Love, USGS Geomagnetism Program *Abstract:* Electric fields induced in the Earth’s conducting interior during magnetic storms can interfere with the operation of electric-power grid systems. In extreme cases, these geoelectric fields can damage high-voltage transformers and cause blackouts. Maps of extreme-event geoelectric amplitude can help utility companies evaluate the vulnerability of their systems to this ground-level space-weather hazard. We discuss the construction of such maps using data from the EarthScope magnetotelluric survey and from long-operating magnetic observatories. This project is a collaboration between solid-Earth and space-physics scientists, and it is motivated by the U.S. National Space Weather Action Plan. After registering, you will receive a confirmation email containing information about joining the webinar. NOTE: Registration does not confirm or guarantee you will have a spot during the webinar, as we are limited to 100 participants.

Session Description: Geodesy’s ability to image earth processes has vastly improved both spatially and temporally in recent decades, making it an essential tool to study the seismic cycle and the ways the earth accommodates tectonic strain. To use geodesy to image these processes in a complex earth, it is essential to 1) correctly separate the contributions made by seismic, aseismic and nontectonic deformation in the data, and then 2) link these observations to fault and bulk processes with a full view of their spatiotemporal complexities. We welcome studies on all aspects of geodetic imaging of the seismic cycle: from improved techniques to detect tectonic signals (e.g. probabilistic, sparsity-promoting, etc.) and separate them from other deformation sources (e.g. hydrological, thermoelastic, anthropogenic), to the modeling and interpretation of the deformation mechanisms that produce them (e.g. coseismic slip, afterslip, viscoelastic relaxation, poroelastic rebound, slow slip events, long-term creep, gravity-driven postseismic deformation). Conveners:Christopher Rollins, Caltech Adriano Gualandi, CaltechMong-Han Huang, NASA Jet Propulsion LaboratoryJessica R. Murray, USGS Menlo Park Feel free to send any questions or comments to me at jcrollin at caltech.edu or to any of the co-conveners, and we hope to see you there! As a reminder, the abstract submission deadline is 11:59 PM Eastern Standard Time on August 2.

At subduction plate boundaries, vast quantities of fluid are exchanged between the Earth, ocean and atmosphere; however, water transport through subduction zones is only partially understood. Volatile cycling is fundamental to the petrogenesis and eruption of arc magmas. Fluids and dehydration reactions may also play a key role in the earthquake cycle. This session will address some key scientific questions of volatile cycling. What is the role of the slab mantle as a vessel for transporting water into the subduction zone? What are the pathways of volatiles through the subduction system thereby impacting geodynamic processes (e.g. mantle flow)? How are volatile pathways manifested in seismic, volcanic and mineralization potential?

On behalf of all session conveners, I invite you to submit to our 2017 Fall AGU session: DI002: Advances in Understanding Earth's Dynamic Processes using Seismic Anisotropy Session Description: Understanding the process and evolution of mantle dynamics represents a fundamental goal of Earth science. However, this has also been a major challenge due to the inaccessible nature of the solid Earth and the various uncertainties in observation and modeling. Recent advances on measuring seismic anisotropy using different geophysical methods generate new constraints on deformation of the Earth’s interior associated with active subduction, lithosphere deformation, mantle circulation, core-mantle boundary processes, as well as the growth of the inner core. Meanwhile, novel analog and numerical modeling techniques and capabilities start to be able to capture the Earth’s dynamic processes at unprecedented levels of resolution and physics. Consequently, new perspectives emerge on the evolution of the crust, lithosphere, mantle, and core. Therefore, we invite submission with a focus on the deformation and structures of the solid Earth from seismic and MT measurements, laboratory simulation, theoretical calculation, and geodynamic modeling.

As computation and the influx of digital data are becoming an integral part of our science from the surface to the core, please consider submitting an abstract to this session and share your results and/or numerical approaches! Abstracts are due by Wednesday, August 2. Session details are included below. We look forward to seeing you in New Orleans this December, Juliane Dannberg, Jed Brown and Marc Spiegelman *DI001: Advances in Computational Geosciences *(ID #26637) https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26637 This session highlights advances in the theory and practice of computational geoscience, from improvements in numerical methods to their application to outstanding problems in the Earth sciences. Common issues include robust and efficient solvers, multiscale discretizations, design of benchmark problems and standards for comparison. Increasing data and computational power necessitates open source scientific libraries and workflow automation for model setup, 3D feature connectivity, and data assimilation, and automation in uncertainty representation and propagation, optimal design of field studies, risk quantification, and testing the predictive power of numerical simulations. By bringing these crosscutting computational activities together in one session, we hope to sharpen our collective understanding of fundamental challenges, level of rigor, and opportunities for reusable implementations. Contributions from all areas are welcome, including, but not limited to, fault modeling, tectonics, subduction, seismology, magma dynamics, mantle convection, the core, as well as surface processes, hydrology, and cryosphere.

The submission deadline is August 2nd. >>>>>>>>>>>>>>> DI010: Linking interior evolution, dynamics, and surface signatures across planetary scales Measurements of the deep interior cannot be made directly but surface measurements such as gravity, topography, volcanism, and sea-level, give insight into the motion inside. These measurements provide necessary constraints on the mechanisms governing the dynamics of the deep interior, from relatively small scales, such as those linked to mantle plumes, to the longest planetary wavelengths. Earth's present-day surface is a snapshot in time that displays the integrated signal of multiple processes that operated at different times with varying intensity and duration. The same is true of other planetary surfaces. Linking such temporal and spatial scales is thus crucial to understanding planetary history, not only on Earth, but also on other planetary bodies. This session aims to shed light on these spatial and temporal links using multiple approaches including mantle flow modelling, seismology, data inversion and others. We welcome theoretical, numerical, laboratory and observational contributions from all relevant disciplines. <<<<<<<<<<<<<<< Confirmed Invited Speakers: Anne Davaille, CNRS / University Paris-Sud, FAST, Orsay, France Matthew Weller, University of Texas at Austin Convenors: Keely O’Farrell, University of Kentucky Tobias Rolf, University of Oslo Mingming Li, Arizona State University; University of Colorado at Boulder With apologies for any duplicate postings.

Session Title: *DI004. * *Connecting the evolution of the Earth's magneticfield and the dynamics of the deep interior* Co-Organized with: Study of Earth's Deep Interior, and Geomagnetism, Paleomagnetism and Electromagnetism https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session23048 Observations of the Earth's magnetic field provide a window into the internal dynamics of the deep interior. Advances in paleomagnetic, archeomagnetic, observatory, and modern satellite measurements reveal that the geodynamo is ancient and seemingly persistent, yet the detail of how it operates and manifests in changes on yearly to millennial to million year timescales remain poorly known. Modelling the conditions representative of Earth's core remain challenging, yet it is only by constraining such models with observations that a complete understanding of the core will emerge. This session seeks to bring together perspectives from the observational community with those from the modelling community to convene on the state of the geodynamo and its evolution. We invite contributions that advance our understanding of the evolution of the field - from paleomagnetic to modern measurements - along with numerical models or theory that provide insight into the deep interior's history and dynamics.
