NASA’s mysterious recording of a woman’s deep-sea voice remains unsolved
In 1999, NASA and the National Oceanic and Atmospheric Administration (NOAA) recorded an eerie sound deep under the Pacific Ocean. The agency sent macerated hydrophones into the eastern Pacific Ocean to detect underwater phenomena. A loud noise, described by some as an “underwater voice” similar to the HUM of women is problematic for researchers and the public alike.
Scientists continue to study this acoustic phenomenon to find its true origin. Theories about its origin range from the melting of icebergs to meet Libiwoti in our oceans. Even after 25 years, the source of this mysterious noise remains completely unknown.
Details of “Julia” Recording
On March 1, 1999, NOAA’s hydrophone array captured an eerie sound “Julia”. This underwater microphone works collaboratively to isolate sound sources by analyzing the difference in time arrivals. The sound lasted about 3 minutes and was so powerful that it was detected more than 3,000 kilometers away. The large detection range shows the incredible acoustic power behind this mysterious sound.
NOAA was able to narrow down the source of the sound to a desert area between Bransfield Strait and Cape Adari. Branfield Strait and Cape Adare are located to the southeast, making the origin of the sound challenging to identify. Debates in both scientific and non-scientific debates continue, even 25 years after its discovery.
“Underwater Voice”
Listeners who reviewed the sound described it as a distinctly human quality, a closer look at it “Underwater Voice.” Many compare it to a gentle woman or to a low singing, which got the name “Julia”. The eerie, human quality sets Julia apart from the usual underwater sounds recorded by Marine scientists.
The researchers noted that the acoustic signature resembled the sounds of living creatures but was the longest of any known sea creature. Since there is no definitive theory about the origin of sound, various theories, some fantastic, have sprouted up. Some express the belief that the origin of the sound is more supernatural while others say they are supernatural.

Unsavory Origins
Scientists tried to pinpoint exactly where the sound came from. The region between Bransfield Strait and Cape Adare spans hundreds of kilometers, a vast and inexplicable expanse of ocean. This Antarctic region experiences critical environmental conditions that make research extremely challenging. The remote area contains many underwater features including vertical reefs and deep sea trenches.
The ocean currents in this area create complex acoustic environments that include the identification of the sound source. This makes it more difficult to try and pinpoint the location of the sound source. This difficulty in finding the origin has not only prevented any scientific solution but also sparked wild speculation and conspiracy theories.
Conspiracy theories
The absence of clear scientific answers gives rise to a plethora of conspiracy theories. Some Internet users suggest that the sound was made by an alien spaceship under the waves. Others have imagined ancient sea monsters or alien boats, drawing on stories about nasa satellite images showing underwater shadows.
Claims about the APOLLA 33A5 mission capturing the Apollo 33A5 mission reaching underwater shadows are being circulated around the social media causing internet speculation. These conspiracy theories often arise when scientific explanations remain incomplete or unavailable.
Public reaction and internet debate
People at sites like RedDIT have expressed doubts about the later references to aliens and sea monsters. Many have pointed out that underwater underwater sounds have generated wild Internet speculation before, realizing illegal transparency. One Reddit user noted that even if the post-illegal origins were true, the lack of hostile activity suggests immediate concern.
Internet communities often generate wide-ranging opinions around unexplained scientific matters, especially those involving the remote or inaccessible. Scientists emphasize the importance of evidence-based explanations rather than guesswork.
Scientific hypotheses and the iceberg theory
Scientists, aiming to end the wild speculation on the road of “Under the water,“Proposed natural explanations. The widely accepted hypothesis is that Julia was the sound of a large iceberg running off Antarctica.
Noaa officially stated that it is “the most probable sound source ever known ‘Julia’ is the largest iceberg that has run over Antarctica”. Large icebergs can generate enormous amounts of force when they grind into the ocean or collide with underwater obstacles. This process involves large Ice Masses that create strong motions that transmit through the water like sound waves. Scientists have documented similar events at the base of an iceberg that produce a loud, long-range sound underwater.
Compare other underwater sounds
Julia joins the list of mysterious underwater sounds of unknown origin. Others, such as “Bloop“and”Bio-duck”had experts confused for years before finally many were linked to snow events or animal activity. However, Julia’s eerie human-like personality and the scale of her broadcast make it compelling.
Julia’s unfixed inheritance
Despite logical theories and scientific research, Julia’s underwater voice continues to attract. With ocean exploration around the world still in its infancy, it feels “Julia” Remind us how much remains hidden beneath the waves. Science has only begun to unlock the mysteries of our oceans.
