Abstract: Gas exchange experiments from large linear and circular facilities are presented which provide some more insight into the influence of waves on the gas exchange process. The experimental data do not support models which closely link the gas exchange rate to the spectral density of capillary waves. The gas exchange rate is also not significantly influenced by swell. The key parameter is rather the instability of the wave field which can be expressed by the mean square slope of the waves.
