Marine biologists are turning to citizen scientists, sitting at home
in front of their computers, to help unlock the secrets of whale songs.
In Pixar's aquatic adventure Finding Nemo,
Dory, voiced by Ellen DeGeneres, attempts to communicate with a whale
to find the missing title character. She speaks in a loud, slow drawl to
the whale, but when that fails, she says, "Maybe a different dialect."
"We actually know that killer whales do use dialects," marine biologist Peter Tyack tells Weekend Edition host Audie Cornish. Despite the tongue-in-cheek depiction of whale songs, Tyack says the film got it right.
"We
don't know what the sounds mean, but each killer whale family has its
own set of calls, like a dialect in human language," he says.
Tyack, a marine biologist at the University of St. Andrews, is also a coordinator of Whale FM, a new online experiment that's recruiting citizen scientists to study killer and pilot whale calls from around the world.
"The
experiment is the first step in understanding how these whales
communicate," he says. "The first thing we need to know is how to
categorize their calls."
His research team
needs help to sort through almost 15,000 different sound recordings and
group similar ones together. That's where you, the citizen scientist,
come in.
Tyack's team is counting on
whale-song lovers to log on to Whale FM and listen to sounds of various
whales calling to each other.
Tyack says much
about whale communication remains a mystery for scientists, and he
hopes crowdsourcing this new study may lead to some answers.
"We
share a mammalian hearing system with killer whales and we think that
lots of people, just using their own ears, should be able to make good
matches of these calls," he says. "And the more people who decide, the
better sense we get of how reliable their judgments are."
In
the end, Tyack says, one of the major parts of the crowdsourcing
concept of the project is to promote the fact that anyone can take part
in science.
