REU Site: Fluids in the Earth from Surface to Core

明尼苏达大学被授予NSF奖，以支持明尼苏达州明尼阿波利斯市的本科生研究经验(REU)地球科学网站的继续。自1998年以来，UMN暑期实习生计划为期10周。地质和地球物理学研究所的工作重点是研究从地表和近地表系统到地幔再到核心的地质流体。每年将在全国范围内招收14名不同背景的本科生。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，对湖泊的湖泊地质研究，以了解区域环境动力学，评估变质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，熔融对地幔岩石变形的影响，以及利用科学可视化对地幔对流和核心动力学的实际数值体验，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训教师讲授的讲座，并参加座谈会，向彼此和系里的成员解释他们的项目和结果。该计划通过每周期刊和案例研究回应来评估这种REU对实习生对科学本质的感知的影响。对他们职业道路的长期影响将通过离职问卷和纵向问卷进行评估。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。方案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.
