Collaborative Research: Elements: Linking geochemical proxy records to crustal stratigraphic context via community-interactive cyberinfrastructureThis project integrates two data systems which take different approaches to digitally describing the Earth’s geologic history. Macrostrat characterizes the bulk properties, spatial distribution, and age relationships of crustal rocks. The Sedimentary Geochemistry and Paleoenvironments (SGP) project compiles sample-derived proxy measurements that record information about the prevailing conditions at specific times in the past. Unifying these two approaches to understanding the “rock record” allows the site- and time-specific information carried by geochemical proxy records (e.g., water chemistry, temperature, atmospheric composition, nutrient levels) to be compared more precisely across scales and through geologic time. Aligning Macrostrat and SGP increases the operational effectiveness of both data systems: Macrostrat provides a sophisticated contextual and age modeling framework to surround SGP geochemical data, while the SGP consortium directs a large and active community of contributing researchers towards expanding the Macrostrat column dataset. These new capabilities support new science and provide geochemical data to the public.The reach and impact of Macrostrat’s advanced cyberinfrastructure for describing the Earth’s crust would be improved by integrating a wide collaborator base. SGP has a novel consortium structure that effectively engages the effort of many researchers, but it lacks an effective age model to align measurements in geologic time. This project combines these approaches by 1) linking SGP samples to Macrostrat units and columns, 2) building new web interfaces for stratigraphic column visualization and entry, and 3) engaging the SGP community in capturing columns that contextualize geochemical datasets. New API data access endpoints and websites will provide access to large volumes of well-structured and harmonized stratigraphic and geochemical data. A new column-entry web application allows broad participation in stratigraphic data collection, curation, and use. Contextual records, once compiled, will sustain new research approaches that integrate bulk and proxy-based rock measurements.This award by the NSF Office of Advanced Cyberinfrastructure is jointly supported by the Division of Research, Innovation, Synergies, and Education (RISE), the Division of Earth Sciences (EAR), and the Sedimentary Geology and Paleobiology Program within the NSF Directorate for Geosciences.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.

合作研究：要素：通过社区交互式集成网络基础设施将地球化学代理记录与地壳地层背景联系起来该项目设计了两个数据系统，它们采用不同的方法来数字化描述地球的地质历史，宏观地层描述了地壳岩石的整体特性、空间分布和年龄关系。沉积地球化学和古环境（SGP）项目编译了样本衍生的代理测量值，记录了过去特定时间的普遍条件的信息。统一这两种理解“岩石记录”的方法可以使地球化学代理记录（例如水化学、温度、大气成分、营养水平）所携带的特定地点和特定时间的信息在不同尺度和地质时间之间进行更精确的比较Macrostrat 和 SGP 的协调提高了两个数据系统的运行效率：Macrostrat 提供了一个复杂的上下文和年龄建模框架来围绕 SGP 地球化学数据，而 SGP 联盟则指导一个由贡献研究人员组成的大型活跃社区，以扩大Macrostrat 列数据集。这些新功能支持新科学并向公众提供地球化学数据。通过整合广泛的合作者基础，Macrostrat 用于描述地壳的先进网络基础设施的范围和影响将得到改善，该基础设施具有有效参与的新颖联盟结构。许多研究人员的努力，但缺乏有效的年龄模型来调整地质年代的测量结果，该项目通过 1) 将 SGP 样本与 Macrostrat 单元和柱相联系，2) 构建新的方法来结合这些方法。用于地层柱可视化和输入的 Web 界面，以及 3) 让 SGP 社区参与捕获与地球化学数据集相关的柱，新的 API 数据访问端点和网站将提供对大量结构良好且统一的地层和地球化学数据的访问。列式网络应用程序允许广泛参与地层数据收集、整理和使用。背景记录一旦编译，将支持基于批量和代理的岩石测量的新研究方法。该奖项由 NSF 高级办公室授予。网络基础设施由 NSF 地球科学理事会的研究、创新、协同和教育部 (RISE)、地球科学部 (EAR) 以及沉积地质学和古生物学项目联合支持。该奖项反映了 NSF 的法定使命和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，该项目被认为值得支持。
