Red Tide, Karenia brevis September 16th update


East Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Dade County.
 
Northwest Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Okaloosa, Walton, Dixie and Levy counties or offshore of Wakulla and Levy counties.
 
Southwest Coast
Karenia brevis, the Florida red tide organism, was not detected in water samples collected this week alongshore of Pinellas, Hillsborough, Manatee and Collier counties or offshore of Lee County and the Florida Keys (Monroe County). Five samples collected alongshore of Sarasota County (out of 75 total samples) and one sample collected alongshore of Lee County each contained background concentrations of K. brevis. One sample collected alongshore of Charlotte County contained very low concentrations of K. brevis.
 
Samples collected alongshore in Tampa Bay showed no presence of the dinoflagellate Pyrodinium bahamense, suggesting a dissipation of the ongoing bloom first reported in mid-July.
