Gulf Stream. The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.
Today, it is understood that the waters feeding into the Gulf Stream begin flowing off the west coast of Northern Africa (map) . There, the Atlantic North Equatorial Current flows from that continent across the Atlantic Ocean.he North Atlantic Current then flows further north and feeds the Norwegian Current and moves the relatively warm water along the west coast of Europe. The rest of the Gulf Stream flows into the Canary Current which moves along the eastern side of the Atlantic Ocean and back south to the equator.
