Paleontology meets social justice: who says we can’t make progress? Examples from new and planned virtual and actual exhibits at the UC Museum of Paleontology
About Dr. Lisa White
Geologist and Director of Education and Outreach at the University of California Museum of Paleontology; Fellow of California Academy of Sciences; mentoring and promoting opportunities for geoscience majors; public outreach has been a major part of her career; Chair of the Geological Society of America Committee on Minorities and Women in the Geosciences; Project Director and PI of the SF-ROCKS (Reaching Out to Communities and Kids with Science in San Francisco) to bring geoscience education to high school students and teachers in San Francisco; Co-PI on the NSF FIELD program (Fieldwork Inspiring Expanded Leadership and Diversity) to create more accessible, culturally sensitive, and inclusive field experiences, particularly for students underrepresented in the geosciences.
DeFord Lecture Series
Since the 1940’s, the DeFord (Technical Sessions) lecture series, initially the official venue for disseminating EPS graduate student research, is a forum for lectures by distinguished visitors and members of our community. This is made possible through a series of endowments.

Title: How to make new seafloor with detachment faults for company
Abstract: At slower-spreading ridges, plate separation is often partly accommodated by slip on long-lived detachment faults, commonly forming corrugated domes called oceanic core complexes. However, the mechanics of this process, and the subsurface structure and connectivity of oceanic detachments, remain uncertain. I will present the results of repeat passive microearthquake surveys conducted in 2014 and 2016 over a pair of oceanic detachments on the Mid-Atlantic Ridge near 13°N. The two ocean bottom seismograph networks provided dense spatial coverage of the two adjacent detachment faults, and the intervening ridge axis. Although both detachments exhibited high levels of seismicity, they are separated by a ~8–10 km wide aseismic zone, indicating that they are mechanically decoupled. Significant changes in the patterns of seismicity between the two surveys are observed implying that stress accumulation and release varies on years-long cycles.
UTIG Seminar Series: Tanner Mills, UTIGApril, 19 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Tanner Mills, Postdoctoral Fellow, University of Texas Institute for Geophysics Host: Peter Flemings Title: Predicting greenhouse gas fluxes to the atmosphere from thawing permafrost Abstract: Arctic permafrost is thawing at rapid rates, which threatens to expose large stores of soil organic carbon to microbial degradation. As microbes utilize this carbon source, they produce greenhouse gasses (GHGs; CO2 and CH4) that can be emitted to the atmosphere and act as a positive feedback during future global temperature increases. While the permafrost carbon feedback has received much attention in the literature, little is known about the multiphase flow properties and the temperature dependence of microbial GHG production rates in thawing permafrost, both of which are essential for predicting GHG emissions from permafrost in the future. Flow experiments of synthetic and natural permafrost specimens under frozen conditions and incubations of permafrost samples are being performed to better understand the effective and relative permeabilities and GHG production rates of thawing permafrost soils. These data will be integral in providing new source terms for permafrost and global carbon models. |
Master\'s Thesis PresentationsApril, 19 2024Time: 2:00 PM - 5:00 PMLocation: JGB The Master of Science (MS) degree at the Jackson School of Geosciences is considered to be the professional degree for a career in the Geosciences. This degree is the foundation for students pursuing employment in the petroleum industry, environmental and hydrogeological fields, state and federal government agencies, and other related geoscience fields. Some students also use the MS degree as preparation for pursuing a Ph.D. The Energy & Earth Resources Interdisciplinary program provides the opportunity for students to prepare themselves in management, finance, economics, law and policy leading to analytical and leadership positions in resource-related fields. The private sector and government organizations face a growing need for professionals that can plan, evaluate, and manage complex resource projects, commonly international in scope, which often include partners with a variety of professional backgrounds. As requirements for these degrees, students must present a professional talk on Master\'s Thesis Presentations. |
Hot Science - Cool Talks: \"Humans vs AI\"April, 19 2024Time: 5:30 PM - 8:15 PMLocation: Burdine 106 Advancements in AI have unleashed astonishing capabilities, but it is not magic. Peter Stone reveals his insights into cutting-edge AI and robotics and explores how they may reshape our world.

UTIG Seminar Series: Cornelia Rasmussen, UTIGApril, 26 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Cornelia Rasmussen, Research Associate, University of Texas Institute for Geophysics Host: Krista Soderlund Title: The Emerging Field Of Position-Specific Isotope Analysis: Applications in chemical forensics, exobiology, geo- and environmental sciences Abstract: Complex organics can be found all over our solar system and within each living thing on our planet, be it as part of its physiology or as a contaminant. 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. |
