    From Classroom to Community: A GWB Project Tackles Groundwater Contamination

    “This project really bridged the gap that we get from just learning in university and actually doing it in real life. It is actually making an impact on society.” Stella Eulia Andoka and Michael Partogi share how their student team used applied geophysical tools to investigate groundwater contamination affecting more than 2,600 families living near the Cipayung landfill in Indonesia. With support from the SEG Foundation and Geoscientists Without Borders, the project expanded beyond data collection to include community education and engagement with residents, schools, and local decision-makers. Their work shows how resourceful, student-led teams can deliver meaningful, real-world impact through applied geoscience. KEY TAKEAWAYS > Student-led geophysics projects can have a direct impact on community awareness and local decision-making. > Modest funding can deliver strong returns when teams work creatively and efficiently. > Applied geophysics becomes more powerful when paired with education and community trust.

    What It Takes to Trust AI in Real-World Seismic Applications

    “Deep learning is ubiquitous in data processing. The question is whether we have the courage to change the way we work.” Yangkang Chen discusses how deep learning has moved from experimentation to production in seismic processing and earthquake monitoring. Drawing on a decade-long effort to build an operational AI-driven monitoring system, he explains why tasks like first-arrival picking, velocity analysis, denoising, and reconstruction are especially well suited for deep learning. Yangkang emphasizes that success depends not just on algorithms, but on benchmarks, stability, teamwork, and trust. He also highlights how open and reproducible research lowers barriers for adoption and helps geophysicists apply AI confidently in real workflows. KEY TAKEAWAYS > Deep learning excels at repetitive, label-intensive seismic tasks that are slow and inconsistent using traditional methods. > Operational AI requires trust, built through benchmarks, validation, and a clear understanding of model behavior. > Open and reproducible workflows accelerate adoption, collaboration, and innovation across the geophysics community. Register for his course, Deep learning for revolutionizing seismic data processing, on March 24-25, 2026 at https://seg.org/shop/product/?id+=product&id=5c3b6821-549d-f011-b41b-7c1e521913ef.

    Two Trillion-Dollar Ideas Leon Thomsen Tried to Give Away

    “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.
