在牙买加愉景湾西前礁6米、12米和18米处建立了永久研究地点。Montastrea annularis、Porites astreodies、Porites porites和Agaricia spp.在1986年10月至1987年9月期间，每隔两个月对漂白组织的存在和程度进行评估。在98%表现出漂白反应的珊瑚中，不到25%的殖民地出现苍白。在剩下的2%中，超过25%的组织出现苍白。M. annularis）、星孢蘑菇（P. astreoides）和伞菌属（Agaricia spp.）显示出显着的正相关性之间的百分比表现出部分漂白反应和海水温度。三种深度之间的菌落漂白百分比没有显著差异。M. annularis和Agaricia spp.表现出比P. astreoides和P. porites显著更高的菌落漂白百分比。支原体annularis 15%的研究珊瑚群显示出1-2平方厘米的随机分散的浅色组织斑块，这些斑块在整个研究过程中保持不变。在这项研究中观察到的部分漂白模式从来没有致命的，被认为是在一定程度上，是对海水温度的季节性变化的反应。
Permanent study sites were established at 6 m, 12 m and 18 m on the West Fore Reef at Discovery Bay, Jamaica. Colonies of Montastrea annularis, Porites astreodies, Porites porites and Agaricia spp. were assessed for presence and extent of bleached tissue at two month intervals between October 1986 and September 1987. In 98% of all corals exhibiting a bleaching response, less than 25% of the colony appeared pale. In the remaining 2%, more than 25% of the tissue appeared pale. M. annularis, P. astreoides and Agaricia spp. showed a significant positive correlation between the percent of colonies exhibiting a partial bleaching response and seawater temperature. There was no significant difference in the percentage of colonies bleached between the three depths. M. annularis and Agaricia spp. exhibited a significantly higher percentage of colonies bleached than P. astreoides and P. porites. For M. annularis 15% of coral colonies studied showed 1-2 cm2 randomly scattered patches of pale tissue which remained constant throughout the study. The partial bleaching patterns observed in this study were never lethal and are considered, in part, to be a response to seasonal variations in seawater temperature.
