Shell stuff: monitoring the health of California’s oysters amid climate change

Endangered black abalone receive an aromatic spa treatment while hundreds of baby oysters float in tiny cages next to winding strands of seagrass, their growth tracked and measured by resident ecologists.

In the world of shelled invertebrates, researchers handle their subjects carefully, especially the babies who are hypersensitive to change and tend to die quickly and without warning, a habit that make them more difficult to study than their more resilient parents.

As these shelled creatures grow, researchers measure their shells, record water chemistry, and take pictures, searching for clues and patterns that will help resolve mysteries about the health of shells and changing ocean environments.

Episode 3: how can humans help oysters adapt to stresses from ocean acidification? (audio)

The Pacific Northwest supports a 270 million dollar per year shellfish industry. Human-induced climate change has increased global levels of atmospheric carbon dioxide. More carbon dioxide then enters ocean water, making it more corrosive. As a consequence, oysters and other shellfish that rely on alkaline seawater conditions to precipitate calcium carbonate and build their shells find it harder to grow. The Whiskey Creek Shellfish Hatchery in Tillamook, which supplies Netarts Bay with oysters and also sells larvae to farmers across the Northwest, experienced larval die-offs of nearly 75% in 2007.

Washington County files latest lawsuit targeting big oil over climate damages

King County says its shellfish industry is endangered by ocean acidification

On May 9, yet another local government joined the roster of cities and counties suing fossil fuel companies for climate-change-related damages when King County, Washington—home to Seattle—filed suit against the five largest publicly traded oil corporations.

Coral species can regulate calcium content to cope with rising ocean acidity: Aussie research

SYDNEY, May 2 (Xinhua) — Some coral species are able to regulate calcium buildup in their skeletons to better survive acidic oceans caused by rising CO2 levels, according to a latest Australian research.

The findings improved understanding of how the crucial marine organisms cope with environmental challenges.

Sens. King, Collins push for more research on ocean warming in Gulf of Maine

A letter to the head of the National Oceanic and Atmospheric Administration comes after a Portland Press Herald report on record-warm water flowing into the Gulf’s main entrance.

 U.S. Sens. Susan Collins and Angus King have urged the federal government to improve efforts to understand the causes and effects of the rapid warming of the Gulf of Maine, which threatens to disrupt Maine’s traditional fisheries and the ecosystem that supports them.

“We need greater resources, enhanced monitoring of subsurface conditions, and a better understanding of the diversity of factors that are simultaneously impacting the Gulf of Maine, from changes in circulation and water temperature to ocean acidification,” the senators wrote in a letter Monday to the head of the National Oceanic and Atmospheric Administration, Tim Gallaudet.

Shellfish farmers collaborate to fight climate change (audio)

SEATTLE – For shellfish farmers, climate change isn’t a future risk, but a present-day challenge to their industry – and farmers on the West and East coasts are joining forces to fight it.

The new Shellfish Growers Climate Coalition is raising awareness about the effects of carbon pollution on the industry. On the West Coast, the biggest issue is ocean acidification from dissolved carbon dioxide, which makes it difficult for shellfish larvae to grow their shells.

Bill Dewey, the public affairs director for Taylor Shellfish Farms, says acidification decimated their larvae a decade ago. In the aftermath, the company was able to set up a small-scale treatment solution.

Seaweed farming and its surprising benefits (text and video)

Seaweed may be thought of as a nuisance, but an increasing number of fishermen, scientists and consumers are seeing it as a solution

Many of us think of seaweed as a nuisance — the slimy, sometimes smelly stuff that clogs fishermen’s nets, gets tangled in our ankles in the ocean, and washes up unwanted on the beach. Even its name — sea-weed — implies something undesirable.
