Abstract
The influence of total calcium and total carbonate on the growth rate of calcite under seawater-like conditions was studied with a chemostat system. The growth rate increased with increasing calcium concentrati on, due to a higher supersaturation. At equal supersaturation and simi lar free activities of calcium and carbonate, the growth rate increase d at a higher total carbonate concentration. This increase can be expl ained by a contribution of bicarbonate to calcite crystal growth.
