Tides Are More Than Just Tides
What is the definition of tides? The definition of tides is, as Tom Garrison defines the term, "Periodic short-term change in the height of the ocean surface at a particular place." (Oceanography pg.318). Also, knowing tidal heights will come to a great advantage for sailors traveling in and out of harbors, because if a sailor is sailing a large boat in a high-high tide into the harbor and there is a bridge then the boat will consequently crash into the bridge. Contrary to this, if the sailor is sailing into the harbor in a low-low tide the sailor will not be able to make it to the dock due to the water being low. Thus, the sailor needs to travel out at a tide in which the boat will not be at the same height as the bridge, and sail in the harbor at the time there is enough water to go into the dock at a specific time and day, which is similar to the lab exercise in which

Specifically, gravity from the sun and the moon pull particles (water) from the earth toward the direction of the moon and the sun. However, the moon has a higher influence on the gravitational pull than the sun, because even though the sun is much larger than the moon the moon is significantly closer to earth than the sun. Additionally, this means that the moon will have a greater influence on the gravitational pull. Together the sun and the moon both work together to influence the tidal heights. For example, at the time "when the moon, Earth, and sun form a right angle."(Oceanography pg.321) which forms neap tides. Neap tides "high tides are not very high and low tides are not very low."(Oceanography pg.321). However, at the time the Earth, sun, and the moon align together a spring occurs. In spring tides "high tides are very high and low tides are very low." (pg.321). Surprisingly, after spring tides a considerably strange fish comes to shores which is the
On average a given spot will experience two high tide and two low tides in a day. The tides are experienced due to the moon gravitational pull. The low tides are experienced when we are facing 90 and 180 degrees away from the moon. Then the high tides are found when we are facing the moon and when we are facing away from the moon.

... consider some ideas of what can be done to further enhance the management of the coastal issue. Using the research action plan, I aim to acquire a sophisticated understanding of longshore drift, coastal management and implementations of coastal issues, through the research action plan. Most importantly, I will include various diagrams explaining how the process of longshore drift occurs and what implementations it has on coastal environments, accompanied by an explanation of how the issue is being managed, a detailed outline of the geographical processes involved and a discussion of the impacts of the issue and why it is important.
Carson begins to propose that the moon is in fact responsible for pulling currents in certain movements, rhythms, and speeds depending on the location. Her way of further explaining includes calling out to her readers. She uses this tactic to let her readers subconsciously add vital input in proving her claim. “Anyone who has lived near tide wafer knows that the moon, far more than the sun, controls the tides. He has noticed that, just as the moon rises later each day by fifty minutes, on the average, then the day before, so, in most places, the time of high tide is correspondingly later each day." (The Moving Tides, pg. 1)
Sara M. Evans, in her book, Tidal Wave: How Women Changed America at Century’s End, chronicles feminist activities over several decades from just before the beginning of the women’s liberation movement in the 1960’s through the 1990’s. Doctor Evans was born in 1943 and currently teaches at the University of Minnesota in the history department after receiving both her B.A. and M.A. at Duke University and then later her PhD from the University of North Carolina Chapel Hill.

In “The Fish”, Marianne describes the perpetual cycle of life and death that occurs within the sea. The poem introduces the sea as a cruel and hostile force, and compared to “black jade” for its ability to blot out light. It is later in the poem that the sea’s nurturing nature is exposed and acts as a refuge for the “ink- / bespattered jellyfish, crabs like green / lilies, and submarine
Using this we can predict that the lowest tide of the first week occurred at t_min= 124.58 hrs and h(t_min) = −0.86 ft. This predicts there is a low tide at 4:35 am on Sept. 6 of -.86 ft. The actual low tide occurred at 3:35 am on Sept. 6 of -1.0 ft. The prediction was off by 60 minutes and 0.14 ft. Using the same process we can predict the highest tide of the first week. Here we get the max occurring at t_max= 142.56 hrs and h(t_max) = 6.40 ft or Sept. 6 at 10:33 pm with a height of 6.4 ft. The actual is a tide of 6.7 ft at 9:36 pm on Sept. 6. This time we were off by 0.3 ft and 57 minutes off. This model proved to not be 100% accurate, however, only 4 cosine functions were used to predict the tides while most models use up to 12 and the addition of more functions and parameters would create more accurate predictions.
A fish is a creature that preceded the creation of man on this planet. Therefore, Bishop supplies the reader with a subject that is essentially constant and eternal, like life itself. In further examination of this idea the narrator is, in relation to the fish, very young, which helps introduce the theme of deceptive appearances in conjunction with age by building off the notion that youth is ignorant and quick to judge. Bishop's initial description of the fish is meant to further develop this theme by presenting the reader with a fish that is "battered," "venerable," and "homely." Bishop compares the fish to "ancient wallpaper.
I have been keeping my feelings and negative emotions bottled up inside for too long. I feel that on a positive note, the tidal wave symbolizes the clearing away of old habits. Like franklin Roosevelt said “A smooth sea never made a skilled sailor." 5. Sun and moon
Tides are common features of the ocean. Tides occur when large bodies water rise and fall, because of the gravitational pull of the moon and the sun. Spring tides are especially strong tides; in spite of the name they have nothing to do with the season spring. They occur when the Earth, the sun, and the moon are in a line. Spring tides occur during the full moon and the new moon. Neap tides are especially weak tides. They occur when the gravitational forces of the moon and the sun are perpendicular to one another. When water moves from side to side, it is called a current. Currents move warm and cold water to different parts of the ocean.
