- Woods Hole Oceanographic Institution discovered a 1949 humpback whale song while digitizing old audio recordings, marking the oldest known whale song recording.
- Peter Tyack said the 1940s ocean soundscape was quieter than today, and the recording offers a rare glimpse of that background.
- Ashley Jester explained the recording was captured on a Gray Audograph disc, a plastic dictation machine disc that survived while many tape recordings deteriorated.
- Roger Payne's discovery of whale song came nearly 20 years after this 1949 recording, highlighting its historical significance.
- NOAA research indicates whales can alter calling behavior in response to human‑made noises, making the quiet 1940s baseline valuable for studying shipping noise impacts.
- Hansen Johnson noted the discovery inspires public curiosity and care for ocean life, though he was not involved in the research.
Why it matters: Marine biologists gain a concrete pre‑industrial acoustic baseline, enabling them to quantify how modern shipping and other anthropogenic sounds have altered humpback whale communication, while conservationists can better target noise‑mitigation measures. This insight can inform regulatory policies on ocean noise and support efforts to preserve whale habitats.
