Carbon occurs in many different chemical phases on Earth. As with elements in general, carbon is converted from one phase to another as part of a geochemical cycle. Importantly, carbon may be incorporated into greenhouse gases in the atmosphere and fossil fuels (among other phases), providing both societal and economic motivation to understand its chemical behavior. This project incorporates research and educational activities to promote a better understanding of how carbon is converted into different materials as part of the natural carbon cycle through geochemical data collection in the field, laboratory and classroom. Project participants will include students at the high school, community college and university levels, many of whom come from underrepresented groups in the sciences. Characterization of the carbon cycle requires an understanding of how phases are converted across Earth’s atmosphere, biosphere, hydrosphere and geosphere. This can be achieved through carbon concentration and stable isotope composition geochemical analyses. This project will explore many aspects of the carbon cycle related to greenhouse gas production, microbe-induced mineral formation, biologically critical intervals in Earth’s history and wildfire ash formation, among others. Recent technological advances have led to the development of relatively inexpensive and broadly accessible instrumentation (Cavity Ringdown Spectrometers) that can be used by not only experienced analytical scientists but also by more novice groups (e.g., high school students). This research and the involvement of individuals of variable technical skill level and academic knowledge will promote a far-reaching educational experience to educate next-generation scientists and scholar citizens.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.

碳存在于地球上许多不同的化学状态中。与一般元素一样，碳作为地球化学循环的一部分从一个阶段转化为另一个阶段。重要的是，碳可能会被纳入大气中的温室气体和化石燃料（以及其他阶段），为了解其化学行为提供社会和经济动力。该项目结合了研究和教育活动，通过在实地、实验室和教室收集地球化学数据，促进更好地了解碳是如何转化为不同材料的，这是自然碳循环的一部分。项目参与者将包括高中、社区学院和大学的学生，其中许多人来自科学领域代表性不足的群体。 碳循环的表征需要了解地球大气圈、生物圈、水圈和地圈中的阶段是如何转换的。这可以通过碳浓度和稳定同位素组成地球化学分析来实现。该项目将探索与温室气体产生、微生物诱导的矿物形成、地球历史上的生物关键间隔和野火灰烬形成等有关的碳循环的许多方面。最近的技术进步导致了相对便宜和广泛使用的仪器（腔衰荡光谱仪）的发展，其不仅可以由有经验的分析科学家使用，而且可以由更多的新手群体使用（例如，高中生）。这项研究以及不同技术技能水平和学术知识的个人的参与将促进深远的教育经验，以教育下一代科学家和学者公民。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
