"Bloop"

This sound was repeatedly recorded during summer, 1997 on the Equatorial Pacific Ocean autonomous hydrophone array. The sound rises rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km.  It yields a general location near 50oS; 100oW. The origin of the sound is unknown.  I came across a group called VENTS who conduct research on hypothermal vents in the global oceans and deep seas.  They posted audio clips of unidentified sounds that have been recorded in various times and studies. I appreciate these recordings. It means that humans still have a lot to learn. A lot to understand. Humans still have a lot to learn about design. Design as a whole. What it can do for us and where it can take us.  We should focus more on the unknown, to further our understanding of universal relativity.
