Fraunhofer Line Discriminator (FLD) data collected from a natural oil slick in the Santa Barbara Channel compared favorably with simultaneous observations made by trained observers. Outdoor tank experiments demonstrated the ability of the FLD to detect small amounts of oil on a water surface. Oil was detected by a strong positive luminescence signal at the 486.1 nm Fraunhofer line for only two samples; sample 1 and Pennzoil, which were among the brightest samples analyzed in the laboratory. Digital image processing and enhancement techniques which are applicable to small data sets are discussed. Although detection of oil films on a water surface by means of airborne luminescence measurements appears feasible, the identification of the material comprising the film requires, at a minimum, an instrument with simultaneous multispectral capabilities and a knowledge of the luminenscence properties of the underlying water column.
