Marine life in the Gulf of Mexico’s twilight zone declined by approximately 60% following the 2010 Deepwater Horizon oil spill, according to a study published Monday in the Proceedings of the National Academy of Sciences.
Researchers found that the BP-operated well released 134 million gallons of oil into the region, where foundational marine species have shown little visible recovery over 13 years.
Marine scientist Boris Worm said the prolonged damage should inform discussions about deep-sea mining. National Science Foundation Director Rita Colwell urged greater emphasis on oil-degrading microbes rather than chemical dispersants when responding to future spills.
