"Physics-based approaches are like solving a puzzle with a set of rules. Data-driven geophysics is more like giving the puzzle to a computer that can learn the rules itself." Amine Ourabah shares how data-driven geophysics is transforming our understanding of the subsurface by combining physics with the power of machine learning. He explains how new tools, such as nimble nodes and distributed acoustic sensing, are making seismic imaging faster, cheaper, and more accessible across various industries, including oil and gas, geothermal, and carbon storage. Amine also highlights the importance of curiosity, adaptability, and simplicity in shaping the next generation of geophysicists and technologies.

“Distributed chemical sensing really is the next frontier in fiber-optic monitoring. It adds a new dimension by directly connecting chemical changes in the environment to signals we can read.” Distributed chemical sensing (DCS) is an emerging technology that utilizes fiber optics to measure chemical changes over long distances in real-time. Authors Christian Totland, Thomas Dylan Mikesell, and Peter James Thomas join host Andrew Geary to discuss their new paper, "Distributed chemical sensing: An unexplored frontier in urban, industrial, and environmental monitoring." Unlike traditional point sensors, which only capture data at one location, DCS has the potential to provide continuous chemical information with both high spatial and temporal resolution. This innovation could transform how we monitor pipelines, groundwater, and industrial sites, while also opening new opportunities for collaboration between geophysics, chemistry, and material science. KEY TAKEAWAYS > DCS can detect leaks, contamination, and ch

"By mapping fiber optic cables accurately, we can transform them into dense seismic arrays. This opens the door to city-scale imaging and monitoring." Haipeng Li explains how distributed acoustic sensing (DAS) can turn existing urban fiber optic cables into powerful seismic arrays for near-surface imaging and monitoring. By using everyday traffic and ambient noise, his team can track groundwater changes, detect geohazards, and study fault structures without costly field deployments. This approach offers a new way for geophysicists, engineers, and city planners to work together for safer, more resilient urban environments. KEY TAKEAWAYS > Existing fiber optic cables can be transformed into dense, city-scale seismic arrays using DAS technology. > Vehicle-induced seismic waves provide highly repeatable data for monitoring small subsurface changes, while ambient noise helps extend imaging depth. > Urban DAS monitoring can reveal how infrastructure affects groundwater recharge and can support hazard assessment a
