Here ya go:
US government scientists yesterday raised questions about claims of vast plumes of oil hovering beneath the surface of the Gulf of Mexico as they issued a report saying that 75% of the worst spill in American history has been cleaned up or naturally dispersed.
The report by the National Oceanic and Atmospheric Administration suggests that the remaining oil is now so diluted that it is no longer a big threat.
The White House said it had a "high degree of confidence" in the findings. But critics were swift to point out that the estimates still leave about 1m barrels of oil in the Gulf – more than the entire size of the country's second worst oil spill – while the report shows that only about one-third of the oil was actually removed by the vast cleanup effort.
According to the NOAA report, burning, skimming and pumping from the wellhead to ships removed about 25% of the estimated 5m barrels of oil that poured into the sea for three months after an explosion on the Deepwater Horizon rig that killed 11 workers. A similar amount "naturally evaporated or dissolved".
The NOAA report said: "Just less than one quarter (24%) was dispersed (either naturally or as a result of operations) as microscopic droplets into Gulf waters.
"The residual amount – just over one quarter (26%) – is either on or just below the surface as light sheen and weathered tarballs, has washed ashore or been collected from the shore, or is buried in sand and sediments. Oil in the residual and dispersed categories is in the process of being degraded."
The report was compiled with the assistance of more than 25 of the US's best government and independent scientists.
