Supporting data for "Imaging subsoil density variability: specific considerations in 2D FWI"-Chapter 2

This dataset contains the supporting materials for Chapter 2 of Yusuke Kawasaki’s PhD project on the field application of 2D FWI for imaging subsoil density variability. It includes preprocessed seismic data, input files for the FWI workflow, inversion results (shear-wave velocity and density models), geotechnical measurements used to verify the FWI outcomes, and the associated codes for FWI and result visualization. The raw seismic data and their description are available at 10.4121/a8553b7e-82ae-4e9b-bc54-2a6b9ca6063c, and the raw geotechnical data and their description are available at 10.4121/c5036e17-938a-4b78-b223-d0ac8f65b702. The dataset supports research aimed at demonstrating key considerations for achieving reliable subsoil density estimation using FWI.
