Effect of carbonate ion concentration and irradiance on calcification in planktonic foraminifera
The effect of carbonate ion concentration ([CO2−3])on alcification 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 levels (35 and 335 μmol pho...
