Title: Automate Glacier Terminus Picking from Big Data based on Deep Learning
Abstract: Ice sheet marine margins via outlet glaciers are susceptible to climate change and are expected to respond through retreat, steepening, and acceleration, although with significant spatial heterogeneity. However, research on ice-ocean interactions has continued to rely on decentralized, manual mapping of features at the ice-ocean interface, impeding progress in understanding the response of glaciers and ice sheets to climate change. The proliferation of remote sensing images lays the foundation for a better understanding of ice-ocean interactions and also necessitates the automation of terminus delineation. In this talk, I will focus on using deep learning (DL) techniques to automate the terminus delineation, proving the feasibility of using multi-sensor remote sensing imagery, and designing a fully automated pipeline that can continuously produce terminus traces. Finally, our pipeline has successfully picked 171,000 termini for 295 glaciers in Greenland from Landsat-5, -7, -8, Sentinel-1, and -2 images, spanning from 1984 to 2021 with an average uncertainty of ~37 meters. The high sampling frequency and the controlled quality of our terminus data will enable better quantification of ice sheet change and model-based parameterizations of ice-ocean interactions.

MG&G Field Course Presentation DayMay, 30 2025Time: 10:00 AM - 12:00 PMLocation: ROC 1.603 Each Maymester, the University of Texas Institute for Geophysics (UTIG) offers a field course designed to provide hands-on instruction for graduate and upper-level undergraduate students in the collection and processing of marine geological and geophysical data. The course covers high-resolution air gun and streamer seismic reflection, CHIRP seismic reflection, multibeam bathymetry, sidescan sonar, sediment coring, grab sampling and the sedimentology of resulting seabed samples (e.g., core description, grain size analysis, x-radiography, etc.). Scientific and technical experts in each of the techniques first provide students with several days of classroom instruction. The class then travels to the Gulf Coast for a week of at-sea field work and on-shore lab work. Two small research vessels are used concurrently: one for multibeam bathymetry, sidescan sonar, and sediment sampling, and the other for high-resolution seismic reflection and CHIRP sub-bottom profiling. Students rotate daily between the two vessels and lab work. Upon returning to Austin, students work in teams to integrate data and techniques into a final project that examines the geologic history and/or sedimentary processes as typified by a small area of the Gulf Coast continental shelf. Students spend one week learning interpretation methods using industry-standard, state-of-the-art software (Focus, Landmark, Caris, Fledermaus). On the last day, students present their final project to the class and industry sponsor representatives. |
