this cruise not only do the lower stations show a southerly 

 and the upper stations a northerly component superimposed 

 upon a spreading of cards due to random dispersal, but returns 

 from individual stations demonstrate beyond question the 

 existence of such a divergence. After diverging, the water 

 flows out and rounds the points of land at the northern and 

 southern limits of the bay. The earlier anology between 

 Santa Monica Bay and a bowl with water spilling over the edges 

 is valid whenever the bay is being filled by an onshore drift. 

 However, it will be shown by later cruises that the currents 

 frequently flow either from the north or from the south and 

 that dxiring those times the bowl analogy does not apply. 

 Cruise of December 29, 1955 



The results of this cruise are presented on a single 

 chart (Fig. 90), because of the 288 cards released in Santa 

 Monica Bay and of the 49 (17%) that were recovered; all but 

 two were returned from outside the bay and were scattered 

 along the coast between Long Beach and Rosarito Beach, Baja 

 California. One card was found floating in the water at 

 Aval on Bay, Catalina Island. The maximum velocity determined 

 was 4 miles per day (0.16 MPH). 



Two cards were picked up by boatmen in Santa Monica Bay 

 the day following release. Each had drifted about 3 miles 

 from the stations of origin and were headed in such a direction 

 (west of south) as to take them out of the bay had they con- 

 tinued in their drift. 



During the day of release and during the following night 

 and morning the sea was calm. There was no wind of any conse-
