EGD Colloquium: Roland Gritto
Roland Gritto What to Expect Seismic tomographic imaging relies on P-wave and S-wave velocities to delineate geological subsurface structures. In contrast, the ratio between seismic P-wave and S-wave velocities (Vp/Vs) is more sensitive to fluid saturation. Vp/Vs-ratio has been utilized in numerous studies to distinguish liquid from gaseous fluids in the Earth’s subsurface. Studies include seismic exploration of gas and oil reservoirs, imaging of fluids in fault zones, investigations of volcanic regions to delineate and track movement of liquids (melt)…

Experimental Insights into the Seismic Response of Single Fractures
Harrison Lisabeth, Postdoctoral Research Fellow Speaker Bio Harry Lisabeth is currently a Postdoctoral Research Fellow in the Energy Geosciences Division at Lawrence Berkeley National Laboratory (LBNL). He received AB’s in Geological Sciences and Literary Arts from Brown University in 2010 and a Ph.D. in Geology from the University of Maryland, College Park in 2016. His graduate work focused on the effects of chemistry on rock deformation. From 2016 to 2018 he was a Postdoctoral Research Fellow at Stanford University working…

Deformation of Granite with Crack-Seal Veins Under in situ Stress Conditions
Dr. Junlong Shang, Postdoctoral Research Fellow What to Expect Granite is one of the most common rocks in the Earth’s crust. Because of its favorable mechanical, hydrogeological, and geochemical properties, granite formations have been frequently involved in the subsurface energy-related activities such as long-term disposal of radioactive waste, and underground storage of oil, gas, and water. Granite is heterogeneous since it is made up of various mineral aggregates (basically quartz, feldspar, and mica) with distinctive texture and chemical compositions. The…

Climate Brown Bag: Forest Water Use, Resilience, and Mortality Under Climate Variations and Change
Yanlan Liu What to Expect Forest response to hydro-climatic stresses contributes to large variations of gas and energy exchanges between the biosphere and the atmosphere. Severe stresses during droughts have also led to widely observed forest mortality across the globe. Limited understanding of forest dynamics in response to climate variations and change is among the dominant sources of uncertainty in climate projections. Based on mechanistic models, Yanlan will discuss how water stresses from both the soil and the atmosphere regulate…

Experimental Constraints on Hydrothermal Circulation in Mid-Ocean Ridges
Nick Pester, Research Scientist What to Expect Magmatic activity beneath the seafloor drives hydrothermal circulation, promoting heat transfer and chemical exchange between newly forming ocean crust and seawater. This process results in the seafloor discharge of fluids that have been compositionally modified, exerting a major control on the chemistry of seawater. Hydrothermal venting also creates large metallic mineral deposits, and provides chemosynthetic energy for primitive microbes. A key problem in studying the chemical evolution of seawater into hydrothermal fluid is…

A Framework for Climate Change Adaptation Planning of California’s Electricity-Water Nexus
Julia Szinai Speaker Bio California’s electricity system is closely linked to its water system: 19% of electricity consumption relates to water pumping, conveyance, treatment, and end-use, and 15% of electricity generation is from hydropower. Climate change impacts—including higher temperatures, shrinking snowpack, and more frequent droughts—will exacerbate these interdependencies. Further, climate adaptation actions in the water sector can affect the electricity sector because new water supplies are usually energy intensive. However, it is unclear from prior assessments which climate impacts across…

Geophysical Information Flow Networks: Causal Dependencies in Multivariate Dynamical Systems
Praveen Kumar Speaker Bio Prof. Praveen Kumar holds a B.Tech. (Indian Institute of Technology, Bombay, India 1987), M.S. (Iowa State University 1989), and Ph.D. (University of Minnesota 1993), all in civil engineering, and has been on the Univ. of Illinois faculty since 1995. He is also an Affiliate Faculty in the Department of Atmospheric Science; Institute of Sustainability, Energy, and Environment; National Center for Supercomputing Applications; Carle Woese Institute for Genomics Biology; and Center for Digital Agriculture. His research focus…

Pore Scale, Darcy Scale, Off-Diagonals: Reactive Transport at the Crossroads
Dr. Carl I. Steefel Department Head of Geochemistry What to Expect Reactive transport in the Earth and Environmental Sciences is at a crossroads today. The discipline has reached a level of maturity well beyond what could be demonstrated even 15 years ago. This is shown now by the successes with which complex and in many cases coupled behavior have been described in a number of natural Earth environments, ranging from corroding storage tanks leaking radioactive Cs into the vadose zone…
