Geophysical Advances with Distributed Fiber-Optic Sensing in Natural Systems
Session ID#: 250861
Session Description:
Fiber-optic sensing technologies, particularly Distributed Acoustic Sensing (DAS), are transforming geophysics by enabling dense, long-range, long-duration, and cost-effective sensing across diverse environments. We invite submissions on earthquake detection and early warning, source characterization, subsurface imaging, environmental monitoring, and other geophysical monitoring applications in settings such as urban areas, volcanic systems, glaciers, permafrost, oceans, rivers, and lakes, and potential planetary environments. Topics may range from high-frequency signals from marine mammals and vessel activity to lower-frequency phenomena such as internal waves, tides, tsunamis, and quasi-static deformations caused by landslides, debris flows, and magma intrusions. We also encourage contributions on the scalability of fiber-optic sensing in geophysics, including real-time processing, compression, and end-to-end workflows that support effective use of the large-volume data. While DAS is the central focus of this session, we welcome exploratory work on alternative fiber-optic sensing technologies, such as long-range systems for subsea cables, polarization sensing, or transmission-based systems.
