Dolphins hit by Deepwater Horizon spill at risk from new drilling and river plan

Up to 45% of Barataria Bay's dolphins died after 2010. Now they face the threat of new drilling and a Mississippi River scheme

Nearly 80% of dolphins exposed to oil in the Deepwater Horizon disaster remain badly affected nearly 12 years later, according to new research, even as the Biden administration continues to approve leases for oil and gas drilling in the Gulf of Mexico.

Scientists looked at the long-term impact of the oil spill on bottlenose dolphins living in Barataria Bay, near New Orleans.
