Philippe Cousteau, Jr. Dives into Gulf Oil Spill, Providing Underwater Footage of Pollution

Philippe Cousteau Jr, the grandson of famous marine biologist, Jacques Cousteau, recently scuba dived into an area of the Gulf that was affected by the spill and said it was an "absolute nightmare".

Oil has been spewing into the seas since an April 20 explosion on the Deepwater Horizon rig, just off the Louisiana coast, and the spreading slick is seeping into the state's fragile marshlands.

"I know that my father and grandfather would have been doing this if they were alive and that they would have been just as horrified by what they saw as I was," Cousteau said in an entry on his blog.
