Signal Beam Attenuation (OPTCSIG)

Signal Beam Attenuation is a measurement of beam intensity after propagating through a seawater sample, i.e. the amount of light that reached the receiving detector. By dividing the Signal Beam Attenuation by the Reference Beam Attenuation the proportion of light absorbed or scattered as the light travelled to the receiver detector can be calculated. These values are part of the calculation for Optical Beam Attenuation Coefficient.
