Ocean Currents are rivers of hot or cold water within the ocean. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon. The depth contours, the shoreline and other movements influence the direction and strength of the movements of water that forms a given current. https://en.wikipedia.org/wiki/Ocean_current Geonames:H.CRNT FTT:597 FTT:598 TGN:21169 Subclasses of this class are to be populated by inference.
