REU Site: River and Coastal Restoration

这个由NSF赞助的本科生研究项目？REU网站：河流和海岸恢复，？10名学生与国家地球表面动力学中心(NCED)(www.nced.umn.edu)的科学家和工程师就两组关键的环境恢复问题进行了为期10周的前沿研究。NCED是NSF资助的科学和技术中心。学生们在两个团队中的一个团队工作，三角洲团队？专注于路易斯安那州沿海地区的问题，还是旱獭团队？聚焦于2007年俄勒冈州S沙河旱獭大坝拆除的相关问题。两个团队都在明尼苏达大学的圣安东尼瀑布实验室(SAFL)(www.Safl.umn.edu)度过了6月份，使用实验建模来了解他们将在现场探索的过程。他们还开发自己的实地研究问题，并在6月份参加科学写作、研究和伦理研讨会。然后，这些团队在7月份进行实地研究，一个团队在路易斯安那州沿海地区；另一个团队在桑迪河上。然后，两个团队都回到明尼苏达大学，在海报和论文中综合他们的研究。学生们在SAFL夏季研究研讨会和校园内更大的跨学科海报会议上分享他们的海报。旱獭团队参与了一项正在进行的活动，记录沙河对2007年旱獭大坝拆除的地貌反应。NCED的研究人员与州和联邦机构合作，使用高分辨率测量方法编制了一份详细的记录，记录了这条河是如何重新分配以前被困在50英尺高的旱獭大坝后面的沉积物的。这种规模的沉积物再分配对生态栖息地有重要影响，在这种情况下，尤其是鲑鱼物种。该项目提供了一个现实世界的实验，对开发更有效的河流管理和恢复实践至关重要。(www.marmotdam.com)Delta团队参与与密西西比河三角洲海岸恢复相关的研究。S蜡湖野外实验室提供了一个极好的机会，在海岸恢复的背景下研究地貌和生态之间的联系。三角洲平原的其他历史实地研究领域为学生提供了将短期项目整合到地貌、生物地球化学和生态过程的长期视角中的机会。(http://www.wbi.lsu.edu))

This NSF-sponsored undergraduate research program ?REU Site: River and Coastal Restoration,? involves 10 students for 10 weeks of cutting-edge research on two sets of critical environmental restoration problems with scientists and engineers of the National Center for Earth-surface Dynamics (NCED) (www.nced.umn.edu), an NSF-funded Science and Technology Center. Students work on one of two teams, ?Team Delta? focused on issues in coastal Louisiana or ?Team Marmot? focused on issues related to the 2007 removal of the Marmot dam on Oregon?s Sandy River. Both teams spend June at the St. Anthony Falls Laboratory (SAFL) (www.safl.umn.edu), at the University of Minnesota, using experimental modeling to develop an understanding of the processes they will explore in the field. They also develop their field research questions and participate in scientific writing, research, and ethics seminars in June. The teams then perform field research in July, one team in coastal Louisiana; the other on the Sandy River. Both teams then return to the University of Minnesota to synthesize their research in posters and papers. Students share their posters at the SAFL summer research symposium and at a larger, interdisciplinary poster session on campus.Team Marmot participates in an ongoing campaign to document the geomorphic response of the Sandy River to the 2007 removal of the Marmot Dam. NCED research staff, in collaboration with state and federal agencies, use high resolution measurements to compile a detailed record of how the river redistributes sediment formerly trapped behind the 50 ft tall Marmot dam. Sediment redistribution of this magnitude has important implications for ecological habitat, in this case for salmonid species in particular. This project provides a real-world experiment, critical to the development of more effective river management and restoration practices. (www.marmotdam.com)Team Delta participates in research related to coastal restoration of the Mississippi River Delta. NCED?s Wax Lake field laboratory presents an excellent opportunity to examine linkages between geomorphology and ecology in a coastal restoration context. Additional historical field research areas in the deltaic plain provide students the opportunity to integrate short term projects into a longer-term perspective of geomorphic, biogeochemical, and ecological processes.
