Multi-Modal Fiber Sensing for OffshoreEnvironmental and Infrastructure Monitoring

Abstract

Monitoring a 118 km subsea cable using Distributed acoustic, state-of-polarization, and Brillouin sensing captured storm-induced strain up to $\approx 0.003\hat{I}¼\hat{I}\mu$ (dynamic) and $\approx 180\hat{I}¼\hat{I}\mu$ (static), demonstrating consistent yet distinct modal responses to environmental loading.
