4 cards from this section. Quick, good the night before a test.
What are the two main types of tides?
Think about maximum and minimum levels of the ocean.
What occurs during a spring tide?
Relate it to full and new moons.
What type of tide occurs during the first and last quarters of the moon?
Consider what happens during the quarters of the moon phase.
True or False: Float-operated tide gauges measure tidal height using water pressure.
Think about how float gauges function and their mechanism.
If a tide gauge measures a depth of 5 meters at a high tide and, during the next reading, the same location records 3 meters during low tide, calculate the tidal range. Discuss the implications of this range for recreational maritime activities.
Consider the implications of navigating between these heights.
Analyze how inaccurate tidal corrections could impact a hydrographic survey's outcomes. What measures could be taken to ensure the accuracy of tidal data used?
Think about how various technologies and methodologies can help improve accuracy.
