AI and satellite data could give Florida earlier warnings of toxic red tides
Red tide, a harmful algal bloom that produces toxins, is known for causing respiratory irritation in humans and killing fish in coastal waters. Recent research shows that the conversation is also shifting to include a more subtle neurological threat.
Red tide, a harmful algal bloom producing toxins, can cause respiratory irritation and neurological symptoms in humans. Florida State University's Bingqing Liu, a satellite oceanographer, uses AI and NASA satellite data to monitor red tides in the Gulf. Liu's research, published in Scientific Reports, reveals how extreme weather events like Hurricane Milton can rapidly intensify Karenia brevis red tides by increasing nutrients in coastal waters through heavy rainfall and runoff.
The study highlights the importance of hyperspectral satellite technology, such as NASA's PACE satellite, which can map and differentiate Karenia brevis from other algal groups, enabling earlier and more precise detection of bloom development over large areas. Combining hyperspectral observations with AI and ocean models allows scientists to forecast red tide events, providing advance notice to vulnerable individuals and allowing for timely advisories and mitigation efforts.
