Seawater carbonate chemistry, calcification and Zn uptake during experiments with coral Stylophora pistillata, 2011

DOI

Many studies have investigated the effect of an increase in pCO2 on coral calcification and photosynthesis but the physiological consequences are still relatively speculative. We investigated the effects of ocean acidification on zinc incorporation and gross calcification in the scleractinian coral Stylophora pistillata. Zn is an essential element for health and growth of corals. Colonies were maintained at normal pHT (8.1) and at two low-pH conditions (7.8 and 7.5) during 5 weeks. Corals were exposed to 65Zn dissolved in seawater to assess uptake rates of this element. After 5 weeks, 65Zn activity measured in the whole coral and in the two compartments: tissue and skeleton, differed significantly between pH conditions with concentration factors higher at pHT 8.1, compared to lower pH. Zn is therefore taken less efficiently by corals at reduced pH. Their gross calcification, as measured by 45Ca incorporation, photosynthesis and photosynthetic efficiency did not change with pH even at the lowest level.

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI).
