BP has sounded the all clear, claiming Gulf of Mexico cleanup complete. Yet BP oil washes ashore nearly four years after the Deepwater Horizon disaster. This image from a Pensacola newspaper in late February 2014. (The Legal Examiner)

Oil that spewed out from the 2010 Deepwater Horizon site continues to pose an ecological risk. The Deepwater Horizon oil spill began on April 20, 2010 in the Gulf of Mexico on the BP-operated Macondo Prospect. The disaster is considered the largest accidental marine oil spill in the history of the petroleum industry.

New research suggests that around 16 percent of the approximately 5 million barrels of oil that burst into the Gulf of Mexico has settled into the seafloor. This is within a 40-kilometer radius of the damaged oil well. Thus the extent of the Deepwater Horizon oil spill may never be known, but it is far more damaging than previously thought.

...Oil on the ocean floor was detected through the analysis of around 3,000 ocean sediment samples. These samples were taken from 534 locations in the Gulf. This allowed the researchers to map out the remaining oil. These oil deposits were spread across a 3,200-square-kilometer region around the well.
