Vocabulary Ocean Current Coriolis Effect Rip Current Upwelling Major Ocean Currents An Ocean Current is a large volume of water flowing in a certain direction Winddriven currents are called surface currents. Early ocean studies. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally..
