While the dates of the exercises have not yet been released, it is known that around 2.6 million miles of land and sea area will be affected, including the entire eastern coastline, navy pier-side locations, harbors, airports and civilian ports, among others. The Gulf of Mexico will also be affected.
The Navy is considering which of three options to use for the exercises, including a “no-action alternative,” and will announce its decision by the fall of next year.
While an environmental impact study was conducted in preparation for the war games, environmentalists have expressed grave concerns about the fact that active sonar technology will be utilized to track mines and torpedoes as part of the exercises. The noise from sonar has disturbing effects on ocean mammals, and can distress or even kill animals like whales and dolphins. [Related: Discover other dangers threatening our planet at Environ.news.]
As reported by EcoRI, other risks to sea creatures “include entanglements, vessel strikes, ingesting of harmful materials, hearing loss, physiological stress, and changes in behavior.”
The Navy has announced that it will take precautions to prevent marine damage by having spotters on the lookout for mammals during the exercises, and by utilizing acoustic modeling recommended by the National Oceanic and Atmospheric Administration (NOAA).
The Guardian reported last year that a federal appeals court had ruled that the Navy was wrongly granted permission to use low-frequency sonar for testing and training purposes during peacetime. Permission had been granted for a five-year period back in 2012, and covered operations in the Atlantic, Pacific, Mediterranean and Indian Oceans. It allowed for the annual disturbance of 30 whales and 24 pinnipeds, as well as animals like sea lions and seals, which have front and rear flippers.

The court found that while it was evident that the Navy had closely followed the necessary guidelines and had made no deliberate attempt to harass or harm marine animals, adequate protection had not been afforded to biologically important parts of the world’s oceans.
They found that as a result, “a meaningful proportion of the world’s marine mammal habitat is under-protected.”
The court reversed an earlier lower court decision upholding the approval granted for these low-frequency sonar operations.
Of course, these proposed war games, while viewed as necessary by some, will likely do further large-scale damage to our ocean creatures.
For those opposed to the proposed military exercises, and who are concerned about potential harm to civilian or marine life, public comment is open until 29 August, and can be submitted online or in writing. A public hearing will also be held 19 July at the Hotel Providence, between 4:00 and 8:00 p.m.
