Tools and Services

  • SESAR v.7.1.2, v.7.2.0, and v.7.2.1 were released. Among new feature and enhancements, the new releases added “Experimental Specimen” as an accepted object type, improved error message clarity and documentation, and added deleted sample(s) to the MySamples count. See more release notes here.
  • USAP-DC has updated their dataset submission web forms to allow for multiple award entries and with a better mechanism to capture author names.
  • The PetDB Search application has been completely redesigned to allow for easier data searching and integration. The new version of PetDB will be released in late November 2018.
  • GMRT v3.6, to be released later this month, will include 1.25 million square km of new multibeam data from 38 research cruises conducted throughout the global oceans.
