The mysterious sound coming from the deepest point of earth, influenced a group of Scientists to figure out the actual source of this sound. This deepest point of the earth is known as Mariana Trench which is 10,994 meters deep from the Sea-level. The creepy sound from that distance which is even 2.5 km longer than the height of Mount Everest made all the scientists think twice.

A group of researchers from Oregon State University started their mission to find out the actual source of the sound, whether its Biological or Geological. With the help of autonomous seafaring robot aka ‘passive acoustic ocean gliders’ they finally able to determine that the sound was produced by Minke whale, a new type of Baleen whale.

Senior faculty & Lead researcher from Oregon State University, Dr. Sharon Nieukirk said in a statement,“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.”

According to the report by Tcake, these sounds have a wide range of frequencies, ranges between 38 Hz to 8,000 Hz. These kind sounds have plenty of similarities with the sounds produced by the metallic components of the ships in underwater.

Science Alert report says that the same kind of sound was first recorded between autumn 2014 to spring 2015 in the Marianas Trench Marine National Monument. This is the headquarter (246,000 km^2) of Mariana Trench east of Guam, the largest marine protected areas(2,46,608 Km^2) in the world.

Some researchers also claim that the sound does not seem like to be produced by Geological Activities like Earthquake, nor the sound was produced by any biological creature. One the other side, study authors figured out that the sound has so many similarities with the sound of Baleen Whales, which they produce during their mating season in winter.

However, researchers are still not satisfied with the discovery, they will initiate another research until they find out he exact source of this sound.
