196: The sound of seismic

Paolo Dell'Aversana highlights his article in The Leading Edge, discussing a dual-sensory approach to understanding seismic. In a first for this podcast, host Andrew Geary and Paolo discuss music's role in interpreting seismic. Based on concepts well-established in cognitive sciences, Paolo introduces the idea of expanded imaging in geophysics, using a dual-sensory (audiovisual) perception of a data set. In this episode, Paolo explains the basic principles of multimodal seismic data analysis using augmented imaging theory. He then provides examples and applications on real data at varying spatial scales, from individual seismic traces to entire seismic sections. Paolo shares the advantages and limitations of converting seismic data into an auditory format and outlines how geophysicists can start with this approach today. This episode unlocks secret information hiding in your seismic data waiting to be discovered. Listen to the full archive at https://seg.org/podcast. CELEBRATING 200 EPISODES!
