Study: Gulf deep-sea life still depleted a decade after Deepwater Horizon spill
New research published in the Proceedings of the National Academy of Sciences found that mesopelagic animal populations in the northern Gulf of Mexico—including octopus, krill, squid, shrimp and lanternfish—fell by 60 to 85 percent within three and a half years of the 2011 Deepwater Horizon spill, with little recovery since. After ruling out factors like temperature and oxygen levels, researchers concluded the BP oil and gas blowout was the most likely cause of what they called the fastest and most severe faunal decline ever documented for this type of ecosystem.
