One of the major goals of ocean acidification research is to understand how ecosystem functioning and services will change in the future. In this project, the fellow will assess the influence of pH variability on an ecologically and economically important mussel species, under future ocean pH and temperature conditions. The research will be conducted at Laboratoire d'Océanographie de Villefranche-sur-Mer, France in collaboration with international host scientist Dr. Jean-Pierre Gattuso and sponsoring scientist Dr. Todd Martz (Scripps Institution of Oceanography, USA). By hosting a workshop, the fellow will introduce pH sensors to European students and scientists and promote the use of field data in the design of biological experiments. The project supports the training of a postdoctoral fellow and two undergraduate student interns. Results and data from this project will be disseminated at conferences and through open-access publications and data repositories.Experiments investigating the effects of ocean acidification on marine organisms often ignore the spatio-temporal variability in seawater pH that is present in coastal marine ecosystems. Such heterogeneity in pH may provide temporal refuge from corrosive seawater under future levels of acidification. Utilizing a combination of field and lab experiments, this project will evaluate the influence of pH variability and interactive effects of warming and acidification on mussel physiology through several levels of biological organization. Should variability in pH provide beneficial effects on mussel development and growth, results of the project provide an avenue for local management of ocean acidification in coastal regions and aquaculture practices.

海洋酸化研究的主要目标之一是了解生态系统的功能化和服务将来将如何变化。在这个项目中，研究员将在未来的海洋pH和温度条件下评估pH变异性对生态和经济上重要的贻贝物种的影响。这项研究将在法国与国际主持人科学家让·皮埃尔·加图索（Jean-Pierre Gattuso）博士和赞助科学家托德·马茨（Todd Martz）博士（美国海洋学研究所）合作，在法国Laboratoired'Océanogrageiede Villefranche-Sur-Mer进行。通过举办研讨会，该研究员将向欧洲学生和科学家介绍pH传感器，并在生物学实验设计中促进现场数据的使用。该项目支持博士后研究员和两名本科生实习生的培训。该项目的结果和数据将在会议和开放式出版物和数据存储库中传播。研究海洋酸化对海洋生物的影响通常忽略了沿海海洋生态系统中存在的海水pH值。 pH中的这种异质性可能在未来的酸化水平下提供腐蚀性海水的临时避难所。利用现场和实验室实验的结合，该项目将通过几个生物组织的多个级别来评估pH变异性和变暖和酸化对贻贝生理的影响的影响。如果pH的变异性对肌肉发育和增长产生有益的影响，该项目的结果为沿海地区和水产养殖实践中海洋酸化的局部管理提供了途径。
