The Particulate Matter in the Sea as Determined by Means of the Tyndall Meter

Abstract

The Tyndall scattering has been studied for different material occurring in the sea, such as minerogenic matter, calcareous matter, and some marine organisms. It is shown that the scattering is proportional to the total surface of the particles provided that they are larger than 2 μ. This relationship is practically independent of the concentration. The size distribution of particles in marine waters is discussed with a view to estimate the amount of matter removable by sedimentation.
