The need for improved understanding, monitoring, and prediction of coral bleaching has become Even underįavorable conditions, it can take decades for severely bleached reefs to fully recover Corals that are partially to totally bleached for longĮvents have dramatic long-term ecological and social impacts, including loss of reef-buildingĬorals, changes in benthic habitat and, in some cases, changes in fish populations on the reef. Mean temperatures, can cause coral bleaching ( Berkelmans and Willis, 1999 Temperatures as little as 1 to 2 ☌ above a coral's tolerance level, indicated by summer monthly Observed as one of the major causes of mass coral bleaching worldwide. Anomalously warm water temperatures have been ThisĬoral bleaching can be triggered and sustained under variousĮnvironmental stresses. Zooxanthellae, exposing its white calciumĬarbonate skeleton and the affected coral colony becomes stark white or pale in color. Host coral breaks down under certain environmental stresses. Has been one of the most significant contributors to this increasedĬoral bleaching occurs when the symbiotic relationship between algae (zooxanthellae) and their However, in recent decades, coral reef ecosystems have been declining atĪlarming rates worldwide.

Data and images are availableįor free on our website, through the date of retirement of the 50km products.Ĭoral reefs are presently Earth's largest biological structures and have taken thousands of years toįorm. Heritage global data products were produced at 0.5 degree (approximately 50km) spatial Pinpoint areas around the world where corals are at risk for bleaching. NOAA's satellites measure changes in the sea surface temperature (SST), in near real-time, that drive coral bleaching.Ĭoral Reef Watch (CRW) uses this information to SUMMARY: Mass coral bleaching has become one of the most visible marine ecological impacts of persistently rising ocean temperatures.
