Influence of surface-active film on statistical characteristics of wind waves

Experimental investigation of surface-active films' influences on statistical characteristics of wind waves was conducted in ring pool by the use of laser scanning locator. It has been shown that the film's influence on the sea surface causes a significant change of statistical characteristics of the surface. The degree of the influence depends on the composition and concentration of the films. It has been shown that the SAM-films' appearance on the water surface can be clearly registered by the use of the laser scanning locator down to very small concentrations of about some fractions of mg/m.
