5 Creepiest Sounds in the Ocean Ever Recorded

5 Creepiest Sounds in the Ocean Ever Recorded


In November of 2016, the Canadian military began investigating a mysterious sound coming from the bottom of the Arctic. Inuit hunters were reportedly desperate after the unidentified noise caused sea animals to flee the area. The sound has been described by locals as a “pinging” emanating from somewhere on the sea floor in the Hecla and Fury Strait… …but an initial mission by military patrol aircraft conducting an acoustic search failed to detect any anomalies. A Canadian Department of National Defence spokesman admitted that “the cause of the pings remains mired in mystery”… During training in 1984, a Navy diver swore he heard a voice ordering “out!”, but did not find his commander when he surfaced. The only other entity in the tank with him was NOC, a beluga whale trained to retrieve sunken experimental torpedoes. Several more mystery underwater “conversations” were heard until NOC was identified as the source of the human voice. The sounds were not natural, and it is believed NOC was mimicking human speech patterns by inflating his nasal cavity. The phenomenon may also be responsible for other unexplained field reports from divers hearing “screaming children” underwater… In 1991, scientists recording the sounds picked up on the SOSUS underwater surveillance system detected “Upsweep”… …an unidentified sound consisting of a “long train of narrow-band upsweeping sounds of several seconds duration each.” Upsweep is believed to originate from the middle of the Pacific Ocean floor, but its exact location has never been identified. The US Navy had never seen the signal before, and its “overall source level” has been slowly declining since first contact. The sound appears to vary with the seasons, but although some theorize it may be volcano activity, it has never been identified. “Bio-Duck” is the name of a mysterious underwater quacking sound first reported by submarine sailors back in the 1960s. Soviet submarines were especially wary of the noise, as they believed it may have been a new NATO technology targeting their ships. Sonar scans, however, always failed to identify any ships, objects, or creatures in the vicinity that could be a source. Recent research has suggested that it could be from minke whales, but the finding fails to explain the strange Russian encounters… Deep down 7-miles (11 km) beneath the ocean’s surface, the Mariana Trench is anything but quiet. In 2015, scientists lowered a microphone to the bottom of the Challenger Deep and made this eerie recording… …capturing the unearthly moans of a baleen whale just prior to a magnitude 5 earthquake. Light reaches only about 3,280 feet (1 km) underwater, but sound propagates easily and the microphone could even hear the surface… …picking up the propeller noise of a passing ship as well as the fury of a category 4 typhoon that churned overhead.

  1. Secretly I hope that deep in the ocean, there are huge, creepy creatures that are looking like nightmare fuels. I love creepy things, and I love reading about deep-sea creatures, some of them are really disturbing. That's why I love the ocean. 🙂 I hope one day humans will discover a creature that is as huge as "the Bloop".

  2. never have I been fuckin scared of a damn beluga whale until that picture linked with those noises of unholiness made an appearance

  3. Are you serious? Arctic Ping? That HAS to be sonar if I've ever heard it. 100% certain. That's exactly what SONAR sounds like.

  4. the thumbnail is literally a normal beluga whale saying "sup" with it's eyes on the side so you can't see them. they aren't eyeless lmao

  5. What do they mean “To some, it appeared the sources of the Quackers were moving up to 125 mph to circle and chase the submarines”? Wtf goes 125 mph and chases a submarine, like tf

  6. 1:49 that's a captive beluga whale trying to speak English so it can communicate with humans it isn't disturbing or creepy honestly pretty cute and funny

  7. I find the last one incredibly hard to believe, sure there are sounds at the bottom of the ocean but sounds from the surface would certainly not reach

  8. 1. Russian deepwater sub (look at location)
    2. Explained in video
    3. Convection currents from cracks and boundaries in tectonic plates
    4. I don't have an answer but seems relatively explainable, the whale theory seems likely
    5. Explained in video
