REU Site: Fluids in the Earth from Surface to Core

明尼苏达大学获得了美国国家科学基金会的奖励，以支持明尼苏达州明尼阿波利斯市地球科学本科生研究经验（REU）站点的延续。自1998年以来，为期10周的UMN地质与地球物理系暑期实习项目侧重于从地表和近地表系统到地幔再到地核的地质流体研究。每年将招收14名来自不同背景的本科生。学生们将以地球上的流体为共同主题进行研究。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，湖泊的湖泊地质学研究，以了解区域环境动力学，变质和火成岩系统中流体的化学和机械效应的评估，地幔中流体和熔体的地震探测，熔体对地幔岩石变形的影响，以及使用科学可视化技术进行地幔对流和地核动力学的数值实践经验，等等。该项目有许多特点，可以培养学员的体验。特别是，实习生每周都要参加由参与的教员举办的系列讲座，并参加专题讨论会，向彼此和部门成员解释他们的项目和成果。该项目通过周刊和案例研究回应来评估REU对实习生对科学本质的感知的影响。通过退出问卷和纵向问卷来评估对他们职业道路的长期影响。此外，他们还会接触到夏季研究之外的学科，并通过参加中西部地区的实地考察（洞穴、冰川湖/河流特征、大陆中部裂谷熔岩、地下深部观测站）。实习计划的一个重要目标是将实习生融入地质与地球物理系的研究环境，允许与该系各个研究小组的教职员工、博士后和研究生进行互动。这个项目还培养了暑期学生的社区意识，因为他们与未来的地球科学同事和朋友互动。实习生住在大学宿舍，有连续的房间分配和共享烹饪设施，项目包括周末活动，如野餐，在苏必利尔湖划船和露营旅行。项目活动强调在不同研究领域开展的研究的联系和共性。

The University of Minnesota has been granted an NSF award to support the continuation of the Research Experience for Undergraduates (REU) site for geosciences in Minneapolis, Minnesota. Since 1998, the 10 week UMN summer intern program in the Dept. of 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 from diverse background 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, 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 deformation 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 symposia in which they explain their projects and results to each other and to members of the department. The program evaluates the impact of this REU on interns' perception of the nature of science through weekly journals and case study responses. Longer term impact on their career paths will be assessed through exit and longitudinal questionnaires. 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.
