  • 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.

  • New versions of PetDB and SedDB released

    Apr 2013.  EarthChem has released new versions of the PetDB and SedDB web applications, offering several improvements and new features. Visit the IEDA feedback page to submit your ideas for new features and improvements, browse other suggestions, and vote for ideas that you like! 


    PetDB version 2.5.0

    • Map search has a new click and draw interface.
    • The MGDS GMRT (Global multi-resolution topography map) is now the basemap for Sample Info, Station Info, and Result View map pages, providing more detail of sea floor topography.
    • The PetDB Reference page displays data entry status and comments.
    • Users may download an excel spreadsheet of a single reference showing all data entered for the reference. Once a Publication (Reference, Author) search is started and results are shown, the button is under "Download Reference -> Excel" in the "Select Reference" display.


    SedDB version 1.3.3
