Abstract
Data on calcification rate of coral and crustose coralline algae were used to test the proton flux model of calcification. There was a significant correlation between calcification (G) and the ratio of dissolved inorganic carbon (DIC) to proton concentration ([DIC] : [H
+
] ratio). The ratio is tightly correlated with [CO
3
2−
] and with aragonite saturation state (
Ω
a
). An argument is presented that correlation does not prove cause and effect, and that
Ω
a
and [CO
3
2−
] have no basic physiological meaning on coral reefs other than a correlation with [DIC] : [H
+
] ratio, which is the driver of G.
