Collaborative Research: REU site in Dominica, West Indies: Integrated Examination of Dynamic Volcanic Systems Using Field Volcanology, Satellite Geodesy, and Modeling

REU网站包括在西印度群岛多米尼加岛的实地考察(4周)，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周的相关实地考察。一半的学生将在加州大学做实地考察后的工作，另一半的学生将在CSUSB学习。这些技术包括实地火山学、全球定位系统(GPS)大地测量、简单的定量建模和实验室研究，包括火山岩、沉积物和地热场地水的岩石学和地球化学。目标是培养对岩浆系统、火山监测和灾害评估感兴趣的本科生的研究、科学和技术技能。学生将与一名合作伙伴一起进行实地研究，并制定个人项目，以便在为期4周的后实地考察期间进行补充学习。研究项目包括：利用全球定位系统大地测量限制地表变形；确定个别火山的特征行为；火山碎屑流的颗粒分析和建模；地热系统的地球化学分析；以及研究火山活动和地表变形与区域构造的关系。REU学生将在田野季节结束时准备向当地岛屿观众和多米尼克灾害协调员办公室介绍他们的成果。他们还将参加为期8周结束时的一次为期一天的研究专题讨论会(UA和CSUSB之间的视频会议)、在UA(1岁和3岁)或CSUSB(2年级)举行的年中会议和一次全国会议。正在崛起的物理专业的大三和大四学生将在全国范围内招聘，重点是在HIS和HBCU的招聘，我们在那里有个人联系。由于火山学的多样性，直接研究各种过程和产品是可能的。因此，学生将获得广泛的研究经验，这些经验可能适用于世界各地的其他火山系统。三年期间的综合成果将大大提高对多米尼克火山灾害的了解，以及对整个复杂的安山岩岩浆系统的了解。多米尼加没有大学，这一区域联盟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显著不同的文化。考虑到目前对地球望远镜的投资，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.
