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
Atlantic Europe still is a cultural continuum in Atlantic Europe, forming a cultural unit which has its roots in prehistoric times but remained until today mostly thanks to sea trade. Geographers also mention the influence of the natural environment in the construction of a similar cultural landscape along the western European coasts. Some of the first geographers to consider this idea of Atlantic Europe were Otero Pedrayo and Orlando Ribeiro. Pedrayo stated in his studies about Galicia that this territory was marked by a strong "Atlantic character", not Mediterranean, despite the fact of being part of a Mediterranean state (Spain). On the
