Deep below the surface, there are currents that are controlled by water density, which depends on the temperature and salinity of the water. At mid-latitudes, the atmospheric westerlies induce eastward currents in the ocean while the trade winds are responsible for westward currents in the tropics (Fig. The new findings also suggests that in much of the ocean, lower waters, some 400 meters or so down, would slow as warm upper waters take up more and more of the movement, Xie says.
