About the program
The University of Minnesota College of Science and Engineering (CSE) is pleased to announce its commitment to a new CSE-President’s Postdoctoral Fellowship Program (CSE-PPFP). The program is a partnership with the University of Minnesota’s Institute for Diversity, Equity, and Advocacy (IDEA) that aims to make CSE more diverse, equitable, and inclusive.

Building a more diverse community
The CSE program builds from the existing University of Minnesota President’s Postdoctoral Fellowship Program (UMN PPFP). The program seeks applicants whose research, teaching, and service will contribute to the University of Minnesota’s Office of Equity and Diversity’s mission, vision and values.
While the UMN PPFP defines diversity broadly, the emphasis of the CSE-PPFP partnership will be on Black, Indigenous, and People of Color (BIPOC) candidates, and we strongly encourage such applicants.

Program starts in fall 2021
Three Fellows will be recruited for fall 2021 and three additional Fellows will be recruited for fall 2022 to create a steady-state cohort of six Fellows, based on a two-year position for each Fellow. The college will support a CSE-PPFP Community where Fellows engage with each other, access faculty mentoring from diverse perspectives, network with industry and alumni, and emerge as strong candidates for tenure track positions at the University of Minnesota.

We look forward to welcoming our first cohort of CSE-PPFP Fellows in 2021!

Session Title: Advances in Understanding Continental Margin Evolution: Two Decades of GeoPRISMS and MARGINS Science

Section: Tectonophysics

Over the past two decades, the GeoPRISMS and MARGINS programs have brought together a vibrant community of geoscientists to conduct computational, laboratory, and large scale field experiments that span the shorelines of continental margins. These interdisciplinary investigations aim to understand Earth’s most active tectonic, mass transfer, and sedimentary systems, and have yielded new insights into processes that underlie both active and passive margin evolution, and major geohazards that affect population centers, including large earthquakes, volcanic eruptions, tsunamis, and landslides. In this session, we invite presentations that contribute to advancing and integrating the research efforts of these two decadal programs and their associated communities, including research at focus/primary sites, allied thematic studies, and particularly work that uses large and diverse datasets to synthesize geophysical, geochemical, numerical, and/or experimental investigations to illuminate and quantify fundamental processes that control deformation and mass flux at active subduction zones, continental rift systems, and passive margins.

T032 | Where is the melt during the evolution of continental rifting?

https://agu.confex.com/agu/fm20/prelim.cgi/Session/101051

Conveners: D. Sarah Stamps (Virginia Tech), Emmanuel Njinju (Virginia Tech), Micah Mayle (Colorado State University), Dennis Lee Harry (Colorado State University)

Abstract: Continental rupture requires weakening mechanisms to overcome lithospheric strength. Magma is one factor that can play a critical role in accommodating strain partitioning during continental rifting. Ample evidence supports that melt weakens the lithosphere in magma-rich rift systems, such as in Iceland and the Main Ethiopian Rift in East Africa. In addition, the potential role of deep crustal and/or mantle melt in magma-poor rifts may also be important. Geochemical, seismic, magnetotelluric, and gravity data have shed some light on the locations of magma at depth in continental rifts, and geodynamic modeling helps isolate the distribution of melt. In this session, we welcome submissions focused on advancing our understanding of the role of, causes of, and locations of melt at depth during continental rifting. Both evidence-based and geodynamic modeling studies are encouraged that may address continental rifting at any phase of development.

V001 | A Multidisciplinary Approach to Investigating Crustal Processes

https://agu.confex.com/agu/fm20/prelim.cgi/Session/103929

Conveners: Wentao Cao (SUNY Fredonia), Silvio Ferrero (University of Potsdam), Chris Yakymchuk (University of Waterloo)

Abstract: The Earth’s crust is a dynamic place where essential geological processes (e.g. magmatism, metamorphism, and metasomatism) occur. Examining igneous and metamorphic rock records is key to improving our understanding of the crust, from its chemical compositions, geochemical characteristics, and structural properties to the geochemical differentiation and tectonic evolution of the Earth’s lithosphere from the Archean to the present. Various techniques, including geochemical, geochronological, experimental and modeling methods can be applied to investigate composition, conditions, processes, timing, timescale and rate of crustal processes. This session welcomes contributions that advance our understanding of crustal processes in all aspects. Related research includes but not limited to formation and evolution of continental crust, petrological, geochemical and geochronological investigations of crustal materials, experimental studies of crustal materials, phase equilibrium modeling of crustal processes, and geodynamic modeling.

V021 | SZ4D: How Do Processes Within Transcrustal Magma Systems Initiate Eruptions at Arc Volcanoes?

https://agu.confex.com/agu/fm20/prelim.cgi/Session/105911

Conveners: Adam J R Kent (Oregon State University), Claire E Bucholz (California Institute of Technology), Patricia M Gregg (University of Illinois at Urbana-Champaign), Eric Kiser ( University of Arizona)

Abstract: Understanding the processes that lead to initiation of volcanic eruptions at arc volcanoes lies at the frontier of subduction zone science. In this session we seek contributions from geology, geochemistry, petrology, geodesy, seismology, numerical modeling and other disciplines that investigate processes that promote the initiation of volcanic eruptions and provide a greater understanding of the complex transcrustal-scale magma plumbing systems that feed these events.

This session is organized by the Magmatic Drivers of Eruption (MDE) working group of the Subduction Zones in Four Dimensions (SZ4D) Research Coordination Network. This is an initiative to propose a new program to study subduction zones – the places where tectonic plates converge and collide – through both space and time, with a focus on the fundamental processes underlying geologic hazards such as great earthquakes, tsunamis, landslides, and volcanic eruptions.

Note that part of this session will be held as a discussion panel, but we are also soliciting abstracts for additional sessions.

MR004 | Elasticity: Connecting the Properties of Minerals to Planetary Models

https://agu.confex.com/agu/fm20/prelim.cgi/Session/105894

Conveners: Elizabeth Thompson (Sewanee: The University of the South), Renata Wentzcovitch (Columbia University), Jung-Fu Lin (University of Texas at Austin), Han Hsu (National Central University of Taiwan)

Abstract: In order to understand the structure and composition of the Earth and its moon, we rely on our understanding of the elastic properties of potential constituent materials to inform interpretations of seismic velocities and geodynamical models. More recently, elastic constraints have also become invaluable in our efforts to better understand the structure and composition of Mars. This session aims to bring together computational and experimental researchers who determine the elastic properties of geological materials and melts with the researchers who employ these constraints to interpret tomographic models and those who develop novel geodynamical models of planetary bodies.

DI002 | A Multidisciplinary Approach to Understanding Volatiles in Earth’s Mantle

https://agu.confex.com/agu/fm20/prelim.cgi/Session/101837

Conveners: Dan Rasmussen (Smithsonian NMNH), Doug Wiens (Washington University), Megan Duncan (Virginia Tech), and Cara Vennari (University of Chicago)

Volatiles are fundamental to the physical, chemical, and biological evolution of the Earth. The mantle is a large reservoir for volatiles and plays an important role in volatile cycling between Earth systems. Even at low concentrations, such storage exerts key controls over the physical properties of the mantle that shape the geodynamic processes. Despite their importance, volatile contents in and fluxes in and out the mantle remain poorly constrained. Our knowledge of the volatile content and movement in the mantle stems from both direct and indirect observations of volatiles in igneous and metamorphic rocks, high pressure and temperature experiments and simulations, numerical models of mantle convection, and seismic observations. This session aims to bring together interested parties that draw observations from the surface with those who study the system at depth. We invite contributions multiple disciplines including, volcanology, geochemistry, mineral physics, seismology, and geodynamics.

Invited Presenters: Wendy Panero (Ohio State University) and Krister S. Karlsen (University of Oslo)

Over the past two decades, the GeoPRISMS and MARGINS programs have brought together a vibrant community of geoscientists to conduct computational, laboratory, and large scale field experiments that span the shorelines of continental margins. These interdisciplinary investigations aim to understand Earth’s most active tectonic, mass transfer, and sedimentary systems, and have yielded new insights into processes that underlie both active and passive margin evolution, and major geohazards that affect population centers, including large earthquakes, volcanic eruptions, tsunamis, and landslides. In this session, we invite presentations that contribute to advancing and integrating the research efforts of these two decadal programs and their associated communities, including research at focus/primary sites, allied thematic studies, and particularly work that uses large and diverse datasets to synthesize geophysical, geochemical, numerical, and/or experimental investigations to illuminate and quantify fundamental processes that control deformation and mass flux at active subduction zones, continental rift systems, and passive margins.

Please see below for sessions of interest to the GeoPRISMS Community, taking place at the 2020 AGU Fall Meeting, December 7-11. Note that AGU Fall Meeting will be mostly virtual.

AGU abstract submission is now open until July 29.

T011 | From trench to back-arc: Dynamics of the Hikurangi subduction zone

https://agu.confex.com/agu/fm20/prelim.cgi/Session/102769

The Hikurangi subduction zone off New Zealand’s North Island exhibits intriguing variations in volcanic, tectonic, and megathrust slip processes making it an outstanding natural laboratory to probe these processes. With support from NSF, IODP, GeoPRISMS, and numerous New Zealand and international agencies, many geophysical, geological, and geochemical studies have recently been carried out to investigate the interplay of these variations, especially as they relate to plate boundary tectonics and the diverse controls on volcanism. We welcome submissions that improve our understanding of the Hikurangi subduction system, including the role of fluids, volatiles, and sediments in subduction and volcanic processes, factors controlling megathrust earthquakes and slow slip events, offshore gas hydrates and slope instability, the generation and transport of magma, and comparative studies from other subduction margins. We encourage a diversity of methods for addressing these topics, such as electromagnetism, seismology, geodesy, gravity, numerical modeling, scientific drilling, petrology, and structural geology.

T012 | Geophysical, Mechanical, and Geologic Constraints on the Subduction Interface

https://agu.confex.com/agu/fm20/prelim.cgi/Session/104013

Conveners: Helen A Janiszewski (University of Hawaii at Manoa), Cailey Brown Condit (University of Washington), Noel M Bartlow (University of California Berkeley), Melodie E French (Rice University)

Our understanding of subduction interface slip behavior and structure comes from integration of geophysical imaging, experimental studies, and observations from the rock record. The rheology and structure of the plate interface are essential components influencing slip behavior of the subduction plate boundary. Interpretation of geophysical observations at these zones is inherently dependent on fundamental rock properties; likewise understanding of the deformation of these materials depends on experimental and geologic studies, and numerical modeling. In this session, we aim to engage an interdisciplinary research community, drawing from seismology, magnetotellurics, rock mechanics, geodesy, and geology, focused on constraining the structure and slip properties along the subduction plate interface. Work extending from the trench, across the seismogenic zone to the locations of deep episodic tremor and slip are encouraged. We will highlight research results from the past decade of GeoPRISMS focus sites, Cascadia, Alaska/Aleutians, and Hikurangi, but welcome submissions outside of these areas.
