The effect of salt-water on heat transfer across the wind-driven air-water interface was investigated through laboratory experiments in a wind-wave tank. The results show that there is no difference in heat transfer coefficient on the water side between salt- and tap-water cases in the whole wind-speed region. This means that salinity has no effect on heat transfer across the wind-driven air-water interface. The results also show that in the middle wind-speed region, heat transfer coefficient in the salt-water case has a kink similar to that in the tap-water case. In addition, the frequency of the appearance of surface-renewal events in the salt-water case has the same trend against free stream wind-speed as heat transfer coefficient on the water side. These results suggest that heat transfer across the wind-driven air-water interface is dominated in both salt- and tap-water cases by the surface-renewal events just below the interface.
