Thank you, Mr. Chair.
My question is for Professor Hawboldt.
We've heard from other witnesses about the methods used to try to clean up the oil spill in the gulf—booms to skim the oil, burning in situ, and chemical dispersants—but few people have mentioned something that you did, even just briefly, which is the use of biological methods for cleanup. I've heard references to the use of bacteria. I'm not exactly sure of the biological or chemical process, but can you elaborate on that at all for the committee as to how that would work and what technologies are available in that area?
