Nobody Knows Where the Oil Is Actually Leaking From
USS Arizona sank in nine minutes on December 7, 1941 and has not been touched since. Every day around two litres of fuel oil rise from her hull and spread across Pearl Harbor in a slow dark shimmer that visitors call the tears of the Arizona. What almost nobody realises is that the leak has never been traced. She sits in about 26 feet of water, but beneath that she is buried in roughly another 30 feet of harbour mud, and the lower part of the ship has never been examined by anyone. Scientists cannot reach it, cannot see it, and cannot say which tank is failing. The oil simply arrives at the surface, as it has for 84 years.
What can be measured is the steel above the mud. The National Park Service and the University of Nebraska have run a corrosion research programme on her since 1998, developing a technique that reads the crust of marine growth on the hull to work out how fast the metal underneath is disappearing, without ever cutting into her. The surprise was that corrosion has slowed rather than accelerated. The concretion and marine life covering the hull act as a shield, and the sheltered, low-oxygen harbour water is far gentler on steel than open ocean would be. Structural collapse and a sudden release of the estimated 500,000 gallons still aboard are, by all current indications, not imminent. But the projections only cover what they can measure, and half the ship has been sealed under mud since the morning she went down with over 900 men still inside her.
