FOREWORD 



The Naval Oceanographic Office conducted a detailed 

 environmental study in the Channel Islands area during 

 September and October 1965. Major emphasis was placed 

 on currents, sound velocity structure, and bottom com- 

 position. The proximity of the ocean stations to each 

 other on this survey allows a synoptic description of 

 the data obtained. This technical report describes 

 the effects on the ocean environment produced by the 

 California Current, daily tides, earth's rotation, and 

 internal waves. Also presented are discussions of 

 bottom composition and plankton distributions.
