![]() Over the next two years, the city will test the two locations. The buoys are part of a pilot program funded by the Florida Department of Environmental Protection. The effects on the Hillsborough River will be under a microscope for the next two years. "If it's a moving water body like the Hillsborough River, it's a little bit more problematic because those organisms can escape the influence," he said. However, Rosen said the technology isn't as sound in some bodies of water. "I hear from colleagues that it does work in smaller confined areas where the ultrasound can interfere with the gas vesicles and keep blue-green algae, cyanobacterial, to the lower part of the water column," Rosen said. WFTSS A notice on the Hillsborough River about work being done to take control of blue-green algae.Īlthough new to Tampa, the buoys aren't a new piece of technology, according to Barry Rosen, a professor with the Water School at Florida Gulf Coast University. This is gonna help us keep this and manage it and keep it under control, rather than using an algaecide," Ring said. ![]() That's gonna be the way we're able to control a bloom from taking place. And that'll prevent the algae from growing and proliferating. ![]() "These buoys will project that sound right up to the banks. And it's going to help us maintain the algae growth that we usually see at this time of the year in the river," said John Ring, the City of Tampa Water Production Manager.Įach buoy is capable of producing sound waves within a 500 feet radius to help maintain algae growth common this time of year. Algae sinks to the bottom and die off without releasing toxins. The LG Sonic buoy uses ultrasonic sound waves to block algae's access to sunlight & nutrients. These buoys are equipped with technology to reduce blue-green algae in the water.Īlgae moves to the water surface for photosynthesis to grow and to the bottom of the water column for nutrients. The City of Tampa installed two new buoys Monday, but they're not your average buoys. If you're planning on traveling the Hillsborough River, you may notice a new addition in one part.
