Does it seem like your model was based on data from a fairly ideal or well-defined solution? Do you have any plans to incorporate other reactions for Mo that may be relevant in anoxic basins, such as incorporation into organic matter?

Hi Stephan, Excellent presentation but next time how about a Led Zepplin soundtrack? :-) Serious question: the Mo speciation data shown all appear to be model-derived--do you have any actual measurements of Mo speciation in Lake Cadagno? If so, how do they compare with the model output?

Great presentation! I am not familiar with this type of model approach - how would you go about determining the uncertainty in the model output? Could it be that the deviations from real data would still be within model uncertainty? Thanks again.
