Data from: Differential responses to ocean acidification between populations of Balanophyllia elegans corals from high and low upwelling environments
Ocean acidification (OA), the global decrease in surface water pH from absorption of anthropogenic CO2, may put many marine taxa at risk. However, populations that experience extreme localized conditions, and are adapted to these conditions predicted in the global ocean in 2100, may be more tolerant...
