Figure 2-8 shows an example of both a temperature
trace and a sound velocity trace from the AN/BQH-7A
recorder.
REVIEW QUESTIONS
Q11.
What additional feature of the AN/BQH-7A
bathythermograph system is an advantage over
the AN/SSQ-61A system?
Q12.
What is the main purpose of the auxiliary output
cable on the AN/BQH-7A?
Q13. Besides temperature, what additional type of
recording trace is produced by the AN/BQH-7A?
Q14.
What is the purpose of an Expendable Sound
Velocimeter?
EVALUATION OF SOUNDING
TRACES
LEARNING OBJECTIVES: Recognize the
anomalous recording indicators due to
equipment malfunction and other unusual
conditions in a bathythermograph observation.
Describe how temperature and water depths are
evaluated from a bathythermograph recording.
After the completion of a successful sounding,
temperature and depth levels are selected for encoding
and reporting.
The temperature traces from all
soundings must be evaluated for possible equipment
malfunction prior to encoding the data. Temperature
profiles from both types of recorders must also be
examined for inconsistencies. Although the paper
recording chart is slightly different, the indicators of
Figure 2-8.—AN/BQH-7A recorder stylus alignment in (A) temperature mode and (B) sound velocity mode.
