An instrument for the measurement of the volume absorption coefficient of horizontally stratified water


Contract NObs-72039. Task 5. Report No. 5-4. For the solution of many problems having to do with underwater photography, vision, and television it is important to know the absorbing and scattering properties of the water. By this is meant the separate values of the absorption coefficient and the scattering coefficient.Instrumentation has already been devised to measure the total attenuation coefficient, which is the sum of the absorption and scattering coefficients and consequently it is only necessary to measure one of the two latter coefficients to evaluate all three.
