Technical descriptionDrs. Sibel Bargu, Department of Oceanography and Coastal Sciences, Louisiana State Universityand Nihayet Bizsel, Institute of Marine Sciences and Technology, Dokuz Eylul University, Turkeyhave initiated a new international collaboration to study questions relating to the influence of nutrients and temperatures on phytoplankton dynamics. The focus is on changes in phytoplankton diversity, the related functions, and productivity in space and time with the goal to understand the impact of climate change on coastal marine ecosystems. The sites selected for comparative study are two subtropical, eutrophic coastal regions in the Gulf of Mexico, and the Aegean Sea. Aquatic systems are exposed to a variety of impacts that originate from both natural and human-induced stressors. With climate change, the temporal and spatial growth conditions for primary producers and their species-specific adaptations will be altered in coastal waters around the world. Although similar hydrological environments in different oceans are expected to have similar phytoplankton assemblages, human induced and climate related stressors such as: changes in nutrient bioavailability and increase in temperature could yield geographic differences in phytoplankton species and genetic diversity, their productivity, and other associated functions in their environment. The Izmir Bay and Louisiana Coastal waters are the selected sites for improving understanding of the eco-physiological mechanisms that determine ecosystem responses to natural or anthropogenic stressors within the context of phytoplankton ecology. Broader descriptionComparing the similarities and dissimilarities of the two systems in the context of phytoplankton ecology offers significant opportunities to understand the impact of climate change on coastal marine ecosystems. Beyond the scientific contributions, the project will initiate a promising, new bilateral collaboration with Turkish researchers, offer a unique international research opportunity to an undergraduate student from Louisiana State University, and will contribute significantly to the development of a follow-on large-scale, multidisciplinary research project that will be submitted to the Biological Oceanography Program in GEO/Ocean Sciences.

技术说明Drs.路易斯安那州立大学海洋学和海岸科学系的 Sibel Bargu 和土耳其 Dokuz Eylul 大学海洋科学与技术研究所 Nihayet Bizsel 发起了一项新的国际合作，以研究与营养物和温度对浮游植物动态影响相关的问题。重点关注浮游植物多样性、相关功能和生产力在时空上的变化，旨在了解气候变化对沿海海洋生态系统的影响。选择进行比较研究的地点是墨西哥湾和爱琴海的两个亚热带富营养化沿海地区。水生系统面临着来自自然和人为压力源的各种影响。随着气候变化，世界各地沿海水域初级生产者的时空生长条件及其特定物种的适应将发生改变。尽管不同海洋中相似的水文环境预计会有相似的浮游植物组合，但人类引起的和与气候相关的压力源，例如：养分生物利用度的变化和温度的升高可能会导致浮游植物物种和遗传多样性、生产力和其他相关功能的地理差异。在他们的环境中。伊兹密尔湾和路易斯安那州沿海水域是为了提高对生态生理机制的了解而选择的地点，这些机制决定了浮游植物生态背景下生态系统对自然或人为压力源的反应。更广泛的描述在浮游植物生态学的背景下比较两个系统的相似性和不同点为了解气候变化对沿海海洋生态系统的影响提供了重要的机会。除了科学贡献之外，该项目还将与土耳其研究人员开展一项有前途的新双边合作，为路易斯安那州立大学的本科生提供独特的国际研究机会，并将为后续大规模、将提交给GEO/海洋科学生物海洋学计划的多学科研究项目。
