picture today from plaquemines parish officials which show oil still on the surface an barataria bay. i think they're annoyed, worried that the coast guard is going to be pulling out too quickly. do we know under water what's happening? there was all that talk of those plumes and oil being under the water. is that still there? is that going to just dissipate harmlessly or is that going to affect the food chain? >> well, we certainly hope it will dissipate. my projection is that it will dissipate. the oil -- the plumes -- underwater plumes are dilute concentrations of dispersed oil. now, the more dilute it is the less damage it will incur and it's starting to be deteriorated by the bacteria as well as the ocean current. i don't anticipate there will be massive damage. the damage is both toxicological and the reduction in the oxygen content of the water column.
