Optical Absorption Coefficient is the rate at which light energy is absorbed (removed) by seawater as a function of how far it travels (e.g. with depth). The Optical Absorption Coefficient reflects the absorption coefficient for the combination of all seawater impurities including all particulate and dissolved matter of optical importance.
