Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.

How are you doing, mate? I am trying to find out how to say How are you doing, mate? (like in the British way) in French. In America or the other English-speaking countries outside the former British Empire, I think you would replace 'mate' with 'pal' or something along those lines. I've translated it as:  Ça va, mec? But are there any other ways of saying 'mate' in conversational colloquial French? Merci.

Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents. Huge storms move water masses. Underwater earthquakes may trigger devastating tsunamis.

What are the factors influencing ocean current circulation? Surface ocean currents are driven mainly by winds and are affected by seasons.Deep ocean currents are driven mainly by density and temperature gradients. However the most important and fundamental causes for the formation of the ocean currents are solar heating,winds and gravity. 1) Ocean currents are driven by the circulation of wind above surface waters. The water moves in the direction of the wind.

- A pycnocline is the cline or layer where the density gradient (∂ρ/∂z) is greatest within a body of water. An ocean current is generated by the forces such as breaking waves, temperature and salinity differences, wind, Coriolis effect, and tides caused by the gravitational pull of the Moon and the Sun.

- The Atlantic Ocean near Canada is locked in ice in winter but the Atlantic Ocean near England is not. It is thought that the huge temperature difference is due to the Gulf Stream, one of the strongest currents in the ocean, and one of the best studied.(Ben Franklin was one of the first people to map this current.urface water movement takes place in the form of currents. Currents move ocean water horizontally at the ocean's surface. Surface currents are driven mainly by the wind. Other forces such as the Coriolis effect and the location of landmasses do affect surface current patterns.

- What causes ocean currents? Ocean currents result from two processes-the action of wind on the surface of the water, and from variation in water temperature that causes movement-a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale.

Pycnocline A pycnocline is the cline or layer where the density gradient is greatest within a body of water. An ocean current is generated by the forces such as breaking waves, temperature and salinity differences, wind, Coriolis effect, and tides caused by the gravitational pull of the Moon and the Sun. In addition, the physical properties in a pycnocline driven by density gradients also affect the flows and vertical profiles in the ocean. These changes can be connected to the transport of heat, salt, and nutrients through the ocean, and the pycnocline diffusion controls upwelling. Below the mixed layer, a stable density gradient (or pycnocline) separates the upper and lower water, hindering vertical transport. This separation has important biological effects on the ocean and the marine living organisms.

earth science The increased salt concentration increases the surface water's density, causing it to sink. This in turn causes the upwelling of cooler waters that are then warmed by the sun, and the cycle continues. Forces linked to the Earth's rotation also govern the direction of currents. These Coriolis forces cause ocean currents to move clockwise in the Northern Hemisphere, and counterclockwise in the Southern Hemisphere.

- There are, of course, slight regional variations. While the Bahamas are typically quite flat, the westerly sides face large land masses such as Florida, Cuba and beyond that Mexico. Also to the west is the Gulf of Mexico. To the east is the North Atlantic Ocean.

- Surface ocean currents are primarily affected by wind patterns. Trade winds can push water along the top of the ocean and aid in the formation of surface currents. One example of a wind-driven circulation affecting an ocean current is the Gulf Stream.ncreasing carbon dioxide levels in waters and warmer water temperatures impact global ocean circulations, which are one of the primary drivers of weather, temperature, precipitation, and seasons, and therefore affect a variety of aspects of health. 1,2.

Ocean currents Ocean currents, abiotic features of the environment, are continuous and directed movements of ocean water. These currents are on the ocean’s surface and in its depths, flowing both locally and globally. Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis Effect which also influences ocean currents.

Currents Tidal currents are the only type of current affected by the interactions of the Earth, sun, and moon. The moon’s force is much greater than that of the sun because it is 389 times closer to the Earth than the sun is.Tidal currents, just like tides, are affected by the different phases of the moon.idal currents occur in conjunction with the rise and fall of the tide. The vertical motion of the tides near the shore causes the water to move horizontally, creating currents.

Density Creates Currents Convection works in liquids as well as in gases. Ocean currents have several different causes, many of which are due to changes in density. The Gulf Stream is an ocean current that is driven, in part, by convection. It carries warm water from the tropics toward the North Pole.

- The gulfstream is a surface current in the Atlantic ocean that flows northward along the east coast of the U.S. Surface currents are set in motion by the winds. This movement of water in turn effects the circulation in the atmosphere.

- The South Equatorial Currents of the Atlantic and Pacific straddle the equator. Though the Coriolis effect is weak near the equator (and absent at the equator), water moving in the currents on either side of the equator is deflected slightly poleward and replaced by deeper water.

Equatorial Current equatorial current. Either of two oceanic currents (the North and South Equatorial Currents) flowing westward on either side of the equator. The equatorial currents are driven primarily by the easterly trade winds and are separated by a narrower countercurrent flowing eastward along the equator itself. Equatorial currents are relatively shallow, involving the epipelagic zone and part of the mesopelagic zone to depths of less than 500 m (1,640 ft).

Hurricane Andrew In the Bahamas, Andrew brought high tides, hurricane-force winds, and tornadoes, causing widespread structural damage, especially on Cat Cays. About 800 houses were destroyed in the archipelago, and there was substantial damage to the transport, water, sanitation, agriculture, and fishing sectors.everal hours later, the hurricane emerged over the Gulf of Mexico at Category 4 strength, with the Gulf Coast of the United States in its projected path. After weakening slightly, Andrew moved ashore near Morgan City, Louisiana, as low-end Category 3 storm.

Wind Driven Surface Currents: Equatorial Currents Background Source: NOAA GOES-11 & NASA Earth Observatory. The islands of Indonesia mark the boundary between the Indian and Pacific Oceans but do not completely block the flow of seawater between the two ocean basins. Warm, low salinity waters from the Pacific are transported into the Indian Ocean's South Equatorial Current. These waters flow through the many passages between the thousands of Indonesian islands and replenish the large amounts of water removed by evaporation from the northern Indian Ocean.

- Changes in the density set these currents in motion. Some ocean currents are set in motion by the wind. Other ocean currents are created by something. you can’t see or feel. Differences in the density of water can also cause currents to form and move. Density is affected by temperature and salinity. Cold water or water with dissolved salts (higher. salinity) is denser than warm water or water without dissolved salts (low or no salinity).

- Tsunami currents increase strongly in shallow water where weaker corals can be broken by the force of the tsunami. Fish and marine animals are sometimes stranded on the land after they are carried by the currents to shore. The currents also move sand from the beach onto nearby coral reefs, burying low lying corals.

Ocean current An ocean current is a continuous, directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, temperature and salinity differences, while tides are caused by the gravitational pull of the Sun and Moon.cean currents flow for great distances, and together, create the global conveyor belt which plays a dominant role in determining the climate of many of the Earth ’s regions. More specifically, ocean currents influence the temperature of the regions through which they travel.

Currents and Tides El Niño is a phenomenon where an ocean current is reversed, resulting in devastating climate changes from the west coast of South America all the way to Australia. Ocean currents also impact the life cycles of certain marine creatures, such as eels, which relocate thousands of kilometers to spawn based on ocean currents. Tides The ocean's surface rises and falls predictably due to changes in gravitational forces originating from the Moon and the Sun.
