November 7, 2016 — A group of Falmouth-based researchers has gained new insight into the songs of the humpback whale.
When a whale sings, physical vibrations can be felt around the animal. A team of researchers from the Woods Hole Oceanographic Institution found that these vibrations, known as particle velocity, can be felt much farther away than originally thought.
“Particle velocity is kind of the long bass that you feel when a car is approaching you. You can hear the sound far away, but you can also feel the vibration,” said Aran Mooney, a Woods Hole biologist. “But sound doesn’t travel as well in air as it does in water.”
In a paper published Wednesday in the journal Biology Letters, the Woods Hole team detailed their findings from studying a group of humpback whales off the coast of Maui. Mooney said they measured vibrations from about 200 meters away from the whales, but believe they could be felt as far as one kilometer away.
