The Gulf of Alaska data list 34 miscellaneous failures. Some of these may be 

 catastrophic failures since the records of all catastrophic failures were not preserved. The 

 missing profiles are considered miscellaneous failures because their precise status cannot 

 be determined. 



Of a total of 1987 attempts, 134 (6.7%) were catastrophic failures, 220 (1 1.1%) 

 were visually acceptable to depths between 50 m and the maximum depth, and 1581 

 (79.6%) were visually acceptable to the maximum depth. 



Figures 6, 7, and 8 are examples of a catastrophic failure, a partial success and a 

 success, respectively. Figure 6 is an example of a catastrophic failure, as indicated by the 

 3.5°C increase in temperature from 5 to 26 m. Figure 7 is an example of a partial success. 

 This profile gives visually acceptable temperatures from the surface to 89 m. Temperatures 

 for depths greater than 89 m are obviously incorrect. Figure 8 is an example of a success. 

 This trace gives visually acceptable temperatures from the surface to the maximum depth 

 of 460 m. In the absence of any other information, there is no valid reason to reject this 

 profile as incorrect. Also shown in each figure is the 16.7°C calibration check.
