I read it thoroughly, Douglas.  That is why I am asking you if U. S. Navy sonar use is a problem for echo-locating marine mammals in the Haro Strait, inasmuch as that is the maritime area under discussion.  As far as I know it is not, but I am willing to be corrected.  There are areas in the PNW where the Navy does extensive sonar testing, research and training, such as particularly deep portions of Hood Canal, but there are few, if any, whales there to be adversely affected.  As the linked article observed, the Navy does not need to conduct its training and research everywhere.  If we know of problem areas we should bring them to the Navy's attention, which is how the agreement covering southern California and Hawaii came about.
