TOTAL MICROCONSTITUENTS: Figure 19 repre- 

 sents the total of all microentities, animate and inanimate, 

 enumerated in the study. The points of greatest concentra- 

 tion are positively correlated with the areas of greatest 

 turbidity. The same positive correlation existed between 

 total microorganisms and Gymnodinium flavum. This dinoflagel- 

 late represented 86 percent of total microorganisms and 

 65 percent of total microconstituents, and accordingly was 

 the primary cause of light attenuation.
