Mystery of the ocean quack is solved For several decades, scientists have puzzled over what was producing a bizarre quacking sound that could be heard in the Southern Ocean during winter and spring. And now scientists from the US National Oceanic and Atmospheric Administration (NOAA) believe they have found the source. It appears that the “bio-duck” noise is actually just the underwater chatter of the Antarctic Minke whale, reported the BBC. Lead researcher Denise Risch, form the NOAA, said: It was hard to find the source of the signal. Over the years there have been several suggestions... but no-one was able to really show this species was producing the sound until now.
