ESC-SSA Joint Session:Seismology in the Global Oceans: Advances in Methods and Observations
Seismological studies beneath the global oceans, which cover 70% of Earth's surface, provide key insights into tectonic processes. These investigations have advanced our understanding of fundamental topics such as the differences between oceanic and continental lithosphere-asthenosphere systems, the evolution of oceanic plates from mid-ocean ridges to subduction zones, and the influence of mantle plumes in these processes. Seismic imaging of subduction zones and transform faults has also been instrumental in improving our understanding of earthquake hazards and volcanic activity.
This session invites contributions that showcase recent advancements in overcoming the challenges of collecting, processing, and interpreting oceanic seismic data. Topics may include but are not limited to, innovations in noise reduction (e.g., reverberations, tilt, compliance, bottom currents), the use of probabilistic and machine learning methods for modeling wave reflections and conversions, and novel approaches to imaging oceanic plate structures. We welcome studies utilizing ocean-bottom and land-based seismic data to investigate oceanic features, such as SS precursors, ambient noise, and surface wave tomography. Contributions highlighting new geophysical experiments, seismic deployments, and instrumentation are also encouraged, along with any research offering new insights into tectonic processes beneath the global oceans.
This session is jointly organized by the European Seismological Commission and SSA
