MCR LTER: Coral Reef: Data in support of Edmunds 2012 Global Change Biology, v18 2173-2183

These data were generated from a one-time experiment in support of a coral
ecophysiology manuscript; published in Global Change Biology 2012. Edmunds et al. (2012) Global
Change Biology 18: 2173-2183 doi:10.1111/j.1365-2486.2012.02695.x These data were collected to test the hypothesis that the response of corals to temperature and pCO 2 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 pCO 2 (41.6 Pa and 81.5 Pa) at an irradiance of 599 μmol quanta m -2 s -1 .
Using microcosms and CO 2 gas mixing technology, treatments were created in a partly nested
design (tanks) with two between-plot factors (temperature and pCO 2 ), 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, [HCO 3 - ], and [CO 3 2- ].
Unlike recent reviews, this analysis was restricted to studies reporting calcification in
units that could be converted to nmol CaCO 3 cm -2 h -1 . These data include coral growth, seawater temperature, and salinity,
and seawater carbonate chemistry including total alkalinity, pH, carbon dioxide (pCO 2 ) and saturation state of aragonite (omega).
