Hydrocarbon monitoring in water is of growing importance near oil platforms, marinas, and spill-affected waters. The stand-alone Turner sensors have been used extensively for oil monitoring. The crude oil sensor is useful for detecting oil throughout the water column in offshore monitoring. Closer to shore, where colored dissolved organic matter (CDOM) concentrations can be high and interfere with crude oil readings, the refined fuels sensor is recommended.
