An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon this mean flow, such as breaking waves, wind, Coriolis effect, cabbeling, temperature and salinity differences and tides caused by the gravitational pull of the Moon and the Sun. Depth contours, shoreline configurations and interaction with other currents influence a current's direction and strength.
Ocean currents can flow for great distances, and together they create the great flow of the global conveyor belt which plays a dominant part in determining the climate of many of the Earth’s regions. Perhaps the most striking example is the Gulf Stream, which makes northwest Europe much more temperate than any other region at the same latitude. Another example is Lima, Peru, where the climate is cooler (sub-tropical) than the tropical latitudes in which the area is located, due to the effect of the Humboldt Current.

“Everything that ever walked or crawled on the face of the earth, swum the depths of the ocean or soared through the skies left its imprint here.”
—Robert M. Fresco, and Jack Arnold. Dr. Matt Hastings (John Agar)
“Men perceive that equating love and domestic work is a trap. They fear that to get involved with housework would send them hurtling into the bottomless pit of self-sacrifice that is women’s current caring roles.”
