- Abstract - Variation of Î ́13C content in coral skeletons shows the influence of metabolic fractionation in aragonite coral. Understanding coral Î ́13C variation can thus be useful to more understand e.g. past bleaching event which is further useful for coral health and conservation. In this study, Î ́13C content in Porites coral from Labuhan Bajau, Simeulue Islands was analyzed. To know the correlation between variation of coral Î ́13C and light intensity, the monthly variation of coral Î ́13C is compared to solar radiation and cloud cover. The result shows that for the period of 2003 to 2008, coral Î ́13C shows it is well correlated (r=0.42 p=0.153) with cloud cover variation in annual mean scale. Meanwhile, in seasonal mean variation, coral Î ́13C is strongly influenced (r=0.85 p
