Abstract
The article deals with the morphological features of spreading films of surfactants on the surface of the reservoir on the basis of experiments on the Gorky reservoir under various meteorological conditions. The test substances were: oleic acid, vegetable oil, diesel. The registration of film contamination was carried out using X-band digital coherent radar MRS-1000, located on the roof of the lighthouse at the end of the outside harbor. The processing of the obtained radar panoramas made it possible to establish that the physical properties of the pollutant are reflected in the morphological characteristics of the film slicks. In particular, the substance properties are manifested in relation of the slick axes along and across the wind direction, as well as in the effects of growth and saturation of the slick area, all other things being equal. Without claiming to be a method for identifying a substance based on the data obtained, we can conclude that these effects are present and that they can be observed using radar methods.
