As the size and complexity of data soars exponentially, machine learning (ML) has gained prominence in applications in geoscience and related fields. ML-powered technology increasingly rivals or surpasses human performance and fuels a large range of leading-edge research.

In this conversation with host Andrew Geary, mathematician Herman Jaramillo discusses his new book, Machine Learning for Science and Engineering Volume One: Fundamentals. This book teaches the underlying mathematics, terminology, and programmatic skills to implement, test, and apply ML to real-world problems. It builds the mathematical pillars required to comprehend and master modern ML concepts thoroughly and translates the newly gained mathematical understanding into better-applied data science.

Herman explains why this book is a unique contribution to the growing field of machine learning, the role of intuition in using ML, and what's in this book that you rarely find in other ML books. He also goes in-depth on the critical understanding of finding the best-suited algorithm. This conversation and book explore the hottest topics facing students, scientists, and engineers. And this episode will provide a solid foundation to understand how to utilize this cutting-edge science in your work.

Dr. Herman Jaramillo teaches at the University of Medellín and is a member of the Research Group on Scientific Modeling and Computing.

262: More Than Membership - Turning SEG Engagement into Career Growth

“Repeatability is the biggest hurdle in time-lapse monitoring, but it’s also where the opportunity lies. 4D FWI can help address those repeatability challenges.”

On this episode, Andrew Geary sits down with Madhav Vyas and Kris Innanen, guest editors for July’s The Leading Edge special section on 4D full-waveform inversion. They explain how 4D FWI goes beyond traditional differencing by fully inverting wavefields, making time-lapse seismic more robust against survey inconsistencies and complex overburden. Listeners will learn why now is the perfect time to adopt 4D FWI, the main technical hurdles around repeatability and uncertainty, and the first steps to take for reservoir monitoring and survey design.

KEY TAKEAWAYS
> 4D FWI inverts the full wavefield - reflections, refractions, diving waves, multiples - to detect reservoir changes, making it more robust than conventional 4D processing.
> Repeatability of surveys and assessing uncertainty are the biggest challenges, but workflows like hypothesis testing, batch FWI, and null-space shuttling help mitigate inversion noise.
> High-quality data and accurate physics (elasticity, attenuation, anisotropy) are essential; advances in GPU-driven computation enable faster iterations and richer uncertainty analysis.

The transformative role of LLMs in geophysics education

For this episode, we’re re‑releasing one of the most powerful stories we’ve ever told - a complete listening experience that transports you to one of the most remote and challenging places on Earth.

Searching for Water in Kakuma takes you inside the second‑largest refugee camp in the world, home to more than 185,000 people and still growing. There, a team of Canadian geophysicists joined forces with determined refugees and locals to take on a life‑or‑death challenge: finding safe, sustainable water for tens of thousands in East Africa.

This episode offers an unflinching look at the obstacles, breakthroughs, and human resilience at the heart of applied geophysics.

If you’re new to Seismic Soundoff, we’re glad you’ve chosen to listen. This podcast shares stories that connect geoscience to real‑world impact - from breakthrough research and innovative technology to the people applying them to solve Earth’s toughest challenges.

Starting September 11, we’ll release three brand‑new interviews every week, bringing you fresh voices and powerful stories from across the geoscience community.

For now, please enjoy this deeply personal and meaningful story.

The Missing Tool Every Geoscientist Needs for the Next Decade

"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 and infrastructure planning.

GUEST BIO
Haipeng Li is a third-year Ph.D. candidate in the Geophysics Department at Stanford University, advised by Biondo Biondi in the Stanford Earth Imaging Project (SEP). His research centers on spatiotemporal subsurface monitoring, with a focus on developing efficient and robust time-lapse seismic waveform inversion methods and uncertainty quantification approaches. He applies these techniques to real-world challenges such as geological CO2 sequestration for the energy transition and groundwater monitoring in urban environments, often leveraging Distributed Acoustic Sensing (DAS) data. He is a student member of the AGU, SSA, and SEG.

The Low-Cost Seismic Revolution Already Buried in Your City

“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 chemical changes directly, offering more accurate monitoring than pressure or temperature proxies.
> The technology is still in its early stages, which means there are many opportunities for research, innovation, and interdisciplinary collaboration.
> If developed further, DCS could provide affordable, real-time monitoring for critical infrastructure and environmental systems worldwide.
