U.S. Navy Plans to Expand its Submarine Testing Range to Include The Entire Pacific Northwest Coast

The public comment period for the proposed expansion of sonar testing is underway. Garrett says the Navy has been open to dialogue, although not much has changed since his group and others have challenged the use of sonar.

"They have a very limited repertoire of responses. It amounts to pretty much stationing sailors onboard with binoculars to look around to see if there are any whales that are obvious, and a few flyovers before they do these exercises."

The Navy says sonar is the best way to detect quiet, diesel-powered enemy submarines. Garrett hopes the discussion will expand, to include the reasons for its use in the first place.

"Their trump card is national defense. To look at an actual solution to that, you need to go beyond the issue of sonars and exercises – and look at international relations, and diplomacy."

The National Marine Fisheries Service allows some whale and dolphin deaths as part of sonar testing and training. The investigative website www.DCBureau.org reports that the Navy spends millions of dollars a year on marine mammal research, and most of its studies say sonar has minimal effects on whales. Studies funded by other sources disagree.
