Red Tide Status (January 13, 2017)
A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida with patches observed from Pinellas to Sarasota counties.
Over the past week, Karenia brevis was observed in very low to high concentrations in six samples collected from Pinellas County, background to low concentrations in fourteen samples collected from Manatee County, and background to high concentrations in twenty-four samples collected from Sarasota County. Background concentrations were also observed in three samples collected from Charlotte County and seven samples collected from Lee County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Fish kills were reported along Tierra Verde on 1/5 (Pinellas County), Fort Meyers Beach on 1/6 and 1/7 (Lee County), McPherson Bayou (Pinellas County) on 1/10, and Pass-A-Grille (Pinellas County) on 1/12. Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict net offshore transport of surface waters, and southern, onshore movement of subsurface waters between southern Pinellas and northern Monroe counties over the next 3 days.

FWC's Red Tide Action Report
Red tide is a naturally-occurring microscopic alga that has been documented along Florida’s Gulf Coast since the 1840’s and occurs nearly every year. Blooms, or higher-than-normal concentrations, of the Florida red tide alga, Karenia brevis, frequently occur in the Gulf of Mexico. Red tide begins in the Gulf of Mexico 10 to 40 miles offshore and can be transported inshore by winds and currents.
