This post is part of the research project: Northwest Ocean Acidification In this blog series, we’ve explained how carbon dioxide pollution is making the oceans more acidic, demonstrated that it’s happening now, looked at which marine
Comparing the impact of high CO2 on calcium carbonate structures in different marine organisms
Posted on EPOCA: 04 Sep 2011 Coastal seas are critical components of the global carbon cycle, yet little research has been conducted on the impact of ocean acidification on coastal benthic organisms. Calcifying marine organisms are predicted to be most vulnerable to a decline in oceanic pH (ocean acidification) based
