Physical samples and the data generated by their study are fundamental to progress across many Earth science disciplines and, thus, should be FAIR (findable, accessible, interoperable, and reusable) to enable future scientific utility and transparency in research. The ability to find and re-use existing sample-based analyses is dependent both on the use of unique sample identifiers and on the quality and accessibility of sample documentation. The System for Earth Sample Registration (SESAR; www.geosamples.org) aids researchers and sample curators in making sample metadata FAIR, and in obtaining IGSNs (International Geo Sample Numbers) as globally unique and persistent identifiers that resolve to sample metadata. IGSNs are used to unambiguously refer to samples in the literature and in databases, allowing disparate analyses of samples to be discovered more readily and linked to each other. Data syntheses like EarthChem’s PetDB database, which has served as a pivotal source of geochemical data for more than 20 years, would simply not be possible without the use of unique identifiers and without access to key sample metadata. Further encouraging researchers to obtain and use IGSNs will increasingly enhance discovery of distinct, yet complementary, data produced on same or similar samples across an even broader range of resources. This presentation and demonstration will show how SESAR services currently support diverse workflows both for a broad range of researchers and sample types and what plans exist for the future. It will also demonstrate how SESAR supports sample-based data syntheses and repositories, especially those operated by EarthChem (www.earthchem.org).

物理样本及其研究产生的数据是众多地球科学学科进步的基础，因此，这些样本数据应遵循FAIR原则（可发现性、可访问性、互操作性及可重用性），以促进未来的科学效用和研究透明度。发现和重用现有基于样本的分析能力既取决于独特样本标识符的使用，也取决于样本文档的质量和可访问性。地球样本注册系统（SESAR；www.geosamples.org）协助研究人员和样本保管者使样本元数据符合FAIR原则，并获取IGSNs（国际地理样本编号）作为全球唯一且持久的标识符，这些标识符指向样本元数据。IGSNs用于在文献和数据库中明确指代样本，使得对样本的不同分析更容易被发现并相互关联。如地球化学的PetDB数据库这样的数据综合，作为超过20年地球化学数据的关键来源，若没有使用唯一标识符和访问关键样本元数据，其存在将不可想象。进一步鼓励研究人员获取和使用IGSNs将不断促进在更广泛的资源上发现独特且互补的数据。本次演示将展示SESAR服务如何目前支持多种工作流程，涵盖广泛的研究人员和样本类型，以及未来存在的计划。它还将演示SESAR如何支持基于样本的数据综合和存储库，特别是那些由地球化学（www.earthchem.org）运营的存储库。
