热带珊瑚礁监测在很大程度上依赖于潜水员的现场观察。然而，在许多珊瑚礁地区，没有资源定期监测珊瑚礁。由于缺乏历史基线数据，很难确定不同的珊瑚礁对环境压力的反应以及对管理的影响。为了测试珊瑚芯是否可以用来识别漂白事件的回顾性，在托巴哥与预先存在的珊瑚礁数据，包括水质和漂白observations.Colpophyllianatansores的三个网站进行了检查的生长异常期间发生的热应力。如果存在，将异常与现场实时漂白观察和水质数据进行比较。有趣的是，在2005年热异常期间水质较好的地点不太容易发生漂白。我们建议通过减少陆地径流（例如，珊瑚礁管理人员可以通过减少海洋沉积物和营养物（例如沉积物和营养物），从而改善海洋水质，提高近岸珊瑚礁在高温事件中的复原力。
Tropical coral reef monitoring relies heavily on in situ diver observations. However, in many reef regions resources are not available to regularly monitor reefs. This lack of historical baseline data makes it difficult to determine how different reefs respond to environmental stressors and what the implications are for management. To test whether coral cores could be used to identify bleaching events retrospectively, three sites in Tobago with pre-existing reef data including water quality and bleaching observations were identified.Colpophyllianatanscores were examined for growth anomalies which occurred during periods of thermal stress. If present, anomalies were compared to in situ, real-time bleaching observations and water quality data. Interestingly, sites with better water quality during the 2005 thermal anomaly were less prone to bleaching. We suggest that by reducing terrestrial run-off (e.g., sediment and nutrients), and therefore improving marine water quality, reef managers could enhance near-shore coral reef resilience during high-temperature events.
