What causes the surface ocean currents in the northern hemisphere to deflect to the right, and the currents in the southern hemisphere to deflect to the left? wind coriolis effect gyres gravitational pull

The Coriolis Effect

Explanation:

An ocean gyration occurs when ocean currents from the surface of the northern hemisphere deviate to the right and currents from the southern hemisphere deviate to the left. This effect is caused by the Coriolis effect; planetary vorticity along along with horizontal and vertical friction is what determines the circulation patterns of the wind cycle.
