  • EarthChem KML for Google Earth

    June 2011: The EarthChem Google Earth KML file provides end-users with an intuitive interface to all EarthChem samples (including NAVDAT, PetDB, GEOROC, USGS, GANSEKI, SedDB, and MetPetDB). To view EarthChem samples in Google Earth, simply load the EarthChem.kml file and zoom to your desired location. There is currently a limit of 1000 samples per page view, but zooming in to a location will provide all samples. To view sample details, click on the individual sample icons.

  • CZChemDB and EarthChem: Critical zone geochemical data.

    June 2011: EarthChem’s affiliates at PennState are presenting a paper at the Ninth International Symposium on the Geochemistry of the Earth’s Surface (GES9), June 2-7 at the University of Colorado, Boulder. The article, published in Applied Geochemistry, describes the CZChemDB, a relational database developed for critical zone rock and regolith geochemical data.

     

    The Penn State group, part of the Susquehanna Shale Hills Critical Zone Observatory, is teaming with EarthChem to make CZChemDB data discoverable by the EarthChem Portal. This connection broadens the scope of EarthChem geochemical data to the critical zone - the Earth’s outer layer from vegetation canopy to the soil and groundwater that sustains human life.

  • New Data Submission Templates

    May 2011: Data Submission Templates [link] have been posted to help authors submit their data to the GfG systems. These templates are customized for different analytical techniques (electron microprobe, mass spec) and materials (bulk sample, mineral, melt inclusion, vent fluid) and help authors to document their data according to the recommendations of the Editors' Roundtable. Authors can also add their own fields to the templates. Instructions and suggested vocabularies are included in these .xls workbook templates.

     

    The templates provide a standardized way to submit data to GfG, including our Geochemical Resource Library (GRL) and the GfG databases PetDBSedDB, and VentDB.

     

    The full list of templates is posted at the EarthChem website: http://www.earthchem.org/data/templates.
