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 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. 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.

明尼苏达大学已获得美国国家科学基金会 (NSF) 奖项，以支持明尼苏达州明尼阿波利斯地球科学本科生研究体验 (REU) 网站的继续开展。自 1998 年以来，UMN 地质与地球物理系为期 10 周的暑期实习项目重点研究从地表和近地表系统到地幔到地核的地质流体。每年面向全国招收本科生14名。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、湖泊湖泊地质学研究以了解区域环境动态、评估变质和火成岩系统中流体的化学和机械效应、流体和熔体的地震探测地幔中的融化对地幔岩石变形的影响，以及使用科学可视化对地幔对流和地核动力学进行数值模拟的实践经验等等。该计划具有许多促进群体体验的特点。特别是，实习生每周都会参加由参与的教师举办的系列讲座和研讨会，在研讨会上他们向彼此和系里的成员解释他们的项目和结果。此外，他们还通过参加夏季研究之外的学科以及参加中西部地区的实地考察（洞穴、冰川湖/河流特征、中部大陆裂谷熔岩、深层地下天文台）。实习计划的一个重要目标是让实习生融入地质与地球物理系的研究环境，与该系各个研究小组的教师、博士后和研究生进行互动。该项目还培养了暑期学生与未来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，分配相邻的房间并共用烹饪设施，该计划包括周末活动，如野餐、苏必利尔湖划船和露营旅行。计划活动强调不同研究领域开展的研究的联系和共性。
