This is a Research Experience for Undergraduates (REU) site for field, analytical experimental, and theoretical study of geological fluids. Research in this program range from surface and near-surface fluid 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, limnogeolgogy research on lakes to understand regional environmental dynamics, evaulation of the chemical and mechanical effects of fluids in metamorphic and igneous systems, the effect of melt on rheology of mantle rocks, and numerical hands-on experience with mantle convection and core dynamics using scientific visualization.The program features many attributes that foster a cohort experience. In particular, interns participate 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 by participating in field trips to Midwestern sites (caves, glacial lake/river features, mid-continent rift lavas), by touring a wide range of laboratory facilities (rock magnetism, isotope geochemistry, rock mechanics, electron microscopy) at the University of Minnesota and vicinity. An important goal of the internship program is to foster a sense of community among the summer students as they interact with future Earth science colleagues and friends, and so the program includes weekend activities such as picnics, boating on Lake Superior, bike rides around the lakes in the Twin Cities, and visits to museums. 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.

这是针对本科，分析实验和地质流体理论研究的本科生（REU）站点的研究经验。 该程序的研究范围从表面和近表面流体系统到地幔到核心。 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。 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，主要是在喀斯特和破裂的岩石含水层中，对湖泊的林格戈尔学研究，以了解区域环境动态，对变质系统中流体的化学和机械作用的变化，使用科学可视化的融化对地幔岩石的风化的影响以及在地幔对流和核心动态方面的数字动手体验。该程序具有许多促进队列体验的属性。 特别是，实习生参与了两次研讨会，在其中向彼此和部门成员解释了他们的项目和结果。 此外，通过参观广泛的实验室设施（岩石磁化，同位素地球，岩石地理位置，他们都参与了夏季研究（洞穴，冰川湖/河流特征，中大陆熔岩），他们通过夏季研究以外的学科接触了学科。 ，明尼苏达大学和附近的岩石力学，电子显微镜）。 实习计划的一个重要目标是在夏季学生与未来的地球科学同事和朋友互动时培养一种社区感，因此该计划包括周末活动，例如野餐，在苏必利尔湖上划船，湖泊周围的自行车骑车在双子城，参观博物馆。 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。
