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+)

本数据集包含以下内容：1. 由阿纳达科公司（Anadarko）在新西兰飞马盆地（Pegasus Basin）采集的两条地震剖面的经再处理反射地震数据（含经正常时差（NMO）校正的角道集）；2. 基于相似系数（semblance）速度分析得到的层间纵波低频速度模型；3. 通过地质统计地震振幅随角变化（amplitude-versus-angle，AVA）及岩石物理反演，由地震数据得到的岩石弹性模型（共32组实现），涵盖纵波速度、横波速度、密度、天然气水合物饱和度及孔隙度参数；4. 适用于地震及岩石物理反演的Matlab代码（版本2016及以上）
