As famed Titanic decays, mission will monitor deterioration

The Titanic is disappearing. The iconic ocean liner that was sunk by an iceberg is now slowly succumbing to metal-eating bacteria: holes pervade the wreckage, the crow's nest is already gone and the railing of the ship's iconic bow could collapse at any time.

"The ocean is taking this thing, and we need to document it before it all disappears or becomes unrecognizable," Stockton Rush, president of OceanGate Expeditions, said Friday from a ship headed to the North Atlantic wreck site. The 109-year-old ocean liner is being battered by deep-sea currents and bacteria that consumes hundreds of pounds of iron a day. Some have predicted the ship could vanish in a matter of decades as holes yawn in the hull and sections disintegrate.
