<![CDATA[EAS Seminar Series - Dr. Rachel Abercrombie]]>36678 Small earthquakes contain a wealth of information about active structures, and the state of stress in the earth, not least because they are so numerous. The stress release (or stress drop) during an earthquake provides fundamental information about the energy budget, and the slip and area of rupture, which are needed to investigate earthquake triggering and rupture dynamics. Stress drop is also an important element of seismic hazard forecasting since high stress drop earthquakes radiate more high frequency energy, resulting in stronger ground shaking. However, in practice stress drop has proved notoriously hard to measure reliably. Estimates by different researchers, using different methods or datasets, have yielded highly inconsistent values. This wide scatter masks physical trends (such as depth, mechanism, regional variation, or dependence on fault heterogeneity) that may identify the factors governing earthquake rupture.
I will discuss recent work by myself and others focused on improving stress drop estimates, and investigating the uncertainties resulting from modelling assumptions and the ambiguity of separating source and path effects in recorded seismograms. A consistent observation is that there is more small-scale spatial variability and complexity within one individual sequence, than there is between earthquakes in different tectonic settings.

We examine whether this repeated transition may have been facilitated by plastic responses to the environment that were later stabilized by developmental-genetic changes. We use the volvocine green algae as a model system as this clade contains undifferentiated multicellular species, species with environmentally induced somatic differentiation, species with undifferentiated cells and developmentally regulated somatic cells, and species with germ-soma division of labor. We examine a multicellular volvocine algae species, Eudorina, which has been historically characterized as undifferentiated but can develop a small proportion of plastic somatic cells following exposure to cold shock. We exposed Eudorina cultures to repeated cold shock and characterized the differentiation status of our lines more than 30 generations after the cessation of the cold treatment. Somatic differentiation evolved rapidly, with most lines showing changes in the regulation of somatic cell development and several lines evolving obligate somatic cells. The increase in the proportion of colonies that were differentiated was correlated with an increase in the number of somatic cells per differentiated colony. The repeated evolution of differentiation was shaped by the selection imposed by cold shock, as differentiated colonies were more likely to survive cold shock. Moreover, genome sequencing revealed that the regulation of multiple genes associated with the response to cold stress were altered and the cold stress pathway was likely decoupled from environmental triggers. Taken together, our results demonstrate that selection can rapidly drive the repeated transition to differentiated multicellularity via the modification of plastic responses to the environment.

Solar storms pose radiation hazards to spacecraft and astronauts, upper atmospheric anomalies introduce drag that can prematurely de-orbit satellites, and disturbances in the ionospheric plasma distort or block communications and GPS signals. We are moving in the direction that space weather may someday be discussed in the same manner that severe weather is today.
Come and learn about a distributed CubeSat constellation concept that Georgia Tech is developing to map space weather effects on the ionosphere and their impacts on space-enabled technologies using natural signals of opportunity from lightning. This workshop will feature speakers from multiple GTRI laboratories and GT schools discussing the technologies and capabilities that Georgia Tech has available to provide important ionospheric measurements for “space weather meteorologists” that will also enable future improvements in forecast models.

Become a fossil hunter and help discover how vertebrate communities have changed through time. Experience firsthand what it is like to be a paleontologist, finding and identifying new specimens!
You will be picking and sorting 3,000 to 30,000-year-old fossil specimens from rock matrix that has been brought back from Natural Trap Cave, WY. These specimens are part of many research projects examining how the community of species living around Natural Trap Cave has changed since the extinction of the cheetahs, lions, dire wolves, mammoths, camels, horses, and other megafauna that used to live in North America.
You are welcome to participate anytime that is convenient, with no commitment necessary. In fact, you can drop in or leave anytime within the two-hour timeframe. All are welcome, so bring your friends!
If you are accompanying a minor (under 18), please be sure that a guardian/chaperone is with them at all times and that there is no less than one adult for every two minors.
For more information join the mailing list and/or contact Katie Slenker (kslenker3@gatech.edu) or Jenny McGuire (jmcguire@gatech.edu).
* No T. rex actually helped with the excavations of Natural Trap Cave as their arms would be much too small.

This ground breaking result is due to the pivotal observations of water by the Moon Mineralogy Mapper (M3), Visual and Infrared Mapping Spectrometer (VIMS), Deep Impact Extended Investigation (DIXI), and the Lunar Crater Observation and Sensing Satellite (LCROSS). Similarly, ground based radar observations and instruments onboard the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft have detected water ice in the permanently shadowed regions of Mercury. While these observations document the existence of water on these planetary surfaces, they do not completely explain the origin. Some proportion of this water maybe formed from a process known as recombinative desorption (RD) of solar wind implanted hydroxyls defects. This reaction is driven by thermal excursions from normal solar heating and impact events with meteoroids.

This April, the College of Sciences is hosting an inspiring look at the future of space exploration and life beyond Earth. Frontiers in Science: Advancing Space Exploration will convene leading scientists, engineers, policy experts, and thought leaders from across Georgia Tech and beyond to share research that’s guiding discovery and innovation.
Each year, Frontiers showcases how collaboration across disciplines — from science and engineering to public policy and international affairs — advances strategic research priorities. Recent programs have explored neuroscience and AI, climates in flux — and, this year, our solar system.
2026 Frontiers will convene more than 25 experts to discuss planetary science, satellites and orbital observation, robotic exploration, public astronomy, and bold visions for human spaceflight. The conference will also highlight the future of space policy, careers and commercialization, space as a laboratory, and will feature an “Astronaut’s Perspective” fireside chat with R. Shane Kimbrough (MS OR ’98) and Jud Ready, who serves as executive director of Georgia Tech’s new Space Research Institute (SRI) and GTRI principal research engineer.
Registration has closed as we are at capacity for full- and half-day passes.
Members of the community are welcome to drop by sessions of interest, lunchtime and evening telescope viewings, and our afternoon networking reception without RSVP. Come by and say hi!

You will be using clay pigments from exotic locations to paint with fellow Art-SpaceScience enthusiasts!
Dive into a hands-on workshop where scientific uncertainty becomes the starting point for creative exploration. Artist Eric Mack and scientist Jennifer Glass will introduce oxygen-free soil samples collected from locations around the world, originally prepared for long-running research experiments studying early Earth conditions and the possibility of life in extreme environments. Participants will begin by creating blind contour drawings of the field sites, embracing chance and limited control as part of the process, then use laboratory-inspired tools, minerals, and pigments to build layered paintings with the samples as they are exposed to the modern atmosphere for the first time.
Guided by both scientific observation and creative experimentation, you’ll explore how missteps, unknown outcomes, and changing conditions can lead to unexpected discoveries. No art experience required - just curiosity and a willingness to experiment with the beauty of failure.

While there are numerous extant strategies for achieving specificity, perhaps the most striking is the emergence of substrate tunnels: voids within the core of the protein that allow for specific molecules to traverse from site to site, without exposure to solvent. As these tunnels can extend up to tens of angstroms in length away from critical catalytic residues, there is often reduced conservation of tunnel-lining positions. This allows for enzyme-level adaptation to an organism’s environment through the evolution of a substrate tunnel’s composition.

While there are numerous extant strategies for achieving specificity, perhaps the most striking is the emergence of substrate tunnels: voids within the core of the protein that allow for specific molecules to traverse from site to site, without exposure to solvent. As these tunnels can extend up to tens of angstroms in length away from critical catalytic residues, there is often reduced conservation of tunnel-lining positions. This allows for enzyme-level adaptation to an organism’s environment through the evolution of a substrate tunnel’s composition.

These assume that shaking from CSZ earthquakes remobilizes seafloor sediment, but empirical observations of seismically-generated turbidity currents are lacking in the CSZ. Few quantitative estimates exist linking shaking intensity to turbidity current generation, challenging our ability to fully constrain past shaking and earthquake characteristics. The Ocean Networks Canada (ONC) cabled seafloor array in Barkley Canyon provides concurrent seismic, turbidity, and other oceanographic data in a seismically active portion of the margin. Multiple large regional (>M6) and moderate local (<M6) earthquakes occurred during the ONC operating period 2016-2023, allowing us to search for direct observations of shaking and concurrent canyon system processes.
Using the Barkley Canyon Axis (BACAX) oceanographic nearbed turbidity sensor data, we created a catalog of turbidity events at BACAX using a short-term average/long-term average (STA/LTA) algorithm to identify elevated signal levels with a subsequent exponential decay. To determine the likely cause, we examined associated oceanographic data (i.e., oxygen, temperature), and acoustic doppler current profiler (ADCP) velocities. We also computed shaking intensity from regional seismicity and theoretical strain measurements generated by large regional and teleseismic events. We evaluated correlations between the turbidity events and associated metadata. We found nearly all 50 events at BACAX are internal tide generated, and unrelated to shaking, except one down-canyon event that is not preceded by significant shaking or strain. We conclude that there were no statistically significant links between ground motions and turbidity events at this site. This method may be used at other canyon systems, where sediment transport processes may differ from the sediment-starved Barkley Canyon.

Marine sediment minerals, particularly highly reactive iron and manganese phases, help control organic carbon preservation and burial, the abundance and distribution of micronutrient trace metals, and play a pivotal role in the cycling of other elements—such as the rare earth elements—that are widely used to proxy Earth-system processes. Connecting these smallscale sedimentary reactions to large-scale Earth-system feedbacks provides critical constraints on, and levers within, the Earth system that can be used to explore planetary change over both geological and modern timescales. Here, we will see how marine sediment minerals control the preservation and burial of organic carbon through both sorptive protection and sorptive transformation, within a framework referred to as the Mineral Carbon Pump. Work indicates that interactions between organic carbon and iron and manganese minerals enhance carbon preservation efficiency, such that variations in iron and manganese fluxes to the ocean influence long-term carbon burial, climate, and oxygenation. We will also examine how marine sediment minerals regulate the concentrations and isotopic compositions of micronutrient trace metals and rare earth elements in sediments and seawater. Work shows that as manganese minerals age and transform during early diagenesis, they exert strong controls on metal retention and release, supporting a bottom-up perspective on ocean chemistry. Together, these studies exemplify the central role of sedimentary minerals in regulating elemental cycling and demonstrate the importance of experimentally constrained mineralogical processes for understanding the ancient and modern Earth system.

Central in this process are organic acids (e.g. acetate), small molecule intermediates generated as organic matter is broken down into greenhouse gases. Organic acids are rapidly turned over by microbial metabolisms and abiotic reactions alike. By combining method development, metabolic modeling and experimental geobiology, I harness organic acids as a window into the carbon cycle, informing both our understanding of anoxic microbial ecology and the potential for life elsewhere in the Solar System. In this seminar, I will present new Orbitrap mass spectrometry techniques that I have developed to measure precise isotope ratios of organic acids with unprecedented sensitivity.

A region of outstanding interest is Elysium Planitia on Mars. It is home to the youngest volcanic terrains, which are only a few million years old and the region may still be volcanically active. Elysium Planitia also exhibits the largest fluvial outflow channel carved in the late Amazonian epoch. By integrating geomorphological (CTX and HiRISE), geophysical (SHARAD and MOLA), and chronological constraints, we reconstructed the fluvial, volcanic, and magmatic evolution in Elysium Planitia.
While Mars’ surface is dominated by volcanic terrains, the surface and subsurface have experienced aqueous modification and are thus often shaped by an interplay between volcanic and aqueous activities. Many regions on Mars show signs of water–rock interaction, as indicated by the detection of hydrated silica by CRISM. Hydrated silica is significant for understanding past environmental conditions, such as the longevity and intensity of aqueous alteration. In addition to implications on aqueous conditions, siliceous materials—including opal—provide an excellent substrate to preserve biosignatures.
Further, analog sites here on Earth provide the means of testing our tools, approaches, and interpretations used in planetary sciences. The 2014–2015 Holuhraun lava flow-field in the Icelandic highlands provides a unique martian analog, allowing us to refine our understanding of eruption dynamics and lava morphology through a combination of remote sensing, unoccupied aircraft systems, and field observations. This seminar will demonstrate how these tools and techniques enhance our comprehension of effusive eruptions and the interactions between water and rock within volcanic terrains.

In this seminar, I will present an overview of my research that connects aerosol properties and processes to climate and health outcomes. First, I will discuss efforts to constrain historical fire emissions and aerosol radiative forcing using ice-core observations and inverse modeling. Second, I will highlight studies investigating climate-relevant aerosol properties and processes, including aerosol optical properties, mixing states, hygroscopicity, photolytic aging, and temperature sensitivity of particulate matter. Finally, I will describe emerging work linking aerosol composition and physicochemical properties to health outcomes, such as the neurodegenerative disease risks. Together, this work aims to advance a mechanistic understanding of aerosol impacts and bridge atmospheric chemistry, climate science, and environmental health.

Although there is robust consensus that rapid and steep cuts to anthropogenic greenhouse gas emissions must represent the core of climate mitigation, there is also increasingly broad consensus that significant residual greenhouse gas emissions will remain through the end of the century even under aggressive decarbonization scenarios. Limiting net climate warming in the coming decades will thus require both reducing emissions from hard-to-abate sectors and carbon dioxide removal (CDR) – directed intervention in Earth’s carbon cycle with the aim of transiently or permanently removing carbon dioxide from the atmosphere.
After providing a brief overview of our motivations and the range of systems we work on, this seminar will use agriculture as a concrete example of our approach toward understanding and deploying pathways that can reduce the net greenhouse gas emissions of key human systems. In the agricultural sphere this includes basic and applied research on the end-to-end impacts of soil acidity management in cropland systems and attendant carbon, nitrogen, and alkalinity flow, along with the development of open-source decision-support tools for land managers. In parallel, we pursue policy engagement across technical practitioners, jurisdictional agencies, and philanthropic non-profit groups with the aim of developing greenhouse gas management and carbon dioxide removal as public goods.

The largest transfers of volatiles and elements between Earth’s surface and deep interior occur at plate margins and above mantle plumes—regions that also host the planet’s most destructive earthquakes and volcanic eruptions. Because many of these systems lie beneath the ocean, direct observations are limited. Electromagnetic (EM) geophysical methods provide one of the few tools capable of imaging fluids and magmas at depth, and recent advances now enable offshore EM imaging at regional scales.
In this seminar, I present results from active seagoing projects led by the Electromagnetic Geophysics Laboratory (EGL) that image subseafloor fluids and magmas and their impacts on two processes: (1) subduction zone earthquakes and (2) plume-tectonic interactions. First, I show results from EGL imaging surveys at the New Zealand and Alaska–Aleutian subduction margins, which reveal the distribution of fluids along the plate interface and its implications for fault locking and earthquake hazards.
Next, we tour the eastern equatorial Pacific seafloor to explore the structure of the lithosphere and asthenosphere. By combining thermodynamically coupled Bayesian inversion of EM data with geophysical, geochemical, and drilling observations, I unravel the magmatic history of the Cocos plate over the past 20 million years. I end by highlighting a new marine survey that will image the mantle structure in the region.

Many of the greatest innovations in the history of life on Earth, however, are ‘evolutionary singularities’ – from the origin of life itself to eukaryogenesis to nitrogen fixation, they have appeared precisely once and gone on to change the world. Why are these innovations singular – are they very difficult to evolve with us only observing them due to anthropic selection effects, or do eco-evolutionary forces suppress the origin of newcomers in the face of incumbents? To approach this question, we study the evolution of phototrophy: the ability to use light for metabolic energy, one of the most significant metabolic innovations of all time. Unlike other singular innovations, this was invented exactly twice – chlorophototrophy and retinalophototrophy. This ‘dual singularity’ presents a unique opportunity to study the origins of evolutionary innovations: while apparently accessible enough to evolve twice, something has nonetheless limited its origins to only two. We find that these two forms cleanly ecologically partition phototrophic niche space, suggesting that each of them lays down an ‘evolutionary priority effect’ preventing the evolution of newcomers sufficiently similar to itself. This suggests that other singular innovations could be singular not due to difficulty of evolution, but due to eco-evolutionary feedbacks preventing the evolution of sufficiently similar forms. This further suggests that many major innovations taken to represent ‘hard steps’ in the evolution of a biosphere may instead be simpler to evolve than previously thought.

Michael Peterson Director, Severe Storms Research Center Georgia Tech Research Institute
Abstract: The modern interconnected world increasingly relies on technologies that are impacted by space weather. Common modes of radio communications are susceptible to disruption from all types of solar storms that perturb the ionospheric plasma. Disturbances impact signal propagation or create communications blackout conditions in critical high-latitude regions. Our ability to monitor these disturbances is limited to land via sensor density, to serendipitous orbital alignments, or to the source of the ionospheric disturbance – X-rays, energetic electrons, or energetic protons – in the case of operational modeling. Improvements to the spatial and temporal sampling of ionospheric disturbances regardless of radiation source is needed to provide improved situational awareness of disturbances, to quantify risk and impacts to advanced technologies, and to understand basic ionospheric physics questions. We are developing the FulminoSat constellation that will use distributed multi-modal space-based sensing of signals of opportunity (lightning) to complement current sensing systems to meet these needs.

On our planet, some of the most compelling natural laboratories for methane production and consumption occur in water–rock-hosted ecosystems formed during the geological process of serpentinization, where the resulting reduced, hyperalkaline fluids, low in dissolved inorganic carbon, and abundant hydrogen can mix with more oxidized fluids to create strong energetic disequilibria. These environments provide a window into how microbial life persists under extreme geochemistry that may resemble conditions on early Mars and within possible subsurface oceans of icy worlds such as Enceladus.
In this seminar, I synthesize insights from field and laboratory studies that integrate geochemical modeling, methane isotopic analysis, and microbial genomic studies of methane cycling in terrestrial serpentinizing systems of the Samail ophiolite in Oman to examine how microbial methanogenesis and methanotrophy operate at the extremes of carbon availability, pH, and energy supply. I focus on how microbial metabolisms respond to water–rock-reaction-driven chemistry, how methane isotopic signatures are generated and modified under these conditions, and what these patterns reveal about the coupling between geochemistry, physiology, and ecosystem function.
I then translate these Earth-based observations into an astrobiology framework, asking what methane can—and cannot—tell us about life in ocean-world environments. By integrating constraints on chemical energy, isotopic fractionation, and metabolic adaptation, this talk will highlight how studying methane cycling in water–rock-hosted ecosystems can refine life-detection strategies, inform interpretation of planetary methane measurements, and bridge fundamental astrobiology with broader questions about habitability across the solar system.

Accurately representing these phenomena remains a major challenge due to the strong coupling between turbulence, phase change, and multiscale interfacial dynamics. In this seminar, I will present recent advances in high-fidelity computational modeling of multiphase turbulent flows, with emphasis on applications relevant to atmospheric and environmental fluid dynamics. I will introduce a diffuse-interface (phase-field) framework designed to robustly capture interfacial dynamics in two-phase flows. The formulation is entropy-consistent and minimally dissipative, enabling accurate representation of droplets, bubbles, and phase boundaries embedded in turbulent environments. I will highlight simulations of droplet-laden and bubble-laden turbulence that serve as reduced-order analogs for cloud microphysics, aerosol–turbulence interactions, and air–water exchange processes. These examples provide insight into how multiphase structures modify turbulence statistics, mixing, and transport across scales.
In the final part of the talk, I will discuss extensions to coupled multiphysics problems involving surface interaction and phase change, including ice formation and heat transfer at solid–fluid interfaces. These processes share strong commonality with environmental freezing, icing, and cryospheric dynamics.

Become a fossil hunter and help discover how vertebrate communities have changed through time. Experience firsthand what it is like to be a paleontologist, finding and identifying new specimens!
You will be picking and sorting 3,000 to 30,000-year-old fossil specimens from rock matrix that has been brought back from Natural Trap Cave, WY. These specimens are part of many research projects examining how the community of species living around Natural Trap Cave has changed since the extinction of the cheetahs, lions, dire wolves, mammoths, camels, horses, and other megafauna that used to live in North America.
You are welcome to participate anytime that is convenient, with no commitment necessary. In fact, you can drop in or leave anytime within the two-hour timeframe. All are welcome, so bring your friends!
* No T. rex actually helped with the excavations of Natural Trap Cave as their arms would be much too small.

These specimens are part of many research projects examining how the community of species living around Natural Trap Cave has changed since the extinction of the cheetahs, lions, dire wolves, mammoths, camels, horses, and other megafauna that used to live in North America.
You are welcome to participate anytime that is convenient, with no commitment necessary. In fact, you can drop in or leave anytime within the two-hour timeframe. All are welcome, so bring your friends!
If you are accompanying a minor (under 18), please be sure that a guardian/chaperone is with them at all times and that there is no less than one adult for every two minors.
For more information join the mailing list and/or contact Katie Slenker (kslenker3@gatech.edu) or Jenny McGuire (jmcguire@gatech.edu).
* No T. rex actually helped with the excavations of Natural Trap Cave as their arms would be much too small.

Become a fossil hunter and help discover how vertebrate communities have changed through time. Experience firsthand what it is like to be a paleontologist, finding and identifying new specimens!
You will be picking and sorting 3,000 to 30,000-year-old fossil specimens from rock matrix that has been brought back from Natural Trap Cave, WY. These specimens are part of many research projects examining how the community of species living around Natural Trap Cave has changed since the extinction of the cheetahs, lions, dire wolves, mammoths, camels, horses, and other megafauna that used to live in North America.
You are welcome to participate anytime that is convenient, with no commitment necessary. In fact, you can drop in or leave anytime within the two-hour timeframe. All are welcome, so bring your friends!
If you are accompanying a minor (under 18), please be sure that a guardian/chaperone is with them at all times and that there is no less than one adult for every two minors.

]]><![CDATA[EAS Planetary & Astrobiology Seminar - Dr. Madison Turner]]>36678 Understanding the sedimentary rock record of Mars is an essential tool in understanding the planet’s evolving climate. Mars’ sedimentary record is broadly categorized into three units identified from orbit (the Clays, Laterally Continuous Sulfates, and Rhythmites) and hypothesized to span from warmer, wetter periods early in Mars’ history (Clays), to colder, dryer ones (Rhythmites). However, this model for Mars’ planetary evolution hosts many uncertainties around the post-3.5 Gyr portion of Mars’ history where water was scare, but sedimentary rock formation persisted. Thus far, we have been unable to resolve the spatial and temporal shifts recorded within and between Mars’ major geologic units. This limits our ability to distinguish between unidirectional and diachronous, localized transitions from warm and wet to cold and dry depositional environments. We address these unknowns by analyzing the post-3.5 Ga sedimentary record. We quantify Mars’ sedimentary rock production by measuring regional deposit volumes and ages. Additionally, we test against different global formation hypotheses (e.g. ash, dust) using layer thickness trends and locations of sedimentary depocenters. Lastly, we calculate the detailed aggradation rate of deposits to better understand when Mars was actively producing sedimentary rocks, how that evolved over time, and how it relates back to Mars’ climate and stratigraphic evolution. We found that Mars’ global sedimentary record shows intra-regional, rather than global, trends in layer thickness, disfavoring global formation mechanisms despite globally consistent stratigraphy. Furthermore, we show that Mars’ global stratigraphic transitions are diachronous. We also find evidence that aggradation during different time periods was relatively constant. Together, these data provide a time integrated view of the macrostratigraphy of Mars’ young (post 3.5 Ga) sedimentary rocks.]]> tbuchanan9117685733772026-01-16 14:22:5717685771042026-01-16 15:25:0400eventUnderstanding the sedimentary rock record of Mars is an essential tool in understanding the planet’s evolving climate.

There is evidence to suggest that Mars hosted hypersaline systems with a variety of chemistries prior to the loss of its atmosphere. Although the modern surface of Mars no longer hosts liquid water, Mars is a prime astrobiological target since it lost its atmosphere around the onset of life on Earth. This begs the question: can life have arisen on Mars at the same time? To probe these questions, environments that are similar (analogs) to ancient Martian brines (or other planetary bodies) are required to understand fundamentals such as which chemistries are more conducive to the production and/or preservation of life signatures. Terrestrial hypersaline environments are promising locations to probe for the potential for life beyond Earth due to many of their chemistries resembling ancient Martian brines and icy moons. My primary work seeks to better understand these environments and their potential biosignatures including lipid biomarkers, organic carbon, and stable isotopes. Additionally, I aim to improve life detection efforts by bridging the gap between organic geochemistry, astrobiology, and data science to unravel hidden patterns and features in complex environmental datasets.

Become a fossil hunter and help discover how vertebrate communities have changed through time. Experience firsthand what it is like to be a paleontologist, finding and identifying new specimens!
You will be picking and sorting 3,000 to 30,000-year-old fossil specimens from rock matrix that has been brought back from Natural Trap Cave, WY. These specimens are part of many research projects examining how the community of species living around Natural Trap Cave has changed since the extinction of the cheetahs, lions, dire wolves, mammoths, camels, horses, and other megafauna that used to live in North America.
You are welcome to participate anytime that is convenient, with no commitment necessary. In fact, you can drop in or leave anytime within the two-hour timeframe. All are welcome, so bring your friends!
If you are accompanying a minor (under 18), please be sure that a guardian/chaperone is with them at all times and that there is no less than one adult for every two minors.
For more information join the mailing list and/or contact Katie Slenker (kslenker3@gatech.edu) or Jenny McGuire (jmcguire@gatech.edu).
* No T. rex actually helped with the excavations of Natural Trap Cave as their arms would be much too small.

Yet nearly 45% of these ecosystems have been degraded or burned due to land use conversion mostly for oil and forest plantations, making peatlands both a major emissions source and Indonesia’s greatest climate mitigation opportunity.

Our recent research demonstrates that rewetting oil palm plantations reduces peat decomposition by 34%, delivering immediate emissions benefits. On the ground, we translate science into impact by installing canal blocking systems with real-time groundwater and GHG monitoring, restoring vegetation through revegetation and agroforestry, and supporting community livelihoods through sustainable peat-friendly commodities. At the national level, we support the Ministry of Environment to improve methodologies and strengthen carbon projects from peatland ecosystem.

While surface processes are increasingly well-observed, the "hidden half" of these systems (e.g., the subglacial water networks and basal thermal states that lubricate ice flow) remains critically under-constrained. In this talk, I will demonstrate how my research group, the Polar Geophysics Simulation Lab (PGSL), is closing this gap by bridging the historical divide between observational geophysics and numerical modeling.
I will first present results from our "Frozen Legacies" program, where we have utilized historical and modern radar sounding data to map basal freeze-on and ice shelf basal channels across Antarctica. I will highlight recent findings from the Amundsen Sea Embayment, where our integration of radar attenuation with ice-flow models has revealed that frozen beds upstream of Thwaites Glacier are poised to thaw under moderate acceleration, producing a feedback mechanism with urgent implications for ice sheet stability.
Moving beyond observation, I will outline the future trajectory of my program, enabled by recent NSF CAREER and Heising-Simons Foundation awards. I will discuss our development of physics-informed AI frameworks that assimilate multi-scale radar observations into hydrologic models, allowing us to infer basal conditions at resolutions previously impossible. By moving from static mapping to dynamic, AI-enabled forecasting, we aim to bridge the gap between observation and prediction, providing the constraints needed to reduce uncertainty in the next generation of ice sheet models.

While often visualized as a vacuum separated from Earth by the Karman line, the near-Earth environment is actually a dynamic reservoir of relativistic particles that actively interact with the planet below. In this seminar, I will discuss how the Van Allen radiation belts act not just as a hazard for satellites and astronaut exploration, but as a source of "top-down" forcing that leeches energy deep into the upper and middle atmosphere. During magnetic storms, these highly relativistic space radiation precipitate well below the edge of space, driving ionization as well as producing NOx/HOx species and catalyzing ozone destruction, thus, potentially altering regional weather or climate dynamics.
I will explore the physics governing this coupling, focusing on self-limiting mechanisms in which energetic electrons drive plasma whistler waves that subsequently scatter and constrain the particle population. I will present recent evidence showing how this fundamental plasma process acts as a natural "safety valve," capping natural and artificially created radiation intensity by scattering particles into the atmosphere, thus effectively trading satellite safety for atmospheric energy input.
To fully resolve these dynamics, we must move beyond the era of single-point satellite measurements. I will discuss my work developing next-generation miniaturized particle detectors, which allow for the "pixelation" of geospace via distributed satellite networks. I will conclude by presenting results from a student-led balloon mission launched during the historic May 2024 superstorm, carrying a prototype of this detector and demonstrating how hands-on hardware development can simultaneously advance fundamental physics, train the future space workforce, and close the observational gap in our understanding of the Earth system.

This combined study integrates high-resolution topographic analysis, multispectral satellite observations, and geodetic measurements to examine how thermal, hydrologic, and anthropogenic drivers reshape terrain in two of the most sensitive Earth environments: the permafrost-dominated Arctic coastal zone of Utqiaġvik, Alaska, and coastal landscapes of the southeastern United States and the Souss Massa Basin of Morocco.
In Arctic permafrost terrain, a 0.5 m LiDAR-derived DEM was used to delineate ice-wedge polygon morphology and evaluate structural variability through comparisons with Thiessen polygon networks. Hydrologic modeling—including compound terrain analysis, drainage extraction, and surface flow simulation—revealed strong spatial correspondence between modeled flow paths and trough networks. High TWI (>12) and SPI (>60) values highlight zones of surface saturation and flow concentration that promote ice-wedge thaw, slow overland flow, and persistent ponding, contributing to wetland formation. These results demonstrate the critical role of surface hydrology in driving ice-wedge degradation and permafrost landscape evolution.
Complementary coastal studies illustrate parallel vulnerabilities in non-permafrost environments. Airborne LiDAR from NOAA (2006–2018) was used to quantify elevation and sediment volume changes along the southeastern U.S. coast, revealing quasi-cyclic patterns in unconsolidated sediment distribution linked to sea-level fluctuations and storm-driven coastal erosion. Sentinel-2 imagery (2016–2020), processed with supervised and unsupervised ENVI classification, identified spatial and temporal changes in salt-marsh extent, with maximum likelihood classification yielding >90% accuracy in distinguishing marsh and open-water environments. In the Souss Massa Basin of Morocco, InSAR and GRACE analyses captured the coupling between groundwater depletion and land deformation: groundwater storage losses of ~10 cm (2016–2021) coincided with subsidence of ~2 cm, demonstrating how anthropogenic extraction accelerates geomorphic instability.
Together, these integrated investigations highlight the power of multi-sensor remote sensing—LiDAR, multispectral imagery, InSAR, and hydrologic modeling—for detecting terrain change, interpreting hydrologic connectivity, and assessing environmental vulnerability across diverse yet increasingly threatened landscapes. The combined framework provides a scalable methodological foundation for long-term monitoring of Arctic and coastal systems and for anticipating future impacts of climate change, sea-level rise, and groundwater exploitation on surface processes and ecosystem resilience.

This talk explores the earth’s surface responses to this deep-seated tectonic process across several modern zones in South America. In Peru, we present compiled geochronologic, geomorphic, and thermochronologic datasets which document arc shutoff, rock uplift, and shifts in drainage morphology during subduction of thick oceanic crust. In Colombia, we present geologic field datasets and landscape analysis that support connections between the formation of large river systems and changes in slab dynamics. Overall, we show that the subduction of thick oceanic crust promotes erosion, rock uplift, and drainage reorganization in the overriding continental crust.

Ocean warming has been implicated as a driver of glacier retreat, with submarine melting as the presumed link. However, at the termini of tidewater glaciers – where glaciers meet the ocean with a near-vertical ice cliff – we lack observations of submarine melting or the oceanic processes that control melt. Instead, many studies rely on untested theory and parameterizations to estimate submarine melt rates. These frameworks often hinge on buoyant plumes, whose small-scale dynamics can modulate both the ocean’s impact on the glacier through melting and the glacier’s impact on the ocean through freshwater input. In this talk, I will present ocean surveys from two complementary field campaigns at Kangerlussuup Sermia, Greenland, and LeConte Glacier, Alaska. At both sites, autonomous vessels surveyed near the glacier, in a region that is otherwise inaccessible due to iceberg hazards, while simultaneous measurements were collected downstream from a ship and upstream on the glacier. We assess the structure and dynamics of upwelling plumes, both the energetic primary plumes and weaker secondary plumes, and the links between plumes, submarine melting, and glacier dynamics. We propose modifications to the standard approach for parameterizing melt, aiming to improve models of ocean-glacier interactions and work towards more accurate projections of sea level rise.

While most megaflood research focuses on low-relief systems, their behavior in mountainous terrain remains poorly understood. The Yarlung-Siang River in the eastern Himalaya offers an ideal case study, with evidence of repeated Quaternary megafloods sourced from glacially-dammed lakes on the Tibetan Plateau. Using 2D hydraulic simulations of an 81 km3 paleolake outburst, this work demonstrates that valley morphology fundamentally controls megaflood hydraulics, creating erosional patterns that differ dramatically from modern stream power distributions. These simulations reveal megafloods can deposit boulders >4 meters in diameter throughout the flood pathway—far larger than the modern river can transport. Field observations confirm 106 boulder bars containing boulders >4 m in diameter. To understanding the long-term landscape impacts of these massive, immobile boulders, we can use a 1D landscape evolution model to incorporate boulder effects on channel erosion. Results show megaflood boulder bars generate meter-scale knickpoints persisting >20 kyr, fundamentally altering local channel steepness. With repeated megaflood during glacial periods, these effects compound, creating stepped longitudinal profiles. This work demonstrates that megaflood legacies extend beyond erosion to include persistent depositional effects influencing landscape evolution for millennia.

At Costa Rica’s IrazÅLu volcano, we document days-to-weeks of evolving precursory signals preceding the December 2014 and August 2020 flank collapses, including a progressive increase in repeating low-frequency events (LFEs) and lowperiod tremor that intensifies as failure approaches. These observations, synthesized from dense local networks and retrospective analyses, indicate a transition from quasi-stable to unstable sliding within a deforming, fluid-affected hillslope—analogous to fault weakening prior to earthquake nucleation. The repeating character and spectral content of the LFEs suggest episodic aseismic slip and/or fluid pressurization in damage zones acting as “stick-slip” asperities that load the slope to failure, offering a quantitative basis for near-real-time anticipation. Building on these results, we report ongoing near-field monitoring of the Aguas Zarcas rockslide complex in north-central Costa Rica with a compact array of nodal seismometers. Continuous recordings there capture families of LFEs and emergent tremor during rainfall and pore-pressure transients, supporting a unified framework in which landslide precursors map the evolution of effective stress toward runaway acceleration. Together, the IrazÅLu and Aguas Zarcas case studies demonstrate that (i) LFE rate changes and repeating-event statistics are actionable indicators for shortterm landslide forecasting, and (ii) landslides provide accessible natural laboratories for probing earthquake nucleation physics—linking frictional weakening, fluid coupling, and rupture initiation across scales. Our findings motivate operational landslide early-warning strategies that fuse LFE detection, template matching, and trend analysis with hydrometeorological inputs, while also informing constitutive models of fault and slope failure that explicitly incorporate damage and fluids.

This additional warming is caused by the urban heat island effect, in which the built environment traps heat during the day, and retains that heat through the night. Despite this risk, we lack reliable, high-resolution observational data to adequately characterize the urban heat island effect and its impact on health and energy systems. When these data do exist, they are often noisy, biased, and unevenly distributed. In this talk, I will present statistical and machine learning approaches that transform these fragmented data into reliable, high-resolution maps of neighborhood-level heat exposure. Using techniques from causal inference, this work provides actionable insights for climate adaptation, so we can better evaluate cooling strategies such as reflective surfaces and urban greenery. I will conclude by outlining future research directions.

In this seminar, I will discuss remote sensing techniques to study sea ice processes across both hemispheres. Using a multi-sensor approach that integrates altimetry (ICESat-2 and airborne lidar), and optical, multispectral and hyperspectral imagery (e.g., MODIS, Sentinel-2, WorldView, Planet), we explore key properties such as surface type, melt pond evolution, floe size distribution, and marginal ice zone characteristics. New high-resolution sensors and data fusion techniques are enabling improved surface classification and freeboard estimation, particularly during the summer melt season when traditional algorithms struggle. These methods are especially valuable in regions where field measurements are sparse or unsafe due to dynamic or degraded ice conditions. As the physical structure and spatial extent of sea ice continue to degrade, remote sensing provides insight into its basin-wide evolution and supports the development of new model parameterizations for forecasting polar change.

However, most olivine deformation studies available, focused on “steady state” creep, and studies on transient creep are limited. Transient and “steady-state” creep involve different microscopic mechanisms particularly for dislocation creep (different slip systems) [3, 4].
Here I will be presenting results on transient creep obtained during in-situ high pressure deformation of olivine aggregate deformed in D-DIA for pressure between 3-7GPa and temperature ~ 1200C. strain was estimated from X-ray radiography of the samples during deformation. In all experiments, stress was estimated from X-ray diffraction of an isotropic stress sensor, Pyrope. The pyrope stress was compared with the estimated stress from the olivine aggregate deforming in dislocation creep regime.
Results show that, during deformation, olivine aggregate present a large (hkl) stress dependence due to large plastic anisotropy throughout the deformation, while pyrope shows much smaller (hkl) stress dependance (≤ 10%). Therefore, pyrope stresses represents the average stress of the olivine aggregate [5]. The comparison between the stress estimated from pyrope and the olivine aggregate seems to indicate a change in deformation mechanisms between transient creep and steady state creep. At low strain, pyrope stresses match the stresses in Olivine soft (hkl) (soft slip system). However, at large strain (steady state) stresses estimated from pyrope match the stresses in Olivine hard (hkl) (hard slip system).
These results have significant implications for small-strain geophysical processes, such as glacio-isostatic adjustment (GIA) and post-seismic creep. The depth and regional variations in rheological properties derived from GIA and post-seismic creep reflect largely the properties of the soft slip system(s) and are likely distinct from those relevant to mantle convection which is controlled largely by the hard slip system(s).

During the last decade, its atmospheric levels have risen faster than previously estimated, highlighting the need to better understand its sources. While microbial processes like ammonia oxidation and denitrification are known contributors, our recent research has uncovered a novel abiotic pathway—photochemodenitrification—where sunlight drives N2O production from nitrite in oxygen-rich surface fresh and marine waters. In addition, photochemodenitrification exceeded biological N₂O production in surface waters. Our latest findings reveal that this photochemical process also occurs in polar regions and the tropical open ocean, emphasizing its global distribution. Because it occurs in surface waters in direct contact with the atmosphere, photochemodenitrification holds the potential to contribute significantly to N2O emissions.

These parallels make Venus a cosmic gift for understanding planetary evolution. Yet this planetary ‘control case’ constantly highlights fundamental gaps in our comprehension of forces that shape interior convection, surface geology, and ultimately habitability. Today, Venus is dramatically uninhabitable, with a surface temperature of 460°C and a pressure of 90 bars. Although once predicted to have plate tectonics, Venus displays no such interconnected network of plate boundaries. Instead, Venus appears more like early Earth, prior to full scale plate tectonics - but without interference from erosion or sedimentation. The intense greenhouse keeps the lithosphere hot. Large plateaus may be analogs of proto continents. There are numerous examples of possible subduction, interpreted as sinking slabs absent horizontal plate motion. Our challenges of applying Earth-centric ideas of how planets operate to our twin, along with the limited data availability, have made Venus prone to controversy. Does the deep interior retain more water than Earth or is it dry? Is the lithosphere strong or weak? Or, is temperature or water more important? Is Venus geologically active on a regional scale, or did it experience a massive geologic event that removed craters and killed most subsequent activity? What allows for a huge range of mantle plumes sizes? This talk gives a view of Venus, mostly through the lens of ‘coronae.’ These enigmatic volcano-tectonic features are (arguably!) unique to Venus, and thus may shine light on what makes the twin planets evolutionary paths distinct.

Their interactions with large-scale solar wind structures can significantly alter their properties during propagation, increasing their complexity and making space weather forecasting more challenging. To improve predictions at Earth, it is crucial to study CMEs near the Sun, in their early evolutionary phases, and track their progression through the heliosphere. So, what does this have in common with space weather at Mercury? The answer lies in a unique dataset from the MESSENGER mission. I will discuss how we have used MESSENGER data, along with observations from other spacecraft, to investigate both CME evolution and Mercury’s magnetosphere. In extreme cases, CMEs observed by MESSENGER have compressed Mercury’s dayside magnetosphere to the planet’s surface, which is an event that, to date, has not been observed in situ at any other planet. This finding also has implications for close-in exoplanetary systems.

Their interactions with large-scale solar wind structures can significantly alter their properties during propagation, increasing their complexity and making space weather forecasting more challenging. To improve predictions at Earth, it is crucial to study CMEs near the Sun, in their early evolutionary phases, and track their progression through the heliosphere. So, what does this have in common with space weather at Mercury? The answer lies in a unique dataset from the MESSENGER mission. I will discuss how we have used MESSENGER data, along with observations from other spacecraft, to investigate both CME evolution and Mercury’s magnetosphere. In extreme cases, CMEs observed by MESSENGER have compressed Mercury’s dayside magnetosphere to the planet’s surface, which is an event that, to date, has not been observed in situ at any other planet. This finding also has implications for close-in exoplanetary systems.

However, an underlying assumption that δ34Spyr variation is related to global S-cycle drivers is refuted by a growing number of observations. To elucidate the controls on δ56Fepyr and δ34Spyr values, we combine (i) bulk and microscale multi-isotope (Fe and multi-S) analyses of well-understood Pleistocene marine sediments, and (ii) a coupled microbial-diagenetic model, which accounts for the transport and (bio)reaction of C, S and Fe species.
Rather than global Fe-cycle and S-cycle drivers of isotopic variation, the studied sediment cores demonstrate clear controls by local variations in depositional parameters like the sedimentation rate, organic matter and reactive Fe content, and reworking by currents. Incorporating these insights into a microbial-diagenetic model, and using gridded datasets of the relevant depositional factors, we reproduce modern δ34Spyr spatial patterns and distributions compiled from the sedimentary rock record. In agreement with the bulk and microscale observations, the model microbial S isotope fractionation remains uniformly large under modern marine conditions, and the main determinants of isotopic variations in pyrite are the depositional parameters. These factors govern the degree of sulfate drawdown and isotopic distillation, and the degree of porewater sulfide accumulation, and through these, the distribution of δ34Spyr.
With the understanding that mostly local depositional parameters control the isotopic composition of pyrite, coupled δ56Fepyr, δ34Spyr and Δ33Spyr measurements by secondary-ion mass spectrometry (SIMS) offer a way forward. Such measurements provide a wealth of information about microbial activity, pyritization pathways, burial diagenesis and the dynamics of the depositional system.

Construction of this high-elevation domain has been variably attributed to isostatic uplift during crustal thickening induced by internal shortening, underthrusting during growth of the external thrust belt, or lower crustal flow. Alternatively, uplift may be related to dynamic processes associated with lithospheric foundering or flat-slab subduction. Each of these processes operates over predictable spatiotemporal scales and has been attributed to discernable structural, stratigraphic, topographic, magmatic, and/or thermal records in the overriding South American plate.
This study integrates new and published geo/thermochronological, structural, magmatic, and sedimentological datasets to reconstruct Andean evolution and evaluate the potential drivers of uplift and exhumation. We additionally showcase new kinematic and thermal history modeling techniques that quantitatively integrate the spatial relationships among geo- and thermochronology samples to inform thermotectonic interpretations. Results highlight the importance of internal shortening, as well as underthrusting linked to shortening in the external, retroarc thrust belt, in controlling uplift and exhumation of key segments of the thick, elevated hinterland domain. Findings further underscore the utility of our modeling approach in testing spatial, topographic, and structural hypotheses and deciphering the timing, magnitude, and mechanisms of exhumational cooling under varied geodynamic conditions.

This vertical movement of water transports biogeochemical and physical properties, impacting biological productivity, air-sea gas fluxes, as well as heat and freshwater budgets. Coincident and co-located observations of physical and biogeochemical properties remain rare and processes at the oceanic mesoscale and submesoscale (1-100 km) are not explicitly resolved in global climate models, highlighting the necessity to investigate these complex interactions. Here, I use data collected by autonomous underwater vehicles and satellites to observe ventilation via mesoscale and submesoscale motions. Subsurface distributions of biological tracers like oxygen demonstrate that rapid exchange of surface and interior water preferentially occurs at the edges of mesoscale eddies. To quantify the impact of these small-scale vertical motions on ocean ventilation, particularly in a warming ocean, we employ idealized numerical models. We find that motions at the submesoscale play a leading order role in oceanic ventilation and that ventilation’s response to warming is non-linear. Despite an a priori expectation that surface warming may reduce ventilation, we find that uptake via submesoscale processes may saturate and there may not necessarily be a reduction in ventilation via small-scale motions. Diagnosing and quantifying ventilation patterns and pathways is necessary to predict long-term trends in carbon and heat uptake, particularly at polar latitudes.

Among the key climate change forcings, greenhouse gases (GHGs) and aerosols play dominant yet contrasting roles, with aerosols partly offsetting some of the warming induced by GHGs. However, how these competing influences shape TC frequency remains poorly constrained. While TC intensity is expected to increase with GHG-induced warming, the response of TC frequency remains highly uncertain, with some models projecting an increase and others a decrease. Aerosols, meanwhile, can dampen some of the warming effects of GHGs but remain one of the least understood components of the climate system, largely due to their complex interactions and regionally heterogeneous effects. In this talk, I will present a physically constrained framework that integrates single-forcing climate model experiments with empirically derived TC genesis indices to disentangle the relative impacts of GHGs and aerosols on TC frequency. I will also examine the large-scale climate dynamics underlying these responses, an often overlooked but essential component of the problem. This approach provides an internally consistent methodology for assessing how key climate forcings influence TC frequency, notwithstanding the direction of the projected change, and will highlight the unintended climate consequences of air quality improvements—a tricky trade-off with significant policy implications.

This stage of rapid ice loss likely began in the mid-20th century, but due to limited instrumental data, the climatic drivers that initiated ice loss remain poorly understood. In West Antarctica — the most rapidly melting region of Antarctica -- the ice sheet melts via wind-driven exposure to warm ocean water. While widely used historical climate simulations suggest that strengthening local westerly winds are responsible for initiating ice loss, I will show in this talk that proxy records (i.e., ice-core and coral records) provide no evidence that local westerly winds strengthened; they instead show that northerly winds strengthened. I will also present results from a new ensemble of high-resolution ocean simulations, which provide evidence that local northerly winds, interacting with coastal polynyas, are the dominant driver of warm water transport toward the ice sheet. Together, the proxy data and ocean simulations point to a new explanation for historical ice loss, triggered by northerly winds. This transformation in our understanding of the drivers of Antarctic ice loss invites many new questions to guide future research, including potential connections to anthropogenic forcing.

First, we introduce probabilistic TC models that can be used to generate large numbers of synthetic storms with physically correlated characteristics under projected climate conditions. Second, we discuss about TC wind, rainfall, and surge hazard modeling, and the coupling with the TC models to estimate individual and compound hazard probabilities. Then, we discuss about infrastructure vulnerability modeling, and the coupling with the TC hazard projection to estimate future TC risk and develop risk management strategies.

These precipitation, driven by various mechanisms across multiple timescales and energy ranges, can penetrate different layers of the ionosphere, reaching as deep as the upper atmosphere, where they alter its chemical composition and produce significant radiation effects.

These precipitation, driven by various mechanisms across multiple timescales and energy ranges, can penetrate different layers of the ionosphere, reaching as deep as the upper atmosphere, where they alter its chemical composition and produce significant radiation effects.

Thus, planetary habitability is not constant. Instead, it varies temporally on a 10,000-year to million-year scale due to internal (e.g., volcanism, plate tectonics) and external (e.g., Milankovitch cycles, asteroid/cometary impacts) perturbations. Typically, studies have focused on analyzing long-term planetary habitability for Earth & other planetary bodies considering long-term changes (10s of millions to billions of years) in stellar insolation, volcanism, and weathering, using coupled planetary surface-interior evolution models. However, there is limited work on how shorter-term solid Earth perturbations affect the carbon cycle and planetary habitability - something we know is important from paleoclimate records over the past few 100 million years. In this talk, I will discuss my group's ongoing work to address this gap by analyzing the dynamics of the ocean carbon cycle, since it controls the rate of ecosystem recovery, by focusing on two primary features: (a) the role of solid Earth boundary conditions, especially global ocean bathymetry, on climate dynamics and ocean chemistry and (b) the effect of large-scale volcanism on surface climate and habitability. Using a combination of carbon cycle models and geophysical data analysis, I will describe how these perturbations affect planetary habitability on a mechanistic scale and how these results can be used to understand evolving climate on a variety of timescales.

Despite recent progress in modeling hurricanes, the turbulence dynamics of hurricanes is not well understood due to the lack of sufficient measurements and high-resolution simulations. In this talk, we aim to bridge this knowledge gap by using high-resolution turbulence-resolving large-eddy simulations (LESs). To this end, a novel high-fidelity LES solver will be used to reveal distinctive turbulence dynamics of hurricane boundary layers (HBLs) compared to regular atmospheric flows. Despite the unique features of HBLs, the current turbulence schemes in numerical weather prediction (NWP) models are neither specifically designed nor comprehensively tested for hurricane flows. We will present the implications of these new insights into the turbulence parameterization of NWPs by conducting real hurricane simulations in the Weather and Research Forecasting (WRF) model. Our results indicate that the current turbulence schemes in WRF are overly diffusive for simulating major hurricanes mainly since they do not account for turbulence suppression effects due to rotation in hurricanes. Reducing the vertical diffusion in the default planetary boundary layer (PBL) schemes led to ~30-40% improvements on average in hurricane intensity forecasts compared to the default models in the five considered cases. Finally, the implications of these diffusion changes on hurricane precipitation and flood forecasts will be shown by coupling the WRF atmospheric model with the WRF hydrological model. Modifying the diffusion not only impacts hurricane intensity but also modulates precipitation patterns and streamflow forecasts. Intensified hurricanes were shown to generate more intense and localized precipitation. This improved representation of hurricane dynamics led to enhanced flood forecasts in the considered cases. In total, we found that reducing the vertical diffusion led to ~16% and 34% average improvements in streamflow bias and correlation forecasts, respectively, in four landfalling hurricanes. This research provides new insights into the turbulence dynamics of hurricanes and can guide the development of more accurate models for forecasting hurricane winds and floods.

In southwestern Canada, these observations indicate that the Cordillera mountain belt is characterized by a hot, thin lithosphere (60-70 km thick), whereas the Laurentian Craton to the east is much cooler and thicker (200-300 km). The transition in lithosphere thickness occurs approximately below the Rocky Mountain Trench, resulting in a >100 km subvertical lithosphere step. The origin of the thin Cordillera lithosphere and the lithosphere step is unclear. One hypothesis is that this structure is inherited from Cordillera accretion at >100 Ma. Alternately, it may have formed through more recent gravitational thinning of the Cordillera, possibly during a large-scale delamination event in the Eocene. Using geodynamic numerical models, we explore these competing ideas and demonstrate how they may be discriminated using surface observations. The models also show that regardless of how the step formed, the present-day thin lithosphere requires that the Cordillera mantle must be undergoing rapid small-scale convection, possibly associated with the adjacent Cascadia subduction zone. The mantle flow patterns may be influenced by the presence of the lithosphere step, which enhances the Cordillera-Craton thermal contrast; the Craton edge may also be undergoing deformation. The models highlight the range of mantle dynamics that can shape the continental lithosphere and create temporal variations in surface topography and magmatism.

Whistler waves, in particular, play a dual role by both accelerating electrons to “killer” energies within the radiation belts and driving their precipitation from the magnetosphere into the upper atmosphere. At Earth, whistler-mode chorus waves are typically found outside the plasmasphere, while hiss waves are predominantly within it. In contrast, the Jovian magnetosphere frequently shows both chorus and hiss waves occurring simultaneously. Recent missions, such as Van Allen Probes and THEMIS, have provided invaluable insights into radiation belt electrons, whistler waves, and their wave-particle interactions at Earth. Meanwhile, the Juno mission provides a unique opportunity to reveal the typical characteristics of whistler waves and explore how whistler waves interact with energetic electrons in Jupiter's magnetosphere. In this seminar, I will discuss recent advances in understanding the global properties of whistler waves and their impact on energetic electrons at both Earth and Jupiter, using a multidisciplinary approach that combines satellite observations, physics-based simulations, and machine learning models. This comparative analysis will highlight similarities and differences in wave-particle interactions at Earth and Jupiter, providing insights into how whistler waves contribute to electron acceleration and precipitation, with implications extending beyond Earth and Jupiter to other magnetized celestial bodies.

The dynamics of fluid flow in ductile rocks is fundamentally different from standard porous flow in rigid or elastic rocks. Initially will focus on the pore-scale distribution of fluids in ductile rocks. The percolation of fluids in ductile rocks is thought to be governed by textural equilibrium. In the first part of this talk we test this hypothesis with laboratory experiments on rock salt and show that it can explain fluid distributions in salt from exploration wells in the Gulf of Mexico. Our results suggests that salt domes may be conduits for fluid flow at depth. In the second part, we explore hysteresis in texturally equilibrated pore networks. This work is motivated by the long-standing problem of core formation in primordial planetesimals, where segregation of metalsulfide melt is thought to be prevented by a percolation threshold. We compute the texturally equilibrated melt networks in realistic polycrystalline rocks and demonstrate that despite the percolation threshold the metal-sulfide melts can be drained due to hysteresis in melt network connectivity. This suggests that core formation by melt percolation is possible in primordial planetesimals, which may explain early core formation in these bodies. The third part of this talk will focus on melt transport at larger scales. At the Darcy-scale fluid low in ductile rocks inevitably leads to the formation of porosity waves. This work is motivated by oxidant transport through Europa’s ice shell. Using a Lagrangian analysis of melt transport we demonstrate that porosity wave can transport geochemical signatures over long distances. Preliminary results on kinematics of melt transport show that melt transport in porosity waves is robust in the presence of perturbations. This suggests that porosity waves provide a potential mechanism for oxidant transport from the surface to the internal ocean.

In physics, math, and engineering, women should not expect to reach parity for more than a century. The gender gap in science and technology is narrowing, but at a decidedly unimpressive pace. And even if parity is achievable, what about equity? This talk will present a large-scale empirical analysis of the global gender gap in science, providing strong evidence that the structures of scientific production and reward impede women’s career advancement. The evidence is drawn from publication and survey data and shows that women are systematically denied the chief currencies of scientific credit: publications and citations. The rising tide of collaboration only exacerbates disparities, with women unlikely to land coveted leadership positions or gain access to global networks. The findings are unequivocal: when published, men are positioned as key contributors and women are relegated to low-visibility technical roles. The talk concludes with a discussion of how intersecting disparities in labor, reward, and resources contribute to cumulative disadvantages for the advancement of women in science and what might be done to mitigate this.

Seismicity and deformation provide constraints on Kīlauea’s shallow magmatic system, but geophysical imaging remains sparse outside the summit area. I will present geophysical model results from magnetotelluric data that cover the entire subaerial volcanic system. 3D resistivity models image a stacked magmatic system, with shallow and deep reservoirs connected by seismicity. The shallow system connects the summit to Pu`u O`o cone, the source of near continuous eruption from 1983-2018. A deeper magmatic system containing 3-4 km3 of melt is thought to have fed the 2018 eruption along the lower ERZ. No electrically conductive connection exists between the summit and the 2018 eruption vents, implying that the dikes feeding the eruption solidified on a time scale of month to years. Different transport pathways through Kīlauea’s complex magmatic system can explain the varied observations (seismicity, geobarometry, petrology, deformation) and styles of eruption (summit, fissure, and extra-caldera vent eruptions as well as rift-zone intrusions). The F-shaped magmatic system further explains aspects of the 2018 eruption chronology and places melt inclusion data from this and prior eruptions into context. Finally, the geophysical model sheds light on tectonic/ magmatic interactions, such as the escape of Kīlauea’s mobile south flank, and the evolution of the volcano, including formation of its cumulate core and migration of its rift zones through time.

In contrast to areas dominated by land-terminating or smaller marine-terminating glaciers, the main inputs of glacial sediment and meltwater to the Amundsen Sea are focused along the grounding line within the ice shelf cavity, many kilometers from the open ocean. Additionally, the open polynyas along the coast host the most productive phytoplankton blooms in the coastal Antarctic, with maximum production limited by the availability of nutrient iron (Fe). The Amundsen Sea sediments and benthic ecosystem are likely important for supplying Fe to the overlying water, and may be influenced by grounding line retreat and ongoing melt rate increases. However, the biogeochemistry of the sediments in this setting is not currently well understood due to limited sampling. In order to characterize the benthic biogeochemical conditions and trace metal cycling, we collected 19 cores from the Amundsen Sea and analyzed the sediments for pore water trace metal concentration, solid reactive Fe contents, and total organic carbon along with other geochemical and physical parameters. We calculated diffusive benthic Fe fluxes and explored the importance of this source using a 3D circulation model of the embayment, comparing the results to observed water column Fe concentrations. Using this extensive dataset, we identify the biogeochemical and physical controls on benthic trace metal cycling and fluxes in the unique Amundsen Sea system, comparing to other well-studied high latitude systems. Overall, this research aims to establish a baseline of sediment biogeochemistry in the Amundsen Sea against which to monitor disturbances caused by climate change, and to predict downstream effects on the local ecosystem and carbon cycle.

The stratigraphic location of a megathrust fault impacts the local frictional properties of the fault, directly influencing the magnitude of an event. The CSZ has previously shown near-trench variability in the stratigraphic level of the megathrust, but few constraints exist at greater depth or throughout the margin. In this talk, I will present results from the CAscadia Seismic Imaging Experiment 2021 (CASIE21) that collected a regional-scale multichannel seismic reflection dataset to characterize the structure of the CSZ. Interpretations of the top of igneous oceanic crust, megathrust, and Moho allow for regional crustal constraints and on the stratigraphic location of the megathrust. While the mean values for both incoming and subducting regions of the plate show little variation, linear regressions show a generally unchanging crustal thickness for the incoming plate but thinning of the plate with distance from the trench as the plate subducts. We find significant variation in crustal thickness, as great as ~3.5 km, throughout the CSZ from either the three different plates, propagator wakes, or regions of thin crust. In particular, thin downgoing oceanic crust, >1 km thinner than the mean incoming plate, is found beneath the offshore extent of Siletz terrane off Oregon with no major bending-related features found in this region. This also marks a clear change in relative reflection amplitude of the interpreted megathrust. The stratigraphic location of the megathrust is usually found to be near the top of igneous oceanic crust or within the sediment column. Off Oregon, the megathrust step-downs from a sediment-hosted fault near the trench to near the top of igneous oceanic crust at depth. Thinning of oceanic crust under the Siletz terrane may be possible if the megathrust steps down from the sediments into the igneous oceanic crust itself, becoming a basalt-hosted shear zone. This process would alter the megathrust properties, directly impacting the down-dip limit of the seismogenic zone and its behavior.

The study of future risk to coastal flooding requires input from a host of climate models, a robust way to evaluate future storm and sea-level rise scenarios, and in-depth knowledge of the local environments, especially in urban settings. Methods for tackling this problem must run over large ensembles, represent complex physics, and handle the inherent uncertainties. This talk will outline some of these challenges and ways we are attempting to address these issues through both mathematical and computational approaches.

We highlight three different model-(paleo)data comparisons, each with a distinct motivation and approach, in part to deal with the idiosyncrasies of the associated paleoclimate data. In the first, we use high-resolution spatial data for drought over the last millennium to validate the simulation of centennial timescale hydroclimate variability across the Northern Hemisphere. We find that while climate models can simulate realistic variability on these timescales, there are inter-model and -regional differences that must be considered. In the second, we use a single low-resolution record from a sinkhole lake in the Caribbean that is interpreted as reflecting rainfall. Leveraging many simulations of the last millennium from a single climate model we find centennial timescale hydroclimate variability in the Caribbean that is consistent with that in the sinkhole lake record, and other contemporaneous regional records. In the third, we address the question of what coral records can tell us about climate variability. To do so, we drive a coral sensor proxy system model with output from an isotope enabled climate model. We find a surprising amount of spatial heterogeneity in the relationship between these records and climate variability. Nevertheless, some records are likely to provide robust information on large-scale reorganizations of the tropical atmosphere and ocean. Developing paleoclimate data requires substantial and expensive field and laboratory efforts. We view the integration of insights from climate models and paleoclimate data as imperative to best capitalize on these efforts.

The current understanding of such a flow phenomenon is largely rooted in studies of equilibrium boundary layers over and within idealized rough surfaces. Yet, the real world is characterized by flow unsteadiness, three-dimensionality in mean flow, and intricate surface morphologies that defy precise measurement. Under these conditions, the airflow may experience departures from equilibrium with the underlying surface stress, misalignment of shear and strain rates, persistent large-scale secondary circulations, and model predictions may feature a high degree of uncertainty. Fundamental questions remain unanswered regarding structural changes of atmospheric turbulence under such realistic scenarios, challenging our ability to comprehend and predict land-atmosphere interaction across a spectrum of practical situations. In this talk, I will highlight recent efforts in my group devoted.

In this talk, I will apply a computationally efficient tropical cyclone model to downscale a climate model under a modest future emissions scenario. I will show that the projected tropical cyclone hazard is very sensitive to the pattern of ocean warming in the tropical Pacific. Given the discrepancy between the observed and modeled historical pattern of warming in the tropical Pacific, I create an alternate future storyline where the warming pattern resembles that of the observations. In this scenario, near-term tropical cyclone hazard over coastal Asia and the Atlantic basin increases significantly, highlighting the sensitivity of local tropical cyclone hazard to the pattern of warming. * Please note that light refreshments will be served in the atrium from 10:30 AM - 11:00 AM.]]> cos-smanandhar8117284864902024-10-09 15:08:1017284869692024-10-09 15:16:0900eventUnderstanding how tropical cyclone hazards might respond to global warming is important for adaptation.]]>2024-10-17T11:00:00-04:002024-10-17T12:00:00-04:002024-10-17T12:00:00-04:002024-10-17 15:00:002024-10-17 16:00:002024-10-17 16:00:002024-10-17T11:00:00-04:002024-10-17T12:00:00-04:00America/New_YorkAmerica/New_Yorkdatetime2024-10-17 11:00:002024-10-17 12:00:00America/New_YorkAmerica/New_Yorkdatetime<![CDATA[]]>675259675259image<![CDATA[Jonathan Lin Headshot.jpg]]>image/jpeg17284866602024-10-09 15:11:0017284866602024-10-09 15:11:00<![CDATA[A reactive transport model that simulates how rainwater infiltration and chemical weathering impact the evolution of rare earth element fractionation patterns in the critical zone]]>36509
Interest in the rare earth elements (REE) is rising because of their importance in manufacturing micro-electronics, hybrid and fully electric automobiles, medical imaging, permanent magnets, and in wind power generation, among other uses. Because of their ubiquity in the emerging “green economy”, the REEs are likely to become significant environmental contaminants in the future. Of the REEs, the heavy REEs (HREE, i.e., Tb, Dy, Ho, Er, Tm, Yb, Lu) are cosmically less abundant, and hence, commonly of higher economic value than the light REEs (LREE, La, Ce, Pr, Nd, Sm, Eu, Gd). A primary source of the HREEs are ion-adsorption deposits, which are chiefly located in southeast China. These deposits appear to form by low-temperature chemical weathering reactions between meteoric waters and minerals within metaluminous to peraluminous granitoids. The precise biogeochemical processes that form these important deposits have not been completely identified, and the specific geochemical reactions that mobilize, sequester, and fractionate the REEs have not been quantitatively demonstrated. Here, we present a reactive transport model that couples the 1-D advective-dispersive flow equation to an aqueous and surface complexation model for the REEs. Generalized kinetic rate laws for mineral dissolution and precipitation are also included in the model. We investigate the evolution of REE fractionation patterns in groundwaters from a well-studied aquifer using the reactive transport model to gain insights into these processes. The model shows how reactive transport of the REEs affects their fractionation patterns along flow paths, as the composition of groundwater evolves with geochemical reactions in aquifers.

As humanity careens into the uncharted waters of the Anthropocene, we seek novel strategies to modulate the chemistry of our atmosphere. Microorganisms are well-known to produce and consume greenhouse gases and have had outsized influence on the chemistry of Earth’s atmosphere and ocean over the eons. Yet the vast majority of microbial species remain uncultivated, and most microbial proteins, particularly those from marine and subsurface environments, remain uncharacterized. In this talk, I will highlight our lab’s recent studies that integrate environmental omics and laboratory studies of uncultivated marine microbes, including (i) a novel bacterial clade in marine anoxic zones that appear to make their own oxygen from nitric oxide, and (ii) a new type of bacterial proteins from deep subsurface sediments that slow the growth of methane hydrate. These studies inform our understanding of how microbes survive in cold dark anoxic ecosystems and how microbial proteins could play a role in a green economy

The role of ocean dynamics in connecting the open ocean to sea level at the coast currently represents a key knowledge gap in climate science. In this seminar, I’ll talk about how a local current, the Shelf break jet (SBJ), is related to sea level along the U.S. East Coast. I’ll present 7 years of velocity data of the SBJ from the Ocean Observatory Initiative (OOI) Coastal Pioneer Array. Located at the New England shelf break, about 75 nautical miles south of Martha’s Vineyard, the Array has seven site moorings, spread from the shelf to offshore of the shelf break. Each mooring contains, among other instruments, an upward-looking ADCP, which measures three-dimensional velocities throughout the water column. Using spectral analysis, I’ll then show how the SBJ and coastal sea level, based on tide gauge data, are related. Our results show a high correlation on the 1-15 days frequency band, from the South of New England to as far south as the Delaware coast, depending on frequency. Since the 1-15 days frequency band coincides with the frequency variability of storm surges, I’ll finish the talk with some implications for coastal flooding. ]]> arcs-stuweb03117262522272024-09-13 18:30:2717266641302024-09-18 12:55:3000eventAn important driver of regional sea-level change is ocean dynamics. which induces changes related to ocean density and circulation. ]]>2024-09-19T11:00:00-04:002024-09-19T12:00:00-04:002024-09-19T12:00:00-04:002024-09-19 15:00:002024-09-19 16:00:002024-09-19 16:00:002024-09-19T11:00:00-04:002024-09-19T12:00:00-04:00America/New_YorkAmerica/New_Yorkdatetime2024-09-19 11:00:002024-09-19 12:00:00America/New_YorkAmerica/New_Yorkdatetime<![CDATA[]]>674973674973image<![CDATA[Carolina Camargo Headshot.jpeg]]>image/jpeg17262523602024-09-13 18:32:4017262523602024-09-13 18:32:40<![CDATA[virtual seminar]]><![CDATA[Meet James Stringfellow - Your College of Sciences Career Educator!]]>36583 Welcome back, College of Science students!

Pycnocline stratification plays a leading order role in the movement of water between the surface and interior ocean, or ocean ventilation. As a result, stratification shapes the ocean’s capacity for heat and carbon uptake and makes it a key parameter of interest on timescales ranging from paleoclimate to plankton blooms. Part of the challenge in assessing the role of pycnocline stratification in global models is the two-way connection between physical processes at the mesoscale and submesoscale (O(1-100 km)) and stratification. Using idealized high-resolution numerical simulations, we find that the strength of pycnocline stratification influences the formation and evolution of submesoscale structure and the resulting vertical transport of oceanic tracers. Submesoscale anticyclonic eddies efficiently transfer tracer across the base of the mixed layer in reduced stratification conditions. In contrast to previous results with coarser-resolution models, increased stratification does not result in reduced downward tracer flux. We suggest that tracer subduction fluxes reach a “plateau” with changing stratification, with vital implications for our ability to diagnose to predict trends in carbon uptake and storage, particularly in the polar oceans.]]> arcs-stuweb03117256414662024-09-06 16:51:0617256426652024-09-06 17:11:0500eventOcean density stratification is increasing across multiple ocean basins due to a warming surface ocean and increasing sea ice melt. ]]>2024-09-12T11:00:00-04:002024-09-12T12:00:00-04:002024-09-12T12:00:00-04:002024-09-12 15:00:002024-09-12 16:00:002024-09-12 16:00:002024-09-12T11:00:00-04:002024-09-12T12:00:00-04:00America/New_YorkAmerica/New_Yorkdatetime2024-09-12 11:00:002024-09-12 12:00:00America/New_YorkAmerica/New_Yorkdatetime<![CDATA[]]>674859674859image<![CDATA[Dove_headshot.jpeg]]>image/jpeg17256421752024-09-06 17:02:5517256421752024-09-06 17:02:55<![CDATA[EAS Seminar Series – Regime Shift in Secondary Inorganic Aerosol Formation Nitrogen Deposition in the US and Natural Experiment Opportunities]]>36238Da Pan, Assistant Professor, School of Civil and Environmental Engineering, Georgia Tech
Human activities have significantly increased atmospheric levels of Nr, contributing to secondary inorganic aerosol formation and disrupting biogeochemical processes. It is estimated that 40% PM2.5 can be attributed to Nr emissions globally. Meta-analyses indicate that elevated Nr deposition lowers soil carbon decomposition rates, enhancing terrestrial CO2.uptake. However, excessive Nr deposition also leads to adverse effects such as biodiversity loss, soil acidification, and eutrophication. Additionally, increased nitrogen deposition is linked to higher nitrous oxide (N2O) emissions. Balancing the benefits and harmful effects of Nr emissions and deposition requires comprehensive knowledge of its spatiotemporal patterns, composition, and ecosystem impacts. Yet, large-scale and long-term analyses of secondary inorganic aerosol formation and Nr deposition based on model simulations have substantial uncertainties. In this presentation, I will show improved constraints on secondary inorganic aerosol formation using decade-long in situ observations from multiple monitoring networks across the United States. I will discuss a shift in the secondary inorganic aerosol formation regime between 2011 and 2020, making rural areas less sensitive to changes in ammonia concentrations and shortening the effective atmospheric lifetime of reduced forms of Nr. This leads to potential increases in reactive nitrogen deposition near ammonia emission hotspots, which provides unique opportunities to evaluate ecosystem responses and the interaction between carbon and nitrogen cycles. Finally, I will identify locations that have experienced significant Nr deposition changes and possess comprehensive atmospheric and ecological observations for potential natural experiments.

In this talk, I will begin by presenting results from lidar topography, structural-geomorphic mapping, and paleoseismic trenching to reveal evidence for a previously unrecognized Quaternary-active fault network in the forearc of the northern Cascadia subduction zone on Vancouver Island, Canada.
Using compiled GNSS, geologic, and paleomagnetic data, I will argue that these faults accommodate active oroclinal bending of the entire Cascadia margin due to along-strike changes in subduction zone obliquity and local slab geometry.
I will suggest that this oroclinal bending is related to the broad concave- outboard trench geometry observed across the Cascadia and Southern America subduction zones. Finally, I will discuss how new results from a global compilation of forearc faults suggest subduction zone obliquity may play a key first-order role in forearc rotation and forearc faulting across the world’s subduction zones.
This seminar presents a study on a newly identified active fault network in the northern Cascadia subduction zone, suggesting that subduction zone obliquity drives forearc deformation and faulting. The study also emphasizes the global impact of subduction zone obliquity on forearc rotation.

Restrepo]]>34732 Abstract: Can waves transport significant amounts of ocean heat and tracers great distances, thus affecting Earth’s climate? This question was the basis for a project which culminated in the wave-driven circulation model and a concrete answer to how this process takes place. Moreover, the project also showed that wave-generated transport was most intense in the nearshore, leading to an examination of the impact of wave-generated transport on important nearshore processes, such as movement of ocean pollution and nutrients in coastal areas. In my talk, I will describe how the vortex-force conceptualization led to the formulation of the model and a theoretical basis for how waves and currents interact at scales larger than the wave scales.
The ever-present noise in natural processes and in the instruments used to measure them motivated me to create computational methods that could combine models, such as the wave circulation model and models for climate and weather, and observations in a probabilistic framework to make better predictions. While optimal estimate methods for linear problems existed, the focus of my work was instead on developing algorithms that could handle the more common noisy nonlinear processes in the geosciences. I will detail some of the strategies I used to create methods and algorithms that assimilate observations, rational models, and machine-learned data-driven constructs to improve forecasts in time-dependent problems, arising in the geosciences and beyond.

Affiliation: Florida State University
We here introduce a climate feedback kernel, referred to as the “energy gain kernel” (EGK). EGK allows for separating the net longwave radiative energy perturbations given by a Planck feedback matrix explicitly into thermal energy emission perturbations of individual layers, and thermal radiative energy flux convergence perturbations at individual layers resulting from the coupled atmosphere-surface temperature changes in response to the unit forcing in individual layers. The former is represented by the diagonal matrix of a Planck feedback matrix and the latter by EGK. Elements of EGK are all positive, representing amplified energy perturbations at a layer where forcing is imposed and energy gained at other layers, both of which are achieved through radiative thermal coupling within an atmosphere-surface column.
Applying EGK to input energy perturbations, whether external or internal due to responses of non-temperature feedback processes to external energy perturbations, such as water vapor and albedo feedbacks, yields their total energy perturbations amplified through radiative thermal coupling within an atmosphere-surface column.
As the strength of EGK depends exclusively on climate mean states, it offers a solution for effectively and objectively separating control climate state information from climate perturbations for climate feedback studies. Given that an EGK comprises critical climate mean state information on mean temperature, water vapor, clouds, and surface pressure, we envision that the diversity of EGK across different climate models could provide insight into the inquiry of why, under the same anthropogenic greenhouse gas increase scenario, different models yield varying degrees of global mean surface warming.

Physicochemical properties such as the viscosity of SSA are understudied but can affect gas-particle interactions and heterogeneous reaction kinetics, and thus the chemical lifetimes of pollutants in SSA. In this talk, I will discuss three major research thrusts in my group: (1) measurement and modeling of the biological and molecular drivers of SSA viscosity, (2) quantitative analyses of toxic plastic additives and other chemical pollutants in SSA sampled in coastal San Diego, and (3) the effects of chemical aging and particle viscosity on the lifetimes of toxic plastic chemical residues in model SSA matrices.

The Permian-Triassic (PT) extinction also known as the Great Dying Event is regarded as the largest extinction in Earth’s history. While a number of hypotheses have been proposed to explain the cause, tempo, and severity of the mass extinction they are often contradictory. These hypotheses are based on data from a variety marine and terrestrial PT sections distributed globally. The mass extinction research community set a Global Stratotype Section and Point (GSSP) for each mass extinction. The GSSP section is considered the most accurate, continuous, and reliable section for studying a mass extinction. In the case of the PT extinction, the GSSP section is the marine (Paleo-Tethys) Meishan section located in Changxing County, Zhejiang Province, South China. Despite the selection of this section as the GSSP, many other marine PT sections are paleontologically, sedimentologically, and geochemically distinct and, in some cases, more complete (e.g. Serbia and Hungary).
In the presentation, we look at the geochemical signatures of two PT Sections, Serbia and Hungary that present the Western Tethys Ocean to understand the response and tempo of the PT Extinction. Although, there are similarities to GSSP Meishan, there are vastly different geochemical responses inferring that the PT Extinction is more complex than previously thought.
