US govt silencing dissenting scientists on oil spill issue

A prominent oceanographer, who was among the first to say official estimates understated the volume of the Gulf of Mexico oil spill, charged Tuesday that a federal agency is punishing scientists whose findings disagree with government figures.

Ian MacDonald, an oceanographer with Florida State University, who more than two weeks ago said the oil spill was likely five times as large as the 5,000 barrel-a-day estimate from the National Oceanic Atmospheric and Administration, said the agency is attacking scientists who challenged government estimates, while itself doing little to glean new information about the spill size.

“The scientific community in the Gulf of Mexico is fairly small ... and we've been very dedicated for a long time and not only is nobody listening to us in this, but it seems like they really want us to shut up,” MacDonald said. “It's very, very punitive and anybody who is doing this is getting attacked by NOAA.”

A NOAA spokesman did not address MacDonald's claims directly, but said that the agency's spill response includes scientists with key federal agencies as well as partners in the scientific community and the private sector.

80,000 barrels a day?

The stinging criticism comes amid debate about the size of the oil spill emanating from BP's Macondo well about 40 miles off the coast of Louisiana. An April 20 blowout in a well under 5,000 feet of water triggered the oil spill, destroyed the Deepwater Horizon drilling rig, and killed 11 workers.

Some independent scientists have made estimates that sharply depart from NOAA's estimate, which equates to 210,000 gallons a day.

Based on various models, including measurements of satellite imagery of the surface slick and an analysis of wellhead video released by BP, some scientists estimate the volume of oil spilling from the well as 25,000 to 80,000 barrels a day.
