Currents Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

- Deep currents form by the differences in the density of the ocean water. Deep currents move by carrying cold water from the poles towards the equators. They flow really slowly…. They may take as long as 1,000 years to flow from the pole to the equator and back again.

Ocean current Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean 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. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them.

- How Does Density Affect Ocean Currents? 2 Mediterranean Seas. Marsigli observed the Bosporus and concluded that there was a surface current that flowed into the Mediterranean Sea from the Black Sea. Marsigli designed an experiment to test his idea. He placing a rope deep enough in the water so that both the surface and deep currents touched it. The rope wouldn’t stay straight but became tangled as if pulled in two directions. Marsigli’s observations led him to believe there was a surface current and a deep undercurrent .. The upper or surface current pulled the top of the rope in the direction of the Mediterranean Sea.

Ocean Currents Currents are caused by winds, gravity, and variations in water density in different parts of the ocean. There are two distinct current systems in the oceans surface circulation, which stirs a relatively thin upper layer of the sea, and deep circulation, which sweeps along the deep-sea floor.hese gyres are made up of currents set in motion by winds and gravity, and steered by the placement of the continents and the rotation of the Earth. Wind is the most important cause of surface currents. When strong, sustained winds blow across the sea, friction drags a thin layer of water into motion.

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. Source(s): Arasan · 9 years ago.

Facts About Ocean Currents The remaining 90 percent of the ocean moves with deep water currents. Deep water is different from surface water in two distinct ways. Deep water is much colder than surface waters, and deep water has a higher salt content. When salty water from a warm region is transported to a region that is cold, it tends to sink.

- Raccoons are typically from 2 to 3 feet long, 9 to 10 inches tall, and weigh between 10 and 30 pounds. Males are typically bigger than females, and individuals living in the north are typically larger than those who live in the south. The back feet of a raccoon are larger than the front feet.n the wild, however, a life span of 2 to 3 years is more typical. Diseases, accidents, and the impacts of large predators (like great horned owls, hawks, eagles, bobcats, wolves, cougars etc) and human hunting and trapping are typical causes of death in a raccoon population.

- 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).

How does salinity affect ocean water? Salinity also has an affect on ocean currents. Near Iceland, if the ocean is not salty enough, the water can't get dense enough to sink. Salinity also has an affect on ocean currents. Near Iceland, if the ocean is not salty enough, the water can't get dense enough to sink. As global warming melts ice in places like greenland, the water gets fresher and sinks slower. this could slow or stop the gulfstream, or perhaps just redirect it.

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. Both move masses of water inland when they reach shallow water and coastlines.

Ocean on the Move: Thermohaline Circulation Cold water, in general, is denser than warm water. Likewise, water with a high salinity is denser than water that contains less salt. Surface ocean currents are primarily driven by winds. Deep ocean currents, on the other hand, are mainly a result of density differences.The thermohaline circulation, often referred to as the ocean's conveyor belt, links major surface and deep water currents in the Atlantic, Indian, Pacific, and Southern Oceans.Multiple mechanisms conspire to increase the density of surface waters at high latitudes.old water, in general, is denser than warm water. Likewise, water with a high salinity is denser than water that contains less salt. Surface ocean currents are primarily driven by winds.

- Bathymetry influences ocean circulation in several ways. First, it steers large-scale ocean. circulation: even relatively small ridges on the sea floor can influence the direction of major. ocean currents. In the deep ocean, ridges serve as solid barriers separating bottom waters in. adjacent ocean basins. Gaps in bathymetry associated with fracture zones play an important.

- 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. There are many factors that determine the strength of a current, as well as the route it will follow. Winds have the most important influence on the flow of currents, but tides, precipitation, evaporation rates, shape of the ocean floor, and inflow from rivers and adjacent seas are also important.

Currents Oceanic currents are driven by several factors. One is the rise and fall of the tides, which is driven by the gravitational attraction of the sun and moon on Earth's oceans. Tides create a current in the oceans, near the shore, and in bays and estuaries along the coast. These are called tidal currents.. Tidal currents are the only type of currents that change in a very regular pattern and can be predicted for future dates. A second factor that drives ocean currents is wind. Winds drive currents that are at or near the ocean's surface.
