to have escaped the bay on its voyage and drifted out through 

 the San Pedro Channel. It was recovered at Alamitos Bay two 

 weeks after it had been released. Whether the cards were 

 trapped in a large counter-clockwise gyral extending well 

 outside the bay, or simply drifted about for a time offshore 

 and then were carried eastward by a reversal in current 

 direction, is not known. 



Inspection of Figures 84 and 85 shows that in Area II 

 a well-defined current flowed to the north in the inshore 

 region. At least a portion of this current rounded Point 

 Dume and four cards were deposited near Zuma Beach. Two 

 cards, one from Station 3427 and one from Station 3434 came 

 ashore near Redondo after 10 to 12 days. These may have 

 been carried along with cards from Area I and returned to 

 the bay only after a relatively long journey. 



A total of 334 cards were released, and 145 returned 

 (42%). Current velocities were generally low, of the order 

 of 6 miles per day (0.25 MPH) or less. 

 Cruise of September 29 , 1955 



An entirely different current pattern existed three weeks 

 later. The only similarity to the September 8 cruise was that 

 the bay could likewise be divided into areas, in this' case 

 W three, depending upon the behavior of the cards released (Fig. 

 86). 



Area I lay offshore and included all of the 7-mile stations 

 but one, and two 5-mile stations in the southern sector. From 

 this area all recoveries without exception were made to the 

 south and outside the bay. These recoveries are shown in
