Shellfish industry pins hope on Freeport research

Bangor Daily News

Following a recent Town Council appropriation, the town’s shellfish community has started what is being called a “historic” effort to address the rapid disappearance of soft-shell clams.

The effort is the first comprehensive, large-scale research project in Maine to study the most significant factors believed to be contributing to the decline of shellfish resources, said Brian Beal, a professor at the University of Maine at Machias and one of the scientists working on the project.

“To the best of my knowledge, I am not aware of any community that has raised this much money for a shellfish research project, ever,” he said. “(It) underscores the commitment by the town to this very important commercial resource that they co-manage with the state of Maine.”

Study shows oyster reefs buffer acidification of Chesapeake Bay

Study shows oyster reefs buffer acidification of Chesapeake Bay

Virginia Institute of Marine Science

A new study co-authored by Prof. Roger Mann of 's Virginia Institute of Marine Science adds a new item to the list of oyster reef benefits — the ability to buffer increasing acidity of ocean waters.

Concerns about increasing acidity in Chesapeake Bay and the global ocean stem from human inputs of carbon dioxide to seawater, either through burning of fossil fuels or runoff of excess nutrients from land. The latter over-fertilizes marine plants and ultimately leads to increased respiration by plankton-filtering oysters and bacteria. In either case, adding carbon dioxide to water produces carbonic acid, a process that has increased ocean acidity by more than 30 percent since the start of the Industrial Revolution.

Can Acid Neutralizers Help Coral Reefs Bounce Back?

NPR

Coral reefs are in trouble worldwide, from a host of threats, including warming ocean temperatures, nutrient runoff and increasing ocean acidity. A noted climate scientist from California has been conducting an experiment on Australia's Great Barrier Reef to see whether antacid could boost coral growth.

Kathleen Nisbet, and her father Dave farm oysters in Waxhington's Willipa Bay. They recently shifted some of their business to Hawai'i after ocean acidification started killing baby oysters in hatcheries.

WA’s First Ocean Acidification Legislation

WA’s First Ocean Acidification Legislation

Slightline Daily

On the heels of Washington State’s pioneering efforts to identify local steps to slow ocean acidification, Sen. Kevin Ranker (D-Orcas Island) has introduced legislation to begin coordinating that response. SB 5547 would create a new council of elected and tribal representatives and affected industries to oversee research and action to curb profoundly troubling changes in ocean chemistry.

The bill would also include acidification as a possible justification for extending urban sewer services to rural areas (normally not allowed under the state’s Growth Management Act), in areas where local pollution from leaky septic systems combines with global carbon dioxide emissions to make the problem worse.
