Coral bleaching has increasingly impacted reefs worldwide over the past four decades. Despite almost 40 years of research into the mechanistic, physiological, ecological, biophysical and climatic drivers of coral bleaching, metrics to allow comparison between ecological observations and experimental simulations still do not exist. Here we describe a novel metric - experimental Degree Heating Week (eDHW) - with which to standardise the persistently variable thermal conditions employed across experimental studies of coral bleaching by modify the widely used Degree Heating Week (DHW) metric used in ecological studies to standardise cumulative heat loading.
在过去的四十年里，珊瑚白化现象在全球范围内对珊瑚礁的影响越来越大。尽管近 40 年来一直在研究珊瑚白化的机制、生理、生态、生物物理和气候驱动因素，但仍然没有可以在生态观测和实验模拟之间进行比较的指标。在这里，我们描述了一种新的指标——实验性加热周（eDHW），用于通过修改广泛用于生态研究的 DHW 指标来标准化珊瑚白化实验研究中使用的持续变化的热条件，以标准化累积热负荷。
