Ten years after the Deepwater Horizon oil rig disaster, scientists are still studying the devastating impacts on the Gulf of Mexico. The resulting spill became one of the largest environmental catastrophes in American history. Where did the oil go? Have the deep corals recovered from the “dirty blizzard” that fell to the seafloor during the spill? Did widely applied dispersants help or hurt the oil-eating bacteria they are meant to assist? As researchers work to answer these questions and others, they also look ahead to what may happen next, as they use lessons learned to prepare for the next big spill.

A Decade After Deepwater is a Regional Emmy-winning episode from the South Florida PBS series CHANGING SEAS, which follows explorers and scientists as they shed light on how human activities are threatening ocean resources and uncover new information that could lead to scientific breakthroughs.
