of the bay, the beaches are well populated in sximmer jind 

 surprisingly so during the winter months when there seems 

 to be scarcely a stretch of beach that does not have a few 

 strollers each day. Because of this and the fact that the 

 currents were frequently directed toward shore, the per- 

 centage of recoveries was high. In all, 5,236 cards were 

 released during the year, and 1,803, or 34% have been 

 recovered,. Returns from the last two cruises, August 9 and 

 10 and August 20 and 21, are still incomplete. 



Fourteen cruises were made beginning September 9, 1955, 

 and ending August 21, 1956, Twelve of these were made along 

 a series of six lines each about two miles apart, and 

 extending out from the beach to a distance of approximately 

 seven miles. There were three stations on each line, one at 

 three, one at five, and another at seven miles from shore. 

 The position of two stations was adjusted so that they fell 

 at the approximate locations of the proposed sludge and 

 effluent outfall terminals. In addition to these 18 stations, 

 one was usually included in the southern inshore portion of 

 the bay. The other two cruises involved only a few stations 

 each and were made incidentally in connection with other 

 field work, A typical example of the stations and the area 

 covered by the regular cruises is shown in Figure 81, p. 182. 



The drift cards used in this survey consisted of two red- 

 striped labels, a self -addressed prepaid return envelope, and 

 a letter requesting information on location, date, and time 

 of recovery. These were enclosed in a transparent plastic 

 envelope. The envelope was made of polyvinyl flat seamless
