Episode 137: How near-surface geophysics protects the world

Klaus Holliger discusses his 2022 Honorary Lecture, "Using Near-Surface Geophysics to Estimate Soil and Rock Physical Properties." Klaus and host Andrew Geary explore near-surface geophysics using Klaus's Honorary Lecture as a starting point. They discuss the advantages of geostatistical techniques and two approaches to relating easy-to-measure geophysical data to more elusive rock and soil physical properties. This episode showcases the value of near-surface geophysics to the public and highlights cutting-edge techniques to better understand what's happening under our feet.

Episode 127: Breakthroughs for surface-wave tomography for the near-surface

Myrto Papadopoulou and Farbod Khosro Anjom spotlight the recent advances in surface-wave tomography for near-surface applications from August's The Leading Edge. In this episode, Myrto and Farbod discuss why surface-wave tomography has not been applied regularly to near-surface applications, highlight more efficient models they developed, explain how automatic data screening allowed for their breakthroughs, and imagine what future advances in surface-wave tomography will occur.

Episode 123: Land Seismic Case Studies with Oz Yilmaz

Oz Yilmaz discusses his latest book, Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging. Written for practicing geophysicists, this book is the culmination of land seismic data acquisition and processing projects conducted by Oz over the last two decades. His expertise and experience are highlighted in detail in this revealing and essential conversation.

Episode 106: How geophysics can help provide freshwater to the world

In this episode, host Andrew Geary speaks with Kerry Key and Chloe Gustafson on their massive freshwater discovery off the East Coast of the United States. Kerry and Chloe discuss how they used existing geophysical techniques in a new way to discover freshwater off the United States' Atlantic Coast, the equivalent amount that would fill 1.1 billion Olympic-sized swimming pools.

Episode 80: The public and scientific value of near-surface geophysics

In this episode, host Andrew Geary speaks with Sarah Morton Rupert, lead author on "Time-lapse monitoring of stress-field variations within the Lower Permian shales in Kansas" in May's The Leading Edge. This conversation is a great primer on the value of near-surface geophysics to scientists and the public. Whether building a house, building a bridge, or remediating an old salt mine, Sarah provides a lot of actionable information in this episode. And if you are wondering the best way to get engaged in the Society, Sarah has you covered there as well.

Episode 46: How science can protect infrastructure and homes

In this episode, host Andrew Geary speaks with Priyank Jaiswal, Associate Professor at Oklahoma State University. Dr. Jaiswal discusses the recent SEG near-surface event, Forum on Infrastructure, and how geophysics can play a role in this critical area. Andrew and Dr. Jaiswal discuss the potential threats to infrastructure from low-level earthquakes, how citizens and public officials can monitor and address the impact, and how geophysicists can contribute to the safety of infrastructure.

Episode 44: Using geophysics to assess and monitor infrastructure

In this episode, host Andrew Geary speaks with Steve Sloan, special section coordinator for October's The Leading Edge. October's special section focuses on using geophysics to assess infrastructure: the roads, bridges, dams, railroads, tunnels, etc. that make life easier around the world.
