IEDA Community

  • It was a busy AGU conference for the IEDA Team and we enjoyed engaging with many of you at our presentations, sessions, and town halls! IEDA team members gave several presentations on IEDA resources and developments. If you were not able to catch up with us at AGU, you can always contact us at with questions or comments about our resources. Some highlights:

Tools and Services

  • SESAR v.7.2.2 was released. This version introduced improved validation and new functionality for the Sub-Object Type and Classification fields and implemented a new version (4.0) of web service schema. See more release notes here.
  • The PetDB Search application has been completely redesigned to allow for easier data searching and integration. This new version enhances usability and supports new functionality such as: search by chemical composition; expanded map search, including a southern polar projection; search by age; and search by International Geo Sample Number (IGSN). Please write to us at with feedback and comments.
  • EarthChem Library v.3.6.4 was released. The new version allows users to choose the Creative Commons license that they would like to associate with their dataset. The new version also improves the handling of long-term archiving and the automation of download statistics sent to users.
  • GMRT version 3.6 was released with curated multibeam data from 38 additional cruises bringing the total number of cruises in GMRT to 1,046. Data sets in this release are from the Southern Ocean (6 cruises), Atlantic Ocean (17 cruises), Indian Ocean (7 cruises), Pacific Ocean (15 cruises), MAR (2 cruises), Lau (2 cruises), IBM (1 cruise), Eastern North American Margin (7 cruises), Alaska:Aleutians (4 cruises). New gridded data includes the new 2018 EMODnet Bathymetry compilation, the new US Law of the Sea grids on the Atlantic Margin, and a gridded compilation from Alaska.
