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未来生态系统的功能和服务将如何变化。在这个项目中，该研究员将评估在未来海洋pH和温度条件下，pH变化对一种具有生态和经济重要性的贻贝物种的影响。这项研究将在法国南维尔弗利奇实验室与国际主办科学家Jean-Pierre Gattuso博士和赞助科学家Todd Martz博士(美国斯克里普斯海洋研究所)合作进行。通过举办研讨会，这位研究员将向欧洲学生和科学家介绍pH传感器，并促进在生物实验设计中使用现场数据。该项目支持培训一名博士后研究员和两名本科生实习生。该项目的结果和数据将在会议上和通过开放获取的出版物和数据储存库传播。调查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值的时空变异性。在未来的酸化程度下，这种pH值的不均一性可能提供暂时的避难所，使其免受腐蚀性海水的侵害。利用野外和实验室实验相结合的方法，该项目将通过多个生物组织水平来评估pH值变化以及变暖和酸化对贻贝生理的影响。如果pH的变化对贻贝的发育和生长产生有利影响，该项目的结果将为沿海地区海洋酸化的地方管理和水产养殖实践提供一条途径。

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.
