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站点包括西印度群岛多米尼加岛（4周）的现场工作，以及在阿肯色大学（UA）或加利福尼亚州立大学（CSUSB）的加利福尼亚州立大学（UA）或加利福尼亚州立大学（CSUSB）进行了4周的相关现场研究。一半的学生将在UA进行现场工作，在CSUSB进行一半。这些技术是田间火山学，全球定位系统（GPS）测量，简单的定量建模和实验室研究，包括岩石学和地热场所的岩化，沉积物和水域的地球化学。这些目标是在对岩浆系统，火山监测和危害评估感兴趣的本科生中发展研究，科学和技术技能。学生将与现场研究的合作伙伴配对，并在现场工作后4周开发单个项目进行其他研究。研究项目包括：使用GPS GEODESY来限制表面变形；识别单个火山的特征行为；火山碎屑流的颗粒分析和建模；地热系统的地球化学分析；以及对火山和表面变形与区域构造学之间的关系的检查。 REU学生将在野外季节结束时向当地岛上的观众和多米尼加灾难协调员的办公室准备演讲。 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（1和3年级）或CSUSB（2年级）和全国会议上举行的年中会议。 在身体科学专业的大三学生和高年级学生将在全国范围内以重点招募在他的和HBCU的招聘中，我们可以在这里进行个人接触。 由于火山学的多样性，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，这些研究经验可能应用于全球其他火山系统。 在三年期间，综合结果将显着提高多米尼加火山危害和一般复杂的安第斯山脉岩浆系统的了解。 多米尼加没有大学，而REU为灾难协调员办公室提供了宝贵的援助。 此外，REU将使美国的大学生接触类似于自己的文化，但仍然有很大不同。鉴于当前在Earthscope上的投资，火山系统中的REU是及时的。
