Low-frequency sonar used for training and testing can injure whales and other marine life, and disrupt their feeding and mating
A federal appeals court ruled on Friday that the US Navy was wrongly allowed to use sonar in the nation’s oceans that could harm whales and other marine life.
The ninth circuit court of appeals reversed a lower court decision upholding approval granted in 2012 for the Navy to use low-frequency sonar for training, testing and routine operations.
