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地球系统环境解决方案研究(B2-REU)为学生提供了进行跨学科环境和地球系统科学研究的机会，并将他们的工作与现有的环境挑战和解决方案联系起来，从而增加研究的相关性和学生的积极性。这个为期10周的夏季REU网站将促进来自科学界代表性不足的群体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的环境，以及附近的现场站点和支持实验室，提供了一个独特的环境，让学生对科学研究和未来的职业生涯感到兴奋，同时强大的教师导师团队确保学生接触到最先进的研究，学习最新的技术，并在科学界建立重要的联系。为了补充这项研究，学生们每周都会参加与亚利桑那大学科学家的研究研讨会讨论；专业发展活动，如公开演讲和研究生院研讨会；以及外展培训。学生们学习如何与成千上万的B2访问者交流他们的研究成果。暑假的高潮是一场本科生研究研讨会。学生们还可以通过在暑期体验后选择的专业会议上发表演讲来与科学界分享。学生项目利用B2研究基础设施，允许在大范围内进行高度控制，以及NSF临界区天文台(CZO)和索诺兰沙漠和图森周围天空-岛屿山脉的其他野外地点，以提高我们对地球系统的理解。水如何通过临界区，生态系统如何对环境变化和人为变化做出反应，以及系统的物理和生物元素如何整合等问题，都是利用包括水文学、地质学、地球化学、生态学、生物学、物理学、工程学和大气科学在内的许多学科的知识来回答的。通过积极的研究，学生们第一手学习如何使用模型和现实世界系统来产生科学理解。该项目培训下一代科学家，以解决环境问题，拥有连接各学科的必要技能，以及向公众和政策制定者传达研究成果的能力。
