The strange noise was recorded in the sea around the Antarctic

在南冰洋海域裏,一種詭異鴨叫聲在過去50年裏一直困擾著科學家們。不過據最新一篇發表在《皇家學會報告生物學報》裏的文章稱,此秘密已被破解。請聽 Rebecca Morelle 的報道。

This is the noise that's puzzled scientists for more than 50 years. The mysterious sound can be heard in the winter in the seas around Antarctica and Australia.

It's nicknamed "the bio-duck" by those who think it sounds like a duck quacking.

Now researchers say acoustic recorders attached to two Antarctic minke whales have revealed that the bizarre noise is the animal's underwater chatter.

Scientists say solving this long-standing mystery will help them to learn more about these little-studied mammals and help them to establish where the whales can be found.
