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.

明尼苏达大学已被授予NSF奖，以支持继续在明尼苏达州明尼阿波利斯市的地球科学本科生研究经验（REU）网站。自1998年以来，10周的UMN暑期实习生计划在该部。地质学和地球物理学联合会的工作重点是研究从地表和近地表系统到地幔再到地核的地质流体。每年将在全国范围内招收14名不同背景的本科生。学生们将调查与地球流体的共同主题的主题。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、为了解区域环境动态而对湖泊进行的湖沼地质学研究、变质和火成岩系统中流体的化学和力学效应评价、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的地幔对流和核心动力学的数值实践经验等等。该计划具有许多促进队列体验的属性。特别是，实习生参加由参与教师和研讨会，他们解释他们的项目和结果给对方和部门的成员每周一次的系列讲座。该计划通过每周期刊和案例研究回应评估该REU对实习生对科学本质的看法的影响。 将通过离职和纵向调查问卷评估对他们职业道路的长期影响。此外，他们接触到他们的夏季研究以外的学科，并参加实地考察中西部网站（洞穴，冰川湖/河功能，中大陆裂谷熔岩，深地下观测站）。实习计划的一个重要目标是将实习生融入系里的研究环境。地质学和地球物理学，允许与教师，博士后和研究生在该部门的各个研究小组的互动。该计划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里，房间相邻，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。上级。计划活动强调在不同研究领域进行的研究的联系和共性。
