热驱动的漂白事件是整个热带地区珊瑚礁生态系统日益关注的问题。为了评估和预测热应力对珊瑚礁的影响，通常使用远程观测的海面温度（SST）;然而，珊瑚礁群落通常延伸到SST本身可能无法准确衡量原地变化的深度。本文利用帕劳附近三个观测站近二十年的温度观测资料（2 - 90 m深度），建立了一个基于SST和海平面异常（SLA）的温度变率随深度变化的经验模型。该技术产生深度平均R2值>0.88，SLA预测温跃层附近的礁前温度，SST捕获上部混合层温度。SLA补充SST提供了一个代理的垂直等温线位移驱动的本地和远程风的季节内到年际的时间尺度。利用这一概念，珊瑚的热应力可以预测从表面通过中光区。
Thermally driven bleaching events are a growing concern for reef ecosystems across the tropics. To assess and predict thermal stress impacts on reefs, remotely observed sea surface temperature (SST) commonly is used; however, reef communities typically extend to depths where SST alone may not be an accurate measure of in situ variability. Here nearly two decades of temperature observations (2‐ to 90‐m depth) at three stations around Palau are used to develop an empirical model of temperature variability versus depth based on SST and sea level anomaly (SLA). The technique yields depth‐averaged R2 values >0.88, with SLA predicting fore reef temperatures near the thermocline and SST capturing upper mixed layer temperatures. SLA complements SST by providing a proxy for vertical isotherm displacements driven by local and remote winds on intraseasonal to interannual time scales. Utilizing this concept, thermal stress on corals can be predicted from the surface through the mesophotic zone.
