Washington State Targets Pollutants that Lead to Ocean Acidification

Washington State Targets Pollutants that Lead to Ocean Acidification

BY: DAVID MALAKOFF, Science

In the first state-level action of its kind, the governor of Washington today announced that her state will try to protect valuable shellfish industries and marine life from ocean acidification. Responding to a report that she requested, Governor Chris Gregoire said she has directed state agencies to take steps to reduce the pollutants that contribute to acidification. She also plans to ask the state legislature to establish a new acidification research center at the University of Washington (UW), Seattle.

Gregoire orders action on ocean acidification

SEATTLE -- Rising acidity levels in the oceans pose a serious threat to shellfish and other marine life, and tackling that problem in Washington state will require reducing carbon dioxide emissions, keeping polluted runoff out of marine waters, and increasing monitoring at hatcheries, a group of experts recommended Tuesday.

Washington Gov. Chris Gregoire (D) ordered state agencies on Tuesday to take steps to address the ocean’s increasing acidity, making it the first state to adopt a policy to take on what scientists describe as a growing environmental concern.

Ocean acidification poses a threat to the state’s $270 million shellfish industry, as well as to critical habitat off its shores.

Peering into the microscope, Alan Barton thought the baby oysters looked normal, except for one thing: They were dead.

Slide after slide, the results were the same. The entire batch of 100 million larvae at the Whiskey Creek Shellfish Hatchery had perished.

An acidic ocean threatens shellfish farms

An acidic ocean threatens shellfish farms

For more than two decades, Rob Saunders grew his shellfish larvae in ordinary seawater drawn from the pristine natural environment of Baynes Sound, one of the most productive shellfish farming areas on B.C.’s West Coast. Now the water in Baynes Sound is so acidic, Mr. Saunders’ fragile seed stock will die unless he artificially adjusts the PH level in his hatchery tanks. “Because of ocean acidification the only way we can grow any larvae – oysters, clams, mussels, geoducks, you name it – is to take the CO2 out of the seawater,” said Mr. Saunders, CEO of Island Scallops, the largest producer of shellfish seed stock on province’s West Coast. “We would have been out of business this year if we didn’t figure out how to solve the problem.”
