re: #24 Dr Lizardo

Yeah, it’d probably just sound like “foomp” and that’s it. And I’m sure underwater mics pick up all manner of weird noises. Hell, remember a few years back, when The Bloop was a thing? Everyone was speculating it was some absolutely enormous marine organism…and it turned out it was just ice calving.

The Navy has deployed sonar listening stations all through the Atlantic and Pacific oceans. Probably the Med as well. They are used in the tracking of Russian, and other nations, subs. I can almost guarantee you that they are capable of distinguishing the sounds of subs, and other man-made noises, from whales farting and icebergs calving. The array in the Pacific was how they detected that the Soviet sub, K-129, had been destroyed and, through geolocation techniques, figured out where it was. That led to a classified attempt to recover the sub miles below the surface. If this sub has imploded, it will be heard.
