요약Distributed Acoustic Sensing (DAS) transforms optical fibers into dense arrays capable of detecting small strain changes caused by vibrations in the surrounding medium. With each fiber segment functioning as a virtual sensor, DAS generates rich spatiotemporal data, with meter-scale spatial resolution, kilometer-scale sensing distance, and kilohertz-range temporal sampling. This capability opens new possibilities for detecting signals ranging from earthquakes to whale calls and footsteps, and continues to expand into new application domains.Effectively applying DAS requires careful attention to the contextual factors that shape signal clarity, reliability, and interpretability: how the fiber is deployed, the surrounding environment, and the characteristics of the DAS system. Mechanical coupling to the surrounding material, subtle variations in fiber tension or geometry, ambient noise conditions, and the configuration of data acquisition parameters can all influence signal amplitude, polarization, and noise characteristics. As a result, the same physical event may manifest differently in DAS recordings across deployments, making DAS data variable and context-sensitive.This dissertation focuses on understanding signal variability, ensuring data quality, and applying rigorous modeling to develop workflows that remain robust, adaptive, and reproducible. Three case studies illustrate this approach: detecting humpback whale vocalizations in Monterey Bay, monitoring roadway activity across different fiber deployments, and characterizing signals from hydraulic fracturing. Each highlights domain-specific challenges in event detection, characterization, and classification under real-world constraints such as environmental noise, infrastructure heterogeneity, and labeling uncertainty. This document provides grounded, experience-based guidance to help researchers more effectively leverage DAS's unique capabilities while working with its numerous complexities.
