Collaborative Research: Elements: Linking geochemical proxy records to crustal stratigraphic context via community-interactive cyberinfrastructure

合作研究：要素：通过社区互动的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集成了两个数据系统，它们采用不同的方法以数字方式描述地球的地质历史。Macrostrat描述了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，记录了过去特定时间的普遍条件信息。将这两种理解“岩石记录”的方法统一起来，可以更准确地比较不同尺度和不同地质时间的地球化学替代记录所携带的特定地点和特定时间的信息(例如，水化学、温度、大气成分、营养水平)。Macrostrat和SGP的联合提高了两个数据系统的操作效率：Macrostrat提供了一个复杂的背景和年龄建模框架来围绕SGP地球化学数据，而SGP联盟则指导一个庞大而活跃的研究人员社区来扩展Macrostrat柱数据集。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有一种新的联合体结构，有效地参与了许多研究人员的努力，但它缺乏有效的年龄模型来对齐地质时代的测量结果。该项目通过1)将SGP样品与Macrostrat单位和柱联系起来，2)为地层柱可视化和输入建立新的网络界面，以及3)使SGP社区参与捕获与地球化学数据集相关的柱，从而将这些方法结合在一起。新的API数据访问终端和网站将提供对大量结构良好和协调一致的地层和地球化学数据的访问。一种新的列输入Web应用程序允许广泛参与地层数据的收集、管理和使用。背景记录一旦汇编，将支持整合大量和基于代理的岩石测量的新研究方法。这一奖项由NSF高级网络基础设施办公室获得，由研究、创新、协同和教育部门(RISE)、地球科学部门(EAR)以及NSF地球科学局内的沉积地质和古生物学项目联合支持。该奖项反映了NSF的法定使命，并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，被认为值得支持。

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.
