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.
Weather instruments such as this device installed upon Iceberg B-15A provide scientists a better understanding of Antarctica's impact upon global climate.
