Growing intensity of marine transport results in the increase of the amount of oil pollution released into the sea water. The presence of oil in the sea, which is thought to have come from accidental spills or tanker disaster, is connected mainly with the daily operation of marine engines. Pollution from ships engines, can reach the sea water masses together with ballast or bilge water as the result of human error or a failure of marine equipment. This paper is focused on a comparison of the optical properties of marine waters and oil substances. These include the spectra of absorption coefficient, spectra of scattering coefficient and scattering phase-function (for different wavelength) which describes an angular distribution of scattered light intensity in the sea water. The light scattering phase function depends on the water constituents like mineral suspensions, zooplankton and phytoplankton cells, gas bubbles or so-called yellow substances as well as oil droplets of water pollution. Detection of oil substances in the sea can be effective when it is done remotely, from ships, buoys, inshore or offshore towers, the decks of aircraft or satellites. The knowledge of the listed above properties of natural (clean) seawater is necessary, because they determine the field of light coming out from the sea and allow interpret images of sea surface from point of view of crude oil and the petroleum products detection. In this study we also discuss optical contrast of oil residuals in the sea in various sea regions.
