President Obama called the cap on the gulf oil leak "good news" today, but he cautioned that the job of ending the massive oil leak is not yet complete.
"There were a lot of reports coming out in the media that seemed to indicate, 'Well, maybe this thing is done,'" he said . "We won't be done until we actually know that we've killed the well and that we have a permanent solution in place," he said in the White House Rose Garden before heading off to a Maine vacation.
The president was referring to BP's successful attempt -- so far -- to place a tight cap on the busted oil well and for the first time in 87 days prevent the underwater gusher from pouring into the gulf. BP called Thursday's success a test to see if the device will withstand the pressure of the surging oil, or whether the oil is now leaking out somewhere else in the ocean bedrock.
"It's important that we don't get ahead of ourselves here," Obama said today. "You know, one of the problems with having this camera down there is that when the oil stops gushing, everybody feels like we're done. And we're not."
He said the well still has to be permanently plugged and there is the massive clean-up of areas polluted by the spill, which Obama said needs "better coordination on the ground along the shorelines."
"But we are making steady progress," the president said, "and I think the American people should take some heart in the fact that we're making progress on this front."
Scientists today and through the weekend will be combing the area of the leak, looking for evidence of oil seeping through the ocean floor.
"It's premature to open the Champagne bottle, but this weekend we'll know whether we contained the monster or not," City University of New York physics professor and SyFy Channel host Michio Kaku told "Good Morning America" today.
There is no sign that the underwater pipe has burst, but scientists are keeping a close eye on the pipe's pressure, currently on the low side at about 7,000 psi, or pounds per square inch.
A sudden drop in pressure, Kaku explained, means the oil has found another way out.
"So far, we don't see that taking place," he said.
The 150,000-pound cap began to successfully contain the leak Thursday afternoon, holding back the oil that's shooting upward with the force of 70 fire hoses.
For the time being, work on the relief wells, a mere 100 feet from their target, has been suspended out of fear the drilling could disrupt the pressure to the crippled well.
News of the cap's success met with tepid applause at a Louisiana town hall.
"It's a relief that there's not oil coming into the gulf," shrimper Darla Rocks said, "but not a relief as far as me making a living, not a relief as far as my future."
Retired U.S. Coast Guard Adm. Thad Allen noted that the cap was not a solution, and that work on the leak would continue.
"This is merely an intermediate step to contain the oil, pending finishing the relief wells and plugging the hole," he said.
Kaku called the relief wells the "gold standard."
"You choke it from the bottom, cap it from the top," he said.
There were reportedly cheers and slaps on the back in the BP offices as workers realized they'd finally stopped the leak after more than 200 millions of gallons of oil spewed into the ocean. Live video of the leak showed no oil at the site where plumes of oil had been seen billowing into the Gulf since the disaster began April 20.
