Harmful algal blooms have severe consequences for marine ecosystems, public health, and local economies. In Florida, Karenia brevis kills marine life, degrades beaches, and poses risks to swimmers. On the West Coast, Pseudo-nitzschia blooms have poisoned marine mammals and released airborne toxins that can cause respiratory illnesses in humans. Economically, HABs disrupt tourism, aquaculture, and fisheries, costing U.S. coastal economies tens of millions of dollars annually. The new AI tool offers a faster and more precise method for detecting blooms, potentially reducing these impacts by enabling earlier interventions.
