These data were generated from a one-time experiment in support of a coral
ecophysiology manuscript; published in Global Change Biology 2012.

These data were collected to test the hypothesis that the response of corals to temperature and pCO2
is consistent between taxa. Juvenile massive Porites spp. and branches of P. rus from the
back reef of Moorea were incubated for 1 month under combinations of temperature (29.3 °C
and 25.6 °C) and pCO2 (41.6 Pa and 81.5 Pa) at an irradiance of 599 μmol quanta m-2 s-1.
Using microcosms and CO2 gas mixing technology, treatments were created in a partly nested
design (tanks) with two between-plot factors (temperature and pCO2), and one within-plot
factor (taxon); calcification was used as a dependent variable.
A compilation of
studies placed the present results in a broader context and tested the hypothesis that
calcification for individual coral genera is independent of pH, [HCO3-], and [CO32-].
Unlike recent reviews, this analysis was restricted to studies reporting calcification in
units that could be converted to nmol CaCO3 cm-2 h-1.
These data include coral growth, seawater temperature, and salinity,
and seawater carbonate chemistry including total alkalinity, pH, carbon dioxide (pCO2) and saturation state of aragonite (omega).
