The US navy set off a massive explosion last week, detonating a 40,000lb blast as part of a test to determine whether its newest aircraft carrier, the USS Gerald Ford, is ready for war. The test, known as a full ship shock trial, is just the first of three planned blasts over the coming months. But the amount of explosive used – 40,000 lbs – is enough to have outsized effects on any marine life in the area, said Michael Jasny, who directs the Natural Resources Defense Council’s Marine Mammal Protection Project. “The navy’s own modeling indicates that some smaller species of marine mammals would be expected to die within 1-2km of the blast, and that some marine mammal species would suffer injury including hearing loss out to 10km of the blast. That gives some sense of the power of the explosives we are talking about,” Jasny said. “We don’t know how conscientiously the blast site was chosen, and we don’t know how effective the monitoring was before the detonation, so it’s hard to put a great deal of faith in the safety of marine life.” The area is home to populations of dolphin and small whales at this time of year, and Jasny says that’s worrisome because as a general rule, smaller animals are more vulnerable to blast injury. “A large whale might need to be within a few hundred meters of the blast to die, while a small mammal could be a couple of kilometers away,” he said, adding that even if the animals survive, loss of hearing is a significant problem for mammals who make their living in the ocean.
