在1987年夏末至秋季期间，加勒比海礁珊瑚经历了一次强烈而广泛的变色事件，被称为漂白。与最初的预测相反，大多数漂白珊瑚并没有死亡。然而，来自虫黄藻的能量输入减少，如从以下估计的：（i）δ 13 C值，骨骼文石在12 C/13 C同化中对13 C的辨别的量度;（ii）原位光合作用-辐照度测量;（iii）Montastraea annularis和Agaricia lamarcki的组织生物量参数。δ 18 O在16 O/18 O同化中的作用，来自M. annularis骨骼表明，这一事件与异常升高的水温相吻合。
During the late summer to fall of 1987, Caribbean reef corals experienced an intense and widespread discoloration event described as bleaching. Contrary to initial predictions, most bleached corals did not die. However, energy input from zooxanthellae decreased, as estimated from: (i) .delta.13C values, a measure of the discrimination against 13C in 12C/13C assimilation, of skeletal aragonite; (ii) in situ photosynthesis-irradiance measurements; (iii) and tissue biomass parameters of Montastraea annularis and Agaricia lamarcki. The .delta.18O in 16O/18O assimilation, from M. annularis skeletons demonstrated that this event coincided with abnormally elevated water temperatures.
