Invitation to judge GeoPRISMS student presentations at AGU


Dear GeoPRISMS Community,

The GeoPRISMS Office will again organize a best student presentation award at the AGU Fall Meeting, open to all students who work on GeoPRISMS- or MARGINS-related research. Students will compete for a best poster and best talk award both carrying a $500 cash prize. Awardees and runners up will be featured on the GeoPRISMS website and the Spring issue of the GeoPRISMS newsletter.

We hope that if you attend the AGU Fall Meeting this year that you will be able to help us evaluate the student presentations. We generally ask judges for their assessment of no more than three presentations. Please note that many of the student presenters will also be bringing their posters to the GeoPRISMS Townhall & Community Forum on Monday evening, so there will be an opportunity to participate as a judge even if you are not able to attend the student’s official session.

If you are able and willing to help judge the student presentations, please let us know by sending your availability at info@geoprisms.nineplanetsllc.com. We will contact you closer to the meeting with instructions and a selection of presentations that will take into account your expertise and time periods you are available.

* ExTerra: Evolution of arc crust

Sunday December 9, 2018 | 8:00am – 12:15pm | Kimpton Hotel Monaco, Athens Room

Conveners: Stacia Gordon (University of Nevada-Reno) and Alicia Cruz-Uribe (University of Maine)

Inspired by the success of convergent margin research funded through GeoPRISMS and discussions generated at ExTerra meetings, this workshop will gather together researchers with expertise in all aspects of the arc system on the Sunday preceding the AGU Fall Meeting in Washington, DC. The goal is to gather a broad group of geoscientists that use a variety of different approaches (field, experimental, petrological, geochemical, geochronological, seismic, numerical modeling) applied to different parts of the arc (the subducting plate, mantle, magma plumbing system, supracrustal rocks). The group will discuss what the major questions are that still surround the evolution of arc crust and what tools and methods will best answer these questions. The meeting will also serve to provide a space where early career researchers can network with more senior personnel, and where scientists from a variety of subdisciplines who work on different arc sections around the world can compare and contrast observations. In addition, this gathering of the  arc crust community will make a plan for future convergent margin research, specifically on arc crust. It is important to establish new goals and questions concerning arc crust before GeoPRISMS has fully ended to keep the momentum that this program established.

The format of the workshop will include a keynote lecture given by Oliver Jagoutz (MIT), followed by breakout groups on different areas of scientific interest within the broader arc system: 1) subduction/mantle influences, 2) plutonic plumbing system/magma storage, 3) volcanic components, and 4) supracrustal (metamorphic) components. One proposed outcome of the workshop will be for multiple groups to develop collaborative proposals to NSF EAR programs for research and field forums/institutes, which could then be leveraged for the submission of a larger proposal.

* Investigating subduction processes at the Hikurangi margin, New Zealand 

Sunday December 9, 2018 | 1:15pm – 5:30pm | Kimpton Hotel Monaco, Athens Room

Conveners: Laura Wallace (GNS Science, New Zealand, Univ. Texas Institute for Geophysics), Dan Bassett (GNS Science, New Zealand), Heather Savage (Lamont Doherty Earth Observatory, Columbia University), Samer Naif (Lamont Doherty Earth Observatory, Columbia University), Shuo Shuo Han (Univ. Texas Institute for Geophysics), and Patrick Fulton (Texas A&M University)

The Hikurangi margin offers an outstanding opportunity to address many of the key topics of GeoPRISMS Subduction Cycles and Deformation. Major international experiments to investigate subduction processes at the Hikurangi margin have taken place in the last year including two IODP drilling expeditions to investigate shallow slow slip events, and two seismic experiments with the R/V Langseth and R/V Tangaroa to investigate controls on plate coupling and slow slip. The objectives of a Hikurangi margin mini-workshop are to discuss new observations from the New Zealand focus site and their implications for an integrated understanding of subduction processes, as well as planning for upcoming experiments.

The first half of the miniworkshop will introduce the latest results from the recent GeoPRISMS-related research efforts at the Hikurangi margin (including IODP drilling and seismic experiments), and a discussion of the implications of these for GeoPRISMS SCD questions. The second half of the miniworkshop will consist of presentations on upcoming plans for field experiments and research at the Hikurangi focus site, and discussion on coordination of these efforts. We will also discuss any research gaps that might exist. In addition to a small number of overview talks on recent and future experiments, we will offer the opportunity for a limited number of short (~2 minutes) pop-up talks on synergistic activities at the Hikurangi subduction zone.

In addition to researchers focused on the Hikurangi margin, we welcome attendees interested in subduction deformation and megathrust processes in Cascadia and Alaska, to cross-fertilize ideas and research outcomes among all three of the GeoPRISMS primary sites. Student and early-career scientist participation is also encouraged.

Workshop on Community Projects in Volcanology


Summary: Two-day U.S. National Science Foundation supported workshop focused on interdisciplinary community volcano experiments

Purpose: Continued advancement in fundamental geoscience demands substantial and coordinated investment in new observational scales and integrative approaches. As a result, community projects with open-access data and software have seen increasing use among the U.S. National Science Foundation geoscience community. In parallel, recent community reports on volcanology and subduction zone processes (ERUPT, SZ4D, USGS) highlight many challenges and opportunities in volcano science that demand increased community coordination. However, volcano science has seen relatively limited use of the community project mechanism, making this inherently interdisciplinary field particularly well-poised for rapid advance if new initiatives are developed.

To address these aims this NSF-supported workshop will gather members of the broad volcanology community to identify the most pressing questions that are best addressed through community projects and explore the merits of different models for community projects. Discussion and synthesis of recommendations for community projects will span strategies for coordinated multidisciplinary observations, effective incorporation of education and training opportunities, and development of community frameworks to foster integrative volcanology research. The workshop will include plenary sessions to motivate and focus discussions, goal-oriented breakout group discussions, lightning talks, and poster presentations. As the specific agenda becomes available the workshop info website will be updated.

Opportunities for remote participation will include: 1) Submission of white papers prior to the workshop. The program committee will make the white papers openly available online and use them to help shape topics/goals for specific discussion session at the workshop. White paper submission will be through the registration website. 2) Web-based remote viewing of the plenary presentations and lightning talks at the workshop.

Dates: November 28-29 (full days) and 30 (half-day), 2018

Location: DoubleTree Hotel, Downtown Albuquerque, NM

Support: Travel support is available for about 50 U.S. participants. Applications for travel support are due by September 24th, 2018. Applicants will be notified of their travel support status by October 8th. Travel support will include up to $500 for air & ground transportation and up to 3 nights of accommodations at the hotel hosting the workshop.

V001. Accessorize it! Controls on the mobility of trace elements during subduction

Session ID: 52849

Conveners: Alicia Cruz-Uribe (University of Maine), Maureen Feineman (Penn State)

Session Description: Accessory phases of all types provide key tools for quantifying the trace element geochemistry, stable and radiogenic isotope geochemistry, geochronology, and phase equilibria of rocks in subduction zones. The mobility of traditional accessory phases such as zircon, rutile, titanite, monazite, allanite, and apatite, and perhaps of less studied accessory phases such as sulfides, halides, and oxides, provides a framework for interpreting trace element budgets and elemental fractionation in subduction zones, including volatiles and heat-producing elements. We invite contributions from all aspects of accessory phase geochemistry and petrology related to subduction, from the slab to the arc. We particularly invite studies linking one or more aspects of the subduction factory.

Confirmed Invited Speakers: Dustin Trail (Syracuse University)

MR003. Connecting Rheology, Microstructure, and Chemistry of the Upper Mantle: New Constraints from Experiments, Models, and Natural Observations

Session ID: 46785

Conveners: Yuval Boneh (Brown), Emily Chin (Scripps Institution of Oceanography, UC San Diego), Katharina Marquardt (Bayerisches Geoinstitut)

Session Description: Together, the rigid lithospheric lid and underlying weak asthenosphere comprise the Earth’s upper mantle. Several features, imaged geophysically and constrained from xenoliths/exhumed mantle sections, characterize the upper mantle. These include complex mantle kinematics (e.g., flow around subduction-zones), enigmatic discontinuities (mid-lithospheric and lithosphere-asthenosphere discontinuities), as well as the cratons stability paradox (long-lived stability with evidence for deformation). These phenomena can be explained through evolution in microstructure (e.g., grain-size, crystallographic preferred orientation), the chemical environment (e.g., water content, chemistry, and structure of grain-boundaries), and/or the existence of melt. In this session, we explore the effect of microstructure and chemistry and their relationships with the strength, deformation mechanisms and tectonic history of the upper mantle. We invite abstracts from a variety of scientific ventures, e.g., rock deformation experiments, analysis of natural samples, and numerical models, to shed light on the microstructural and chemical effect on upper mantle strength and tectonic evolution.

ED001. 3D Printing in Earth and Planetary Science Education and Outreach

Session ID: 48843

Conveners: Christodoulos Kyriakopoulos (University of California Riverside), Gary B. Glesener (Virginia Polytechnic Institute and State University)

Session Description: 3D printing is a cutting-edge technology that holds tremendous promise for scientific research and education. For Earth and planetary scientists, the advantages of using such technology includes the ability to elucidate spatially complex geological structures and processes that are otherwise difficult to visualize using 2D media such as computer screens or paper. Concepts around earthquake faults, volcanoes, and trilobites often become more approachable for non-experts when 3D printed because they can be handheld and sometimes physically manipulated. The generation of 3D printed models, including experimental Lab samples (e.g. synthetic rocks), is not only a way to create hands-on educational activities, but a powerful tool to present our data and numerical models to a broader audience. This session focuses on 3D printing techniques and examples of 3D printed models used to enhance educational experiences. Presentations that focus on 3D printing technology, pedagogy, or both are welcome.

DI009. Dynamic Connectors: How Boundary Layers Shape the Evolution of the Earth’s Deep Interior

Session ID: 52478

Conveners: Keely Anne O’Farrell (University of Kentucky), Tobias Rolf (University of Oslo), Mingming Li (Arizona State University)

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.

Confirmed invited speaker: Andy Biggin, University of Liverpool

T026. Linking Tectonic Geomorphology and Plate Boundary Processes in Terrestrial and Marine Environments

Session ID: 48541

Conveners: Jenna C Hill (USGS Pacific Coastal and Marine Science Center Santa Cruz), Janet Tilden Watt (USGS Pacific Coastal and Marine Science Center Santa Cruz), Daniel S Brothers (USGS Pacific Coastal and Marine Science Center Santa Cruz), Jared Kluesner (USGS Pacific Coastal and Marine Science Center Santa Cruz)

Session Description: Spatial variation in the crustal structure, kinematics, and seismogenic behavior of plate boundaries is often expressed in tectonic geomorphology and shallow structure both onshore and offshore. In this session, we aim to explore the relationship between surficial geomorphology, sediment dynamics and active tectonics to plate boundary processes, including studies that link upper plate processes to deeper crustal structure or hazards that are often associated with large earthquakes (e.g., landslides, tsunamis). We invite contributions from both marine and terrestrial environments, particularly those that employ new tools and advanced techniques for characterizing and quantifying spatial variability in deformation mode, rate, and recurrence. As it is particularly important to consider studies that span major geomorphic process domains (i.e. from the shoreline to the base of the slope), we encourage contributions from a wide range of geographic areas that employ a variety of methods to examine plate boundary processes and segmentation.

Invited Speakers: invited speakers include Dr. Olaf Zielke (KAUST) and Dr. Luca Malatesta (UCSC), with a range of expertise from earthquake seismology to coupled tectonic-surface processes and geomorphology.

T029. Multiscale imaging of plate boundary fault systems: integrating geophysical and geological data

Session ID: 50206

Conveners: Valerie Sahakian (University of Oregon), Maureen Walton (USGS), Anne Tréhu (Oregon State University), Estelle Chaussard (SUNY Buffalo)

Session Description: In the half century since the advent of the plate tectonics paradigm, we have gained remarkable insights into the underlying physics of plate boundary systems from substantial increases in observational data and modeling results. Moving forward, the integration of these data is essential for a holistic view of tectonic processes and the natural hazards posed by plate boundaries. We hope to attract new research from different fields to emphasize the importance of multiscale data integration, including geophysical studies of seismicity, geodetic observations, source inversions, structural models, and numerical modeling, as well as geologic studies of surface processes, geochemical and laboratory analyses, and paleoseismic observations. We especially encourage multidisciplinary contributions that emphasize multiscale data integration, but also welcome focused studies of observations, methodologies, and/or modeling that aim to improve our understanding of plate boundary systems from the Earth’s surface through the lithosphere, and their relevance to natural hazards and society.

Invited speakers: Tim Wright (University of Leeds), Dan Bassett (GNS Science)

T031. Observations and models of multiphase deformation in rifts and rifted margins

Session ID: 45394

Conveners: John Naliboff, Rebecca Bell, Scott Bennett, Jolante van Wijk

Session Description: Observations from rifts and rifted margins suggest continental extension commonly involves multiple phases of deformation with distinct structural, sedimentary and magmatic characteristics. 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.

Invited Speakers: Donna Shillington (Columbia University), Robert Gawthorpe (University of Bergen)

T034. Puzzling Tectonics of the Gulf of Mexico: what do we know, what do we think we know, and what do we need to know?

Session ID: 49958

Conveners: Irina Filina (ifilina2@unl.edu), Erin K Beutel (beutele@cofc.edu), Patricia Persaud (ppersaud@lsu.edu) and Robert J Stern (rjstern@utdallas.edu)

Session Description: The tectonic history of the Gulf of Mexico is still being debated despite more than a century of petroleum exploration and an enormous amount of geophysical and geological data collected by industry. Tectonic models of the basin differ dramatically in key questions, such as the timing of opening, pre-breakup configuration of the crustal blocks and age of the seafloor. The proposed session intends to bring together researchers from different geoscience disciplines – geology, geophysics, geochemistry, tectonics, geodynamics – to discuss ways of improving our understanding of the basin. We welcome presentations on a broad range of topics – from addressing the continental break-up signature to those constraining sedimentation and hydrocarbon evolution. We also anticipate triggering active discussions on various aspects of Gulf of Mexico tectonics.

T041. Subduction Top to Bottom-2

Session ID: 43732

Conveners: David William Scholl (University of Alaska Fairbanks), Gray E Bebout (Lehigh University), Laura M Wallace (University of Texas at Austin)

Session Description: From top-to-bottom, many geological, geophysical, petrologic, geochemical and theoretical advances have been made in understanding the subduction zone processes and dynamics explored in 1996 in AGU Geophysical Monograph 96, “Subduction Top to Bottom”. This session, and a related Themed Issue in the online journal GEOSPHERE, are intended to revisit the topics explored 22 years ago in Monograph 96—reassessing them in light of new advances and discoveries in subduction zone research. We invite the broadest possible thematic range of contributions, including subduction-related hazards (volcanic eruptions, earthquakes and tsunamis) and resources.

T042. Subduction zone processes at the Hikurangi margin, New Zealand

Session ID: 44155

Conveners: Laura M Wallace (GNS Science, University of Texas Institute for Geophysics), Rebecca E Bell (Imperial College London), Kimihiro Mochizuki (University of Tokyo), Demian M Saffer (Pennsylvania State University)

Session Description: The Hikurangi subduction zone offshore New Zealand’s North Island exhibits pronounced along-strike changes in margin characteristics that make it an outstanding natural laboratory to investigate a wide range of fundamental subduction processes. This unique aspect of the subduction zone has sparked a plethora of new onshore and offshore geological and geophysical investigations. These experiments are helping to unravel the physical processes that control subduction plate boundary geodynamics and deformation.  Recent efforts include scientific ocean drilling, multiple active and passive seismic experiments, seafloor geodetic deployments, and paleoseismic investigations.  We welcome submissions that advance understanding of the Hikurangi subduction zone, including processes that underlie slow slip events and earthquake cycle behavior, volcanism and intra-arc rifting, volatile and fluid cycling, long-term subduction margin evolution, and geohazards associated with the plate boundary. Modeling studies, and comparative studies with other subduction zones to elucidate factors controlling subduction zone processes are also very welcome.

T043. Subduction Zone Processes, Orogenesis and Seismic Hazard: From the Alpine-Mediterranean to the Indo-Burma Region

Session ID: 47151

Conveners: Patricia Persaud (Louisiana State University), Francesca Di Luccio (INGV, Rome), Claudia Piromallo (INGV, Rome), Michael S Steckler (LDEO, Columbia University)

Session Description:  This session aims to promote stimulating discussions on subduction zones and orogens and the evaluation of seismic hazard in these regions. The Alpine-Himalayan belt is characterized by several spatially limited, complex, highly heterogeneous and constantly evolving subduction zones in the Mediterranean. To the east, the structure and dynamics of the Indo-Burma subduction zone is quite poorly known. Revealing the dynamics of subduction systems along the Alpine-Himalayan orogenic belt is relevant to seismic hazard research due to the high population densities of these regions. We encourage authors to present novel data and innovative research based on multidisciplinary approaches. Research areas may include seismic imaging, surface and mantle processes, laboratory experiments and geodynamic modeling. We particularly encourage submissions that range from local to global scales, addressing any aspect of subduction-related and orogenic processes and their implications in subduction zones worldwide.

Invited Speakers: Anne Replumaz (Université Grenoble-Alpes), Eric Sandvol (University of Missouri)

Submissions from early-career scientists are strongly encouraged.

T044. Synthesis: Knowns and Unknowns of the Cascadia Subduction Zone

Session ID: 47390

Conveners: Helen Janiszewski (DTM, Carnegie Institution for Science), Wenyuan Fan (WHOI), Ikuko Wada (University of Minnesota), Caroline Seyler (McGill University)

Session Description: The Cascadia subduction zone is a global end-member warm-slab subduction zone and exhibits along-strike variations in subduction parameters (e.g., incoming plate age) and mechanical behavior (e.g., seismogenesis), serving as a unique natural laboratory to investigate a range of subduction zone processes, including tsunamigenic megathrust earthquakes, episodic tremor and slip, and arc volcanism. 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. We invite contributions from a wide range of disciplines, including (paleo)seismology, earthquake mechanics, geodesy, magnetotellurics, geochemistry, petrology, volcanology, structural geology, rock mechanics, and geodynamics.

Invited Speakers: Anne Pommier (UCSD), Amy Williamson (University of Oregon)

T051. The Varied Roles of Aqueous Fluids Near the Subduction Interface

Session ID: 47101

Conveners: Cailey B. Condit (MIT), Besim Dragovic (Boise State), Jonathan R. Delph (Rice University), Melodie E. French (Rice University)

Session Description: Along the subduction plate interface, water influences the rheological and geophysical properties as well as the rates and products of metamorphic reactions. Recent geologic and seismic studies demonstrate that strong feedbacks exist between the fluid-mediated chemical and petrologic evolution of the rock, deformation processes that control fault slip behavior, and geophysical signals we use to interpret physical conditions at depth. Fluid distribution and flux are thought to vary with depth and the permeability structure near the plate interface. These fluids are proposed to control episodic tremor-and-slip, dehydration-induced seismicity, serpentinization of the mantle wedge, overriding plate alteration, and the 4-D evolution in interface bulk-rock compositions, active deformation mechanisms, and rock strength. We invite contributions addressing the varied influence of aqueous fluids near the subduction interface from across the Earth science community including, but not limited to: experimental studies, geodynamics, petrology/geochemistry, structural geology, and geophysics.

Invited speakers: Roland Burgmann (UC-Berkeley) and Emily Cooperdock (WHOI)

T054. Whose Fault Is It? Relating Structural and Compositional Heterogeneity to Slip Behavior

Session ID: 49102

Conveners: Hannah Rabinowitz (Brown University), Helen Janiszewski (DTM), Samer Naif (LDEO), Ake Fagereng (Cardiff University)

Session Description: Large plate boundary fault systems are commonly rheologically segmented both along strike and down dip, including across the transition from seismic to aseismic shear displacement. In addition to thermal controls, these variations in slip style may arise due to geometric or compositional heterogeneities along the fault zone. Many questions remain on the relationships between structure and fault behavior. For example, how does rupture propagation interact with roughness or material properties along a fault at a range of slip rates? How does this impact the global variability in seismic behavior at plate boundaries? In this session, we will highlight recent advances in characterizing observed structures, geophysical properties, lithologies, and slip behaviors at plate boundary faults at a range of scales, with a focus on relationships between these features. We encourage submissions from seismology, magnetotellurics, geodesy, earthquake rupture modeling, structural geology, fault zone drilling, and experimental work.

Invited Speakers: Thomas Goebel, TBA

S032. The Role of Slow Slip Events in the Earthquake Cycle: Stressing, Triggering, and Hazard

Session ID: 53250

Conveners: Bill Fry (GNS Science), Matt Gerstenberger (GNS Science-Institute of Geological and Nuclear Sciences Ltd), Yoshihiro Kaneko (GNS Science)

Session Description: Several recent great and large earthquakes have been correlated with slow slip events (SSE) on plate boundaries. Events in Japan, Chile, and New Zealand have preceded or triggered SSE. However, the physical interaction between fast and slow earthquakes is currenty poorly understood and many questions exist, including the relation of SSE to future large earthquakes. Understanding this interaction, either from a physical or statistical perspective, is crucial to explaining where and when future large earthquakes may occur.

Ongoing research aims to understand and model the occurrence of SSE. However, scant research specifically focuses on the role of SSE in triggering fast earthquakes. We invite contributions which investigate if and how SSE can trigger large earthquakes using such methods as physics based modeling (e.g., Rate and State Friction, seismicity simulators, stress modeling, etc.), empirical modeling or observations (e.g., ETAS, rate changes, etc.), paleoseismology or any study providing insight into this problem.

OS018. Geologic Evolution of Continental Shelves

Session ID: 48962

Conveners: Shannon Klotsko (San Diego State University), Ashley McCleaf Long (Coastal Carolina University), Jillian Maloney, San Diego State University, Jenna Hill, USGS, Pacific Coastal and Marine Science Center

Session Description: The geologic evolution of continental shelves is linked to large-scale driving mechanisms including tectonics, climate, and sea level variations. On shorter timescales, processes that shape continental shelves include sediment dynamics associated with waves, tides and currents, as well as biologic activity and submarine groundwater discharge. These processes operate across various spatial and temporal scales, adding complexity to interpretations linking processes to morphology. Furthermore, continental shelves cycle between subaerial exposure and submergence associated with sea level fluctuations that repeatedly reshape the shelf and render the shoreline an artificial boundary in landscape evolution. We encourage submissions from onshore and offshore studies that investigate a broad range of topics including fluvial drainage history, sediment dynamics, paleoshorelines, drowned landscapes, shelf morphology and geologic framework controls on benthic habitats from both passive and active continental shelves worldwide. We welcome contributions from field observations including geophysical surveys, outcrop and core studies, landscape modeling, and laboratory experiments.

Invited speakers: Jennifer Miselis, USGS, #2 pending
