“Global climate change: ocean acidification experiments at CO2 vents”, 2015 Aquatic Sciences Meeting, 22-27 February 2015, Granada, Spain

The abstract submission deadline is 23:59 U.S. Central Daylight Time on Friday, 10 October 2014.

Ocean acidification (OA) has raised concerns about its effects on marine organisms, particularly for those reliant on the generation and accumulation of calcium carbonate (CaCO3) shells, tests, skeletons, and/or structures. As a consequence of OA, the ability of marine calcifiers to deposit CaCO3 is modified in response to changes in ocean geochemistry as carbonate ions are an essential substrate for biotic calcification. Most studies investigating how elevated CO2 will impact the function of marine organisms are laboratory-based, making it difficult to directly relate laboratory results to the effect that elevated CO2 will have on marine biota in situ. Field experiments, at sites with naturally-elevated CO2 conditions, such as CO2 vents, are potentially useful analogues for investigating the effect of future acidification on marine organisms and ecosystems. Vents are not ideal predictors of future oceans, owing to pH variability but they acidify seawater on sufficiently large temporal and spatial scales to integrate ecosystem processes, acting as “natural laboratories.” This session is intended to provide a summary of the main findings obtained from field-based studies and provide key lessons on the long-term effects of ocean acidification on marine ecosystems acclimatized to high pCO2.
