Abstract: Experiments to determine the effect on the rate of air-water transfer of oxygen of evaporation and condensation of water molecules have been performed using a laboratory wind-water tunnel in which the wind speed and water and air temperatures, and the humidity of the air can be controlled.Under evaporative conditions there is no • measurable enhancement of gas transfer due to destabilization of the near-surface water.In contrast, a reduction in the transfer rate by more than 30% is observed at intermediate wind speeds un der condensing conditions.This retarda ti on can be explained in terms of a stratiftcation parameter.Although, on average, evaporation dominates over condensation at natural air-water interfaces, there are regions and times when the retardation in gas transfer shown here may be of environmental importance.
