New England Takes on Ocean Pollution State By State

By Patrick Whittle, Associated Press, March 30, 2015

Portland, Maine — A group of state legislators in New England want to form a multi-state pact to counter increasing ocean acidity along the East Coast, a problem they believe will endanger multi-million dollar fishing industries if left unchecked.

The legislators’ effort faces numerous hurdles: They are in the early stages of fostering cooperation between many layers of government, hope to push for potentially expensive research and mitigation projects, and want to use state laws to tackle a problem scientists say is the product of global environmental trends.

But the legislators believe they can gain a bigger voice at the federal and international levels by banding together, said Mick Devin, a Maine representative who has advocated for ocean research in his home state. The states can also push for research to determine the impact that local factors such as nutrient loading and fertilizer runoff have on ocean acidification and advocate for new controls, he said.

“We don’t have a magic bullet to reverse the effects of ocean acidification and stop the world from pumping out so much carbon dioxide,” Devin said. “But there are things we can do locally.”

The National Oceanic & Atmospheric Administration says the growing acidity of worldwide oceans is tied to increased atmospheric carbon dioxide, and they attribute the growth to fossil fuel burning and land use changes. The atmospheric concentration of carbon dioxide increased from 280 parts per million to over 394 parts per million over the past 250 years, according to NOAA.

Carbon dioxide is absorbed by the ocean, and when it mixes with seawater it reduces the availability of carbonate ions, scientists at Woods Hole Oceanographic Institution said. Those ions are critical for marine life such as shellfish, coral and plankton to grow their shells.

The changing ocean chemistry can have “potentially devastating ramifications for all ocean life,” including key commercial species, according to NOAA.

The New England states are following a model set by Maine, which commissioned a panel to spend months studying scientific research about ocean acidification and its potential impacts on coastal industries. Legislators in Rhode Island and Massachusetts are working on bills to create similar panels. A similar bill was shot down in committee in the New Hampshire legislature but will likely be back in 2016, said Rep. David Borden, who sponsored the bill.

Ocean acidification bill supporters make case to Maine Legislature.

By Ronald Huber | Jan 13, 2014 The Republican Journal

It was standing room only at the Maine Legislature’s Marine Resources Committee as supporters of  LD 1602  the “Save Our Shellfish” bill, made their case for appointing of a coastwide multisector  committee to study how to reduce the impact of oceanic acidification on Maine species and what proactively to do, fishery by fishery.

Not only were clammers, shellfish farmers and the scientific community evident, The groundfish industry called for the scope to be broadened to consider all Maine marine species from plankton up. A wastewater management too was represented, and a wide spectrum of Maine ENGOs weighed in as well.

The bill’s full title is Resolve, Establishing the Commission To Study the Effects of Ocean Acidification and Its Potential Effects on Commercial Shellfish Harvested and Grown along the Maine Coast

In addition to  bill sponsor Mick Devin, and DMR Commissioner Pat Keliher,  fifteen members of the public and interest groups testified.

Senator Chris Johnson, committee co-chair, gave the introduction to the public hearing (mp3)

Representative Mick Devin Sponsor laid out the case for LD 1602 spending time money and energy getting up to speed on the impact acidification is having on maine marine and estuarine species.

DMR Commissioner Pat Keliher followed, calling for achievable outcomes, not only another report – bottom line is produce something that will help Maine. (3minutes)

Suzy Arnold of Island Institute spoke next. She noted that the pH of some  Gulf of Maine waters is 30% lower than it was (4min 9sec). If our blood went that that much lower we’d be in a coma, Arnold said. The increased acidity is dissolving shells of baby shellfish. Critical prey like zooplankton are affected too. Crabs seem  okay but have thicker shells and slower growth.  The California rockfish and other fish  exhibit confusion & anxiety when acidified on the west coast.

Arnold said that compared to bivalves, nothing known about lobster acidification. This must be a priority. She said Seagrant & Cooperative extension agreed. She noted that there will be a daylong meeting Thursday in Augusta to ID priorities, and that all are welcome.
