Scientists track giant whales by their earthshaking calls

fin whale diagramScientists use seismometers on the ocean floor to monitor small earthquakes. But these seismometers detect more than earthquakes, they pick up the deep tones of the calls of fin whales — far more whale calls, in fact, than earthquakes.  Fin whales produce some of the loudest noises in the animal kingdom. But they haven't been studied much, so scientists are learning to use the whale calls recorded by their seismic equipment to learn more about the behavior of the fin whales. You can learn more about this amazing application of data from one scientific discipline to another in a May 11, 2013 article in the Seattle Times by Sandi Doughton: Scientists track giant whales by their earthshaking calls. That online article also contains audio of whale calls off Vancouver Island.
