Pensacola, Florida (CNN) -- As the "H2O Below" charter boat leaves the dock and heads into Pensacola Bay, it is chock full of divers. But there's not a single paying client aboard. The boat is carrying a team of local dive industry professionals -- along with an underwater cameraman -- who arranged Wednesday's trip to show that the Gulf oil spill has not affected the prized dive site, the USS Oriskany. "We're going to go out look at the ship, assess the marine life on it and find that there's no oil anywhere around," said Jim Phillips, who owns a dive shop in the area.
