Final answer:
Changes in water salinity would NOT typically induce errors in a Doppler sonar log since Doppler sonar technology measures the movement of water particles and salinity's impact is negligible for its standard uses.
Step-by-step explanation:
When considering what will NOT induce errors into a Doppler sonar log, it's important to understand various factors that can affect its accuracy. Errors can be introduced due to the limitations of the measuring device, the skill of the person making the measurement, irregularities in the object being measured, and any other factors that affect the outcome.
Among the options provided:
- Incorrect calibration of the sonar device
- Interference from other sonar devices
- Changes in water temperature
- Changes in water salinity
Changes in water salinity would NOT typically induce errors in a Doppler sonar log, because Doppler sonar technology primarily measures the movement of water particles and the effect of salinity on this movement is negligible for standard uses of Doppler sonar.
