NASA's Self-Learning AI Maps Harmful Algae from Space
NASA researchers developed a self-supervised AI that fuses data from multiple satellites (including PACE and TROPOMI) to detect and map harmful algal blooms such as Karenia brevis and Pseudo-nitzschia, across Gulf Coast and West Coast waters. The tool helps guide where to sample and warn communities, with plans to expand to additional coastlines and lakes and to make the technology accessible to decision-makers.
