Abstract

The possibilities of the definition of physical characteristics of organic films on the water surface, including oil thickness estimation, were studied in laboratory conditions based on the novel opto-acoustical approach. It was shown that the continuous infrared irradiation of film on the water surface leads to the generation of ultrasonic wave with frequencies of the order of several kHz which is the result of local heating of subsurface layer of water. The preliminary results regarding a relation between physical characteristics of surfactant films and the characteristics of acoustic wave are presented. A promising approach of remote sensing definition of surfactant films characteristics in real sea conditions was proposed on the base of these results. The development of this approach will contribute to the development of modern systems of strategic remote sensing of the ocean and inland basin.
