According to the Washington Times:
"The reports cite computer modeling that indicates 186 whales and dolphins off the East Coast could be killed, and another 155 off the coast of Hawaii and Southern California, AP said.
The injury estimates are even higher.
The report says that off the East Coast, 11,267 sea mammals could suffer serious injuries, and another 1.89 million could have minor injuries, like hearing loss. Off Hawaii and Southern California, 2,039 dolphins and whales may suffer serious injuries, and 1.86 million temporary injuries. Moreover, the testing could dramatically alter the behavior and swimming patterns of millions, AP said.
Twenty million dolphins and whales off the East Coast could change their behavior, as a direct result of the Navy testing. Meanwhile, 7.7 million off the coasts of Hawaii and Southern California could do the same."
