Surface currents in the ocean are the continuous movements of water found at the surface to just a few feet below, these currents are generated by the planet's prevailing winds-which are a direct result of the Sun's radiation and Earth's rotation.
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

In the northern hemisphere, the Coriolis effect causes ocean currents to be deflected to the right. In the southern hemisphere, the Coriolis effect causes ocean currents to be deflected to the left. This deflection leads to the clockwise rotation of ocean currents in the northern hemisphere and counterclockwise rotation in the southern hemisphere.
It is from differing temperatures of air above it that causes currents to flow in the water.
the answer is Coriolis
The gravitation pull on the earth.

Movement of the ocean, or tides are directly related to deep ocean currents. Deep ocean currents are also responsible for the wind that causes the waves to crash into the shore.
