Progress Reported in Efforts to Contain Massive BP Oil Spill VOA News 08 June 2010 U.S. Coast Guard Adm. Thad Allen (file photo) Photo: AP U.S. Coast Guard Adm. Thad Allen (file photo) The Obama administration says efforts to contain the massive oil spill in the Gulf of Mexico are making progress, with more oil captured each day. Speaking to reporters in Washington Tuesday, Coast Guard Admiral Thad Allen said almost 15,000 barrels of oil were contained in the past 24 hours, up from about 11,000 barrels the previous day.  Allen leads the government's response to the crisis. He says vessels on the surface collecting the oil have yet to reach their maximum capacity. Oil continues to escape from the leaking well, and Allen says experts led by the U.S. Geological Survey are working on finding an accurate flow-rate estimate to determine how much oil has been released into the Gulf. Allen says the oil company BP has closed one of four vents on the cap over the leaking well, but that oil is continuing to escape through the remaining three vents. At the same news briefing Tuesday, the head of the National Oceanic and Atmospheric Administration, Jane Lubchenco, said water samples taken by NOAA scientists have confirmed the presence of oil suspended below the surface of the Gulf. Subsurface oil was found in low concentrations in several areas hundreds of kilometers from the leak. Lubchenco said additional research is being done to determine the impact of the subsurface oil. Earlier, in an interview broadcast on U.S. television, President Barack Obama said he was speaking with fishermen in the region and experts to determine who needs to be punished for the spill - or, as he put it, "whose ass to kick." He took a strong stance against the head of oil giant BP, Tony Hayward, who has made controversial statements minimizing the impact of the spill. Hayward also has expressed frustration about the glare of p[ublic attention on the oil spill, saying at one point that he "wants his life back," but he has since apologized for those remarks. Mr. Obama said any government official who had made such statements would "not be working for me."  The president has said the economic impact of the spill will be "substantial." The spill has coated marshes and wildlife in black ooze and is threatening the livelihoods of the region's fishermen and other business owners. .
