Skytruth coal and other minerals throughout the United States. In April 2010, the offshore oil drilling rig Deepwater Horizon, operated by BP P.L.C., exploded in the Gulf of Mexico and triggered the largest accidental oil spill in history. In cooperation with Florida State University, SkyTruth estimated the amount of oil flow from the damaged well-using satellite imagery and determined based conservative estimates using the visible surface slick that the flow of oil was between 5 and 25 times greater than BP reported. SkyTruth was the first organization to challenge BP's claims, and continued to monitor and document flow from the well
Deepwater Horizon oil spill more than wide and deep. In a major study on the plume, experts were most concerned about the slow pace at which the oil was breaking down in the cold, water at depths of . In late 2012, a study from Georgia Tech and Universidad Autonoma de Aguascalientes in Environmental Pollution journal reported that Corexit used during the BP oil spill had increased the toxicity of the oil by 52 times. The scientists concluded that "Mixing oil with dispersant increased toxicity to ecosystems" and made the gulf oil spill worse." The three basic approaches for removing the oil from the
