Long-term and trans-life-cycle effects of exposure to ocean acidification in the green sea urchin Strongylocentrotus droebachiensis
Posted on EPOCA: 31 Mar 2012 Anthropogenic CO2 emissions are acidifying the world’s oceans. A growing body of evidence demonstrates that ocean acidification can impact survival, growth, development and physiology of marine invertebrates. Here, we tested the impact of long-term (up to 16 months) and trans-life-cycle (adult, embryo/larvae and juvenile) exposure to
Detection and projection of carbonate dissolution in the water column and deep-sea sediments due to ocean acidification
Posted on EPOCA: 31 Mar 2012 Dissolution of fossil fuel CO2 in seawater results in decreasing carbonate ion concentration and lowering of seawater pH with likely negative impacts for many marine organisms. We project detectable changes in carbonate dissolution and evaluate their potential to mitigate atmospheric CO2 and ocean acidification with a
High temporal and spatial variability of dissolved oxygen and pH in a nearshore California kelp forest
Posted on EPOCA: 31 Mar 2012 Predicting consequences of ocean deoxygenation and ocean acidification for nearshore marine ecosystems requires baseline dissolved oxygen (DO) and carbonate chemistry data that are both high-frequency and high-quality. Such data allow accurate assessment of environmental variability and present-day organism exposure regimes. In this study, scales
EPOCA comes to an end, Project Office relocated
Posted on EPOCA: 31 Mar 2012 The European Project on Ocean Acidification (EPOCA) will come to an end on 30 June 2012. Thanks to generous support of a Côte d’Azur billionaire, its activities will be continued and the Project Office relocated in the eco-friendly premises shown here.
