Karenia brevis is a microscopic, single-celled, photosynthetic organism in the genus Karenia. It is a marine dinoflagellate commonly found in the waters of the Gulf of Mexico. [ 1 ] It is the organism responsible for the "Florida red tides " that affect the Gulf coasts of Florida and Texas in the U.S., and nearby coasts of Mexico.
According to Marine Lab at University of Miami, the first possible Red Tide in Florida was in 1844. Earlier "signs" were from boats sorting fish on their way to home port dumping trash fish overboard. Thus "dead fish" reports along the coast were not Red Tide. [213] 1793: The first recorded case occurring in British Columbia, Canada. [214]
Tidal range. Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
South Florida is made up of a lot of low-lying areas near the water, and as the sea rises, king tides will reach farther and farther inland. It overwhelms storm drains, stops traffic routes and ...

In southwestern Florida, the storm produced a storm surge of 1.13 ft (0.34 m) in St. Petersburg. [10] In the central portion of the state, some areas for pasture were flooded due to outer rainbands. [39] The Florida panhandle was still recovering from Hurricane Dennis when Katrina moved ashore.
Rip tide. A rip tide, or riptide, is a strong offshore current that is caused by the tide pulling water through an inlet along a barrier beach, at a lagoon or inland marina where tide water flows steadily out to sea during ebb tide. It is a strong tidal flow of water within estuaries and other enclosed tidal areas.
Another cause of manatee deaths are red tides, a term used for the proliferation, or "blooms", of the microscopic marine algae Karenia brevis. This dinoflagellate produces brevetoxins that can have toxic effects on the central nervous system of animals. [60] In 1996, a red tide was responsible for 151 manatee deaths in Florida. [61]
