Workshops

Saturday 11 August – Sunday 12 August

Computational thermodynamics and fluid dynamics with the ENKI software portal: An introduction aimed at early career researchers
Sa 09:00–Su 17:00 CAS 201, Boston University
BOOKING FOR THIS WORKSHOP CLOSED ON 12 JULY. This workshop will provide a hands-on survey of software and modeling tools available at the ENKI-portal. ENKI is an on-going project funded by the National Science Foundation that provides software tools and a computational ecosystem for geochemical simulations that are based on thermodynamics and fluid dynamics. ENKI is aimed at students and researchers interested in using, creating, and maintaining models and in developing interconnected scientific modeling frameworks. We will introduce the capabilities of ENKI and demonstrate how thermodynamic calculations like phase diagrams, pseudosections, geothermobarometers, and mass transfer calculations (MELTS, EQ6, DEW) can be rapidly and easily computed. We will also show how thermochemical databases can be utilized to support fluid dynamical simulations. ENKI currently supports a number of thermodynamic databases and solution model collections, including those of Berman, Holland and Powell, Stixrude and Lithgow-Bertelloni, MELTS, DEW and SUPCRT. Participants will learn how these databases can be extended or recalibrated in light of new data or insights using the model calibration infrastructure provided by ENKI. Attendees will need a laptop for this workshop for real-time access to the ENKI server portal.

Sunday 12 August

Data Science in Geochemistry
09:00-17:00 CAS B06B, Boston University
(Fully booked) The rapidly growing volume of geochemical data that are accessible in online synthesis databases and the availability of new information and computing technology together provide geoscientists with new ways to explore, mine, visualize, and analyze geochemical data. This workshop is intended to provide opportunities for researchers, especially early career scientists, to learn about geochemical data resources and tools for mining, visualizing, and statistically analyzing the data, and to explore additional software tools and data resources that advance data science in geochemistry. The workshop will include brief introductions to fundamental aspects of geochemical data management and data access in geochemistry, and provide time for participants to think creatively and design new ways to use and interact with the data and develop research applications. Participants will be encouraged to contribute scientific use cases around which breakout groups can form. The price is $40 and $20 at the student rate.

Tuesday 14 August

Astromaterials Data System
13:00–13:45 Hynes Convention Center, room 204
The Astromaterials Acquisition and Curation Office (AACO) at NASA Johnson Space Center (NASA-JSC) is starting the development of AstroDB as a comprehensive data system for analytical data generated by the study of all Astromaterial collections curated by NASA-JSC’s AACO, based on and expanding the current MoonDB data system for lunar samples. This Town Hall invites interested researchers who work with astromaterials to learn about MoonDB and the plans for AstroDB, provide input to its design, and engage in its development. Please contact Kerstin Lehnert (lehnert@ldeo.columbia.edu) for more information .

Thursday 16 August

Data Management Planning with EarthChem
13:00–14:00 Hynes Convention Center, room 108
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 Tool, ezDMP, and the IEDA Data Compliance Reporting Tool. Please register for the workshop here. Please contact Kerstin Lehnert (lehnert@ldeo.columbia.edu) for more information. The workshop is supported by the US National Science Foundation.
