Federal agencies have approved more than $200 million for 18 projects to restore the open Gulf of Mexico after the 2010 BP oil spill.
The projects are described in a report released Tuesday.
The biggest is about $52 million to study deep-sea habitats.
The smallest is about $300,000 to find ways to keep sea turtles from swallowing longline fishing hooks or tangled in the lines.
The money is from a fund created by BP in a 2016 settlement for natural resources damage.
A nonprofit group called the Ocean Conservancy calls it a major conservation milestone for the Gulf.
