Two-dimensional P-wave and S-wave velocity models of the central Hikurangi convergent margin, New Zealand (2021)

These two-dimensional P-wave and S-wave velocity models are derived from elastic full-waveform inversion of downward extrapolated (Synthetic Ocean Bottom Experiment) multichannel seismic data along profile 05CM-38, central Hikurangi convergent margin, New Zealand. The data file is in ASCII format with four columns: X-axis in m, Z-axis in m, P-wave velocity m/s, S-wave velocity m/s. Seismic line 05CM-38 was collected as part of the 05CM survey in 2005 by GNS Science and the New Zealand Ministry of Economic Development. All multichannel seismic field data, seismic navigation and acquisition logs from the 05CM experiment are archived with the New Zealand government and freely available at https://data.nzpam.govt.nz/GOLD/system/. Funding for the generation of the seismic velocity models was provided by the Institute for Geophysics at UT Austin.
