对珊瑚白化程度的评估已成为旨在了解珊瑚礁状况的研究的一个重要部分。在这项研究中，开发了一种使用珊瑚颜色差异的参考卡，作为评估漂白的廉价，快速和非侵入性方法。该卡使用4种色调内的6点亮度/饱和度标度来记录漂白状态的变化。2个单位或以上的变化反映了共生体密度和叶绿素a含量的变化，因此反映了珊瑚的漂白状态。当使用非专业观察员在外地（这里的潮间带礁坪），有一个观察员间的错误，我的颜色评分。这项技术改进了现有的主观评估漂白状态的目视观察，并提供了快速，大面积的评估不断变化的珊瑚状况的潜力。
Assessment of the extent of coral bleaching has become an important part of studies that aim to understand the condition of coral reefs. In this study a reference card that uses differences in coral colour was developed as an inexpensive, rapid and non-invasive method for the assessment of bleaching. The card uses a 6 point brightness/saturation scale within four colour hues to record changes in bleaching state. Changes on the scale of 2 units or more reflect a change in symbiont density and chlorophyll a content, and therefore the bleaching state of the coral. When used by non-specialist observers in the field (here on an intertidal reef flat), there was an inter-observer error of I colour score. This technique improves on existing subjective assessment of bleaching state by visual observation and offers the potential for rapid, wide-area assessment of changing coral condition.
