Seismic Array HiKurangi Experiment (SAHKE) data

, , , &
This is the data collected by a major controlled-source and passive seismic imaging experiment, the Seismic Array HiKurangi Experiment (SAHKE). The SAHKE project was designed to investigate the physical parameters controlling locking at the plate boundary beneath the southern North Island and characterise slip processes in a major segment of the Hikurangi system. The components of data were acquired between November 2009 and April 2010 by GNS Science, Victoria University of Wellington, and Earthquake Research...

A 3D gas hydrate model of the southern Hikurangi Margin

Karsten F Kroeger, Gareth J Crutchley, Richard L Kellett & P Barnes
This dataset contains underlying data and results of 3D gas hydrate modelling at the southern Hikurangi Margin using PetroMod™ software and accompanies a manuscript published in the Geochemistry Geophysics Geosystems journal (DOI10.1029/2019GC008275). The model integrates thermal and microbial gas generation, migration and hydrate formation. Modelling these processes has improved the understanding of factors controlling hydrate distribution. Three spatial trends of concentrated hydrate occurrence are predicted. The first trend (I) is aligned with the principal deformation...

Gravity survey data

A catalogue of over 40,000 gravity survey observations in New Zealand, including free air, Bouguer and isostatic gravity anomalies has been assembled. These data have been assembled from survey measurements mostly made by Geophysics Division, Department of Scientific and Industrial Research, (now GNS Science) since the 1940s using a variety of meters. Some gravity data has been contributed by petroleum explorers and universities. In 2004 all data were uniformly reprocessed using GNS Science software and...

Seismogenesis at Hikurangi Integrated Research Experiment (SHIRE) offshore data

, , &
This is the offshore dataset of a large onshore-offshore seismic experiment on the Hikurangi margin of North Island, New Zealand, with a team of scientists from New Zealand, the United States, and Japan. This data acquisition was part of the SHIRE project (“Seismogenesis at Hikurangi Integrated Research Experiment”) and occurred in 2017. The goals of this Earth science project were: 1) to obtain constraints on the deep structure of the Hikurangi margin, with an emphasis...

Reference gravity stations

A catalogue of reference gravity stations in New Zealand has been assembled from measurements made since the 1950s using mostly Lacoste and Romberg D- and G-model meters. These data are from the New Zealand Primary Gravity Network and GNS Science gravity stations for measuring secular changes in gravity. In 2004 the observation data were uniformly processed using GNS Science software and tied to gravity base stations in Auckland and Dunedin. The 2004 revised gravity values...
