I hope your readers are smart enough to realize this Devon Page has only his own agenda here. I work on a seismic research ship and it has been proven over and over again that seismic testing does not hurt marine life. I have seen whales and dolphins swim a few hundred feet from our air guns. These are intelligent animals and if it was bothering them I am sure they would leave. However, if you wish to save the fish and mammals any possible discomfort at the expense of Human lives then you can blindly follow Mr. Page and his fanatics.
Dolphins and whale probably love seismic ships. The air guns might stun some munchies within a metre or so. Not a speck of scientific evidence that this does them harm, next the creationists are going to sue about fossil hunting!
