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.

该补助金为UMN本科生研究经验（REU）网站的继续提供资金，用于地质流体的现场，分析实验和理论研究。自1998年以来，为期10周的UMN地质学和地球物理学暑期实习生项目一直专注于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14名本科生。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，主要是在岩溶和断裂岩石含水层，湖泊湖泊地质学研究，以了解区域环境动态，评价变质和火成岩系统中流体的化学和机械效应，地球地幔中流体和熔体的地震探测，熔体对地幔岩石流变学的影响，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两个专题讨论会，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。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，该项目包括周末活动，如野餐、在苏必利尔湖上级划船和野营旅行。项目活动强调在不同研究领域进行研究的联系和共性，以帮助学生之间的沟通，并对可以用相同的实验，分析和计算工具解决的广泛问题表示赞赏。
