Description

The Optical Beam Attenuation Coefficient is the rate that the intensity of a beam of light will decrease in response to the combined effects of absorption and scatter as a function of propagation distance. The Attenuation Coefficient results from the spectral beam attenuation of the combination of all seawater impurities including all particulate and dissolved matter of optical importance.
