EarthChem Newsletter, February 2019, Vol 1

February 2019. This newsletter summarizes new features and improvements at EarthChem as well as recent community engagement and featured datasets. To subscribe to future quarterly newsletters please click here.

Recent Improvements

  • EarthChem Library (ECL) version 3.6.4 was released. This new version allows users to select the Creative Commons license that they would like to associate with their dataset. Users can now choose between four different licenses, providing more flexibility for users to allow reuse for commercial purposes or to make the dataset public domain. See more release notes here.
  • The PetDB Search application has been completely redesigned to allow for easier data searching and integration. This new version enhances usability and supports new functionality such as: search by chemical composition; expanded map search, including a southern polar projection; search by age; search by International Geo Sample Number (IGSN); and plotting data as TAS and Harker diagrams. Please write to us at with any feedback or comments.

Featured Datasets

  • Major element data for olivine, orthopyroxene, and spinel within peridotites from the Southwest Indian Ridge. View in the ECL.
  • Characterization of plagioclase hosted melt inclusions in A91-1R (Blanco Transform Fault). View in the ECL.
  • LA-ICP-MS apatite fission track and U-Pb dataset for southern Baffin Island, Nunavut, Canada. View in the ECL.
  • Hadean silicate differentiation preserved by anomalous 142Nd/144Nd ratios in the Reunion hotspot. View in PetDB.
  • Extensive young silicic volcanism produces large deep submarine lava flows in the NE Lau Basin. View in PetDB.
  • Mantle source heterogeneity for South Tyrrhenian magmas revealed by Pb isotopes & halogen contents of olivine-hosted melt inclusions. View in PetDB.

EarthChem Community

The EarthChem Team attended the AGU Fall Meeting held in Washington D.C. See more information below about our presentations at AGU, which included presentations about open and FAIR Data and participation in a Townhall regarding geochemical data standards. If you were not able to catch up with us at AGU, contact us at with questions or comments about our resources.

  • Building a Global Network of Geochemical Data: This Townhall discussed developing geochemical data standards in the Earth Sciences and opportunities for a global geochemical data network. To learn more, please refer to the presentation here

  • Boosting Data Science in Geochemistry: We Need Global Geochemical Data Standards and Networking!: In this presentation, Dr. Lehnert talked about how can we develop global standards that would allow for connecting and exchanging data among the geochemical data systems. The presentation can be found here.

Building a Global Network of Geochemical Data (AGU Town Hall)

December 2018. Please join us December 11th at AGU for a one hour town hall discussing the development of geochemical data standards and ideas for a global geochemical network.

Future science endeavors in geochemistry, petrology, mineralogy, and volcanology will increasingly rely on access to and analysis of large volumes of data as data science is emerging as a new research paradigm in these fields (see session V017 of the 2018 AGU Fall Meeting). Data systems such as EarthChem and GEOROC have provided access to global, though thematically focused data syntheses. More geochemical data systems are emerging at national, programmatic, and subdomain levels in response to Open Access policies and science needs, and many other data systems and repositories manage geochemical data. There is an urgent need to develop and implement global standards and best practices for geochemical data to become FAIR (Findable, Accessible, Interoperable, Re-usable), and to establish standard protocols for exchanging geochemical data among distributed data systems. This Town Hall aims to engage relevant communities in the Earth sciences in defining and planning steps toward the development of geochemical data standards as well as exploring ideas and opportunities for a global geochemical data network that facilitates and promotes discovery and access of geochemical data through coordination and collaboration among international geochemical data providers. The goal is converge on a common vision for such a global geochemical data network.

December 11, 2018, 6:15-7:15 pm, Marriott Marquis, Room: Independence E

Beta launch of the new PetDB Search

November 2018. EarthChem is pleased to announce the release of the beta version of the new PetDB. This version of PetDB is designed on a brand new architecture, which features a more flexible database schema and user interfaces, with improved support for data searching (e.g., by chemical composition) and interoperability (e.g., with MELTS). The old PetDB Search will be retired and replaced by the new version in January 2019.

Please provide feedback on the new PetDB to help us improve the system by contacting us at

Data Management Planning Workshop at Goldschmidt 2018

July 2018. Please join us for a 1-hour IEDA:EarthChem workshop/tutorial on data management planning at the Goldschmidt Conference in Boston.

Workshop Description:
Data management plans (DMP) are now required by federal funding agencies (NSF, NIH, etc.) with all new grant proposals. This workshop, geared toward faculty and researchers, will provide guidance for creating a data management plan and demonstrate online tools that support and facilitate the generation of high-quality DMP and Compliance Reports, including the IEDA DMP ToolezDMP, and the IEDA Data Compliance Reporting Tool. Please register for the workshop here.

When?  Thursday, August 16, 2018, 1-2PM

Where? Hynes Convention Center, room 108

The workshop is supported by the US National Science Foundation.

For questions, please contact Kerstin Lehnert (

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 Please contact us at

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