One (1) seat is open on the EC and three (3) seats are open on the SSC. Winners will serve a three (3) year term beginning in January 2021 and ending in December 2023. Ballots have been mailed to your Member Representative . If your institutions is not a member, please inquire on how to become a member to be eligible to vote in future elections. New this year is Ranked Choice Voting. For the EC and SSC Group 3, rank order candidates in order of preference, 1 being your top choice. More information on rank choice voting can be found here: https://ballotpedia.org/Ranked-choice_voting_(RCV) Please see our website for candidate information for this year's election: https://geodynamics.org/cig/about/governance/elections/ Thanks to Carl Tape (EC), David Ham (SSC), Jessica Irivng (SSC), and Gabriele Morra (SSC) for their service to CIG the past 3 years. Elections close: November 23, 2020 Best, -Lorraine ***************************** Lorraine Hwang, Ph.D. - Director Computational Infrastructure for Geodynamics UC Davis 530.752.3656 geodynamics.org -------------- next part -------------- An HTML attachment was scrubbed...

The Committee asked interested parties to focus on the following points: Governance and Structure (single PI versus multiple PIs; centralized or distributed models) Education, Training and Outreach (including Diversity, Inclusion and Equity efforts) Scientific Mission and Priorities (science drivers; community engagement in setting priorities; prioritizing support of community codes) Partnerships with other groups and agencies (including international collaborations and additional funding opportunities). These are the broad themes that emerged from the received submissions: The strongest theme across submissions is that CIG-IV should develop a much more comprehensive education and training program, encompassing a variety of forms and these should be well supported formal efforts. Some examples include: Expand tutorials and hackathons with an emphasis on best practices in modeling and software development Research experiences for undergraduates with a focus on underrepresented minorities Development of teaching modules for use in undergraduate and graduate courses The second strongest theme was the establishment of a formal partnership with a high-performance computing center to provide not only computing allocations but a full modeling workflow. CIG-IV would move away from focusing on solutions of computational forward models to providing a more complete platform for end-to-end modeling and computation, including analysis and post-processing and integration with data both observational and experimental. This partnership would be important for education and training efforts, as well as for diversity and inclusion. No clear visions emerged regarding centralized vs distributed governance. There was a desire for code development to be driven by scientific questions and community wishes, although the exact form for a decision structure remains less clear. One intriguing model proposed was that of a “field” site focused on a particular problem with the participation of all stakeholders including observationalists, experimentalists and modelers/code developers. There was a great desire for partnerships with other entities (NASA, DOD, DOE, CSDMS, SCEC, Industrial, International). ____________________________________________________________________________ We invite you to continue the discussion on the CIG forum (community.geodynamics.org ). Updates will be posted on the forum as the EC incorporates this report and Workshop feedback in setting the course for CIG IV. -------------- next part -------------- An HTML attachment was scrubbed...

Nov 12 @2P PT Message-ID: <407C5032-4EDE-4CE6-93CB-A659CEC46AB4@ucdavis.edu> THURSDAY NOVEMBER 12 @ 2P PT Numerical models of lower crustal flow explain Yellowstone's "tectonic parabola" Jonathan Perry-Houts, UC Davis Several hypotheses exist for the origin of the seismically active region of high topography surrounding the Yellowstone hotspot track. Among these is the idea that a dense mid-crustal sill has driven viscous lower crust away from the hotspot track, producing crustal thinning/subsidence in the Snake River Plain, and corresponding inflation/uplift of the surrounding terrain. Recent evidence of azimuthally-aligned seismic anisotropy in the lower crust has led us to investigate the dynamics of lower crustal flow, and its role as a non-tectonic driver of localized epeirogeny. In this GIG webinar, I will describe ongoing work to quantify this mechanism, including an efficient numerical method for modeling lower crustal flow, and its potential application to geodynamic models.
