Suggestion for Gulf Oil spill containment

Ok, I decided to throw my suggestion up on the web. It isn;t a pretty picture above but you get the idea. The only other addition I would make to this suggestion is that the plastic or heavy canvas needs to be anchored to the Ocean floor and the top of it needs to be connected by those yellow booms they are using now to surround the oil on the surface of the ocean. Add any ideas you have here in the comment link below or comment about mine.
