From: Growth rates of Florida corals from 1937 to 1996 and their response to climate change

Modelled aragonite saturation state, Ωarag, (left y axis) is presented for the period of the coral growth record (1937–1996) encompassing the study site (24°–25° N and 80°–81° W) along with the calculated percent change in calcification (right y axis) assuming 100% calcification in 1937.
