I think the most striking thing about the Flannan Isle that you didn't cover, is the journal entries showing how the men grew more and more erratic.

[@simonzinc-trumpetharris852]

Only the journal entries were not real. They were an embellishment added by Conan Doyle.

I can't help but wonder if the game "No One lives Under the Lighthouse" is based off this mystery.

[@Jade_holloway]

@@simonzinc-trumpetharris852 it wasn't Conan Doyle, it was the Mary Celeste that he wrote about.

[@Veladus]

That's because the journals are fiction. They don't appear in the early versions of the story, some asshole added them later to make it interesting.

[@mosesbrown4126]

At this point, we have confirmed the existence of insane rogue waves, which would completely explain everything, including the one side of the island being devastated and swept clear.

2 - the microphones arent there to pick up mysterious sounds they are there to monitor the ocean to teach us about our disturbance of unspoiled marine environments, even those more than 2km deep. The microphones just happened to also pick up this sound too. theres still no scientific consensus based on the bloop, the main reason there may seem to be is that people can tend to fixate on this sort of phenomena while other folks get on with their lives. but the best reasonable explanation is a large expulsion of gas from earths core coming to the surface from a deep sea vent

[@respectableindividual4593]

Nope sorry bro it was a really big and cool monster actually

[@chubbs2962]

So the last sound is air leaking out of a solid block of rock or bedrock or some other sort of dense earthen material, that is being subjected to a rapid change of pressure or position thereby allowing a steady "drip" of gas to be released in a sort of rhythmic pattern. To scale it down, drop a bunch of different rocks of at least baseball sized, into a bucket of warm water and let it settle for a couple min, find a quiet place and listen to what sounds come from the bucket.

[@hollyw17330od]

My cousin grew up in oakville and was there during the time of the unknown substance raining down. We used to swim at a local rock quarry in town and i experienced some bad physical reactions several times after swimming. Eventually the lake was closed due to radioactivity i often wonder if the contamination came from the gelatinous substance entering the ground and ground water. Its such a tiny town no one cared about the residents or getting answers for them besides a small unsolved mysteries story. Nowadays i see this story on KZbin a lot & wonder if this platform existed in the 90s if we would have got a real explanation.

[@SZPWS1777]

The 'Bloop' sound, was nothing more than a guy named 'Reggie,' who unexpectedly fell off of a fishing boat while on vacation. Reggie was a large man, and was known for constantly farting quite loudly. The startling event of him falling into the ocean, was enough for him to let loose the biggest underwater toot ever heard. Now, it could be said that this is all conjecture. But I assure you, a well-made burrito can do strange things to the human body.

Has no one noticed that "Bloop" and "Upsweep" are coming from the same area? "Upsweep" sounds like an alert siren blaring underwater. Could some underwater base have breached, and the alerts going out and no one there to shut it off?

[@farmer_joe_]

An underwater base with speakers powerful enough to literally shred a person who stands too close when it goes off? What makes the bloop so weird is that it had to come from some massive power that we've seen no trace of.

Their job (and this was during the cold war) was to just sit with headphones on and listen to north Atlantic hydrophones.. ALL. DAY. God that'd be so creepy.

20:48 Heh. Slowed down it sounded like a passing vehicle. Played at normal speed sounds like a noisy flying plane, or the kind of sounds films and games would play for blizzards. I like this vid since it's not pushing some kind of mystery, and just telling it as is, with some musings. Many vids concerning 'mysteries' try to push some kind of unnatural, or suipernatural element to them. Those vids are super annoying to listen to.

Glad you enjoyed!

[@thalastianjorus]

The "Upsweep" sounds like an alarm going off. A siren styled alarm. If it were a nuclear powered vessel that's somehow gotten stuck, and never had a hull breach... Then its power supply could run for decades. Especially if all it is powering is an alarm, and potentially lights.

The thing about "logical explanations" is that people try to mark unexplained with something primitive that they can explain. But it is self-deception. Its just too hard for many to accept that there are things beyond their knowledge to be expanded.

@@Huemanish Yeah but a bloop is more of a sound that would be created by some creature, ice sheets cracking would sound more like a crashing sound, the intensity of that probably wouldnt be able create such intensity either, to create a bloop sound over those ocean scanners takes massive decibel intensity, go brush up on the bloop videos and informational contributions, and youll see what im saying.

youre research is dated the airbirst has been ruled out as impossible due to no extra-terrestrial anomalies being found from soil or within any of the still remaining trees found on site. the explaination as to what happened is still a mystery, but the absence of lingering radiation also rules out a nuclear blast, the best theory presently is a kaiper belt or similar ice chunk. all things aside it is one of the most strangest things out there that we really have very little idea about
