Life on the USNS Impeccable (Score 1)

A few years back I came across this low frequency active sonar technology and realized that the physics associated with it would help make for an interesting side story in a thriller I was writing. The first LFA towed-array sonar ship due to be commissioned in the series was the Impeccable, and so I sketched my guesswork of how the navy might use this vessel in a combat scenario. In the end the writing turned out to be some of the more interesting stuff in the book. It would be hard to imagine how marine animals would not be affected by 230 dB of noise when the beam hits them. On the other hand, it also seems like a technology that the navy couldn't possibly give up. The book is Ninth Day of Creation if anybody wants to see how this LFA sonar works (or possibly does) in practice. I did have to make some conjectures--it's not as though the navy was very forthcoming in its answers to queries about the ships!
