“It’s not only about discovering resources, but about safeguarding them and safeguarding our future. When you understand the subsurface, you understand the foundation of food security, water security, and environmental stability.” Ahmed Elshenawy, SEG’s 2026 Middle East and Africa Honorary Lecturer, explores how geophysics can help solve some of today’s biggest challenges in agriculture and environmental management. In this conversation, he explains how imaging the shallow subsurface can reveal hidden patterns of soil moisture, salinity, and groundwater movement that shape farming success. His work shows how understanding what lies beneath our feet may be key to sustainable agriculture, climate resilience, and the future of food and water security. Learn more about Ahmed's lecture and register for his 12 March webinar - https://seg.org/education/lectures/seg-honorary-lecture-ahmed-elshenawy/ KEY TAKEAWAYS > Geophysical tools can map soil moisture, salinity, and subsurface conditions that directly affect agriculture and water management. > The same methods used in energy and mineral exploration can support sustainability, land restoration, and climate adaptation. > Students who combine geophysics with hydrology, soil science, and data science will find growing career opportunities in environmental and agricultural applications. GUEST BIO Since 2000, Ahmed has been involved as a research team member of several national, international, and private projects regarding the application of geophysical methods for groundwater exploration, water management, aquifer characterization, desertification process monitoring, sustainable development, engineering, geotechnical and environmental problems.

“The major pitfall of machine learning of any kind is to be overly confident in the results. We run the risk of garbage in gospel out.” This discussion offers a rare chance to go a little deeper into a Leading Edge article and hear directly from the authors about the thinking behind their workflow. Satinder Chopra and Kurt Marfurt walk through how unsupervised machine learning, careful attribute selection, and simple preprocessing steps can reveal subtle channel features in a deepwater New Zealand example. It feels less like a theory lesson and more like practical guidance on using machine learning as a helpful partner in everyday seismic interpretation. KEY TAKEAWAYS > Small workflow choices have big impact. Clean input data, thoughtful attribute selection, and simple normalization steps often determine whether machine learning highlights geology or just amplifies noise. > The value is in the combination of tools and judgment. Unsupervised methods quickly expose patterns, but interpreters still need to compare results with seismic sections, wells, and regional context to confirm what is real. > PCA and SOM make complex attribute sets easier to explore. By reducing dozens of attributes into clearer clusters, they help interpreters see channel shapes and reservoir variability that might otherwise be overlooked.

“Oil company management has to understand that its business is essentially a technology business. It's not a marketing business.” In this episode of Seismic Soundoff, Andrew Geary speaks with Dr. Leon Thomsen about his memoir, “‘Surely You’re Joking, Mr. Thomsen!’: Adventures of a Petroleum Scientist,” and a career that helped redefine applied geophysics. Leon reflects on the experiences that shaped his scientific mindset, from early exposure to field crews, to formative lessons in geology at Caltech, to decades of research in academia and industry. He explains how curiosity-driven exploration led him to recognize the importance of seismic anisotropy and shear-wave technology, work that ultimately carried trillion-dollar implications for hydrocarbon exploration. The conversation also explores why transformative ideas often struggle inside large organizations, how a lack of technological literacy in management can lead to missed opportunities, and why applied science can be every bit as creative and demanding as pure research. Looking ahead, Leon shares his perspective on the future of applied geophysics, including opportunities in fracking optimization, carbon sequestration monitoring, and subsurface hydrogen exploration, and offers encouragement to young scientists preparing to navigate the energy transition. KEY TAKEAWAYS > Energy is a technology business: Long-term success depends on leadership that understands and trusts science, not just short-term metrics. > Applied science is real science: Solving practical problems can be as intellectually challenging and rewarding as purely theoretical work. > The next frontier is subsurface innovation: Geophysics will play a critical role in fracking efficiency, CO₂ monitoring, and hydrogen exploration during the energy transition.

“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.

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. LINKS * Haipeng Li, Jingxiao Liu, and Biondo L.

"The glossary will bridge two complex worlds, geoscience and sustainability, and make them easier to understand." Maria Angela Capello shares her vision for a new glossary that connects geoscience to sustainability in clear, practical terms. She explains how a shared vocabulary can help scientists, educators, and policymakers better understand the purpose and global impact of geoscience work. By linking technical expertise to the UN Sustainable Development Goals, the glossary aims to inspire collaboration, education, and a stronger sense of purpose across the profession. KEY TAKEAWAYS > A dedicated glossary can make sustainability concepts easier to understand and apply in geoscience work. > Geoscientists contribute to all 17 UN Sustainable Development Goals, not just climate-related ones. > Clear, shared language can help connect technical work to education, policy, and public understanding. GUEST BIO Maria Angela Capello (MAC) is a global leader in the energy sector, championing sustainability, equity, and diversity. An active collaborator with the United Nations and major geoscience societies, she has been honored with Italy’s Star of Italy knighthood and UNESCO recognition for advancing the UN Sustainable Development Goals. A sought-after speaker and author of three books, MAC is the only person to serve as a Distinguished Lecturer for AAPG, SPE, and SEG. She advises on sustainability, ESG, and leadership worldwide, with certifications from Cambridge University and IFP School.
