Effect of elevated pCO2 on the boron isotopic composition into the Mediterranean scleractinian coral Cladocora caespitosa

The Intergovernmental Panel on Climate Change (IPCC) predicts atmospheric CO2 partial pressure (pCO2) ranging from 490 to 1,250 ppm in 2100, depending on the socio-economic scenario
considered (Prentice et al., 2001). Because one third of anthropogenic CO2 emissions has been stored in the oceans, ocean pH has already declined by 0.1 unit compared with preindustrial values (Orr et al., 2005) and is predicted to decrease by another 0.4 unit by the end of the century (Caldeira and Wickett, 2003). Seawater acidification will lead to a shift in inorganic carbon equilibria towards higher CO2and lower carbonate ion concentrations.
