Bio-duck (original) (raw)
Bio-duck is a sound recorded in the Southern Ocean, specifically in Antarctic Waters and the West Coast of Australia. It was first reported in 1960 by submarine personnel, who gave the sound its name, associating it with that of a duck. Once dubbed as the “largest still unresolved mysteries of the Southern Ocean”, the origin of the sound remained a mystery for decades until 2014, when it was concluded that the sound originated from Antarctic Minke Whales.

| dbo:abstract | Bio-duck is a sound recorded in the Southern Ocean, specifically in Antarctic Waters and the West Coast of Australia. It was first reported in 1960 by submarine personnel, who gave the sound its name, associating it with that of a duck. Once dubbed as the “largest still unresolved mysteries of the Southern Ocean”, the origin of the sound remained a mystery for decades until 2014, when it was concluded that the sound originated from Antarctic Minke Whales. The recorded sound has a frequency range between 60 Hz to 100 Hz, harmonics up to 1khz, and an interval of 1.6 to 3.1 seconds between each sound. The sound is mainly present during austral winter in the southern ocean, detected off Western Australia and the Antarctic waters. The sound is made near the surface, predominantly before feeding dives. Although the role of the sound remains a mystery, it is suggested that it could play a role in mating. Researchers say that this discovery is significant in estimating seasonal occurrence, migration patterns and abundance of the Antarctic Minke Whales as acoustic research is more cost effective than visual sightings and can be carried out regardless of weather and daylight conditions. Moreover, acoustic research is invaluable since Antarctic Minke Whales inhabit areas of high sea-ice, making conventional ship research challenging. (en) |
