CTEMPs Training on Fiber-Optic Sensing Systems
One-Day AGU Training Workshop — In Person
When: Wednesday, 17 December 2025-08:30 AM – 5:00 PM CT
Where: New Orleans Ernest N. Morial Convention Center, Rooms 333–334
Registration:
Please register through AGU Confex.
Venue access requires AGU Annual Meeting registration, and this workshop also requires a separate workshop ticket.
The organizing team can’t process registrations by email.
Capacity: Limited seating; target cap 40 seats.
Modality: In-person only (no virtual/hybrid option per AGU).
Workshop at a Glance
A fast-paced, hands-on introduction to Distributed Acoustic Sensing (DAS) and Distributed
Temperature Sensing (DTS) for Earth and environmental applications. Learn the essentials of
field deployment, acquisition, quality control, and first-look processing/interpretation through
live demos, curated datasets, and practical exercises.
Format: Full-day
Hours: 8:30 AM – 5:00 PM CT (breaks provided; lunch per AGU)
Audience: Researchers, Grad students, and practitioners in geophysics, hydrology,
civil/environmental engineering, natural hazards, and environmental sensing.
What You’ll Learn
- Fundamentals of DAS & DTS hardware/interrogators (capabilities, limitations, safety)
- Installation & coupling options (native soil, sand backfill, conduit)
- Acquisition planning (sampling, gauge length, SNR, bandwidth, time sync, metadata)
- QC & troubleshooting (noise sources, coupling diagnostics; vibroseis & ambient examples
- First-look processing workflows (filtering, spectrograms, coherence, stacking/decimation)
- Environmental & geohazards use cases
