Measurements of the volume scattering function were made from 0.1° to 1.0° from the main beam for two types of phytoplankton (Amphidinium C. and Thalassiosira F.) and one quartz suspension. The functions obtained were quite flat within that angular range as predicted by theory. Using particle size distribution measurements and tables of theoretical scattering values the theoretical volume scattering functions of the samples used were also determined. The theoretical volume scattering functions for particulate indices of refraction of 1.02 and 1.15 were close in value to the obtained functions for the phyto-plankton but the measured scattering function of the quartz particles was much higher than the theoretical prediction. The explanation for this probably lies in the fact that the quartz particles have a significantly higher composite index of refraction than either of the phytoplankton. The results of this experiment are part of a system of experiments that will be made to be able to determine the index of refraction distribution of oceanic particulate matter.
