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

• This month at the Goldschmidt Conference in Barcelona, SESAR will co-host a workshop, “Vive les Samples! Geosample data management and visualization for the discerning geochemist!”.  IEDA director, Kerstin Lehnert, will co-convene the session, “Harvesting the Power of Data to Advance Science in Geochemistry, Petrology, and Mineralogy“, and co-present a talk, “How Can We Sustain Geochemical Databases into the Future?“.
• Frank Nitsche represented USAP-DC at the annual meeting of the Standing committee of Antarctic Data Managers (SCADM) in Brussels in May 2019. SCADM is advising and coordinating Antarctic data sharing practices as part of the Scientific Committee on Antarctic Research (SCAR).

Tools and Services

• SESAR v7.3.0 was released. This version introduced improvements to SESAR’s sample search and added additional security checks for requests to contact sample owners. Updates also included several bug fixes, particularly with respect to sample registration validations. See more on our release notes page.
• USAP-DC is now providing project pages for single and collaborative NSF awards of the US Antarctic Program with links to datasets hosted at different repositories, including the USAP-DC repository. The search functionally was also improved to support searches for projects and datasets simultaneously.
• The Academic Seismic Portal interactive map now presents a layer for the USGS-hosted National Archive of Marine Seismic Surveys (NAMSS) which includes continental shelf and Exclusive Economic Zone 2-D multi-channel seismic data acquired by the oil industry, USGS and BOEM.

Collections

• New contributed data sets now available through the Marine-Geo Digital Library (MGDL) include:
  • GPS-derived geodetic velocity field solutions for East Africa.
  • Gravity and magnetics data from the Shatsky Rise and Hawaiian-Emperor Seamounts.
  • High-resolution bathymetry from the Monterey Canyon and from the Venice Lagoon.

• Since May, 7,814 samples were registered in SESAR. Browse the SESAR catalog.

Outreach & Education

• Last semester, Earth Institute intern John Richardson worked with EarthChem to find and match thousands of IGSNs to samples in PetDB. He also helped to digitize files for data rescue and future inclusion into PetDB. Please reach out to us if you are interested in interning with EarthChem at info@earthchem.org.
