A mysterious, chilling sound had scientists spooked, after it was recorded from the deepest part of the western Pacific ocean - the Mariana Trench.

Lasting around 3.5 seconds, this sound includes moaning noise that hits super-low frequencies at about 38 hertz and then a metallic frequency as high as 8000 hertz. Humans can hear sounds between 20 and 20,000 Hz.

The researchers from Oregon State University’s Hatfield Marine Science Centre believed that, this newly discovered moaning noise - which they dubbed it as the “Western Pacific Biotwang”, might be from a Minke Whale, a type of baleen Whale.

Marine experts sent an autonomous seafaring machine, called as a hydrophone down to the deepest part of the trench. This hydrophone can travel through the sea for months at a time and dive up to 3,281 feet. It's there that it picked up the strange booming sound.

Some experts believe it could be a mating call from a Baleen Whale.

However, the theory is not entirely certain – given that Baleen Whale calls are often related to mating and heard mainly during the winter – and yet the Western Pacific Biotwang was recorded throughout the year.

Sharon Nieukirk, a marine bioacoustics expert at Oregon State said: “If it's a mating call, why are we getting it year round? That's a mystery.” “The sound is very distinct, with all these crazy parts” she added.

The scientists hope that by publishing the noise, other researchers can help identify the “call” so they can get to the bottom of the noise.

The Mariana Trench, the deepest known part of the Earth’s oceans, lies between Japan to the north and Australia to the south and features depths in excess of 36,000 ft.

Here's the sound from the Mariana Trench. Tell us if you can hear something.
