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.
The two factors of primary importance affecting water density are temperature and salinity. These are an important influence on global ocean currents. The process of conve â¦ rgence and divergence also plays an important role on controlling the water density of Oceans. In addition, the density of water increases slightly with increasing pressure and this can become a factor at the tremendous pressure of the deep ocean.
