This grant funds a continuation of the UMN Research Experience for Undergraduates (REU) site for field, analytical experimental, and theoretical study of geological fluids. Since 1998, the 10 week UMN summer intern program in 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 primarily in karst and fractured rock aquifers, 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 rheology 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 two 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, in order to help develop communication between the students and an appreciation for the broad range of problems that can be addressed with the same experimental, analytical and computational tools.

这项赠款资助了本科生（REU）网站的UMN研究经验的延续，用于地质流体的现场，分析实验和理论研究。自1998年以来，《地质与地球物理学》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十四名本科生。学生将研究地球上流体的共同主题的主题。 They will be involved in various research activities, including the impacts of human activities on groundwater quality primarily in karst and fractured rock aquifers, 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 rheology of mantle rocks, and使用科学可视化等地幔对流和核心动态的数值动手经验等等。该程序具有许多促进队列体验的属性。尤其是，实习生参加了每周的一系列讲座，由参与教职员工和两次研讨会，在其中向彼此和部门成员解释了他们的项目和结果。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，该计划包括野餐，超级湖上的划船和露营之旅等周末活动。计划活动强调了在不同的研究领域进行的研究的联系和通用性，以帮助发展学生之间的沟通以及对可以使用相同的实验，分析和计算工具解决的广泛问题的欣赏。
