Question 2.
Why are tide gauges important?
Show hintHide hint
Consider what information you need to adjust measurements.
3Question 3.
What effect do tide levels have on hydrographic surveys?
- They do not affect measurements
- They can change the readings of water depth
- They only affect navigation
Show hintHide hint
Remember how tides fluctuate the water levels.
4Question 4.
True or False: Tidal corrections are optional in hydrographic surveying.
- True
- False
Show hintHide hint
Think about the importance of accurate measurements in marine navigation.
Question 5.
You are conducting a hydrographic survey in a harbor where tidal fluctuations can be up to 3 feet. If your raw depth measurement is 15 feet, calculate the tide-corrected depth during high tide.
Show hintHide hint
Consider the highest point the tide can reach when adjusting.
Question 6.
Different tide gauge types present varying accuracies. Choose a type of tide gauge for a coastal region known for heavy tidal waves, and justify your choice.
Show hintHide hint
Think about what type would function best in turbulent conditions.
