A recently released academic study validates what many affected Floridians have long suspected: red tides are correlated to and intensified by human activities. Researchers at the University of Florida, Sanibel-Captiva Conservation Foundation, and Sarasota Bay Estuary Program conducted the study, titled Nitrogen-enriched discharges from a highly managed watershed intensify red tide (Karenia brevis) blooms in southwest Florida.Â
Highlights of the study include:
-
Anthropogenic forcing (human caused environmental effects is a key component of coastal K. brevis bloom dynamics (the organism in red tides that produces a toxin affecting marine life).
-
Caloosahatchee River discharges (which dumps right into the Fort Myers and Sanibel areas) and nitrogen inputs systematically intensify blooms.
-
Anthropogenic influence extends upstream to Lake Okeechobee and the Kissimmee basin.
-
Nutrient/hydrological management may mitigate bloom intensity and duration.
