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 Â· 9 years ago.

As wind blows across the sea-surface, part of the wind's momentum is transferred to the ocean, setting up currents. It is therefore clear that ocean currents should show a relationship with the global atmospheric circulation.
