Table 1 Mean (±SD) temperature, salinity, total alkalinity (peq kg− 1), total CO2 (TCO2), partial pressure CO2 (pCO2), bicarbonate (pmol kg− 1), carbonate (pmol kg− 1), pH (pHT = pH on the total scale) and saturation state of aragonite (ΩARAG) for control and high pCO2 seawater treatments across two experiments rearing C.gigas larvae from 2 to 18 h post fertilization

From: Gene expression correlated with delay in shell formation in larval Pacific oysters (Crassostrea gigas) exposed to experimental ocean acidification provides insights into shell formation mechanisms
