Normalized annual records (1917–2020) of (a) linear extension rate, (b) skeletal density, and (c) calcification rate for coral cores collected in Corps de Garde (CG01-03), Caye d’Olbian (CO01-03), Jardin Tropical (JT01-02), and Pointe Borgnèse (PB01-04). The coloured lines represent individual core records, the black bold lines represent the master chronology, and the envelopes represent the associated standard error. Vertical dashed red lines highlight the timings of significant regime shifts in the mean values. (d) The bar chart in the bottom panel shows the number of coral cores available. The period from 1950 to 2020 encompasses the timeframe used to explore growth responses to variations in environmental conditions.
