bloom of K. brevis has also been detected offshore of Monroe County, on the northern side of the lower Florida Keys, with concentrations ranging from not present to medium.

The University of South Florida's College of Marine Science Center for Prediction of Red Tides (http://cprweb.marine.usf.edu) uses coupled biophysical 3-D models to track and predict harmful algal blooms in the southeastern United States. Various experimental products include Karenia flag maps of bloom locations (http://cprweb.marine.usf.edu/products/karenia-satellite-flags) , 3.5 day HAB trajectory forecasts along with nowcasts, which are reports of current conditions, and forecast models (http://cprweb.marine.usf.edu/models).
