I don't understand this. What, is there an archive out there that has every recorded sound by every single human being and along with has complete information about the recording, and only these 7 clips are not understood?

Partly - the specific ones all seem NOAA originated, which iirr is the American oceanographer group. They along with Navy proper have very vested interests in identifing unusual ocean sounds. But just as you can find parrots that say good morning, given enough fish swimming past enough deep seamicrophones, eventually one ofthem will sound like they are whistling a braoadway tune sorry folks, fun, creepy but in the en…

The sounds are extremely loud and some of them are recurring. Impossible for a fish to cause something like that. The explanation is probably quite prosaic, like ice creeping over Antartica, yet the sounds do carry some significance.

Interesting that most of them are detected in 1997 (4 out of 6 specific ones).

Also, by the same thing: Equatorial Pacific Ocean autonomous hydrophone array. I can't find much about it after ten seconds' worth of googling, but maybe that's when it was constructed?

Looks like it:

"In May, 1996 the array was successfully deployed in the eastern equatorial Pacific to begin long-term monitoring of the East Pacific Rise between 20N and 20S."

I understand the list but I don't know how this stuff gets frontpaged so often in so many places. "Bloop"

"Bloop"

Wow. Maybe it was the loch ness monster on vacation. Or maybe...a bubble. I mean, come on.

The sample is at 16x the original speed. And was heard over 5000km. In other words, not a bubble. Or if it was, it was a bubble worthy of its own wiki page.

SDR (software-defined radio) enthusiasts also found something they can't identify: whistlers. You can see/hear them in this video: http://www.youtube.com/watch?v=0Hv--BR0ddE also briefly addressed here: http://www.youtube.com/watch?v=ZuRcaxpbYCw edit: not on topic, should have refrained from posting as it's a VLF radio phenomenon and not a sound.

It belongs in the same category "unidentified signals". I for one find it pretty interesting.
