NEW ORLEANS (AP) -- A prominent environmental group says continuing deaths of dolphins and sea turtles are a sign that the Gulf of Mexico is still feeling effects from the 2010 oil spill.
National Wildlife Federation scientist Doug Inkley said Tuesday the deaths -- especially in dolphins, which are at the top of the food chain -- are a strong sign of something wrong with the ecosystem.
The National Oceanic and Atmospheric Administration's fisheries service has said previously that many turtles probably drowned in shrimp nets and that a bacterial infection was the only common thread in the dolphin deaths.
Spokeswoman Connie Barclay says NOAA can't comment about Inkley's statement because its investigation is part of the federal tally of environmental damage for oil spill litigation.
NWF's report did not break any scientific ground.
