The paper covers some results of laboratory and nature experiments on studying the effect of oil films on water evaporation rate and oxygen concentration in sea water.

It is demonstrated that oil films on the sea surface reduce the rate of water evaporation by 15 to 33% due to diffusion resistance of oil film as well as energy resistance of monolayer of surface active substances at the film-water interface.

Large oil spots may cause, in areas oversaturated with oxygen, increase of oxygen concentration in sea water under the oil spot due to decrease of gas exchange rate at the sea-atmosphere interface.
