Oils floating on the sea surface can be observed as "dark" patches radar images since backscattered signals from contaminated area are reduced in two dominant ways. First, oil slicks could damp short gravity and capillary waves responsible for backscattering energy. Second, oil-covered permittivity decreases significantly if film is sufficiently thick or mixed with seawater, i.e., emulsion. In this article, geometry of accounted by damping waves, which described model local balance (MLB)...
