Curious ‘citizen scientists’ can now help marine researchers to better understand how killer and pilot whale communicate. Scientific American, in partnership with The Zooniverse team at (Oxford University) and the Citizen Science Alliance (CSA), launched the Whale Song Project (aka Whale FM) to assist in killer whale and pilot whale research conducted by the Woods Hole Oceanographic Institution (WHOI) in Massachusetts and the Sea Mammal Research Unit (SMRU) at the University of St Andrews in Scotland. You can help classifying the sounds that these two species produce just subscribing for free to the Whale FM project. Through the Whale Song Project, people are presented with a whale call and shown where it was recorded on a map; after listening to the whale call and watching its graphical representation, a spectrogram, participants are asked to listen to a series of other calls from the project’s database and to find a match. Have fun!
