A spectrogram of the 52-hertz signal

The 52-hertz whale is an individual whale of unidentified species, which calls at the very unusual frequency of 52 Hz. This pitch is a much higher frequency than that of the other whale species with migration patterns most closely resembling this whale's[1] – the blue whale (10–39 Hz)[2] or fin whale (20 Hz).[1] It has been detected regularly in many locations since the late 1980s and appears to be the only individual emitting a whale call at this frequency. It has been described as the "world's loneliest whale".[3]


The sonic signature is that of a whale, albeit at a unique frequency. At 52 hertz, it is a little higher than the lowest note on a double bass. The call patterns resemble neither blue nor fin whales, being much higher in frequency, shorter, and more frequent.[4] Blue whales usually vocalize at 10–39 Hz,[2] fin whales at 20 Hz.[1] The 52-hertz calls of this whale are highly variable in their pattern of repetition, duration, and sequence, although they are easily identifiable due to their frequency and characteristic clustering.[5] The calls have deepened slightly to around 49 hertz since 1992, suggesting the whale has grown or matured.[4]

The track of the 52-hertz whale is unrelated to the presence or movement of other whale species.[6] Its movements have been somewhat similar to that of blue whales, but its timing has been more like that of fin whales.[5] It is detected in the Pacific Ocean every year beginning in August–December, and moves out of range of the hydrophones in January–February. It travels as far north as the Aleutian and Kodiak Islands, and as far south as the California coast, swimming between 30 and 70 km each day. Its recorded distance traveled per season has ranged from a low of 708 km to a high of 11,062 km in 2002–03.[7]

Scientists at the Woods Hole Oceanographic Institution have been unable to identify the species of the whale. They speculate that it could be malformed, or possibly a blue whale/fin whale hybrid.[6] The research team has been contacted by deaf people who believe the whale may be deaf.[citation needed]

Whatever biological cause underlies its unusually high frequency voice does not seem to be detrimental to its survival. The fact that the whale has survived and apparently matured indicates it is probably healthy. Still, its unique call is the only one of its kind detected anywhere and there is only one such source per season.[7] Because of this, the animal has been called the loneliest whale in the world.[4][8][9]


The 52-hertz whale was discovered by a team from the Woods Hole Oceanographic Institution. Its call was first detected in 1989, then again in 1990 and 1991.[7] In 1992, following the end of the Cold War, the U.S. Navy partially declassified the recordings and technical specifications of its SOSUS anti-submarine hydrophone arrays, and made SOSUS available for oceanographic research.[5][6] As of 2014, the whale had been detected every year since.[10]

In art[edit]


A feature-length documentary entitled 52: The Search for the Loneliest Whale is in production, shot by Joshua Zeman, the director of Cropsey, and produced by Adrian Grenier. Funded through a Kickstarter campaign, the film was due for release sometime in 2018 but has not been released.[11]

The Loneliest, a short mockumentary film about two women searching for the loneliest whale, was made in April 2014 by Lilian Mehrel, with the Alfred P. Sloan Foundation.[12][13]

Stare Yıldırım's 2018 film My Name is Batlir, Not Butler features the 52-hertz whale as both a character (mostly represented by a photo and voice-over) and as a metaphor for the loneliness of those who are different.[14]

The Taiwanese movie 52Hz, I Love You's title is inspired by the whale, using it as a metaphor for the loneliness experienced when looking for love.

Montreal-based saxophone player and composer Colin Stetson's 2013 album New History Warfare Vol. 3: To See More Light included a song entitled "Part of Me Apart From You". Though not explicitly written about the 52-hertz whale, when first performing the song live, he has remarked on at least several occasions that the story of the "loneliest whale" resonated deeply with his composition. "This whale is alone in a large body of water, swimming, singing its song, calling for a likeness it will never find," he said by way of introducing the song at a performance at Toronto's Great Hall on 19 May 2013. "When I play this song, I can't help but think about this whale, who right at this very minute is singing alone."[15]

South Korean group BTS's 2015 album The Most Beautiful Moment in Life, Part 2's fourth track, "Whalien 52", explicitly uses the 52-hertz whale as a metaphor for the alienation from others often felt by adolescents.[16]

The English folk duo Kathryn Roberts and Sean Lakeman included the song "52 Hertz" on their 2015 album Tomorrow Will Follow Today. The song is about the whale and includes the line, "52 Hertz, 52 Hertz, I'm singing a love song that no-one can hear" in the chorus.[17]

In 2018, American singer Chrysta Bell released a song "52 Hz" inspired by the whale, in which she sings "52 Hertz I'm all alone, 52 Hertz on my hydrophone".[18]

"The Loneliest Mix" is an audio project by Mike Ambs, inspired by the 52-hertz whale. The project uses the 52-hertz song at real-time speed.[19]
