Navy Loses Second Sonar Case

LOS ANGELES (KHNL) -- The U.S. Navy loses its second sonar case this week, this time over low-frequency sonar.

A federal court in San Francisco issued a preliminary injunction Wednesday, limiting the area in which the Navy may train with a low-frequency sonar system.

On Monday, another federal court enjoined the Navy's use of mid-frequency active sonar in exercised off southern California.

The preliminary injunction will place certain additional areas such as the Northwestern Hawaiian Islands Marine National Monument off limits to routine operations.

The order came in a lawsuit filed by a coalition of conservation organizations challenging the Navy's proposed deployment of the sonar system in over 75% of the world's ocean.
