If it quacks like a duck, it may be almost like a whale

Mystery of 'ocean quack sound' solved

The mystery of a bizarre quacking sound heard in the ocean has finally been solved, scientists report.

The noise - nicknamed "the bio-duck" - appears in the winter and spring in the Southern Ocean. However, its source has baffled researchers for decades.

Now acoustic recorders have revealed that the sound is in fact the underwater chatter of the Antarctic minke whale.
...
In 2013, acoustic recorders were attached to two of the marine mammals and recorded the whales making the strange noise.

Glad someone thought to include it in an article which will be read internationally.

From the article:

Dr Risch said: "Identifying their sounds will allow us to use passive acoustic monitoring to study this species.

No reason to kill them, and rip them to shreds, and pack them in cans or frozen packages to get to the bottom of it!

Good for these enlightened scientists!
