An infographic summarizes some of the findings.
The NWF also highlighted these findings:
* Dolphin deaths in the area affected by oil have remained above average every month since just before the spill began. (The infant dolphin data was gathered in January and February of 2013.)
* NOAA called the dolphin die-off "unprecedented" - a year ago. While NOAA is keeping many elements of its dolphin research confidential pending the conclusion of the ongoing trial, the agency has ruled out the most common causes of previous dolphin die-offs.
* More than 1,700 sea turtles were found stranded between May 2010 and November 2012 - the last date for which information is available. For comparison, on average about 240 sea turtles are stranded annually.
* A coral colony seven miles from the wellhead was badly damaged by oil. A recent laboratory study found that the mixture of oil and dispersant affected the ability of some coral species to build new parts of a reef.
* Scientists found that the oil disaster affected the cellular function of the killifish, a common baitfish at the base of the food web. A recent laboratory study found that oil exposure can also harm the development of larger fish such as mahi mahi.
