The spectra of sea reflectance coefficients, measured remotely from a ship in the region of the Urals oil spill, in the form of emulsion and individual films, have been analyzed. The pollution was detected in the Bering Sea near Cape Navarin on August 4, 2013, during the voyage of the Professor Khlyustin training ship. In situ flow-through fluorometric measurements of concentrations of the chlorophyll a and colored dissolved organic matter at a depth of 4 m, where the contamination effect was not detected, were used. The regression relations between remote and in situ measurements in clear and oil-polluted waters are analyzed. The preliminary technique is developed for detecting sea surface oil pollution, which is in emulsified form and in the form of small films about 1 m2 in area, using remote measurements of the seawater reflectance spectra.
