  • PetDB reaches 500 citations in the published literature

    Jun 2014. Today, June 9, 2014, we have reached the 500th citation of the PetDB database! Since its inception in 2001, PetDB data has been cited 500 times in the published and peer-reviewed scientific literature.

    Use of PetDB data ranges from decoding subduction processes, to understanding volatile fluxes, to modeling of the Earth's core, proving the value of highly accessible, well-integrated data sets to the research community.


    The 500th citation is:


    Mohammad Ishaq Kakar, Andrew C. Kerr, Khalid Mahmood, Alan S. Collins, Mehrab Khan, Iain McDonald, 2014, Supra-subduction zone tectonic setting of the Muslim Bagh Ophiolite, northwestern Pakistan: Insights from geochemistry and petrology, Lithos,



  • Help EarthChem Help You: Take our short survey

    May 2014. For its 2014 NSF Review, IEDA:EarthChem is preparing a summary of its first four years and a plan for the future. Help us by filling out a short (less than 5 minute) survey on your experiences with IEDA and your opinion on future developments. Your opinion is very important to us!


    Take the 2014 IEDA Survey


    More info: In 2014 the NSF will review IEDA's services to the community and evaluate progress toward IEDA's strategic goals to determine its future path. Please help IEDA gather user feedback for this review by filling out the survey regarding your use of IEDA data collections and services in both your research and education activities. We encourage you to complete as much of the survey as you can and please remember to click "Submit" when you are finished. Send questions or comments to

  • New Data Template Allows Submission of Ar-Ar Geochronology Data

    May 2014. In addition to several other geochemistry and geochronology data templates, EarthChem now provides a new template for Ar-Ar geochronology. This new data template, along with the other geochronology templates, provides an easy and organized way for scientists to store and submit data to Geochron.


    Access the new Ar-Ar geochronology template as well as other geochemistry and geochronology on the EarthChem Data Templates Webpage. Please send your comments, questions, or suggestions to

  • EarthChem Invites Applications for IEDA Data Rescue Mini-Awards

    Apr 2014. EarthChem is looking to fund 3-4 Data Rescue Mini-awards as part of the IEDA Data Rescue Initiative. This initiative is intended to ensure that valuable legacy data sets that are in danger of being lost in the near future due to impending retirement or degradation of the original data source are preserved and made accessible to the community for re-use by inclusion in IEDA data collections such as the EarthChem Library and PetDB.


    Priority will be given to datasets that are deemed to have the highest impact on future research by virtue of one or another unique characteristics such as quality, size, rarity, unique location or data type, The mini-grants will provide funds to investigators at the level of $7,000 (maximum) for each project to support proper compilation, documentation, and transfer of data sets to IEDA. We specifically encourage applications from late-career and near-retirement investigators, who are in possession of unpublished data that they cannot otherwise share and preserve.


    Data sets must be consistent with the IEDA mission “to support access and preservation of solid earth data from the earth, ocean, and polar sciences”. Preferred data sets are in the subject areas of petrology and high-temperature geochemistry of igneous and metamorphic rocks (including mantle samples), mineral physics, and volcanology. Examples of past awards can be found at


    Applications should be submitted by May 30, 2014, to EarthChem (, and should include

    • brief description of the data sets that will be assembled, such as type of data, volume, format (.xls, .txt, etc.), and current status (e.g. on paper, on-line, etc.);
    • statement that explains the relevance of the data set(s) for future re-use (maximum 2 pages);
    • project plan how the successful completion of the project will be achieved and to what extent IEDA staff is needed to assist. For sample-based data such as geochemical analyses, the sample archiving situation should be discussed.
    • budget outline

    The IEDA User Committee will review all applications and select awardees based on the scientific relevance of the data sets and prospect of the project’s successful completion. Funded projects will need to complete the data compilation and documentation by December 31, 2014. IEDA staff will work with each awarded investigator or group of investigators to help identify needed documentation, and will provide guidance and tools to facilitate data documentation and transfer.
