In our 2013 field season we managed to apply two suction cup digital acoustic tags to Antarctic minke whales. The recordings made by these tags helped to solve a decades-old mystery of the source of the ‘bio-duck’ sound which has been commonly heard in the Antarctic but never before attributed to an animal. Thanks to analysis of the acoustic records from our tags – case solved – the sounds are produced by minke whales.
