sheeesh.. after reading that.. that sent shivers up my spine worse than raking fingernails across a chalk board.

Considering the chains as a transmission source, this reminds me of some stuff I worked on long ago along the lines of burst transmitter technology. I agree with the sound file, but I think it should be relative to seastate: higher seastate = more frequent transmissions, lower seastate – less frequent.

Good question. On NB I would say that one would experience intermittent contacts due to the transmission type, of course, but on western BB I would imagine it would display random amplitudes(clanking) then nothing or very faint. Eastern BB would be something to monitor for based on NB signature bearing.

On LWAMI 3.02 – A friend of mine on a team dive told me he heard my sub running aground and it showed up on BB then of course went away, so let's imagine what his bb waterfall looked like registering the intermittent noise? Because of that I think it could be tested how it would show up on BB, and if favorable, somehow implement the same mechanism for chains?

on a custom map.. most definitely as the designer can make a group of clanking.wav with varying amplitudes(soft to very loud) tied to multiple doctrines and scripts to check conditions for range between chains and sub/surface:

Off the top of my head:hmm::

As a platform approaches chains:

IF range <= MAX, start clanking_LOW.wav

IF MED < range < MAX = stop clanking_LOW.wav and run clanking_MED.wav,

IF MIN < range < MED = stop clanking_MED.wav and then run clanking_HIGH.wav.. etc

Depth charges would be a nice addition…

The main question I have still is about the BB signature, other than that, this can be done, I’d say…
