Mean annual calcification rates as a function of average annual sea surface temperature.
In massive Porites spp. from Rib Reef, central Great Barrier Reef Australia (black), Montastraea faveolata from Mahahual (dark blue) and Chinchorro Bank, (red), Mesoamerican Barrier Reef System, M. franksi from Mahahual (orange), and Porites astreoides from Mahahual (light blue) and Chinchorro Bank (purple). CR = calcification rate, SST = sea surface temperature.

Correlation coefficients (CC) for sea surface temperatures (SST) as well as calcification rates for the coral species at the sampled reefs as a function of time (asterisks indicate significant correlations, P<0.05).
Figure 2.
Modeled sea surface temperature and decreasing calcification rates for massive Porites spp. and Montastraea spp. from 1980 to 2100.
(A) Modeled yearly mean sea surface temperature (SST) for the central Great Barrier Reef (purple line) and the Caribbean (black line) from 1980 to 2100. Modeled SST data are from Figures 10C and 8C in [32], respectively. (B) Modeled yearly mean relative calcification rate from 1980 to 2100 for massive Porites spp. (red line) in the Great Barrier Reef and P. astreoides (orange line), and Montastraea spp. (blue line) in the Mesoamerican Barrier Reef System. Yearly mean calcification rate data were generated with the regression lines of the relationship between calcification rate and SST (Figure 1) for massive Porites spp. growing in Rib Reef and P. astreoides, and Montastraea faveolata growing in Chinchorro Bank, using the modeled yearly mean SST presented in figure 2A. Red, orange and blue circles are the historical relative calcification rates of massive Porites spp. in Rib Reef and of P. astreoides, and M. faveolata in Chinchorro Bank, respectively.
