I would like to add one more recommendation to your list. The session DI018 has been organised in recognition of the lifetime’s work of Louise Kellogg. This is one of the Centennial sessions and, as such, is freely available to all contributors and does not prevent you submitting to a specialist session elsewhere in the meeting. We strongly urge all members of CIG who are planning to attend the meeting to add this session to your calendar and to consider submitting an abstract. The session description follows. Louis Moresi (on behalf of all the conveners) (PS - feel free to forward this message) DI018: Understanding Global Dynamics of the Earth's Mantle: a Multi-Disciplinary Endeavor As the centennial celebration for AGU draws to a close, we look toward the future of understanding the dynamics of the deep earth. Unraveling past and present global scale dynamic processes in Earth's mantle, and how they relate to plate tectonics and other geophysical and geochemical surface observations, requires combining insights from different disciplines, all linked together through geodynamic modeling and laboratory experiments. This session welcomes submissions that contribute cutting-edge parts to the puzzle, including but not restricted to seismic imaging, mineralogy and petrology, major and trace element geochemistry, and, importantly, geodynamical studies addressing thermo-chemical convection and mixing in the earth's mantle, including the development of novel numerical computational and visualization methods as well as community integrative efforts. We encourage submissions embracing open, interdisciplinary systems science and representing both method development and key science advances, such as exemplified by the career of Louise Kellogg.

Session title: DI016. The Geodynamics of Cratons Session abstract: Being the oldest lithosphere, cratons have experienced the consequences of complex geodynamic processes that have operated since the Archean. These thick, cold and old lithosphere provide us with a way to study the Archean earth. Moreover, their unique lithospheric properties often influence present-day lithosphere-mantle interactions. The reason behind cratons' long-term survival is one of the most outstanding questions in Earth Sciences and was first addressed in the mid-70s. However, a definitive explanation is still elusive. The other issues associated with the cratons, such as their origin, density and viscosity structure, thickness, chemical heterogeneity and destructive mechanisms can be probed using numerical modeling, field data, geochemical studies and seismic imaging. Recently, the discovery of mid-lithospheric discontinuity has added more complexity to the craton problem. In this session, we welcome contributions that intend to investigate the geophysical and geochemical problems related to cratons, both at the global and regional scales.

The AGU abstract portal is open for submissions and the deadline is July 31st. * * *Session Description:* In the last few decades seismic observations have revealed the structure of the mantle in ever increasing richness. Mineral physics experiments and theory have been uncovering new phase transitions, characterizing changes in the valence and spin state of iron, and determining element partitioning behavior in mantle phases. Concurrently, advances in seismology and geodynamic modeling have been building a consistent picture of Earth in which mantle structures can be identified and their importance to mantle dynamics can be understood. We now have evidence of seismic structure that is consistent with thermodynamically controlled processes, thermal variations due to mantle convection and petrological variations possibly due to partial melting, primordial reservoirs, mantle segregation and recycling. We seek contributions in experimental, theoretical and observational fields, including seismology, petrology, mineral physics, geochemistry and geodynamics, which investigate the nature and role of phase transitions in the structure and dynamics of Earth's interior. * * *Primary Section/Focus Group: * Study of Earth's Deep Interior *Invited Presenters:* Antoniette G.

There were some immediate and urgent decisions that we had to make quickly such as the need to appoint an interim director and a PI for the CIG grant to UC Davis. As we previously mentioned, the EC was pleased to accept earlier advice from Louise that Magali Billen would be an excellent interim director in her absence. The EC would like to express our particular thanks to Lorraine Hwang for taking on many additional tasks to keep the organisation running smoothly for the past few months. We also recognise that all CIG staff have found themselves with additional work and this is likely to be true for a few months yet. Thank you to you all. The EC also spent some time considering the medium term needs for CIG (the remaining two years of CIG-III) and the longer term (CIG-IV and beyond). We met at UC Davis on June 17th and 18th to review the state of CIG, meet with UC Davis leadership, and provide guidance to Interim Director, Magali Billen during this period of transition. The EC found very strong support for CIG-IV from UC Davis and also from those members of the CIG community that we have talked with and who have approached us. Community feedback is very important to help in the transition from CIG-III to CIG-IV and we identified a number of opportunities to gather your ideas for this phase of CIG including a community wide survey that is available immediately and which we would ask everyone to complete and pass on to interested parties. We hope to finalise the results of the survey by August 15. Survey link: CIG IV Strategic Planning Survey The EC also outlined the steps to prepare for and write the CIG-IV proposal to NSF (due in summer 2021) which include the following The steps towards submitting the CIG-IV proposal include: 1. gathering community feedback in the summer of 2019, 2. establishing a proposal writing committee in the fall of 2019, 3. convening an all-hands meeting in the spring of 2020, and 4. developing the CIG-IV proposal in the fall of 2020 to spring 2021. The time-line for planning and writing the CIG-IV proposal is outlined below. This plan begins with a community survey (add link) to map out the shifting landscape of software and community development priorities. 1. Summer 2019: gather community feedback (members of CIG, NSF, UC Davis etc) 2. Fall 2019: establish proposal writing committee 3. Spring 2020: all-hands meeting (2-days) follow by proposal writing meeting 4. Summer 2020: call for white papers 5. Fall 2020-Spring 2021: proposal writing As always, if you wish to contact a member of the EC directly, you can do so and we will treat your feedback in confidence. On behalf of the EC, I would like to wish everyone a happy and productive (Northern) Summer and look forward to reading your responses to the survey.

Oceanic lithosphere is recycled into the mantle, while continental lithosphere remains mostly intact, buoyant enough to withstand recycling and therefore evolving slowly over geologic time. Because of this dichotomy, the lithosphere is globally heterogeneous. This heterogeneity is manifested in various forms, including rheological, structural and compositional stratification (both lateral and vertical) inherited from both the time of formation and recent tectonic processes. Deciphering the interaction of the lithosphere with the deeper convective mantle is important for the better understanding of lithosphere-mantle coupling processes and to reconcile models with natural observations. We aim to bring together diverse disciplines that focus on the composition, rheology and deformation of the lithosphere and upper mantle. Some key areas of interest are, but not limited to, lithospheric structure, rheology, morphology, deformation, as well as active and passive margins evolution and dynamics, and subduction processes.

However, interpretation of such images is hindered by the finite resolving power of tomography and by non-linear relations between elastic parameters and other quantities of interest, such as composition, density and temperature. These relationships are not only influenced by the material properties of single minerals, but also by changes of the phase assemblage as a function of pressure and temperature. Furthermore, the anelastic nature of minerals adds to the difficulty of interpreting seismic models, as the parameters controlling the associated increase in temperature sensitivity of the velocities are not well-constrained. This session provides a platform to present advances in constraining interpretations of seismic tomography. Of general interest are quantifications of uncertainties, tests of interpretations against independent datasets, theoretical results from geodynamic modelling and mineralogical studies constraining the relationship between temperature and seismic velocity.

Interactions between Magmatism, Tectonics, and Faulting in Rifts, Arcs, Ridges, Calderas, and Volcanic Fields View Session Details: https://agu.confex.com/agu/fm19/prelim.cgi/Session/72237 Abstract: Interactions between magmatism, tectonics, and faulting occur at different temporal and spatial scales, as they are observed from individual volcanoes to plate boundaries, during single eruptive events or over centuries. However, our current understanding is still limited due to a lack of integrated approaches. Field, geodetic, and modeling studies suggest that earthquakes can trigger volcanic eruptions and intrusions through static and dynamic stress transfer. Conversely, magmatic activity can generate earthquakes via stress changes in surrounding country rock. In rifting events, magmatic fluids can release tectonic stresses and also be influenced by pre-existing fracture zones. Finally, the combined effects of magmatic, gravitational, and tectonic stresses can trigger caldera and volcano flank collapse. We strongly encourage multidisciplinary studies integrating geodesy, structural geology, volcanology, geochemistry, seismology, stress analysis, and/or modeling (numerical and analogical) to decipher relationships between magmatic, tectonic, and faulting processes at different temporal and spatial scales.

Abstracts are due July 31. T003: Advances in Computational Geosciences 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.
