This long-term study focuses on the ecological disturbances to eastern Pacific coral reefs that accompanied the severe and historically unprecedented 1982-83 ENSO (El Nino-Southern Oscillation) event. During the first 3-year segment (1985-87) of the study a strong causative link was established between prolonged sea warming and numerous kinds of primary disturbances. During the first and second 3-year (1988-90) study periods the team of workers involved in this study have (a) demonstrated the importance of several secondary (long-term) disturbance processes, (b) revealed the extent of recovery and continuing reef destruction to date, and (c) provided some indication of the frequency of severe El Nino disturbances to coral reefs in an historical context. Because some important secondary disturbances are still occurring, and reef recovery has been slow (Costa Rica, Panama) or non-existent (Galapagos Islands), it is necessary to continue with this study in order to understand the variety of changes involved and the full impact of a major disturbance on coral reef survival and the potential for continued reef building. ENSO warming disturbances can provide some clues to the probable changes in coral reefs worldwide if global warming causes repeated and/or protracted sea temperature increases comparable to the 1982-83 El Nino event.

这项长期研究的重点是生态干扰 东太平洋珊瑚礁，伴随着严重的， 历史上前所未有的1982-83年ENSO（厄尔尼诺-南方 振荡）事件。在第一个三年期（1985-87年）， 研究表明， 长期的海洋变暖和许多种类的原始扰动。 在第一个和第二个3年（1988-90年）研究期间， 参与这项研究的工作人员团队（a）证明了 若干次级（长期）干扰重要性 过程，（B）揭示了恢复和持续的程度 （c）提供了一些关于 严重的厄尔尼诺干扰珊瑚礁的频率， 历史背景。因为一些重要的次要因素 干扰仍在发生，珊瑚礁恢复缓慢 （哥斯达黎加、巴拿马）或根本不存在（加拉帕戈斯群岛），它是 继续进行这项研究，以了解 所涉及的各种变化和一个重大变化的全面影响 对珊瑚礁生存的干扰以及 继续造礁。ENSO变暖扰动可以提供 一些线索，可能的变化，珊瑚礁在世界各地，如果 全球变暖导致反复和/或持久的海水温度 与1982-83年的厄尔尼诺事件相当。
