It's day 101 of the Disaster in the Gulf. The well's been capped for two weeks, and the water is visibly cleaner, but there's still uncertainty.
Scientists credit the skimming and burning for today's much-smaller, scattered spill, as well as bacteria in the warm water degrading the light crude. But the lingering worry is what you can't see – what BP seldom talks about – underwater oil plumes and their impact on the ecosystem.
One worry is undersea dead zones resulting from oil starving oxygen from the water and its marine life.
Disaster officials are meeting Thursday to discuss the laying off of hundreds of local BP contractors.
