The combination of conventional FWI and adaptive waveform inversion is used to invert a broad-band narrow azimuth shallow-water towed-streamer dataset, recovering an accurate velocity model, to 20 Hz, above, within and below high velocity chalk to a total depth of around 5000 m. FWI alone cannot achieve this depth of penetration from this dataset.
