REU Site: Dynamic Earth in the 21st Century: Undergraduate Research on the Evolution of Earth's Interior, Surface and Climate

21世纪的动态地球是美国国家科学基金会本科生研究经验（REU）网站，由布朗大学地球、环境和行星科学系（DEEPS）和领导力联盟合作运营。该项目的主要目标是让在科学领域处于历史边缘地位的本科生能够参与令人兴奋的、受到良好指导的暑期研究经历；发展关键研究和专业技能；并建立他们对研究过程、研究生院和研究职业的理解。每年的夏季，8名就读于布朗大学以外学校的本科生将来到布朗大学校园，在DEEPS教师的指导下进行为期9周的研究。REU学生将得到研究实验室团队的进一步支持，每周两次的队列讨论小组，以及领导力联盟的高效专业发展和网络项目，领导力联盟是一个全国性的联盟，致力于培训和指导来自不同文化和学术背景的学生，使他们能够参加有竞争力的研究生课程和专业研究为基础的职业。REU的学生将通过在领导联盟全国研讨会和布朗大学夏季研究研讨会上的演讲，提高他们以书面形式交流工作的能力。在接下来的一年里，REU的学生将有机会在一个符合他们兴趣的国家科学会议上展示他们的工作。REU学生的研究项目将涵盖一系列的研究主题，包括：1)用地震波测量地幔特性，并模拟地幔粘度如何影响冰盖融化对海平面变化的预测；2)评估俯冲带在水再循环到地幔中的作用；3)了解火山喷发和岩浆库稳定的过程，模拟地球和其他行星上火山大厦的形成；4)开发新的岩石热史测量工具；5)测量湖泊和海洋沉积物的过去气候变化记录，并评估沉积物变形结构的冰川再推进；(6)气候变化与植被的反馈模拟；7)以城市景观为重点，评估空气和水质的驱动因素。这些项目包括对社会相关主题的影响，如气候变化及其影响，包括海平面上升、野火和植被反应；空气和水质；还有火山爆发。招聘将重点关注历史上被边缘化群体的学生或在参与地球科学方面面临其他障碍的学生：来自STEM中代表性不足的种族和族裔群体的学生、女性和非二元学生、第一代大学生、来自低收入家庭的学生、就读于地球科学研究机会有限的学校的学生以及残疾学生。该项目欢迎所有性取向、性别认同和表达的学生，以及来自不同生活经历和学术道路的学生，包括退伍军人。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Dynamic Earth in the 21st Century is a National Science Foundation Research Experiences for Undergraduates (REU) Site that is collaboratively run by Brown University’s Department of Earth, Environmental and Planetary Sciences (DEEPS) and the Leadership Alliance. The primary goals are to enable undergraduates from groups historically marginalized in the sciences to engage in exciting, well-mentored summer research experiences; develop key research and professional skills; and build their understanding of the research process, graduate school and research careers. In each of three summers, eight undergraduates who attend schools other than Brown University will come to Brown’s campus for nine weeks of research, mentored by DEEPS faculty. REU students will be further supported by research lab teams, a twice-weekly cohort discussion group, and the highly effective professional development and networking programs of the Leadership Alliance, a national consortium dedicated to training and mentoring students from diverse cultural and academic backgrounds for competitive graduate programs and professional research-based careers. REU students will enhance their abilities to communicate their work in writing and through presentations at the Leadership Alliance National Symposium and a summer research symposium at Brown. In the following year, the REU students will have the opportunity to present their work at a national science meeting that aligns with their interests. REU student research projects will span a range of research themes, including: 1) Measuring mantle properties with earthquake waves, and modeling how mantle viscosity affects predictions of sea-level change in response to melting ice sheets; 2) Assessing the role of subduction zones in recycling water into Earth’s mantle; 3) Understanding the processes that contribute to volcanic eruptions and magma chamber stability, and modeling the formation of volcanic edifices on Earth and other planetary bodies; 4) Developing new tools to measure rock thermal histories; 5) Measuring the record of past climate change in lake and ocean sediments, and assessing glacial re-advances with sediment deformation structures; 6) Modeling the feedbacks between climate change and vegetation; 7) Assessing the drivers of air and water quality with a focus on urban landscapes. These projects include implications for societally-relevant topics such as climate change and its impacts including sea-level rise, wildfires, and vegetation responses; air and water quality; and volcanic eruptions. Recruitment will focus on students from historically marginalized groups or who face other barriers to participation in the geosciences: students from racial and ethnic groups underrepresented in STEM, women and non-binary students, first-generation college students, students from lower income households, students who attend schools where geoscience research opportunities are limited, and students with disabilities. The program welcomes students of all sexual orientations, gender identities and expressions, and students from diverse life experiences and academic paths, including veterans.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
