  • Release of EarthChem Library v3.2

    Jul 2015. Publish your data and files in the new version of the EarthChem Library, v3.2, with new features for submission and search.

     

    • Ability to save a submission session if incomplete, so that you can finish and submit at a later time.
    • Search by IGSN (International GeoSample Number), so that you can find all ECL submissions that mention a specific sample.
    • Improved search for author/person, so that combinations of first and last names return expected results.

  • Release of PetDB v.2.8.6

    Jun 2015. PetDB v.2.8.6 is released, including several new features and bug fixes, including an improved sample search that includes options for "equals," "begins with," and "ends with" instead of just "includes."

     

    Other improvements include 

    • Sample information page URL now uses the sample_id as opposed to the internal database sample_num.
    • Enhanced Search statistics for internal use and development.
    • Improved book reference citation display.
    • Improved page number display for references.
    • Bug fix to avoid duplicated inclusion data in the table information view.

  • EarthChem Library datasets now linked from Science Direct

    Apr 2015. Datasets published with DOIs in the EarthChem Library can now be accessed from related articles in ScienceDirect. EarthChem banners are shown on ScienceDirect when EarthChem has data for the article. Previously, sample-based geochemical data from the EarthChem Portal were displayed. Now, a summary and link to EarthChem Library dataset profiles are also linked.

     

    If you are an author contributing to the EarthChem Library, make sure to specify the related dataset DOI in your Elsevier manuscript.

     

    Example article: Pb and Hf isotope variations along the Southeast Indian Ridge and the dynamic distribution of MORB source domains in the upper mantle, Hanan et al., 2013.

  • New Aleutian Arc datasets in PetDB

    Mar 2015. Guided by a group of Aleutian Arc investigators, high-profile geochemical analytical data sets were identified to aid the research community working in this area in data synthesis and interpretation. Over 9,000 geochemical data points from 50 references spanning the years 1961-2010 have been added to PetDB, including 2,400 mineral and over 1,000 melt inclusion analyses. Figure 1 shows the location of samples for which there are data available in PetDB. Figure 2, which depicts 144Nd/143Nd values across the arc, provides an example of the data probing that is now possible because of the recent data additions. To access the data, search PetDB by “Feature Name>Volcanic Arc>Aleutian/Kamchatka/Kuril-Kamchatka.”
