Optical Backscattering metre (OBS)
An instrument built by Downing Associates and used to obtain in-situ measurements of light scattering in sea water. This measurement also provides a crude measure of the particle abundance in the water. The instrument works by projecting a beam of light into the water and measuring the amount of light scattered back to a detector place next to the source. The LSS is a similar instrument.
