GULF OF ALASKA 



The Gulf of Alaska XBT measurements^ were made from the USNS S.P. LEE in 

 transit between San Diego, CA, and Kodiak, AK, and during eight acoustic experiments and 

 two environmental surveys. The locations of these measurements are shown in figure 2. 

 XBT measurements were made along the transit lines shown in figure 2a and at the locations 

 labeled ABLE, CHARLIE, and PAPA, where acoustic experiments were conducted. The 

 dashed lines in figure 2b, an enlargement of the area labeled INSET in figure 2a, show 

 the tracks of the two environmental surveys with two of the eight acoustic experiments
