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：通过社区互动网络基础设施将地球化学代用记录与地壳地层背景联系起来该项目整合了两个数据系统，这两个系统采用不同的方法以数字方式描述地球的地质历史。宏观地层表征地壳岩石的整体性质、空间分布和年龄关系。沉积地球化学和古环境（SGP）项目汇编了样品衍生的替代测量结果，记录了过去特定时间的主要条件信息。统一这两种理解“岩石记录”的方法，可以使地球化学代用记录（例如，水化学、温度、大气成分、营养水平）进行更精确的跨尺度和跨地质时代的比较。Macrostrat和SGP的结合提高了两个数据系统的运营效率：Macrostrat提供了一个复杂的上下文和年龄建模框架，以围绕SGP地球化学数据，而SGP联盟指导了一个庞大而活跃的贡献研究人员社区，以扩大Macrostrat列数据集。这些新的能力支持新的科学，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覆盖范围和影响将得到改善。SGP有一个新颖的联盟结构，有效地吸引了许多研究人员的努力，但它缺乏一个有效的年龄模型来调整地质年代的测量。该项目通过以下方式结合了这些方法：1）将SGP样本链接到Macrostrat单元和柱，2）构建用于地层柱可视化和输入的新网络界面，以及3）让SGP社区参与捕获将地球化学数据集背景化的柱。新的API数据访问端点和网站将提供对大量结构良好和统一的地层和地球化学数据的访问。一个新的列输入网络应用程序允许广泛参与地层数据的收集，管理和使用。背景记录，一旦编译，将维持新的研究方法，集成批量和代理为基础的岩石测量。这个奖项由NSF高级网络基础设施办公室联合支持的研究，创新，协同和教育（RISE），地球科学（ESTA），以及NSF地球科学理事会的沉积地质学和古生物学计划。该奖项反映了NSF的法定使命，并被认为值得通过以下方式获得支持：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。
