  • 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):

  • International Data Rescue Award in the Geosciences

    Apr 2013.  IEDA and Elsevier have launched the 2013 International Data Rescue Award in the Geosciences challenge. The award has been established to improve the preservation and access of research data in the Geosciences, particularly of dark data, and to share the varied ways that these data are being processed, stored, and used. The winner of the challenge will receive a $5000 prize at the American Geophysical Union meeting in December 2013.


    Members of the international geosciences community who have worked or are working on projects that have advanced preservation and access of research data are invited to submit a description of teir project to the challenge. Specifically, we are interested in receiving submissions from groups who have developed and completed projects which either:


    1. Digitized content that has formerly been available in only analog or obsolete elecronic formats, including the addition of rich metadata to make this content more easily accessible and re-usable.
    2. Developed data standards, tools, and processes that facilitate and improve the ingestion of research data with rich metadata into sustained, openly accesible community databases.


    See for full details, or contact the organizers:


    Submissions are due by October 13, 2013.
