Mass coral bleaching events are one of the main threats to coral reefs. A severe bleaching event impacted Moorea, French Polynesia, between March and July 2002, causing 55+/-14% of colonies to suffer bleaching around the island. However, bleaching varied significantly across coral genera, locations, and as a function of water depth, with a bleaching level as high as 72% at some stations. Corals in deeper water bleached at a higher rate than those in shallow water, and the north coast was more impacted than the west coast. The relatively small scale of variability in bleaching responses probably resulted from the interaction between extrinsic factors, including hydrodynamic condition, and intrinsic factors, such as differential adaptation of the coral/algal association.
大规模珊瑚白化事件是珊瑚礁面临的主要威胁之一。2002年3月至7月期间，一次严重的白化事件影响了法属波利尼西亚的莫雷阿岛，导致该岛周围55±14%的珊瑚群落遭受白化。然而，白化现象在不同珊瑚属、不同地点以及随水深变化显著，一些站点的白化水平高达72%。较深水域的珊瑚白化速率高于浅水区，北海岸受到的影响比西海岸更大。白化反应相对较小的变异性可能是由外在因素（包括水动力条件）和内在因素（如珊瑚/藻类共生体的差异适应）之间的相互作用导致的。
