SEATTLE (AP) — The U.S. Navy must shut down sonar use if marine mammals are spotted near training exercises and take other precautions when using the sound-wave technology or explosives off the Northwest coast, NOAA’s Fisheries Service said Tuesday.

The Navy requested authorization for the training exercises from NOAA under the Marine Mammal Protection Act because noise from mid-frequency sonar and explosives may affect the behavior of some animals or cause temporary hearing loss.

Environmentalists said NOAA’s safety measures are ineffective because animals can be harmed outside of the monitoring zone and some marine mammals most vulnerable to sonar are extremely difficult to spot.
