“Wave-Theoretic Imaging and Inversion of Time-Lapse Seismic Wavefields”
Abstract:
Time-lapse seismic monitoring of reservoir fluid flow and other time-variant subsurface phenomena can be achieved with active and/or passive source seismology. Conventionally, active-source 4D seismic monitoring of reservoir production changes in saturation, pressure, and geomechanical effects is
conventionally done via prestack time migration analysis of the time-lapse wavefields. Instead, we present new developments that demonstrate the benefits of using the full time-lapse wavefields more accurately, for example via 4D prestack depth migration (4D PSDM), 4D wave-equation migration velocity analysis (4D WEMVA) and 4D full waveform inversion (4D FWI). These new developments provide an opportunity for more accurate imaging of complex scattered 4D wavefields, and also the possibility to monitor very weak signals using 4D coda waves such as in gas depletion reservoirs.
Passive monitoring of natural or induced seismicity in the subsurface typically involves seismic data recorded from a few sparse sensor locations, picked event arrival times, and triangulation to determine microseismic event source locations. This conventional approach to passive seismic monitoring has remained relatively unchanged for the past 100 years. Instead, we present new developments that
demonstrate an opportunity for significant improvements in passive seismic imaging and monitoring by using large dense (possibly permanent) buried receiver arrays that record the full induced seismicity wavefields, and by using full wavefield imaging techniques applied to passive array seismic data and ambient noise fields.

“Rheological Properties of the Mantle Lid Beneath the Mojave Region”
Abstract:
Recently deformed mantle peridotite xenoliths derived from Moho depths constrain the geothermal gradient, stress magnitude, viscosity, and degree of localization in the upper mantle within the tectonically active Mojave region of California. Microstructural observations and water content measurements in the xenoliths indicate that upper mantle deformation is accommodated by dislocation creep of olivine with ~250 ppm H/Si. Differential stresses measured using olivine paleopiezometry are 12-15 MPa, several tens to hundreds of MPa less than stresses estimated for the gabbroic lower crust and the brittle upper crust. Similarly, a calculated mean viscosity of 5 x 1019 Pa-s for the uppermost mantle is approximately two orders of magnitude less than estimated for the lower crust, consistent with recent models of the Mojave region based on postseismic relaxation following the Landers (1992) and Hector Mine (1999) earthquakes. These results confirm that the Mojave region fits a `creme brulee’ model of lithospheric rheology structure, in which the peak stress resides in the crust, rather than within the lithospheric mantle. Temperatures and pressures recorded in the xenoliths indicate a high geothermal gradient of at least 825°C at the Moho, which may explain the regional weakness of the mantle lid. Strain rates calculated for the uppermost mantle using the xenolith data and olivine flow laws for wet dislocation creep, are at least four times higher than bulk strain rates estimated across the central Mojave region from GPS-constrained surface velocities. This implies either that faults at the eastern border of the Eastern California Shear Zone persist through the seismogenic zone and retain their identities as narrow ductile shear zones into the mantle beneath the Moho; or alternatively, that a zone of high strain just below the Moho accommodates differential motion of upper and lower lithospheric layers.

“The Role of Water in Glacier Dynamics in Greenland and Antarctica”
Abstract:
Glaciers are made up of ice that flows under its own weight. Glaciers flow in two main ways: one is internal deformation where the body of the glacier deforms and ice flows relatively slowly. The other is glacier sliding where the ice slides on a layer of water and water-saturated sediments. Our understanding of the glacier-sliding mode of ice flow is incomplete. Recent results suggest that supraglacial lakes draining to the bed of the Greenland Ice Sheet contribute to speedup of the ice flow. In addition, ocean warming leads to increased melt of floating ice shelves. The loss of these ice shelves also leads to speedup of the ice flow. My research is related to the conditions at the base of the ice sheet and attempts to better model these interactions of water and ice flow.

“Adventures in Anisotropy: Constraints on Mantle Dynamics from Seismological Observations”
Abstract:
Observations of seismic anisotropy provide constraints on the pattern of mantle flow and represent one of the best tools available for studying mantle dynamics. I will discuss methods for observing anisotropy in the Earth’s mantle and how we interpret these observations in terms of mantle deformation. I will describe new and often surprising observations of anisotropy in key parts of the mantle, including in subduction zones and in the D” layer at the base of the mantle, and discuss the implications for our understanding of how the mantle works as a dynamic system.

“The September 5, 2012 M 7.6 Nicoya Earthquake, Costa Rica: a Natural Lab for Large Subduction Zone Earthquakes”
Abstract:
The 2012 Nicoya Earthquake was extremely well monitored with networks of broad-band seismometers and continuous GPS. Changes in coastal geomorphology related to the earthquake were also well-measured by surveys before and after the event. Most of these data are publicly available. Models that include pre-event slow slip and post-seismic slip are now being developed and compared to co-seismic slip and late stage interseismic locking, allowing a detailed picture of strain accumulation and release. These models suggest that detailed monitoring of strain accumulation in the critical offshore region could be helpful at forecasting the size of future subduction zone earthquakes.

UTIG Seminar Series: Melisa Diaz, The Ohio State UniversityMarch, 29 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Melisa Diaz, Assistant Professor, The Ohio State University Host: Benjamin Keisling Title: Biogeochemistry of a Greenland Ice-Marginal Lake Abstract: Due to polar amplification, nearly every glacier in Greenland has thinned and/or retreated in recent decades. The meltwater generated from these glaciers can take several paths, ultimately discharging into coastal waters or stored in closed-basin lakes. Ice-marginal lakes are a common but poorly understood feature in many glaciated regions, including Greenland. The lakes receive freshwater input from a combination of subglacial, supraglacial, terrestrial and meteoric sources, and a subset periodically drain, resulting in the rapid discharge of large volumes of water downstream (glacial lake outburst floods – GLOFs). In the case of drainages under adjacent marine terminating glaciers, GLOFs can deposit large amounts of sediment, nutrients, and freshwater directly into coastal waters and fjords. Lake Tininnilik, a large (~40 km2) ice-marginal lake that forms along Saqqarliup Glacier in west Greenland, drains ~2 km3 on quasi-cyclic decadal timescales into Saqqarleq Fjord to the north. For this talk, I will discuss the first comprehensive biogeochemical analysis of Lake Tininnilik and its potential influence on coastal primary productivity, including its major and minor nutrient stoichiometry and microbial composition. As the climate continues to warm, GLOFs are expected to become more frequent in Greenland. Therefore, it is imperative that we understand how these events can impact coastal community resilience. |

Speaker: Crispin Little, Professor, School of Earth and Environment, University of Leeds Host: Rowan Martindale Title: Biotic response to environmental perturbations in the Pliensbachian and Toarcian stages of the Lower Jurassic Abstract: The Lower Jurassic period was characterized by instability in global climate, with alternating greenhouse and icehouse states, and episodes of widespread oxygen depletion in the shallow marine environment. These episodes of oxygen depletion are marked by frequent intervals of increased organic carbon preservation in shallow marine sediments. The Pliensbachian stage of the Lower Jurassic was characterised by significantly cooler global temperatures than the preceding Sinemurian, and the following Toarcian stages, and ended with an extinction event (notably for ammonites) at the Pliensbachian-Toarcian boundary (Pl-To) ca. 184.2 Ma. About one Myr later the Toarcian Oceanic Anoxic Event (T-OAE) is characterized Corg rich black shale successions, particularly well developed in sedimentary basins in NW Europe, which display a negative ?13Corg excursion of -5 to -6‰, lasting 0.5 to 1.5 Myr. This excursion has been tied to a disruption of the global exogenic carbon cycle, but the ultimate source of the injected 12C is a matter of debate, with suggestions including methane hydrates, thermogenic methane produced by volcanism in the Karoo-Ferrar Large Igneous Province (LIP), wetlands, and permafrost destabilisation. The onset of the T-OAE in many (but importantly not all) sections is intimately linked to an extinction event that especially impacted the marine benthic macrofauna, but left the nekton largely unaffected. The recovery from this event is not well studied, but in one site, the Cleveland Basin of North Yorkshire, UK, although species richness recovered markedly as soon as environmental conditions ameliorated, other metrics of functional diversity and community structure did not attain pre-extinction levels until much later, some five million years after the extinction event. The talk will be of interest to those working on macroevolution, paleontology, and the effect of large scale climate change on marine ecosystems. |

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. |
