摘要：Indonesia, the world’s largest tropical archipelago, is composed of more than 17,000 islands with a totalcoastline of more than 81,000 km. Coral reefs are found along the coastlines of many islands. Although coralreefs are considered as important ecosystem, the impact of environment such as the increasing of seasurface temperature could bring the reefs under threat. The objective of this study was to forecast stresslevels of coral reefs bleaching using night-time satellite data in Indonesia. The study used 50 km resolutioncomposite images of NOAA-night-time sea surface temperature anomaly and NOAA-coral bleaching alertarea for the period 2007 to 2012. In order to generate correlation between stress levels of coral reefs bleachingand sea surface temperature anomalies, we observed eight selected areas such as Tegal-Central Java Sea,West Bali National Park, Lamalera Sea, Wakatobi National Park, Tolo Bay, Seram Sea, Raja Ampat MarineConservation Park and Kei Islands. The results of the study show that the stress level of coral reef bleachingvaried from year to year. The study suggests that the stress levels of coral reef bleaching may be explainedby sea surface temperature anomalies using the regression equation: Y = 1.1307X + 1.2158.
