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
Resampled+Timeshifted: 1997253230100_bloop_resampled.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 right. 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: Fred Gorell http://explore.noaa.gov/organization/fred-gorell Christine Patrick (who sent me the WAV itself) http://explore.noaa.gov/organization/christine-patrick 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. Sincerely On Monday 04 January 2010, aethan (a t) (bloopwatch (d o t) org) wrote: > Hi.
