Modeling marine ecosystems and their role in ocean biogeochemical cycles has become a growth industry. For example,
fisheries managers want to know whether there will be any fish at the end of the decade; governments want to know if the
oceans will keep accepting excess carbon dioxide until the end of the century and beyond. As scientists we are more
comfortable when using models to integrate observations to obtain a deeper understanding of ecosystem function; but
increasingly we are being asked to predict the future. I will illustrate attempts to address these issues, especially that
of understanding versus prediction, by describing our models of the global ocean carbon cycle and of a recent iron
fertilization experiment in the subarctic NE Pacific.
