Red Tide Summary (August 29, 2014)
A patchy bloom of Karenia brevis, the Florida red tide organism, has been detected this month in the northeast Gulf of Mexico offshore between Dixie and northern Pinellas counties. In other regions sampled this week along the Florida Gulf coast, only three samples contained background concentrations of K. brevis. No respiratory irritation or fish kills associated with this bloom have been observed alongshore or inshore of the west coast of Florida. Additional samples analyzed throughout Florida this week did not contain red tide.
Satellite images from the Optical Oceanography Laboratory at the University of South Florida show a surface bloom extending between Dixie and northern Pinellas counties, but preliminary data collected this week during an offshore research cruise on the Florida Institute of Oceanography’s R/V Bellows between Levy and Pinellas counties revealed mixed algae blooms often dominated by non-toxic species in surface waters. Low to medium concentrations of K. brevis were found at several locations within this region, mostly in deeper waters. Data from samples collected this week will be available in reports next week, as FWC researchers returned from the cruise earlier today with water samples.
Fish kills and low oxygen in bottom waters have been observed in the offshore bloom area.
Forecasts by the Collaboration for Prediction of Red Tides show slow north movement of surface waters and little movement of bottom waters near the bloom patches in the next few days.
