HONOLULU (AP) — Researchers have completed a comprehensive online map of the world’s coral reefs by using more than 2 million satellite images. The Allen Coral Atlas was named after late Microsoft co-founder Paul Allen and will act as a reference for reef conservation, marine planning and coral science as researchers try to save these fragile ecosystems that are being lost to climate change. It is the first global, high-resolution map of its kind. It gives users the ability to see detailed information about local reefs, including different types of submarine structure like sand, rocks, seagrass and, of course, coral. The maps are being used to inform policy decisions about marine protected areas, spatial planning for infrastructure and upcoming coral restoration projects.
