Michael Apparently No Help In Removing Red Tide From Florida's Gulf Coast - Wunderground
EDIT
No help to red tide: Hurricane Michael failed to break up a patchy and toxic algae bloom that has lingered in the Gulf off Florida's coast for the last year, experts said Monday, meaning the red tide outbreak could continue to cause problems in the weeks ahead. Hurricanes can break up algae blooms, but they also drop fresh water and increase nutrient-rich runoff from land, which can make them worse, said Robert Weisberg, a professor of physical oceanography at the University of South Florida. Michael blew red tide at the water's surface into shore, but deep ocean currents that have been feeding the bloom since the summer also have persisted, he said. "The factors that contributed to red tide outweighed the ones that would reduce it," Weisberg said.
