A new report released this week by the National Academy of Sciences estimates that the Deepwater Horizon Gulf of Mexico Oil disaster from April of 2010 left at least 10 million gallons of congealed oil on the floor of the Gulf.
BP disputes the findings saying that “the authors fail to identify the source of the oil.”
A new study shows that cleanup barely scratched the surface

We all saw the images of oil-coated birds and shorelines in the wake of the 2010 Deepwater Horizon spill. These were the most visible impacts of the catastrophe, but much of the oil that gushed from the busted Macondo wellhead 5,000 feet underwater never made it to the surface. Of the estimated 5 million barrels that spilled, approximately 2 million stayed trapped in the deep ocean. And up to 31 percent of that oil is now lying on the ocean floor, according to a new study.
Based on an analysis of sea-floor sediment samples collected from the the Gulf of Mexico, geochemists at the University of California-Santa Barbara were able to offer the first clues about the final resting place of hundreds of thousands of barrels of oil. Their results were published today in the Proceedings of the National Academy of Sciences.
The data, which was gathered as part of the ongoing federal damage assessment, shows “a smokingly clear signal, like a bulls-eye” around the Macondo well, said lead author David Valentine.
In a related story published last week in GRIST, researchers claim that they can now identify the fingerprints from tracking operations in polluted water contaminated by fracking. Maybe the day is not so far off where forensics will link BP to the world’s greatest ecological catastrophe in ways that are undeniable, even in their own minds.
