16.7°C ±0.1°C temperature on the chart. The chart drive will then stop. On the test panel 

 of the recorder is a switch with -1.1 °C and 34.4°C positions. Pressing the switch to the 

 -1.1°C position should record a temperature of-l.l°C ±0.rc,and pressing the switch to 

 the 34.4°C position should record a temperature of 34.4°C ±0.1°C on the chart. If these 

 temperatures are not recorded, the entire system must be recalibrated according to 

 procedures described in the operating manual. 



XBT PERFORMANCE SUMMARY 



Table 6 summarizes the performance of the XBT systems used to obtain each of 

 the data sets. Shown for each XBT system are the number of attempted XBT profiles, 

 catastrophic failures, miscellaneous failures, successes, partial successes, and visually 

 acceptable XBT profiles.

Notes: 



CF = Catastrophic Failure: No usable measurements for depths greater than 50 m. 



MF = Miscellaneous Failure: Failed because of operator error, wire blowing against ship, etc. 



S = Success: 



PS = Partial Success: 



VA = Visually Acceptable: 

 ^1830-m XBT profiles. 



Visually acceptable to maximum depth. 



Visually acceptable to a depth greater than 50 m but less than the 

 maximum depth. 



The sum of the success and partial success. No basis for rejecting as 

 incorrect, based on a visual inspection of the analog record.
