following release. On the night of July 26 between 9 p.m. 

 and 1 a.m., 491 cards were released. The station lines on 

 this and subsequent cruises were spaced slightly farther 

 apart to include more of the northern part of the bay. A 

 total of 227, or 45%, were recovered. 



Once more the predominant drift was toward the shore 

 with a moderate trend to the south (Figs. 107 and 108). 

 Some cards from the lower stations escaped through San Pedro 

 Channel. However, there was no evidence of a divergence in 

 the central part of the bay or of a westward drift in the 

 Malibu region. 



From Station 4474, 4 returns gave velocities of 4 to 

 4 3/4 miles per day (0.16 - 0,20 MPH), but there was one 

 whose velocity was 12|- miles per day (0.52 MPH). From 

 Station 4475, 2 cards gave velocities of 6^ and 12|- miles 

 per day (0.25 and 0.52 MPH), and one anaraolous card gave 

 16i miles per day (0.68 MPH). 

 Cruise of August 9-10 , 1956 



The current pattern on August 9-10 (Figs. 109, 110, and 

 111) was much like the one on the previous cruise, in that 

 the cards drifted toward the shore. Only two differences 

 in pattern were evident. There was some divergence in the 

 central part of the bay with a weak northerly branch, and 

 the drift to the south in the lower and offshore portions of 

 the bay was much better developed. This southerly trend is 

 well illustrated by the lack of returns from Stations 4507, 

 4508, and the three returns from 4513 (Long Beach to Huntington 

 Beach), in the lower offshore portion, and by the fact that
