Headed to the beach? If you notice some discolored water, it’s likely Trichodesmium, a blue-green algae found in tropical and subtropical waters. It’s part of a patchy bloom that moves with the wind and currents. The strain found in Florida is not known to be harmful to people or marine life. The County is monitoring.
