| Summary: | The paper discusses the possibilities of modelling the bi-directional reflectance distribution function (BRDF) in sea areas polluted by oil. Three sea basin models are considered: a coastal one free of oil, one polluted by an oil film and one polluted by an oil emulsion. The following concentrations of oil were compared: for the film, 1 cm<sup>3</sup> of oil per 1 m<sup>2</sup> water surface, for the emulsion 1 cm<sup>3</sup> of oil in 1 m<sup>3</sup> of water. The optical properties of <i>Romashkino</i> crude oil were taken into consideration, as were various angles of incident solar light. The conversion of BRDFs into a directional distribution of the optical contrast of polluted areas is demonstrated.
