Chemical bioerosion of C. celata as a function of pCO2 and pH. a CaCO3 dissolved by chemical sponge bioerosion in the baseline experiment normalised for infested oyster surface area and converted into bioerosion rates. b Highly significant positive linear regression of bioerosion rates with increasing pCO2 and decreasing pH levels, respectively. c Highly significant linear regression of the chemical bioerosion expressed as per cent of the respective values in the baseline experiment (independent of normalisation to surface area)
