Navy Sonar: A Whale of a Problem for N.W. Marine Life

August 13, 2010

GREENBANK, Wash. – Underwater is usually a quiet place, but when the U.S. Navy is doing submarine security exercises, the calm can be shattered by blasts of high-intensity sonar. Marine experts say sonar affects dolphins and whales, along with other sea life – and can stun and even kill them. Whale-watchers along the Pacific Northwest coast monitor the sonar as well as whales’ behavior.

Howard Garrett, co-founder of the Orca Network, says major incidents are rare, but in the Northwest, there is concern about the Navy’s plans to expand the training areas.

“The proposed expansion of these exercise areas actually goes all the way down the coast to northern California, so it includes all of Oregon and Washington coastline, out in some places, 300 miles.”

October 2011. As another whale watching season draws to a close and the endangered southern resident Orca leave the protected inland waters of Washington State, it is worth looking back over a significant year in their poignant history. Officially listed as ‘endangered’ by the US National Oceanic and Atmospheric Administration (NOAA) in November 2005, this fragile population of only 87 killer whales continue to face numerous challenges to their survival, including salmon depletion, contamination by PCB’s (polychlorinated biphenyls), PBDE’s (polybrominated diphenyl ethers) and increasing vessel noise: here.
