How a 2010 oil spill still shapes cleanup strategies today
Fourteen years after the Deepwater Horizon disaster, scientists remain skeptical that today’s oil spill response methods would be significantly more effective at managing a similarly catastrophic event.
In short:
- The Deepwater Horizon spill released 4.9 million barrels of oil into the Gulf, and only 2-6% was recovered.
- Advances in oil spill science and technology have improved recovery methods, but they remain largely ineffective for large spills.
- The rise of new oil production methods, including deep-sea drilling, increases the likelihood of future spills.
Key quote:
"I knew immediately that this would be ecologically and economically disastrous."
— Jeffrey Short, now-retired scientist from the US National Oceanic and Atmospheric Administration
Why this matters:
As long as we use fossil fuels, spills are likely to happen. Oil spills are the third largest source of oil in the sea. Experts warn that, despite some advances in spill response, another Deepwater Horizon-level spill would be similarly catastrophic.

The lasting impact of the Deepwater Horizon spill on marine life
A recent expedition to the Gulf of Mexico has revealed ongoing environmental damage from the Deepwater Horizon disaster, showing little signs of recovery for the marine ecosystem.
In short:
- Fourteen years after the Deepwater Horizon explosion, marine life at the site continues to exhibit signs of distress, including discolored and injured crabs.
- The seabed remains largely devoid of its usual inhabitants like sea cucumbers and corals, indicating a slow recovery process.
- While some new life forms are beginning to appear on the wreckage, the overall biodiversity remains significantly reduced compared to pre-disaster levels.
Key quote:
"We may not actually ever see recovery,"
— Craig McClain, deep-sea biologist at the University of Louisiana at Lafayette.
Why this matters:
The persistent environmental damage highlighted by this expedition underscores the long-term impacts of oil spills on marine ecosystems. Read more: Unplugged: Abandoned oil and gas wells leave the ocean floor spewing methane.

Jacqueline Savitz: No, President Trump is not the 'environmental president'
If Trump wants to be known as the "environmental president" he should start acting like it. Expanding his decision to block offshore drilling in the rest of the Atlantic, the Pacific and Arctic would be a real environmental legacy.
