“Understanding Variability in Ice Dynamics at the Margins of the Greenland Ice Sheet”
The margins of the Greenland Ice Sheet have undergone rapid and significant changes in recent years. This includes drawdown of the ice sheet surface, acceleration of both land and ocean-terminating ice, and retreat of outlet glaciers. Predicting the magnitude of and causes behind these changes is difficult. In part, this is because of a lack of observational data, but also because there is no consensus on the relative importance of various physical processes that control glacier changes. Much research has focused lately on the role that meltwater plays in ice sheet acceleration. Meltwater reaches the bed through moulins, which are likely formed from crevasses in locations where plentiful meltwater supply is generated. Some moulins can remain open and partially water-filled all year, which suggests that routing of meltwater to the bed remains spatially fixed for some period of time. Meltwater supplied via moulins causes ice sheet acceleration on daily, seasonal and event time scales although longitudinal flow coupling can explain many of the smaller variations in speed near and above the equilibrium line. Unlike in alpine glaciers, subglacial water pressure is out of phase with ice speed, while the water levels measured in moulins is in phase with ice speed. This suggests that the moulins are the primary pathway for getting water to the bed in Greenland and that water input through moulins drives localized fast flow. In addition to this we find that air temperature does not directly translate into increased sliding as suggested by many authors and this suggests evolution of the subglacial conduit system over time. These observations suggest that we need to model the subglacial hydrology of the Greenland ice sheet as supplied from point sources to an growing/shrinking conduit system that induces local slip events, which propagate outwards radially from the moulin.
DeFord Lecture | Dr. Richard TaylorApril, 25 2024Time: 4:00 PM - 5:00 PMLocation: Boyd Auditorium (JGB 2.324) Adapting to the Amplification of Climate Extremes Through Freshwater Capture: Evidence from the Tropics by Dr. Richard Taylor, Department of Geography, University College London Abstract: In low-income countries of the tropics undergoing rapid growth, global warming presents challenges to the expansion and sustainability of water supplies required to advance progress toward the United Nations’ Sustainable Development Goals. Substantial uncertainty persists in projections of precipitation under climate change. A widely observed impact, pronounced in the tropics, is the intensification of precipitation comprising a transition towards fewer but heavier rainfalls. How does this transition impact terrestrial water balances? How might these changes influence freshwater demand? I will interrogate these questions and review mounting empirical evidence from the tropics of the resilience to climate change of groundwater resources, which act as a natural inter-annual store of freshwater supporting adaptation to the amplification climate extremes. Presented evidence includes case studies and local-to-regional scale analyses from tropical Africa and the Bengal Basin of South Asia. Outcomes emphasize the interconnected nature of surface water and groundwater as well as the value of groundwater as a natural, distributed store of freshwater. This insight provides a platform to explore more equitable and sustainable water development pathways resilient to climate change. |
UTIG Seminar Series: Cornelia Rasmussen, UTIGApril, 26 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Cornelia Rasmussen, Research Associate, University of Texas Institute for Geophysics Host: Krista Soderlund Title: The Emerging Field Of Position-Specific Isotope Analysis: Applications in chemical forensics, exobiology, geo- and environmental sciences Abstract: Complex organics can be found all over our solar system and within each living thing on our planet, be it as part of its physiology or as a contaminant. 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. |
