Posted on OA: 19 May 2014 Decreases in ocean pH through ocean acidification has shown to have direct negative impacts on the early life stages of the Pacific purple sea urchin, Strongylocentrotus purpuratus. Research has suggested that multiple stressors could exacerbate, cancel, or even alleviate the impacts of ocean acidification

Ocean Acidification Threatens Sea Life
Posted on CCTV America: 16 May 2014 — Interview with Todd Capson by Anand Naidoo The world’s seafood supply could be in jeopardy. Why? Ocean acidification. It’s the process in which the pH level in seawater is lowered through the absorption of carbon dioxide (CO2) from the atmosphere. Changes to
Evaluating the impact of ocean acidification on fishery yields and profits: The example of red king crab in Bristol Bay
Posted on OA: 15 May 2014 — Punt A. E., Poljaka D., Dalton M. G. & Foy R. J., 2014. . Ecological Modelling 285:39-53 A stage-structured pre-recruit model was developed to capture hypotheses regarding the impact of ocean acidification on the survival of pre-recruit crab. The model was parameterized using
Examining How Marine Life Might Adapt to Acidified Oceans
Posted on Yale Environment 360: 14 May 2014 — By Elizabeth Grossman — In an interview with Yale Environment 360, marine biologist Gretchen Hofmann discusses how well mollusks and other shell-building organisms might evolve to live in increasingly corrosive ocean conditions caused by soaring CO2 emissions. As the world’s oceans
Uranium in larval shells as a barometer of molluscan ocean acidification exposure
Posted on OA: 12 May 2014 — Frieder C. A., Gonzalez J. P. & Levin L. A., in press. Environmental Science & Technology. As the ocean undergoes acidification, marine organisms will become increasingly exposed to reduced pH, yet variability in many coastal settings complicates our ability to accurately estimate pH
