项目摘要

Soils contain a large amount of the Earth's carbon. The rate at which this carbon gets released as carbon dioxide (CO2) depends on a number of factors, including changes in soil microbial activity and environmental characteristics. Measuring the rates of CO2 emission from the soil to the atmosphere is an essential component needed to model and understand global environmental change. The NSF-supported National Ecological Observatory Network (NEON) makes continuous measurements of all the required components to determine soil carbon flux (the balance between the rate of carbon buildup vs. discharge as CO2) at a given site. The researchers in this project will compute soil flux at each of the twenty core NEON sites across the continental U.S. and cross-reference them with other existing databases. The researchers will also recruit five faculty at primarily undergraduate institutions (PUIs) for a faculty training cohort in a suite of instruction, peer mentorship, and educator development activities. This cohort will result in greater engagement of faculty and undergraduate students with existing NEON data and ecology research. In collaboration with the recruited faculty, the researchers will develop a series of education modules in biology that is estimated to impact several hundred undergraduate students annually. The faculty cohort will also engage in professional development focused on broadening participation among diverse undergraduate students and researchers.NEON infrastructure includes soil sensor arrays that record all the necessary components for calculating continuous soil CO2 flux. The delivery of computed soil CO2 flux values as a higher-level data product is a widely-sought application of NEON data. This project will fill this data gap by developing and field-validating a freely available R package to easily and rapidly calculate soil CO2 flux at any core terrestrial NEON site. The researchers will validate the results through direct measurements, ground-truthing the measurements against existing soil respiration databases, and apply the soil flux data product in modeling and data assimilation to parameterize soil biogeochemical models at a focal core NEON site. During the third year of this project, the researchers will recruit five faculty from primarily undergraduate institutions (PUIs) to engage in a faculty mentoring cohort. Participating faculty will: (1) join together in a mentoring cohort to refine and pilot education modules in macrosystems environmental science for undergraduate students, thus building networks of practice in the teaching of macrosystems ecology; (2) contribute to the validation of the soil CO2 flux data product, thus building their technical skills in instrumentation, data analysis, and facility with NEON sites and data products; and (3) develop their intercultural competency skills, increasing their ability to mentor undergraduate researchers from underrepresented backgrounds, thus working towards diversifying environmental science and its STEM workforce.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.
土壤含有大量地球碳。这种碳以二氧化碳 (CO2) 的形式释放的速率取决于许多因素,包括土壤微生物活动和环境特征的变化。 测量从土壤到大气的二氧化碳排放率是建模和了解全球环境变化所需的重要组成部分。 NSF 支持的国家生态观测站网络 (NEON) 对所有必需的组件进行连续测量,以确定给定地点的土壤碳通量(碳积累速率与二氧化碳排放速率之间的平衡)。该项目的研究人员将计算美国大陆 20 个核心 NEON 站点中每个站点的土壤通量,并将其与其他现有数据库进行交叉引用。 研究人员还将在主要本科院校(PUI)招募五名教职人员,进行一系列教学、同伴指导和教育者发展活动的教职人员培训。 该群体将导致教师和本科生更多地参与现有的 NEON 数据和生态学研究。 研究人员将与招募的教师合作开发一系列生物学教育模块,预计每年影响数百名本科生。 教师队伍还将致力于专业发展,重点是扩大不同本科生和研究人员的参与。NEON 基础设施包括土壤传感器阵列,可记录计算连续土壤二氧化碳通量的所有必要组件。将计算出的土壤二氧化碳通量值作为高级数据产品提供是 NEON 数据的广泛应用。该项目将通过开发和现场验证免费提供的 R 包来填补这一数据空白,以轻松快速地计算任何核心陆地 NEON 站点的土壤二氧化碳通量。 研究人员将通过直接测量来验证结果,根据现有土壤呼吸数据库对测量结果进行地面验证,并将土壤通量数据产品应用于建模和数据同化,以参数化焦点核心 NEON 站点的土壤生物地球化学模型。在该项目的第三年,研究人员将从主要本科院校(PUI)招募五名教师来参与教师指导队伍。参与教师将:(1)联合导师团队,完善和试点本科生宏观系统环境科学教育模块,从而建立宏观系统生态学教学的实践网络; (2) 有助于土壤二氧化碳通量数据产品的验证,从而培养他们在仪器、数据分析以及 NEON 站点和数据产品设施方面的技术技能; (3) 培养他们的跨文化能力技能,提高他们指导来自代表性不足的背景的本科研究人员的能力,从而努力实现环境科学及其 STEM 劳动力的多元化。该奖项反映了 NSF 的法定使命,并通过使用基金会的评估进行评估,认为值得支持。智力价值和更广泛的影响审查标准。
