Representative values of carbonate system parameters in the three pH treatment culture containers during larval (pre-settlement) and juvenile (post-settlement) growth period.

Samples for the pre-settlement carbonate system data were recorded at the time of larval sample collection for the metamorphosis assay, respiration and filtration rate measurements (the eyespot stage with a well-developed foot or pediveliger stage). Samples for the post-settlement carbonate system data were collected at the end of experiment. The partial pressure of carbon dioxide (pCO2), carbonate ion concentration (CO32−), calcite saturation state (ΩCal) and aragonite saturation state (ΩAg) were calculated using CO2SYS.
