An evaluation program was undertaken on a remote oil film detection instrument which uses the infrared reflectance spectrum of water surfaces at the 3 micron region. Hydrocarbon detection was based on a change in the 3.1/2.7 micron signal strength ratio. The evaluation program consisted of laboratory and in-situ phases. The laboratory phase showed that the instrument could reliably detect hydrocarbon films on a water surface while ignoring non-hydrocarbon films and other pollutants. The results of the in-situ phase in a congested commercial harbor generally verified the laboratory phase findings and established the instrument's ability to operate effectively in the marine environment.
