Ocean Gyres A gyre is another name for a swirling vortex. Ocean gyres are large swirling bodies of water that are often on the scale of a whole ocean basin or 1000 s of kilometers across (hundreds to thousands of miles across).

Surface Ocean Currents Winds are able to move the top 400 meters of the ocean creating surface ocean currents. Surface ocean currents form large circular patterns called gyres. Gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect. creating surface ocean currents. Near the Earth’s poles, gyres tend to flow in the opposite direction. Surface ocean currents flow in a regular pattern, but they are not all the same. Some currents are deep and narrow. Other currents are shallow and wide.

Ocean current All the world's currents on a continuous ocean map. An ocean current is a continuous movement of ocean water from one place to another. Ocean currents are created by wind, water temperature, salt content, and the gravity of the moon. The current's direction and speed depend on the shoreline and the ocean floor.

- 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.

- Often found in poetic or literary contexts as an alternative to the more familiar circle or spiral, gyre comes via the Latin gyrus from the Greek gyros, meaning ring or circle. Today, gyre is most frequently encountered as an oceanographic term that refers to vast circular systems of ocean currents, such as the North Atlantic Gyre, a system of currents circling clockwise between Europe, Africa, and the Americas.

Currents Global winds are a system of wind patterns distributing warm air unevenly across Earth. If Earth did not rotate, winds would move from the equator to their respective poles. Because Earth rotates, winds appear to be moving east in the Coriolis effect.

- The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity. The great ocean conveyor moves water around the globe. The ocean is not a still body of water. There is constant motion in the ocean in the form of a global ocean conveyor belt.

Boundary current This is accomplished via a decrease in planetary vorticity (since relative vorticity variations are not significant in large ocean circulations), a phenomenon attainable through an equator-wardly directed, interior flow that characterizes the subtropical gyre.

Ocean Currents Surface currents are those found in the upper 400 meters (1,300 feet) of the ocean and make up about 10% of all the water in the ocean. Surface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres.ecause ocean currents circulate water worldwide, they have a significant impact on the movement of energy and moisture between the oceans and the atmosphere. As a result, they are important to the world’s weather.

Pacific Ocean garbage patch worries researchers The sheer quantity of plastic that accumulates in the North Pacific Gyre, a vortex formed by ocean and wind currents and located 1,000 miles off the California coast, has the scientists worried about how it might harm the sea creatures there.

- Ocean water circulates in currents caused mainly by wind friction at the surface (10% of the world ocean. i.e. mostly above the pycnocline). The Coriolis effect and obstruction to flow by continental margins result in surface currents organized into huge circuits known as gyres.he velocity of the Earth's surface increases toward the equator relative to the sideway velocity of the cannon ball (or the air mass of wind). Hence the path will be deflected to the right in the nortern hemisphere and to the left in the southern hemisphere-the Coriolis effect.

Over the counter treatment for Pink Eye, Medication, Pink Eye Contagious? Pink eye treatment consists of over the counter treatment medication and prescription medication. For bacterial infection, there is a an antibiotic that can treat the bacteria. This bacteria is in the form of eye drops or ointments that should be applied to the eyes for some days.If allergy is the reason for pink, then over the counter pink eye treatment includes eye drops like Patanol, which can be effective with just 2 drops in a day.he other medications include antihistamines which are mostly prescribed and not over the counter. Another pink eye drops that is good is Similasan Allergy Relief, an OTC medicine for pink eye that is good but not so effective. OTC medicines for conjunctivitis help in soothing symptoms.

- North Equatorial Current topic. 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.

Ocean gyre In oceanography, a gyre is any large system of circulating ocean currents, particularly those involved with large wind movements. 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.

Ocean gyre These cause frictional surface currents towards the latitude at the center of the gyre. This build-up of water in the center creates flow towards the equator in the upper 1,000 to 2,000 m (3,300 to 6,600 ft) of the ocean, through rather complex dynamics.This flow is returned towards the pole in an intensified western boundary current.he 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.

Ecosystem of the North Pacific Subtropical Gyre The life processes in open-ocean ecosystems are a sink for the atmosphere’s increasing CO2. Gyres make up a large proportion, approximately 75%, of what we refer to as the open ocean, or the area of the ocean that does not consist of coastal areas.he NPSG is the largest of the gyres as well as the largest ecosystem on our planet. Like other subtropical gyres, it has a high-pressure zone in its center.

- With six plastic gyres to clean up in three oceans, we are looking at a minimum international fleet in the region of 300 ZCCs at a probable cost of $0.9 billion dollars (0.736 billion) @ $3 million dollars (2.45 million) a unit-and that is assuming mass production on a not for profit basis.

Ocean Gyres 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. This gyre is full of relatively fresh water as Siberian and Canadian rivers drain into the Beaufort gyre.
