Hey mate, here is your answer :
Speeds of surface currents can reach as high as 250 cm/sec (98 in/sec, or 5.6 mph) a maximum for the Gulf Stream, speeds of deep currents vary from 2 to 10 cm/sec (0.8 to 4 in/sec) or less.
Deep ocean currents are driven by density and temperature gradients. ... Because the movement of deep waterin ocean basins is caused by density-driven forces and gravity, deep waters sink into deep ocean basins at highlatitudes where the temperatures are cold enough to cause the density to increase.

Deep currents are prevalent in the oceans. The currents help in carrying the cold water towards the equator from either ends of the pole.
The velocity of the deep currents are much lesser compared to the surface currents. This causes a high difference in the water density along with temperature variance, and high salinity levels of the water at different locations.
