Coral reefs also protect coastlines by absorbing constant wave energy from the ocean, thereby protecting people living near the coast from increased storm damage, erosion and flooding. Until the 1980’s, the only coral bleaching event recorded was due to flooding from Hurricane Flora that resulted in a large drop in salinity that bleached and killed many corals in Jamaica (Goreau 1964).
