Then how will it be possible to detect the experiment's sound source all the
way across 
the ocean, given that there's so much shipping noise??

So we'll be screwing up their communication. We don't just kill animals, but
torture
them physically, chemically, and mentally by isolating them from one another.
Doesn't it make you proud to be human?
