On Monday, Congress was called on by a leading environmental organization to address the increasing threat to sea life that has been caused by decades of warming ocean temperatures and C02 pollution.

The action by Center for Biological Diversity included submitting a detailed letter to the House of Natural Resources Committee, the Senate Committee on Commerce, Science and Transportation, and the Senate Environmental and Public Works Committee.

Oceans' rising acidity a threat to shellfish — and humans

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.

In the United States and other coastal nations, ocean acidification has quickly become a common topic of scientific research. Ocean acidification also has become a public concern as news headlines warn of this potentially threatening byproduct of global climate change.

Ocean acidification emerges as new climate threat

HOMER, Alaska — Kris Holderied, who directs the National Oceanic and Atmospheric Administration’s Kasitsna Bay Laboratory, says the ocean’s increasing acidity is “the reason fishermen stop me in the grocery store.”

“They say, ‘You’re with the NOAA lab, what are you doing on ocean acidification?’ ” Holderied said. “This is a coastal town that depends on this ocean, and this bay.”

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.”
