AI tool fuses five satellite datasets to help track harmful algal blooms

Phys · · 787 words · By NASA

NASA researchers have developed a self-supervised AI tool that integrates data from five different satellite instruments to detect and map harmful algal blooms. The tool aims to improve the efficiency of monitoring coastal waters in Florida and California, potentially reducing the need for manual water sampling.
