IEDA Newsletter, August 2017, No. 19

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

  • IEDA Director, Kerstin Lehnert, will lead “Keep Your Samples Alive (and Connected)!”, a free lunch workshop at the 2017 Goldschmidt Conference. To learn more and register, see here.
  • IEDA will have a booth at the GSA Annual Meeting in October. Come visit us at booth #417 to ask questions and learn about the latest IEDA tools and services.
  • A short course about Geochron will also take place at the GSA Annual Meeting. The full-day meeting costs only $30. To learn more, check out session #524 here.

Tools and Services

  • The IEDA Data Browser now contains data from the Academic Seismic Portals (ASP) of LDEO and UTIG.
  • GeoMapApp v3.6.6 was released. Both the Digitizer Tool and the Save Sessions functionality were significantly enhanced, and video tutorials were made for each. Grid import capability was expanded and a wider range of web feature and web mapping services can be imported. Other modifications and bug fixes requested by the community were also made. More Info.
  • GMRT v3.4 was released with new data for the Indian Ocean from the search for Malaysia Airlines flight MH370 as well as new bathymetry for the Gulf of Mexico assembled from 3D seismic data by the U.S. Bureau of Ocean Energy Management. This release also includes data from 43 additional cruises in the Southern Ocean (1 cruise), Atlantic Ocean (10 cruises), Indian Ocean (1 cruise), and Pacific Ocean (36 cruises). Learn more about this release here.
  • SESAR v7.0.0 was released. Among several new features and improvements, the new version allows users to update sample metadata for existing samples in bulk by uploading a batch template. To learn more about this and other new features, see here.

    • Sidescan and AUV near-bottom geophysical data from Loihi Seamount, Barkley Canyon, East Pacific Rise and Papahanaumokuakea Marine National Monument.
    • Paleobathymetry data for North Carolina’s Pamlico Sound.
    • Multi-channel seismic reflection data offshore Chile and from the Eastern North American Margin.
    • Potential field anomaly data from the Mid-Atlantic Rainbow vent field, Reykjanes Ridge and global subduction zones.
    • Seafloor photo-mosaics and CTD data from the Lau back-arc basin and Marianas region.
    • Hydro-acoustic data from the Su Su Knolls vent field and offshore New Jersey.
