The acid test

Posted on the EPOCA blog: 25 May 2011 — Why ocean acidification matters to you. Every day, the oceans do us a huge favor. Across the planet, they absorb nearly one million metric tons of carbon dioxide each hour, removing about a third of the greenhouse gases from the atmosphere that would otherwise

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
