10/ Wind is the primary source of surface ocean currents. The Coriolis effect influences currents. This is due to earth's rotation, currents are deflected to the right of the northern hemisphere and to the left of the southern. As a consequence, gyres flow in opposite directions in the two different hemispheres.
Deep ocean currents are driven by density and temperature gradients. Thermohaline circulation, also known as the ocean's conveyor belt, refers to the deep ocean density-driven ocean basin currents. These currents, which flow under the surface of the ocean and are thus hidden from immediate detection, are called submarine rivers.
