Distributed Acoustic Sensing Under a Lake

Project Goals and Description:
In summer 2021 we deployed an optical fiber cable at the bottom of Lake Hattie in Wyoming. We connected the cable to a Distributed Acoustic Sensing (DAS) interrogator and recorded about 16 hours of data overnight. The main goal of the project is to estimate seismic velocity structure at the lake bottom using seismic interferometry method. Another goal is to characterize vibration signals at the lake bottom induced by fish activity and water waves.
