Gattuso J.-P., 1996. Productivity and calcification in recent coral reefs: effect on air-sea CO2 fluxes. In: Proceedings of the International Workshop on Response of Coral Reefs to Global Changes, Tsukuba, 4-6 March 1996, pp. 52-63.




Abstract

Coral reefs are major sites of calcium carbonate precipitation and exhibit high rates of organic carbon metabolism. These biological processes are extremely efficient to modify the balance of the inorganic carbon system in seawater. As a result large diurnal changes of the partial pressure of carbon dioxide, which controls air-sea CO2 fluxes, were reported in coral reef waters. This paper provides background information on the processes involved, summarizes recently published information and briefly reviews the present knowledge of community metabolism and associated air-sea CO2 fluxes in coral reef ecosystems.
