IEDA EarthChem: Geochemical Sample Measurements and Synthesis Databases

EarthChem, part of the Integrated Earth Data Applications (IEDA), develops and maintains a suite of data systems to support the geochemistry community. The systems include the EarthChem Library for dataset publication, topical synthesis databases like PetDB and SedDB, and the EarthChem Portal for discovery and analysis. Contributing authors receive citable DOIs, and the community benefits from open access to integrated geochemical data.

Use Cases

• Integrating geochemical measurements from diverse sample types and analytical procedures as described.
• Discovering and accessing published geochemical datasets via the EarthChem Library and Portal.
• Conducting meta-analyses using integrated data from synthesis databases like PetDB and SedDB.
• Tracking data usage and impact through citable DOIs and usage reports provided to authors.

Strengths

• Data is integrated from multiple sources into synthesis databases, facilitating cross-study analysis.
• Authors receive citable DOIs and usage reports, which may incentivize data sharing.
• The system is described as supporting open access, leading to accelerated scientific discovery.

Limitations

• Row count, column definitions, and file formats are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• Column-level documentation is absent; field semantics must be inferred after download.
