Effect of carbonate ion concentration and irradiance on calcification in planktonic foraminifera
International audience The effect of carbonate ion concentration ([CO 3 2- ]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa and Globigerinoides sacculifer. Experiments on G. sacculifer were conducted under two irradiance...
