The reef corals Pocillopora damicornis and Montipora verrucosa were cultured under various controlled temperature and light conditions. The corals were analyzed for growth rate, tissue pigment content and skeletal 13 C and 18 O. Coral skeletal 13 C values varied with light dose and correlated with changes in zooxanthellar pigment. The 13 C values of skeletal aragonite seem to be modified by oxidation of photosynthetically produced organic matter. Functionally significant relationships between coral skeletal 18 O values and temperature have been determined. The temperature coefficients of the 18 O values [-4.4°C (%.) -1 ] are similar to the first order coefficient in the equilibrium paleotemperature equation, but the 18 O values have taxonomically consistent offsets from equilibrium. The offsets may be attributed to the coral metabolism with slight but statistically significant differences between the two genera. Environmental and metabolic variables other than temperature have little or no effect on skeletal 18 O.
