How high was last interglacial sea level?
Dr. Jacky Austermann, Columbia University
Abstract: The Last interglacial (~125ka) was 0.5-1.5 ºC warmer than today, making it an interesting natural experiment for how ice sheets respond to modest warming. In this talk I will first describe past estimates for Last interglacial sea level and corresponding polar ice retreat before presenting our new assessment from sea level data in the Bahamas. I will show our field evidence and describe how we can leverage the spatial extent of the data to constrain the contribution of glacial isostatic adjustment to past sea level. Based on these data, we find that Last Interglacial sea level very unlikely exceeded ~5m, which is below the current estimate from the IPCC. Next, I will present new Last Interglacial sea level data from northwest Europe, and argue that these observations predominantly constrain the contribution from the Antarctic ice sheet during the Last interglacial. Combining both results (from the Bahamas and northwest Europe) allows us to not only produce a new time-varying estimate of Last Interglacial sea level, but also partition this melt between Greenland and the Antarctic ice sheet. I will end by speculating what these new results mean for future sea level rise.

Title: Diversity, Equity and Inclusion in the Geosciences: Where Are We Now?
Abstract: The geosciences are among the least diverse STEM fields, with a need for concerted action on various fronts. With the events of 2020, including the pandemic which disproportionately impacted women and communities of color, and the racial justice movement, as we return to work we need to take stock of where we are now in the DEI space and what we can do to promote inclusion. This session will provide insights and guidelines on advancing DEI in the geosciences, with a focus on the events of the past year and what they mean for DEI efforts.

Seismogenic Features of the Snyder Seismic Zone, Northwestern Texas
Earthquake activities in the greater Permian Basin have significantly increased since 2008. Over time, seismic events were unevenly distributed throughout the basin and often occurred in a number of seismic zones which may have disclosed concealed seismogenic structures. Among them, the Snyder area of northwest Texas has a significant seismicity rate, second only to that of the Delaware Basin, a subunit of the greater Permian Basin. A recent study has investigated the concealed seismogenic structures in the Snyder area using three main approaches: (1) relocated and delineated seismicity, (2) performed waveform moment tensor inversion to determine earthquakes’ source mechanisms, as well as (3) conducted stress inversion to assess the stress state. In this presentation I will present the study results. Results show that seismicity are concentrated in the basement-top. The collective pattern of source mechanisms presents a fault system comprising a mix of strike-slip and normal faults. The overall geometry of seismicity distribution illustrates an apparent northeast-to-southwest lineation, aligning with the direction of maximum horizontal stress. This study has further identified several seismogenic cycles in 2017-2021. Results also demonstrate a temporal variation of b-value, which should be associated with the perturbation of effective normal-stress along the preexisting fault planes during the earthquake cycles. It also presents a series of foreshock-mainshock-aftershock sequences that seemingly resemble tectonic-like seismicity. All of which suggest that seismicity in the Snyder area involves re-activation of basement-rooted faults.

With more than 500,000 objects floating in space and only about 2,000 functioning, space junk is growing exponentially. When these objects stop working, they drift aimlessly into the cosmos. These rogue bits of metal and space debris pose a danger to the technologies we rely on and to the future of space exploration. Dr. Moriba Jah examines what we can do to make space safe, secure and sustainable in the long term.
After joining the U.S. Air Force, Dr. Jah discovered aviation and eventually pursued aerospace engineering. He came to the University of Texas by way of the Air Force Research Laboratory and NASA’s Jet Propulsion Laboratory prior to that, where he was a Spacecraft Navigator on Mars missions. He is the director for Computational Astronautical Sciences and Technologies at UT. His research focuses on identifying and tracking space objects.
The event will be streamed live through our Facebook and YouTube channels and will include a Q&A session. Additional information is available at www.hotsciencecooltalks.org.

Rheological heterogeneity in deep continental crust: Examples from the Rocky Mountains, the Canadian Shield, and the European Alps
Dr. Kevin Mahan, University of Colorado
Abstract: This presentation will highlight three examples of rheological heterogeneity recorded in exhumed exposures of deep continental crust. The first two are examples where lithological contrasts influenced the rheological behavior of kilometer-scale ductile shear zones, and the third is an example of mechanical heterogeneity in the form of initial fractures that evolved to ductile shear zones. While the examples vary widely in scale and tectonic setting, a common observation is that heterogeneity (lithological and mechanical) and fluid availability (and fluid-rock interaction) played critical roles in promoting active deformation mechanisms and transient ductile and brittle behavior.
The Paleoproterozoic Hell Roaring Creek shear zone is a 3 km wide, steeply dipping amphibolite-facies structure exposed in the northern Madison Range of southwest Montana (~25 km paleodepths). Mineral assemblages and local evidence for metasomatism suggest deformation developed under relatively wet conditions. Stretching lineations within the shear zone have a bimodal geometry, with nearly down-dip orientations in most lithologies but shallowly plunging orientations in the most quartz-rich lithologies. Dextral shear sense indicators are consistently observed on subhorizontal surfaces. Observations within and adjacent to the shear zone suggest that the steep fabric elements are at least partly inherited from an earlier episode of deformation and were enhanced during subsequent shear zone activity. Thus, the shear zone exhibits strain partitioning during transpression due to rheological contrast among lithologies and heterogeneity from inherited structures.
PseudotachylyteThe Paleoproterozoic Cora Lake shear zone in the western Churchill Province of the Canadian Shield is a several km wide zone of granulite- to upper amphibolite-facies mylonite which hosts synkinematic pseudotachylyte (~30-25 km paleodepths). Limited evidence for hydrous fluids suggest relatively dry conditions. The shear zone is localized at a major lithological and terrane boundary, with the pseudotachylyte network centered on the more intensely deformed, finer-grained ultramylonitic core. We conclude that episodic brittle failure during lower-crustal ductile shear was most likely due to local stress amplification from a relatively common type of km-scale lithological heterogeneity.
Fracture systems in otherwise homogeneous granites in the Alps and in meta-gabbronorite dikes in Montana systematically evolved into outcrop-scale ductile shear zones under amphibolite- to eclogite-facies conditions, with strong influences from locally fluxing aqueous fluids. The interpreted shear zone evolution involved (1) initial strain localization by nucleation on pre-existing, or in some cases nearly co-eval, fractures that focused fluid infiltration, (2) grain-size reduction by microfracturing, dislocation creep, and synkinematic metamorphic reactions driven by chemical potential gradients, and (3) a switch to grain-size sensitive granular flow accommodated by fluid-assisted diffusion in ultramylonite.

Large scale geological storage of hydrogen to support Net Zero
To meet the global commitments for net zero carbon emissions our energy mix must transition from fossil fuels. Hydrogen is gaining increasing recognition as a low carbon energy option to support this energy transition. Hydrogen is considered a low-carbon substitute for fossil fuels to decarbonise domestic and industrial heat, power generation and heavy-duty transport. It can also promote increased renewable energy uptake by acting as an energy store to balance supply and demand.
For hydrogen to be deployed at the scales required for net zero, we will need access to large-scale geological storage. Our initial studies show that the required storage capacity exists in depleted gas fields within the UK North Sea. This talk will present an overview of the most recent findings from the EPSRC funded HyStorPor project, working to establish the feasibility of storing hydrogen in underground porous reservoirs. The talk will cover the results of our research into the key biological and chemical reactions between the reservoir rocks, formation fluids and injected hydrogen that could compromise the storage complex; the key flow processes that influence hydrogen migration and trapping during injection and withdrawal and our findings from reservoir simulations to estimate what volumes of hydrogen can be stored and recovered from storage sites, with a particular focus on the role of the cushion gas.

A seminar from the Center for Planetary Systems Habitability
Title: Mass measurements and rescue of planets using a fully dedicated Australian observatory
Speaker: Rob Wittenmyer, Professor, (MINiature Exoplanet Radial Velocity Array) MINERVA-Australis Observatory, University of Southern Queensland, Australia
Abstract:
NASA’s Transiting Exoplanet Survey Satellite (TESS) has identified more than 4500 planet candidates in its first three years of operation. Spectroscopic follow-up of these planets remains a bottleneck, with more than 95% of candidates awaiting confirmation. MINERVA-Australis is the only southern hemisphere observatory wholly dedicated to the detailed follow-up of TESS planets. Being fully robotic, we have been unaffected by Covid-19 closures. We have contributed to the confirmation of 30 planets to date — nearly 20% of all TESS confirmed planets. I present mass measurements and system parameters for several new planets using MINERVA-Australis radial velocities. I also describe our new photometric capabilities, aiming to validate small TESS planets and to rescue planets from ephemeris erosion. MINERVA-Australis is accessible via NSF NOIRLab proposals, and the US community is highly encouraged to take advantage of its spectroscopic and photometric resources.

However, different processes can lead to the formation of chemical identical molecules. This makes answering a number of scientific questions challenging. One example is distinguishing between biotic and abiotic molecules, hence hindering life detection on early Earth but especially on other planetary bodies, such as on Mars, Titan, Enceladus and on meteorites where organics have been detected. Moreover, tracing molecules as they move through the environment can be demanding, yet is essential in studying the flow of organic molecules as well as correlating pollutants with their source. Novel tools to address these challenges are currently being developed. Especially, the emerging field of position-specific isotope analysis is beginning to grant access to the unique intramolecular carbon (13C/12C) isotope fingerprint preserved in complex molecules. This fingerprint can be applied in various scientific disciplines, ranging from forensics to exobiology, geo- and environmental sciences, including geo health. Nuclear magnetic resonance spectroscopy (NMR) has the potential to become a key player in this research area, as it allows the analysis of organics within complex mixtures, all without the need to fragment the molecule into single carbon units or the combustion of the molecule of interest. We have been developing several NMR tools that allow us to investigate the intramolecular carbon isotope distribution within various molecule classes and to test the central hypothesis that the position-specific carbon isotope distribution within complex organics depends on a molecule’s source and formation history. |
