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

• We presented new updates on USAP-DC and especially the new project pages at the West Antarctic Ice Sheet (WAIS) workshop in Julian, CA.
• Usage and impact of EarthChem continues to grow. Data submissions have quadrupled in the past quarter and citation of EarthChem systems in the literature including the PetDB database has reached a new record high over the past year (147 citations).
• Join IEDA events at the AGU Fall Meeting 2019!
  • SESAR User Forum. Sunday, Dec 8, 2 – 4pm, Pacific Heights room at Cartwright Hotel Union Square.

Tools and Services

• USAP-Dc has introduced new editing functions to their project and dataset catalog that allows users to update the metadata records, including updating the list of references related to a dataset or project.
• GMRT version 3.7 was released with curated multibeam data from 62 additional cruises bringing the total number of cruises in GMRT to 1,108. Data sets in this release are from the Southern Ocean (10 cruises), Atlantic Ocean (25 cruises), Indian Ocean (7 cruises), Arctic Ocean (4 cruises), and Pacific Ocean (17 cruises). Learn more about this release here.

Outreach & Education

• A GMRT webinar was held to provide an overview of GMRT, a description of data cleaning processes and data assembly techniques, methods for accessing and downloading maps and grids, and future plans.
• Join us on Twitter (@iedadata, @earthchem, @igsn_info), Facebook (GeoMapApp, EarthChem), and YouTube (iedadata, geomapapp).
