"Federal regulators this month gave the US Navy permission, good for one year, to train with sonar in Hawaii waters.
The Navy warned its exercises may, though weren't expected to, harm or kill whales and other marine mammals". LINKThey've got plenty of ocean to train in - Why use a whales breeding ground ?

They must e training operators to distinguish whales from submarines or possibly a new sonar that is intended to kill submarines or make it very unpleasant for the submariners? Why use an aera where whales are known to be unless you want them there specifically?

The effects of sonar on mammals has been known since WW2 when it was discovered that it could shred the surface of air pockets in the body (lungs, sinus, etc). It has since been used as a defence against enemy divers approaching vessels.
I used to work as a commercial diver in the oilfields and all sonar activity was banned in areas of diving operations for this very reason. It just seems odd that they are targetting areas where mammals are known to congregate. New weapon ?
