The correct answer is: "marine current"
An ocean current or marine current is a movement of the waters in the oceans and, to a lesser degree, of the more extensive seas. These currents have many causes, mainly the movement of terrestrial rotation (which acts differently and even opposite at the bottom of the ocean and on the surface), as well as the movement of translation of the Earth, the configuration of the coasts and the relative location of the continents. On the other hand, the constant or planetary winds constitute practically a nonexistent cause, since the coincidences between the currents and the planetary winds are due to the fact that they share a common cause, that is, the astronomical movements of the Earth.
