The world’s most elusive whale is also known as 52 Hertz Whale or simply “52” to scientists. This call he made is at the frequency of 52 hertz, which is unusual for a whale as all whales call at around 10-40 hertz. So far, information about the creature is scarce. Unmute the audio icon on the top right side to listen to these eerie sounds.
The Loneliest Whale
This strange whining sound was recorded on March 1, 1999. Julia seems to have originated between Bransfield Straits and Cape Adare, Antarctica. The source of the sound is most likely a large iceberg that has run aground off Antarctica.
In 1997, a low-frequency underwater sound, The Bloop, was recorded by two hydrophones around 4,800 km apart. It was louder than the animals on Earth. Many scientists believe that the sound came from icebergs fracturing and cracking, but the exact source cannot be confirmed.
Recorded in Antarctica’s Ross Sea on March 4, 1997, this mysterious sound feels like a train traversing across a sea bed while tooting its horn. Although still unexplained, researchers believe that it was most likely a moving iceberg that was slowly dragging its keel across the sea floor.
First recorded in 1991, it resembles a siren or howling from an unknown creature. The sound seems to peak in spring and autumn across the Pacific. The origins are still unknown, but a theory indicates it might result from hot lava reacting with cold seawater. The audio you are listening to is at 20x the original speed.
This sound was named so because it slowly decreases in frequency. It was recorded on May 19, 1997, on the eastern equatorial Pacific Ocean autonomous hydrophone array in the Antarctic Peninsula. Researchers presume that an iceberg may have hit the sea floor and slowed to a halt.
This mysterious audio resembles a distant whirring that was captured on July 7, 1997, whose origin is unknown. Researchers believe that the whistle’s surging single frequency is similar to signals recorded during the eruption of underwater volcanoes.
In March 2016, scientists released recordings from the Challenger Deep in the Mariana Trench. Sounds of strange moans, low rumbles, and the occasional high-pitched screech shed light on the deepest world that lies 10.9 km below the Pacific Ocean. Listen to a small clip of the recordings that are supernatural and beautiful.
