Collaborative Project: Facility Support: EarthChem - Advancing Data Management in Solid Earth Geochemistry

固体地球样品的地球化学数据为回答关于地球的基本问题提供了必要的信息，从它的成分变化到它的历史、结构和动力学。EarthChem项目（www.earthchem.org）旨在通过建立先进的地球化学数据管理系统，促进地球化学数据的编制、交流、服务和可视化，最大限度地利用固体地球化学数据在地球科学研究和教育中的应用。最终目标是让研究人员、教育工作者、学生和感兴趣的公众能够在更大的地球科学数据集的背景下单独探索地球化学数据。EarthChem基于并将扩展成功的地球化学在线数据库PetDB、NAVDAT和GEOROC的长期合作成果。为了实现其目标，EarthChem将开发一个“一站式地球化学数据商店”（EarthChem门户网站），具有跨联邦数据库的搜索功能，一个用户界面，提供简单直接的访问所有数据的能力，能够以标准化和集成的输出格式获得专门针对用户个人需求量身定制的数据集，以及用于数据质量评估、数据分析和可视化的通用工具。EarthChem的第二个重点是通过合并现有和未来数据来扩展数据存储量，以提供对最广泛和最丰富的数据集的访问和集成。策略包括通过在线互动工具促进用户和出版商提交数据，贡献重点项目，以及社区确定的关键数据集的输入。

EAR-0522222WalkerGeochemical data for solid earth samples provide essential information for answering fundamental questions about the Earth, from its compositional variation to its history, structure, and dynamics. The EarthChem project (www.earthchem.org) aims to maximize the application of solid earth geochemical data in Geoscience research and education by establishing an advanced data management system that will facilitate the compilation, communication, serving, and visualization of geochemical data. The ultimate goal is to allow researchers, educators, students, and the interested public to explore geochemical data alone and in the context of larger Earth Science datasets. EarthChem is based on and will expand the long-term collaborative effort of the successful geochemical online databases PetDB, NAVDAT, and GEOROC. In order to achieve its goals, EarthChem will develop a 'One-stop-shop for geochemical data' (EarthChem portal) with search capabilities across federated databases, a user interface that offers simple and straightforward access to all data holdings with the ability to obtain datasets specifically tailored to the user's individual needs in a standardized and integrated output format, and generally applicable tools for data quality assessment and data analysis and visualization. EarthChem's second focus is the expansion of data holdings through incorporation of both legacy and future data, to provide access to and integrate the widest and richest datasets possible. Strategies include the facilitation of data submission from users and publishers via online interactive tools, contribution of focused projects, and entry of critical datasets as identified by the community.
