Gas‐water fluxes of CO 2 , O 2 , He, SF 6 and NH 3 have been calculated for conditions corresponding to the measurements of Liss et al [1981] for O 2 exchange and of Smith and coworkers [ Smith and Jones , 1986; Smith et al , 1991] for CO 2 exchange. For each experimental run, the best value of surface temperature was selected by matching the calculated transfer velocity to the measured value for O 2 or CO 2 , and fluxes of the other gases were then calculated for steady state, boundary layer, surface renewal and eddy diffusion models. The results indicate that the dual tracer method should work well for sparingly soluble gases under conditions where a surface renewal model applies, and moderately well under conditions where the boundary layer model is appropriate, but they leave open the question of when such models should apply.
