Abstract High‐resolution crustal‐scale seismic imaging from long‐offset ocean‐bottom seismometer (OBS) data using full‐waveform inversion (FWI) remains challenging because the large number of propagated wavelengths and waveform complexity make the inversion highly sensitive to time‐shift errors (cycle skipping). To mitigate this nonlinearity, we assess

Diffusion Priors Enhanced Velocity Model Building From Time‐Lag Images Using a Neural Operator
Abstract Velocity model building (VMB) serves as a crucial component for achieving high precision subsurface imaging. However, conventional VMB methods are often computationally expensive and time consuming. In recent years, with the rapid advancement of deep learning, particularly the success of generative models and neural operators (NOs), deep ...

Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.

Abstract Mid‐mantle (660–2,000 km) seismic observations are commonly attributed to thermo‐chemical heterogeneities or phase transitions, yet many observed features remain difficult to reconcile with these mechanisms alone. It has been shown that the depth‐dependent behavior of bridgmanite deformation generates a strain‐induced seismic discontinuity ...
