This system can be deployed from small vessels or inflatables. It can measure natural fluorescence, scalar irradiance of PAR (400-700 nm), water temperature, and depth to 100 m. Unlike strobe fluorometers, a natural fluorometer measures fluorescence emitted under the ambient light conditions that are driving photosynthesis in situ. The instrument has a depth range of 200 m and an operating temperature range of -5 degrees Celsius to 35 degrees Celsius."@en ; skos:notation "SDN:L22::TOOL1692" ; skos:note "accepted"@en ; skos:prefLabel "Biospherical Instruments Profiling Natural Fluorometer"@en ; skos:related , .
