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.

REU网站包括在西印度群岛的多米尼加岛的实地考察（4周）和相关的实地考察后的研究4周在阿肯色州（UA）或加州州立大学，圣贝纳迪诺（CSUSB）的大学。一半的学生将在UA和CSUSB的一半做后实地考察。这些技术是野外火山学、全球定位系统大地测量、简单的定量建模和实验室研究，包括火山岩、沉积物和地热点沃茨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。学生将与合作伙伴配对进行实地研究，并在4周的实地考察后开发个人项目进行额外的研究。研究项目包括：这些项目包括：利用GPS大地测量限制地表变形;确定各火山的特征行为;火山碎屑流的颗粒分析和建模;地热系统的地球化学分析;以及火山活动和地表变形与区域构造之间的关系的研究。 REU学生将准备在他们的实地季节结束时向当地岛屿观众和多米尼加灾害协调员办公室介绍他们的成果。 他们还将在8周结束时参加为期一天的研究研讨会（UA和CSUSB之间的视频会议）;在UA（第1年和第3年）或CSUSB（第2年）和全国会议的年中会议。 物理科学专业的大三和大四学生将在全国范围内招募，重点是在我们有个人联系的HIS和HBCU进行招募。 由于火山的多样性，可以直接研究各种过程和产物。因此，学生将获得广泛的研究经验，可应用于世界各地的其他火山系统。 三年期间的综合结果将大大提高对多米尼加火山灾害和复杂的安山岩浆系统的总体认识。 多米尼克没有大学，这所REU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与他们自己相似但仍显着不同的文化。考虑到目前对“地球镜”的投资，在火山系统中进行REU是及时的。
