Jury et al. (2010)

Calcification rates (as a % change compared with control) were determined for branches of Yellow Pencil Coral (Madracis auretenra) of 3-5 cm in length that were originally obtained from a fringing reef in the Netherlands Antiles. Control conditions included seawater salinity of ~36, temperature of 28°C, irradiance of ~110 µmol photons m-2 s-1, pH = 8.07, TA = 2469 µeq kg-1, DIC = 2101 µmol kg-1, bicarbonate = 1827 µmol kg-1, carbonate = 264 µmol kg-1, and aragonite saturation = 4.22. Experimental Conditions included pH = 8.07, TA = 1515 µeq kg-1, DIC = 1250 µmol kg-1, bicarbonate = 1088 µmol kg-1, carbonate = 157 µmol kg-1, and aragonite saturation = 2.51.
