It's the third largest coral reef in the world but it’s the closest to a high-density population that can potentially cause coral disease. But a group of scientists from Miami University and the Florida Aquarium are embarking on a two-day restoration effort to monitor previously transplanted corals. They will also conduct coral disease reconnaissance and plant more than 150 threatened elk-horn corals at a football field-sized coral restoration site in waters off Miami. 
John Zarrella covered the damage that's been inflicted on the Florida reef a few years ago. 
He now goes back to check on the progress of the transplanted coral and the efforts that could help save marine species and protect the state's shores.
