The NRDC is going to sue the U.S. Navy over a new kind of sonar. From Reuters via CNN:
Reynolds cited Navy estimates that the LFA system generates sounds capable of reaching 140 decibels more than 300 miles (483 kms) away….
But the fisheries service, a division of the U.S. Commerce Department, said it approved the Navy’s use of the sonar after determining that marine mammals were “unlikely to be injured.”
