AB: Observations of ocean inert gas concentrations have been used to improve understanding of surface ocean oxygen cycling (Spitzer and Jenkins, 1989; Emerson et al. 1995) and gas exchange (Schudlich and Emerson, 1996; Hamme and Emerson, 2002). The interior distribution of these gases may also be useful for testing air-sea exchange and interior circulation estimates from ocean models. This possibility is considered as results from two global ocean model simulations with Ar and N2 as active tracers are compared to in-situ observations at ocean timeseries stations (Hamme and Emerson, 2002). Clear model-data differences are found and discussed in the context of modeled circulation and air-sea gas exchange parameterizations.
