- Eastern boundary currents are relatively shallow, broad, and slow-flowing. Western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west si…de of ocean basins due to western intensification. Making the world better, one answer at a time. similarity is currents form gyres. difference is currents are any movement of water in one specific direction and gyres are circular patterns of water. similarity is currents form gyres. difference is currents are any movement of water in one specific direction and gyres are circular patterns of water.

Ocean Gyres Ocean gyres dominate the open ocean and represent the long-term average pattern of ocean surface currents. Ocean gyres in the Northern hemisphere rotate clockwise and gyres in the Southern hemisphere rotate counter-clockwise due to the Coriolis effect. The major gyres of the ocean include: North Atlantic, South Atlantic, North Pacific, South Pacific and Indian Ocean gyres. A simplistic drawing of those can be seen on this page. Many other smaller gyres exist in the ocean too. One such smaller gyre is the Beaufort gyre found in the Arctic Ocean. The Beaufort gyre is a huge vortex of water being driven by strong winds that force currents in a clockwise direction

(q). Surface and Subsurface Ocean Currents On either side of the equator, in all ocean basins, there are two west flowing currents: the North and South Equatorial (Figure 8q-1) . These currents flow between 3 and 6 kilometers per day and usually extend 100 to 200 meters in depth below the ocean surface.n either side of the equator, in all ocean basins, there are two west flowing currents: the North and South Equatorial (Figure 8q-1) .

- Ocean gyre. A gyre is a large system of ocean currents moving in a circle. Gyres are caused by the Coriolis effect. Because the Earth is rotating, ocean currents in the northern hemisphere tend to move in a clockwise direction and currents in the southern hemisphere in an anti-clockwise direction.

North Equatorial Current The westward surface flow at the equator in both oceans is part of the South Equatorial Current . See also Ocean current Oceanic gyres Physical oceanography The North Equatorial Current is a significant Pacific and Atlantic Ocean current that flows east-to-west between about 10° north and 20° north . It is the southern side of a clockwise subtropical gyre. Despite its name, the North Equatorial Current is not connected to the equator.

Upwelling The split in this system occurs at Point Conception, California due to weak upwelling in the South and strong upwelling in the north. The Canary Current is an eastern boundary current of the North Atlantic Gyre and is also separated due to the presence of the Canary Islands.

Marine Biodiversity Wiki Surface Ocean Currents 1 2 3 4. 1  Winds Drive Surface Ocean Currents. 2  Global winds drag on the water’s surface, causing it to move and build up in the direction that the wind is blowing. 3  There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres.

Thermal Energy in the Ocean Because they are wind-driven, the gyres are not very deep. Only about 100 meters or so of the ocean surface moves in the gyre, but this is a great deal of water. The water flow of the north Atlantic gyre, for example, is larger than the total flow of all the Earth’s rivers.

- The Gulf Stream, located along the eastern coast of the United States, is a fast, intense current known as a western-boundary current. These currents are located on the western side of every ocean basin. The Gulf Stream is a result of the wind pattern acting on most of the North Atlantic Ocean. The combination of the Trade Winds (10°- 25°N) blowing to the west and the Westerlies (35°- 55°N) blowing to the east cause the North Atlantic to rotate clockwise.

Wind Driven Surface Currents: Western Boundary Currents Background Surface currents located on the western side of the subtropical gyres, so-called western boundary currents, are faster than their eastern counterparts. In fact, they are among the fastest surface currents in the ocean.

Atlantic Ocean A western boundary current, the Gulf Stream flows roughly parallel to the east coast of the United States, picks up more water, and reaches about 80 million cubic meters per second at Cape Hatteras, off the coast of South Carolina.

- The major driving force of surface currents is the wind. Friction between the wind and the water sets these currents in motion. The winds that drive surface currents are the Westerlies that blow west to east at 40 degrees to 50 degrees latitude and the trade winds that blow east to west at 20 degrees latitude.he major driving force of surface currents is the wind.

- This closes the loop of the clockwise-going Atlantic gyre. The sun causes the Gulf Stream by heating the Earth s equator more than its poles. The Gulf Stream helps to redistribute the heat by carrying warm waters towards the North Pole.

What is a gyre? Subtropical gyres are another type; their centers are high pressure zones because of the movement of the westerly winds in the northern side and easterly winds in the southern side. Another type of gyre is the subpolar gyre; these form at high latitudes. Gyres are believed to contain a lot of waste in them.They contain a lot of plastic, chemical compounds, and other non-biodegradable waste products.yre is an important term in oceanography. Gyres can be caused by a number of reasons; one of them is the Coriolis force. The coriolis effect is caused because of the rotation of the earth. This effect causes a number of cyclones on the earth’s surface.

What is the Sargasso Sea? The Gulf Stream establishes the Sargasso Sea’s western boundary, while the Sea is further defined to the north by the North Atlantic Current, to the east by the Canary Current, and to the south by the North Atlantic Equatorial Current.

Wind Driven Surface Currents: Upwelling and Downwelling Background Upwelling is most common along the west coast of continents (eastern sides of ocean basins). In the Northern Hemisphere, upwelling occurs along west coasts (e.g., coasts of California, Northwest Africa) when winds blow from the north (causing Ekman transport of surface water away from the shore).

- Gyre, in oceanography and climatology, a vast circular system made up of ocean currents that spirals about a central point. The most prominent are the subtropical gyres, which ring subtropical high-pressure systems, and the subpolar gyres, which enclose areas of low atmospheric pressure over the oceans.

- There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).

- Western boundary currents are also among the fastest non-tidal ocean currents on Earth, reaching speeds of more than five miles per hour (2.5 meters per second) and containing as much as 100 times the combined flow of the world's rivers.he colder eastern boundary currents, which flow from the high latitudes toward the equator, are the slowest and most diffuse currents around the gyre. As they reach the equator, they turn west and pick up speed, driven by the trade winds and heat from the tropical sun.

- Gyres are caused by the Coriolis effect; planetary vorticity along with horizontal and vertical friction, determine the circulation patterns from the wind stress curl . The term gyre can be used to refer to any type of vortex in the air or the sea, even one that is man-made, but it is most commonly used in oceanography to refer to the major ocean systems.

- A gyre’s currents also cause floating debris to slowly drift towards the center of the ocean, forming large patches of floating trash. This can be a hazard to marine life and, as the chemicals in the plastics enter the food chain, of concern to humans, as well.

Wind Driven Surface Currents: Equatorial Currents Background The trade winds of the two hemispheres converge in a narrow east-west zone located near the equator known as the Intertropical Convergence Zone (ITCZ). The ITCZ is an important component of the planetary-scale atmospheric circulation that is particularly well defined over the tropical ocean.

- The Brazil current as represented by the Mariano Global Surface Velocity Analysis (MGSVA). The Brazil current is the western boundary current of the South Atlantic subtropical gyre. It transports warm water polewards. Near 22 S, the Brazil current splits; one component flows eastward and the other component hugs the coast and flows toward the southwest and interacts with the colder Malvinas Current.
