SHALLOW WATER TURBIDITY STUDIES, by T. F. Ball and 

 E.C. LaFond. 26p., 26 July 1962. UNCLASSIFIED 



Hydrophotometers were used to measure the light transparenc 

 of water near the USNEL Oceanographic Research Tower in an 

 attempt to correlate turbidity with time, temperature, and 

 biological aspects. It was found that maximum turbidity fre- 

 quently occurs at or near the level of maximum temperature 

 gradient. Turbidity was ^hown to be caused principally by con- 

 centration of plankton. It is recommended that additional stud- 

 ies be conducted in other areas for comparison with data from 

 Mission Beach.
