McMurdo Sound

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.

Captain James Clark Ross discovered the sound in February of 1841 and named it after Lieutenant Archibald McMurdo of HMS Terror. Currently, the sound serves as a resupply route for cargo ships and airplanes that land on floating ice airstrips near McMurdo Station.
