New figures could mean 42 million gallons to more than 100 million gallons of oil have already fouled the Gulf's delicate ecosystem.
Working in the deep sea at the source of the Gulf oil spill is a bit like working in space, say scientists. It's a hard place to get to, a tricky space in which to maneuver, and subject to daunting laws of physics.
