Title: Cold Jets in the Solar System with Focus on Mars and Enceladus
Abstract: MARS: Spring on Mars is a time of active changes in its polar areas, at latitudes covered by seasonal CO2 ice. The volatile nature of the CO2 sublimation in spring leads to cold jet eruptions that erode the surface, redistribute loose material, and lift dust into the atmosphere. I will summarize 6 Martian Years of observations of this seasonal activity in the southern and northern Martian polar areas.
ENCELADUS: Southern polar regions of a small satellite of Saturn Enceladus are source of cold jets too, while of a very different scale. The jets of Enceladus were observed by Cassini spacecraft for more than 12 years. I will focus on their water vapor component, its modeling that was done to analyze UV observations, and the questions Cassini left unanswered.

Title: Why is projecting the sea level contribution from ice sheets so tricky?
Abstract: The Greenland and Antarctic ice sheets are the largest reservoir of freshwater on Earth, and the dominant source of uncertainty when projecting sea level. Remote sensed observations have revealed that the contemporary ice sheets are losing mass, and that their current contribution to sea level is accelerating. Whether the rate of sea level rise from the ice sheets will continue at the same pace, or what future sea level should our society prepare for, are questions that are very tricky to answer. In this presentation, I review the challenges faced by ice sheet models, along with developments that are required to make meaningful projections of Greenland and Antarctica on the timescale of the next IPCC assessment report. Finally, I will introduce the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6), which has the key objective of improving projections of sea level from the Greenland and Antarctic ice sheets, along with increasing our understanding of the cryosphere in a changing climate. These goals map into both “Melting Ice and Global Consequence” and “Regional Sea-level Change” Grand Challenges relevant to the World Climate Research Program.

Title: An adaptive Bayesian inversion for upper mantle structure using surface waves and scattered body waves
Abstract: I will present a methodology for 1-D imaging of upper mantle structure using a Bayesian approach that incorporates a novel combination of seismic data types and an adaptive parameterisation based on piecewise discontinuous splines. This inversion algorithm lays the groundwork for improved seismic velocity models of the lithosphere and asthenosphere by harnessing the recent expansion of large seismic arrays and computational power alongside sophisticated data analysis. Careful processing of P- and S-wave arrivals isolates converted phases generated at velocity gradients between the mid-crust and 300 km depth. This data is allied with ambient noise and earthquake Rayleigh wave phase velocities to obtain detailed VS and VP velocity models. Synthetic tests demonstrate that converted phases are necessary to accurately constrain velocity gradients, and S-p phases are particularly important for resolving mantle structure, while surface waves are necessary for capturing absolute velocities. We apply the method to several stations in the northwest and north-central United States, finding that the imaged structure improves upon existing models by sharpening the vertical resolution of absolute velocity profiles, offering robust uncertainty estimates, and revealing mid-lithospheric velocity gradients indicative of thermochemical cratonic layering. This flexible method holds promise for increasingly detailed understanding of the upper mantle.

Title: Ice and mud: how sediment dynamics drive periodicity in tidewater glaciers
Abstract: Many tidewater glaciers in Alaska, such as Hubbard, Taku, and Yahtse, are growing despite a warming atmosphere and ocean. At the same time, close neighbors such as Columbia glacier are undergoing dramatic retreats, which cannot be accounted for by climate change. What drives this apparent disparity in glacier behavior? A hypothesized process known as the tidewater glacier cycle provides an explanation: movement of sediment by subglacial streams produces a shoal at the glacier front, decreasing the amount of iceberg calving and allowing the glacier to advance over several hundred years. Eventually the glacier becomes overextended, floats, and quickly retreats to its initial shape. In this talk, I will show (with the help of computer model) that simple interactions of ice, water, and erosion can produce tidewater glacier cycles like the ones that are observed in coastal Alaska, and that these cycles occur even in a static climate and persist with warming. I argue that these cycles drive natural shifts in marine habitat and the fjord landscape at large and must be accounted for in interpretations of glaciers as climate proxies.

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. |
