A method is presented to analyse the estimates of carbon fluxes in an ecosystem by demanding that (1) the carbon budget of each ecological group should be balanced and that (2) every carbon flux in these balanced budgets should fall within the range of experimentally obtained values. It is shown that the problem of finding an optimal balanced solution is equivalent to the solution of an overdetermined linear system in the Chebyshev norm. The method is illustrated with a small prototype model. Some results are shown of the analysis of a large data set from the Oosterschelde estuary, S.W. Netherlands. The results indicate that the method is powerful in reducing the uncertainties of fluxes. The method proves to be a useful tool both for decreasing the uncertainty of estimated fluxes without additional field work and (by indicating inconsistent or inconclusive data) for directing further research. In particular, consistency is a prerequisite for any simulation modeling effort.
