On the use of light scattering selectivity for the indication of the variability in the distributions of the large and small particles suspended in the water

The potentiality of the nephelometric indication of the relationship of small and large particles in shallow waters is investigated using a submersible nephelometer. One of its channels measures the light scattered from the water at an angle of 90° in the blue spectrum, while the other does the same in the far red. The results of the field observations demonstrate differences in the vertical distributions of the signals of the channels supposedly due to the vertical variations in the ratio of the concentration of the small and large particles.
