One day I was walking my dog next to a frozen lake... and suddenly a very deep, very loud sound "appears". I wouldn't say that I "hear" it... to be more exact... I would say that I "felt" it... I felt it inside me and everywhere. Of course that left me in shock... I had never heard anything like this in my life... and I have never heard it again. I am not able to express the depth of that sound. It was like being in a movie. I didn't imagine it because my dog listen it too. I'm not sure what I heard... but I think what happened is that the lake was thawing... and I think what produced the sound was the entire surface of the lake descending a few cm and reverberating like a gigantic drum.

In the 1960s, the US military set up a huge underwater surveillance system to track submarines, ours and theirs. In 1968 a soviet submarine had an onboard explosion which sank the submarine. The US knew precisely where the sub was located, it turned out the soviets knew nothing. The Glomar Explorer was build ostensibly to explore for undersea mining, but actually was to recover the missing soviet submarine.

@rodchallis8031

Back in the before times, I used to read the colour comics section of our weekend paper. On the back page there was a feature dedicated to sciency stuff. The Glomar Explorer was featured and it always stuck in my head. Knowing how security agencies use P.R. companies etc., to plant "news" from time to time, after I found out the true purpose of the Glomar Explorer, I wondered if that feature was a CIA plant.

When looking for a solution to mysterious underwater sounds, the best method is to use Occam's Razor; which in this case leads to the answer that it's an interdimensional city phasing back into our spacetime and the pressure of the displaced water causes the noise. 😛

Hello Joe! I am really curious about the sounds of the ocean during the pandemic when all the shipping traffic was quiet. I tried to attempt to research this but hit a bunch of dead ends.

This is a very entertaining and thoughtful video. Thank you! One helpful grammar tip: Use "farther" for distance, as in "Sound waves travel farther in water than they do in air." Use "further" for just about everything else. As in: "These night courses will further my criminology education." Or "The further I get into this story, the more confused I become." All good wishes.

Obviously "The Whistle" is easily explained. Clearly a cephalopod, dreaming of betters days while watching _Alien_ unplugged its hydro-headphones before reducing the amplifier volume. That's why the hydrophone recorded several moments of the _LV-426_ windstorm.

Very curious and interesting, as per usual! I have a question though: a lot of the sounds you mention were first recorded in 1997. Was that the year the array was built across the sea floor or was that just a particularly terrifying period for marine science? Keep up the good work!

Lots of big stuff coming in April. ;)

the thing I rarely see mentioned whenever the recording is talked about but is in my opinion very important to how it could be perceived is that it (and most other of these sea noises) have been sped up and pitched up by a lot (the bloop is 16 times), the original recording lasted about a minute and ranged from around 10hz to 50hz, which most speakers are incapable of reproducing, half of it is outside the human hearing range, and the rest is just barely within it, if it were possible to perfectly reproduce it would likely just sound/feel like a rumble at it's real pitch/tempo (if played at a safe volume)

never change. I always love your side comments, noises, and made up words.

There were also a few quite serious episodes like a small Swedish boat almost being shot at when they tried to get close to the stern of the submarine to do clandestine measurements of possible radiation, indicating torpedos equipped with nuclear warheads.
