Coral Reefs and Shellfish Battle Acidifying Oceans

Coral Reefs and Shellfish Battle Acidifying Oceans

BY: SASKIA DE MELKER, PBS

Slip beneath the water's surface and you'll find a world teeming with life. Schools of yellowtail fish dart through colorful coral reefs. Spiny lobsters emerge from the crevices of ocean rocks searching for a tasty meal. And sea anemones nestle in the nooks of oyster beds.

Scientists are learning more about how carbon dioxide is dramatically changing the makeup of the oceans and the communities that depend on them.

In Our View: Oceans Threatened

Rising acid levels are addressed in panel's new recommendations, The Columbian

One of the first and most frequent rebuttals to environmental concerns is based on finances: Can we afford the solutions? Therefore, we'll begin this discussion of ocean acidification — admittedly a complex and still murky issue — by focusing on the financial aspects. 

Washington state leads the nation in production of farmed shellfish, providing 85 percent of sales on the west coast, including Alaska. The shellfish industry contributes $270 million annually to our state's economy and supports 3,200 jobs. It also contributes to tourism, as you know if you've ever dug razor clams on the coast. The impact of rising levels of acid in the ocean was dramatically illustrated between 2005 and 2009 with massive loss of oyster larvae in Northwest hatcheries, including the 2005 failure of larvae at Whiskey Creek Shellfish Hatchers on Netarts Bay near Tillamook, Ore. 

The good news is that Washington state also leads the nation in research and advocacy on this issue, evidenced by Tuesday's report from a panel of experts and stakeholders appointed 10 months ago by Gov. Chris Gregoire. The first of its kind at such a high level of state governance, the report includes 42 wide-ranging recommendations. Those include specifics such as increasing seaweed farming to remove carbon dioxide from ocean waters, and generalities such as reducing greenhouse gas emissions.

Ocean Acidification: It's Time to Act

Ocean Acidification: It's Time to Act

BY: GEORGE LEONARD, National Geographic

Consensus is hard. Any time you bring together a range of interests, it’s rare the group can speak in a unified voice and recommend a clear path forward. But that’s exactly what happened yesterday in Washington by its Governor and the state’s Blue Ribbon Panel (BRP) on Ocean Acidification. The panel made clear that options exist for tackling ocean acidification. Coastal states and businesses that are dependent upon a healthy ocean now have a road map for action, thanks to Washington’s leadership – and oyster growers in Oregon first sounding the alarm. Ocean acidification is happening now, and we can and should take action.

Rising ocean acidity off Washington state threatens shellfish, panel says

Rising ocean acidity off Washington state threatens shellfish, panel says

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.

The panel of scientists and policy experts convened by Gov. Chris Gregoire recommended dozens of actions to combat changes to ocean chemistry detected several years ago when oyster larvae in Pacific Northwest hatcheries began dying in large numbers.
