GoKawiilStudy: 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.
GoKawiil's interpretation of the reporting above, not reported fact.
The researchers suggest the die-off may be creating genetic bottlenecks that could further impede recovery, and could also diminish the ocean's capacity to carry carbon dioxide into the deep sea. They argue the findings imply deep-sea habitats are far less resilient to industrial disturbance than assumed, which could bear on debates over proposed deep-sea mining before baseline ecological conditions are even established.
- Deepwater animal populations fell 60-85% after the 2011 spill with scant recovery over a decade
- Researchers call it the most severe deep-sea faunal decline ever documented
- Findings raise concerns about deep-sea mining's risks to poorly understood ecosystems
