Reduced calcification and lack of acclimatization by coral colonies growing in areas of persistent natural acidification.
As the surface ocean equilibrates with rising atmospheric CO2, the pH of surface seawater is decreasing with potentially negative impacts on coral calcification. A critical question is whether corals will be able to adapt or acclimate to these changes in seawater chemistry. We use high precision CT...
