Sounds like a bad idea. The U.S. Navy wants to put a training range for lethal mid-frequency
sonar off the coast of Cape Hatteras, North Carolina smack in a key migratory route for menhaden, bluefish, striped bass, right whales, humpbacks, swordfish, eels, ...you name it, and if it travels the north/south route along the US Atlantic coast that is used by so much marine nature, it could be in deep trouble if the proposed sonar range gets set up in those waters.
The Navy's new Atlantic Undersea Warfare Training Range would create a 500-square-mile hub of sonar activity. While they could likely be forced to refrain from sonar testing during whale thru-migration times, many other species travel on their own schedules, and the survival of such species is every bit as important as that of the marine mammals.
We'll keep an eye on this...Stay tuned.
