Data Submission Overview
The EarthChem Library (ECL) is a data repository that archives, publishes, and makes accessible data and other digital content from geochemical, geochronological, and petrological research, including analytical data, data syntheses, models, technical reports, and more.
Repository Services
Data Access & Discovery
Access to the EarthChem Library is open and free. Data submission and curation services are free to data submitters. Similarly, data can be accessed for free via the EarthChem Library Search Tool.
Circulation and/or publication of materials obtained from this site is must adhere to the licensing requirements as stipulated by the provider of the dataset(s).
Data Licensing

Data Registration with DOI
Datasets in the ECL can be identified, shared, published and cited by using a Digital Object Identifier (DOI). The EarthChem Library is part of IEDA, a publication agent with the DataCite consortium. Learn more about DOIs and how to cite EarthChem data.
Quality Control & Assurance
All datasets submitted to the ECL undergo metadata completeness and technical data review by domain-specific curators.
Release Date Management
Dataset files can have a public release date (embargo period) of up to two years in the future from the original submission date. The files can be updated during the embargo period while the DOI remains the same.
Long-Term Preservation
ECL guarantees long-term availability and preservation of its content through Amazon S3 Glacier Deep Archive and the Lamont-Doherty Earth Observatory.
Data Interoperability
ECL offers interoperability through external identifiers for related publications, NSF award numbers, IGSN, SESAR sample profiles, R2R cruise IDs, and GVP volcano numbers.
