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] The sound serves as a resupply route for cargo ships and airplanes that land on floating ice airstrips near McMurdo Station. The McMurdo seasonal Ice Runway was operated from October to December from the 1950s to the 2010s, then in December the ice breaks up and McMurdo port is opened by an Icebreaker ship and ships can resupply the Antarctic bases.
