This is the test page for the Editor's Roundtable - an Initiative for Best Practices for Data Publication
What is the Editor's Roundtable?
The Editor's Roundtable is a community-based initiative, conceived by editors, publishers, and operators of data facilities at a series of meetings held in conjunction with major scientific conferences that IEDA facilitated. It is an effort to facilitate and foster communication and knowledge exchange among editors and publishers of Earth Science journals and Earth Science data facilities with the goal to develop, implement, and promote guidelines and best practices for scholarly publishing with particular emphasis on the publication of data in support of open access policies.
The Editors Roundtable builds on a successful initiative started in 2007 by EarthChem, which since 2010 is part of the IEDA data facility, to develop and promote best practices for the reporting of geochemical data in scholarly articles and data systems, and that resulted in a Policy Recommendation Requirements for the Publication of Geochemical Data (Goldstein et al. 2014, doi:10.1594/IEDA/100426), which was endorsed by all major scientific journals that publish geochemical data and has guided policies for the disclosure and documentation of geochemical data.
The “best practices” will include standards for:
- Archiving and curating data sets;
- Setting references and identifiers;
- Linking datasets to publications;
- Integrating with emerging data citation practices and bibliometrics for data;
- Complying with interoperability standards.
- Data Accessibility and Format
Access to the complete data, upon which new scientific discovery and knowledge is based, is a fundamental requirement for the reproducibility of scientific results. All NEW geochemical data used in a publication must be made available for future use by (1) submission to an accessible, persistent source such as a public database or data archive (for example, personal web sites are not persistent data archives), if it exists for the specific data type, or by (2) listing the data explicitly in a data table associated with the publication. The data must in any case be available in downloadable format. For chemical abundance data of samples, elemental or oxide abundance data must be given unless a compelling reason can be provided; elemental abundance ratios are acceptable only if the compositional data do not exist. Isotope ratios are, of course, acceptable.
Data should be reported in tabular format. Data must always be available as a downloadable file in a format that can be easily converted into spreadsheet format (for example, .csv, .txt). The file should include units for the listed measured values. This means that if a publication contains a data table in the main text or a pdf or image version of the data table as an electronic supplement, the data in the table(s) must also be available in a downloadable form that can be easily converted to spreadsheet format.

- Data Quality Information
Proper documentation of data quality is fundamental for comparison of research results and estimation of uncertainty. Authors must provide sufficient information (metadata) about the analytical process and reproducibility of measurements in order that the data quality can be properly evaluated. Correction procedures need to be clearly presented. This information is necessary to allow for scholarly reproduction of the results. Basic metadata such as analytical technique, lab, and values measured on reference materials need to accompany the data. If possible, metadata should be provided in standardized tabular format to facilitate access to this information for editors, reviewers, readers, and data managers. Information about the analytical procedure must be provided for each measured parameter. If a parameter has been analyzed by more than one method, each method must be documented separately. If possible, this information should be provided in tabular format. 1. GENERAL ANALYTICAL METADATA must include: a. Analytical technique (e.g. ICP, XRF, EMP) b. Laboratory (name of department/lab & institution) c. Analytical accuracy & reproducibility i. Name(s) and measured value(s) of (internationally recognized) reference standard(s) measured as unknown sample ii. Estimated uncertainty of reference standard measurement, and, if applicable, number of measurements 2. METHOD SPECIFIC METADATA must include, as appropriate to the method (see Appendix): a. Fractionation correction b. Standardization (Normalization) c. Total procedural blank d. Detection limit e. Calibration Method Specific Analytical Metadata The list below identifies metadata sets that are relevant for different types of analytical techniques, which may vary depending upon the specific analysis: A. Bulk Elemental Analyses (e.g. AAS, HPLC, ICPAES, ICPMS, INAA, XRF) a. Standardization (Normalization) b. Total procedural blank c. Detection limit B. In-situ Elemental Analyses (e.g. EMP, SIMS, LA-ICPMS) a. Standardization (Normalization) b. Detection limit c. Calibration C. Bulk Isotopic Analyses (e.g. TIMS, MC-ICPMS) a. Standardization (Normalization) b. Fractionation correction c. Total procedural blank d. Detection limit D. In-situ Isotope Analyses (e.g. SIMS, LA-MC-ICPMS, LA-ICPMS) a. Standardization (Normalization) b. Detection limit c. Normalization d. Fractionation correction
- Sample Information
The geochemical data addressed in this policy are tied to samples. Essential information about the samples must be provided in order to allow for proper identification of their origin and type, and to trace their analytical history. All natural samples for which data are reported require, if applicable, information about the sample location. In addition and if applicable, samples should be classified (e.g. lithology for rocks and sediments, species for minerals and fossils). Samples should have global unique identifiers so that data can be unambiguously referenced to a sample. This allows a complete analytical profile of a sample to be established that includes data generated at different times or in different labs, and reported in different publications.
a. Metadata: All samples for which data are reported require, if applicable, information about sample location including, if possible latitude and longitude (if these are unknown, approximate coordinates obtained by using Google Earth would suffice). Marine samples require a depth below sea level. If applicable, the position of a sample within a stratigraphic section or within a core should be reported. Other critical sample metadata include lithological classification and age. b. Unique Identification: The problem of non-unique sample names needs to be addressed by the global earth science community. Currently, the only available system where individuals can obtain global unique identifiers for their samples is the sample registry SESAR (System for Earth Sample Registration, www.geosamples.org). The unique identifier provided and administered by SESAR is the 9-digit alphanumeric International Geo Sample Number (IGSN), which is used together with a person’s or institution’s sample name to ensure unambiguous identification of a sample. IGSNs can be obtained from SESAR by submitting the information about a sample that is required for publication through this policy.
Sample Metadata The list below identifies which metadata should be provided for samples (if applicable). a. Sample name b. Geospatial coordinates (latitude, longitude, possibly even utilizing Google Earth for an approximate value if otherwise unknown) c. Unique Identifier (e.g. International GeoSample Number, IGSN) d. Classification (e.g. lithology) e. Age f. Depth in core or position within a stratigraphic section (if applicable)
g. Cruise or field program (if applicable)
Recommended practices for citations
The core required elements of a citation are Author(s)--the people or organizations responsible for the intellectual work to develop the data set. The data creators. Release Date--when the particular version of the data set was first made available for use (and potential citation) by others. Title--the formal title of the data set Version--the precise version of the data used. Careful version tracking is critical to accurate citation. Archive and/or Distributor--the organization distributing or caring for the data, ideally over the long term. Locator/Identifier--this could be a URL but ideally it should be a persistent service, such as a DOI, Handle or ARK, that resolves to the current location of the data in question. Access Date and Time--because data can be dynamic and changeable in ways that are not always reflected in release dates and versions, it is important to indicate when on-line data were accessed. Additional fields can be added as necessary to credit other people and institutions, etc. Additionally, it is important to provide a scheme for users to indicate the precise subset of data that were used. This could be the temporal and spatial range of the data, the types of files used, a specific query id, or other ways of describing how the data were subsetted. An example citation: Cline, D., R.
