Fascinating. The guy who's been editing the Bloop page at Wikipedia seems to
be a bit beleaguered and has offered to archive up a pile of Bloop-related
pre-icequake material. Perhaps I can write that post-mortem after all.

Subject: Re: I have a new recording of The Bloop
The file itself is 2 megabytes in its original format.
(Un-resampled, so it's not audible without working on it.)
And, since lots of mailboxes have size issues, I've put the information up
(NOTE, 2013, Jan: THE MYSTERY IS SOLVED. This is not a monster. Just sea
ice. And the following sample was PROBABLY NOT the one they had sped-up on
the NOAA site. Also, to everyone else, please stop hotlinking my site.)
Original Sample: 1997253230100_bloop_new.wav
Best I Could Do: mybloop_warbly.mp3
I've attached some spectrographs too to this note.
The noise itself is the more reddish upswing in the yellow parts at the
bottom of the spectrograph, and the arss_spectrograph.jpg is an invertible
conversion of the sample to graphical form that quite a bit more clearly
represents the noise as the lighter patch about 3/4 of the way from left to
The sample itself is:
1997253230100_bloop: RIFF (little-endian) data, WAVE audio, Microsoft PCM,
16 bit, mono 8000 Hz
I was disappointed to learn of the low sampling frequency. It will make
working with it difficult.
I have also attached an mp3 of the noise upsampled and filtered. The warbly
sound is a result of the upsampling, and is not because it is underwater.
If you wish to credit me, please use:
bloopwave (a t) (rune (d o t) ca)
The original arrived in my mailbox on New Year's Eve, Dec 31 2008, from the
NOAA, as a result of communication with:
Christine Patrick (who sent me the WAV itself)
Please also thank the NOAA for being so willing to share their raw data.
They really do credit to the scientific community.
I do not know the name of the scientist who sent along the sample for the PR
folks to forward to me. That nameless scientist gave me a wonderful New
Year's present back then, and I am very grateful.
