The role of the CaCO3 cycle in climate change.

Project Details


The relative importance of the marine production of carbonates with respect to the global cycle is of carbon involving exchangesbetween the continents, the atmosphere and the oceans is first evaluated on the basis of long term geological time scales. The various chemical processes controlling the behaviour of carbonates in the marine system are then described in terms of equilibrium distances. This approach allows to characterise the chemical state of the carbonate system in sea water and to predict the influence of the biological activity on the distribution of dissolved carbonate species and on the degree of saturation of the system with respect to calcite, aragonite or Mg-calcites.
