【 摘 要 】

Climate change has been identified as a stressor to coral reef ecosystem. Last El-Ninõ episode occurred in 2015-2016, leads to worldwide coral bleaching and mortality, including Indonesia. This study attempted to determine the stressor-response of reef-building corals to climate change in the Menjangan Island, Bali. Temperature data logger measurements and remote sensing dataset observing sea surface temperature (SST) and sea surface height (SSH) were used. The logger was deployed at five-meter depth recording hourly temperature during 2017. Monthly anomalies of SST and SSH covering ten years of observation (2007-2017) were calculated for the region. Monitoring of coral in the region was conducted on February, April and August 2017. Our findings indicate that there was evidence of mortality in the site, particularly on the northern reef flat, coinciding with both high positive SST and high negatives SSH anomalies occurred during the El-Ninõ period.
