A mysterious 52 Hertz signal was first heard in the North Pacific in the late 1980’s. It had the characteristics of a whale call, but it was a higher frequency than what is typical for baleen whales. After years of detecting the signal on hydrophone recordings, scientists have still never seen the whale and are unsure whether it’s a hybrid species or a blue or fin whale that has a problem with its sound production. The 52 Hz whale has often been referred to as “The World’s Loneliest Whale,” because people think that other whales couldn’t understand it’s unique call. Learn more about the 52 Hz whale, underwater communication, whale tracking, and why this whale may not be as lonely as previously assumed from Darlene Ketten of the Woods Hole Oceanographic Institution, Bruce Mate of Oregon State University’s Marine Mammal Institute, and Orla O’Brian.
Bruce Mate will be assisting with the documentary titled, “Finding 52: The Search for the Loneliest Whale in the World.” The search for 52 Hz will begin next fall.
