I didn’t really have a chance to get into this too much today, but an important aspect of our work is to use these results to evaluate the ocean carbon cycle GCM models. In general we have found that the models do a reasonable job of reproducing the large scale distributions, but there are a number of regional differences that likely are related to transport issues. For example, here we compare  the data based results with three different versions of the Princeton model. Each of the different versions have different transport and mixing schemes. Jorge will likely talk more about this, but my point here is simply to point out that the carbon data from the global survey can provide a strong constraint for diagnosing the transport in the carbon cycle models.
