Deep-sea coral: nicely done, BP

Scientists have found evidence of "dramatic" damage to deep-sea coral near the site of the Gulf oil disaster.

The sites lie seven miles southwest of the well, at a depth of about 4,500 feet, in an area where large plumes of dispersed oil were discovered drifting through the deep ocean last spring in the weeks after the spill.

The discovery of the dead corals offers the strongest evidence so far that oil from the BP well may have harmed marine life in the deep ocean, a concern raised by many biologists soon after the April 20 blowout that caused the spill.
