“Measurements of Slow Slip Phenomena in Cascadia and Parkfield Recorded by Plate Boundary Observatory Strainmeters ”
Abstract:
The Plate Boundary Observatory (PBO), operated by UNAVCO, is the geodetic component of the NSF funded Earthscope program. Its purpose is to record the full spectrum of deformation processes that accommodate strain accumulation and release across the Pacific-North American plate boundary in the western US. Enabling investigation of the role aseismic strain transients play in plate boundary deformation was one of the stated goals of PBO and to accomplish this, strainmeters were included in the observatory. Their role is to capture transients the size and duration of which would render them undetectable by GPS and seismology. Between June 2005 and October 2008 75 borehole and 6 long-baseline laser strainmeters were installed in targeted regions with specific questions in mind, e.g., Episodic Tremor and Slip (ETS) events in Cascadia, slow slip events along the Parkfield and San Juan Bautista segments of the San Andreas and strain accumulation in the Anza seismic gap near the San Jacinto fault. Four were installed on Mt St Helens and five in Yellowstone for volcano deformation studies. Since completion of the network PBO strainmeters have provided unprecedented temporal resolution of strain pulses that evolve over minutes, e.g., nanostrain-level creep events on the central San Andreas, out to measurements of transients on the order of a 100 nanostrain over weeks during Episodic Tremor and Slip events along the Cascadia Subduction Zone.
PBO boreholes are multi-instrumented sites containing combinations of strainmeters, seismometers, pore pressure sensors, and meteorological instrumentation. Volcanic sites also include tiltmeters. Raw data are available to the research community in SEED format from IRIS; processed data are available from UNAVCO within 24 hours. As of April 2015 more than 1 TB of PBO BSM raw data and products have been delivered to users and strainmeter data products have been downloaded by more than 1,400 unique users. This presentation will include details of installing and operating the PBO strainmeter network, the steps required to process and isolate tectonic transients and highlight some of the unique signals these instruments have recorded particularly in Cascadia and Parkfield over the past 10 years.

“Explosive Volcanism on Mars: Chronology, Sources, and Applications to Human Exploration”
Abstract:
The Medusae Fossae Formation is a voluminous deposit of fine-grained material stretching across thousands of kilometers along the Martian equator. Thought to be either an ignimbrite deposit or a volcanic ash sheet, the deposit represents one of the most enigmatic and unusual geological formations on Mars. This seminar will discuss the history of explosive volcanism on Mars and then focus in on the Medusae Fossae Formation, how it may have been formed, how it has been modified since its formation, and how it could serve as a scientific and industrial resource for future human missions to Mars.

“State-Dependence of Atmospheric Response to Extratropical North Pacific SST Anomalies”
Abstract:
By performing two sets of high-resolution atmospheric general circulation model (AGCM) experiments, we find that the atmospheric response to a sea surface temperature (SST) anomaly in the extratropical North Pacific is sensitive to decadal variations of the background SST on which the SST anomaly is superimposed. The response in the first set of experiments, in which the SST anomaly is superimposed on the observed daily SST of 1981-1990, strongly differs from the response in the second experiment, in which the same SST anomaly is superimposed on the observed daily SST of 1991-2000. The atmospheric response is characterized by an equivalent barotropic, circumglobal Rossby wave train which exhibits a significant decadal trend and can even reverse sign. The primary wave source switches from baroclinic eddy vorticity forcing over the eastern North Pacific in 1981-1990 to mean flow divergence over the western North Pacific in 1991-2000. The wave source changes are linked to the decadal reduction of daily SST variability over the eastern North Pacific and strengthening of the Oyashio Extension front over the western North Pacific. Thus, the daily and frontal aspects of the background SST variability in determining the atmospheric response to extratropical North Pacific SST anomalies are emphasized by our AGCM experiments.

“The Effect of Fault Structure on Oceanic Transform Fault Seismicity”
There is a global seismic moment deficit on mid-ocean ridge transform faults, and the largest earthquakes on these faults do not rupture the full fault area. The influence of physical fault structure, including step-overs in the fault trace, on the seismic behavior of the Discovery transform fault, East Pacific Rise, is investigated. One year of microseismicity recorded during a 2008 ocean bottom seismograph deployment and 24 years of Mw >= 5.4 earthquakes obtained from the Global Centroid Moment Tensor catalog, are correlated with surface fault structure delineated from high-resolution multibeam bathymetry. Each of the 15 5.4 <= Mw <= 6.0 earthquakes that occurred on Discovery between 1 January 1990 and 1 April 2014 was relocated into one of five distinct rupture patches. In general, microseismicity is reduced within the patches defined by the large, repeating earthquakes. While the extent of the large rupture patches on DW correlates with physical features in the bathymetry, step-overs in the primary fault trace are not observed at patch boundaries, suggesting along-strike heterogeneity in fault zone properties controls the size and location of the large events. This talk will also investigate the effect of intra-transform spreading centers (ITSC) on the underlying thermal structure of the fault, and subsequently, the size of the largest expected earthquake.

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. |
