Researchers used aerial imagery and artificial intelligence for the first time to map coral across the main Hawaiian Islands in a study published in PNAS. From January to February of 2019, scientists with Arizona State University flew an aircraft-based laboratory around each of the main Hawaiian Islands to collect data. This data mapped, within a 2-meter resolution, live coral cover down to about 53 feet (16 meters). They found that nearshore coastal development had a major negative impact on corals due to increased pollution and sedimentation. Click here to learn more.
