Abstract

The general structure of a three-dimensional model of carbon fluxes in
the ocean is described. Using the computed currents of a realistic model of the general
oceanic circulation, the components which are relevant to the carbon cycle are trans-
ported as dynamically passive properties of the water. As a first step, the transport of
inorganic carbon is simulated, neglecting all biological processes. As boundary con-
dition, chemical equilibrium between the surface of the ocean and the atmosphere is
assumed, no empirical buffer factors or flux rates are used. The computed distributions
of the chemical quantities scent to be realistic within the range of the reflections. The
role of winter convection in high latitudes to the uptake capacity of the ocean for excess
CON in the atmosphere is demonstrated by two extremal assumptions.
