Cap holding as test continues, but crisis still ongoing

GULF OF MEXICO, (NBC) - There are new signs of hope from the floor of the Gulf of Mexico. For more than 24-hours a new containment cap has kept the oil contained, but the success comes with a warning: This crisis is still far from over.

Testing on the cap is only just past the halfway mark, and while the news so far has been good from the gulf floor, little has changed on the surface.

A fleet of underwater cameras help scientists and engineers monitor the situation around the clock, and underwater robots are also scanning the gulf floor searching for any sign of new leaks.

There is a cautious sense of optimism. "It's important that we don't get ahead of ourselves here," President Obama said. "One of problems with having this camera down there that when oil stops gushing, everybody feels we're done and we're not."

While the new containment stack has significantly changed conditions on the floor of the gulf, it hasn't altered the situation on the surface just yet. "It won't change anything," says Gulf Shores, Alabama Mayor Robert Kraft. "We will still continue to pickup oil everyday that it comes in and hope for it to be less and less frequent."

Testing on the cap had delayed work on the ultimate fix, but BP executives now say they have resumed drilling on the primary relief well. Crews could finish that work by the end of the month.
