S003: Advances in understanding of tremor, slow slip and other slow earthquake phenomena
Session ID#: 14143
Slow earthquakes encompass a variety of behaviors including tectonic tremor, very low-frequency earthquakes, and aseismic slow slip events (SSEs). At times, these behaviors are coincident, while at other times they are observed separately. Slow earthquakes may increase stress loading on the seismogenic zone and hold clues to a more thorough understanding of regional seismic cycles. Studies have indicated slow earthquakes to be a potential precursor of megathrust earthquakes, but the necessary linkage remains unclear. Additionally, up-dip transitional zones showing evidence of slow earthquakes can rupture coseismically, producing larger tsunamis and earthquakes than previously expected. This session aims to provide an understanding of slow slip and associated seismic phenomena, and their possible connection to large damaging earthquakes. We welcome abstracts that cover seismological, geodetic, and geological observations, seismicity catalog statistics, laboratory experiments, and theoretical modeling.

T026: One Rift, Two Rift, Magma-Rich Rift, Magma-Poor Rift: Deformation, magmatism, volatile fluxes, and their consequences in the East African Rift SystemT041: The role of the forearc mantle in subduction zone processes
Session ID# 12985
The East African Rift system represents one of the largest active continental rift systems in the world, and it exhibits remarkable variability along its length in the amount and style of extension, seismicity, volcanism, volatile fluxes and surface morphology. As such, the EARS presents a natural laboratory for investigating the controls on continental extension from initiation to final breakup and consequences for hazards, microclimate and ecosystems. We invite abstracts from diverse fields (e.g., geochemistry, geodynamics, geology, geophysics) focused on elucidating the evolution of tectonic deformation, magmatism, and volatile fluxes during continental rifting in the EARS and comparative studies of other extensional systems elsewhere around the globe.

T035: Subduction Top to Bottom (ST2B-2)
Session ID#: 12903
From top-to-bottom, many geological, geophysical, petrologic/geochemical, and theoretical advances have been made toward understanding subduction zone processes and dynamics since AGU Geophysical Monograph “Subduction Top to Bottom” was published 20 years ago. This session and a related themed issue in GEOSPHERE are intended to revisit the issues that were explored in the 1996 publication and re-assess them in light of recent advancements as well as explore new discoveries and advances in subduction zone research. We invite the broadest possible range of contributions, including subduction-related hazards (volcanic eruptions, earthquakes and tsunamis) and resources.

T039: The Aleutian-Alaska Arc: Volcanic and Tectonic Processes
Session ID#: 12941
The Aleutian-Alaska arc has seen a recent explosion of research motivated by coordinated programs such as GeoPrisms, EarthScope and The Alaska Volcano Observatory. In this session we hope to bring together new observations and insights into the active tectonic and magmatic processes and evolution of the Aleutian-Alaska subduction zone, with comparisons to subduction zones world-wide. Especially encouraged are presentations that combine geological, geophysical and geochemical datasets, as well as geodynamic models and laboratory experiments spanning major portions of the subduction system – from the trench outer rise to the megathrust, from the plate coupling transition zone to the regions of fluid and melt production, and from the mantle to surface volcanism.

T041: The role of the forearc mantle in subduction zone processes
Session ID# 12515
The forearc mantle wedge forms at the onset of subduction. Upon dehydration of the downgoing plate, some parts of the forearc wedge become hydrated, forming serpentinites. Hydration of the forearc wedge is an important factor that affects subduction dynamics, for example, by influencing the strength and buoyancy of the wedge and volatile recycling. However, in spite of numerous efforts, the physical and chemical conditions in the forearc mantle wedge remain elusive. To what extent/depth is it serpentinized? How is it related to the sliding behavior of the plate interface? Is part of the wedge dragged down-dip with the slab? Does it play a role in the generation of arc magmas? Is it a source or a sink in the deep volatile cycle? This session seeks contributions from geophysical and geochemical studies, petrography, lab experiments and field observations that provide new insights into the evolution of the forearc mantle wedge.

DI009: Multidisciplinary constraints on the distribution of melt and volatiles and their roles through the subduction system
Session ID#: 12536
Subducting slabs transport geodynamically and geochemically significant quantities of volatiles to the Earth’s interior. A large portion of these materials returns to the surface/crust via volcanic arc and back-arc magmatism. The return flux involves processes from slab dehydration to hydration and melting of the mantle wedge to magma transport and eruption within the overriding plate. These processes are inherent to subduction zone dynamics and impact tectonic forces, and also critical for estimating Earth’s water budget. Recent datasets, both onshore and offshore, and improved modeling capabilities provide opportunities to study the transport of melts/fluids/volatiles through the subduction system. We welcome stimulating contributions from all subdisciplines – field observations, laboratory results, and modeling – seeking to harness complementary constraints from multiple data types and to foster interdisciplinary collaboration. We particularly welcome studies using amphibious datasets that show the scientific potential of bridging the land/sea barrier.

ED033: Sympathy for the Data: Novel approaches to the art of data visualization
Session ID# 13499
We would like to invite the community to consider submitting abstracts to our AGU 2016 Fall Meeting session, which focuses on novel data visualization techniques. Specifically, we would like to bring together a diverse range of geoscientists to discuss the many different platforms and technologies being used and developed for data visualization. It is listed in the Education section (and so doesn’t count towards the 1 submitted, 1 invited abstract limit for the AGU Fall Meeting), and is cross-listed with Public Affairs. This session is also being considered for alternate presentation formats.
Representing data in a clear, concise and attractive manner is the primary tool scientists use to communicate their research at all levels. Insights into complex systems within Earth sciences often arise through the integration of highly varied, multidimensional, and ever-growing datasets. However, concisely communicating results within traditional frameworks can be challenging. Developing clear, interactive and intuitive visualization software and pedagogy can aid scientists in sharing new and innovative research with their peers and the general public. We invite abstracts focused on best practices of data visualization in the Earth sciences as well as introducing new approaches and platforms. Abstracts will ideally center on data visualization across a breadth of subjects and the inter-disciplinary potential of methods/products. Although the primary focus of the session focuses on visual aids, alternative approaches (e.g. the use of sounds) to communicating data are encouraged.
Please consider contributing to what we hope is a beneficial discussion of the best data visualization techniques that we, as scientists, can continue to build on in the future to better communicate our research. We look forward to your contributions! Any questions can be addressed to Martin (martin@seismo.wustl.edu). We are very interested in receiving abstracts from a wide range of researchers to develop networks across disciplines.
