IEDA Community

  • On February 22, 2016, IEDA submitted a 60 page proposal to the NSF that lays out plans and budgets for the operation of the IEDA data facility over the next 5 years.
  • IEDA Director Kerstin Lehnert co-authored a Science Policy Forum on "Liberating field science samples and data" that was published in the March 4 issue of Science (McNutt et al., 2016). The authors assert that transparency and reproducibility are key to showing the integrity of scientific results, and that access to samples and data needs to go beyond "data and samples are available upon request." The article further emphasizes that the value of preserved data is best maximized by discipline-specific repositories through services informed by community priorities. Although researchers, funders, publishers, and repositories each have differing motivations for promoting transparency and reproducibility, these stakeholders can work together to increase sample and data accessibility.

Science Policy Forum 351, 1024-1026 (2016). doi: 10.1126/science.aad7048.
  • IEDA's Kerstin Lehnert and Lulin Song are co-authors on a new publication entitled, "Observations Data Model 2 (ODM2): A community information model for spatially discrete Earth observations." ODM2, which Lehnert and Song helped to develop, enables more reliable integration of data across scientific domains, including both sensor- and specimen-based data. Current EarthChem systems helped to inform the design of ODM2. In turn, ODM2 forms the basis for the new EarthChemDB that is now under development. Read more.
  • At the Fall AGU Meeting, the IEDA team hosted an IEDA exhibit booth that included demonstrations of geochemical and geophysical resources as well as tools for PIs. At the GeoMapApp Users’ Lunch, recent and upcoming advances were shown, with attendees providing valuable feedback. As part of the AGU Scientific Program, ten presentations were given by IEDA team members on IEDA developments, tools, and resources.

Tools and Services

  • IEDA Data Browser v2.1 was released in February 2016. This release includes a new South Polar view for discovering data in Antarctica and the Southern Ocean. With this release also comes new capabilities to display and interact with multiple layers at once and to draw search areas with polygons in addition to boxes. The IEDA Data Browser showcases many of IEDA's web services that can be used to provide direct access to data and metadata. Stay tuned for additional content in the Data Browser in the months to come!
  • New Point and Profile services allow topographic profiles and point elevation values to be extracted from the GMRT synthesis. These services are integrated in the GMRT MapTool and available as web services. Another new web service, for searching metadata and downloading data files from the Marine-Geo Digital Library, was also released.
  • A new release of Google's Ocean base map includes updated content from GMRT. The ~100m resolution GMRT synthesis now covers about 8% of the global ocean area. GMRT was also added as an optional base map layer in the NOAA NCEI Bathymetric Data Viewer. Read more.


  • New contributed data sets now available through the Marine-Geo Digital Library include sea bottom pressure data at Juan de Fuca Axial Seamount (Chadwick, JdF:Axial_Deformation), CORK down-hole pressure gauge data for Cascadia (Fisher, AT18-07 and AT26-03) and the Mid-Atlantic Ridge (Villinger, MSM-37), and experimental flume tank Doppler velocity data (Lamb, ExpInvestig_Lamb). Bathymetry data for the Tyrrenhian Sea (Petersen, M86-4), Eastern North American margin (Calder, MGL1512), and Scott Reef (Pizarro, FK150324) was added, along with ROV photos of Timor Sea reefs (Ivey, FK150410), Gulf of California magnetics data (Lizarralde, EW0210), and New Zealand Hikurangi margin heat flow data (Harris, RR1508). For the Academic Seismic Portal, full resolution seismic shot data was registered for the Chicxulub Crater area offshore the Yucatan Peninsula (Gulick, EW0501), and high-resolution multi-channel seismic shot data was added for the Hikurangi subduction zone (Harris, RR1508). Read more.
  • Data sets recently registered in the Antarctic and Southern Ocean Data Portal were acquired near the Antarctic Peninsula (Reiss, NBP1507, and LMG1508) and across the far South Pacific (NBP1504). Read more.
  • New contributed data now available through the EarthChem Library (ECL) include geochemical analyses of sediments collected at the ODP Leg 174AX Bass River Site (Quan), geochemical and mineralogical data from soils of Northern Chilean Patagonia (Vandekerkhove et al.), and data from laboratory experiments examining the effect of mineral spatial distribution on magnesite dissolution rates (Salehikhoo et al.).
  • Browse the Recent Data Additions for PetDB (54 references and >68,000 analytical values added).
  • In the last quarter, 7,940 new samples were registered in SESAR. Browse the SESAR catalog.

Outreach & Education

  • IEDA will host a Columbia University student intern through Columbia's Earth Institute Internship Program. Selected from a pool of very talented applicants, John Verghese has begun to work closely with IEDA's Lulin Song to develop a SESAR mobile app.
