Abstract
Measurements of the evasion rate of CO2 and O2 from fresh water into air which have been performed in a wind wave tunnel show an increased slope of the k vs. u-curve at wind speeds above 11 – 13 m/s. In order to test the hypothesis that this effect is caused by the additional transport of those gases by means of air bubbles, the bubble spectra have been investigated by a photographic method as function of fetch, windspeed and water depth. Quantitative calculations, on the basis of these spectra and of the additional fluxes of CO2 and O2, showed good agreement with the experimental data.
