Each GCC model differs in the set of assumptions made and therefore concentrates on different effects. For instance, a simple numerical model of the gas exchange at the ocean-atmosphere boundary in the case of wind-driven roughness of the sea at wind speeds of 7 m s 1 makes it possible to formulate, in the global model, a unit to calculate the persistent C02 flux between the water surface and the atmosphere. This can be exemplified by models of the ocean carbonate system described by many authors. Also, there are other models of the C02 cycle in natural systems (Riedo et al., 2000 Zonneveld, 1998).
