Collaborative Research: REU Site in Dominica, West Indies: Integrated examination of dynamic volcanic systems using field volcanology, satellite geodesy, and modeling

REU项目包括在西印度群岛的多米尼加岛进行为期4周的实地考察，以及在阿肯色大学（UA）或加州州立大学圣贝纳迪诺分校（CSUSB）进行为期4周的实地考察后研究。一半的学生将在亚利桑那大学进行实地考察，另一半将在中南大学进行实地考察。这些技术是野外火山学、全球定位系统（GPS）大地测量学、简单的定量建模和实验室研究，包括火山岩、沉积物和地热地点的水的岩石学和地球化学。目标是培养对岩浆系统、火山监测和危险评估感兴趣的本科生的研究、科学和技术技能。学生将与合作伙伴一起进行实地研究，并在实地考察后的4周内开发个人项目进行额外的学习。研究项目包括：利用GPS大地测量法约束地表变形；确定单个火山的特征行为；火山碎屑流的颗粒分析与模拟地热系统地球化学分析；考察火山活动与地表变形与区域构造的关系。REU的学生将在实地季节结束时准备向当地岛屿听众和多米尼加灾害协调员办事处介绍他们的成果。他们还将在8周结束时参加为期1天的研究研讨会（UA和CSUSB之间的视频会议）；在UA（第1年和第3年）或CSUSB（第2年）的年中会议和全国会议。我们将在全国范围内招募物理科学专业的大三和大四学生，重点在我们有个人联系的HIS和HBCU进行招聘。由于火山学的多样性，直接研究各种过程和产物是可能的。因此，学生将获得广泛的研究经验，可以应用于全球其他火山系统。3年期间的综合结果将大大提高对多米尼加火山危险性和一般复杂安山岩岩浆系统的认识。多米尼加没有大学，这个应急小组为灾害协调员办公室提供了宝贵的援助。此外，REU将使美国本科生接触到一种与他们自己的文化相似，但仍有很大不同的文化。考虑到目前对Earthscope的投资，火山系统的REU是及时的。

The REU site includes fieldwork on the island of Dominica in the West Indies (4 weeks) and associated post-fieldwork studies for 4 weeks at either the University of Arkansas (UA) or California State University, San Bernardino (CSUSB). Half of the students will do post-fieldwork at UA and half at CSUSB. The techniques are field volcanology, Global Positioning System (GPS) geodesy, simple quantitative modeling and laboratory studies, including petrology and geochemistry of volcanic rocks, sediments and waters from geothermal sites. The objectives are to develop research, scientific, and technical skills in undergraduate students who are interested in magmatic systems, volcano monitoring, and hazard assessment. Students will be paired with a partner for field research and develop individual projects for additional study for the 4 week post-fieldwork period. Research projects include: constraining surface deformation using GPS geodesy; identifying the characteristic behavior of individual volcanoes; particle analysis and modeling of pyroclastic flows; geochemical analysis of geothermal systems; and examination of the relationship between volcanism and surface deformation to regional tectonics. The REU students will prepare presentations on their results to local island audiences and the Office of the Disaster Coordinator of Dominica at the end of their field seasons. They will also participate in a 1-day research symposium at the end of the 8-weeks (videoconferenced between UA and CSUSB); a mid-year conference at either UA (years 1 and 3) or CSUSB (year 2) and a national meeting. Rising juniors and seniors with majors in the physical sciences will be recruited nationally with focused recruitment at HIS's and HBCU's where we have personal contacts. Because of the volcanological diversity, direct study of a variety of processes and products is possible. Students will thus receive broad-based research experience that may be applied to other volcanic systems worldwide. Integrated results over the 3-year period will significantly improve understanding of volcanic hazard in Dominica and of complex andesitic magmatic systems in general. Dominica has no university and this REU brings invaluable assistance to the Office of the Disaster Coordinator. In addition, the REU will expose U.S. undergraduates to a culture similar to their own, but still significantly different. An REU in volcanic systems is timely, given the current investment in Earthscope.
