Environmental impact of the Deepwater Horizon oil spill Environmental impact of the Deepwater Horizon oil spill The 2010 "Deepwater Horizon" oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about of crude oil making it the largest marine oil spill. Both the spill and the cleanup efforts had effects on the environment. The oil spill was called the "worst environmental disaster the US has faced" by White House energy adviser Carol Browner. The spill was by far the largest in US history, almost 20 times greater than the usual estimate of the Exxon Valdez oil spill. Factors
Environmental impact of the Deepwater Horizon oil spill that the damage from the spill would rapidly resolve, three years into the recovery dolphins continue to die, fish are showing strange lesions, corals in the gulf have died and oil still remains in some marsh areas. Due to both its size and the way it was handled, there is little previous research to predict long-term effects. At the 2013 "Gulf of Mexico Oil Spill and Ecosystem Science Conference", oceanographer David Hollander presented data that showed as much as one-third of the oil released during the spill may still be in the gulf. Researchers described a phenomenon called "dirty blizzard":
