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.

碳发生在地球上许多不同的化学阶段。与一般的元素一样，作为地球化学循环的一部分，碳从一个相转换为另一个相。重要的是，碳可以将碳和化石燃料（除其他阶段）中纳入温室气体中，从而提供了社会和经济动机，以了解其化学行为。该项目结合了研究和教育活动，以更好地了解碳如何通过现场，实验室和课堂收集的地球化学数据收集自然碳循环的一部分转化为不同的材料。项目参与者将包括高中，社区学院和大学级别的学生，其中许多来自科学中代表性不足的小组。碳循环的表征需要了解如何在地球大气层，生物圈，水圈和地质圈中转化的相位。这可以通过碳浓度和稳定的同位素组成地球化学分析来实现。该项目将探讨与温室气体产量，微生物诱导的矿物质生产，地球历史上的生物学关键间隔以及野火灰分形成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且广泛可访问的仪器（腔度响应光谱仪）的发展，这些仪器不仅可以被经验丰富的分析科学家，而且可以被更多喷嘴组（例如高中生）使用。这项研究以及可变技术技能水平和学术知识的个人的参与将促进教育的下一代科学家和学者公民的深远教育经验。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估来评估的。
