The Dome Project In Pictures

With options for containment running low and the environmental disaster widening to more regions of the Gulf Coast, the next step in containment is the use of a 98-ton, four-story structure to stem the leak.

The basic idea of the "Pollution Control Dome" is that it will stop the leak, equalize the pressure and allow for the leaking oil to be pumped to the surface. Although this will do nothing for the oil already leaked, this may substantially cut the spill's environmental impact until other measures can be implemented. Containment domes of this nature have worked in shallow water, but the method has never been tested in water this deep.

What does the dome look like and how is it constructed? Click ahead to see.
