Scientists are raising concerns about a new federal report that says most of the oil from the Gulf of Mexico spill has been dispersed or contained.


The report (pdf) released yesterday attempts to clear up a mystery surrounding the fate of the millions of gallons of oil that gushed from the failed BP PLC well before it was capped in mid-July. The report says all but 26 percent of the spilled oil is accounted for.


Much of the oil that remains is being degraded or cleaned up on Gulf Coast beaches, the report states.


"The bottom line here is we can account for all but about 26 percent of the oil, and of that, much of that is in the process of being degraded and cleaned up on the shore," Jane Lubchenco, administrator of the National Oceanic and Atmospheric Administration, said yesterday at the White House.


But some scientists say such a statement is misleading.


"For months, there has been a great huge shadow over the Gulf; that shadow has lifted, and that is good, and we're all glad and relieved," said Ian MacDonald, a professor of biological oceanography at Florida State University who has been tracking the flow of the spill. "But we shouldn't lift our guard, and we shouldn't pretend it is over."


The report is based on a calculation made earlier this week by a team of federal scientists that about 206 million gallons of oil had leaked from the well. The scientific team can calculate the precise amount of oil that has been contained, but in other recovery efforts like burning and skimming, calculations are less precise.


The report acknowledges it is based on the "best available scientific estimates," but scientists are concerned that the report was presented with more certainty than it likely deserves.

BP Deepwater Horizon Oil Budget:
What Happened To the Oil?



The National Incident Command (NIC) assembled a number of interagency expert scientific teams to estimate the quantity of BP Deepwater Horizon oil that has been released from the well and the fate of that oil. The expertise of government scientists serving on these teams is complemented by nongovernmental and governmental specialists reviewing the calculations and conclusions. One team calculated the flow rate and total oil released. Led by Energy Secretary Steven Chu and United States Geological Survey (USGS) Director Marcia McNutt, this team announced on August 2, 2010, that it estimates that a total of 4.9 million barrels of oil has been released from the BP Deepwater Horizon well. A second interagency team, led by the Department of the Interior (DOI) and the National Oceanic and Atmospheric Administration (NOAA) developed a tool called the Oil Budget Calculator to determine what happened to the oil. The calculator uses the 4.9 million barrel estimate as its input and uses both direct measurements and the best scientific estimates available to date, to determine what has happened to the oil. The interagency scientific report below builds upon the calculator and summarizes the disposition of the oil to date.


In summary, it is estimated that burning, skimming and direct recovery from the wellhead removed one quarter (25%) of the oil released from the wellhead. One quarter (25%) of the total oil naturally evaporated or dissolved, and 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 tar balls, 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 below describes each of these categories and calculations. These estimates will continue to be refined as additional information becomes available.
