FIGURE 3.

The sites of modern global coral reef “bright spots” and “dark spots” from 1997 to 2018. Gray dots are the survey sites where the measured percent coral cover was within 1.5 standard deviations (30% total coral cover) of expected coral cover. Yellow dots are the survey sites where the measured percent coral cover was at least 1.5 standard deviations greater than the expected percent coral cover. Dark circles are the survey sites where the observed percent coral cover was less than 1.5 standard deviations less than the expected percent coral cover
