Abstract

The coccolithophore Calcidiscus leptoporus (strain RCC1135) was grown in dilute batch culture at CO2 levels ranging from similar to 200 to similar to 1600 mu atm. Increasing CO2 concentration led to an increased percentage of malformed coccoliths and eventually (at similar to 1500 mu atm CO2) to aggregation of cells. Carbonate chemistry of natural seawater was manipulated in three ways: first, addition of acid; second, addition of a IICO3-/CO32- solution; and third, addition of both acid and IICO3-/CO32- solution. The data set allowed the disentangling of putative effects of the different parameters of the carbonate system. It is concluded that CO2 is the parameter of the carbonate system which causes both aberrant coccolithogenesis and aggregation of cells.
