The 2010 Deepwater Horizon spill caused widespread damage in the Gulf of Mexico, but some parts of this complex ecosystem fared better than others.
The Deepwater Horizon oil disaster catalyzed a decade of research on oil contamination in the Gulf of Mexico, from surface waters to the seabed, with surprising findings.
The BP Deepwater Horizon blowout on April 20, 2010 triggered the largest offshore oil spill in history. Ten years later, post-spill reforms are being undone and the Gulf of Mexico remains vulnerable.
