IEDA Newsletter, November 2017, No. 20

Posted on by

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 invites you to attend a lunchtime gathering at AGU about IEDA Data Resources for Antarctic Science. Graduate students, post-docs and faculty are encouraged to attend. A $10 Starbucks gift card will be given to the first 40 people who sign up and attend. Sign up soon to claim a place! See more details at the IEDA @ AGU page.
  • Join us at IEDA booth (#1519) at AGU. Come by or schedule an appointment with us to learn about our systems.
  • IEDA will also participate in the AGU Data Fair, a series of sessions and events designed to help scientists improve their data skills and practices. IEDA will host demos and answer your questions at the Data Help Desk. Find more details here.

Tools and Services

  • A new version of GMRT MapTool was released providing the ability to export grids from the GMRT South Polar and North Polar compilations. Users can now explore the the Polar versions of GMRT in a web browser, select an area of interest, and generate a GeoTIFF formatted grid file which can be imported into a variety of software platforms for additional analysis. The web services that drive these new components were also developed and published, and the code for the GMRT MapTool User Interface is now publicly available through GitHub.
  • The Marine-Geo Digital Library Search v3.1 was released and includes several enhancements based on usability tests and user feedback.

Collections

  • New contributed data sets now available through the Marine-Geo Digital Library include:
    • Cascadia subduction zone heat flow and bottom-simulating reflector data.
    • Aeromagnetic data from the East African Rift System.
    • ROV seafloor photographic data from the Lau back-arc basin and Drake Passage.
    • Bathymetry data from Shatsky Rise, Johnston Atoll, the Aleutian arc and Mariana arc.
    • CHIRP sub-bottom profiler data from the Beaufort Sea.
    • Potential field anomaly data, crustal age and bathymetry for the East Pacific Rise between 12N-16N and shallow mantle seismic tomography velocity data from the EPR 9N study area.
    • Experimental tri-axial rock pressure and permeability data on crack initiation and propagation.
