In the Polar regions, the sea water will have an excess of salt. This is because when sea water freezes, the salt tends to be excluded from the ice crystal matrix and is further dissolved in the sea. So the Polar waters become colder and saltier, therefore of higher density, and tend to sink.
This is the start of a world-wide oceanic conveyor system that has wide implications. The name of this is the Thermohaline system and has an entry in Wikipedia. And some nice maps.

What drives ocean currents?
Ocean currents are primarily driven by a combination of wind, temperature, salinity, and the Earth's rotation (Coriolis effect). The wind plays a significant role in creating surface currents, while differences in temperature and salinity drive deeper currents through processes like thermohaline circulation. The Coriolis effect influences the direction of ocean currents based on the Earth's rotation.
Currents are caused by the Moon's gravity?
currents are generated by the forces acting upon the ocean, such as breaking waves, wind, Coriolis force, temperature, salinity differences and tides caused by the gravitational pull of the Moon and the Sun. Depth contours, shoreline configurations and interaction with other currents influence a current's direction and strength.
How did wind and ocean currents influence the new world?
By using the wind and ocean currents, sailors saved time and effort by letting the wind do the steering. The winds in the Atlantic went in a clockwise circle, and by riding in that circle, they were able to complete journeys much faster, without having to fight winds. http:/www.ucalgary.ca/applied_history/tutor/eurvoya/map.html this link might help some.
Why do most deep currents form near the poles?
Deep currents form near the poles because cold, dense water sinks at the poles due to high salinity and low temperatures. This sinking water sets off a global conveyor belt system known as thermohaline circulation, which drives deep currents towards the equator.
What are 2 abiotic factors of the ocean that are conditions of the environment?
Two abiotic factors of the ocean that are conditions of the environment are temperature and salinity. These factors can affect the distribution of marine species and influence ocean currents and circulation patterns.
How do ocean currents affect plant and animal populations?
By the wind and temperture
How does the wind affect ocean currents?
Wind can impact ocean currents by transferring energy to the surface of the water, causing it to move in the direction of the wind. This creates surface currents that can influence the direction and speed of deeper ocean currents. Strong winds over a large area can lead to the formation of powerful currents, such as the Gulf Stream.
Why does ocean currents and global wind patterns which are caused by convection currents most strongly affect a region's?
Ocean currents and global wind patterns strongly affect a region's climate because they help distribute heat energy around the Earth. Warm ocean currents can increase temperatures in coastal areas, while cold ocean currents can decrease temperatures. Similarly, wind patterns can bring moisture or dry air to a region, affecting its precipitation patterns.
What are 3 things that affect surface ocean currents?
Wind, deflection from land, temperature differences between layers of cold and warm water.
What is the affect of the wind and ocean currents on the tropical rain forest?
the effect is that the currents slowly start killing fish by pushing them onto shore
How do global wind patterns and ocean currents affect a region?
Oh bla bla bla who cares
What are causes of the ocean currents?
The two causes of ocean currents are wind and the rotation of the earth(etc) The wind blows which makes the currents in the water and the rotation of the earth(gravity) makes currents in the ocean currents. Luaye Sharawy
Does ocean currents affect the climat of Tokyo japan?
Yes ocean currents do affect japan.
How do global wind patterns affect ocean surface currents?
Global wind patterns play a crucial role in driving ocean surface currents by transferring energy from the atmosphere to the ocean. As winds blow across the surface of the water, they create friction that pushes the water, forming currents that generally flow in a circular pattern within ocean basins, known as gyres. These currents are influenced by the Coriolis effect, which causes them to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Overall, wind patterns and ocean currents interact to regulate climate, distribute heat, and affect marine ecosystems.
How does ocean currents affect barrier islands?
because of the wind blows the water up onto the barrier island
Ocean currents and global wind patterns which are caused by convection currents most strongly affect a region's?
Ocean currents and global wind patterns, driven by convection currents, most strongly affect a region's climate and weather patterns. These currents influence temperature, precipitation, and seasonal variations by redistributing heat and moisture across the planet. For example, warm ocean currents can lead to milder temperatures along coastlines, while cold currents can create cooler climates. Additionally, wind patterns can impact storm formation and intensity, further shaping regional environmental conditions.
What type of current is caused by wind on the oceans surface?
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.
