3. Differential Tide Force

6. Getting Information from Tidal Data There are plots for four different stations of Observed Water Line Height (red line) above a standard reference point vs. time for a six day period. Each student should determine the average time between high tides and low tides for a different plot. Show your work in your notebook. Also determine the maximum and minimum Water Line Heights for the period and the difference. Record your station; dates; the two averages; and the maximum, minimum and difference in Water Line Heights.
