FLORIDA (Reuters) - Scientists in Florida are on the cusp of developing promising methods to control toxic algae blooms like the “red tide” that has been killing marine life along a 150-mile (240-km) stretch of the Gulf Coast, the head of a leading marine lab said . Michael Crosby, president and chief executive of the Mote Marine Laboratory in Sarasota, welcomed a red tide emergency order issued this week by Governor Rick Scott, designating more state money for research, cleanup and wildlife rescues. Interest in mitigation technologies has been heightened by a 10-month-long toxic algae bloom off Florida’s southwestern coast that has caused mounds of rotting fish to wash up on beaches from Tampa to Naples. The red tide also has been implicated in at least 266 sea turtle strandings and is suspected or determined to have caused 68 manatee deaths so far this year, according to Florida Fish and Wildlife Conservation Commission figures. In hopes of combating future outbreaks, scientists are field testing a patented process that would pump red-algae-tainted seawater into an ozone-treatment system and then pump the purified water back into the affected canal, cove or inlet, Crosby said. Experiments carried out in huge 25,000-gallon tanks succeeded in removing all traces of the algae and its toxins, with the water chemistry reverting to normal within 24 hours, he said. Scientists also are studying the possible use of naturally produced compounds from seaweed, parasitic algae and filter-feeding organisms that could be introduced to fight red tides.
