The unsolved Mystery of the Bloop August 04, 2024
In 1997, the NOAA recorded the loudest underwater sound ever. It was so loud, it could be heard for up to 5000 kilometers (~3106 miles) away. The sound, according to some, sounded 'organic', and caused people to theorize that there may be a species of animal residing in our oceans that we have not discovered yet.
The most important part of the solution is taking into account that both the Bloop and the Julia do not sound organic at all. The 'illusion' of the sounds being organic is due to the fact that the sped-up versions get played more than the real-time versions. When listening to the 1X speed versions, you can clearly tell that they don't sound organic in nature at all. So, what are they? Well, that's quite easy to figure out.

All you have to do is look at the spectrograms. The Bloop's spectrogram has clearly visible 'column'. This indicates a sudden spike in sound. Now, we have to think: Which geophysical processes generate sudden sounds? That's right: Ice calving. The sudden cracking of ice from the bigger iceberg causes, obviously, a sudden sound. Furthermore, the estimated location of the source lies somewhere near the western side of the southern tip of South America - which is really cold, so the origin being related to ice is not really far-fetched.

Now, what caused the 'Julia'? That's also quite easy to figure out: The curve which is clearly visible in the spectrogram tells us that whatever caused the sound was probably moving, before suddenly and quickly decelerating. Now, what does that, that is also near Antarctica? A phenomenon called 'seabed gouging by ice'. In short terms, it's when an iceberg collides with the ocean floor, and gets stuck. You can imagine how loud that is.

Lastly, the photo. Its mystique is instantly destroyed once you notice the logo of Surfers against Sewage. Admittedly, it is hard to notice, but it's there. The logo being present tell us that it doesn't depict a real animal, but a fake, animated one.

I accidentally highlighted the wrong section of the article. I meant to highlight the paragraph just below the one that I actually did highlight.

JBZD is not actually a 'news source', at least not by the common definition. Instead, it's more like a general posting board, such as 4chan or Reddit.

I forgot to mention that in the very photo some people associate with the Bloop, you can see the Surfers against Sewage logo.

    Here, WIRED interviewed Robert Dziak, an employee at the NOAA, who confirmed not only that the origin of the Bloop sound was "extremely likely" to have been caused by ice calving or some other similar thing, but also that the theory of the Bloop being caused by an animal was never a serious one. In the interview, Dziak mentions that the main reason the theory of the Bloop being caused by an animal is how it is usually played back.

    I already state this above, but it doesn't appear that this site is a legitimate Polish news source, but more like a general posting site, similar to 4chan, Reddit, or Tumblr.

    This is in German. Additionally, some parts in the video are wrong, such as the location of the source of the "Julia" sound.

    This is the "obscure website" I was talking about in the video.
