Ancient Greek straw hat return home with account ofmermaids and sirens . In the sixties , a group of submariner return home from the Southern Ocean with a much odder fib . They had get word the sea quack .
Strange as it might sound , it was not a one - off result and it has even earned itself a quacking name , “ bio duck’s egg ” .
Two decades after submarine personnel first detected the phone , a squad of researchers recorded the mystifying phenomenon – four fusillade of quack - like noises – while creating a soundscape of the South Fiji Basin .
Four years later , in 1986 , Ross Chapman from the University of Victoria joined the undertaking . " We discovered that the data contained a amber mine of Modern information about many variety of sound in the ocean , including sounds from nautical mammalian , " he said in astatement .
refer to the strange quacking randomness , he excuse : " The phone was so quotable , we could n’t believe at first that it was biological . "
However , after talk to colleagues based in Australia , they find similar noises had been detected in other spots tight to New Zealand and Australia .
Chapman now believes what the investigator overheard in 1982 was a conversation between ocean animal : " peradventure they weretalking aboutdinner , perhaps it was parents speak to baby , or maybe they were simply point out on that crazy ship that kept go back and forth towing that long string behind it . "
The “ crazy ship ” he refers to was a vas decked in an acoustic antenna and hydrophones , equipment that enabled the researchers to work out where exactly the strange sound were being made . The resultant role show that there were several “ speakers ” at any one time , though there were no visual sighting that could affirm the identity of the animal doing the “ talk ” .
" The most amazing thing was that when one utterer was let the cat out of the bag , the others were muted , as though they were hear , ” said Chapman . “ Then the first loudspeaker system would stop babble out and listen to responses from others . "
Astudypublished in 2014 suggests the animal responsible for the sound is theAntarctic minke whale . Researchers come to this conclusion after comparing recordings of the “ bio - duck ” with voice made by this mintage of baleen heavyweight , finding convincing similarity between the frequency and number of heart rate .
As for these new Book of Revelation , Chapman introduce his findings as part of the187th coming together of the Acoustical Society of America , which took place recently .
