Quantifying Model and Image Uncertainty for an OBN Dataset in the Norwegian North Sea

Seismic velocity models derived via ray-based tomography and full waveform inversion (FWI) are typically non-unique, as the observed data may be explained by many possible models. Constraints may limit these possibilities, but even then many viable models can appear equally correct. Here the authors present a methodology for quantifying model uncertainty and use the NOAKA ocean bottom node dataset from the Norwegian North Sea to demonstrate their approach.
