OCE PRF: Track 2 (International) Indirect effects in a changing ocean: a case study of seagrass photosynthesis and mussel physiology

海洋酸化研究的主要目标之一是了解生态系统功能和服务在未来将如何变化。在这个项目中，研究员将评估在未来海洋pH值和温度条件下，pH变化对生态和经济上重要的贻贝物种的影响。这项研究将在法国滨海维勒弗朗什的ocacimanographie实验室与国际主持科学家Jean-Pierre Gattuso博士和赞助科学家Todd Martz博士（美国斯克里普斯海洋学研究所）合作进行。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，并在生物实验设计中推广实地数据的使用。本项目支持培养1名博士后和2名本科生实习生。该项目的结果和数据将在会议上以及通过开放获取的出版物和数据存储库传播。研究海洋酸化对海洋生物影响的实验往往忽略了沿海海洋生态系统中存在的海水pH值的时空变化。在未来的酸化水平下，这种pH值的不均匀性可能为腐蚀海水提供暂时的庇护。利用野外和实验室实验相结合的方法，该项目将通过几个生物组织水平来评估pH变化的影响以及升温和酸化对贻贝生理的相互作用。如果pH值的变化对贻贝的发育和生长有有益的影响，该项目的结果为沿海地区和水产养殖做法的地方海洋酸化管理提供了一条途径。

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.
