You have measured $O_2$ and $Ar$ concentrations in the surface ocean over the course of a month during the summer. Average water temperature and salinity were $25C$ and $35$ psu, respectively for the period of observation. Average $O_2$ and Ar concentrations were $225$ moles $\frac{?}{kg}$ and $10\mathrm{.}7$ moles $\frac{?}{kg}$ respectively. Both concentrations appeared to be at steady state.
