They do most of it via simulations, but at the end of the day you've got to test it in the real world if you really want to have faith that it works as advertised. Plus, that's how you get the data that is needed to build the simulations and get them to an acceptable level of fidelity.Jeezus. How many whales did they kill?
I'm not an environmentalist, but it's too bad they can't do these tests with simulations.
When they conduct these kinds of tests, they have observers that are specifically looking for things like whales and such and will delay the test to mitigate the impact. Which is not to say that impacts don't still happen and they compensate the people affected (they don't compensate the family of the dolphin that got blasted to pieces, at least not yet).
