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

• Do you have data from your research that you would like to make accessible online in a trusted repository? Join us for a free webinar on how to deposit your data in the EarthChem Library on Thursday May 31st at 2 pm ET. Learn more and register to attend here.
• A USAP-DC webinar was held on May 8th to introduce the different services that USAP-DC offers, including the submission of datasets to the repository, registration of NSF-funded projects with the Antarctic Master Directory (AMD), searching for datasets hosted by USAP-DC and using map-based visualization tools for Antarctic data hosted by IEDA. The webinar can be viewed online here.
• IEDA director, Kerstin Lehnert, recently received the 2018 Ian McHarg Medal of the European Geosciences Union. Lehnert was recognized for her “exceptional contributions to the advancement of informatics and, in particular, her pioneering efforts on open, transparent and reproducible science.” As recipient of the medal, Kerstin gave a lecture entitled “Data Infrastructure for the Earth & Space Sciences: How Far Have We Come, Where Are We Heading?” View the full presentation here.

Tools and Services

• EarthChem Library v3.6.0 was released. The new version allows investigators to link more than one award to their submitted dataset and allows for submission of NSF, NASA, and other award types if needed. This new version also makes use of the NSF Award Web Service to show award metadata, rather than relying on an internal harvest of only a subset of awards. To learn more, see here.
• GeoMapApp v3.6.8 was released. Updates include the new velocity vector portal, improvements to the portal for waypoints and survey lines and to the digitizer function, and enhanced contouring capabilities. Other modifications and bug fixes requested by the community were also made. More Info
• SESAR v7.1.1 was released. The new version allows users to preview sample locations plotted on a map during batch upload. This new feature will help investigators identify potentially erroneous coordinates prior to submitting their registration template, thereby reducing the likelihood of incorrect sample metadata. To learn more, see here.
• USAP-DC now offers a Metadata (DIF) Browser that provides a browsable list of metadata records that have been registered in the Antarctic Master Directory. Records registered through USAP-DC can be searched by title keyword, PI name, Award# and DIF ID. Also, USAP-DC data set pages now include a map display of data set location, and the home page map interface now shows the bounding box for each data set when the data set centroid location is clicked. Map overlays include the LIMA and MODIS image mosaics for the Antarctic continent merged with seafloor bathymetry.
