Ever since I was a kid, ive been fascinated by the ocean and the creatures that inhabit it.
I mean, giant squids, glow in the dark fish octopi that can instantly change their color and texture.
It sounds more like science fiction than reality.
The oceans cover 71% of the earths surface and almost 95% of the oceans have never been seen by human eyes.
Its like an alien planet.
But right here on Earth, every year we learn a little bit more about this mysterious world and its complex ecosystem and that includes how we humans affect that ecosystem.
Now, we did a show about this 174 episodes ago, way back in 2017, but a lot has changed since then, so I wanted to update that episode.
This version has been totally remixed with new narration, new music, and new information.
Youre listening to 20,000 hz.
Im Dallas Taylor.
The sound you just heard is one of the most mysterious underwater sounds we know of.
Its called the Bloop.
It was recorded in 1997 and its unbelievably loud.
The sound was roughly triangulated to be coming from a remote region of the southern Pacific Ocean just west of the tip of South America, America.
The microphones that captured this sound were over 3000 miles away.
Could it be a massive, undiscovered monster from the deep?
Researchers are still discovering new aquatic life every year.
But this sound was several times greater than even the loudest animal in the world, the blue whale.
NOAA, the National oceanic and Atmospheric Administration, now believes it was an ice quake or an iceberg scraping the ocean floor.
Or was it?
