Posted on EPOCA blog: 25 May 2011 Increasing levels of ocean acidity could spell doom for British Columbia’s already beleaguered northern abalone, according to the first study to provide direct experimental evidence that changing sea water chemistry is negatively affecting an endangered species. The northern abalone–prized as a gourmet delicacy–has

Oregon Sea Grant videos on ocean acidification
Dr. Richard Feely of NOAA’s Pacific Marine Experimental Lab discusses new findings about how increased carbon dioxide in the atmosphere is making the oceans more acidic, and what that bodes for ocean ecosystems and the marine animals that inhabit them. (1) What is ocean acidification (1:38) (2) How are ocean animals affected? (2:25) (3) How
Adapting to an acid ocean
Posted on the EPOCA blog 17 May 2011 Acidification has been called the ‘evil twin’ of warming waters when it comes to climate change’s impacts on the ocean. The ocean has become 30% more acidic since the industrial revolution, a trend that is expected to have devastating impacts on corals
Effects of changing pCO2 and phosphate availability on domoic acid production and physiology of the marine harmful bloom diatom Pseudo-nitzschia multiseries
Posted on the EPOCA blog 16 May 2011 Some members of the diatom genus Pseudo-nitzschia produce the toxin domoic acid (DA), which through trophic transfer causes mass mortalities of wildlife, shellfish harvesting closures, and risks to human health. Nutrient and micronutrient limitation have been shown to regulate DA production. This
First national meeting for U.S. ocean acidification researchers
Posted on the EPOCA blog: 12 May 2011 First National Meeting for U.S. Ocean Acidification Researchers — Sarah Cooley, WHOI; Joan Kleypas, NCAR A milestone was reached this spring toward building a strong ocean acidification (OA) research community in the U.S., when the first workshop for U.S. OA researchers was
