Tests of a number of infrared systems show that spatial resolution is extremely important when the oil is distributed in windrows and patches, emulsions are not always visible in the IR, and cameras operating in the 3 to 5 :m range are only marginally useful.

The polarization experiments consist of

measurements of the radiation emitted by a sea

surface covered by an oil film at two orthogonal

polarizations and the downwelling sky radiation at an

angle equal to the angle of incidence.
