SM4.4

Geophysical imaging techniques such as seismic, (complex) electrical resistivity, electromagnetic, and ground-penetrating radar methods are widely used to characterize structures and processes in the shallow subsurface. Advances in experimental design, instrumentation, data acquisition, data processing, numerical modeling, and inversion constantly push the limits of spatial and temporal resolution. Despite these advances, 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, appropriate spatial and temporal regularization of model parameters, integration of prior information and non-geophysical measurements into the imaging process, joint inversion, Bayesian inference, 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 methods and applications at different spatial and temporal scales. Novel developments in the combination of complementary measurement methods and process-monitoring applications are particularly welcome.
