Ohde and Hossain (2004)

Calcification rates were measured in Porites lutea corals that were exposed to either normal (~8.2) or reduced (~7.9) pH in the laboratory over a period of 6 hours. Reduced pH conditions were obtained via the addition of HCl into seawater. Temperatures were maintained at 25░C and the light intensity was 11.5 Ámol/m2/s.

Ohde and Hossain (2004)

Calcification rates were measured in Porites lutea corals that were exposed to either normal (~8.2) or reduced (~7.9) pH in the laboratory over a period of 3 hours at night. Reduced pH conditions were obtained via the addition of HCl into seawater. Temperatures were maintained at 25░C and negative values indicate dissolution.
