BACTERIA AND NUTRIENTS 



Cruise 237 



February 3, 1956 



Cruise Description ; Four bacteria profiles were taken on a 

 line extending seaward from the outer Los Angeles County sewer 

 outfall, A dye patch was followed from the inner boil. Several 

 hydrographic stations were occupied and a grid of stations was 

 run in which samples were taken for bacterial study.

* Results questionable - plugs were accidentally soaked with 



polluted water, 

 ** Experiment carried out with 0,015% fluorescein in sea water. 



Highest concentration of dye in actual samples: 5 x 10'^^ in 



3877-4; 1 x 10 "S"'''' in 3889-1.
