Atlantic Ocean by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate
Strait of Magellan recognized Chilean sovereignty over the Strait of Magellan in the Boundary treaty of 1881 between Chile and Argentina. Argentina had previously claimed all of the strait, or at least the eastern third of it. In 1840 the Pacific Steam Navigation Company was the first to use steamships for commercial traffic in the strait.
