  • Editors Roundtable at Goldschmidt 2013

    The Editors Roundtable that was established during the Goldschmidt Conference 2007 to develop recommendations for best practices in geochemical data publication will re-convene for the first time since 2008 at the upcoming Goldschmidt Conference 2013.


    The Editors’ Roundtable released a Policy Statement in January 2009 regarding ‘Requirements for the Publication of Geochemical Data’ to guide editorial policies and recommend best practices. Since 2009, many developments in public policies, digital publication capabilities, and scientific data infrastructure have impacted and substantially augmented the relevance of access and management of research data. It is therefore timely to take advantage of the upcoming Goldschmidt Conference and re-assemble the Editors Roundtable to assess the status of data publication practices and data access in geochemistry, and review and eventually revise the Editors Roundtable Policy Statement in the light of the new data landscape.


    If you are an editor or publisher and interested to join the Editors Roundtable, please contact

  • EarthChem Town Hall at Goldschmidt 2013 in Florence, Italy

    Please join us at the EarthChem Town Hall at the upcoming Goldschmidt Conference 2013!


    When: Monday, August 26, 2013, 12:30PM

    Where: Room L08 of the conference venue



    We will provide updates on recent developments in data publication and digital management of geochemical data and samples., including reports on recent workshops that have focused on the development of cyberinfrastructure, and other related initiatives. Topics will include:


    • Publication and Citation of data and samples; Editors Roundtable in Geochemistry
    • IEDA’s Data Rescue Initiative
    • Report on EarthCube workshop ‘Developing a Cyberinfrastructure Vision for Geochemistry & Petrology’
    • Report on workshop ‘Geomaterials Genome project’ (M. Ghiorso)

  • Release of PetDB v.2.6.1

    Jul 2013. Check out the new version of PetDB, v.2.6.1, with new features and bug fixes that allow new feedback mechanisms and easier ways to download and view relevant data and metadata.

    • New feedback buttons on the data download page: Have you ever reached the data download page and realized you had a comment or question about data from a specific reference? Click on the new feedback icons in the data download table to send an email directly to the PetDB managers. 
    • Tag-along data downloads allow you to add on additional data types, such as majors, traces, or isotope ratios, to your initial query for samples. This allows users to preserve their sample selection and download additional data, for those situations where repeating the query with new additional new data types would change the sample selection.
    • New Analysis Comment display for all data types displays more analysis metadata to the user.
    • New layout and style for the "Select Reference List Data" page when searching by Reference
    • Notification of "In Progress" papers on the Reference page
    • The Excel download option for PetDB References has been moved out of the public interface while improvements are being made. Email if you have questions about this.
    • Bug fix so that negative numbers can be entered into the map search boxes on the Chrome and IE browsers.

    Let us know what you think about the new version by emailing, or by clicking the orange feedback button on the right-hand side of the webpage.


  • Geochron Data Submission Levels and User Control on Data Access and Modification

    Jul 2013. Building on our experience from the IEDA and EarthChem, the Geochron database has three levels of data storage and access: private, public, and published. The submitter controls private data. These data can only be seen by the submitter or a submitter-defined group of users. Public data are discoverable by anyone visiting the site, but can be changed by the submitter at any time. Published datasets cannot be changed, and will be archived at the gold-standard archive at the IEDA EarthChem Library and given a DOI. This arrangement will completely satisfy the NSF data reporting criteria.


    Publication of Geochron data is done by the user defining a dataset consisting of numerous samples. This is then published to the EarthChem library directly and seamlessly from the Geochron site. Once published, the dataset is given a unique identifier at Geochron. An example of this is from the recent paper by Blackburn and others (Zircon U-Pb Geochronology Links the End-Triassic Extinction with the Central Atlantic Magmatic Province published in Science, May 2013):
