Sample Identifiers and Metadata to Support Data Management and Reuse in Multidisciplinary Ecosystem Sciences
Guidance and tools for studies with a variety of biological and environmental samples.
Many Environmental System Science projects have complicated sample analysis workflows and need an efficient system for tracking samples as they are sent to different collaborators, labs, user facilities, and published online. Work to improve project sample tracking for multidisciplinary projects was driven by the user community of the US Department of Energy’s (DOE’s) data repository for Earth and environmental sciences—Environmental System Science Data Infrastructure for a Virtual Ecosystem (ESS-DIVE). We provide recommendations for assigning sample identifiers and associated metadata to describe a variety of sample types for multidisciplinary ecosystem science projects.
Persistent identifiers for samples, along with common metadata to describe a variety of biological and environmental sample types, provides essential information to improve the efficiency of sample tracking, and makes sample data more findable, accessible, interoperable, and reusable (FAIR).
Physical samples are foundational entities for research across biological, Earth, and environmental sciences. Data generated from sample-based analyses are not only the basis of individual studies, but can also be integrated with other data to answer new and broader-scale questions. Ecosystem studies increasingly rely on multidisciplinary team-science to study climate and environmental changes. While there are widely adopted conventions within certain domains to describe sample data, these have gaps when applied in a multidisciplinary context. In this study, we reviewed existing practices for identifying, characterizing, and linking related environmental samples. We then tested practicalities of assigning persistent identifiers to samples, with standardized metadata, in a pilot field test involving eight United States Department of Energy projects. Participants collected a variety of sample types, with analyses conducted across multiple facilities. We address terminology gaps for multidisciplinary research and make recommendations for assigning identifiers and metadata that supports sample tracking, integration, and reuse. Our goal is to provide a practical approach to sample management, geared towards ecosystem scientists who contribute and reuse sample data.
