 sailed together from the Strait of Juan de Fuca 

 directly to Unimak Pass during 20-28 June, 

 worked in the Bering Sea from 1 July to 5 

 September, and returned to Seattle viaKodiak, 

 Sitka, and the inside passage through south- 

 east Alaska in September. 



Hunting methods, field examination of fur 

 seals, laboratory methods used in preparing 

 and determining the ages of fur seal teeth, 

 and analysis and identification of stomach

RESEARCH IN 1963 



Distribution of Seals by Time, Place, and 

 Numbers 



Distribution by time . --The vessels sailed 

 parallel courses to Unimak Pass, usually 

 keeping within 2 miles of each other. Seal 

 watches were maintained during daylight, and 

 all seal sightings were recorded. Figure 1 

 shows the daily run of the vessels and the 

 number of seals seen.
