The Search for 52 Print

The 52-hertz whale is an individual whale of unidentified species which calls at the unusual frequency of 52 Hz. This pitch is a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's – the blue whale (10–39 Hz) or fin whale (20 Hz). Its call 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. However, the whale itself has never been sighted, it has only been heard via hydrophones. It has been described as the "world's loneliest whale”. Characteristics: 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. Blue whales usually vocalize at 10–39 Hz, fin whales at 20 Hz. 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. The calls have deepened slightly to around 50 hertz since 1992, suggesting the whale has grown or matured. The migration track of the 52-hertz whale is unrelated to the presence or movement of other whale species. Its movements have been somewhat similar to that of blue whales, but its timing has been more like that of fin whales. 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. 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 a blue whale hybrid. The research team is often contacted by deaf people who wonder whether the whale may also be deaf. 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. Because of this, the animal has been called the loneliest whale in the world. History: 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. 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. As of 2014, the whale had been detected every year since. The Loneliest Whale: The Search for 52 is a 2021 American documentary film, directed, written, and produced by Joshua Zeman. Leonardo DiCaprio and Adrian Grenier serve as executive producers. The film follows a group of scientists in search of the 52-hertz whale, a whale which is believed to have spent its life in solitude, calling out at a frequency different from any other whale. It was commercially released in theaters and on video on demand by Bleecker Street on July 9, 2021. Plot: The film follows Zeman and a team of oceanographers and scientists on a quest to find the "52-hertz whale," which scientists believe has spent its entire life in solitude calling out at a frequency that is different from any other whale. Zeman also explores the Cold War science of submarine warfare that led to the originally discovery of the 52-hertz whale, the negative impact of whaling, the release and reception of the Songs of the Humpback Whale record, the detrimental effects of ocean noise on whale and their communication, and how society’s dependence on technology can lead to feelings of isolation among people.
