Oceanography questions. Please, only answer if you really know the answers and you can answer ALL of them. Please don't answer it if you don't know the answer or if you cannot complete it. I need in-depth answers!
8. Stripped bass lay their eggs high up in the Chesapeak Bay; a slightly stratified (partially mixed) estuary. When the young fish hatch they need to swim all the way out of the bay, into the ocean. Where in the water column of the Bay should they go to have the easiest time making this trip? Explain.
9. Why might along A on the wave break before point B of the same wave?
10. What are the terms used to describe the water at point A and the water at point B?
11. The water laps up on this beach but does not break. Why do you think there are no breaking waves?
12. What is going on with the water pattern as it passes through the opening from point A to B?
Explanation / Answer
8) Stripped bass moves easily through rip currents. Rip current is a powerful flow of water from beach to the open ocean, sea, or lake. It can be greater than 45 meters wide, but most of them are less than 9 meters. This currents can move at a rate of 8 kilometers per hour.
9) Breaking of waves depends on the profile of ocean floor. Here point A is shallower than point B and due to this breaking of wave takeplace.
Ocean waves carry large amounts of energy. The amount of energy in a wave depends on its height and wavelength.As the energy of a wave passes through water, the energy sets water particles into orbital motion. Water particles near the surface move in circular orbits with diameters almost equal to the height of wave. The orbital diameter of the wave and the wave energy, decreases with depther. Under a depth of half wavelength, water is unaltered by the wave energy. When the depth of the water is greater than half the wave’s wavelength, that waves are deep water wave.The energy of a deep-water wave does not touch the ocean floor. When deep-water waves move into shallow water, the energy of the waves touches the ocean bottom, the water particles drag along the bottom and crush their orbit. When the water depth is less than one-half the wavelength, the water movement of particles on the surface changes from swells to steeper waves. Due to the friction of the deeper wave with particles on the bottom, the surface of the wave starts to move faster than the deeper parts of the wave. Then front surface of the wave gradually becomes steeper than the back surface. When the water depth is less than 1/20 th of the wavelength, it is called shallow-water wave. At this point, the surface of the wave moves very faste than the bottom of the wave and the upper part of the wave begins to drop over and fall down the front surface. This is called a breaking wave.
10) Point A - It is called shallow water waves; Point B-It is called deep water waves.
11) On a steep slope, the waves don’t touch the bottom until they it reaches almost at the shore. So they don’t have time to build up and break, it just surge far up the beach without breaking.
12) Diffraction take place as it moves frm A to B. It is the spreading of waves when they pass through an opening into another regions. It involves a direction change of waves. Water waves have the capability to move around corners or around obstacles and through openings.
