Listen to the Mysterious ‘Alien Call’ From the Depths of Mariana Trench
A sound originating from the deepest parts of the Mariana Trench has experts and scientists spooked. Recorded by the Oregon State University researchers, the sound seems like a chilling alien call that has stunned the researchers.
According to a study published in the Journal of the Acoustical Society of America, the strange sound is probably made by a whale. A statement was made by Neukirk, senior faculty research assistant in marine bioacoustics at Oregon State University. He said, “It’s very distinct, with all these crazy parts. The low-frequency moaning part is typical of baleen whales, and it’s that kind of twangy sound that makes it really unique. We don’t find many new baleen whale calls”

It sounds like bass note reverberating inside a trashcan. The autonomous instruments that record these sounds can dive at a depth of 3,281 feet whereas the Mariana Trench is around 36,000 feet deep. To give you a better perspective, the tallest building in the world – Burj Khalifa is only 2,722 feet high. It was around 3,281 feet under the surface, that the technology picked up this sound.
What does it mean?
This sound – called the biotwang, has perplexed researchers. Even if it is made by whales, what does it even mean? The sound was recorded between fall of 2014 and the spring of 2015. Most of the calls made by baleen whales are mating related and therefore, such calls should be seasonal.
“If it’s a mating call, why are we getting it year round?” Neukirk said in the statement. “That’s a mystery. We need to determine how often the call occurs in summer versus winter, and how widely this call is really distributed.”
The team wishes to make another visit to the Mariana Trench to find their answers. It will help them understand why whales are making such sound, or if it is even whales in the first place.
