farther from shore the releases were made, the farther 

 southward the travel before recovery. 



NOVEMBER 1964 



The cruise during November 1964 yielded the fewest 

 recoveries (9%), 24 of the 276 released (Fig. 3, Table 3). The 

 few recoveries prevent defining any clear pattern of 

 circulation for this time of the year, but a generally slow 

 northward flow is evident from all but one recovery. 



There were 18 recoveries (12%) from 156 releases along 

 the trackline normal to the Washington coast. Two of the 

 bottles released at the station closest to shore drifted into the 

 Strait of Juan de Fuca and were recovered at the southern tip 

 of Vancouver Island. These recoveries were reported 5 wk 

 after their release and suggest a general northerly flow along 

 the coast at 5 to 8 cm/s (minimum) with an appreciable 

 onshore component, particularly at the entrance to the Strait 

 of Juan de Fuca. The single recovery from the adjacent 

 station along this trackline was reported from Montague 

 Island in Prince William Sound, Alaska (lat. 59°50'N, long. 

 147°45'W), whereas the recovery from the station nearest 



Cobb Seamount was reported from the central portion of the 

 west coast of Vancouver Island. Of the 10 remaining stations 

 along this trackline, recoveries have been reported from only 

 3, and all but 1 of the 14 recoveries were from the Washington 

 or Vancouver Island coasts. 



Only six recoveries (5%) have been reported from 120 

 releases at the 10 stations along the trackline normal to 

 Vancouver Island. All of these were from only five stations, 

 and all recoveries were made north of the release area; four of 

 the six recoveries were in Laredo Sound (about lat. 52°30'N, 

 long. 129°W). 



JANUARY 1965 



The winter cruise from 13 to 18 January 1965 was unique 

 because recoveries were made from nearly all the 21 release 

 stations. A total of 252 drift bottles was released and 76 were 

 recovered (Fig. 4, Table 4)— a 30% recovery. Speed and 

 direction of surface flow are indicated by first recoveries from 

 each station that fell into three different time groups: 1) 

 recoveries within 11 to 24 days released within 130 km (70 

 nautical miles) offshore indicate the extension of the
