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.

明尼苏达大学已获得NSF奖，以支持明尼苏达州明尼阿波利斯的地球科学的本科生研究经验（REU）的延续。自1998年以来，地质和地球物理学系的10周UMN暑期实习计划一直集中在有关从地面和近地面系统到地幔到核心的地质流体的研究。每年将在全国范围内招募来自不同背景的14名本科生。学生将研究地球上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，对湖泊了解区域环境动态的林姆地质研究，评估流体在变质和火成岩系统中的化学和机械效应，对液体和熔体的地震检测在地球的地幔中，使用科学可视化等等，融化对地幔岩石变形的影响以及在地幔对流和核心动力学方面的数字动手体验等等。该程序具有许多促进队列体验的属性。特别是，实习生参加了每周由参与教职员工和座谈会提供的一系列讲座，他们在其中彼此和部门成员向彼此解释了他们的项目和结果。该计划通过每周期刊和案例研究回应评估了REU对实习生对科学本质的看法的影响。 长期对其职业道路的影响将通过退出和纵向问卷进行评估。此外，他们还接触了夏季研究以外的学科，并通过参加中西部地点的实地考察（洞穴，冰川湖/河流特征，中大陆的裂谷熔岩，深层地下观测站）。实习计划的一个重要目标是将实习生纳入地质和地球物理学系的研究环境中，允许与该系的各个研究小组中的教职员工，毕业后和研究生进行互动。该计划在与未来的地球科学同事和朋友互动时，还激发了夏季学生的社区感。实习生居住在大学住房中，有连续的房间任务和共享的烹饪设施，该计划包括周末活动，例如野餐，在苏必利尔湖上划船和露营旅行。计划活动强调了不同研究领域进行的研究的联系和共性。
