World War II's Time Bomb
Ships sunk in Pacific are starting to leak oil

The epic sea battles of World War II ended 60 years ago, but a nagging environmental worry remains. How many ships that went to the bottom still contain oil on board—oil that could leak out?

No one knows exactly how many military and cargo vessels went down. But researchers with the South Pacific Regional Environment Programme have mapped more than 3,800 ships sunk in the Pacific theater of the war. They fear corrosion will cause oil to leak from hundreds of wrecks.

An example: the U.S.S. Mississinewa. On November 20, 1944, the U.S. Navy oil tanker was blown up by a one-man Japanese suicide submarine near the island of Yap. The wreckage was discovered by divers in 2001. That same year the ship, battered by a typhoon, spilled 24,000 gallons (91,000 liters) of oil into a lagoon. A U.S. Navy salvage team patched two leaks, but this year pumped out the remaining 1.8 million gallons (6.8 million liters) of oil—at a cost of about four million dollars.

At this point no one is certain who will inspect hundreds of other oil-laden ships and who will pay for the cleanup.
