REU Site: Fluids in the Earth from Surface to Core

这笔资金用于继续UMN本科生研究经验(REU)现场、分析实验和地质流体理论研究。自1998年以来，UMN为期10周的地质和地球物理暑期实习生项目一直专注于从地表和近地表系统到地幔再到核心的地质流体研究。每年将面向全国招收14名本科生。学生们将研究以地球流体为共同主题的主题。他们将参与各种研究活动，包括人类活动对地下水质量的影响，主要是在岩溶和裂隙岩石含水层；对湖泊进行湖泊地质研究，以了解区域环境动态；评估变质岩和火成岩系统中流体的化学和机械影响；地震探测地球地幔中的流体和熔体；熔融对地幔岩石流变学的影响；以及利用科学可视化进行地幔对流和岩心动力学方面的实际数值体验，以及更多。该计划有许多特点，可以培养一种队列体验。具体地说，实习生每周参加一系列由参与教师讲授的讲座，并参加两次座谈会，向彼此和系里的成员解释他们的项目和结果。此外，他们还接触了夏季研究之外的学科，并参加了对中西部遗址(洞穴、冰川湖泊/河流地貌、中大陆裂谷熔岩、深层地下天文台)的实地考察。实习计划的一个重要目标是将实习生融入系内的研究环境。地质学和地球物理学，允许与该系不同研究小组的教师、博士后和研究生进行互动。该计划还培养了暑期学生在与未来的地球科学同事和朋友互动时的社区意识。实习生住在大学宿舍，分配的房间相连，共用烹饪设施，该计划包括周末活动，如野餐、在苏必利尔湖划船和露营旅行。计划活动强调在不同研究领域开展的研究的联系和共性，以帮助学生之间的交流，并认识到可以用相同的实验、分析和计算工具解决的广泛问题。

This grant funds a continuation of the UMN Research Experience for Undergraduates (REU) site for field, analytical experimental, and theoretical study of geological fluids. Since 1998, the 10 week UMN summer intern program in Geology and Geophysics has focused on research concerning geological fluids from surface and near-surface systems to the mantle to the core. Fourteen undergraduate students will be recruited nationally each year. The students will investigate topics with the common theme of fluids in the Earth. They will be involved in various research activities, including the impacts of human activities on groundwater quality primarily in karst and fractured rock aquifers, limnogeology research on lakes to understand regional environmental dynamics, evaluation of the chemical and mechanical effects of fluids in metamorphic and igneous systems, seismic detection of fluids and melts in Earth's mantle, the effect of melt on rheology of mantle rocks, and numerical hands-on experience with mantle convection and core dynamics using scientific visualization, and more. The program features many attributes that foster a cohort experience. In particular, interns participate in a weekly series of lectures given by participating faculty and in two symposia in which they explain their projects and results to each other and to members of the department. In addition, they are exposed to disciplines outside their summer research and by participating in field trips to Midwestern sites (caves, glacial lake/river features, mid-continent rift lavas, deep underground observatories). An important goal of the internship program is to integrate the interns into the research environment of the Dept. of Geology and Geophysics, allowing interactions with faculty, post-docs, and graduate students in the various research groups of the department. The program also fosters a sense of community among the summer students as they interact with future Earth science colleagues and friends. Interns live in university housing with contiguous room assignments and shared cooking facilities and the program includes weekend activities such as picnics, boating on Lake Superior, and camping trips. Program activities emphasize the connections and commonality of research carried out in diverse research fields, in order to help develop communication between the students and an appreciation for the broad range of problems that can be addressed with the same experimental, analytical and computational tools.
