"This video podcast highlights 50 years of photographic documentation of coral reefs in the Florida Keys. The photographs show 5 decades of changes that have taken place in both the size and the types of corals that were present at several coral reef sites from the early 1960s to today. The images capture events such as the appearance of coral disease and the die off of coral species like staghorn in the region."
