It is true that certain frequency sonar does though and that frequency corresponds directly with the shockwaves created by an earthquake on the ocean floor though the range is miniscule in comparison.

Good reasoning until we apply numbers. Junk science reasoning hates numbers. Since an underwater earthquake of a few seconds every so many years creates noise, then new sonar continuously, so much closer to mammal as to have higher dB levels, and being used continuously instead does not do any animal damage. Sorry. Even the US Navy conceded rather quickly that some of the mass mammal stranding were probably a result of their new sonar. That the resulting brain damage to some mammal brains may have been a direct consequence of their new and more powerful sonar. Sorry I have to add some facts and numbers to your speculations.
The real quesiton is not whether noise is causing that problem. Only extremists without facts would deny that. The real question is how much worse will it get, what will be the ultimate consequence if we don't deal with it, and how easily can the problem be solved. After all, more efficient ships should also make less ocean noise. Notice the difference. Asking questions based upon science verses speculation based upon political agenda and junk science reasoning.
The question really has become one of - is this the canary in a coal mine? These same people who would deny a potential ocean noise problem also deny that six of the seven major world fisheries are in serious danger of collapsing or have already failed. It helps to first learn facts before listening to Rush Limbaugh and personal biases.
