Navy Granted Permission to Use Sonar

HONOLULU (KHNL) - The U.S. Navy has been granted permission to use a sonar system environmentalists claim is harmful to whales and dolphins.

The go-ahead comes from a federal regulatory agency, and coincides with the upcoming Rim-Pac naval exercises happening in Hawaiian waters.

The sonar will be used in exercises after the 4th of July.

The Natural Resources Defense Council says it will file a motion in court Wednesday to block the action.

Council officials say military sonar has been linked to dozens of mass strandings of whales around the world. The navy says its sonar technology is not harmful to marine life.
