On-effort ship survey tracklines (horizontal lines) off the northern coast of Wash- 

 ington between 1995 and 2002. The Olympic Coast National Marine Sanctuary 

 boundary is delineated and labeled. Dashed and dotted lines show three northern 

 lines surveyed only in 1997, the western extension of two lines surveyed only in 

 1996, and the southern four lines missed in 2002. 



In addition, dedicated photo-identification surveys 

 were conducted by Cascadia Research scientists us- 

 ing a 5.3-m Novurania rigid-hulled inflatable that was 

 launched from nearby ports and operated in areas 

 where whales were concentrated. Photo-identification 

 data in the present study includes data collected off 

 the northern Washington coast between 1989 and 2002 

 (Table 2). It also includes photographs contributed by 



other researchers and boat operators taken in the area 

 during this time (Table 2). 



Generally, photographs were taken with Nikon 8008 

 35-mm cameras equipped with 300-mm Nikkor telepho- 

 to lenses. High-speed black-and-white film (Ilford HP 

 5+) was pushed IV2 stops so that exposure times were 

 generally 1/1000 or 1/2000 of a second. Identification 

 photographs were taken with standard procedures used
