Questions for Exploration: Comparing Tides
Go to the tidal chart for Admiralty Head at this NOAA Tides & Currents link( https://tidesandcurrents.noaa.gov/noaatidepredictions.html?id=9447905&units=standard&bdate=20210719&edate=20210725&timezone=LST/LDT&clock=12hour&datum=MLLW&interval=hilo&action=dailychart) Below the tidal chart, change the date range to July 19-25, 2021 and click "Plot Daily." Using the resulting chart, answer the following questions:
1.At Admiralty Head, how many high tides and how many low tides are there in each lunar day?
2.Focusing on July 19 at Admiralty Head (make sure the dates of the chart are March 19-25) how much time passed between the first high tide of the day, and the first low tide? Report your answer in hours and minutes.
3.On July 19, what is the height of the highest tide in Admiralty Head?
4.On July 19, what is the height of the lowest tide Admiralty Head?
5.What type of tidal cycle does Admiralty Head experience? (choose diurnal, semidiurnal, or mixed)
6.Along the shore at Admiralty Head, you can see tidal pool communities at tide levels of 3 feet or lower. Sunrise on July 19 is at 5:31 am local time (LST); sunset is at 9:02 pm. At what time would you be able to see tidal pools during daylight hours on July 19? (HINT: Change the date range to July 19-20 to see the tides for one day
Examine tidal chart for Pensacola, Florida at this NOAA Tides & Currents link ( https://tidesandcurrents.noaa.gov/noaatidepredictions.html?id=8729840) Below the tidal chart, change the date range to July 19-25, 2021 and click "Plot Daily." Using the resulting chart, answer the following questions:
1. At Pensacola Beach, how many high tides and how many low tides are there in each lunar day?
2. Focusing on July 21 at Pensacola Beach, how much time passes between low and high tides? Report your answer in hours and minutes.
3. On July 21, what was the height of the highest tide in Pensacola?
4. On July 21, what was the height of the lowest tide in Pensacola?
5. What type of tidal cycle does Pensacola experience? (choose diurnal, semidiurnal, or mixed)
6. Portions of Pensacola Beach, a coastal community built on a barrier island, are located at 3 - 10 feet above sea level. Hurricane Sally, which struck Pensacola on September 16, 2020 and brought a 5.5 foot storm. Combined with a high tide on September 16, 2020, by how many feet did that storm surge submerge the lowest parts of Pensacola Beach? (Hint: use the information in question and change the date on the tidal chart to September 16, 2020)
Now, compare your answers above, and think about how the type (pattern) and size of the tides differ for these two locations.
As you have seen, Pensacola and Admiralty Head have very different tidal characteristics. Describe how a difference in location, shape of shoreline, and lunar declination likely contributes to the difference in tidal ranges and tidal pattern for these two locations. Use terminology and concepts from your module readings. Your answer should be at least one paragraph in length
Questions for Exploration: Spring and Neap Tides in Portland, Maine
Next, we will explore monthly tidal data for Portland, Maine and think about monthly tidal cycles. Go to the tidal chart for Portland, Maine at this NOAA Tides & Currents link ( https://tidesandcurrents.noaa.gov/noaatidepredictions.html?id=8418150&units=standard&bdate=20210701&edate=20210731&timezone=LST/LDT&clock=12hour&datum=MLLW&interval=hilo&action=dailychart) Below the tidal chart, make sure the date range is from July 1 - July 31, 2021.
14. What type of tide does Portland experience? (choose diurnal, semidiurnal, or mixed).
15. Review the concept of Spring tides in your textbook. On what dates (you should see two ranges of dates) do Spring tides occur at Portland?
16. Review the concept of Neap tides in your textbook. On what dates (you should see two ranges of dates) do Neap tides occur at Portland?
17. Using this chart of lunar phases (you may need to change the month to July), with what lunar phase do Spring tides occur at Portland?
18. Using this chart of lunar phases (you may need to change the month to July), with what lunar phase do Neap tides occur at Portland?
How do the sizes and timing of the spring and neap tides correlate with lunar phases at this location? Why do we expect this relationship?
Think about a coastal location in the US you have visited, or would like to visit. Using NOAA's Tides and Currents website, find the location, choose the site on the map, and then click "Station Home" to see details on the location. Spend a few minutes reviewing the data available for the site, noting the tabs across the top of the page.
Address the following in a posting to the Exploration Exercise #2 Tidal Differences in the US discussion forum:
• Tell us about the location. Where is the tidal station and when was it established? Give us some information about the area, including weather data, physical surroundings, characteristics of the shoreline, etc. (you may have to do some outside research) o Include a picture of the station in your posting, if available. o Also include a link to the station page.
o Lastly, see if you can find a picture of the shoreline at this location, to help us visualize the area.
• What are the characteristics of the tides in that location? Include information on tidal range, tidal pattern, and characteristics of high and low tides in a summary of the tides of your location o Include a current tidal chart for the location in your post.
