Seismic acoustic debate on whale strandings.

Ships that survey the oceans and waterways of the world for geological purposes use sound bursts that range from 230 to 255 dB. Cachalots produce high notes at the 235dB and other dolphin species at 229dB. People would argue that this is the cause? The only problem with this theory is that there are approximately 100 vessels worldwide using these sound wave measures to map mining proposals and the like. I lost count at 3,000,000 when estimating the number of the world's toothed whale population. A cachalot can communicate over 10 km and hear another over 100's to 1000's of kilometres. The argument is that the dolphins are more likely to be killing each other with their own clicks than being killed by man made seismic acoustics. Yes, it could be annoying to an animal, like a human having a neighbour playing the drums on a quiet Sunday afternoon, but to kill is never going to happen. As I've noted above these creatures might look vulnerable when washed up on a beach, however, these animals are tough predators capable of amazing biological magic. It takes a force of great magnitude to tip a toothed whale into decline. Like a human, a whale needs to be struck with great force to render concussion or to have prolonged exposure to acoustic waves of an unimaginable range and period. This can only be achieved with energy that seismic ships cannot produce in any way, shape or form. It can only be produced by meteor showers, bolides or airbursts.
