DeFord Lecture: Melissa Kemp

January, 21 2021

Time: 4:00 PM - 5:00 PM

Biodiversity in the Anthropocene: a paleobiological perspective

About Dr. Melissa Kemp (UT Austin)
Impact of Sea level change and colonization on Caribbean lizards; how extinction, diversification, and colonization are shaped by environmental perturbations; integration of macroevolutionary theory with paleobiology, ecology, and conservation biology by combining field, laboratory, and quantitative methods.

DeFord Lecture Series
Since the 1940\'s, the DeFord (Technical Sessions) lecture series, initially the official venue for disseminating DGS 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: The transient and intermittent nature of slow slip

Abstract: Slow, aseismic slip (such as slow slip and surface creep) is now recognized as the glue at tectonic plate boundaries that holds the earthquake cycle together. Since the first observations of surface creep along the San Andreas plate boundary more than 50 years ago, advances in geophysical instrumentation and innovative observational approaches have revealed that faulting at major plate boundaries covers a broad spectrum of slip modes, from fast earthquake ruptures to intermittent slow slip.

Today, the continuous GPS record and satellite imagery reveal the jerky, intermittent nature of aseismic slip. The pattern that is emerging suggests that slow slip at plate boundaries and surface creep on major transform faults is not a steady, continuous process as once thought, but is rather a complex spatiotemporal cluster of interacting aseismic transients. Aseismic slip rate variations have now been observed at all temporal scales, from seconds to decades. These new observations suggest slow slip is much more similar to earthquake slip than previously acknowledged, with strong implications on our understanding of the dynamics of active faults. These new observations call for new families of models with much broader dynamics that are able to reproduce the observed rich spectrum of slow slip.

DeFord Lecture: Jennifer McIntosh

UTIG Seminar Series: Emily Eidam, UNC at Chapel Hill

January, 29 2021

Time: 10:30 AM - 11:30 AM

Speaker: Emily Eidam, University of North Carolina at Chapel Hill

Host: John Goff

Research Areas: Fluvial and coastal sediment transport dynamics

LEO Seminar Series: Liz Catlos and Ginny Catania

February, 03 2021

Time: 1:00 PM - 2:00 PM

The purpose of LEO is to create a more inclusive and educated community within the JSG by sharing and listening to each other’s stories. Speakers will interview each other and talk about why they are involved in Diversity, Equity, and Inclusion efforts and the heart behind their work. By learning more about why individuals are involved in DEI, we will broaden our understanding of the impacts the JSG is making on students, faculty, staff, and greater society. Taking initiative to get to know each other, ask questions, and Listen to Each Other is a skill that will propel us further to be leaders in the geosciences.

DeFord Lecture: Kathleen Johnson

February, 04 2021

Time: 4:00 PM - 5:00 PM

About Dr. Kathleen Johnson (University of California Irvine)

Speleothem researcher that specializes in reconstructing Asian monsoon and California coastal drought dynamics; utilizes instrumental climate data, paleoclimate data and isotope-enabled climate models to investigate the spatial and temporal patterns of natural climate variability, calibrate paleoclimate proxy data and investigate mechanisms of past climate variability.
