Ceratium furca: The distribution of C. furca (fig. 25) 

 generally paralleled that of C. fusus and demonstrated the 

 same relationship to turbidity. The low concentrations 

 made it highly unlikely that C. furca contributed grossly to 

 light attenuation. Rather, these concentrations were 

 additive, turbidity being a function of a collection of parti- 

 culate matter and dissolved substances rather than of any 

 single organism.
