Deep water currents are formed, when the water become more dense, surface water is cool. and movement of water below the surface. Currents are caused by differences in density, temperature and salinity.
Deep water currents is arise in several ways:
The water along the surface to form wind currents, and deep oceanic currents are caused by differences in temperature and salinity.
They carry cold water from poles to the equator slowly than the surface water currents. Deep currents are prevalent in the oceans.
