Fig. 2: Coral bleaching severity and prevalence at Egmont Atoll in November 2019 and March 2020.
From: Mesophotic coral bleaching associated with changes in thermocline depth

a Bleaching severity (bleaching index, BI) and b Bleaching prevalence (percentage, %) at the 2 sites surveyed at Egmont Atoll (Ile Des Rats and Manta Alley) in November 2019 (Nov. 19) and March 2020 (Mar. 20). Different letters = p-values < 0.05 for Kruskal–Wallis tests (see supplementary materials for full details). Each depth band is represented by a different colour and corresponds to a depth zone (shallow water; upper-, mid-, lower-mesophotic zone). The 30–40 m depth band in Manta Alley, Nov.19 was not surveyed due to lack of time and strong currents. The dashed line separates the survey undertaken in November 2019 and March 2020, respectively. The thermometers represent figurative water temperature in mesophotic depths and were adapted from www.flaticon.com.
