APTOPIX Gulf Oil Spill

Millions of gallons of oil from the Deepwater Horizon oil spill didn’t get cleaned up, and instead settled in the sediment of the Gulf of Mexico’s floor, a new study has found.

The study, published in the journal Environmental Science and Technology, found that 6 to 10 million gallons of oil from the spill are buried in the seafloor. The researchers measured the amount of carbon 14 — a radioactive carbon isotope that’s found in organic material but not found in oil — in an approximately 24,000 km² area of sediment near the spill site, a process which allowed them to see what parts of the sediment were low in carbon 14 and thus contained oil.
