IEDA Community

  • IEDA Repositories EarthChem and Marine Geoscience Data System are recommended by Nature's Scientific Data Journal. Scientific Data offers a new article type, the ‘Data Descriptor’, which has been specifically designed to publish peer-reviewed research data in an accessible way, so as to facilitate its interpretation and reuse. Read more. 
  • IEDA EarthChem will be at the Goldschmidt Conference in Prague this month, running a full-day workshop with international participants: "EarthChem User Forum for the Publication, Discovery, Access, and Rescue of Geochemical, Petrological and Mineralogical Data."


Tools and Services

  • EarthChem Library v3.2 is released, with the new features to save a submission session if incomplete, search by an IGSN (International GeoSample Number), and improved search for author/person. See the full list of features and bug fixes on the EarthChem Library Release Notes Page.
  • PetDB v.2.8.6 is released, with several new features including an improved sample search, improved book reference citation display, and a bug fix to avoid duplicate inclusion data in the table information view. See the full list of features and bug fixes on the PetDB Release Notes Page
  • MGDS Search v3.0 is released and includes a new map-based search interface, providing faster and more accurate geospatial search capabilities than the text-only search.
  • GMRT v3.0 is available and incorporates processed swath data from 38 additional cruises on 11 research vessels. Additionally, the GEBCO_2014 grid is now used as the new base map in GMRT. An updated South Polar Web Map Service was also released.
  • SESAR v6.3 is released, with new features and improvements including a public/private metadata toggle in the MySESAR sample list, new web services like IGSN return from a map polygon, and a change to a more widely-used UTM syntax. Read more on the SESAR Release Notes Page.



  • New contributed data now available through the GeoPRISMS data portal includes Aleutian arc bathymetry data (Yogodzinski: TN182) and single-channel seismic data in the New Zealand-Macquarie Ridge area (Cande:EW9513).  For the Antarctic and Southern Ocean Data Portal, data sets from six 1999-2015 cruises were contributed. Additions to the Marine-Geo Digital Library include bathymetry from the Sunda Subduction Zone (Henstock: HI1123), Indus fan (Clift: PE300), and Galapagos Spreading Center (White: GSC_White); sidescan and photomosaics from the Mid-Atlantic Ridge (Blackman: AT03-60 and Cann: CD100); and, a compilation of subsidence rates for the oceanic plates (Adam: Subsidence_Adam). Read more.
  • New contributed data now available through the EarthChem Library include a study of organic matter decomposition at scientific ocean drilling sites including DSDP, ODP, and IODP sites (Malinverno and Martinez), as well as multiple datasets about geothermal fluids and volcanic emissions from Central American Volcanoes (de Leeuw et al.; Mather et al.; Snyder et al.; Rouwet et al.)
  • Browse the Recent Data Additions for PetDB (47 new references).
  • SESAR, the System for Earth Sample Registration, worked with the Smithsonian National Museum of Natural History to register over 340,000 samples from the National Gem, Mineral, and Rock Collections with IGSNs. The SESAR profiles link back to the Smithsonian collections web pages. To view these samples, search the catalog for IGSNs beginning with the namespace NHB.


Outreach & Education

  • The first year of the joint IEDA – CCNY (City College of New York) Internship program has been successfully completed this summer. Five undergraduate students from City College participated in the program, completing data intensive tasks in geochemistry and marine geophysics. Read more. 
  • A GeoMapApp webinar was held as part of a series of NAGT-sponsored workshops focused on the use of large on-line databases and resources in the classroom.
