a surface countercurrent , the Davidson Current, develops. This Davidson 

 Current flows northwestward along the coast within about 80 miles 

 of the California coast. 



Surveys of the California Current system, carried out under the 

 California Co-operative Oceanic Fisheries Investigation (CCOFI) Program 

 (Scripps, 1949-64), repeatedly touched the area covered by the 1964 

 surveys, but the sampling grids employed by CCOFI surveys were too 

 coarse to delineate small scale features. 



II. NARRATIVE OF OPERATIONS 



A. January 1964. 



REHOBOTH occupied 19 oceanographic stations along 5 lines radiating 

 from the coast of California beginning 21 January (Fig. 2). From 

 Nansen casts, serial-depth temperature and salinity measurements were 

 obtained, and water samples were collected for analysis of salinity 

 and dissolved oxygen, phosphate, and silicate. Additionally, 16 cores.
