Oldest Humpback Whale Song Recording Authenticated from 1949 Ocean Study

Researchers at the Woods Hole Oceanographic Institution (WHOI) have confirmed the earliest known recording of a humpback whale vocalization, captured in March 1949 near Bermuda. The audio artifact documents the complex songs of the marine mammal, recorded onto a Gray Audograph disc during acoustic experiments conducted aboard the research vessel R/V Atlantis. This expedition, a collaboration with the U.S. Office of Naval Research, was primarily focused on testing sonar systems and measuring explosive volumes, inadvertently preserving a significant piece of natural history.

Marine bioacoustician Peter Tyack noted that this historical recording establishes a vital baseline for the pre-industrial ocean soundscape, which was considerably quieter than the contemporary marine environment. The recovered sounds provide an opportunity to study the acoustic conditions whales experienced before the pervasive increase in human-generated noise, such as that from heavy shipping traffic, which has significantly altered underwater environments. WHOI scientists, including Ashley Jester, director of research data and library services, located the sound last year while digitizing older archival audio materials.

The recording medium itself is notable: the Gray Audograph was an office dictation machine introduced in 1945 that pressed grooves into thin, flexible vinyl discs, differing from the magnetic tape common at the time. This specific disc survived and was uniquely employed for underwater sound documentation, representing a rare example of early ocean listening preserved on this media type. The original scientists used equipment considered advanced for the era but did not catalog the sounds, leaving the recording in storage until its recent rediscovery.

This 1949 documentation predates the popularization of whale song by nearly two decades, which was achieved by scientist Roger Payne through his 1970 album, Songs of the Humpback Whale. Payne’s initial research, which began in the late 1960s after receiving recordings from a Navy engineer monitoring for Soviet submarines near Bermuda, was instrumental in galvanizing the global conservation movement and leading to a moratorium on commercial whaling. The new 1949 recording offers a deeper historical anchor for bioacoustics by providing soundscape context from a time preceding Payne’s initial work.

Contemporary research continues to examine the impact of anthropogenic noise, with data confirming that whales adjust their calling behavior in response to environmental sound levels. The National Oceanic and Atmospheric Administration (NOAA) confirms that ambient noise in busy areas like the Santa Barbara Channel can increase by up to 15 decibels compared to pre-industrial times. WHOI continues its commitment to modern acoustic research, monitoring the ongoing effects of human activity on marine life, building upon the legacy established by these early, fortuitous recordings.
