Oceanography

Athens is the capital of Greece. Athens is near the Aegean Sea.

Ocean temperatures and winds are coupled into a complex interactive system. Varying ocean temperatures affect local atmospheric pressure, which creates regional wind patterns that, in turn, drive oceanic currents that affect surface ocean temperatures. This movie illuminates how these processes interact to produce our climate system. In a way, the oceans absorb the suns solar rays, then the currents shift the heat around the globe warming the land during winter & cooling them during the summer.

yes algaes are the most primitive and all became diverse due to evolution

Pacific ocean

The water temperature in late March usually average between 70 to 74 degrees

When a wave goes from deep water to shallow water, it decreases in size and strength. This is because shallow water does not have the required power to transmit the wave, and so its velocity decreases.

'Suspension' or as you cited in your question 'suspended load'. Fine materials can be suspended in the water and are carried away in such a method. These particles are too light to sink to the bottom of the fast moving river. Suspension load forms the largest part of the river load. Materials that can be suspended include silt, mud and clay.

The height of artificial levees must be increased periodically to account for changes in water levels and to maintain their ability to protect against flooding. Factors such as erosion, settling, and increased water flow can contribute to the need for periodic height adjustments to ensure the levee's effectiveness is maintained.

T he Red Sea is the saltiest ocean in the world.

it starts out as water in a ocean. it then goes to the next step called evaporation. evaporation is when the clouds "suck" up all of the water. after evaporation is condensation. condensation is where the water becomes a cloud from all of the water vapor in the air. after condensation is precipitation. as you may know, precipitation is when we get rain, snow, hail, or any other types of "water falling from the sky" after that the water may go to the ground and become groundwater and fall right back to the ocean where the water cycle will start over again.

Yes, deep-water and shallow-water waves can exist at the same point offshore. In areas where the water depth changes gradually, both types of waves can coexist in the same location. Deep-water waves occur in deeper waters where the water depth is greater than half the wavelength, while shallow-water waves occur in shallower waters where the water depth is less than half the wavelength.

All submarines have several methods by which they can determine a general navigational position or a precise navigational fix:

1. GPS Satellite Network or SatNav fix

2. Electronic Gyroscope

3. Dead Reckoning plot

4. Radio Bearing

5. Visual Aid (close to shore, e.g., lighthouse, landmark, etc.)

6. Sunline (Sextant can be used when surfaced, or attached to Periscope while submerged)

7. Radar

For target range calculation, it depends on whether or not it's a visual and Sonar target, just visual, or just on Sonar. Visually, range markers on the Periscope indicate estimated range, however unless circumstances warrant, that range will always be verified and compared with Sonar range.

Sonar ranges are determined over time by tracking the target through induced turns (zigs), either by the submarine or the target. Either way, the change in direction adds another leg to the target tracking solution; eventually an estimated range based on known, sound trigonometric calculations weil be formulated, either by computer (normal) or by hand (backup). The tracking solution takes into account several known variables given by Sonar:

1. Estimated target speed (RPM) and type (e.g., Merchant, Warship, Trawler, etc.)

2. Sonar bearing

3. Closing or Opening Range (target getting closer or moving away)

Sonar's given target tracking information is based on the current sound profile for the given operating area the submarine is in, as all information is based on the current speed of sound in water, which can change.

In the end, target speed, bearing, and course are the key factors in determining range prior to a torpedo shot; however, in most circumstances, the shooting submarine will check a target's range with all other information plotted with active Sonar echo ranging (usually only 1 or 2 pings to verify range). If the range matches the plot, the information is fed into the torpedo guidance computer prior to shooting.

Neritic Zones

Earth's crust is composed of the continents and the ocean floor.

The point with no disturbances in a wave is called a node. Nodes are locations where the amplitude of the wave is zero, resulting in no displacement or disturbance at that point.

yes it will

I am in third grade and this question is a hard one to answer but i spend a week studying nd googleing the hellhell t of this question d got this The moon is at an angle that lines up directly between the earth and the sun ....true story

WHAT MEAN SALT WATER MIXES IN A Ecosysten

The sun/ warmth hit the water and cause evaporation, this puts water particles in the air, we smell this when we are near the ocean. You can smell the particles in the air even though you can't see them.

As far as I know there are no underwater labs. There are aquariums that have created tanks for the study of species, and dive into ocean areas to study life using research ships ( Ballard is a good example of this), but non have built a complex underwater.
