a surface current is warmer becasuse it isn't near the bottom of the ocean its near the top so it gets more heat
Thermal Layer
Surface currents are ocean currents that occur near the surface of the ocean and are driven by factors like wind, the Earth's rotation, and surface water density. Deep currents, also known as thermohaline currents, are ocean currents that flow deep beneath the surface and are driven by differences in water temperature and salinity. They are much slower and can extend thousands of meters below the surface.
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.

Deep ocean currents are in the depths of the oceans. Surface current are at the surface, not deep down. Deep ocean currents bring vitamins and nutrients to the shore, surface currents do not. Deep ocean currents are caused by salinity and temperature differences. Surface currents are cause by the force and impact of the wind.
