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 Team-members will be at the Goldschmidt Workshop in Boston, MA (Aug 12-17th):
  • Data Management Planning Event: Join a 1-hour session run by IEDA:EarthChem on how to create better data management plans on Thursday August 16th. Learn more here.
  • Data Science in Geochemistry Workshop: This workshop organized by IEDA:EarthChem is intended to provide opportunities for researchers, especially early career scientists, to learn about geochemical data resources and tools for mining, visualizing, and statistically analyzing the data, and to explore additional software tools and data resources that advance data science in geochemistry. Note: this workshop is fully booked, but if you are interested in learning more about it or setting up a time to meet with us in-person or virtually, please contact info@earthchem.org.
• Frank Nitsche recently shared new updates to USAP-DC and the USAP-DC website at the POLAR2018 conference, a joint event hosted by the Scientific Committee on Antarctic Research SCAR and the International Arctic Science Committee IASC in Davos, Switzerland.

Tools and Services

• EarthChem Library v.3.6.1 and v.3.6.2 were released. Among new feature and enhancements, the new releases enable automated semi-annual email notifications to users with download statistics for their contributed datasets. See more release notes here.
• We have recently been recruiting scientists to test and give feedback on our systems, including the Academic Seismic Portal and the IEDA Integrated Catalog. Feedback will be used to guide future  enhancements. If you are interested in taking part in a usability study, please contact info@iedadata.org.
