Back in 2010, Greenpeace filed a Freedom of Information request covering endangered species affected by the Deepwater Horizon spill. They just received a response from NOAA, and it included more than 100 photos. They’re disturbing: The ones Greenpeace has released so far show endangered Kemp Ridley’s sea turtles, dead and covered in oil.

The photos below the jump are even worse.

Grist thanks its sponsors. Become one.

Mother Jones has more, too. Kate Sheppard reports:

Most photos are missing dates and descriptions, though the FOIA request covered the period of April 20 to July 30, 2010. But they’re pretty shocking — which is probably why they weren’t made public at the height of the spill. “It just makes me furious,” said John Hocevar, a marine biologist who works for Greenpeace. “I had so many conversations with people in various government agencies working on the Gulf spill, and I feel like they were hiding things from all of us.”
