HONOLULU, Hawaii (AP) -- The Navy said it will rely on a different type of sonar during exercises off of Hawaii after environmentalists won a temporary restraining order stopping the service from using a high-intensity sonar that could harm marine mammals.
U.S. District Judge Florence-Marie Cooper's order came after the Defense Department granted the Navy a six-month exemption from the federal Marine Mammal Protection Act to allow use of the "mid-frequency active sonar."
Environmentalists had argued the exemption was aimed at circumventing the lawsuit they filed last week to stop the Navy's use of the sonar in the Rim of the Pacific 2006 exercise.
Government lawyers were reviewing the ruling, and the Navy will probably respond soon, said Jon Yoshishige, a spokesman for the U.S. Pacific Fleet in Hawaii.
Meanwhile, participants in the multinational exercise will search for submarines using "passive sonar," which historically has been used during such exercises, Vice Adm. Barry Costello, commander of the U.S. 3rd Fleet, said in a statement late Monday.
Active sonar locates objects by analyzing sound bounced off them, while passive sonar involves analyzing noises generated by the objects.
