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.
Surface Ocean Currents An ocean current can be defined as a horizontal movement of seawater at the ocean's surface. Ocean currents are driven by the circulation of wind above surface waters. Frictional stress at the interface between the ocean and the wind causes the water to move in the direction of the wind.Large ocean currents are a response of the atmosphere and ocean to the flow of energy from the tropics to polar regions.n 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.
