1949 Audio of Humpback Whale Song Is the Oldest Ever Recorded.

Discovery of the Earliest Humpback Whale Song Recording

According to TSN.ua: A team from the Woods Hole Oceanographic Institution has uncovered what is now considered the oldest known audio recording of a humpback whale's song. Captured on March 7, 1949, near Bermuda, the recording was preserved on a plastic disc. This find pushes back the timeline of documented whale vocalizations by several decades.

The audio was recorded using a Gray Audograph dictation machine—a simple device never intended for underwater use. Yet, aboard the research vessel Atlantis, scientists ingeniously integrated this recorder into an early underwater sound system, making it possible to capture these unique marine sounds. Their resourcefulness highlights the innovative spirit of mid-20th-century oceanographic research.

This discovery underscores the critical role of preserving historical acoustic data for marine biology. With modern analytical tools, researchers can now study these sounds to gain fresh insights into humpback whale behavior, communication, and the ecosystems they inhabit. The recording is expected to be a valuable asset for understanding how whale vocalizations have evolved over time and how they adapt to changing ocean conditions.

Why Preserving Acoustic Data Matters

Unearthing the oldest humpback whale song recording does more than open new scientific frontiers—it reinforces the importance of safeguarding historical records in marine biology. This audio could serve as a baseline for investigating shifts in whale sound patterns over decades and their responses to global environmental changes. Ultimately, the find deepens our grasp of marine biodiversity and supports future conservation efforts for ocean species.
