The "Critical Zone" of the Earth includes the portion of the planet from the atmosphere through groundwater. Important characteristics of the Critical Zone are buried within it: how does the ground beneath our feet vary, how has it developed over time, and, how can we predict changes that may occur across time and space. Addressing these questions will affect how we manage the projected increase in demand for food, energy, and water that will accompany the growth in human population to 9 billion people by 2050. This project is a Research Coordination Network (RCN) that will bring together scientific expertise and students to explore these topics.This research coordination network (RCN) is intended to synthesize data and models to investigate a key research question: How has the structure of the Critical Zone evolved in the past and how will it respond to future perturbations resulting from increasingly intensive human activities? Quantifying the depth of Critical-Zone processes is important because it connects multiple areas of investigation: water storage, weathering, biogeochemical fluxes, and societal needs. Coupling models to data is difficult, since different research domains define the Critical Zone by changes in conditions that are hard to reconcile. Quantifying the gradient in properties that may define the lower boundary of the Critical Zone requires an injection of new ideas, methods, and people from across disciplines. This RCN is built around the following four topics: 1) synthesis efforts that help guide the coming decade of research on Critical-Zone architecture; 2) exploration of a diverse set of complimentary approaches for identifying the lower boundary of the Critical Zone and its influence on processes; 3) training of scientists in multidisciplinary data collection and modeling approaches; and 4) pathways to develop the next generation of Critical-Zone models. This RCN will involve at least 100 scientists, including early-career faculty, postdoctoral associates, and graduate students. Participants will be recruited from underrepresented ethnic, socio-economic, ability, and sexual identity groups. In addition to large and small meetings of the participants, this RCN will offer workshops at annual meetings and through webinars that focus on networking, diversifying research skills, and proposal development that will benefit a wider cross-section of early-career professionals.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.

地球的“关键地带”包括地球从大气到地下水的部分。关键地带的重要特征隐藏在其中：我们脚下的土地是如何变化的，它是如何随着时间的推移而发展的，以及我们如何预测可能发生的时空变化。解决这些问题将影响到我们如何管理预计的粮食、能源和水需求的增长。到2050年，全球人口将增长到90亿。这个项目是一个研究协调网络（RCN），它将汇集科学专家和学生来探索这些主题。该研究协调网络（RCN）旨在综合数据和模型来研究一个关键的研究问题：关键带的结构在过去是如何演变的，以及它将如何应对未来日益密集的人类活动造成的扰动？量化临界区过程的深度很重要，因为它连接了多个调查领域：水储存、风化、生物地球化学通量和社会需求。将模型与数据耦合是困难的，因为不同的研究领域通过难以调和的条件变化来定义临界区域。量化可能定义临界区域下限的属性梯度需要注入新的想法、方法和来自不同学科的人员。该RCN围绕以下四个主题构建：1)有助于指导未来十年关键区域体系结构研究的综合努力；2)探索一套不同的互补方法，以确定临界区域的下边界及其对过程的影响；3)对科学家进行多学科数据收集和建模方法的培训；4)开发下一代临界区域模型的途径。该RCN将涉及至少100名科学家，包括早期职业教师、博士后助理和研究生。参与者将从代表性不足的种族、社会经济、能力和性别认同群体中招募。除了参与者的大大小小的会议之外，RCN还将在年会和网络研讨会上提供研讨会，重点关注网络、多样化的研究技能和提案开发，这将使更广泛的早期职业专业人士受益。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
