Optical Attenuation
Optical absorption and attenuation instruments allows total scattering to be derived for living and detrital particles in the ocean. Since 2014, optical attenuation sensors have been installed near the seafloor on Benthic Experiment Packages at the Oregon Shelf and Offshore sites, on the Shallow Profiler Mooring Science Pods at Axial Base, Slope Base. and the Oregon Offshore sites. Axial mooring (LJ03A) and near the seafloor associated with secondary junction boxes by the moorings at Axial Base and Slope Base.
Spectrophotometer instruments on the Cabled Array are provided by WET Labs, the AC-S instruments.
