Mapping the hidden mosaic of Antarctica; From microplate movement to continental assembly
Due to the blanketing ice sheet and remote location Antarctic is one of the least explored and poorly understood regions on our planet. The key geological division of Antarctica is between an ancient East Antarctica craton, once at the heart of the Gondwanan supercontinent, and the collage of fragments making up the tectonically more active West Antarctic province. Within West Antarctica geological studies suggest that as a pre-cursor to the breakup of Gondwana one of these fragments, the Haag Ellsworth Whitmore Mountains block, was translated 1500 km and rotated through 90° from a position between East Antarctica and South Africa. Geophysical data has been used to challenge this notion, and suggest little or no block motion. Here we use new regional compilations and analysis of magnetic and gravity data to discuss the feasibility and implications of an alternative tectonic model with significant (500 km) movement, but limited (30°) block rotation. In contrast to West Antarctica the East Antarctic craton has been seen as a monolithic block, split by simple linear geological boundaries extrapolated from sparse coastal outcrops. However, the most up to date geophysical data from the PolarGAP survey around the South Pole supports an alternative view that East Antarctica is also a composite structure, with a complex of sutures and boundaries resulting from continental assembly, which continue to influence the sub-ice topography to this day.

DeFord Lecture | Dr. Jerry MitrovicaMarch, 28 2024Time: 4:00 PM - 5:00 PMLocation: Boyd Auditorium (JGB 2.324) New Directions in Modeling of Ice Age Sea Level and Dynamics by Dr. Jerry Mitrovica, Department of Earth and Planetary Sciences, Harvard University Abstract: Over the last decade there have been major advances in the theory and modeling of ice age sea level changes, including the development of methods that permit high spatial resolution (< 1 km) within global models, improvements in coupling to ice sheet models, and the formulation of adjoint equations that allow for efficient assessments of model sensitivities. I will highlight each advance using case studies focused on problems in paleoclimate, modern climate, and archaeology. |
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. |

UTIG Seminar Series: Crispin Little, University of LeedsApril, 12 2024Time: 2:00 PM - 3:00 PMLocation: PRC 196/ROC 1.603 Join us for a special seminar with Professor Cris Little. 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. |
