Northwest Faces Greater Risks From Acidifying Waters

Feb 24, 2015

The Pacific Northwest faces a higher risk of economic harm from ocean acidification than other parts of the country, according to a new study released Monday.

The study, published in the journal Nature Climate Change, found a "potent combination" of risk factors along the coasts of Oregon and Washington. The region has cold ocean water that absorbs carbon dioxide more readily than warmer water, and it has upwelling ocean currents that bring corrosive water to the surface.

After China banned all imports of West Coast shellfish, officials in the U.S. defended the imports by saying the Chinese tested the wrong parts of the clams.

Officials in Washington have learned that inorganic arsenic was the toxin detected in a shipment of geoduck from their state to China, not the toxin causing paralytic shellfish poisoning, or PSP, as they previously believed.

SEATTLE -- New details have been released about geoduck shipments that Chinese officials say contained high levels of inorganic arsenic and the toxin that causes paralytic shellfish poisoning, or PSP.

In response to their testing, the Chinese government instituted Dec. 3 a ban all U.S. harvested geoduck clams and other bivalve shellfish from Alaska, Washington, Oregon and Northern California.

On Monday scientists from the National Oceanic and Atmospheric Administration will begin a one-month US West Coast expedition to investigate ocean acidification, an issue that poses a serious threat to the Pacific Northwest’s shellfish industry.

“We will for the first time not only study the chemistry of acidification, but also study the biological impacts on the marine ecosystems in the open ocean,” says Richard A. Feely, a scientist from NOAA’s Pacific Marine Environmental Research Laboratory in Seattle. Feely is co-chief of the mission.

Washington’s Department of Health closed some shellfish beds in South Puget Sound Wednesday for the first time because of elevated levels of diarrhetic shellfish toxin.
