The Navy have been blasting the sea with louder than rock concert sounds, hunting for Red October. Apparently the U.S. Navy hasn't done enough to ensure its sonar technology isn't hurting whales tho. Regardless this decision being overturned, the Navy had already planned to phase out much of the harmful sound.
"The Court of Appeals understood that the Navy can do more to reduce the risk of its powerful long-range sonar, especially in the vast reaches of the ocean where too little is known," Michael Jasny of the National Resource Defense Council, one of several organizations behind suit, said in a statement. "Ignorance is no excuse for inaction where commonsense safeguards recommended by the government's own scientists can prevent avoidable harm."
The court's ruling will send both parties back to a district court for further consideration. But time may well run out on the NMFS's decision anyway; it expires in 2017. The Navy has already agreed to limit its use of sonar in certain locations starting in 2018. Soon, the only waves in the ocean will be the natural ones made of water, not man-made ones that come from sound.
