Abstract : A field test of three fixed site, oil on water point sensors was conducted in New York Harbor. Over 2000 hours of strip chart recordings were analyzed to determine such items as, number of alarms for various threshold levels and time durations, effects of tidal fluctuations, effects of oil background levels, and sensor reliability. In addition, surface samples were obtained and analyzed to provide ground truth data. To be operationally desirable, the sensors comprising a local area surveillance system must unequivocally initiate an alarm in one circumstance only. That is the case when there is a surface oil film large enough to warrant cleanup, preventative measures, or legal action. It appears that it would be more effective to monitor specific problem areas such as moored tankers or storm drain outfalls.
