Harmful algal blooms can have severe consequences for both ecosystems and human populations. In Florida, blooms of Karenia brevis have led to wildlife deaths, beach closures, and respiratory illnesses in humans. On the West Coast, Pseudo-nitzschia blooms have poisoned marine animals, including dolphins and sea lions. These events also disrupt local economies, particularly in tourism and aquaculture. The new AI tool could help mitigate these impacts by providing early detection and enabling targeted responses, reducing the time and resources needed for manual water testing.
