Despite decades of research and even manned missions to the bottom of the trench , researchers are still discovering new species every year but still have barely scratched the surface. Now, scientists think a mysterious sound coming from the trench in the last few years is a previously unknown call from a dwarf minke whale. An acoustic monitor at the Trench recorded an unknown five-part call coming from the ocean depths, according to a press release. The sound typically lasts between 2. Researchers have dubbed the unidentified sound the Western Pacific Biotwang. According to ScienceAlert , the acoustic monitoring buoy recorded the sound many times between the fall of and the spring of within the Mariana Trench Marine National Monument. While not confirmed, researchers believe it is probably a new vocalization from a dwarf minke whale.

The Western Pacific Biotwang sounds like some funky accent, but it's actually the moniker of a newly discovered whale call. The source of the five-part, preternatural call, which ranges from a low moan to a screechy, metallic tone, has puzzled researchers since it was first recorded in Now, scientists believe minke whales are responsible for the sound. The twangy whale call is described in a paper recently published in the Journal of the Acoustical Society of America. Marine researchers from Cornell and Oregon State universities recorded the call via passive acoustic ocean gliders autonomous vehicles that monitor underwater sounds in the deepest part of the Pacific Ocean, a swath east of Guam and near the Mariana Trench. The call lasts 2. Minke whales are likely producing the unique call, the researchers say in the paper, because it's reminiscent of the "Star Wars" sound made by dwarf minke whales in the Great Barrier Reef. Minke whales are the smallest species of baleen whale , which snag their food by filtering krill and small fish from the water through baleen plates in their mouths. Baleen whales produce regionally specific sounds and mainly call during the winter, often in relation to mating. But the Western Pacific Biotwang was recorded regularly in the fall of and the spring of , indicating it's not used for a specific purpose, such as breeding. The next task for the marine researchers is to find out how often the whales call during the summer versus the winter, and whether this call occurs in other locales. If it's widespread, the Western Pacific Biotwang may be in for a name change. Sounds at the lower end of the human hearing spectrum, around 50 hertz, are akin to a low rumbling. The whooshing of a cymbal is at the higher end, around 20, hertz. Most human speech falls within a few hundred hertz to roughly 8, hertz.

An otherworldly noise that was recorded near the Mariana Trench could be a never-before-heard whale call. Dubbed the "Western Pacific Biotwang," this newly discovered call might be from a minke whale — a type of baleen whale — according to the researchers who documented the vocalization.

A sound in the Mariana Trench notable for its complexity and wide frequency range likely represents the discovery of a new baleen whale call, according to the Oregon State University researchers who recorded and analyzed it. Lasting between 2. We don't find many new baleen whale calls. Recorded via passive acoustic ocean gliders, which are instruments that can travel autonomously for months at a time and dive up to 1, meters, the Western Pacific Biotwang most closely resembles the so-called "Star Wars" sound produced by dwarf minke whales on the Great Barrier Reef off the northeast coast of Australia, researchers say. 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, feet. Minke whales are baleen whales -- meaning they feed by using baleen plates in their mouths to filter krill and small fish from seawater -- and live in most oceans. They produce a collection of regionally specific calls, which in addition to the Star Wars call include "boings" in the North Pacific and low-frequency pulse trains in the Atlantic. But they call frequently, making them good candidates for acoustic studies.
