Fig. 2: Characteristics of the summer/fall 2020 marine heatwaves.
From: The severe 2020 coral bleaching event in the tropical Atlantic linked to marine heatwaves
Mean marine heatwave cumulative intensity (shading; in °C-day) for: a December 2019, b January 2020, c February 2020, d March 2020, e April 2020, f May 2020. g Time series of observed SST (thick line), the long-term climatology (dotted line) and the 90th percentile climatology (dashed line) at Rio do Fogo reefs (5.2°S and 35.2°W; black star in panel a). Marine heatwave severity categories I–IV are shown in shades of red: I, moderate; II, strong; III, severe; IV, extreme. The grey dotted line represents the maximum monthly mean SST and the grey dashed line represents the bleaching threshold according to the NOAA Coral Bleaching Watch.
