Coral Bleaching Percentage in Krueng Raya Waters, Aceh Besar
Keywords:
bleaching index, coral bleaching, coral reefs, climate change, temperature .Abstract
Coral bleaching happened in some district coincidentally that caused by rising of sea surface temperature level through climate change phenomenon. Krueng Raya Water, Aceh Besar district was one of district which affected by its impact. This research explained the percentage of bleaching index in Krueng Raya water on 3 research station which were Lhok Me, Ahmad Rhang Manyang and Inong Balee. On June 2016, the highest bleaching index occurred in Inong Balee station with 55.5% and the lowest bleaching index occured in Ahamd Rhang Manyang with 79.44%. On August 2016, the highest bleaching index occured in Lhok Me station with 94.93% and the lowest bleaching index occured on Ahmad Rhang Manyang station with 28.64%. The result of this resarch indicated that temperature was one of coral bleaching cause. Not only geographical location,but also the composition of coral communities can affect coral bleaching event.
