A 500-pound bomb in the Gulf of Mexico, just one of millions of bits of unexploded munitions in waters off the coast of the U.S.
Lurking (and leaking) beneath the world’s oceans are an estimated 200 million pounds of unexploded and potentially dangerous explosives — from bombs to missiles to mustard gas.
Texas A&M oceanographers William Bryant and Niall Slowey documented two such dumpsites in the Gulf of Mexico recently. They conservatively guess that at least 31 million pounds of bombs can be found not just in the Gulf, but also off the coasts of at least 16 states, from New Jersey to Hawaii.
Thousands of gallon containers of mustard gas lie strewn off the New Jersey coast, for example. And there are a total of seven dumpsites on the Gulf seafloor, each approximately 81 square miles, one at the mouth of the Mississippi River Delta.
