From rene.gassmoeller at mailbox.org Fri Jul 6 16:06:56 2018 From: rene.gassmoeller at mailbox.org (Rene Gassmoeller) Date: Fri, 6 Jul 2018 16:06:56 -0700 Subject: [CIG-ALL] ASPECT 2.0.1 released In-Reply-To: References: Message-ID: <6cce92f5-a79b-6628-502c-efc101592138@mailbox.org> We are pleased to announce the release of ASPECT 2.0.1. ASPECT is the Advanced Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from                    https://aspect.geodynamics.org/ and the release is available from         https://github.com/geodynamics/aspect/releases/tag/v2.0.1 This release is a bugfix release for 2.0.0 and includes the following fixes: - Fixed: The 'compositional heating' heating plugin had a parameter   'Use compositional field for heat production averaging' that was used   inconsistently with its description. Its first entry did not correspond   to the background field, but to the first compositional field, and the   last value was ignored. This is fixed now, the first entry is used for   the background field, and all following values determine whether to include   the corresponding compositional fields. - Fixed: The 'depth dependent' material model did not properly initialize   the material model it uses as a base model. This caused crashes if the   base model requires an initialization (such as the 'steinberger' material   model). This is fixed now by properly initializing the base model. - Fixed: The advection assembler for DG elements was not thread-safe,   which led to wrong results or crashes if a discontinuous temperature   or composition discretization was combined with multithreading. - Disabled: The particle functionality was not tested when combined with a   free surface boundary, and this combination is currently not supported. This   limitation is now made clear by failing for such setups with a descriptive   error message.

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:Chris Rollins, University of Alaska Fairbanks Adriano Gualandi, NASA Jet Propulsion Laboratory/CaltechMong-Han Huang, University of Maryland Feel free to send any questions or comments to me at jrollins2 at alaska.edu or to any of the co-conveners, and we hope to see you there!

As these processes pose natural hazards, understanding their underlying causes is critical to natural hazard mitigation. The recent influx of offshore and onshore geophysical, geochemical, and geological data provides new opportunities to evaluate the entire Cascadia subduction zone in a coherent and consistent manner at various length and time scales. This session aims to synthesize recent findings and outstanding questions about this subduction system and the processes that occur within.

In many rifts, deformation evolves both as a function of time and location, and rift architecture may reflect the influence of structural inheritance, evolution of the lithosphere’s thermal-mechanical profile, feedbacks between surface process and lithospheric deformation or large-scale changes in plate driving forces. Here, we solicit presentations that examine the long-term evolution of continental rift systems through field, geophysical and numerical investigations. In particular, we encourage submissions that focus on the processes driving changes in deformation style and use large 3-D observational or numerical data sets to characterize lithospheric deformation.

Sincerely, Shi Joyce Sim (Carnegie/DTM) Rene Gassmoller (UC Davis) Adina Pusok (Scripps Institution of Oceanography) DI023: Towards success in geodynamic modeling - Learning from and improving on model iterations Numerical and analog models form a crucial part of our theoretical understanding of the Earth and they typically require careful implementation to be successful. Published model results rarely mention the attempts that were unsuccessful, therefore, burying the important conclusions that could be drawn from these 'failed' models, or lessons that could be learned about how to 'fail' best. This is particularly true for geodynamic modeling, where the combination of assumptions, complex methods, and complicated results makes the creation of an informative model a tedious task. We invite contributions (pertaining but not limited to core, mantle, lithosphere and planetary dynamics) of unexpected, controversial, failed and/or negative model results. In particular, we encourage (1) conclusions from unexpected results, (2) the critical mindset when evaluating models, (3) best practices to ensure reliability and reproducibility, (4) the inherent limitations of models, and (5) strategies to cope with repeated disappointments of unsuccessful models. -- Rene Gassmoeller https://gassmoeller.github.io/ -------------- next part -------------- An HTML attachment was scrubbed...

Cheers, Keely O’Farrell, Tobias Rolf and Mingming Li Session Title: Dynamic Connectors: How Boundary Layers Shape the Evolution of the Earth's Deep Interior Session Description: Mantle dynamics at different scales are influenced by boundary layer processes. The upper boundary affects subduction processes and driving of plate tectonics. The bottom boundary controls plume generation and is dynamically linked to deep thermochemical features, such as LLSVPs and ULVZs. Plumes rising from the bottom boundary layer sample the whole mantle and place their signature on Earth's surface, providing insight into mixing of chemical heterogeneities and the state of the deep mantle. The two boundary layers connect Earth's surface, core and mantle interior and govern their interaction. Understanding the dynamics in the boundary layers will help to link shallow and deep mantle processes.This session will explore the dynamics of boundary layers, including generation of subduction zones, plate tectonics, mantle plumes, and heat transfer, and the resultant surface observations that provide useful constraints. We welcome theoretical, experimental, and observational contributions from geodynamics, seismology, geomagnetism, mineral physics, petrology, and other disciplines.

Welcome to submit an abstract! Thanks for your attention, Lijun Dear colleagues, Please consider submitting an abstract to our session entitled: DI004: A multi-disciplinary View of Mantle Heterogeneity: Linking Earth’s Chemical, Physical, and Dynamical Evolution The deadline for all submissions is Wednesday, 1 August 23:59 EDT. Advances in geophysical modeling of Earth's mantle reveal in increasing detail its heterogeneous, three-dimensional structure. Mineral physics allows this heterogeneous structure to be interpreted in terms of compositional or thermal anomalies that deviate from an ambient mantle. Geochemical analyses of mantle-derived samples provide additional evidence for a compositionally heterogeneous mantle and, in some cases, its temporal history. The heterogeneous nature of the mantle as characterized by these disparate (yet inter-related) datasets is ultimately controlled by the dynamical evolution of our planet, however, details surrounding the nature of these heterogeneities remain debated. This session will explore mantle heterogeneities in a multi-disciplinary perspective from the uppermost mantle to the core-mantle-boundary. This includes observational, experimental, theoretical, and numerical approaches that investigate links between the physics and chemistry of Earth's interior. We also encourage abstracts that use novel data collection and visualization techniques to further understand the structure and dynamics of Earth's mantle.

Its birth and demise act as the major driving force of plate motion, and a key mechanism of the water and carbon cycle throughout the planet earth. Understanding the interaction of the lithosphere with the underlying asthenosphere and the deep mantle is critical to understanding the secular evolution of the earth system, and requires knowledge of the compositional, elastic/anelastic, and thermal structures of the lithosphere. We welcome contributions from geophysics, geodynamics, and petrology/mineralogy that help to build a unified view on the dynamical evolution of the lithosphere. Example topics include, but are certainly not limited to variations in lithospheric properties as a function of tectonics and dynamics, lithospheric structure of the oceans or continents, and lithosphere recycling and its dynamic implications.

Rob, Harriet, Bernhard and Siobhan ------------------------------------------------- Session Title: DI020: The Influence of Mantle Dynamics on the Earth System https://agu.confex.com/agu/fm18/prelim.cgi/Session/50740 Session Description: Mantle convection drives processes like mountain building, earthquakes, the origin and eruption of large igneous provinces, hotspot-related volcanism, and dynamic topography. Interdisciplinary efforts consider mantle dynamics a key influence in landscape evolution, sea-level and ice-volume changes, and, through volcanism and subduction, the source and sink for important volatiles. These examples demonstrate the mantle’s role in Earth’s long-term climate. Surface manifestations of mantle dynamics not only provide constraints on subsurface structure but also valuable insight into the broader Earth system. This expansive session explores interdisciplinary approaches that use surface observations to capture this dynamic mantle-surface-atmosphere system. Questions addressed could include: Has the style of mantle convection changed through time and is this reflected in the rock record? Can novel surface observations offer new constraints on mantle properties? What is the influence of mantle convection on key events throughout Earth’s history? We encourage critical assessments of uncertainties in both modeling and observations.

Abstracts can be submitted to this session here: https://agu.confex.com/agu/fm18/prelim.cgi/Session/52511 Session Description: DI003: Advances in Understanding Earth's Dynamic Processes Using Seismic Anisotropy "Understanding the process and evolution of mantle dynamics represents a fundamental goal of Earth science. However, it has also posed a major challenge due to the inaccessible nature of the solid Earth and uncertainties in observation and modeling. Recent advances in measuring seismic anisotropy have generated new constraints on the deformation of the Earth's interior associated with subduction zone processes, lithosphere deformation, mantle circulation, the core-mantle boundary, and growth of the inner core. In addition, novel modeling techniques now enable the simulation of dynamic processes in the Earth at unprecedented levels of resolution and physics. As a result of these combined efforts, new perspectives are emerging on the evolution of the crust, lithosphere, mantle, and core. We invite submissions on the deformation and structure of the solid Earth from seismic and MT measurements, laboratory simulation of fabrics and plastic deformation of crystals, theoretical calculations, and geodynamic modeling."
