Abstract
Calcification in Corallina pilulifera Postels et Ruprecht displayed di urnal variations in aerated (350 ppm CO2) culture media, with faster r ates during the light than during the dark period. Addition of CO2 (ai r + 1250 ppm) inhibited calcification. This was attributable to the de creased pH resulting from CO2 addition. Both photosynthesis and calcif ication were enhanced in seawater, with elevated dissolved inorganic c arbon concentrations at a constant pH of 8.2.
