Geophysical imaging techniques are widely used to characterize and monitor structures and processes in the shallow subsurface. Methods include active imaging using seismic, (complex) electrical resistivity, electromagnetic, and ground-penetrating radar methods, as well as passive monitoring based on ambient noise or electrical self-potentials. Advances in experimental design, instrumentation, data acquisition, data processing, numerical modeling, open hardware and software, and inversion push the limits of spatial and temporal resolution. Nonetheless, the interpretation of geophysical images often remains ambiguous. Persistent challenges addressed in this session include optimal data acquisition strategies, (automated) data processing and error quantification, spatial and temporal regularization of model parameters, integration of non-geophysical measurements and geological/process realism into the imaging procedure, joint inversion, as well as the quantitative interpretation of tomograms through suitable petrophysical relations.

In light of these topics, we invite submissions concerning a broad spectrum of near-surface geophysical imaging developments and applications at different spatial and temporal scales. Novel developments in the combination of complementary measurement methods, machine learning, and process monitoring applications are particularly welcome.
