BIOACID
Biological Impacts Of Ocean Acidification
The growing evidence of potential biological impacts of ocean acidification affirms that this global change phenomenon may pose a serious threat to marine organisms and ecosystems. Despite a wealth of knowledge on specific effects of acidification and the related changes in seawater chemistry on the physiology of individual marine taxa, many uncertainties still remain. Because the majority of studies are based on single species experiments, little is presently known about possible impacts on natural communities, food webs and ecosystems. Moreover, few studies have addressed possible interacting effects of environmental changes occurring in parallel, such as ocean acidification, warming, and deoxygenation and changes in surface layer stratification and nutrient supply. Almost completely unknown at present is the potential for evolutionary adaptation to ocean acidification.To pave the way for a more encompassing assessment of future biological responses to ocean change and their possible socio-economic consequences, the second phase of BIOACID will
- strengthen the integration within the BIOACID community to allow for more realistic community-level experimentation and field observation
- focus more strongly on interacting affects through multiple stressors
- expand evolutionary biology to assess the potential for adaptation of key taxa
- integrate socio-economic assessments and stakeholder involvement
The second phase of BIOACID began in September 2012 and will last three years.
The Federal Ministry of Education and Research (BMBF) supports the project that is coordinated by GEOMAR Helmholtz Centre for Ocean Research Kiel with 8.77 million Euros.
