A method for quantitatively comparing calcification rates in coral was used to find an optimum growth temperature for Montipora verrueosa. This method is based on the uptake of the radioactive isotope ca45. By supplying the water the corals are growing i·n with a known amount of radioactivity and comparing this with the activity of the coral samples, a rate of Ca45C03 incorporation can be determined per unit of time.
Various tests show that inorganic exchange does not appear to be a significant factor in interpretation of the results obtained. The edge of a colony calcifies faster than other parts, and the upper surface calcifies faster than the lower. Tests run at various temperatures between 17° C and 34° C indicate that the optimum temperature for calcification is around 30° C.
