SeaOWL UV-A™ (Sea Oil-in-Water™ Locator)


 
General 
Product Name:SeaOWL UV-A™ (Sea Oil-in-Water™ Locator)
Product Description:Sea-Bird Scientific introduces SeaOWL UV-ATM, a new in-situ oil-in-water sensor. Based-upon the highly successful WET Labs ECO sensor, Sea-Bird Scientific has developed an industry-leading oil-detection technology with 5X optical resolution improvement over its predecessor. SeaOWL UV-ATM measures crude oil-in-water using the same UV-A excitation and blue emission wavelengths (370 nm EX/ 460 nm EM) currently used in the ECO CDOM fluorometer. The SeaOWL UV-ATM improves the resolution and range of the ECO with a greater depth of field, optimized electronics and dynamic gain stage modulation. The new dynamic gain provides industry leading sensitivity across a large detection range making saturation unlikely in even the most heavily impacted environments. The compact SeaOWL UV-ATM design also includes chlorophyll fluorescence and 700 nm backscattering measurements to discriminate crude oil from phytoplankton and other natural sources of FDOM.

Additional sensors 
Additional sensors:Chlorophyll EX/EM and FDOM EX/EM
Additional information:The compact SeaOWL UV-ATM design also includes chlorophyll fluorescence and 700 nm backscattering measurements to discriminate crude oil from phytoplankton and other natural sources of FDOM. Backscattering specifications are derived from a vicarious calibration with a MCOMS backscattering sensor. Scale factors for backscattering incorporate the target weighting function and the solid angle subtended for the MCOMS optical backscattering sensor. The SeaOWL UV-ATM is highly linear in response to changes in the particle concentration of a specific particle population.
More information 
Distinguishable features:Industry leading optical resolution. Wide dynamic gain prevents measurement saturation even within heavily impacted environments. Three parameters in a single sensor: chlorophyll, backscattering, and Fluorescent Dissolved Organic Matter (FDOM). Backscattering and chlorophyll fluorescence provide discrimination of crude oil from phytoplankton and other natural sources of FDOM.
