Seismic data and petroelastic properties of the gas hydrate stability zone at two submarine ridges hosting concentrated hydrate deposits (Glendhu and Honeycomb ridges, southern Hikurangi Margin, New Zealand). Data acquired in 2013/14, reprocessed in 2020

This dataset includes: 1- reprocessed reflection seismic data (NMO corrected angle gathers) of two seismic profiles collected by Anadarko in the Pegasus Basin (New Zealand) 2- interval P-wave velocity low frequency models from semblance-based velocity analysis 3- petroelastic models (32 realizations) obtained from the seismic data through geostatistical seismic amplitude-versus-angle and petrophysical inversion (P-wave velocity, S-wave velocity, density, gas hydrate saturation, porosity) 4- the Matlab code for seismic and petrophysical inversion (version 2016+)
