13 ABSTRACT 



An investigation of time and space distribution of microorganisms and other 

 materials producing attenuation of light in the open sea. Unicellular organisms 

 in bloom quantities are found to reduce transmission of yellow light. Dinoflagel- 

 lates are especially important during the summer off Mission Beach, California. 

 Light transmission is also reduced by organic, material, particulate detritus, and 

 dissolved pigments. Macroplankton are found to be less important contributors.
