Biosphere 2 Earth Systems Research for Environmental Solutions (B2-REU) gives students the opportunity to conduct interdisciplinary environmental and Earth systems science research and connect their work to existing environmental challenges and solutions, thereby increasing research relevance and student motivation. This 10-week summer REU site will foster the scientific career development of students coming from groups underrepresented in science, including minority and 1st generation students, and undergraduate students from universities with limited research opportunities. The B2 setting, along with nearby field sites and support laboratories, provides a unique environment to excite students about research and future careers in science, while the strong team of faculty mentors ensures that students are exposed to state-of-the-art research, learn current techniques, and create important connections in the scientific community. To complement the research, students participate in weekly research-seminar discussions with University of Arizona scientists; professional development activities, such as public speaking and graduate school workshops; and outreach training. Students learn to communicate their research to the thousands of B2 visitors. The summer culminates in a student undergraduate research symposium. Students are also supported to share with the scientific community by presenting at a professional meeting of their choice following the summer experience.Student projects take advantage of the B2 research infrastructure, allowing for a high degree of control at large scales, and the NSF Critical Zone Observatory (CZO) and other field sites in the Sonoran desert and sky-island mountains around Tucson to improve our understanding of Earth systems. Questions like how water moves through the critical zone, how ecosystems respond to environmental variation and anthropogenic change, and how physical and biological elements of systems are integrated are answered using knowledge from many disciplines, including hydrology, geology, geochemistry, ecology, biology, physics, engineering, and atmospheric sciences. Through active research, students learn first-hand how model and real world systems are used to generate scientific understanding. The program trains the next generation of scientists to tackle environmental issues with the necessary skills that bridge disciplines and with the ability to communicate research findings to the public and policy makers.

生物圈2地球系统的环境解决方案研究（B2-REU）使学生有机会进行跨学科的环境和地球系统科学研究，并将其工作与现有的环境挑战和解决方案联系起来，从而增加了研究的相关性和学生动机。这个为期10周的夏季REU网站将促进来自科学领域人数不足的学生的科学职业发展，包括少数民族和第一代学生，以及来自研究机会有限的大学的本科生。 B2环境以及附近的现场站点和支持实验室，为学生提供了一个独特的环境，以激发学生在科学领域的研究和未来职业，而强大的教职员工团队确保学生接触到最先进的研究，了解当前的技术，并在科学界建立重要的联系。为了补充这项研究，学生参加了与亚利桑那大学科学家的每周研究 - 阶段讨论；专业发展活动，例如公开演讲和研究生院研讨会；和外展培训。学生学会将他们的研究与成千上万的B2访客传达。夏季在学生本科研究研讨会上达到顶点。还支持学生通过在夏季体验后的专业会议上介绍科学界的分享。研究员的项目利用B2研究基础设施，可以在大规模的大规模控制和NSF关键区域进行高度控制。天文台（CZO）和图森附近的索诺兰沙漠和天空岛上的其他野外地点，以提高我们对地球系统的理解。诸如水如何穿越关键区域，生态系统如何响应环境变化和人为变化，以及使用许多学科的知识（包括水文，地质学，地球化学，生态学，生物学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，物理学，工程和大气科学。通过积极的研究，学生亲身学习如何使用模型和现实世界系统来产生科学理解。该计划训练下一代科学家，以弥合学科的必要技能以及将研究发现与公众和政策制定者传达的能力来解决环境问题。
