The below graph and table indicate the tidal highs and lows at Sebastian Inlet over a two day period, November 12-13, 2012.

How many high tides are there on the first day? 1/2/3/4 2. How many low tides are there on the first day? 1/2/3/4 3. What type of tidal pattern does this site exhibit? Hint: For semi-diurnal mixed tides, the difference between successive high tides AND low tides must be significant (>=.5 ft.) Diurnal / semi-diurnal / semi-diurnal mixed 4. What is the maximum tidal range, in feet, between two successive tides, i.e. a single high and low tide, or low and high tide, over these two days? For example, if a high tide is 2.4 ft and the next low tide is .9 ft, the tidal range for that high to low tide is 1.5 ft. You need to calculate this for each high to low tide and for each low to high tide. 5. How much total time, in hours and minutes, elapsed between the earliest high tide on the first day and the earliest high tide on second day? Hint: Don't forget to include the hours of the entire day that has elapsed!________ hours and minutes 6. Theoretically (check your textbook), how much total time should have elapsed between these two high tides? hours and minutes Part 2: Navarre Beach: 2.88 1.88 1,60 1.40 Height (Feet relative to MLLH) 1,28 1.00 8,80 8.60 8.40 0.20 0.00 -0,20 11/12 12an M 11/12 6pm 11/12 Gan 11/12 12pm Date Day 2012/11/12 Mon 2012/11/13 Tue 11/13 12an 11/13 Time 03:42 AM 04:53 AM Date/Tine (LST/LOT) Hgt 0.22 L 0.0 L 1.

Hint: For semi-diurnal mixed tides, the difference between successive high tides AND low tides must be significant (>=.5 ft). Diurnal semi-diurnal / semi-diurnal mixed 4. How much total time, in hours and minutes, elapsed between the two successive high tides? hours and minutes 5. What kind of tidal current is occurring when the tide is going out? (Choose one) Ebb/flood/ slack Waxing Gibbous (between 50 and 100%) Full Moon (100%) Part 3: Moon Phase and Tides: Use the below diagram to answer the next few questions. The % moon visible is an indicator of the moon phase. If the moon is full, you will see 100% of the side of the moon facing us, and therefore the % moon visible is 100%. If the moon is a new moon, you will see nothing of the side of the moon facing us, and therefore the % moon visible is 0%. Moor Spring Tide Waning Gibbous (between 100 and 50%) 1st Quarter (50%) Neap Tide Earth Neap Tide 3rd Quarter (50%) Spring Tide Waxing Crescent (between 0 and 50%) Moon New Moon (0%) Waning Crescent (between 50 and 0%) SUN 1. The % moon visible is 6% for November 12th and 1% for November 13th at these two sites. Choose the appropriate phase of the moon in the above diagram for the first date. Hint: You may need to look at the second date to determine whether it is waxing or waning. New Moon / Waxing Crescent / 1st Quarter / Waxing Gibbous / Full Moon / Waning Gibbous 3rd Quarter / Waning Crescent 1 2. What kind of tides are these sites experiencing? Choose one: Neap Spring 3. Based on the % moon visible during these two days, how will the tidal range change on the day AFTER these two days? Choose one: It will increase / It will decrease
