WebThe OBS sensor measures infra-red radiation scattered by particles in the water at angles ranging from 140° to 165°. Infra-red radiation from the sensor is strongly attenuated in clear water (more than 98% after travelling just 0.2 m), (D&A instruments, 1989 [4] ). WebOptical backscatter sensors measure the amount of suspended material in the water column, including live phytoplankton, microscopic animals, and detrital (non-living) particles. In coastal regions, suspended inorganic material, such as clays and silt, also would be assessed. WET Labs Optical Backscatter sensors are deployed on the deep water ...
