Posted on EPOCA: 14 Dec 2011 Anthropogenic carbon dioxide (CO2) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms and thereby modifying the oceanic alkalinity cycle. However, the responses of pelagic calcifying organisms to acidification vary widely between species, contributing uncertainty to predictions of atmospheric CO2 and the resulting

By Ryan Jacobs Courtesy of Charles O’Kelly Once in a great while, a biologist finds herself at the confluence of a rare natural phenomenon. This often involves decades, or even whole careers, of observing and
AGU Fall Meeting: the (pH) lowdown on ocean acidification
Posted on EPOCA: 12 Dec 2011 Ocean acidification is often overlooked as a problem in favour of its more famous parent, climate change. But it’s receiving plenty of attention at the AGU Fall Meeting in San Francisco. Whilst most information on the effects of acidification is based on modelling or
Ocean Acidification – Research notes from the School of Aquatic and Fishery Sciences
Posted on EPOCA: 12 Dec 2011 This website has been developed to serve as a portal for information on active research on ocean acidification within the School of Aquatic and Fishery Sciences at the University of Washington. Project highlights are provided below with occasional posts found in the adjacent column.
Acidic oceans threaten fish
By Hannah Hoag, posted 11 December 2011 — Stocks could suffer as seas soak up more carbon dioxide. Caption: Fish could be most susceptible to carbon dioxide when in the egg, or just hatched. HANNES BAUMANN Ocean acidification — caused by climate change — looks likely to damage crucial fish
