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 站点包括在西印度群岛多米尼加岛进行的实地考察（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) 进行的为期 4 周的相关实地考察后研究。一半的学生将在 UA 进行实地考察，另一半将在 CSUSB 进行。这些技术包括野外火山学、全球定位系统（GPS）大地测量学、简单的定量模型和实验室研究，包括火山岩、沉积物和地热区水域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，并开发个人项目以在实地考察后 4 周内进行额外研究。研究项目包括：利用 GPS 大地测量学约束地表变形；识别各个火山的特征行为；火山碎屑流的颗粒分析和建模；地热系统的地球化学分析；并检查火山活动和地表变形与区域构造之间的关系。 REU 学生将在实地考察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准备演示成果。 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（第一年和第三年）或 CSUSB（第二年）举行的年中会议以及全国会议。 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 进行招聘。 由于火山的多样性，可以直接研究各种过程和产品。因此，学生将获得广泛的研究经验，这些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显着提高对多米尼加火山灾害和复杂安山岩浆系统的了解。 多米尼加没有大学，该 REU 为灾害协调员办公室提供了宝贵的帮助。 此外，REU 将使美国本科生接触与他们自己的文化相似但仍显着不同的文化。鉴于目前对 Earthscope 的投资，火山系统中的 REU 是及时的。
