Description: This is a map of ocean currents over the earth. "In nearly every part of the sea there are slow movements, or currents, of the surface water. The currents move in the general directions of the prevailing winds, and are generally believed to be caused chiefly by them...The trade winds drive the equatorial waters of all the oceans westward, while the prevailing westerly winds urge the sea water eastward in temperate latitudes; and thus on each side of the equator, in both the Atlantic and the Pacific Ocean, the water is thrown into a great whirl or eddy around the region of tropical calms...A branch from the north Atlantic eddy follows the coast of Europe into the Artic Ocean and sweeps around its basin, returning southward near the coast of Greenland...South of the equator in the Indian Ocean, there is a great eddy similar to those in the south Atlantic and Pacific oceans, but north of the equator the currents of the Indian Ocean move generally eastward during half of the year, and generally westward during the other half." &mdsah; Redway, 1898.
