Optical Beam Attenuation Coefficient is the rate at which light energy is absorbed and scattered by seawater as a function of how far it travels (e.g. with depth). The Optical Beam Attenuation Coefficient results from the spectral beam attenuation of the combination of all seawater impurities including all particulate and dissolved matter of optical importance.
