Gulf Oil Spill Still Killing Marine Life: Populations Down 60% 15 Years Later

New research reveals that marine life in the Gulf of Mexico has declined by approximately 60% following BP's 2010 Deepwater Horizon oil spill and has not recovered more than a decade later.

Marine life in the Gulf of Mexico fell by about 60% after BP's 2010 Deepwater Horizon oil spill and has still not fully recovered, according to new research published Monday in the Proceedings of the National Academy of Sciences (PNAS) [268607]. The April 2010 explosion of an offshore drilling unit 50 miles off the Louisiana coast triggered the largest marine oil spill in history, releasing 134 million gallons of oil into the ocean and killing 11 people while injuring 17 others [268607].

The study found "sudden, severe and persistent declines in the abundance" of fish, cephalopods—a class of marine animals that includes squid and octopuses—and other marine life, with these population drops lasting more than a decade [268607]. Scientists say the effects have lasted far longer than expected [267484].

Separate research examining hundreds of miles of the northern Gulf found that a vast deep-water ecosystem collapsed after the spill, with animal populations including octopus, krill, squid and shrimp declining sharply [266472]. The research concludes that the damage reached far beyond surface waters, affecting life in the deep sea, and whether these populations will recover—and how long it might take—remains unknown [266472].

The findings underscore the long-term environmental consequences of offshore oil drilling in the region, with scientists documenting persistent harm to marine ecosystems more than 15 years after the disaster [268607][267484].

Europe’s Seas Are Burning: Carbon Pollution Makes Ocean Heatwaves 100 Times More Likely

Europe’s oceans are in crisis mode this summer, with human-caused carbon pollution making extreme marine heatwaves up to 100 times more likely in some regions. New analysis shows that what used to be a once-in-a-century event is now a regular threat, with waters in the Celtic region around the British Isles reaching temperatures that would have been virtually impossible without climate change [222640]. The heat is pushing marine ecosystems to the brink, disrupting fisheries, and intensifying pressure on coastal communities already struggling with record air temperatures [222570].
