IEDA Newsletter, May 2019, No. 26

Posted on by

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

  • SESAR will co-host a workshop “Vive les Samples! Geosample data management and visualization for the discerning geochemist!” at the Goldschmidt Conference in Barcelona on August 18th from 8:30 am – 12:30 pm. Please register here. IEDA director Kerstin Lehnert will also co-convene the session, “Harvesting the Power of Data to Advance Science in Geochemistry, Petrology, and Mineralogy“.
  • EarthChem and SESAR presented at the CZIMEA Toolkit workshop, an EarthCube cyberinfrastructure training and tool assessment workshop which aims to bring together tool developers and early career Critical Zone scientists. Please click here to see our slides from the presentation.
  • As Allocating Agent of the IGSN, IEDA’s sample registry SESAR is participating in a major strategic planning effort of the IGSN, funded by the Sloan Foundation and led by IEDA Director Lehnert, to mature the technical and organizational architecture of the IGSN. IGSN2040 meetings were held at the RDA P13 in Philadelphia in March and during the EGU General Assembly 2019 in Vienna.

Tools and Services

  • GeoMapApp v3.6.10 was released. Updates include several bug fixes related to importing grids and to digitizing horizons in the Digital and Analog Seismic Portals. The geochemical data that can be explored through the GeoMapApp PetDB portal was updated to align with the spring 2019 release of the PetDB synthesis. Other bug fixes necessary to maintain GeoMapApp were implemented. Click here for more information.
  • EarthChem Library v.3.6.5 and v.3.6.6 were released. ECL datasets may now be linked to related identifiers and information such as IGSN, Smithsonian Volcano Number, and Cruise DOI. Users submitting to the ECL can now select if they would like to submit their dataset to be reviewed for inclusion in PetDB. This new version also consolidates the DOI and ECL landing pages and allows users to change the release date of their dataset after it has been submitted.
  • New functionality for the Academic Seismic Portal map viewer allows multiple seismic data layers with clickable events to be active simultaneously. Improvements were also made to the interactive layer for IODP-ODP-DSDP seafloor drill hole sites.
  • With our new streamlined data entry and data validation procedures we have significantly increased the speed of data ingestion into PetDB. Since April, 2018 346 new references have been loaded into PetDB, bringing the total number of chemical values to over 4.2 million. Click here to browse PetDB.

Collections

  • New contributed data sets now available through the Marine-Geo Digital Library (MGDL) include:
    • Electromagnetic and magneto-telluric data along the central and southern Mid-Atlantic Ridge
    • Seafloor bottom photographs from the California coastal margin
    • Multibeam bathymetry from the northeastern Pacific including from Barkley Canyon & Hydrate Ridge
    • High-resolution bathymetry from the Chilean Patagonia Baker and Steffen fjords
    • View the full list of new data sets in the MGDL
  • New contributed content now available through the EarthChem Library (ECL) include:
    • Sediment geochemical and geochronological analyses of OC170-26-159, Pacific-Antarctic Ridge
    • Plagioclase/melt partition coefficient experiments
    • Silicate mineral compositions for metamorphic schist and amphibolite, northern Madison Range, southwestern Montana
    • Geochemistry and grain size for sediment core JPC14 from Golfo Elefantes, Chilean Patagonia
    • View the full list of new data sets in the ECL
  • New contributed data sets now available through the U.S. Antarctic Program Data Center (USAP-DC) include:
    • Ground Penetrating Radar Data near Blood Falls, Taylor Glacier
    • South Pole (SPICECORE) 15N, 18O, O2/N2 and Ar/N2 data
    • Organic carbon isotope data from serially sampled Eocene driftwood from the La Meseta Fm., Seymour Island, Antarctica
    • Fjord-Eco_Sediment_OrgC_OrgN_Data
    • View the full list of new data sets in the USAP-DC
  • New contributed data sets now available through the Academic Seismic Portal (ASP) at LDEO include:
  • New data collections available from traceDs:
    • A new EarthChem web page provides access to compilations of experimental mineral/melt partitioning data generated by traceDs. These datasets, published in the EarthChem Library, can help users to calculate differential scenarios, test models, and facilitate experimental design and data management plans. These datasets utilize the traceDs template, a format for documenting experimental data that is available on the EarthChem website for investigator use. Please click here to learn more.
  • Since February 13,233 samples were registered in SESAR. Browse the SESAR catalog.
