Abstract : A mathematical model is developed for a hypothetical suspensoid of particulate matter in water. The assumptions are made that the particles are homogeneously distributed throughout the medium, the particles all are the same size, and they are all spherical in shape. The resulting expressions relate the particle radius and concentration to extinction coefficient, beam attenuance coefficient, and upwelling light. A logarithiconormal distribution is developed and it is concluded that this model does not supply enough data to determine the statistical parameters of this distribution. (Author)
