The Navy and several plaintiffs, including the Natural Resources Defense Council (NRDC), the International Fund for Animal Welfare, the Cetacean Society International, the League for Coastal Protection, the Ocean Futures Society, and Jean-Michel Cousteau, entered into a settlement agreement to resolve a worldwide challenge to the Navy's testing and training with mid-frequency active sonar. The settlement essentially adopts the long range program for environmental analysis and research that the Navy undertook in August 2005, months before this lawsuit was originally filed. The Navy will continue to implement a variety of protective measures previously developed in cooperation with the National Oceanic and Atmospheric Administration.
