The overall effect on net carbon balance on aquatic ecosystem by calcification is complex and not completely understood - and in the Everglades - the effect of carbonate precipitation on the total CO2 balance is completely unknown. The first question that I wish to answer is if a periphyton-dominated Everglades marsh is a source or a sink for carbon dioxide. Furthermore, I wish to determine how the productivity varies between short and long hydro-period marshes as well as how the periphyton contribution to the carbon dioxide sink compares to the contribution of aquatic macrophytes.
