A 1949 humpback whale song off Bermuda is now the oldest known whale vocalization, found in a preserved plastic disc.
A humpback whale song recorded in March 1949 off Bermuda has been identified as the oldest known whale vocalization, discovered by Woods Hole Oceanographic Institution researchers during a digitization project.
Captured unintentionally during sonar tests using a Gray Audograph, the sound was preserved on a durable plastic disc—unlike fragile tapes from that era.
The recording offers a rare glimpse into the ocean’s quieter 1940s soundscape, providing a baseline for studying how modern human-made noise affects whale communication, navigation, and behavior.
