Yanlong Niu discusses his paper, "In-situ physical properties of reclaimed lands in Singapore," from the May issue of The Leading Edge. Reclaimed land construction is crucial for the sustainable development of the land-scarce city-state of Singapore. To characterize the physical properties of two different types of reclaimed lands, Yanlong and his co-authors conducted both active and passive seismic surveys. Yanlong explores the value of multichannel analysis of surface waves to investigate these lands and shares what they discovered with these pioneering tests. These in-situ measurements are crucial for civil engineering constructions and the redevelopment of reclaimed lands in the future. So he also offers tips on how other geophysicists can build upon this study in their communities.

Ariel Lellouch discusses his upcoming Middle East and Africa Honorary Lecture, "Applications of fiber-optic sensing to borehole seismology." Distributed Acoustic Sensing (DAS) is an emerging technology that leverages optical fibers to record the seismic wavefield with an unprecedented spatial resolution. In this conversation with host Andrew Geary, Ariel makes a case for geophysicists to utilize DAS data in their work and why it's essential to look at data without any pre-made ideas. He also outlines the significant benefits of vertical DAS arrays and how to know when to use vertical or horizontal DAS. This is an excellent primer on DAS and a convincing case for why every geophysicist would benefit from engaging with this technology.

Mojtaba Rajabi discusses his upcoming Pacific South Honorary Lecture, "Present-Day Crustal Stress Across Spatial Scales." The present-day crustal in-situ stress field is of extreme importance for understanding both natural processes (e.g., understanding neotectonics, earthquake, and seismic hazard assessment) and anthropogenic activities (e.g., exploration and production of geothermal energy, groundwater, hydrocarbon, mineral resources, CO2, and hydrogen geo-storage). Analysis of the present-day stresses in numerous basins from across the world reveals that significant and complex variations in the present-day stress orientation are commonly observed at different scales. Mojtaba's lecture aims to investigate the pattern of crustal stress at different spatial scales to better evaluate the causes and consequences of contemporary stress in the earth’s crust. In this conversation with host Andrew Geary, Mojtaba shares why it's necessary to understand the present-day crustal in-situ stress field, the impact of i

Peter Rowbotham discusses his paper, "Investment in North Sea seismic leading to new opportunities," from the April issue of The Leading Edge. Peter makes the case for why it's wise to invest in seismic data. He also shares why the beginning of a project is the most important and the context where seismic projects deliver the most value. Additionally, he answers the questions: * How does he approach deciding whether to acquire a new 3D seismic survey or seek to reprocess legacy 3D surveys for a particular area? * Why does he believe the beginning of a project is the most important? * During the processing phase, why does he advocate for obtaining interim volumes at every opportunity?

Yunyue Elita Li discusses her upcoming South & East Asia Honorary Lecture, "Listening to Singapore: Harvesting urban noise for space, water, and hazard mitigation." Today, more than half of the world's population lives in urban areas with a projected growth of over two-thirds in 2050. The city-state of Singapore faces the challenges of supporting a sustainable urban system with a growing population in a limited land, sea, and air space. The only direction to develop is toward the subsurface. In this conversation with host Andrew Geary, Elita shares how she designed novel signal processing techniques that turn urban hum into rich information about the urban system, both above and below the surface. She also highlights newly-developed fiber sensing technology using existing dark fiber infrastructure that has the potential to enable a million-sensor system underneath each major city around the globe. Elita also outlines what public officials, citizens, and engineers should understand about geophysics to suppo

Pico de Orizaba is the highest volcano in Mexico and preserves a glacier at the top. The volcano is an old structure and has experienced several cone collapses and subsequent rebuilds in its eruptive history of fewer than 600,000 years. Thinking about the potential threat to villages located along the major river drainages, Drs. Katrin Sieron and Blake Weissling submitted a Geoscientists without Borders (GWB) proposal (https://seg.org/About-SEG/Geoscientists-Without-Borders/Projects/detail/veracruz-and-puebla-states-mexico-2) to monitor precipitation at altitudes over 4000 meters above sea level and to better characterize the lahar forming zone at the proglacial ramp. They also wanted to work on lahar (mud or debris flows) detection and monitoring and create a lahar-warning system for local habitants. More than 15 students were involved during the project execution, several of whom worked on virtually supported thesis proposals (geomorphology, hydrology, glacier modeling, lahar modeling, vulnerability studi

Laura Bandura discusses her 2022 Distinguished Lecture, "Quantifying the Business Impact of Seismic Technology to Deepwater Exploration." In a low oil price environment, it is more important than ever to prioritize technology projects to ensure the greatest return on investment. There is much pressure to accelerate the time-to-impact of corporate research and technology programs. In many cases, the geoscientists who are developing these breakthrough technologies are expected to demonstrate the value of these initiatives, which requires both a high degree of subject matter expertise and business fluency. In this practical conversation, Laura and host Andrew Geary showcase how to communicate technological value and your expertise to decision-makers. Laura shares how to tie your work to financial metrics, the power of simplicity and brevity, and how geoscientists can better understand decision-makers.

Klaus Holliger discusses his 2022 Honorary Lecture, "Using Near-Surface Geophysics to Estimate Soil and Rock Physical Properties." The shallow subsurface contains our drinking water and produces our food, and it is also where we ultimately discharge much of our waste. Recent history has taught us that overuse, let alone abuse, of our environment, may lead to the long-term detriment to our livelihood. The protection and sustainable use of this fragile surficial environment has therefore become a societal and political issue of critical importance. Near-surface geophysics has an essential role to play in this endeavor. 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

Joe Dellinger discusses his 2022 Distinguished Instructor Short Course, "Forensic data processing." Are you a geophysicist that processes seismic data, or someone who uses the processed results of that data? If so, you probably think of seismic data as something that arrives on a tape or "from the cloud." However, your data also has other, hidden stories to tell - stories that likely were shredded and lost when you chopped the data into traces and fed it into your algorithms for processing. We typically call anything our algorithms are not designed to deal with "noise." Can we make use of such "noise," or at least better understand it? If we understood it, could we do something useful with it (or at least have a better idea of how to suppress it)? The goal of Joe's course - and this conversation - is to get you thinking more critically about your data. How was it recorded? What is in it? What happened to it on the way from the field to numbers in a file? Joe brings his experience, expertise, wisdom, and h
