AGU 2025 – Call for Abstracts: Fiber-Optic Sensing in Natural Systems
Jiaxuan Li
Dear colleagues,
We invite you to submit an abstract to AGU 2025 Session S012: Geophysical Advances with Distributed Fiber-Optic Sensing in Natural Systems.
Fiber-optic sensing, particularly Distributed Acoustic Sensing (DAS), is revolutionizing geophysical observation by enabling dense, long-range, and cost-effective measurements across diverse environments and timescales. This session will showcase how DAS and related technologies are transforming seismic monitoring, environmental sensing, and subsurface imaging in natural systems and beyond.
We welcome contributions related to:
- Earthquake detection and early warning
- Seismic source characterization
- Subsurface imaging and monitoring
- Applications in volcanic, glacial, permafrost, and planetary settings
- Environmental sensing in oceans, rivers, and lakes
- Sensing of dynamic and quasi-static phenomena such as tides, tsunamis, debris flows, landslides, and magma intrusions
We are also interested in:
- Real-time and scalable workflows, including signal processing, compression, and automation
- Innovative uses of existing infrastructure, including urban and subsea telecom cables
- Exploratory work on alternative fiber-optic sensing technologies, such as polarization sensing and long-range transmission systems.
Submit your abstract: https://agu.confex.com/agu/agu25/prelim.cgi/Session/250861
Deadline: Wednesday, July 30, 2025
We aim to highlight unique observations, innovative methodological developments, and integrative approaches that are redefining the possibilities of fiber-optic sensing. Join us in shaping this fast-growing field. We look forward to your contributions!
