IEDA Newsletter, April 2017, No. 18

This newsletter summarizes new features and improvements in the Interdisciplinary Earth Data Alliance (IEDA) systems. Click on the links below for more detailed information.

IEDA Community

  • New content has been added to the IEDA YouTube Channel including videos that explain how to register samples in SESAR, how to search for content in the Marine-Geo Digital Library, and how to submit data to the EarthChem Library. Additionally, new tutorials were posted on the GeoMapApp YouTube Channel, including a full-length webinar.
  • The IEDA team had a busy week at the AGU Fall Meeting hosting an exhibit booth with demonstrations of our data and software resources; holding a GeoMapApp Users’ Lunch to inform users of recent and upcoming enhancements and gather valuable feedback; and presenting a total of ten talks and posters about IEDA developments, tools, and resources. The 2016 IEDA-CCNY Interns also gave presentations on the results of their work over the summer.
  • Also at the Fall AGU Meeting, IEDA and Elsevier presented the 2016 International Data Rescue Award in the Geosciences to the winning project, “Revealing Our Melting Past: Rescuing Historical Snow and Ice Data.” Read More.

Tools and Services

  • The Elsevier DataSearch Tool has been added to the PetDB web site. Please check it out and send us feedback. Learn more.
  • GMRT v3.3 was released with data from 26 additional cruises conducted in the Southern Ocean (5 cruises), Atlantic Ocean (3 cruises), Indian Ocean (2 cruises), and Pacific Ocean (21 cruises). Also included is the latest International Bathymetric Chart of the Arctic Ocean (IBCAO v 3.0) and a new North Polar Web Map Service (WMS). Learn more about this release here.
  • GeoMapApp v3.6.4 was released. Enhancements to the Profile Tool now allow up to four different grids to be profiled at once. The Save Session functionality has been expanded, and grid manipulation and import functionalities have been improved. Other modifications and bug fixes requested by the community were also made. More Info.


  • New contributed data sets now available through the Marine-Geo Digital Library include:
    • Bathymetry for the Tonga fore-arc, Galapagos Islands, Venice Lagoon, Ross Sea and New York’s Fire Island
    • Gravity data over the Tamu Massif and CTD data for Niua Volcano
    • Juan de Fuca Axial Seamount microseismicity earthquake catalog and interpreted outlines of lava flows and eruptive fissures
    • Down-hold temperature data from Juan de Fuca drill sites
    • View the full list of new data sets in the MGDL
  • New contributed data sets now available through the EarthChem Library (ECL) include:
    • Electron microprobe analyses from Apollo Missions 11 and 12
    • Volcanic gas plume data from multiple volcanic regions
    • Geochemical data from the Critical Zone Observatories
    • Geochronologic data from multiple regions in the Western U.S.
    • View the full list of new data sets in the ECL
  • In the last quarter, 137,448 samples were registered in SESAR. Browse the SESAR catalog.
  • No new PetDB version was released this quarter while we are working on a major system upgrade that will include a new and improved user interface. As part of this effort, we have been gathering user feedback on the current PetDB. Please consider providing feedback by taking this brief survey.
