REU Site: River and Coastal Restoration

这个nsf资助的本科生研究项目？REU地点：河流和海岸修复？涉及10名学生与国家地表动力学中心（NCED） （www.nced.umn.edu）的科学家和工程师进行为期10周的前沿研究，研究两组关键的环境恢复问题。NCED是一个由nsf资助的科学技术中心。学生分成两个小组，？团队δ?关注路易斯安那沿海地区的问题还是？团队土拨鼠吗?关注与2007年拆除俄勒冈州土拨鼠大坝有关的问题？桑迪河。两个团队六月都在明尼苏达大学的圣安东尼福尔斯实验室（SAFL） （www.safl.umn.edu），使用实验模型来理解他们将在该领域探索的过程。他们还会提出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月进行实地研究，一个团队在路易斯安那州沿海；另一个在桑迪河上。然后，两个团队回到明尼苏达大学，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。土拨鼠小组参与了一项正在进行的运动，以记录2007年土拨鼠大坝拆除后桑迪河的地貌反应。NCED的研究人员与州和联邦机构合作，使用高分辨率的测量方法编制了一份详细的记录，记录了河流如何重新分配以前被困在50英尺高的土拨鼠大坝后面的沉积物。这种规模的沉积物再分配对生态栖息地具有重要意义，特别是对鲑鱼物种。该项目提供了一个真实世界的实验，对于开发更有效的河流管理和恢复实践至关重要。（www.marmotdam.com）三角洲小组参与与密西西比河三角洲海岸恢复有关的研究。数控吗?年代蜡湖现场实验室提供了一个极好的机会来检查在沿海地貌与生态恢复上下文之间的联系。在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.
