This project continues observations of an unexpectedly "strong" 1992 El Nino Southern Oscillation (ENSO) event on corals and coral reef ecosystems of the eastern Pacific Ocean. Dr. Glynn is presently completing a 10 year monitoring program on the recovery processes of coral reef ecosystems from previous ENSO events, which were classified as "very strong" and "weak". It now appears as this project is approaching completion, that a "strong" ENSO event is in full swing and that the warming of surface waters is being felt by several coral reef ecosystems in the eastern Pacific region. Based on biological samples (corals) collected early this year from sites off Panama, Costa Rica and the Galapagos Islands, it appears that corals are once again experiencing loss of pigments and zooxanthellae, termed "coral bleaching". The project will obtain real-time responses of coral reef organisms to a "strong" El Nino disturbance, which will be useful for comparison with past "very strong" and "weak" warming events in the eastern Pacific Ocean.

该项目继续观测1992年厄尔尼诺-南方涛动（ENSO）对东太平洋珊瑚和珊瑚礁生态系统的意外“强烈”影响。格林博士目前正在完成一项为期10年的监测计划，该计划是关于从以前的ENSO事件中恢复珊瑚礁生态系统的过程，这些事件被分类为“非常强”和“弱”。现在看来，随着这个项目接近完成，一个“强烈”的ENSO事件正在全面展开，东太平洋地区的几个珊瑚礁生态系统正在感受到地表水的变暖。根据今年早些时候在巴拿马、哥斯达黎加和加拉帕戈斯群岛附近采集的生物样本（珊瑚），珊瑚似乎再次经历了色素和虫黄藻的丧失，被称为“珊瑚白化”。该项目将获得珊瑚礁生物对“强”厄尔尼诺扰动的实时反应，这将有助于与过去东太平洋“非常强”和“弱”变暖事件进行比较。
