Future Telehealth for the Ocean: ‘Reef Halos’ Enable Global Checkups

HIMB researcher Elizabeth Madin is utilizing satellite imagery and AI to monitor coral reef health globally by analyzing "reef halos," which are circular patterns of bare sand created by fish behavior. These halos serve as visible indicators of ecosystem balance, allowing scientists to assess predator-prey dynamics and reef vitality from space without the need for traditional, localized scuba surveys.
