Oceanography
Diurnal tides are the daily ones, and have a single high tide and low tide, respectively, each day. Semidiurnal tides have two high tides and low tides each lunar day, both of which are always at the same height. Mixed tides are when there's two high tides and two low tides, but the high tides are at different heights and the low tides are at different heights.
Ocean depth and rotational velocity also influence the heights and times of tides at any given location.
Spring tides occur during full moons and new moons, and are the most extreme tides that affect the sway of the ocean's currents the most. These occur when the sun, the moon and the earth are aligned. This produces the highest high tide and the lowest low tide. The neap tide occurs during a crescent moon and during a three-quarters phase of the moon, and takes place due to earth, moon and sun forming a right angle so that the solar tide makes the lunar tide smaller.
The predicted water level.
From 0 to 2,500 feet.
6. A mixed tide.
7. About 5 minutes to 4 p.m.
8. From -2,000 feet to 14,000 feet
9. Semidiurnal
10. The difference between the low tides and the high tides increases significantly as the week progresses.
11. The greatest is approximately 2,000 feet. The least is approximately 500 feet.
12. The tides are significantly different. The disparity between the high and low tides in Florida is practically insignificant when compared to the huge sweeping difference (of at least 12,000 feet) in the high and low tides in Maine. These differences can not only be attributed to the difference in locations from the sun and the moon that these two places are on the earth, but can also be related to the ocean depth and the rotational gravity of these respective places.
13. The 11th and the 26th
14 Approximately 17,000 feet on the 26th and roughly 11,000 feet on the 11th.
15. On the third and the 19th.
16. About 3,000 feet.
17. Actually, the dates for the spring and neap tides are different in Alaska than those for Maine. This is due to the fact that the relation of these areas to the sun and the moon are different. Therefore, the days and times of their respective full moon, new moons, etc., are inherently different.
Where, sharp increases or decreases in the temperature could have an effect on the eco system. As any one of the vital pieces of the food system and their way of life; would have ripple effects based on slight changes in temperature. This has the possibility of setting off a mass extinction. (Garrison, 2008) The obvious effect on land would be that humans depend on the ocean as a source
Oceanography Comparing Approaches to the Carbon-Based Productivity Model: Assessing the Sensitivity of Remote Sensing-Derived Phytoplankton Productivity to Mixed Layer Depth. The purpose of this review is to compare approaches or variations of approaches that are being used to assess the sensitivity of phytoplankton productivity to mixed layer depth. The challenge to clarifying controls on primary productivity and the related responses and feedbacks is a key objective of research on global change. In order
On January 11 at 3:00 AM, high tide reaches its first peak at 31.248 feet at high tide. The corresponding low tide of this same day hits at 10 am at around 3.517 feet. There is a dramatic difference between the two tides occurring twice a day. On that same day, the second round high tide is at a height of 29.588 at 5 pm, a lesser degree than
Calculate the distance from the mid-ocean ridge to each of the sites The distance from the middle of the ocean ridge each of the different sites would include: 878 km for site 14; 556 km for site 15; 300 km for site 16; 711 km for site 17; 556 km for site 18; 1189 km for site 19 and 1522 km for site 20. How many kilometers correspond to 1o? 900,000 km. Where is
They are responsible for transporting the heat from tropics to mid-latitudes. On the other hand, speed is said to be lower in the case of eastern currents (e.g. California Current) which transport cold water to the tropics where this is heated and pushed back to the poles by the western streams. Consequently, ocean surface currents help the Sun energy spread from the equator to the poles ((http://science.hq.nasa.gov/oceans/physical/OSC.html). Swells, breaking surf,
It is difficult to assess to what extent these changes be contributed to global warming, however, due to the relatively short history of observation available to oceanographers. The events put forth in the Pentagon Report are a plausible scenario, although many scientists contest the events as something which is not likely to happen in the near future. There is every possibility though that if climate change continues due to
