GoKawiilStudy: Gulf of Mexico deep-sea species still down 60% since 2010 BP spill
A study in the Proceedings of the National Academy of Sciences found that populations of octopus, squid, krill, shrimp, and lanternfish in the Gulf of Mexico fell by at least 60 percent in the years after the Deepwater Horizon disaster and have shown little sign of recovery 16 years later. Researchers based the findings on acoustic surveys and thousands of net samples across a wide area of the deep sea, and also documented reduced genetic diversity in affected populations.
GoKawiil's interpretation of the reporting above, not reported fact.
The researchers stop short of directly blaming the 2010 spill, calling it only 'the most parsimonious explanation,' which suggests the causal link, while strongly implied, remains scientifically cautious. Reduced genetic diversity could leave these populations less able to adapt to future environmental stress, according to the study's authors, potentially compounding the long-term ecological damage beyond the initial die-off.
- Deep-sea species in the Gulf of Mexico have declined by at least 60% since the 2010 Deepwater Horizon spill.
- Oil-related compounds have been found in squid, octopus flesh, and fish eggs, potentially impairing reproduction.
- Researchers also found reduced genetic diversity, raising concerns about species' resilience to future change.
