The boundary between the Atlantic and Pacific Oceans is sometimes taken to be a line drawn from Cape Horn to Snow Island 130 kilometres (80.8 mi) north of mainland Antarctica). Alternatively the meridian that passes through Cape Horn may be taken as the boundary. Both boundaries lie entirely within the Drake Passage.
