“From Initiation to Termination – The Critical Role of Magma in Rift Evolution”
Abstract:
The evolution of the continental lithosphere during the rupture of continents involves a series of processes that requires a multi-disciplinary approach to their study. Geochemistry provides a powerful tool that can augment geophysical and tectonic observations and provide a unique control on the rifting process. In this talk we will examine the geochemical evidence for mantle plume contributions to rift magmatism, the consequences of lithospheric thinning on magma generation, and the long term impact of rifting processes on the upper mantle. Our focus will be on the East African Rift – the archetypical example of continental rifting, with application to magma-rich rifting worldwide.

“The Southern Ocean Reveals Its Climate Secrets: Paleotemperatures from Antarctic Margin Marine Sediments”
Abstract:
The disintegration of ice shelves, reduced sea-ice and glacier extent, and shifting ecological zones observed around Antarctica highlight the impact of recent atmospheric and oceanic warming on the cryosphere. Observations and models suggest that oceanic and atmospheric temperature variations at Antarctica’s margins affect global cryosphere stability, ocean circulation, sea levels and carbon cycling. In particular, recent climate changes on the Antarctic Peninsula have been dramatic, yet the Holocene climate variability of this region is largely unknown, limiting our ability to evaluate ongoing changes within the context of historical variability and underlying forcing mechanisms.
Knowledge of Antarctica’s cryosphere evolution over the last 65 million years is derived from far-field deep-sea sediment records. Yet detailed studies of Antarctic margin sediments required to evaluate observed changes in the context of historic variability are lacking. Recent advances in drilling technology and geochemical climate proxies now make it possible to retrieve, date, and interpret high-quality ice-proximal sediment sequences from Antarctica’s margins. These sequences, often devoid of calcium carbonate, contain information about the individual histories of the East and West Antarctic Ice Sheets and Southern Ocean temperatures.
We present a TEX86-based ocean temperature reconstruction from ODP Site 1098 (64°51’S, 64°12’W; 1010 meters water depth), which reveals a 3-4°C cooling near the western Antarctic Peninsula from 12 to 2 ka. Similar Holocene cooling is identified in Antarctic ice cores, Southern Ocean sediments, and model runs, highlighting the importance of local (65°S) spring insolation on Antarctic summer duration, ocean temperatures, and sea ice extent. On millennial timescales, TEX86-based ocean temperature reconstructions correspond with local/regional terrestrial temperature, westerly wind, and El Niño/Southern Oscillation variability, indicating that climate teleconnections between the tropical Pacific Ocean and the western Antarctic Peninsula strengthened late in the Holocene.
We conclude that during the Holocene, Southern Ocean temperatures at the western Antarctic Peninsula margin were tied to changes in the position of the Westerlies, which have a critical role in global carbon cycling. The Antarctic margin is Paleoceanography’s final frontier. It is where we can best test hypotheses that oceanic and/or atmospheric temperatures at Antarctica’s margins affected past cryosphere stability, global ocean circulation, sea levels and carbon cycling.

“Seismicity, Seawater and Seasonality: Tracking Ice Loss From the Fronts of Tidewater Glaciers”
Abstract:
The largest and most rapidly changing glaciers on Earth flow into the ocean. Ice loss from these glaciers will be the largest contributor to sea level rise in coming centuries and is also the least certain component of the sea level budget. These uncertainties are driven in large part by the poor understanding of two processes by which tidewater glaciers and ice sheets lose ice at their termini: submarine melting by warm ocean water and mechanical iceberg calving.
The fronts of tidewater glaciers are among the most active and inaccessible geological environments. These challenges have limited the long duration, high resolution calving and melt measurements that yield insight. Using seismology and oceanography, I identify the magnitudes and variability of submarine melt and iceberg calving at Yahtse Glacier, a major tidewater glacier in southern Alaska. I find that the submarine portion of the glacier terminus melts at over 10 m/d during much of the year. In addition, cavitation of icebergs beneath the sea surface can generate seismometer-recorded “icequakes,” revealing that calving varies seasonally and in response to ocean tides. Seismic tremor also offers the first ever view of subglacial discharge from a tidewater glacier. Discharge increases during late summer, which promotes submarine melt. Together, these multidiscipline observations improve our understanding of the geophysical processes responsible for rapid ice loss across the cryosphere.

“Coral Records of Paleo-Uplifts in Southwest Pacific Forearcs: Recurrence Times, Geography of Uplift, and Uplift Rates Varied Drastically Over a Few Thousand Years”
Abstract:
Our established concepts regarding recurrence intervals and geography of megathrust ruptures tend to assume that there must be significant orderliness and regularity in recurrence intervals and rupture surfaces. This may turn out to be true at some subduction zones. However, coral paleogeodetic records from the Western Solomons and central Vanuatu forearcs conflict with this idea. The intervals between large uplifts are quite variable. Maybe the very idea of a recurrence interval is misleading. At both the Solomons and Vanuatu forearcs, recent coseismic vertical deformation geography conformed to expectations for elastic strain release on a megathrust of geologically reasonable orientation. Vertical interseismic elastic strain should be roughly the mirror image of coseismic elastic strain release. However, we find considerable heterogeneity in the geography of paleo-uplift amounts and ages compared with 2007 coseismic uplift. Could it be that the paleo-earthquakes were so different than the modern ones? Not likely. The subsidence geography preceding the 2007 megathrust rupture in the Solomons is significantly different from the 2007 coseismic uplift distribution, indicating that uplift distribution is strongly influenced by interseismic processes (i.e. uplift results from a deficit in subsidence rather than an excess of uplift). Therefore, we expect that the 2007 uplift pattern will be modified before the next large interplate event and the same probably happened with previous coseismic uplifts. In fact, very few paleogeodetic records from any outer forearcs exist anywhere, in large measure due to the fact that most forearc areas overlying the seismogenic zone are underwater. Even if these SW Pacific locations turn out to be somewhat special cases at least we can recover the chaotic Vanuatu and Solomons paleogeodetic histories, which puts us leagues ahead of what can be done in most forearcs. And just maybe they are not really all that different from other arcs when the final score is posted.

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.

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. |
