EarthChem Library Webinar: How to Contribute Data

May 2018. 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. Register to attend here. If you are able, please also complete this 2 minute survey to help us adapt the webinar to audience interests.

The EarthChem Library (ECL) is an NSF-funded open-access repository for datasets (analytical data, experimental data, synthesis databases) and other digital resources relevant to the fields of geochemistry, geochronology, petrology, and mineralogy. The ECL offers a complete suite of services for data preservation and access, including long-term archiving, registration of data with Digital Object Identifiers (DOIs), and links to publications. The ECL recommends use of data type specific templates that have been developed in collaboration with researchers who work closely with the data types. These templates provide guidance to investigators on the inclusion of key sample and analytical metadata that maximize reusability and discoverability of the datasets. We welcome collaborations to generate templates for new data types.

The ECL has been recognized by funding agencies and publishers as a trusted repository for fulfilling Data Management requirements. To learn more, see www.earthchem.org/library. Please contact us at info@earthchem.org.

A recording of the webinar can be viewed on our Youtube channel.



Undergraduate Projects Improve Analysis of Geochronological Data

Feb 2018. Undergraduate students in the Computer Sciences Department at the College of Charleston are developing open-source software applications and infrastructure aimed at improving access to and analysis of geochronological and other earth-science data. The students are working under the direction of Dr. Jim Bowring at the Cyber Infrastructure Research & Development Lab for the Earth Sciences (CIRDLES). Four of the students recently presented their work at the 2017 Geological Society of America Annual Meeting. Topsoil is highlighted below. 

Topsoil: A community driven open source replacement for ISOPLOT

Topsoil is a desktop application and Java library that creates data visualizations for geochronological data. “Topsoil” is an anagram of “Isoplot”, an enormously successful Microsoft Excel Add-In with similar capabilities that now works only in older versions of Excel. Using Topsoil, a user is able to import or manually enter data, which is stored in tables that can be organized and edited by the user. The table is used to create a plot that is freely explorable, and with several built-in plot features that can be toggled on or off, such as uncertainty and concordia line. Plot features are dependent on the isotope system of the given table. Current options are Uranium-Lead or Uranium-Thorium analyses, and more isotope systems will be available to the user in the future.

Advancement of Topsoil depends on the active involvement of the community to guide development and for assistance with design and coding, specification of capabilities, and develpment of help resources. Contributions to Topsoil can be made at https://github.com/cirdles/topsoil.



New EarthChem Library Video Tutorials

Apr 2017. Multiple EarthChem Library video tutorials have been released on the IEDA YouTube Channel. The videos are aimed at simplifying the data submission process and addressing frequently-asked questions. We plan to continue to grow our video tutorial collection, so please keep an eye on the EarthChem Library YouTube Playlist for more. Tutorials will also be posted at http://www.earthchem.org/library/help. If you have questions or suggestions for new tutorials, please contact us at info@earthchem.org.



Elsevier DataSearch Tool Augments Existing PetDB Search

Jan 2017. You can now use Elsevier DataSearch to search and browse PetDB data using the search box (pictured below) on the top right-hand corner of the PetDB homepage (www.earthchem.org/petdb). You may use free text to search. Elsevier DataSearch allows you to preview datasets within PetDB and then, if you wish, allows you to proceed to that dataset in PetDB.

 

The primary goal of the Elsevier DataSearch Tool is to help investigators "find research data across domains and types, from many domain-specific, cross-domain and institutional data repositories." Learn more and search for datasets and publications across repositories, including PetDB, here. Test it out and let us know what you think at info@petdb.org.
