OC44A:
Chemical and Biological Impacts of Ocean Acidification in the Pacific Ocean III Posters

Session ID#: 84657

Session Description:
Ocean acidification is one of many stressors relevant to ocean ecosystems in a changing climate. In the Pacific Ocean, acidification is occurring in concert with changes in other key processes such as increasing temperature, deoxygenation, changing circulation patterns, changes in nutrient concentrations, and trophic alterations. The nature and magnitude of the impacts from ocean acidification on marine organisms, ecosystems and the biological pump may be different (exaggerated or modulated) when coupled with these other stressors. Understanding these changes and their influence on organisms and ecosystems has the potential to help understand and predict future ecosystem and biogeochemical responses. Furthermore, questions remain regarding the degree to which unexpected or abrupt changes and regime shifts will occur and to what degree and extent the biological and biochemical thresholds would be surpassed. This session will discuss the role of ocean acidification in the context of other stressors, such as temperature, deoxygenation, nutrients enrichment or depletion, taking into consideration the potential for abrupt changes and the role of complex biogeochemical and climatic feedbacks.
