Abstract
- In this study, we report the acidification impact mimicking the pre-industrial, the present, and near-future oceans on calcification of two coral species ( Porites australiensis , Isopora palifera ) by using precise p CO 2 control system which can produce acidified seawater under stable p CO 2 values with low variations. In the analyses, we performed Bayesian modeling approaches incorporating the variations of p CO 2 and compared the results between our modeling approach and classical statistical one. The results showed highest calcification rates in pre-industrial p CO 2 level and gradual decreases of calcification in the near-future ocean acidification level, which suggests that ongoing and near-future ocean acidification would negatively impact coral calcification. In addition, it was expected that the variations of parameters of carbon chemistry may affect the inference of the best model on calcification responses to these parameters between Bayesian modeling approach and classical statistical one even under stable p CO 2 values with low variations.
