Increases in ocean temperature and changes to ocean chemistry are causing widespread coral bleaching, more frequent disease, and reduced coral growth rates. Key indicators used to identify and monitor environmental trends are listed below.
Data collection methods include moored oceanographic and ecological instruments stationed at fixed points in the Atlantic and Pacific Oceans, water samples collected by divers, and satellite-based observations.
These extensive monitoring data provide a comprehensive view of environmental impacts on coral reef ecosystems and help identify areas of resilience and vulnerability. The data are also used in modeling efforts.
NCRMP monitors in the Atlantic, Caribbean, and Gulf of America on a two year cycle. Typically Florida and the Flower Garden banks are monitored in even years, and Puerto Rico and the U.S. Virgin Islands are monitored in odd years.
NCRMP monitors in the Pacific Islands on a three year cycle. Typically Hawaii and the Northwest Hawaiian Islands in year one, Guam and the Commonwealth of the Northern Mariana Islands in year two, and American Samoa and the Pacific Remote Islands Area in year three.
