The NOAA Coral Reef Watch program uses satellite data to provide current reef environmental conditions to quickly identify areas at risk for coral bleaching. Bleaching is the process by which corals lose the symbiotic algae that give them their distinctive colors. If a coral is severely bleached, disease and death become likely. Coral Reef Watch also offers a modeled Outlook that predicts the likelihood of coral bleaching heat stress on a week-by-week basis, up to four months in the future (the typical length of a bleaching season).

Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one of the greatest disturbances to coral reef ecosystems in the Indo-Pacific, affecting not only coral reefs but also the coastal communities which rely on their resources. This research paper documents a test of a new alternative control method based upon acidic injections of cheap, 100% natural products that was carried out in Vanuatu where the presence of COTS has frequently been reported.
The [Allen Coral Atlas](https://allencoralatlas.org/) combines high resolution satellite imagery, machine learning and field data to produce globally consistent benthic and geomorphic maps of the world's coral reefs. The Atlas is funded primarily by [Vulcan Inc.](https://www.vulcan.com) (founded by the late Paul G.
