The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately 1,300 kilometres (810 mi) from the South Pole.[1]
Captain James Clark Ross discovered the sound in February of 1841 and named it after Lieutenant Archibald McMurdo of HMS Terror.[2] Currently, the sound serves as a resupply route for cargo ships and airplanes that land on floating ice airstrips near McMurdo Station.
