Abstract
Gas exchange experiments have been carried out in the Heidelberg circular wind tunnels and the large linear I.M.S.T. wind/wave facility in order to study the wave field and Schmidt number dependence of gas exchange. With a smooth water surface the experimental results agree well with the model treating the water surface as a rigid wall both in the Sc−2/3 dependence and the absolute rates. Gas exchange rates with a rough wavy surface are 3–5 times higher than in the smooth case and the Schmidt number dependence is lower (Sc−n, n = 0.55 ± 0.05). The total square wave slope seems to be a more appropriate parameter to describe the enhanced rates than the capillary wave slope.
